Abstract:
Consumption of high nutritional is increasing; therefore, it is necessary to develop pigmented trice variety with high yield, good adaptability, and good grain quality favored by consumer such as soft texture. The development of aromatic rice variety includes crossbreeding, selection, yield trials, resistance test to pest and diseases, physico-chemical properties assay, analyzing of minerals contents and anthocyanin which were done consecutively during 2012 to 2016. The results showed that a promising line of BH39D-MR-11-1-1-6 revealed consistent grain yield in 16 multi-location yield trials both in the dry season and the wet season in average 6.78 t/ha dan 5.35 t/ha, respectively. The line demonstrated its yield potential of 10,67 t/ha, mid-resistance to biotype 1 of brown planthopper, resistance to pathotype III and mid-resistance to pathotype IV and VIII of bacterial leaf blight, and mid-resistance to four races of rice blast (race of 033, 073, 133 and 173). This line had relatively comparable iron content with the check variety of Inpari-5 Merawu but higher in zinc content compared to other lines tested. The dehulled rice was red and contains a high total phenolic compound amounting (5,743 mg AAE/100 g), and its texture was soft and fragrance. The BH39D-MR-11-1-1-6 has been released as new rice variety named as Inpari Arumba and had a great potential to become a national specialty rice choice.

Abstract:
Soybeans are generally cultivated in irrigated and rainfed rice fields after rice harvest and on dry land. This study aims to determine the effect of N fertilizer and several rice varities residues on lowland rice field on the growth and yield of soybean crops. The research was conducted on rice fields after rice harvest in Serdang Village, Beringin District, Deli Serdang Regency (3035’55,90” South Latitude 98053’58,24” East longitude with an elevation of 2.4-meters above sea level). The soybean used is the kipas putih variety. Factorial randomized block design with two factors and three replications. The factor consists of three varieties (V), namely: (V1) Inpari-32, (V2) Inpari-42, and (V3) Inpari IR Nutri Zinc. The second factor consists of seven different doses of N fertilization treatments (P), namely: without N (P1), low N is 95 kg/ha (35-30-30) (P2), standard N is 125 kg/ha (35-45-45) (P3), high N is 155 kg/ha (35-60-60) (P4), standard N with highest N at primordial is 125 kg/ha (35-30-60) (P5), standard N + additional N 30 kg/ha at primordial (35-45-75) (P6), and standard N + additional N 30 kg/ha after primordial (booting stage) with 4 times applicationis 155 kg/ha (35-45-45-30) (P7). Plot size is 5 m x 5 m and between the plots a drainage channel is made of width 0.5 m and depth 0.4 m. Soybean spacing is 0.4 m x 0.2 m and the previous cropping distance when planting rice is 0.2 m x 0.2 m by planting two seeds per hole as well as liquid organic fertilizer applications conducted at 30 and 50 DAP respectively of 315 ml/63 liters of water. The research result indicates the need for N fertilizer on soybean crop after rice in paddy fields with medium soil fertility is not determined by previously planted rice varieties. To achieve optimum soybean yields for each of the former new superior rice varieties, the residue of N fertilization in rice was 125 kg/ha with three times of application according to the plant growth stages plus additional N during booting stages of 30 kg/ha (total 155 kg/ha) in wet season that contribute significantly to increased growth and productivity of soybean on land with medium soil fertility, soybean-rice-rice cropping pattern, and uniform land management.

Abstract:
Organophosphate pesticides are widely used in agriculture asthey are the most toxic insecticides against vertebrates and easily biodegradable in nature. The objective of this study was to determine the organophosphate residue in rice from several rice varieties and behaviors of farmers in using pesticides. The study was conducted in Subang Regency, West Java, from May to June 2020 using a gas chromatography analysis method. The rice samples came from three sub-districts of Subang Regency, namely Ciasem, Purwadadi, and Sagalaherang in Subang Regency. The data collection of farmer behavior in the used of pesticides in rice farming were conducted by purposive sampling using questionnaires and interviews. The results showed that the residual contents of the organophosphate active ingredients(diazinon, chlorpyrifos, and fenitrotion) in Ciherang, Inpari-32 HDB, and IR64 rice varietes were significantly lower than the Maximum Residue Limits (BMR) of each pesticides allowed in agriculture based on the Indonesian National Standard (SNI) 7313: 2008, so it is safe for consumption. The low residue of organophosphate pesticides is related to the behavior of farmers in using pesticides which generally refers to recommendations and most farmers use pesticides according to the concept of integrated pest control, namely the right dose, right time, right type, and right target according to the type of pests and plant diseases.

Abstract:
A part from being famous for its tourism sector, Bali also has a special attraction in its agricultural sector, namely the subak system which has become a world cultural heritage. The sustainability of the Subak must be maintained, one of effort to create it is by maintaining the sustainability of land availability for food production through increasing the rice yields by using superior rice varieties that have the potential to increase farmers' income. Therefore, this study aims to examine the agronomic performance and yield of various superior rice varieties produced by Balitbangtan in the Bali Province. The study was carried out in the area of Bali Province namely Denpasar, Badung, Bangli, Buleleng, Gianyar, Karangasem and Jembrana in 2019 using Randomized Block Design consisting of various superior rice varieties treatments produced by Balitbangtan and cultivated by implementation the Integrated Crop Management technology on 0,5 ha land area in each area namely Towuti, Inpari-16, Inpari-20, Inpari-28, Inpari-43, Inpari-22, Inpari-32, Inpari-33 and the Cigeulis variety as a comparison and repeated five times. The results showed that all the superior rice varieties examined had great adaptability, growth and development were relatively as same as the Cigeulis variety. In addition, all superior rice varieties produced significantly greater yields than the Cigeulis variety therefore it could be considered as substitute for the use of the Cigeulis variety in Bali, especially the Inpari-28 variety which reached 8.24 t/ha, ± 3 t/ha higher than the Cigeulis variety.

Abstract:
Postharvest handling of shelled corn often faces problems caused by fungal attacks during storage, resulting deterioration due to physical and biological damages. This study aimed to identify various pathogenic fungi that infected shelled corn during storage through the characteristics and growth phases of each fungus as well as to find out the interaction between fungi and shelled corn based on the different parts of kernel structure infected by the fungus. The blotter test method (ISTA) was used to isolate the fungal pathogens from infected shelled corn then purified and cultivated on PDA. Subsequent, microscopic and macroscopic observations were made by capturing images for eight days. Observations showed that Aspergillus spp predominantly infected the pericarp of the shelled corn (61%), Penicillium sp (15%) tended to infect the tip cap, Talaromyces sp (13%) on the endosperm, and Rhizopus sp (11%) on the germ. The largest colony areas after 8-day incubation were Rhizopus sp, followed by Aspergillus spp, Talaromyces sp, and Peniillium sp. The fungus growth phase had a logarithmic pattern with different time for each stage. Therefore, this pattern can be used as a reference for proper preventing time in shelled corn storage before the fungi can produce mycotoxins in the stationary phase and also the possibility to use the fungi as biological agents, such as antibiosis, competition, or parasite.

Abstract:
Allelopathy plays an important role in weed control because it reduces dependence use on synthetic herbicide and labor. Some rice varieties release chemical compounds that can inhibit weed growth. The objective of this research was to identify compounds and to determine the rice allelopathic potential of rice root extract. The experiment was conducted in Regional Health Laboratorium Jakarta and ICRR’s greenhouse, West Java. Identification of metabolite compounds in 10 rice root extracts used GCMS. The experiment in the greenhouse used a split plot design with four replications. The main plot was weeds (Echinochloa crus-galli and Monochoria vaginalis), while the subplot was the roots of 10 swamp rice varieties and control. The rice roots were extracted by the maceration method using 80% methanol and evaporated by a rotary evaporator. The root extract was diluted distilled water at a 50% concentration (w/v) and applied to weeds. The experimental unit was 3 pots planted with 5 weed seeds. The research identified 88 compounds in rice root extract and the highest peak area was stigmasterol compound. The inhibitory of growth and dry weight of weeds varied, between 27-44%. Inpara-3, Inpara-4, Inpara-7, Inpara-8, and Inpara-10 were able to inhibit weeds greater and belong to one cluster. The five swamp rice can be chosen to be developed in paddy fields that were dominated by Echinochloa crus-galli and Monochoria vaginalis.

Abstract:
Tungro disease is one of the obstacles to increase the national rice production program. In some areas, this important disease is endemic. On the one hand, some farmers in controlling plant pests and diseases still use pesticides, which negatively impact health and the environment. On the other hand, environmentally friendly tungro disease control technology is available. This study aims to determine an environmentally friendly integrated control technique for tungro disease consisting of resistant varieties, biopesticides, and conservation of natural enemies with flowering plants in suppressing green leafhopper populations and the incidence of tungro transmission in infection-sensitive plant stage. The test area is located in Lanrang,Sidrap at the Experimental field of Tungro Disease Research Station, Lanrang Sidrap, South Sulawesi, Indonesia from April to September 2017, using a split-plot design. Main plots are: 1) Biointensive control plots, using flowering plants (refugia) and pest control with andrometa which is a mixture of the entomopathogenic fungus Metharizium anisopliae and sambiloto extract; 2) Conventional plots, without flowering plants and pest control using pesticides. As sub-plots are rice varieties: 1) TN1, 2) IR64, and 3) Inpari-9 Elo which differ in resistance to tungro. Observations were made at 2, 4, 6, and 8 weeks after planting (MST). The results showed that the population of green leafhoppers in the TN1, both in the bio-intensive control plot and in the conventional control plot, was higher than the other two varieties. The population of natural enemies in bio-intensive control consists of 10 predator families and the conventional control consists of 9 predator families. The effectiveness of bio-intensive control has an effect on decreasing the population of green leafhoppers and the diversity of natural enemies, and has no significant effect on the incidence of tungro transmission, and has no effect on grain yield. Therefore, biointensive control needs to be developed to create a pesticide-free agricultural environment.

Abstract:
Partnerships are instruments to overcome the inability of individual smallholders to solve the development problems associated with agricultural sectors and commodity chains. While vigorously advocated, a sustainable partnership is rare in the Indonesian cassava production and industrial sector. Knowledge of partnership from the sector is also limited. This study explores the reasons for previous partnerships in the cassava production and industrial sector discontinued and examine what factors determine farmers' willingness to partake in partnerships. The study administered a systematic random sampling to survey for 140 cassava farmers in Central and East Lampung Districts from November 2018 to April 2019. Farmers were interviewed and given a structural questionnaire. The quantitative data were analyzed by heckprobit regression. The results of the study show that the partnership ends because the two parties do not have the same vision for working together. Various variables (barriers to selling to non-industries, low prices, inaccurate weighing scales, high transaction costs, and discounted prices.) indicate the complexity of farmers' considerations for joining the partnership. This research impliesthat it is difficult to create partnerships in the future if farmers and industry have different visions and priorities.

Abstract:
Bacterial wilt R. solanacearum is one of the main diseases of peanuts that can reduce crop production. The use of local varieties and plant management can control bacterial wilt disease. Local varieties are one source of germplasm diversity for plant breeding activities. Management such as fertilization is expected to control pests and plant diseases. The aim of the study was to determine the performance of bacterial wilt disease and its effect on the yield of three local peanut varieties in West Nusa Tenggara with the addition of various doses of K fertilizer. The study was conducted at the Narmada Visitor Plot, on 17 January - 29 April 2017. The experiment used a split plot factorial design. The main plots were three varieties of local NTB peanuts, namely local peanuts North Lombok (KLU) (V1), local Bima (V2), and local Pelat (V3). Subplots are four levels of potassium (K) fertilizer dose, namely 0 kg KCl/ha (P1), 20 kg KCl/ha (P2), 40 kg KCl/ha (P3), and 60 kg KCl/ha (P4). Each treatment was repeated five block. The results showed that each local peanut varieties with doses of KCl fertilizer showed bacterial wilt resistance. The lowest transmission of bacterial wilt was in KLU local peanuts with a dose of 0 kg KCl/ha, 20 kg KCl/ha, and 40 kg KCl /ha, Bima at a dose of 40 kg KCl/ha and Pelat at a dose of 60 kg KCl/ha. The application of KCl fertilizer at a dose of 0 kg/ha to 60 kg/ha did not affect the yield and varieties of local peanuts had different weights of 100 seeds in response to the application of K fertilizer, local peanuts KLU and Pelat had the highest weights of 100 seeds at the KCl dose. 40 kg/ha while Bima at a dose of KCl 60 kg/ha.

Abstract:
Jarwo super technology is a combination of superior rice farming technology, including the 2:1 paired rows planting system, high yield potential varieties, bio-decomposers, biological fertilizers, bio-pesticides, and agricultural mechanization application. The assessment aims to determine plant diversity, production increase, and financial feasibility of jarwo super technology rice farming. The assessment was conducted on March-Juni 2017 with the “demplot” method of applied jarwo super technology in Karanganyar Regency, Center of Java. Primary data is growth, production, and rice farming performance at the “demplot”, as well as existing farmer data. Samples were collected purposively, it’s the farmers who carried out the “demplot” and the farmers around the “demplot”, which meant 30 farmers. Data were descriptively analyzed using the average value, RCR, MBCR, net profit value, and BEP. The results showed that the rice yields with jarwo super was 15.63%higher than the existing farmers. Jarwo super rice farming is more efficient and economically feasible with RCR 1.44 value. MBCR is 11.6 value, it that each additional cost of implementing jarwo super rice farming of 1.000 IDR increases income by 11.600 IDR. Proportion of costs increase in jarwo super rice farming is 350.000 IDR, but profits reached 4.077.083 IDR. Net profit value of 1.7 shows that jarwo super rice farming can increase profits. Production level and dry grain harvested price on farmers level were 30.76%higher compared to BEP production and BEP price. Jarwo super rice farming is feasible to develop that because can increase farmer’s production and profits.
