Abstract

Grouper (Epinephelus sp.) is a marine fishery commodity that is widely cultivated in marine cages and ponds. The export market demand for grouper fish continues to increase every year by 30.75% every year, so there is a need for improvement, through various technological applications. The main obstacle in cultivating grouper fish in ponds is the decline in water quality and disease attacks, which can cause up to 100% crop failure, just 3 – 5 days after infection. One effort that can be implemented is the cultivation method with the Immuno-Probiocirculation System (SIPBR). Brondong sub-district is one of the areas in Lamongan which has large fisheries potential, especially for breakwater water pools, which are the top among other districts. There have been many cases of grouper deaths in ponds to date, which are caused by disease attacks and water quality. The aim of this community service activity is to apply the Immuno-Probioculation System fish aquaculture technology in traditional plus pattern ponds (SI-PBR), increasing grouper fish production in Lamongan Regency, East Java. Observational method which includes socialization / counseling, planning and guidance for implementing SI-PBR technology in one period (three months). These results show positive indications. There is an increase in farmer knowledge, the SI-PBR method can reduce ectoparasite infestation and increase grouper yields from 272.43 kg / ha to 87.66 kg / ha, meaning an increase of 334%. The conclusion from this activity is that the SI-PBR model can increase fish production and can be applied in wider areas in the Lamongan region.

Abstract

The purpose of this study is to determine the influence and determine the optimal dose of moringa leaf extract and kencur in feed on the growth performance of catfish seeds. This research was carried out at the Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences Padjadjaran University from February to March 2024. Sampling in this study used an experimental method using a Complete Random Design (RAL), the growth data obtained was analyzed using the analysis of the F test variety fingerprint (ANOVA / Analysis of Varience) and for the water quality data was analyzed descriptively. The results of this study, namely the addition of 150 mg/kg of moringa leaf extract and 250 mg/kg of kencur extract to feed had an effect on improving the growth performance of catfish seeds which was more optimal than other treatments, as shown by an increase in the percentage of absolute length growth (4.2 cm), absolute weight (57.58 g), SGR (3.80%), FCR (1.44%), EPP (68.90%), and SR (100%). The water quality values during fish rearing are in the optimal range including temperature (27.5-28.3°C), pH (7.0-7.5), and DO (5.2-7.5 mg/L).

Abstract

Catfish is one type of carnivorous fish that can adapt to artificial feed formulations. attractants from animal sources such as earthworm meal can be used as attractants in feed. Attractants added to feed in small amounts can stimulate appetite and fish growth. This study aims to determine the best dose of earthworm meal addition as an attractant in feed so that it affects the growth of catfish. This study used experimental method of Completely Randomised Design (RAL) with 5 treatments and 3 replicates. The treatment used was the addition of earthworm meal attractant in catfish feed at a dose of 0% (A), 5% (B), 7,5% (C), 10% (D), and 12,5% (E). The results showed that the addition of 10% earthworm meal attractant in feed (Treatment D) was the best dose for catfish growth which was able to increase absolute length growth by 6,85 cm and specific growth rate (SGR) by 4,74%/day.

Abstract

This research aims to analyze the marketing channels for koi fish at the UPTD Freshwater Ornamental Fish Promotion Center in Rawalumbu District, Bekasi City. This research was carried out from March 2024 to April 2024 using the snowball sampling method or snowball technique. The parameters analyzed are marketing channels, marketing margins, revenue and cost balance (BCR), and transportation techniques for koi fish. This koi fish marketing channel analysis was carried out at the UPTD Freshwater Ornamental Fish Promotion Center in Rawalumbu District, Bekasi City. Based on the research results, the results showed that the koi fish marketing channel pattern at the UPTD Freshwater Ornamental Fish Promotion Center in Rawalumbu District, Bekasi City has two fish marketing channel patterns. In the channel I pattern, it consists of (cultivators, collectors, wholesalers, retailers and final consumers), channel II (cultivators, collectors, retailers and final consumers). The most efficient marketing channel of the two existing channels is channel II, seen from its revenue and cost balance (BCR) value of 1.3, It is recommended that further research be carried out in this research using a different problem approach method so that information about koi fish marketing can be used better.

Abstract

Fish breeding is one of the businesses that many fisheries farmers are involved in Sukamandijaya Village is one of the areas producing freshwater fish seeds, especially patin fish (pangasius fish). The production process of patin fish nurseries takes 4-5 weeks. Farmers will receive their income if all patin breeds are sold. There are several obstacles for patin fish nursery farmers related to capital, which still uses personal funds that hamper the next production process. Patin nursery farmers who have narrow marketing will need more time so that all fish breeds are sold, thus hampering farmers' income. This study aims to analyze the average costs required, revenue, income feasibility, and related evaluation of the patin fish breeding business in Sukamandijaya Village. The number of respondents in this study was 28 respondent farmers in Sukamandijaya Village. The analysis used in this study is the calculation of farm income, R / C Ratio, price BEP, production BEP, and revenue BEP. The results showed that the patin fish breeding farm in Sukamandijaya Village had fulfilled the feasibility criteria. The average variable cost required in one production is Rp 4.477.357, and the average fixed cost required in one production is Rp 1.636.801. The average total cost for Rp 6.109.417/production with total revenue obtained of Rp 13.178.610/ production and total income of Rp 7.069.193/production.

Abstract

In its development, rice and fish cultivators (pond rice fields) in Karangbinangun District find it difficult to determine whether the production yields they will receive result a profit or a loss. Because remember that there are many problems by cultivators such as the difficulty of getting fertilizer, the high cost of fertilizer, fish seeds are not always available, labor is hard to find, while the majority of cultivators in Karangbinangun District are small scale, so the capital they have is also small. Therefore, there is a need for research on 1) analysis of the costs incurred by pond rice fields cultivators for one year, 2) profit analysis, and 3) Profitability analysis. The analytical method used in this research is business financial analysis which consists of cost analysis, profit analysis and profitability analysis. The result of the research is average total costs incurred by rice-fish cultivation businesses (pond rice fields) are IDR 69,041,732.03/Ha/Year and the revenue is IDR 153,560,000/Ha/Year so that the profit received is IDR 84,518,267.97/Ha/Year. The R/C Ratio value is 2.22 and the net profit ratio (Net Profit Margin) is 55.04%, which means that the rice-fish cultivation business (pond rice fields) is efficient and the farmer's decision to undertake rice-fish cultivation (pond rice fields) it's still very much worth continuing
