Abstract

Integration of simple biotechnology practice into conventional feed manufacturing methods is expected to improve the quality of artificial feed. Fermentation technology can be used as an alternative way toincrease digestibility or bioavailability of artificial feed. The fermentation agent used is the starter of Lactic Acid Bacteria (LAB), Saccharomyces cerevisiae (Sc) and Rhizopus oligosporus (Ro). This experiment used Completely Randomized Design (CRD) with four treatments (F1; withoutfermentation agents, F2; BAL, F3; Sc and F4; Ro) and three replications so that the total experimental units were 12 experimental units. The variables measured included the physical and chemical quality of feed, the level of feed consumption and the growth parameters of tilapia. Fermented feed produced significant fish growth (P <0.05) even with the same feed consumption level compared with the control. Breakdown of the nutrient content as a result of the fermentation process causes a far more efficient utilization.

Abstract

Aquaponic refers to any system that combines conventional aquaculture with hydroponics in a symbiotic environment. In this study, catfish was cultured with green cabbage. The aim of this study was to observe catfish growth in aquaponics system. The growth parameters measured included feed consumption (g/day/fish), growth (g), growth rate (%/day), mean metabolic body weight (kg0.8), metabolic feed intake (g/ kg0.8/day), relative growth rate per metabolic weight (g/kg0.8/day), relative feeding rate (%BW/day), relative feeding rate per metabolic weight (g/kg0.8) and feed conversion. Factorial randomized trial was used with two factors namely fish stocking density (P) and plant substrate composition (S) with three replications. Stocking density factor consisted of two treatments which were 75-125 individuals per m2 (P1) and 126-175 individuals per m2 (P2). The composition of the substrate included two treatments, namely S1 (70% gravel+30% palm fibres) and S2 (70% pumice+30% palm fibres). The data shown that there is no significant difference of substrate and interaction (stocking density x substrate) factors to the growth of catfish (P>0.05). Whereas, for the treatment of stocking densities, a significant difference (P <0.05) was found on four growth parameters (initial weight, SGR, RGRm and feed consumption).Keywords : aquaponics, catfish, green cabbage and fish growth

Abstract

Penelitian ini dilatarbelakangi oleh pentingnya pengelolaan rantai pasok lobster batik di UPT. Pelabuhan Perikanan Pantai (PPP) Tenau Kupang untuk meningkatkan efisiensi dan keuntunganpemasaran. Tujuan penelitian adalah menganalisis manajemen rantai pasok lobster batik, termasuk pemetaan aliran rantai pasok, perhitungan biaya pemasaran, margin pemasaran, dan efisiensi pemasaran. Metode yang digunakan adalah non probability Sampling dengan teknik sampel jenuh, serta pengumpulan data melalui kuesioner dan wawancara. Data yang diperoleh dianalisis melalui tujuh tahapan pemetaan rantai pasok, meliputi aktor, proses, arus produk dan informasi, volume produk,hubungan antar aktor, dan tata kelola. Hasil penelitian menunjukkan gambaran komprehensif mengenai struktur dan dinamika rantai pasok lobster batik di PPP Tenau Kupang, serta memberikan estimasi biaya dan margin pemasaran yang relevan. Kesimpulan menegaskan perlunya pengelolaan rantai pasok yangterintegrasi untuk meningkatkan efisiensi dan keuntungan pemasaran lobster batik. Implikasi hasil penelitian ini mendorong perlunya studi lanjutan untuk memperdalam pemahaman rantai pasok, biaya, dan margin pemasaran lobster batik di pelabuhan perikanan lain guna mendukung pengambilan keputusan yang lebih baik.
