Abstract

Conventional catfish culture in Ogan Ilir (OI) have not optimal production, it can be increased by biofloc and aquaponics with local swamp bacteria as a starter. The purpose of this study was to apply biofloc technology and a combination of aquaponic-biofloc to increase the productivity of catfish (Clarias sp.) rearing. The study used two ponds, a biofloc circular pond and a combined biofloc and aquaponic (biofloqua) for two months. The results of the specific growth rate of fish in the aquaponic biofloc system were higher than that of the biofloc system alone. The survival of the fish during two rearing months of the Biofloqua system was 100% while the Biofloc system was 92-96%. The water quality data that measured were temperature, 30.3–31.9oC, Dissolved oxygen 4.5–7.2 mg.l-1, pH 6-7, and ammonia concentration 0.27-0.71 mg.l-1 in the biofloc system and 29.5-31.3oC, 4.7-7.4 mg.l-1, pH 6-7, 0.20-0.53 mg.l-1 in biofloqua system, respectively. The floc volume formation rate in the biofloc system alone reached 1.1 ml.l-1 per day, which was above the floc formation rate for the biofloqua system 0.42 ml.l-1 per day, due to the use of nutrients for plant growth. The combination of biofloc and aquaponics showed more optimal growth performance and both were efficient in feed (Food Conversion Ratio / FCR <1.00). Although the results of the 5% level t test showed no difference in the performance of the aquaculture biota between the two systems, Biofloqua can be an alternative to increase fish farmer income by harvesting vegetables and fish together.

Abstract

Pangasius catfish rearing ponds and swamp waters are types of stagnant waters (lentic) that are commonly found in the South Sumatra region. Cyanobacter is a group of phytoplankton that plays an important role in the management of aquatic area, but it is not widely known which species is the most dominant in swamp waters. This study aims to determine the types of cyanobacter that are abundant in the swamps and Pangasius catfish cultivation ponds in Ogan Olir, South Sumatra. This research has been carried out by cyanobacter isolation from the swamp water and the pond, isolate liquid cultivation, DNA isolation, 16S rRNA gene amplification and DNA amplicon sequencing. The sequencing results were analyzed using BLAST (Basic local alignment search tool-nucleotide) and MEGA 6 with the help of NCBI gene bank data to obtain a phylogenetic tree for predicting the identity of the cyanobacter isolates. Based on the morphological characters, it is suspected that the pond isolates are similar to Synechoccocus and swamp isolates similar to Microcystis genera. The amplification of cyanobacter DNA using the PCR method with the universal 16S rRNA 63F (Forward) and 1387 R (Reverse) resulted 1302-1307 base pairs. Analysis using BLAST showed that the cyanobacter isolates from ponds have 91% similar to Uncultured Synechoccocus sp. from Australia, while the swamp isolates have 86% similar to Microcystis sp. from China. Key words : Cyanobacteria, Microcystis, PCR, Phylogenetic, Synechococcus

Abstract

The water pH of swamp land is generally low (below 4) and becomes a constraint in catfish culture that requires pH 6.5-8.5. In this current study, the low pH value of water was overcome by liming using lime produced from the mussel freshwater shells. The purposes of this study were to determine the best dosage of lime derived from mussel freshwater shells to increase the pH of swamp water, as well as its effect on the survival rate and growth of catfish fingerlings. This study used Completely Randomized Design (CRD) with 5 treatments and 3 replications. The treatments used were the different dosages of lime derived from mussel freshwater shells (P1=4,000, P2=5,000, P3=6,000, P4=7,000 kg/ha equivalent CaO) and calcite (CaCO3) as control (P5= 6,000 kg/ha equivalent CaO). The result showed that P4 was the best treatment according to data of swamp water pH increased from 3.4 to 8.23, soil pH increased from 3.4 to 8.22, survival rate (100%), absolute growth of weight (56.59 g) and length (13.37 cm) and feed effeciency (113.06%).

Abstract

The Fish Under Crew Cultivator Group is located in Pulau Semambu Village which was established in 2016 with fish commodities, including fish ponds. The aquacultured fish can already respond to the artificial feed given. However, the use of feed by the aquaculture fish is still not efficient. This is a problem faced by fish farmers, including in the Fish Under Crew group. The addition of papain enzymes in feed can increase feed digestibility so that fish can utilize feed more efficiently. The purpose of this community service activity is to apply the use of the papain enzyme in artificial feed to increase feed digestibility and its effect on the growth and production of aquaculture fish. Methods of activity include: 1) socialization of activities, 2) counseling to group members and the community in Pulau Semambu Village, 3) providing assistance in the form of two tarpaulin ponds with iron frames and their accessories, 4) Application of board enzymes to fish through fish rearing activities for 1 year. months, using two treatments, namely 0% papain enzyme in feed as control (P0) and 0.75% papain enzyme in feed (P1). Socialization and counseling were carried out by involving group members and the community in Pulau Semambu Village. The community understands the extension material presented and is very enthusiastic to apply it in their cultivation activities as evidenced by very interactive question and answer sessions during the discussion session and answers to the questionnaires given to participants. The pool assistance was received by group members, accompanied by village officials and Bumdesma administrators. In fish rearing by applying the addition of papain enzyme to feed, it gave a higher absolute growth rate (absolute weight growth 0.41 g and absolute length 0.56 cm) than commercial feed without the addition of papain enzyme. Based on the activities that have been carried out, UPR Fish Under Crew has applied the addition of papain enzymes to feed for aquaculture fish. The results obtained can increase the growth of the pond fish that are kept and the use of feed is more efficient.

Abstract

Nutrients (C, N, and P) can affect the growth and biochemical content of Arthrospira platensis. Ethanol can be a potential carbon source compared to glucose and acetic acid. Glycerol is also potential as a carbon source for the growth of Arthrospira platensis. This research was carried out from June to July 2021 at the Aquaculture Laboratory and Experimental Pond Laboratory of the Aquaculture Study Program, Sriwijaya University. The research method used Completely Randomized Design (CRD) factorial with 2 factors consisting of the first factor with 3 treatments and the second factor with 2 treatments and 3 replications. The inoculant was cultured in liquid fertilizer technical F/2 media for culture stock as initial inoculum with a density of ± 1.0 g L-ˡ. Parameters observed were the density, the specific growth rate, and water quality. The results showed that M1S3 treatment had the highest density with a value reaching 4.95 g L-1 and the highest specific growth rate of 0,33% per day. ANOVA test result showed that the addition of carbon sources in the culture media of fertilizer and technical waste had a significant effect (P<0.05) on the growth rate of Arthrospira platensis. The water quality parameters of each treatment were suitable for Arthrospira platensis culture.

Abstract

Kualitas air tambak yang menurun seringkali disebabkan kurangnya pengelolaan tanah dasar yang berakibat kurang optimalnya produksi budidaya ikan. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik fisika dan kimia sedimen tambak tradisional ikan bandeng di Banyuasin II, Kabupaten Banyuasin, Sumatera Selatan. Hasil dari penelitian menunjukkan bahwa tekstur tanah pada masing masing tambak yang disampling tergolong lempung berpasir. Bahan organik tanah pada setiap tambak cukup tinggi dengan nilai berkisar antara 7,08-14,15%. pH tanah tergolong asam-sangat asam dengan nilai 3,38-4,63. Hasil uji kadar besi menunjukkan nilai yang sangat tinggi pada setiap tambak, berkisar antara 2,28-42,12 mg kg-1. Kandungan kalsium dan magnesium cukup rendah, yaitu      4,81-9,91 Cmol kg-1 dan 0,96-3,09 Cmol kg-1. Hasil analisis akumulasi sedimen menunjukkan nilai mulai dari 12,14 cm per tahun hingga 22,86 cm per tahun. Meskipun karakteristik tambak belum menunjukkan masalah yang berat untuk pemeliharaan ikan bandeng, namun produktivitas tambak menjadi kurang optimal. Tanpa pengelolaan tanah dasar yang baik pada tambak, diperkirakan kualitas tambak akan terus menurun untuk pemeliharaan ikan yang akan datang
