Abstract

Feed is one of the most determining factors in cultivation activities, with good and correct feed making techniques it is expected to create fish feed with a formulation that is in accordance with the growth of catfish. The purpose of this community service is to improve the knowledge, attitudes and skills of fish farmers. The method of implementing the activity is through practice, discussion and question and answer. The results of the community service activities went well and correctly, participants were able to understand the material presented by the resource person including feed formulation, material selection and fish feed printing. The tools and materials used in this activity are feed printing machines (vertical and extruder) and scales. While the materials used are 25% fish meal, 22% soybean meal, 40% bran, 10% tapioca, 2% vitamins, 1% minerals

Abstract. Suryani SAMP, Sudiarta IG, Darmadi NM, Edi DGS, Sudiarta IK, Pratama GAS, Janaguna IMA, Sugiana IP. 2025. Ecological diagnosis of Lake Batur (Bali, Indonesia) post-disturbance using multimetric phytoplankton indices. Biodiversitas 26: 4982-4990. Plankton communities are rapid responders to environmental change and serve as sensitive indicators of ecological stress in tropical volcanic lakes. In July 2025, Lake Batur (Bali, Indonesia) experienced a major fish mortality linked to hypolimnetic upwelling and nutrient enrichment from aquaculture. To assess post-disturbance conditions, we sampled three sites with varying aquaculture intensity—Seked (low), Buahan (moderate), and Trunyan (high, mortality epicenter)—one week after the event. Field measurements included temperature, pH, dissolved oxygen, conductivity, redox potential, nutrients, and sulfide, while phytoplankton analysis covered diversity (Shannon–Wiener), evenness (Pielou), dominance (Simpson), and saprobity (Dahuri). Results revealed clear spatial contrasts. Trunyan showed the strongest stress signals, with oxygen depletion, negative redox potential, and elevated ammonia, while Seked and Buahan displayed milder alterations. In total, 23 phytoplankton genera were identified, dominated by diatoms such as Ulnaria and Actinotaenium. Trunyan exhibited reduced richness, lower diversity (H’ = 1.84), and higher dominance (D = 0.27), indicating a shift toward opportunistic taxa. Saprobity values showed a gradient of organic pollution, increasing from Seked (1.5) to Trunyan (2.0), consistent with aquaculture intensity. These findings highlight the value of integrating multimetric plankton indices with physicochemical data to distinguish natural upwelling effects from anthropogenic nutrient loading. While diatom persistence suggests some resilience, recovery of sensitive taxa depends on reducing nutrient inputs and regulating aquaculture. This integrative framework offers a practical diagnostic tool for adaptive lake management and contributes to achieving clean water, climate action, and aquatic biodiversity goals.

Abstract

Kegiatan Pengabdian bertujuan untuk meningkatkan nilai ekonomi ikan lele. Kegiatan dilaksanakan di Desa Peguyangan Kaja, Denpasar, dengan sasaran kelompok usaha mikro yang bergerak di bidang pengolahan pangan. Permasalahan yang diidentifikasi adalah belum mampu mencari solusi untuk ikan lele dengan berat berlebih, keterbatasan pengetahuan dalam pengolahan lele, Oleh karena itu, pengabdi memperkenalkan teknologi tepat guna dalam pengolahan lele menjadi abon. Kebaruan di dapat Mitra adalah Pembuatan Abon yang belum pernah dibuat, Mampu membuat Abon Lele Yang berukuran besar yang secara umum kurang disukai, selain itu menggunakan Spiner untuk menghilangkan Kadar minyak berlebih, serta dalam Pembuatannya menerapkan Prinsip GMP dan SSOP. Kegiatan diawali dengan sosialisasi, pendampingan teknis Pembuatan Abon, Pengemasan dan Pelabelan. Hasil kegiatan menunjukkan peningkatan kemampuan mitra dalam mengolah ikan lele menjadi produk abon yang berkualitas. Dampak dari kegiatan ini adalah peningkatan Kemampuan Mitra untuk diversifikasi produk olahan ikan, Menambah Sumber Penghasilan, Program ini juga diharapkan dapat berkelanjutan.
