Abstract

Pakan merupakan salah satu faktor utama yang harus diperhatikan mengingat dalam kurun waktu produksi, kontribusi pakan dapat mencapai 60% dari total biaya produksi. Dengan meningkatnya harga bahan baku pakan akan menyebabkan biaya produksi meningkat hal ini dapat menurunkan tingkat keuntungan bagi petani ikan. Sehubungan dengan hal tersebut maka telah dilakukan alih teknologi untuk memberikan pemahaman dan ketrampilan kepada petani ikan di Desa Pasir kulon Kecamatan Karang lewas untuk memproduksi pellet organik dengan bahan baku tanaman eceng gondok dan cacing tanah. Pendekatan metode yang dilakukan dalam kegiatan ini menggunakan metode PRA (Partisipatory Rural Appraisal) yang meliputi pembekalan teori, praktek, demonstrasi plot dan selanjutnya dilakukan monitoring dan evaluasi. Proses produksi dimulai dengan pemilihan bahan baku yang berkualitas, penyusunan komponen bahan baku sesuai jenis ikan yang dituju, penghitungan kebutuhan bahan baku yang akan digunakan, pembuatan pellet. Hasil evaluasi teori dan ketrampilan peserta kegiatan menunjukkan adanya peningkatan pemahaman dan ketrampilan peserta (petani ikan) terhadap kemampuan dalam melakukan produksi pakan buatan sendiri. Hasil evaluasi dampak menunjukkan adanya perubahan perilaku dan pola pikir peserta. Kata kunci : pellet organik, eceng gondok, cacing tanah. AbstractFeed is one of the main factors that must be considered considering that in the production period, the contribution of feed can reach 60% of the total production cost. Increasing the price of feed raw materials will cause increased production costs, this can reduce the level of profit for fish farmers. In connection with this matter, transfer of technology has been carried out to provide understanding and skills to fish farmers in Pasir Kulon Village, Karang Lewas District to produce organic pellets with raw materials for water hyacinth and earthworms. The method approach taken in this activity uses the PRA (Participatory Rural Appraisal) method which includes provisioning theory, practice, demonstration plots and subsequently monitoring and evaluation. The production process begins with the selection of quality raw materials, preparation of components of raw materials according to the intended fish species, calculation of raw material requirements to be used, pellet making, and packaging, and also application to cultured fish. The results of the evaluation of the theory and skills of the activity participants showed an increase in the understanding and skills of the participants (fish farmers) on the ability to produce homemade food. The results of the impact evaluation indicate changes in the behavior and mindset of the participants. Keywords: organic pellets, water hyacinth, earthworms.

Abstract

Mineralization in the Bukit Randu area and its surroundings is formed by geological structures to be investigated.This study uses data on fault striation, quartz vein plane and quartz veinlet plane. This study aims to determine the main structural pattern forming the mineralization zone. This research is useful for determining the geological structure model in the Randu Hill area. The research method was carried out through data collection in the field and analysis in the laboratory. Field data collection includes striation data measurement, quartz vein plane measurement, quartz veinlet plane and quartz vein sampling. Laboratory analysis includes stereographic analysis of striation and rose diagram analysis of vein and veinlet measurement data, and vein polishing mineragraphy. Quartz vein and veinlet mineralization in the Randu Hill area is controlled by a right lateral strike-slip fault trending northwest-southeast and a north-south normal fault. This mineralized zone is a north-south trending transtension zone due to en-enchelon right stepping of right lateral strike-slip fault. Precious metal minerals are located in the north-south trending veins in the same direction as the regional compression stress and normal faults.
