Pelatihan Pembuatan Pakan Ikan dan Pupuk Organik Berbahan Aktif Mikrob bagi Kelompok Tani Desa Nagrak dan Aplikasinya

Abstract

The Jabar 7 farmers’ group in Nagrak Village, Salawu Subdistrict, Tasikmalaya Regency consists of vegetable farmers, livestock keepers such as chicken and duck farmers, and freshwater fish cultivators. The problems they face include rising prices of livestock feed, fish pellets, and NPK fertilizer. Through the 2025 Dosen Pulang Kampung Program, a community service activity was conducted involving 30 participants who were members of the farmers’ group from Nagrak Village and the surrounding area. This program aimed to provide training to the farmers on producing probiotic-based fish feed and organic fertilizer using microbial starter cultures made from village-available materials, such as household waste for breeding black soldier fly (BSF) or maggots. The methods implemented included face-to-face delivery of instructional materials, beginning with a pre-test and ending with a post-test, followed by hands-on practice with lecturers and students, field practice with participants, application of the practice results by the trainees, and monitoring conducted two months after implementation. Evaluation of the pre-test and post-test results at the beginning of the training used a one-group pre-test–post-test design with the normalized gain (N-gain) analysis method. The classroom instruction resulted in a 19.2% increase in participants’ understanding of the material. After two months of application, interviews and field observations indicated that the use of probiotic fish feed improved fish health, fermented household waste used as maggot feed produced more abundant and larger maggots, and, when fed to chickens, the maggots accelerated egg production.
