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.

Abstract

One of the fish commodities that has great potential to be utilized by the fishermen of Seraya Island is Dingkis (Siganus sp.). During the spawning season, Dingkis experience a high price increase of 5 times the price during the non-spawning season, namely IDR 30,000-60,000/kg. Therefore, Seraya Island fishermen take advantage of this opportunity because Dingkis fish only spawn during a certain season, namely January-February, which coincides with Chinese New Year (Imlek). The aim of the research is to determine the income of Seraya Island fishermen during the Dingkis spawning season and the influence of the price of Dingkis, the number of Dingkis fish caught, and the number of other fish catches on the income of Seraya Island fishermen. The research was conducted on Seraya Island, Batu Legong Village, Bulang District, Batam City in February 2023. Data analysis was used to answer the first objective, namely by calculating income, the second objective was to test the influence of the independent variable on the dependent variable using SPSS type 26 software. The research results show that the average income of Seraya Island fishermen during the Dingkis spawning season is IDR 9,001,143/month. Partial test results on the number of catches of Dingkis fish have an effect on the income of Seraya Island fishermen. The price of Dingkis fish and the number of other fish caught have no influence on the income of Seraya Island fishermen.

Abstract

Success in operating the boat lift net fishing gear is influenced by many factors, one of which is the light tool as a fish attractant. This research conducted trials on adding fish LED aids to the gouging of the boat lift net while the mercury lamp power was reduced. This was done to see to what extent the addition of LED fish aids impacted the effectiveness and efficiency of the boat lift net. Therefore, this research aims to determine the effectiveness and efficiency of boat lift net with the addition of fish LED aids. In collecting data, the methods used were experimental and interview methods. The research results show that the addition of fish LED aids can increase the effectiveness value of the pry chart, namely 112.39% compared to the control boat lift net. The operation of the boat lift net is also more efficient with the installation of fish LED aids. This can be seen from the greater number of catches produced on the boat lift net fitted with fish LED aids even though the mercury lamp power was reduced.

Abstract

Refrigeration machines in fishery companies are widely used to maintain the quality of seafood products to keep them fresh. These machines are quite complex, so operating them correctly is crucial, as fatal operational errors can lead to the damage of the refrigeration equipment. The absence of written SOPs has the potential for non-standardized operations. Therefore, this article aims to develop Standard Operating Procedures (SOPs) for operating refrigeration machines on fishing vessels. To achieve this goal, data from the refrigeration system is used, and competent machine crew members are involved to obtain valid data. The data obtained is analyzed using a quantitative descriptive method. A proposed design of Standard Operating Procedure (SOP) with a cross-functional flow chart diagram has been produced as a guideline for operating refrigeration machines on fishing vessels. Based on the analysis, this SOP Draft has met the eligibility criteria for use. The SOP this machinery are highly significant in assisting the machine crew in ensuring that the machines are operated in a controlled manner following the correct procedures.

Abstract

Vaname shrimp (Litopenaeus vannamei) culture in BPIU2K Karangasem will produce waste from metabolism and leftover feed that contains organic material. This waste will cause environmental problems if not properly processed. This study aims to determine the quality of wastewater and the effectiveness of WWTP performance so that it can be used to generate policy recommendations for improvements in wastewater management. Water samples are taken in the morning using composite technique at five points in the IPAB inlet and outlet, each consisting of 1 liter with three repetitions.The results showed water quality of WWTP outlet from first week to third week have reached quality standard for physical parameters such as TSS and turbidity, and chemical parameters such as BOD and nitrate. However, did not reach quality standard for chemical parameters such as phosphate, H2S, nitrite, and ammonia. Removal efficiency in processing units can be used to determine the effectiveness of WWTP and will be effective if efficiency value is in the range of 60% < x = 80%. First week, WWTP in BPIU2K Karangasem showed its effectiveness on several parameters such as BOD and nitrate. Second week, the effectiveness was shown for BOD, phosphate, nitrate and ammonia. Third week, the effectiveness was shown for TSS, BOD, phosphate and H2S. The effectiveness of WWTP for each parameter differs every week due to the cultivation waste water coming from various activity units and the IPAB is still effective in treating wastewater because the five tested parameters still meet the quality standard.
