Abstract

The biofloc system is a solution for intensive cultivation activities. This is because in biofloc system the are heterotrophic bacteria that can reuse waste from cultured organisms so as to improve water quality. However, the biofloc system can cause high nitrite production if the dissolved oxygen concentration in the water is below the optimum value. High nitrite concentrations can cause brown nitrite, causing fish to suffocate even though the oxygen concentration in the water is sufficient. Polyculture can be a solution to reduce the concentration of biofloc so that brown nitrite can be prevented. Therefore, a research was conducted with the aim of knowing the effect of the composition of the best polyculture biota in order to produce high cultivation performance. The ratio of tilapia and catfish used included 80% catfish and 20% tilapia fish (treatment A), 70% catfish and 30% tilapia fish (treatment B), 60% catfish and 40% tilapia ( treatment C), and 100% catfish (treatment D). Maintenance is carried out for 60 days where feeding is done on a restricted basis. The results of the research carried out showed that the best FCR, ADG and SR were in treatment C with consecutive values of 1.27 ± 0.02 (FCR), 1.4 g/day (ADG) on the last maintenance day, 95.11 ± 1.02% (SR). This study shows that the performance of cultivation in biofloc systems in polyculture is better than monoculture.

Abstract

Fisheries-marine extension in mangrove forest management in Rembang has been conducted for some time, namely in 1988 until now. The problem identified is that the results of the extension program allegedly have not been implemented optimally and have never been assessed the status of its success thoroughly and especially in its sustainability status so that a fisheries extension strategy is needed. This study aims to formulate recommendations for fisheries extension strategies in mangrove management in Rembang. The analysis method used is Multi-Dimensional Scalling (MDS) through the RAPFISH (Rapid Assessment Technique for Fisheries) approach, this method is used to determine the sustainability status of fisheries extension. Sampling using purposive sampling method, with respondents from mangrove management communities and fisheries communities including fishermen, fish farmers and other fisheries business actors, as well as from the Rembang Regency Marine and Fisheries Agency. The results of this study obtained the sustainability status of fisheries extension in mangrove management in Rembang for organizing fisheries extension in Rembang which includes 5 (five) attributes of 69.89, meaning that sustainability is in the status of "quite sustainable" in supporting mangrove management in Rembang. Substance material in the form of fisheries management and technology and conservation is an attribute with the highest sensitivity value that most affects the sustainability dimension of organizing fisheries extension in Rembang with a value of 11.80.

Abstract

Rubber cassava root (Manihot glaziovii) bark contains an active substance known as Hydrogen Cyanide (HCN), which is toxic to red-blooded animals. This bark is abundant and readily available in the community’s surroundings. Therefore, this research aims to investigate the effect of using rubber cassava root bark at specific doses in eradicating red-blooded fish. The test animals used are Nile tilapia (Oreochromis niloticus). Each treatment is repeated three times and assigned specific codes: code A as a control with the application of 20 ppm saponin, and codes B, C, and D with the application of rubber cassava root bark liquid at 20 ppm, 40 ppm, and 100 ppm, respectively. The parameter used as the observation criterion is the mortality rate of the test animals over 6 hours with varying doses of rubber cassava root bark liquid. Based on the research results, it can be concluded that rubber cassava root bark liquid can be used as an alternative to replace saponin at 100 ppm. Further research is required to determine the most effective dose of rubber cassava root bark as a substitute for saponin in aquaculture.

Abstract

There are several types of purse seine in Sibolga, namely tuna trawls, snare seines and meeting trawls. The main catch from purse seine is pelagic fish. Purse seine catches are related to the mesh size of the fishing gear. The mesh size is small so it can catch more than 3 species of catch which are classified as non-environmentally friendly fishing gear. The aim of this research is to find out whether purse seine fishing gear in Sibolga is environmentally friendly fishing gear or not. The research was conducted March 1 – June 30 2021 at the Sibolga Fishing Port (PPN), The research was carried out at KM Samosir 08 on cob trawl fishing gear and KM Serasi Putra on cob trawl fishing gear. The data analysis used is a scoring analysis of environmentally friendly fishing gear criteria. Trawls and cob trawls are environmentally friendly fishing gear and meet the 9 criteria for environmentally friendly fishing gear. The score for the level of environmental friendliness of the tuna trawl fishing gear was 33 and the meeting trawl was 32.6 with the criteria being included in the group of very environmentally friendly fishing gear.

Abstract

Mussel shells are shellfish that live in freshwater and have two parts, namely the meat which is used in food and the shell which is still underutilized. Mussel shells (P. exilis) contain calcium and phosphate compounds that have the potential as hydroxyapatite. Hydroxyapatite is the main mineral component of teeth and bones. This study aimed to determine the hydroxyapatite characteristics of mussel (P. exilis) shells. The method in this study was an experiment with a calcination temperature of 700°C which was repeated 3 times and went through 3 stages including 1) sample preparation, 2) calcium oxide powder (CaO) extraction, and 3) hydroxyapatite synthesis with test parameters consisting of yield analysis, Ca and P levels, and functional groups. The hydroxyapatite characteristics of mussel shells were yield of 6.69%; Ca content of 50.13%; P content of 1.60%; hydroxyl groups were detected at wave number 3641.76 cm-1 and 3570.39 cm-1; phosphate group at wave number  1033.89 cm-1;  and carbonate group at wave number 1457.28 cm-1; 1448.60 cm-1 and 1419.67 cm-1.

Abstract

Pyrolysator performance testing has been carried out on the results of liquid smoke produced by pyrolysators with a multilevel condensation system using coconut shell fumes. The parameters tested in the pyrolysator performance test were time, temperature, heating rate, volume of liquid smoke and residual combustion in the form of charcoal. Test results using Gas Chromatography-Mass Spectrophotometry (GC-MS) show that pyrolysators with multilevel condensation systems produce liquid smoke with food grade quality so it is safe to use as a natural preservative for fishery products. The amount of liquid smoke produced by the pyrolysator with a multilevel condensation system is 24% and charcoal is 46%, from the pyrolysis process of 10kg of coconut shells for 5 hours. It can be concluded that pyrolysators with multilevel condensation systems have advantages in terms of productivity when compared to conventional pyrolysators, so they are very suitable for use in the liquid smoke industry.

Abstract

Ketapang (Glycinemax L. Merril) seeds have the potential to become a source of fish feed ingredients derived from vegetables because they are easy to obtain and contain high enough protein. This study attempts to analyze the effect of substitution of soybean flour using ketapang seed flour on the feed formulation of tilapia (Oreochromis niloticus). This study was an experimental study using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment tested was the concentration of ketapang seed flour, consisting of: A (control/ 0%), B (7%), C (9%), and D (11%). Fish maintenance done for 50 days with an initial size of 4 – 6 g. The observed parameters were absolute weight, absolute length, specific growth rate, feed afficiency, feed convertion ratio, survival rate and water quality. Data were analyzed using analysis of Variance (ANOVA) within 95% of trust. The result showed that substitution of soybean flour using ketapang seed flour on the feed formulation of tilapia (O. niloticus) could affect absolute weight, absolute length, specific growth rate. But did not affect feed afficiency, feed convertion ratio, or survival rate. The addition of 7% ketapang seed formulation gave the best results during the study.
