Abstract

Brown planthopper (Nilaparvata lugens Stål) population from Klaten and Yogyakarta may develop into new biotype, but research on the genetic aspect of these populations is limited.  Random amplified polymorphic DNA (RAPD)-PCR technique was used to identify the genetic similarity of brown planthopper population from Klaten and Yogyakarta compared to the population of nearby region. Brown planthopper were collected from paddy field in Klaten, Yogyakarta, Sukoharjo, Boyolali, Karanganyar, Sragen, and Ngawi. Five random primers, namely OPB 01, OPB 07, OPC 04, OPC 08, and OPN 15 were used to amplify the brown planthopper. The present study revealed that five random primers produced DNA band patterns clearly and comparable. However, no primer produced DNA band that could differentiate the brown planthopper population from Klaten and Yogyakarta compare to the population from nearby region. Based on dendrogram, the population from Klaten and Yogyakarta showed a genetic similarity to the nearby population from Sukoharjo, Boyolali and Sragen, except from Karanganyar and Ngawi. Intra-population genetic studies of brown planthopper from Klaten and Yogyakarta may be needed to reveal more genetic characters.

Abstract

The application of fertilization and giving organic matter of different causes differences in soil fertility status, with the availability of macro nutrients on a farm, then to know the action proper fertilization. The purpose of this study is to determine the dose fertilization fertility status of the local potential. The research was conducted using a survey method, ie by observing and sampling the soil directly in the field, followed by laboratory analysis to determine the chemical content of the soil. The results showed the level of soil fertility in Wonogiri low fertilizer needs are different in each district in Wonogiri. Areas with low nutrient availability will provide a high dose of fertilizer, and conversely a low fertilization results indicate the availability of nutrient elements in the soil are sufficient for plant growth, although it should still be nurtured to backup next season.

Abstract

Soybean is one of the most important food commodities in Indonesia and also it has high value. The needs continue to increase each year, but not offset by increased production become an issue that must be addressed. One attempt to increase soybean production is through the cultivation in agroforestry systems through improving the quality of soil fertility. This research aims to study the effect of various doses of litter teak and NPK fertilizer on chemical soil fertility and the potential of soybeans yield in agroforestry systems based teak crops. Experiments using a Randomized Complete Block Design (RCBD) with two factors, namely litter teak doses (0 ton ha-1, 2.500 ton ha-1, 5.000 ton ha-1, 7.500 ton ha-1) and doses of NPK fertilizer (60-60-60 and 60-120-60) on Grobogan soybean varieties. The variables measured were pH, organic matter content, N-total soil, cation exchange capacity (CEC), plant tissue of N, P-total soil, and component production. Data analysis using analysis of variance F-test based on the level of 5% and significantly different variables followed by Tukey’s method level of 5%. The results showed that combination treatment with various doses of teak litter NPK fertilizers can increase total nitrogen content of the soil with the highest yield of 1.69% on S1D2 treatment, but to organic matter, CEC, pH, and total soil P not significant effect. Component of soybean varieties of the highest Grobogan of 0.83 tons ha-1 in the treatment S1D1. The result was still below the average of the national soybean production.

Abstract

Potential of Maggot (Black Soldier Fly) as Animal Feed in Miri Village Kismantoro Wonogiri. Cultivation of chicken and catfish was a field of business that was mostly carried out by residents of Miri Village, Kismantoro District, Wonogiri Regency. The high component of feed costs results in low profits. So far, farmers still rely on pellets as the main feed for their livestock. Alternative feeds in the form of Black Soldier Fly (BSF) larvae or maggot were well known to residents, but only a few residents had ever used maggot as feed. Residents had never received education and training on maggot cultivation. This activity aims to increase the knowledge and skills of Miri Village residents in maggot cultivation, the dependence of farmers on artificial feed can be reduced and replaced with feed from maggot cultivation. Activities carried out in the service consist of socialization and training on maggot cultivation. The socialization was in the form of exposure to the benefits and propagation of maggots, while the training materials were the practice of catching eggs, maintaining maggots, and harvesting maggots. The results of the activity showed an increase in participants' knowledge regarding maggot cultivation by 21.32%. The participants also showed interest in carrying out practical activities. The benefits of BSF cultivation include reducing household waste, producing maggots as animal feed, and producing organic fertilizer.
