Abstract

Rice is one of the leading commodities for Baureno District, Bojonegoro Regency. Along with high revenue potential, farmers working in this area also have to face various agricultural risks. This study aims to analyze the production risk and income risk of rice farming. The study was conducted in Baureno District, Bojonegoro Regency, involving 55 farmers as respondents who were selected by simple random sampling. The level of production risk and farm income is calculated by the coefficient of variation analysis. The results of this study showed that rice farming in Baureno sub-district has high production risk and income risk, as indicated by the analysis of the coefficient of variation on production risk of 0.584 and income risk of 0.626.Keywords: Production risk, income, rice

Abstract

Empowering housewives through the strengthening of local resource–based food processing skills is a strategic approach to enhancing food security while simultaneously promoting household economic self-reliance. This community service program aimed to enhance the knowledge capacity, technical skills, and entrepreneurial orientation of housewives through innovation in soybean processing into soy milk with various flavour. The program involved 35 housewives residing in Jolosutro, Srimulyo Village, Bantul Regency, and was implemented using a Participatory Rural Appraisal (PRA) approach. The implementation methods included participatory discussions, extension activities, hands-on processing training, and assistance in the development of home-based enterprises. The results indicate an improvement in participants’ understanding of the nutritional value of soybeans and the importance of food diversification, as well as enhanced technical skills in the hygienic production of soy milk. Furthermore, product innovation emerged through the development of various flavour, accompanied by increased interest among participants in developing soy milk as a home-based enterprise. Overall, this community service activity contributes significantly to strengthening community capacity through the sustainable utilization of local resources.

Abstract

Xanthomonas oryzae pv. oryzae (Xoo) merupakan bakteri patogen yang menyerang padi dan sulit dikendalikan. Pengendalian hayati kitosan telah banyak dikembangkan dan lebih efektif dalam nanopartikel. Beberapa penelitian yang sudah dilakukan menunjukkan konsentrasi nanopartikel kitosan sebagai antibakteri terhadap Xoo bervariasi. Penelitian ini bertujuan untuk mengetahui konsentrasi optimal nanopartikel kitosan sebagai antibakteri terhadap Xoo secara in vitro. Penelitian dilakukan optimasi nanopartikel pertama konsentrasi 0,06%; 0,07%; 0,08%; 0,09%; 0,1%. Konsentrasi optimal dioptimasi kedua, kemudian konsentrasi paling optimal dioptimasi ketiga dengan kenaikan 0,005%. Satu mL suspensi Xoo dicampurkan merata dalam 100 mL medium PSA kemudian dituang dalam 5 petri. Paper disc steril diameter 7 mm ditetesi 0,1 mL akuades steril (kontrol 1), asam asetat 1% (kontrol 2), kitosan (CN) di optimasi pertama, dan nanopartikel kitosan (CNP) secara terpisah dan setelah kering diletakkan di medium PSA. Diameter zona hambat (pada jarak cm dari paper disc) diukur pada hari ke-2, 4, 6 setelah perlakuan. Optimasi dilakukan sebanyak 3x. Data dianalisis menggunakan variansi ANOVA aras 0,05. Hasil penelitian menunjukkan konsentrasi nanopartikel kitosan 0,06% dan 0,08% lebih optimal pada optimasi pertama. Optimasi kedua menunjukkan konsentrasi 0.06% lebih baik dibandingkan 0,08% meskipun tidak berbeda signifikan. Kenaikan konsentrasi 0,005 pada optimasi ketiga tidak menunjukkan perbedaan signifikan terhadap kemampuan antibakterinya.Kata kunci: antibakteri, kitosan nanopartikel, optimasi, Xoo
