The purpose of this study was to determine the effect of the composition of feed from vegetable waste on the growth of tilapia (Oreochromis niloticus). This research was conducted for 35 days, starting from June to July 2020, located in Kelurahan Betungan RT. 50 Districts Selebar Bengkulu City. The container used is a tarpaulin pool with a length of 1 m, a width of 0.5 m, and a height of 0.5 m totaling 16 units. The size of the fish used in this study was 7-8 cm. The design used was a completely randomized design (CRD) consisting of 4 treatments and 4 replications in order to obtain 16 treatment units in which treatment P1 = 5% water spinach, P2 = 5% green cabbage, P3 = 2% water spinach + 3% green cabbage and P4. = 3% Kale + 2% green cabbage. To determine the effect of the additional feed composition of vegetable waste on the growth of tilapia (Oreochromis niloticus), an analysis of variance was carried out at the 5% and 1% levels. Meanwhile, to see the best additional feed, a further 5% BNT test was carried out. The parameters observed during the study were fish growth which included absolute weight, absolute length, feed conversion, feed efficiency, feed conversion, and survival. The results showed that the additional feed composition of kale and green cabbage vegetable waste had a very significant effect on the growth of tilapia (Oreochromis niloticus), conversion, and feed efficiency, but had no effect on survival. The growth in absolute weight and length, feed conversion, and best feed efficiency was found in kale 5% and had a survival rate of 91%.

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%)

The purpose of this study was to determine the best stocking density for silk worms (Tubifex sp.) Against the addition of silk worms with a recirculation system. This research was conducted for 60 days starting in December 2019 until January 2020 at Jl. Bumi Ayu 8. Rt. 27 Rw. 06, Bumi Ayu Village, Selebar District, Bengkulu City. The container used is a container made of wood with a length of 100 cm, a width of 50 cm meters and a height of 15 cm as many as 16 pieces, the materials used are worm seeds, POC chicken manure, mud and soil. The design used was a completely randomized design (CRD) with 4 treatments and 4 replications so that 16 treatment units were obtained, namely: (P1) 20 gram / m2 stocking density (P2): 25 gram / m2 stocking density (P3): 30 gram stocking density / m2 (P4): stocking density of 35 grams / m2. To determine the effect of stocking density treatment on the addition of the number of individuals and the western biomass, analysis of variance was carried out at the 5% and 1% levels. Meanwhile, to determine the best stocking density, a further test of the least significant difference (LSD) was carried out at the 5% and 1% levels. The parameters observed during the study were (1) the increase in the number of individual silkworms (Tubifex sp) and (2) the total weight of silkworm biomass (Tubifex sp.) And TSS (Total Suspended Solid). The results showed that different stocking densities with the recirculation system had a very significant effect on the addition of the number of individuals, the weight gain of biomass and had a significant effect on the utilization of TSS value by silkworms (Tubifex sp) and the best increase in the number of individuals was found in stocking density (30 grams / container) with an average addition of 61,372 individuals / container and an average biomass weight of 150.074 grams / container and the best utilization of TSS values ??by silk worms (Tubifex sp.) is stocking density (30 grams / container) with an average mean TSS value 1.612 mg / L.

Feed is one of the most important elements to support a fisheries aquaculture business activity. This study aims to examine the effect of feed composition on the growth of tilapia (Oreochromis niloticus). The studi used a completely randomized design with three treatments and five replications. The treatments that tested were P1 = Kangkung Plant 100%, P2 = Lamtoro Leaf 100%, P3 = Kangkung Plant 50% + Lamtoro Leaf 50%. To find out whether there was an influence or not on the treatment, analysis of variance was performed, while to see the effect of the best composition, a further test of Least Significant Difference (LSD) was performed at 5% and 1% levels. The parameters observed were absolute length, absolute weight, feed conversion, feed efficiency and survival. The results showed that different feed compositions did not affect absolute length and survival, but significantly affected the absolute weight of feed conversion and feed efficiency. The highest absolute length growth was the spinach plant 50% + Lamtoro leaf 50%, while for absolute weight, the best feed conversion and feed efficiency were found in lamtoro leaves with a survival rate of 92.50%.

The design used in this study was a completely randomized design (CRD) which consisted of three treatments, namely experiment 1 (trash fish feed), Experiment 2 (mangrove snail feed), and Experiment 3 (cut chicken intestine feed) with eight replications, so that in getting twenty-four treatment units. To determine the effect or not, analysis of variance was carried out at the level of 5% and 1%, while to determine the effect of the best feed, the BNT Advanced Test (Least Significant Difference) was carried out. 5%. The parameters observed were weight growth of crabs, carapace length, carapace width, feed conversion, feed efficiency, and survival of mud crabs. The results showed that different supplementary feeding had a significant effect on the weight growth of mud crabs but had no significant effect on carapace length growth, carapace width, feed conversion, feed efficiency and survival of mangrove crabs. The best feed for the growth of mangrove crabs is chicken intestine with an initial weight of 105.2 grams and a final weight of 173.4 grams.

This study aims to determine the effect of cutting the best lobster shrimp organs on the percentage of moulting and survival of freshwater crayfish (Cherax quadricarinatus). This research was carried out from April to June 2020 at the Aquaculture Laboratory of the Faculty of Agriculture, Prof. University. Dr. Hazairin, SH Bengkulu. The research was carried out for 60 days. The container used is a plastic basket measuring 29 cm long, 19 cm wide and 11 cm high as many as 20 units. The number of lobsters used for each container is 3 tails, with an initial average length of 9-12 cm/head and an initial average weight of 25-50 grams/head. The design used was a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were P1 = No Cutting (Normal), P2 = Swimming Leg Cut, P3 = Claw Cutting, and P4 = Eye Cut (Ablation). Data were analyzed by means of variance (Analysis of Variance) with a test levels of 5% and 1%. If it has a significant effect, then it is continued with the BNT test (Least Significant Difference) with a test level of 5%. The parameters observed were the percentage and survival. The results showed that cutting the organs of freshwater crayfish (Cherax quaddricarinatus) had a very significant effect on the percentage of moulting, but had no significant effect on survival. The best organ cutting is found in the claw cutting experiment with a moulting percentage of 60%. The survival of all the treatments tried was between 73%-93%.
