Abstract

The problem faced by fish farmers in Lingga is that the feed is quite expensive and rarely found on the local market. The existence of shrimp heads and fish bones are often found in Dabo as waste from processed shrimp crackers and fish balls that have not been utilized. The research aimed to evaluate the quality of fish feed from local fish meal, shrimp head meal and fish bone meal based on organoleptic, physical, and chemical tests. The treatments tested in this study consist of three threatments, namely: feed A (48%), feed B (35%), and feed C (comercial feed). The organoleptic showed that feed have a fibrous texture, typical coconut aroma, and brown color. The results of water stability showed that feed A (86,50 minutes±1,63), B (87,00 minutes±1,29), C (91,75  minutes±0,96) and dispersion of solids feed A (9,38% ±0,95), B (9,50%±0,71), C (8,63%±0,85). The sinking velocity showed that feed A (3,79 cm/s±0,23), B (3,32 cm/s±0,24), C (4,61 cm/s±0,18). The hardness level of feed A (91,63%±1,38), B (91,38%±2,66), C (94,63%±2,14). The proximate of feed has a moisture of 7,53% (A); 5,28% (B); 6,69% (C), ash of 19,95% (A); 17,85% (B); 12,03% (C), crude protein of 49,07% (A); 36,14% (B); 31,23% (C), crude lipid of 4,28% (A); 4,90% (B); 11,63% (C), and carbohydrate 19,19% (A); 35,84% (B); 38,43% (C). The results of  physical and proximate  indicated that ingredients local feedstuff have the potential as fish feed except moisture and ash.

Abstract

Surimi is Japanese, meaning crushed meat. To encourage fish consumption, products made from processed surimi are made more varied and interesting, such as fish dumplings. This research aimed to determine the differences in the sensory characteristics of surimi from different raw materials (swangi fish, kurisi fish, and kuniran fish). Apart from that, we also want to know the organoleptic and hedonic test results of fish dumplings made from different surimi raw materials. The surimi testing method includes an appearance test, folding test, and bite test on three different types of surimi (SU1 = kurisi fish, SU2 = swangi fish, SU3 = kuniran fish). Organoleptic and hedonic test methods for fish dumplings include appearance, smell, taste, and texture. The research results showed that there was a significant difference in the physical test of surimi (fold and bite test), while in the appearance test, there was no real difference. The surimi organoleptic test showed that there was no difference in smell and taste, while there were different results in appearance and texture parameters. The results of the hedonic test showed that panelists preferred sample SU1 on appearance and smell parameters, SU2 was preferred on taste parameters, and SU3 was superior on texture parameters.

Abstract

Incentive shrimp farming system has become a farming system adopted by most Indonesian farmers to rapidly increase pond productivity with high stocking densities ranging from 100-300 fish/m2. The study aimed to determine the growth performance and survival rate of Vannamei shrimp culture at PT Andulang Shrimp Farm, Sumenep, East Java with different plot sizes and stocking densities. In the augmentation method, 2 culture plots are used, each with an area of plot D4 (1,932 m2) with a stocking density of 177 fish/m2 and plot F3 (2,600 m2) with a stocking density of 172 fish/m2. In plot D4, the average body weight (ABW) was 26.45 g, the feed conversion ratio (FCR) was 1.63 and the survival rate (SR) was 74.05% with a total harvest tonnage of 4,845.64 kg. In plot F3, the average body weight (ABW) was 26.36 g, the FCR was 1.61 and the SR was 75.42% with a total yield of 6,674.42 kg. A high protein diet contributes to the growth of Vannamei shrimp. Optimal water quality and proper feeding can promote the growth of Vannamei shrimp.

Abstract

Ocean currents are the movement of sea water masses in a certain direction caused by several factors, namely wind, tides and bathymetry. Hydrodynamic modeling aims to determine the speed and direction of ocean currents in the waters of Bakau Bay through a two-dimensional model. The current pattern of the north season to the east season is influenced by sea water masses with an average current speed ranging from 0.22-0.24 m/s, while the south season to West season currents with an average speed of 0.04-0.26 m/s, this shows the meeting of different water masses so that the speed and direction of the current results in random or rotating currents. From the calculations of the normality test and anova test, it is known that the field current and model simulation values are normally distributed and there is no significant difference in values in the two data, so based on the RMSE value, it shows that the difference in values between the model simulation results and direct data measurements is relatively small. This also shows that the ocean surface current model created is sufficient to describe actual conditions.

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

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.
