Kitolod (Hippobroma longiflora (L.) G. Don) is a wild plant. Its flower is widely used as a traditional medicine. When this plant is utilized more intensively, there may be a shortage of the plant due to the lack of seed sources. This study aimed to obtain the best techniques and culture conditions for in vitro propagation of kitolod to provide a large number of planting materials. The experiments were arranged using a completely randomized design with two treatment factors and 10 replications for all experiments except in shoot rooting. Leaves and petioles were used as explant sources. Various combinations of benzilamino purine (BAP) and naphtalene acetic acid (NAA) were applied. Leaf explants in Murashige and Skoog (MS) medium enriched with 1 mg/L BAP and 0.1 mg/L NAA combination produced the highest number of adventitious shoots per explant, but 2 mg/L BAP + 0.1 mg/L NAA was more effective for shoot initiation and multiplication. The latter medium was also able to produce the tallest shoots, and presented 75% of successful rate over the acclimatization period. The best rooting was provided by MS medium added with 0.5-1.0 mg/L NAA.

Lipolytic bacteria attract great attention to various biotechnology industries because of their enzymatic potential. This study aims to isolate and identify lipolytic bacteria from cashew nutshell waste using the 16S rRNA gene as a molecular marker. Lipolytic bacteria were isolated using serial dilutions and inoculated on lipolytic media. A total of 3 isolates of lipolytic bacteria were obtained from cashew nutshell waste based on screening in LA Rhodamine B. The partial sequence of 16S rRNA gene from LB15 amplified using a pair of primers 63F and 1387R having a size of 1238 bp, while BL6 and BK6 were 1283 bp, respectively. Based on genetic distance analysis and phylogenetic reconstruction, we proposed that LB15 be identified as Burkholderia sp. with 99.92% similarity. In addition, because the 16S rRNA gene sequence similarity of BL6 was 99.87% with Paraburkholderia kururiensis strain 979, BL6 was classified as Paraburkholderia kururiensis. Then, isolate BK6 was identified as Ralstonia sp. with a similarity of 99.53%. The similarity value can be used as a reference in determining the identity of bacteria. A bacterium can be categorized as the same species if it has a similarity value of more than 99%.

Physical activity is defined as any bodily movement produced by skeletal muscles. Several factors can influence a person's physical activity levels, one of them is work from home (WFH) policy caused by Covid-19. This policy could reduce a person’s physical activity. To maintain health during the Covid-19 pandemic, most people access the internet to find health-related information. However, there is no information about the physical activity level and the relationship between physical activity and health-related internet usage during the Covid-19 pandemic in Indonesian society. This study asked 83 participants from 32 cities in Indonesia to fill the questionnaire related to their activity using the International Physical Activity Questionnaire (IPAQ) and the purpose of internet usage. Most of the respondents had moderate activity levels. Females were more active than males during the Covid-19 pandemic. A higher intensity of working from home negatively correlated with a physical activity score, however, it was not statistically significant. People who used the internet to search for a healthy diet and healthy life information were more physically active than those who did not. Thus, we assumed that people who used the internet to search for a healthy diet and healthy life information have high awareness about their health.

Weaver ants Oecophylla smaragdina are social insects that recognize nestmates using pheromone. This study analyzes the feeding behavior and nestmate recognition of weaver ants in the urban area of three different islands (Sumatra: Baturaja; Java: Banyuwangi; Papua: Sorong). The free ants were placed in the arena composed of chicken meat, sugar, bananas as the baits. Ten trapped ants were also located in the arena to explore the nestmate recognition between the free and the trapped ants. Five types of behaviors, i.e., approach, stalking, communication, competition, and agonistic, were recorded in 6 days. Food preferences were indicated by the number of conduct towards the feeding sites, and nestmate recognition was indicated by approaching the trapped nestmate. The results showed that the percentage of the approach behavior of free ants was the highest in the three islands but had no significant difference between Sumatra and Java and between Java and Sorong (p-value >0.05). However, the study showed significant differences for the other four behaviors observed. As predicted, the percentage of chicken meat foraged by the ants was the highest due to the carnivorous behavior. The free ants showed the nestmate recognition to the trapped ants in all behavior, except competition.

Arbuscular mycorrhizal (AM) fungi form mutualistic symbiosis with root of host plant. Staining technique to detect AM fungi usually used hazardous chemical. The ink stain and vinegar were used as an alternative technique to replace trypan blue and lactic acid in root staining method. This study aimed to determine time for clearing root cell contents and ink stain type to visualize the best AM fungal structures within the root observed under light microscope. Pueraria phaseoloides var. javanica roots colonized by AM fungi were cut into 1 cm long, cleared in KOH solution and stained. Four clearing time were done vis 5, 10, 15 and 20 minutes, and four stains were used namely Shaeffer black ink, Parker Quink blue ink, blue stamp ink, and trypan blue. Twenty stained roots were taken randomly from each tratment, and observed. Root clearing process for 20 minutes showed the best result. Only Shaeffer black ink and trypan blue produced clear structure of external hyphae, internal hyphae, vesicles and arbuscules. Arbuscular structure stained only by Shaeffer black ink and trypan blue. This indicated that Shaeffer black ink could be used as an alternative stain to detect AM fungi within the root of host plant

Cockatoo (Cacatua sp.) is one of birds that is widely distributed in Indonesia and often kept as pet, thus threatening the Cacatua population in the wild. Environmental condition may affect the behavior of Cockatoo. Some unnatural behavior may arise due to living in the captive. Different cage conditions may result in different behavior performance in Cockatoo. Research on daily behavior at animal rescue sites at ASTI Bogor has never been conducted. This study aimed to analyze natural and stereotype behavior of Cacatua sp. at animal rescue center due to foreclosure, and analyze the relationship between cage condition and environmental factors. This study used focal instantaneous sampling, using eight individuals Cacatua sp. Cacatua sp. in ASTI performed natural behavior more than unnatural behavior, therefore ASTI can be a good place for animal rescue. The dominant natural behaviors were Resting (Re), Preening (Pr), Feeding (Fe), Locomotion (Lo), and Fighting (Fg), while unnatural behaviors were play, bite, abnormal vocalization, feather picking and aggressive. There are no difference in behavior between male and female, and also behavior in the morning and afternoon (p>0.05), but cage condition had a significant effect to daily behavior of Cacatua sp. (<0.05).

Probiotics are living microorganisms if consumed in sufficient quantities can be beneficial for health. One of the potential bacteria as probiotics is Lactobacillus plantarum NHC6 is a lactic acid bacteria isolated from pineapple juice. This study aimed to test the ability of L. plantarum NHC6 as a probiotic in pineapple juice. Probiotics were stored until four weeks under 4°C and 10°C which weekly is monitored data on the amount of microbes, pH, percentage of lactic acid, and total dissolved solids in fermented pineapple juice. The result shows, the shelf time for pineapple juice under 4°C has a lower microbial reduction time rather than the juice storage under 10°C. Probiotics shelf time predicted for 4°C storage was 28.32 weeks and for 10°C storage was 8.67 weeks after production. The changes in physical properties (pH, percentage of lactic acid, and total soluble solids) in 10°C storage is much faster than that off in 4°C, this happens because there is still metabolic activity by bacteria at that temperature.

Aquilaria crassna is one of the Aquilaria species that could produce agarwood. agarwood production of A. crassna can be induced by microfungi as an inoculant. Ecological interaction between the host plant, wounding and inoculant in the formation of agarwood has not yet clearly. other factors like the plant ages, plant species, environ- ment also played important roles in the formation of agarwood. This research aimed to determine the influence of the combination between planting media and Acremonium sp. and Fusarium sp. to agarwood quality of Aquilaria crassna. The experiment was consisted of two factors, which were five planting media and two inoculants fungi i.e. Acremonium sp. and Fusarium sp. The observed parameters were the percentage of senescence leaves, color of wood, level of fragrant and terpenoid content. The best agarwood fragrant was produced by the seedlings that were treated with either combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp. or the combina- tion between husk charcoal media enriched with Hoagland modified solution and Fusarium sp.. The darkest color of wood was produced by the seedlings that were treated with combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp., as well as for the same media with Fusarium sp.. during the experiment terpenoid could not be detected from the treated seedlings. Acremonium sp. caused more leave senescence than that of Fusarium sp..

Xylanase is an extracellular enzymes that can be produced by microbes which capable to degrade xylan into xilo-oligosaccharides (XOS) and xylose. Application of xylanase is still not optimal due to the lack of availability of superior microbial cultures producing xylanase. The purpose of this study was to determine the characteristics of xylanase produced by bacteria isolated from Forest land Bukit Duabelas National Park, Jambi, Indonesia. Xylanase produced by bacterial isolate XJ20 was selected for further enzymatic activity and characteritics assays. Xylanolytic activity was measured by using the 3.5-dinitrosalicylic acid (DNS) assay. High activity of xylanase was recorded at three times of incubation, which were 6 (0.015 U/mL), 14 (0.012 U/mL) and 20 (0.007 U/mL). The first peak and the second peak reached the highest activity at a temperature of 70 °C, however, the first peak reached the highest activity at pH 4.0 and a second peak at pH 7.0. pH 4.0 xylanase were incubated at room temperature and 70 °C has a half time consecutive 9 hours and 6 hours, whereas at pH 7.0, has a half time consecutive 4 hours and 3 hours.

Bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the important diseases in rice crops in Indonesia. The disease is difficult to be controlled since it attacks the rice plant at different growth stages such as tillering, flowering and ripening. One of the alternatives that could be used to control the disease is by using phyllosphere bacteria as the biocontrol agents. This study aims to isolate, characterize and screen the rice phyllosphere bacteria producing bioactive compounds against Xoo. Phyllosphere bacteria isolated from healthy leaves of rice var. Ciherang by using 4 different media obtained 285 bacterial isolates which were consisted of the 65 isolates of King’s B agar, 86 isolates of Nutrient agar, 81 isolates of Luria-Bertani agar, and 53 isolates of Trypticase Soy agar media. Antagonist test using double layer method showed 58 isolates of phyllosphere bacteria produced bioactive compounds that inhibited the growth of Xoo. Pathogenicity test agaist rice leaf revealed 18 bacterial isolates did not perform their potencies as pathogenic bacteria. Among the 18 non-phytopathogenic bacterial isolates, 14 isolates belong to Gram-positive bacteria and 4 isolates belong to Gram-negative bacteria. Five isolates among Gram positive bacteria were predicted as Bacillus genera.

Selaginella, a genus of Pteridophyte, is known as an herb that contains of several bioactive compounds. The growth and bioactive compounds of plant were affected by plant environment, such as media types. The objective of the research was to obtain an appropriate plant media for growing S. plana dan S. willdenovii, and its effect on the content of bioactive compounds. The experiment consisted of two factors, plant growth media and the species of Selaginella. The first factor consisted of eight plant growth media, i.e.: soil, rice husk, rice husk : soil = 1:1 (v/v), burned rice husk, soil : burned rice huks = 1:1 (v/v), burned rice husk : rice husk = 1:1 (v/v), burned rice husk : rice husk = 3:1 (v/v), and burned rice husk : rice husk = 1:3 (v/v). The second factor was two spesies of Selaginella, i.e.: S. plana and S. willdenovii. Ethanol extract of Selaginella was qualitatively analyzed for flavonoid, tannin, and saponin content. The result showed that both fresh and dry weights of Selaginella were influenced by the type of plant media, Selaginella species, and their interactions. S. plana and S. willdenovii grew best on medium containing soil: burned rice = 1:1 (v/v). The highest flavonoid content of S. plana and S. willdenovii was also obtained from the plant grown on the same media. Comparing to the bioactive compound content of natural plant, saponin content of S. plana and S. willdenovii was increased by the treatment of plant media. The treatment also increased tannin content of S. plana, but not of S. willdenovii.

Hydrilla verticillata is an aquatic weed, can build symbiosis and also become a substrate of freshwater fungi. Some of freshwater fungi that live in association with H. verticillata are pathogenic fungi which were potentially used as controller for Fusarium oxysporum and Ganoderma boninense. The use of pathogenic fungi as a biocontrol is not consistent in the field. Therefore, this research aimed to find new fungus candidates that are stronger and more consistent in controlling pathogenic fungi. Freshwater fungi were isolated from H. verticillata. Identification was based on morphological characters. Molecular analysis was carried out for freshwater fungi which had the highest inhibition percentage to pathogenic fungi. The antagonism test was conducted by dual culture method. The mechanism of interaction of hyphae was observed under a microscope. Freshwater fungi was derived from H. verticillata stem are Aspergillus section flavi, Gliomastix sp., and Talaromyces sp. Antagonism test results showed that all fungi could inhibit the growth of pathogenic fungi. Based on molecular analysis used ITS region showed Talaromyces sp. could not identify to the level of species so that additional genes were required, namely beta-tubulin gene, in order to further identify Talaromyces sp.

Gayo-arabica coffee is a typical arabica coffee which widely used by Gayo people in Aceh, Indonesia. The coffee plants also grow in Gayo. However, it has not clearly understood its effect for health. The study aimed is to analyze the Gayo-arabica coffee consumption on the levels of malondialdehyde (MDA) as an indicator of damage cells due to oxidative stress and superoxide dismutase (SOD) as a marker of antioxidant enzyme, after performing a single bout submaximal physical exercise. Male sedentary subjects (21-27 y.o), consisted of 36 men, divided into 3 groups: control (zero of coffee), Gayo1 (15 g coffee in 200 ml water), and Gayo2 (20 g coffee in 200 ml water). Coffee was given once, after rockport test as a single bout submaximal physical exercise. MDA serum and SOD serum were taken after 1 hour of coffee drinking. MDA serum decreased significantly in Gayo1 (8.01 uM) and Gayo2 (10.36 uM), compared to control (26.82 uM). SOD serum increased significantly in Gayo1 (114.81 ng/ ml) and Gayo2 (101.48 ng/ml), compared to control (24.024 ng/ml). Nevertheless, there was no significantly different between Gayo1 and Gayo2 on MDA and SOD serum (p≥0.05). We suggest that the Gayo-arabica coffee after single bout submaximal exercise can diminish stress oxidative in sedentary people.

Crested macaque (Macaca nigra), one of the seven endemic primates in Sulawesi is the most endangered macaque species that has been categorized as critically endangered by International Union for Conservation of Nature (IUCN). However, almost nothing is known about the reproductive biology in associated with the behavioral during pregnancy. The data is important to support a management and breeding programs such as pregnancy diagnostic and conservation program in this species. The research aimed was to study the behavior of the crested macaques during pregnancy. Observations were performed on the 10 adult females of the group of Rambo 1 (R1) which has been habituated at Tangkoko-Batuangus Nature Reserve, North Sulawesi. Behavioral data were collected using focal animal sampling and recorded using instantanaeous sampling on females during menstrual cycling, pregnancy, and after parturition (lactation). During five months observations, a total of 393.63 observation hours were recorded. The results showed that daily activities of the M. nigra during menstrual cycling were dominated by feeding (26.60%), foraging (15.95%), and locomotion (16.16%). Daily activities during pregnancy was dominated by feeding (27.03%), foraging (16.37%), and resting (13.45%), whereas after parturition (lactation) period is dominated by resting (26.12%), foraging (19.51%), and feeding (14.98%). The resting was the most activity in the end of pregnancy and few day after parturition. The diets were collected successfully composed of the fruits (34 species), arthropods (3 species, 2 families, 4 orders), fungi (4 genus), and plants (5 species). Climate was influenced on the composition of the diet, especially on fruit and arthropods. In conclusion, the activity budgets were different during menstrual cycling, pregnancy, and lactation, especially feeding, foraging, locomotion, and resting.

Nyamplung (Calophyllum inophyllum), a non-edible producing plant, is a tropical plant traditionally used by local residents as firewood, building material and medicinal plants. The research aimed to study the development of flower and fruit as well as oil content of nyamplung seeds. Two adult trees (P1 and P2) with different provenance were used in experiment. Morphology of flower and fruit, and seed germination were observed from the field, while the microscopic anatomical observations and oil content analysis were carried out in the laboratory. The result showed that a single generative bud generally had 8-15 flowers. The flower was arranged in bunches, with 4 petals, 4 sepals, single pistil and 4 files of anthers surrounded the pistil. In some cases, the flowers had 5 sepals, or 3 sepals and 3 anthers files. Fruits were round, green and turned to harden with brownish color during maturation. Flower bud grown from bud was ready to blossom 27 days after initiation (DAI). There were up to 48.52% flower buds drop at 24 DAI, and they were still increase up to 64.5% flower drop during the whole of flower development. The observation also showed that fruit drop rate of P2 plant was higher than P1. After flower bloom for 3 or 4 days after anthesis, the flowers started to lose their parts. The fruits started to ripe 8-10 week after anthesis (WAA). Seeds from P2 tree had oil content of 51.79%, which was higher than the P1 tree (42.57%).

This research aims is to find starter for sorghum fermentation and to observe its influence in fermentation process and tannin level in sorghum flour. Four isolates of Lactic Acid Bacteria were tested as starter for Numbu and Kawali sorghum grain fermentation. The criteria was the ability to produce acid and cell viability. The fermentation used four treatments in duplicates. The selected isolate was inoculated into dehulled and non-dehulled sorghum grain. The fermentation time were 0, 24, and 48 h. Analysis were pH, total acidity, total sugar, viable cell, tannin level, structure of sorghum flour, the yield of flour passed 80 mesh, and flour moisture. The results showed that E1222 was selected as a starter for Numbu sorghum grain fermentation while E5 was selected for Kawali. The starter can decrease pH value, increasing total acidity, decreasing total sugar, however there was no significant difference in viable cell in fermentation process. It decreased tannin level approximately 90% in Numbu fermented flour and 77% in Kawali. There was corrosion in starch structure of fermented flour, while the yield of flour passing through 80 mesh was increased. The best treatment was fermentation of dehulled and inoculated sorghum grain (So-St) in both of sorghum varieties.

This research aimed to confirm the tendency of mice to novel object, effect of exercise (in running-wheel) toward memory of mice and to test tendency of mice in avoiding predator signal in novel object. Novel object recognition test (NORT) used to test the memory the day after acquisition phase (NORT I) and memory one week after exercise was given (running-wheel) (NORT II). The result showed that there was no tendency of mice in exploring toward novel object in both NORT I and NORT II. This might happen because the complexity of familiar object higher than novel object, so the familiar object could accommodate more activities. Exercise using running-wheel in mice had an effect on memory, it could be seen in decreasing duration of object exploration time from NORT I to NORT II. There was no tendency in avoiding predator’s signal on novel object which was attached by urine addition (odor signal).

Betel nut (Areca catechu) was proven to have antihyperglycemic activity through increased PI3K pathway in the GLUT4 translocation in cells. However, research on the ethanol extract of betel nut in Indonesia is still limited. The main problem in this study was whether the ethanol extract of betel nut could improve glucose tolerance in a two-hour postprandial period and whether the ethanol extract of betel nut could induce GLUT4 translocation in skeletal muscle cells of mice induced hyperglycemia. Glucose tolerance test results showed that treatment of the ethanol extract of betel nut for 24 days with all doses tested: P50,100,150,200 and 250 mg/kg body weight could improve glucose tolerance in a two-hour postprandial period. The protein electrophoresis of that fasting and one hour postprandial state treatments resulted an increase in GLUT4/βActin density ratio of P250 group compared to negative and positive controls. In this case, GLUT4/βActin density ratio of P100,P200 and P250 were higher than that GLUT4/βActin density ratio of P50 and P150. Increased in GLUT4/βActin density ratio showed enhancement of the GLUT4 in skeletal muscle cells in fasting and one hour postprandial state after treated with ethanol extract of betel nut.

High methane oxidation activity of local isolated methanotrophic bacteria have a potent as methane gases reducing agent while combined with nitrogen fixing bacteria as paddy biofertilizer. The aim of the research was to evaluate the effectiveness of the bacteria as methane gases reducing agent and biofertilizer in paddy plantation. The research was arranged in a completely randomized design consisted of fertilizer types and watering system treatments with four replicates. The research showed that paddy shoot length was not affected by the treatment. On the other hand, both plant freshand dry weight, as well as the number of productive tiller were affected by interaction of fertilizer types and watering system. Fertilizer types affected grain per panicle and methane flux after fertilization. In the end of paddy vegetative stage, bacterial fertilizers were capable to reduce methane emission in different rate. The different result in methane flux was likely due to the interaction between soil local microorganisms and soil chemical component.

Some of Gram-negative bacteria perform a phenomenon called quorum sensing (QS) to activate certain phenotypes such as pathogenicity. The bacterial cells performing QS produce N-acyl homoserine lactone (AHL) as signal molecules to communicate within a population. These molecules can be degraded by the enzyme, i.e. AHL lactonase. This study aimed to characterize the activity of AHL lactonase from Bacillus cereus INT1c and Bacillus sp. NTT3a in different pH and temperature levels. Both strains produce AHL-lactonase that could be found in intracellular and extracellular extracts. The dialysis process of extracellular AHL-lactonase of INT1c significantly increased the specific activity from 5.91 to 29.96, different from an extracellular enzyme of NTT3a that slightly increased from 4.08 to 5.39. Generally dialyzedAHL-lactonase of both B. cereus INT1c and Bacillus sp. NTT3a had activity in wide pH range with better activity in acidic pH and were not stable in high temperature with the highest activity at 30-40 oC.

Indonesia is one of the largest pepper producing countries in the world. One of the pepper-producing provinces in Indonesia is the Bangka Belitung Islands (Babel). However, the infection of Radopholus similis and Meloidogyne spp. which causes yellow disease becomes one of obstacles in pepper cultivation in Babel. Thus, alternative solution to overcome this yellow disease is by reducing the amount of nematode inoculum of R. similis and Meloidogyne spp. in soil. This study aimed to determine the effectiveness of the infusion of oyster mushrooms baglog waste enriched with molasses to control the population of R. similis and Meloidogyne spp. and to increase the population of rhizobacteria. Infusion of oyster mushrooms baglog waste was mixed with 1% of molasses and was poured into soil obtained from the pepper plant roots. The concentrations used were 10%, 20%, 30% and 50%. Population of phytonematode, rhizobacteria, proteolytic bacteria, and group of fluorescence bacteria were calculated before and 7 days after treatment. Results showed that the populations of R. similis and Meloidogyne spp. in the soil poured with the influsion of oyster mushroom baglog waste decreased by 29.11% (R. similis) and 24.61% (Meloidogyne spp.), compared to the before and control treatments. The suppression of nematode population was found to be the highest in the influsion treatment at concentration of 50%. Overall, treatment of all concentrations succeeded to increase the population of rhizobacteria, proteolytic bacteria, and group of fluorescence bacteria in soil. Moreover, the highest increase was found in soil treated with concentration of 50%. This study provided new information that the infusion application of oyster mushrooms baglog waste enriched with molasses had the potential to increase the population of rhizobacteria and suppress the amount of pathogens R. similis and Meloidogyne spp.

The lactic acid bacteria (LAB) and its lactic acid are commonly used to preserve the food and to extend the food’s shelf life. MRS media is a growth medium for LAB, but it is not feasible for industrial scale application. Cheaper substrate from agriculture products is therefore required, such as tofu whey, which is potential to be used as LAB medium. Tofu whey contains important components to support the LAB growth, but it needs C source (5% of glucose) and nitrogen source (1% ammonium sulphate or urea) supplementations. This study aimed to investigate the influence of N-source to Pediococcus pentosaceus growth and its capability in producing acid compounds. The result showed that addition of urea increased pH fermentation, contrarily to that ammonium sulphate supplementation. The highest bacterial growth rate (μmaks) was observed on media with urea (0.43 jam-1), while the highest acid production was occured on media with ammonium sulphate (9.13 mg/mL). Supplementation of ammonium sulphate and urea on tofu whey highly supported the growth of bacterial population for about 6.5 × 108 CFU/mL and 5.4 × 108 CFU/ mL, respectively, but still lower compared to MRS media (2.03 × 1010 CFU/mL).

Sponge-associated actinobacteria may diverse and have potency to produce bioactive compounds. Diversity and antimicrobial activity of indigenous sponge-associated actinobacteria isolated from the marine ecosystem in Indonesia have not much been explored. This work aimed to assess morphological and antibacterial activity of sponge-associated actinobacteria. The morphological characteristics were examined based on their color of aerial and substrate mycelia, and pigmentation, while antibacterial activities were assayed using the antagonist technique. The selected actinobacterial isolate was identified using 16S rRNA gene. Various sponge-associated actinobacteria were successfully isolated from Hyrtios sp., Callyspongia sp., and Neofibularia sp. sponges. A total of 62 actinobacterial isolates were obtained, and each isolate showed a variety of morphological characters, which could be seen in aerial mass color, substrate mass color, and pigmentation. Actinobacterial isolates were tested against human pathogenic bacteria, i.e. Staphylococcus aureus and Methicillin-Resistant S. aureus, representing Gram-positive, and Escherichia coli EPEC K1-1 and Shigella dysenteriae, representing Gram-negative. Most of actinobacterial isolates had antimicrobial activities at least against one of pathogenic bacteria. High activity was shown by NOHa.2, isolated from Neofibularia, and HRHa.5 isolated from Hyrtios. The NOHa.2 showed the highest antimicrobial activity against S. dysenteriae, meanwhile, HRHa.5 showed antimicrobial activity against 3 of 4 tested bacterial pathogens. These data showed diversity of sponge-asccociated actinobacteria from marine ecosystem in Indonesia, and several of them have potency as source of antibacterial compounds

Fermentation of Lactic Acid Bacteria (LAB) Pediococcus pentosaceus can improve the quality of food and its shelf life. Using commercial LAB specific media, de Man Rogosa and Sharpe (MRS) for growth on industrial scale application is not efficient. Tapioca wastewater (TW) still contains some of the nutrients needed for the growth of P. pentosaceus, but needs the enrichment of carbon sources (5% of glucose) and nitrogen sources (ammonium sulfate). This study aimed to use tapioca industrial wastewater with the addition of glucose and ammonium sulfate as an alternative growth media for lactic acid bacteria P. pentosaceus E.1222. The results showed that glucose and nitrogen had no significant effect on the number of bacterial colonies. The highest substrate efficiency was tapioca wastewater (86.81%), MRS broth (53.73%), and TW with 5% of glucose and 1% of ammonium sulfate (43.53%) respectively. Maximum growth rate (μmaks) was found in TW with 5% of glucose and 1% of ammonium sulfate (0,52 hours-1). Increasing the starter volume until 1000 mL in TW with 5% of glucose and 1% of ammonium sulfate showed a slight decrease in the log number of bacteria from 8,836 (50 mL), 8,401 (500 mL), to 8,063 (1000 mL).

Biodiversity is an important aspect which supports life systems on earth as well as maintains ecosystem sustainability and evolution. Fungal communities, in particular, saprophytic fungi, are often ignored during an inventory of biodiversity in the National Park Area. Saprophytic fungi is a fungus obtain nutrients by decomposing dead organisms or other organic material and act as decomposers in the ecosystem. Saprophytic fungi can be found growing on dead organic matter contained in the environment such as soil, wood, and litter. The diversity of Macroscopic saprophytic fungi from Ujung Kulon National Park is reported here. Fungal identification was done by using a variety of macroscopic characters. This study determined eight species that classified into six genera of saprophytic fungi, namely: Collybia, Crepidotus, Hygrocybe, Lepiota, Marasmius, and Mycena. By knowing the diversity of saprophytic fungi, it is expected to add information about biodiversity as a preparation towards the further development of the potential of existing biodiversity in Indonesia.

Agricultural land expansion necessity for food security in Indonesia has been faced by the fact in utilizing marginal land such as shallow peat soil in Central Kalimantan. Among problems encountered in such marginal land are pests and diseases incidence. Farmers practice in dealing with those problems is the chemical pesticides application. Unintended chemical pesticides that fall on/into the soil might have an adverse effect to soil microbes activity. This research aimed to assess the effect of pesticides on functional soil microbes population in peat soil. The research used completely randomized factorial design with two factors. First factor was 7 combinations of types (paraquat and buthylphenylmethyl carbamat (BPMC)) and dosages (50, 100, and 200% of recommended dosage) of pesticides. Second factor was 4 incubation times (1, 7, 14, and 28 days). Following the each of incubation times, the soil samples treated and analyzed for population of phosphate solubilizing microbes, cellulolytic microbes, and N2 fixing bacteria. The results show that phosphate solubilizing fungi population decrease by pesticides treatment. In contrast, pesticides significantly increased the Azospirillum population. Adverse effect to microbes population was found on the first day of incubation, however it recovered at 7 days and longer incubation times. In general, functional microbes population with paraquat application lower than BPMC application.
