Lilium longiforum a potential ornamental plant that has been developed in several indusrtry, such as pharmaceutical industry and floriculture industry. Generative propagation of L. longiflorum is difficult and more effective when propagated asexually through tissue culture techniques. This research aimed to analyze callus induction from L. longiflorum bulb scale and its growth response to the addition of auxin and cytokinin in culture media. This research were tested in two treatments: MS + 3.0 mg L-1 2.4-D + 0.5 mg L-1 BAP, incubated in dark condition for 24 hours (treatment 1) and MS + 1.5 mg L-12.4-D + 1.0 mg L-1BAP, photoperiod 16/8 h (treatment 2). Furthermore, calli were planted on regeneration media (MS + 3.4 mg L-1BAP + 0.09 mg L-1NAA). The result showed that explant in treatment 2 (MS + 1.5 mg L-12.4-D + 1.0 mg L-1BAP, photoperiod 16/8 hours dark/light) is more responsive than treatment 1 on callus induction and subculture treatment. This treatment also produced good quality of calli which were shown in a compact texture, yellowish green colour and 100% survived. Regeneration media succeeded in regenerating calli into indirect shoots by 100%, even though no direct shoots and roots were found in this experiment. This research suggest that treatment 2 can used as an effective protocol on developing L. longiflorum.

Black rice still contains epidermis which is composed of several layers, including pericarp, lemma, aleuron and testa so that cooking takes a long time. To speed up the cooking time on rice can be modified by parboiling process so that it changes the character of gelatinization. The research aims to find out the effect of the concentration of sodium citrate solution and immersion time on the process of black rice parboiled Sirampog varieties on its gelatinization properties. Soaking in sodium citrate solution at a certain time is expected to accelerate the cooking time of black rice. The research using Completely Randomized Factorial design consisting of concentration of sodium citrate solution (0, 3, 5 and 7%) and immersion time (20, 30 and 40 minutes). The variables observed were gelatinization properties including gelatinization temperature, peak viscosity, final viscosity, breakdown viscosity, trough viscosity and setback viscosity. The results showed that the setback viscosity and peak viscosity of Sirampog rice were affected by the concentration of sodium citrate. The sodium citrate solution of 5% as a marinade produces Sirampog varieties of parboiled rice with high trough viscosity and lowest setback viscosity, which means it is easier to cook and more resistant to retrogradation during cooling.

One of the problems for phosphate fertilizing in ultisol soil is Al and Fe bounding and could be overcome by phosphate solubilizing bacteria activity.This study aimed to obtain the best dose of phosphate fertilizer with phosphate solubilizing bacteria for the production of upland rice seeds of the UBB1 PBM variety (Bangka Belitung University red rice 1) and its effect on seed quality. The research was carried out at the Research and Experimental Gardens – Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung, from August to December 2020. The design used was a split plot design, the main plot was phosphate solubilizing bacteria (treatment and control), and the subplots were fertilizers. phosphate (P1– quarter dose, P2– half dose, P2–three-quarter dose, P4– full dose). Seeds produced in the field were tested in the laboratory for viability and vigor. In the field, phosphate solubilizing bacteria (Burkholderia sp) can replace half the dose of phosphate fertilizer. This was indicated by the seed weight of plant-1 which did not differ between full dose + control and half dose + treatment. This fact was also identified in the viability and vigor of the seeds in laboratory testing. There was no significant difference in germination rate and vigor index between the two treatments. This finding shows that phosphate solubilizing bacteria can be applied for efficiency of phosphate fertilization and guaranteeing seed production and seed quality

Waste is a major problem that is often faced by Indonesian people. The existence of waste that has not been handled properly will have a negative impact on the quality of the community's environment. Waste handling with the bioconversion method with the help of Black soldier Fly (BSF) larvae and EM-4 bio-activator can minimize waste capacity and be useful for the community. This study aims to compare the ability between bioconversion agent and quality of various types of organic waste that use for bioconversion. The research was conducted in January – August 2022 at Experimental dan Research Garden (KP2) Universitas Bangka Belitung and Laboratory of Indonesian Center for Biodiversity and Biotechnology. This study used a factorial randomized block design (RAKF) with 2 factors. The first factor were bioconversion agents consist of 3 levels, P0 (control), P1 (EM-4 activator) (15 ml), P2 (Black Soldier Fly) (5 grams/bio-pond). The second factor were different kind of organic waste materials consists of 3 levels, L1 (pineapple peel waste), L2 (orange peel waste), L3 (bagasse). The results showed that BSF larvae had a potential as bioconversion agent and its ability close to EM-4. Generally, application of bioconversion agent increased the quality of compost compare to without application of bioconversion agent.  Application of bioconversion agent combined with pineapple peel waste had quality close to standards from Ministry of Agriculture No. 261, 2019.

Mungbean is one of the main commodity which are planted in the dry season after planting rice. Even though having a high marketable value, the productivity of mungbean is still quite low because the farmers rarely provide enough fertilizer dosage and use the low growed seeds which resulted directly to the low quality or productivity. This study aims to determine the response of three mungbean varieties in paddy fields with five levels of NPKS (15:15:15:10) fertilizers. The study was consisted of three varieties (Vima-1, 2, 4) and five doses of NPKS fertilizer (100, 200, 300, 400, 500 kg ha-1). The study was applied to the randomized completely block design with three replications. The results showed that plant height, number of clusters, biomass dry weight, and seed yield ha-1 of mungbean are significant different between Vima-1, Vima-2 and Vima-4 varieties, while the addition of NPKS inorganic fertilizers could increase plant height and root weight. The interactions between varieties and the NPKS fertilizer dosage was experienced in the number of pods and seed weight per plant. The highest yield of mungbean was resulted in Vima-1 (2.18 tons ha-1) whereas the lowest yield was obtained by Vima-2 which resulted in seed 1.42 tons ha-1. The application of inorganic fertilizer NPKS (15:15:15:10) 100 kg ha-1 has quite enough to produce an optimum productivity of mungbean in Malang rice fields.

The development of the Ulap Doyo weaving industry in East Kalimantan is constrained by doyo plants availability as raw material. Cultivation of Doyo or Marasi plant conventionally faces obstacles due to the low germination rate and deteriotation of doyo seeds. Tissue culture is considered as an important technology for mass propagation producing disease-free, high quality, uniform and rapid production of planting material. This study aims to induce regeneration and increase the multiplication of doyo plant for mass multiplication to support the doyo plant conservation program. The research was conducted in 3 stages: shoot initiation, shoot multiplication and plant regeneration (root induction). Shoot initiation and multiplication experiments were carried out using several combinations of 6-Benzylaminopurine (BAP) and Indole-3-butyric acid (IBA) in solid MS media, and two explants types, shoots and rhizomes. The root induction was carried out by growing the plants in MS media containing 0.25 mg L-1 IBA. The results showed that the rhizome was the best part of the plant as a source of explants in doyo plant tissue culture. Initiation medium of 3.75 mg L-1 BAP + 0.50 mg L-1 IBA and the multiplication medium of  37.50 mg L-1 BAP + 0.50 mg L-1 IBA, gave the best effect resulting in the highest survival and responsiveness percentage (80%), percentage of shoot producing explants( 60%, and number of shoots per explant ( 4.00). The plant regeneration has good potential for doyo plant mass propagation, in which 87.50% of the resulting shoots were able to form good root system.

Biotic and abiotic stress during cultivation is one of the challenges in increasing upland rice production. Stress can be mild to severe, potentially reducing yield. Knowing the ability of plants to adapt to stressful environments from the start is essential information in the assembly of new high-yielding varieties. This study aims to determine stress in 36 upland rice lines and the adaptability of several upland rice lines to environmental stress. The genetic material used was 36 upland rice lines and two comparison varieties with four replications. The line is planted in Lampung, DI. Yogyakarta and East Java, two locations each. That area has different soil types and elevations. Data were analyzed descriptively and tabulated. In addition, the average scoring of biotic and abiotic stress for each location was calculated. The results showed that biotic stresses found in the plantations were Leaf Blast, Neck Blast, Bacterial Leaf Blight, Brown Spot, Red Striped, Rats, Birds, Rice Leaf Roller, and Stem Borer. Meanwhile, the abiotic stresses found were drought and salinity. From 36 tested lines, it showed that G26 was resistant to biotic stress caused by pests and diseases, G29 was drought-tolerant, and G6 was salinity tolerant.
