Abstract

Citric acid is a weak organic acid found in citrus fruits and leaves with many benefits. This study aimed to examine the effect of citric acid in feed on the leaching of heavy metal mercury (Hg) from the body of the catfish (Pangasianodon hypophthalmus). This research was conducted in a semi-indoor room. The research design used a completely randomized design (CRD) with 4 (four) treatments and 2 (two) replications. Treatment A (0.0 gram/kg), B (1.0 gram/kg), C (2.0 gram/kg) and D (3.0 gram/kg). The test fish were catfish with a weight of ±266.03 grams/head. Catfish obtained from the Batanghari river taken from cultivators in Sebubuk Village, Muaro Jambi, immediately the Hg levels in catfish meat ranged from 0.000021- 0.000038 µg/gram in waters that had Hg levels of 0.00018 µg/ml. Then the fish were kept in a concrete tank measuring 70x40x35 cm as many as 8 units with a volume of 200 liters of water. The test feed was given satisfactorily three times a day. The results of observations of citric acid feeding for 40 days showed that the Hg of early catfish meat on the back g/gram 0.000035 µg/gram was higher than in the stomach 0.000032 µg/gram and tail 0.000020 µg/gram. The results of the analysis between treatments of fish meat Hg were significantly different and there was a decrease in Hg levels, for treatment A 0.000032 to 0.000025, B 0.000031 to 0.000024, C 0.000030 to 0.000022 and D 0.000029 to 0.000020 µg/gram. The average decrease in Hg of meat was 0.00000305 to 0.00000228 µg/gram. The best average survival rate of catfish in treatment D (100%) and the lowest A (75%).

Abstract

Abstract. The high level feed of consumption of catfish (Pangasianodon hypopthalmus) is due to its relatively fast growth. Efforts to overcome the need for large and high quality feeds are needed to improve feed engineering through the administration of Effective Microorganisms 4 (EM4) bacteria in the hope that the protein in the pellet can increase and the texture is improved so that fish digestibility increases. The study design used was a complete randomized design (CRD) 4 (four) treatments 3 (three) replications with ANOVA analysis. Catfish weighing 5 ± 0.3 grams / head with a length of 8 ± 0.5 cm are fed commercially fermented pellet 0.5 ml EM4 / 50 ml water. 1.0 ml and 1.5 ml per kilogram of feed with protein values P0 35.1282%, P1 32.8506%, P2 27.5527%, and P3 32.3208%. The experimental results showed that absolute growth were respectively P0 2.1 grams, P1 2.3 grams, P2 1.9 grams and P3 2.1 grams and absolute length P0 1.8 cm, P1 1.8 cm, P2 1.5 cm and P3 1.7 cm. Graduation of live fish until observation day 20 amounted to 100% then entered day 30 P0 93.33% cm, P1 93.33%, P2 83.33% and P3 90.00%. Conversion of feed P0 1.3, P1 1.0 P2 1.2 and P3 1.1%.

Abstract

Maggots is an organism derived from the eggs of the black fly, Hermentia illucens (black soldier fly, BSF), which undergoes metamorphosis in the second phase after the egg phase and before the pupa phase which then turns into an adult fly. The purpose of this study was to analyze the utilization of organic waste substrate on the production of BSF maggots cultivation. This research was conducted outdoor at the Freshwater Aquaculture Fisheries Center (BPBAT) Sungai Gelam Jambi with a completely randomized design (CRD) with 4 treatments and 3 replications; Treatment A: PKM (palm kernel meal) 100%, B (PKM 50% + cabbage vegetable waste 50%), C (PKM 50% + coconut pulp 50%) and D (PKM 50% + coconut pulp 25% + vegetable waste cabbage 25%). The average yield parameter of high maggots biomass in treatment A was 673.67 g/4 kg substrate and the lowest biomass in treatment D was 239.67 g/4 kg substrate. For the average weight and length of the best maggots in treatment A (0.20 g/individual) and (1.83 cm), the lowest was in B (0.12 g/Ind. and 1.58 cm). The highest was in treatment B (5,182.31 individual/4 kg substrate) and the lowest was in D (1,479.44 ind./4 kg substrate. The highest bioconversion value of maggots to organic matter OSE (organic substrate efficiency) was highest in treatment A (16, 84%) and the lowest was in D (5.99%). Technically, treatment A was slightly better than B, while economically the best organic substrate medium for maggots cultivation was in treatment B with a production cost of Rp. 7.257 and the ECR (economic conversion ratio) value of 5.81 was lower than the other 3 treatments. Keywords: Maggots, black soldier fly, Hermentia illucens, organic waste. ABSTRAK Maggots merupakan organisme yang berasal dari telur seranga lalat hitam, Hermentia illucens (black soldier fly, BSF). Tujuan penelitian ini yaitu menganalisis pemanfaatan subtrat limbah organik terhadap produksi budidaya maggots BSF. Penelitian ini dilaksanakan di Balai Perikanan Budidaya Air Tawar (BPBAT) Sungai Gelam, Jambi dengan rancangan acak lengkap (RAL) 4 perlakuan 3 ulangan yaitu perlakuan A : PKM (palm kernel meal) 100%, B (PKM 50% + limbah sayur kol 50%), C (PKM 50% + ampas kelapa 50%), dan D (PKM 50% + ampas kelapa 25%+ limbah sayur kol 25%).Rata-rata biomassa tertinggi didapatkan pada perlakuanA (673,67g/4 kg subtrat) dan biomassa terendah dihasilkan pada perlakuan D (239.67g/4 kg subtrat). Untuk bobot rata-rata dan panjang maggots terbaik dihasilkan pada perlakuan A (0,20 g/individu dan 1,83 cm/individu), terendah pada B (0,12 g/individu dan (1,58 cm). Jumlah populasi maggots yang terbanyak dihasilkan pada perlakuan B (5.182,31 ind./4 kg subtrat) dan terendah pada D (1.479,44 individu/4 kg subtrat). Nilai biokonversi maggots terhadap bahan organik OSEterbaik (organic substrate efficiency) tertinggi pada perlakuan A (16,84%) dan terendah pada D (5,99%). Secara teknis perlakuan A sedikit lebih baik dari B sedangkan secara ekonomi media subtrat organik terbaik untuk budidaya maggots terdapat pada perlakuan B dengan biaya produksi sebesar Rp. 7.257 dan nilai ECR (economic convertion ratio) sebesar 5.81 lebih rendah dari ke 3 perlakuan lainnya.
