Anthracnose is a disease that attacks papaya fruit while in the field and continues until the fruit is harvested and distributed to the market. Biofungiside made from citronella and green betel was expected to extend the selling papaya at inhibiting the growth of anthracnose. The study was aimed to determine the appropriate concentration of extracts of citronella leaves (Cymbopogon nardus L.) and green betel leaves (Piper betle L.) in inhibiting the growth of C. gloeosporioides as a cause of anthracnose. The extraction was done by boiling the leaves. The test methods used were in vitro and in vivo tests. In vitro tests were carried out to test the effectiveness of citronella leaf extract with concentrations of 5%, 10%, and 10%, 20% concentrations of green betel leaf extract in inhibiting the growth of C. gloeosporioides. The results of the in vitro test showed a significant difference (á = 0.5%) between treatments with the highest effectiveness value being 10% citronella extract with 47.22% growth inhibition of C. gloeosporioides and an average colony diameter of 3.150 cm after 15 days of incubation. The results of the in vivo test, showed significantly different results (á = 0.5%) between papaya fruit soaked with 10% citronella extract and controls, both in the incidence and spread of the disease. The spread of disease in treated papaya fruit was 13.72% while control papaya fruit reached 68.49% at 6 days of storage. Citronella extract with a concentration of 10% can extend the selling time of Calinna papaya (80% maturity index) 6 days longer than the control.

The creation of new superior rice varieties with high productivity and short-lived is necessary to support food security. The rice varieties produced must also meet people’s preferences, in this case have a rice taste that is preferred by the people of South Kalimantan. The purpose of study was to determine differences in content of amylose and amylopectin of rice grains between the genetic material, which consists of mutant lines of M3 and five parents of local varieties of South Kalimantan. The experiment used a randomized block design with two replications, the genetic material as single faktor, used being five local varieties of South Kalimantan and 25 M3 mutants derived from each parent’s mutation. The data was analyzed of variants with the F test at the level of α=5%, then continued the Scott-Knott test at α=5%. The results showed that content of amylose and amylopectin of grain of M3 lines significantly different with each parent. The results showed that the amylose and amylopectin content of rice grains from 30 genetic materials was significantly different. The results of the analysis of the grouping of 25 mutant lines and five parent varieties based on the content of amylose and amylopectin were obtained by nine groups. There are seven groups that belong to the rice type of rice textured pera consisting of 19 M3 lines and five parents. There are two groups that belong to the pulen textured rice group consisting of six M3 lines.

WeRise is a rainfed specific technology (IRRI-JIRCAS-IAARD) that helps farmers to determine planting time according to rainfall distribution and specific variety. The research was conducted in West Nusa Tenggara (WNT) and Central Java at 2018, involving 15 farmers in each location. It compared planting time according to WeRise’s recommendation (1) and farmers’ practice (2), using the same variety, namely Inpari 41, which is a specific high yielding variety for rainfed. It was analyzed using the T test at the 5% level. The best WeRise’s recommendations in WNT was ± 1 December 2018, while farmers’ planting time was carried out on ± 15 November 2018. Meanwhile, in Central Java WeRise’s recommendations was same as the farmers, on ± 15 November 2018. However, testing was still carried out following the second / third alternative WeRise recommendation even though the yield prediction were lower (1 December 2018). The yield from WeRise treatment and farmer practices was not significantly different with an average yield of 5.01 t ha-1 for the WeRise treatment and 4.84 t ha-1 for farmer practice in Central Java and an average yield of 5.44 t ha-1 for the WeRise treatment and 5.65 t ha-1 for farmer practice in WNT. This means that in this initial validation WeRise had shown a fairly good performance with equivalent yield to farmers. However, it was suspected that Werise’s prediction in Central Java was still too low or 54% lower than the actual yield, while the prediction in NTB reaches 102%.
WeRise是一项降雨专用技术(IRRI-JIRCAS-IAARD)，可帮助农民根据降雨分布和特定品种确定种植时间。该研究于2018年在西努沙登加拉(WNT)和中爪哇进行，涉及每个地点的15名农民。它根据WeRise的建议(1)和农民的实践(2)比较了种植时间，使用相同的品种，即Inpari 41，这是一个特定的雨养高产品种。在5%的水平上使用T检验进行分析。WNT的最佳种植时间为2018年12月1日，而农民的种植时间为2018年11月15日。与此同时，在中爪哇，wiise的建议与2018年11月15日的农民相同。然而，尽管产量预测较低(2018年12月1日)，但仍按照WeRise推荐的第二/第三种替代方案进行了测试。WeRise处理和农民做法的产量无显著差异，中爪哇省WeRise处理的平均产量为5.01 t hm -1，农民做法的平均产量为4.84 t hm -1, WNT省WeRise处理的平均产量为5.44 t hm -1，农民做法的平均产量为5.65 t hm -1。这意味着在最初的验证中，WeRise表现出相当好的性能，对农民来说产量相当。然而，有人怀疑Werise在中爪哇的预测仍然太低，比实际产量低54%，而在NTB的预测达到102%。

Consortium biofertilizer containing Nitrogen (N) Fixing Bacteria and Phosphate (P) Solubilizing Bacteria may substitute inorganic fertilizer in vegetable production. A greenhouse experiment was conducted to evaluate the effect of some combinations and doses of consortium biofertilizer and NPK compound fertilizer on available N and P in the soil, fresh weight of caysim (Brassica chinensis L. var. parachinensis.), and their uptake by caisim shoots after grown in low fertility soil. The experimental design was a randomized block design consisting of seven combinations and doses of consortium biofertilizer and compound fertilizer; and three control treatments. All treatments were repeated three times. The results showed that the combination of the which combination treatment of inorganic fertilizer and biofertilizer had a significant effect on the fresh weight of caysim shoots, available P and N and P uptake after harvesting compared to the biofertilizer treatment alone or without fertilization. Several treatments of combined doses of biofertilizers and NPK compound fertilizer produced the same yield as NPK compound fertilizer alone. The application of 300 kg/ha of compound fertilizer combined with 3,75 L/ha of biofertilizer enabled to increase the yield up to 16% compared to NPK fertilizer alone. This experiment explained that inoculation of biofertilizers can reduce the dose of NPK fertilizer to maintain yield, available P residue in soil and P uptake

Rice Farming Technical Efficiency Using Certified Seeds in Indramayu Regency. Production inputs used in rice farming can affect crop yields. Yields can be increased through technical efficiency or production efficiency approaches. Technical efficiency is defined as an effort to increase the maximum output from the use of a certain number of inputs or technology. This study aims to analyze the technical efficiency and determinants of technical inefficiency in rice farming using certified seeds in Indramayu Regency. The data collected were in the form of production inputs and farmer characteristics from several farmers whose rice farming used certified seeds in Jatibarang, Bangodua, Widasari and Cikedung Districts with a total sample of 84 respondents. Technical efficiency and determinants of technical inefficiency were analyzed using the Stochastic Frontier Analysis (SFA) approach. The results of the analysis show that rice farming using certified seeds in Indramayu Regency is technically efficient with an average technical efficiency value of 0.93. Production inputs that affect technical efficiency include land, seeds, nitrogen nutrients, phosphate nutrients, potassium and pesticides. Land, seeds, phosphate and potassium nutrients significantly affect technical efficiency at the 1% real level, while nitrogen and pesticide nutrients have a significant effect on technical efficiency at the 5% real level. Variables that affect technical inefficiency include age and experience of farmers. Farmer’s age has an effect on technical inefficiency at the real level of 5%, while farmer’s experience has a significant effect on technical inefficiency at the real level of 10%. The conclusion is that rice farming using certified seeds in Indramayu Regency is technically efficient.

Lemongrass is the raw material for lemongrass oil production. Indonesia is one of the ten largest lemongrass oil producing countries in the world. Lemongrass oil industry will be generated large amount of lemongrass waste. The aim of this study was to determine the effect of elephant grass (Pennisetum purpureum) substitution with lemongrass waste on high forage feed on in vitro rumen fermentation. This study was arranged with randomized block design with 5 treatments (100R: 0% lemongrass waste, 75R: 25% lemongrass waste, 50R: 50% lemongrass waste, 25R: 75% lemongrass waste, and 0R: 100% lemongrass waste) and 4 different rumen collecting time as block. The results showed that the substitution of grass with lemongrass waste did not give a significant difference to dry matter content, but it could reduce protein content and increase crude fiber and crude fat significantly (P <0.05). The results of the in vitro analysis showed that lemongrass substitution did not affect pH, gas production rate, butyric acid, valeric acid, iso-butyric acid, and iso-valeric acid both in terms of quantity and proportion. The used of lemongrass by 25% (75R) was not affected on organic matter, potential gas production and methane production (24 hours) but decreased protein content and increased lag time significantly (p <0.05). The used of lemongrass by 50% was significantly reduce methane gas production (P <0.05). The increased of lemongrass waste concentration was affected partial VFA profile by decreasing in the amount of acetic acid. A significant decreased in the A/P ratio occurred in the used of lemongrass by 100%. Lemongrass waste could be used as elephant grass substituted up to 25% in high-forage feed without decreasing potential gas production, digestibility, and partial total VFA.

In vitro propagation of pitcher plants is still limited only using seeds, while the other in vitro methods using leaf explants such as embryogenesis, organogenesis, and callus culture has not been widely reported. The research aims to study the growth response of leaf explants in two species of pitcher plants (Nepenthes gracilis and Nepenthes reinwardtiana), which formed callus in several treatment media combinations. Leaf pieces were taken from a 4-month pitcher plant culture were grown on the treatment media, namely modified media of Murashige & Skoog with a half concentration (½ MS) added 2.4-Dichlorophenoxoxyacetate (2.4-D) with a concentration of 0, 0.5, 1, 1.5, and 2 mg L-1 and kinetin (0.5 mg L-1). The treatment was then stored in a dark environment to induce callus formation. The observation for 12 weeks showed that the time of callus formation in two species of pitcher plant observed was not significantly different. Both species of pitcher plants begin to form callus in the fourth week after treatment. None of the leaf explants were planted on the control medium without hormones formed callus. The best medium for callus induction in N. gracilis is ½ MS medium added with 2 mg L-1 2,4-D and 0.5 mg L-1 kinetin, with callus morphology brownish-white with friable texture. In comparison, the optimum callus media from leaf explant of N. reinwardtiana has not been obtained yet. Thus further research is still needed.

This research was conducted to: 1) analyze the contribution of female worker income to household income, and 2) analyze the factors that influence the female worker income of plantation female workers at P.T. Agro Muko (Mukomuko Estate). The number of female workers at P.T. Agro Muko (Mukomuko Estate) was 297. Therefore, by using the Slovin formula, the counted number respondents was 75. The contribution of female worker’s income to household income was counted with the percentage of female worker’s income contribution to the total of household income. Meanwhile, the factors that influenced to the income of female worker was analyzed using multiple linear regression model. The results indicate that the average income of female worker is Rp 1,481,680/month with an average contribution of 55.17% to household income. Female worker ages and husband’s income had negative effect on the female worker income, while formal education, number of family dependents, and working experience had positive effect. Other family member’s income had no effect.
