Abstract

Scads (Decapterus spp.) is one of the main catches of fishermen in Kubutambahan Village caught using slerek. The catch is sold to collectors and retailers. This study aims to assess the marketing flow and marketing efficiency level of kite fish in Kubutambahan Village. This research was conducted from February 2024 to July 2024. The research method used was descriptive quantitative and qualitative methods by conducting observations and interviews at marketing institutions. Based on observations and interviews, two marketing channels were found, the first one, namely kite fish from fishermen will be sold to retailers, and ends at consumers, and the second one, kite fish from fishermen to intermediary traders then to retailers and ends at consumers. The value of marketing margins and marketing costs in marketing channel I is IDR 5,042/kg, and IDR 1,917/kg. The value of marketing margins and costs in marketing channel II is IDR 9,956,-/kg, and IDR 2,168,-/kg. The value of fisherman's share in channel I is 75%, and the value of fisherman's share in marketing channel II is 57.29%. The level of efficiency of kite fish marketing or the percentage of total margin on marketing channel I after calculation is 25%, and the level of efficiency of fish marketing on marketing channel II is 43%, this figure shows that kite fish marketing using marketing channel I is still classified as efficient, and marketing channel II is classified as less efficient, if the percentage of total margin is 0 - 33%, and is said to be less efficient at 34-67% and efficiency is said to be inefficient at 68-100%.

Abstract

This study aims to determine the effect of giving vitamin E with different doses in feed on the reproductive condition of female jatimbulan tilapia (Oreochromis niloticus) carried out at the Technical Implementation Unit (UPTD) Freshwater Aquaculture Denpasar Bali. The method used in this study was experimental, using 4 different treatments, namely treatment A (control), treatment B (vitamin E 100 mg/kg), treatment C (vitamin E 150 mg/kg), and treatment D (vitamin E 200 mg/kg) with 3 repetitions. Data were analyzed using One Way ANOVA test, then continued with Duncan's further test using Statistical Package for the Social Sciences (SPSS) software with 95% confidence level (α = 0.05). The total samples observed in this study were 12 female jatimbulan tilapia gonads. The results showed that the provision of vitamin E at a dose of 200 mg/kg feed is the best dose for tilapia gonad maturation, this is because the level of gonad maturity can develop up to TKG V. As well as the value of IKG, fecundity, and fecundity. As well as the value of IKG, fecundity and oocyte diameter are at the optimal amount.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh perbedaan kom posisi dasar terhadap kualitas air dan pertumbuhan ikan nila (Oreochromis niloticus). Penelitian ini dilakukan pada bulan November 2024. Metode yang digunakan adalah metode eksperimental dengan rancangan acak lengkap sebanyak 3 perlakuan dan 3 ulangan. Setiap perlakuan diberikan media filter yang berbeda yaitu perlakuan A (bio column)(kontrol), perlakuan B (bata), dan perlakuan C (bata + abu dasar genteng 10%). Hasil penelitian menunjukkan bahwa komposisi dasar filter memiliki pengaruh terhadap pengurangan amonia. Konsentrasi rata-rata amonia perlakuan A sebesar 0,979 mg/L; perlakuan B sebesar 1,078 mg/L; dan perlakuan C sebesar 0,779 mg/L. Suhu berkisar 27,5-27,6°C, oksigen terlarut berkisar 6,4-6,5 mg/L, pH berkisar 7,72-7,94, nitrit berkisar 0,010-0,011 mg/L, dan nitrat berkisar 0,548-0,560 mg/L. Hasil penelitian menunjukkan pengaruh tidak berbeda nyata (P>0,05) terhadap pertumbuhan, SGR, FCR, dan SR ikan nila. Rata-rata nilai berat mutlak perlakuan A sebesar 9,26 g, perlakuan B sebesar 8,17g, dan perlakuan C sebesar 7,72 g. Nilai SR diperoleh pada perlakuan A, B, dan C berurutan 86,7%; 86,7%; dan 93,3%.
