Abstract

The biofloc system catfish wastewater is in the form of accumulation of organic residues from feed residues, catfish manure, feed particles and bacteria and algae, because the biofloc catfish cultivation wastewater can be processed into organic fertilizer especially liquid organic fertilizer. The study used a completely randomized single factor treatment with an aerobic (A) fermentation process and Anaerobic fermentation process (B). Each treatment was repeated 8 times to obtain 16 experimental units. Furthermore, the results of the study data were analyzed by variance at the level of 5 percent. The results showed that the growth rate of catfish was very good. Where growth continues to increase the 10th day observation until the end of the study. While the content of N, P and K in the POC produced did not show a significant difference between POC fermented by Aerob and Anaerob. POC content fermented by Aerob; N = 1.645, P = 0.326 and K = 1.143 while Anaerobic fermentation; N = 2.189, P = 0.278 and K = 1.165.
ANALISIS FILTER BIOLOGI CACING SUTRA (Tubifex sp.) DENGAN LUAS WADAH YANG BERBEDA TERHADAP PERTUMBUHAN DAN KUALITAS AIR IKAN LELE SANGKURIANG (Clarias gariepinus) Arie Perdian Asmito; Suharun Martudi; Dedi Pardiansyah; Nasir Ahmad

Abstract

The use of biological filters for silkworms (Tubifex sp.) With different container areas for growth and improvement of water quality in the cultivation of Sangkuriang catfish (Clarias gariepinus). The research objective was to determine the best level of silk worm container in utilizing catfish culture waste to improve the water quality of sangkuriang catfish (Clarias gariepinus) culture and to see the growth rate of catfish. The design used was a completely randomized design with 3 treatments and 4 replications. Treatment P1: Catfish cultivation with 1 silk worm cultivation level, P2: Catfish cultivation with 2 silk worm cultivation levels, and P3: Catfish cultivation with 3 silk worm cultivation levels, and each like catfish cultivation with a stocking density of 75 fish / m2. The results of this study indicate that the best treatment on P3, (13,412.83) is significantly different from P2 (11.234.70) and P1 (11.400.87), and has a significant effect on absolute length, absolute weight, and conversion, but has no effect. Significant to the average survival of treatment P1 (92.00), P2 (96.33) and P3 (98.33), and the best catfish water quality was in treatment (P3) with three levels of silk worms. Utilization of catfish culture waste to the growth of individual numbers and biomass weight of silkworms (Tubifex sp.), The number of individuals, namely 76.88 thousand m2 and biomass weight of 0.208 kg

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penyiponan 0%, 15%, 30%, 45%, dan 60% untuk pertumbuhan ikan lele sangkuriang (Clarias gariepinus) pada sistem bioflok. Penelitian dilaksanakan pada bulan April sampai 12 Juni 2016, yang berlokasi di Jl Bukit Barisan Kelurahan Tengah Padang Kecamatan Teluk Segara Kota Bengkulu. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Perlakuan penyiponan bioflok yang digunakan sebagai berikut : P1= penyiponan bioflok 0%, P2 = penyiponan bioflok 15%, P3 = penyiponan bioflok 35%, P4 = penyiponan bioflok 45% , P5 = penyiponan bioflok 60%. Untuk melihat perbedaan tersebut dilakukan uji BNT. Penyiponan yang berbeda terhadap pertumbuhan ikan lele sangkuriang (Calias gariepenus) pada sistem bioflok berpengaruh sangat nyata terhadap pertumbuhan berat, pertumbuhan panjang, konversi pakan, efisiensi pakan dan kelangsungan hidup ikan lele sangkuriang. Penyiponan terbaik terhadap pertumbuhan ikan lele sangkuriang adalah perlakuan P4 (penyiponan bioflok 45%)

Abstract

This study aims to determine the prevalence and degree of ectoparasite infection in sand lobster (Panulirus homarus) in different Tank in Bengkulu City. This study was conducted in October – November 2021 in Bengkulu City for 57 days. The method used in this study is a survey method by taking samples from a population that is being observed. Determination of the sampling location was carried out by purposive sampling method at 3 (three) locations of storage/suppliers of sand lobster in Bengkulu City. Ana Lidiana's Tank has the highest prevalence rate of 62.50%, the prevalence rate category is often.
