Processing Rice Land to Increase Rice Food Security in Semarang City: (Location study Purwosari Village)
No full textThis research aims to understand the influence of five production factors, namely land area, urea fertilizer, NPK fertilizer, labor, and pesticides, on the amount of rice production in Purwosari Village, Semarang. The method used is a case study involving 61 rice farmers in the village. Data analysis was carried out using the Cobb-Douglas production function, production scale, and economic efficiency. The research results show that all production factors together have a very significant influence on the amount of rice production. However, when analyzed individually, only land area, urea fertilizer, and NPK fertilizer had a significant effect. Labor and pesticides did not show a significant effect on rice production. The scale of rice production in Purwosari shows an increasing trend. The economic efficiency of using production factors shows that the use of land, urea fertilizer, and NPK fertilizer has not reached optimal levels (NPM/BKM >1). On the other hand, the use of labor and pesticides is classified as inefficient (NPM/BKM <1). In conclusion, this research recommends increasing land use, urea fertilizer, and NPK fertilizer to increase rice production in Purwosari. On the other hand, the use of labor and pesticides needs to be optimized to achieve better efficiency

Efektivitas Tepung Daun Mangrove untuk Mengendalikan Penyakit Vibriosis pada Larva Udang Vaname (Litopenaeus vannamei)
No full textShrimp production in several Asian countries, including Indonesia, accounts for more than 85% of world production, thus control of shrimp larval diseases must be strengthened to increase production. This study aimed to test the effectiveness of mangrove leaves, Rhizopora sp, in controlling larval vibriosis of the vannamei shrimp (Litopenaeus vannamei). The study began with in vitro tests to evaluate the antimicrobial activity of mangrove leaf flour against Vibrio sp bacteria at doses of 400, 500, 600, 700, 800, 900, 1000 mg/L, 5% amoxicillin antibiotic (K+) and without mangrove flour (K). In the in vivo test, vannamei shrimp larvae (mysis-3) were immersed in a solution containing mangrove leaf flour with the three best doses of in vitro test results; 800, 900, and 1000 mg/L water, plus K-, for 15 minutes according to the treatment dose and maintained for 8 days before being challenged with Vibrio spp. The parameters observed were total hemocyte count (THC), differential hemocyte count (DHC), and survival rate (SR), which were observed on days 1 and 8, respectively, with the SR parameter observed on day 7 following the challenge test. The results showed that the Mangrove leaf diet at 800 and 900 mg/L significantly improved larval resistance to the pathogen V. harveyi (P < 0.05). The high resistance was triggered by THC immunological response and the high proportion of semi-granular and hyaline at doses of 800 and 900 mg/L (P<0.05). Mangrove leaf powder can therefore suppress vibriosis disease in vanamei shrimp larvae using the immersion method at 800 and 900 mg/L concentrations.Produksi udang di beberapa negara di Asia termasuk Indonesia merupakan penyumbang >85% produksi global, oleh karena itu pengendalian penyakit larva udang dalam rangka peningkatan produksi perlu ditingkatkan. Penelitian ini bertujuan untuk menguji efektivitas daun mangrove, Rhizopora sp untuk mengendalikan penyakit vibriosis pada larva udang vaname (Litopenaeus vannamei). Penelitian diawali dengan uji in vitro untuk mengevaluasi aktivitas antimikroba tepung daun mangrove terhadap bakteri Vibrio sp dengan dosis 400, 500, 600, 700, 800, 900, 1000 mg/L, antibiotik amoksilin 5% (K+) dan tanpa tepung mangrove (K). Pada uji in vivo, larva udang vanamei (mysis-3) direndam pada larutan mengandung tepung daun mangrove dengan 3 dosis terbaik hasil uji in vitro yaitu 800, 900, 1000 mg/L air, ditambah K-, selama 15 menit sesuai dosis perlakuan dan dipelihara selama 8 hari dan di uji tantang dengan Vibrio sp. Parameter yang diamati adalah Total haemocyte count (THC), Differential haemocyte count (DHC) dan Survival rate (SR), diamati pada hari ke-1 dan 8, sedangkan parameter SR diamati pada hari ke-7 pasca uji tantang. Hasil penelitian menunjukkan bahwa tepung daun mangrove dapat meningkatkan resistensi larva terhadap penyakit patogen V. harveyi dengan dosis terbaik 800 dan 900 mg/L (P?0,05). Tingginya resistensi ini diinisiasi oleh respon imun THC dan DHC khususnya persentase semi granular dan hyalin yang tinggi pada dosis 800 dan 900 mg/L (P?0,05). Dengan demikian maka tepung daun mangrove dapat digunakan untuk mengendalikan penyakit vibriosis pada larva udang vaname melalui metode perendaman dengan dosis 800 dan 900 mg/L
