Abstract

The fishery processing industry activities generally produce waste that is thrown away so that it does not experience reuse. The components of fish waste consist of the head, tail-bones, skin, and stomach contents that can be used as fish oil. The one of the problem in the use fish oil as a raw material for intermediate products is the difficulty in making a comparison ratio between fish oil and other ingredients, so we need to know the composition of fatty acids as a reference formulation for the application of waste utilization of tilapia oil. The method used is a quantitative method that is identifying fatty acids in tilapia oil. Data analysis uses Gas Chromatography (GC) as chromatogram data. Based on the results of the analysis that the composition of fatty acids from waste tilapia oil as follows: the dominant saturated fatty acids are palmitic fatty acids as much as 20.96%, the dominant monounsaturated fatty acids are oleic fatty acids as much as 22.63%, and fatty acids the dominant polyunsaturated fatty acid is linoleic as much as 16.77%. While the fatty acid components of EPA and DHA are found in very small quantities which is less than 0.01%.

Abstract

PT Aquafarm Nusantara is known as a modern industry in fish processing produced Tilapia Fillet as the main product that is routinely exported to several countries. Therefore, there are still some by products left such as bones, scales, skin, the content of belly, and head. This study conducted aimed to seek the characteristics and the quality of fish oil after purification. The method used was an experimental laboratory using eight different treatments on pale dose (charcoal) 1%, 2%, 3%, bentonite 1%, 2%, 3%, active charcoal 2% : 1%, and bentonite:active charcoal 1%, 2%. Parameters used are moisture content, melting point, free fatty acid, peroxide and iodin value, brightness and clarity. The best result of parameter analysis was showed by combining betonit: actice charcoal (2%:1%), it showed the moisture content 0.05 ± 0,02%, iodin number 121,87±2,55, peroxide number 7,92±0,00%, FFA 0,23±0,05, brightness 55,67±0,09% (L*),-1,09±0,03 (a*), 23,36 ±0.03(b*), and clarity 82,79 ± 0.51%T.

Abstract

The purpose of this study is to determine the effectiveness of the provision of pellets based on fish waste from TPI Jembatan Puri, Sorong City on the growth of catfish (Clarias sp.). The method used in this study is an experimental method including a test of feed to which includes 5 treatments and 3 replications. Fish meal making and fish waste material from PPI. The results of this study were preceded by previous studies that developed feed made from fisheries waste into pellets that were tested biologically to catfish, beginning with weighing the fish first as preliminary data for fish growth and then also measuring water quality as a factor affecting fish growth in a way live. The results of the study showed that the highest growth rate, the highest was obtained in treatment A (0.73% / day), for the highest feed efficiency in Treatment A, 1.49% for the best FCR, namely Treatment B, 0.28, and The best SR in treatment D was 93%. The conclusion from the results of the study showed that the growth of catfish in the nursery stage was quite effective for the growth of catfish by using fish-based feed even though the results obtained were not significantly affected (P <0.05) for each treatment using different feeds between commercial feed (pellets) and feed made from fish waste.

Abstract

Waha Tourism Community (WTC) is a conservation based tourism and managed by community. The increase of tourist activity is predicted will impact to increase of waste arise. Moreover, the coastal of WTC often gets marine debris that drifts away from other regions at a certain time. The aims of this paper are to know the comparison of waste generation from marine debris and the mainland, also to recommend the alternative of sustainable waste management system in WTC. The measurement of waste arise and composition using the CSIRO method, while the analysis method using IWM2. The results from the research showed that the amount of waste arise from marine debris is more than the mainland with ratio 5:1 (45,8 : 9,1 kg/day). The composition of marine debris consist of 81,6% organics; 5,5% Styrofoams; 3,1% rigid plastics; 3,5% soft plastics; 2,6% metals; 0,4 % glasses; 1,4% rubbers; 0,3% fabrics; 1,1% papers; dan 0,5% another waste. The composition of mainland waste are 63,6% organics, 13,2% rigid plastics; 9,9% soft plastics; 2,2% metals; 2,2 % glasses; 4,1% rubbers; 2,7% papers; and 2,1% another waste. Based on the waste composition in WTC, the most suitable waste management system is the recycling process, biological processing, and bringing the residue to the landfill, which can reduce the air emissions and water pollutions respectively by 1.570.398 gr CO2/year; 1.571.177 gr CH4/year; 34.601.010 gr GWP/year; 7.088 gr BOD/year; 12.146 gr COD/year; and 792 gr SS/year.

Abstract

The objective of this reserach was exploration to determine the location of fishing for for traditional Bubu fishermen by utilizing fishfinder technology. The method used in this research is descriptive exploration, obtained from interviews and field surveys. The sample locations are determined according to the distribution of fishing locations. Currently the traditional bubu fishermen in the village of Assilulu still use traditional tools as a pot in determining and finding the presence of fish to be caught, so that the productivity of the fish produced is not optimal, even though the source of fish in the waters of Assilulu is very abundant. So we need tools that can meet the productivity of responsiveness. Exploration results from 6 different locations with depth variations of 30-60 meters show comparisons from the point of view of fishermen and the use of fishfinder technology there are very different observations. the level of species diversity is in the position of the moderate index with a range of 1 ≤ H ’≤ 3. While in the uniformity index, all regions are included in the index high uniformity criteria between 0.73 - 0.82 and 0.78 - 0.92. For the dominance index, the index range is between 0.142 - 0.306 and 0.125 - 0.178. Then all fishing areas have low dominance, stable, and no ecological pressure. Functional fish diagrams show that the highest target fish fall at the pulpit and Nusi Hena fishing locations, with a percentage value of 19% each.

Abstract

Failure of tilapia culture in Indonesia in the hatchery, nursery and rearing segments mostly is caused by Streptococcus agalactiae infection. This study aimed to detect the characteristics of bacteria S. agalactiae NP104O, S01-196-16 and NMbO which infect tilapia in aquaculture. Bacterial isolation was carried out during an outbreak of streptococcosis, further analysis based on morphological and biochemical characters. The pathogenicity test was done by injecting bacteria intraperitoneally at a dose of 107 CFU fish-1. The results showed that all isolates was cocci, gram positive, negative catalase and negative oxidase. The three isolates had different concentrations and growth patterns until end of the observation. Pathogenicity test results obtained all fish injected with NP104O, S01-196-16 and NMbO bacteria appeared as clinical symptoms of melanosis, unilateral or bilateral exophthalmos, turbidity in the eye, curved vertebrae forming the letter C, erratic, and whirling. Hopefully, the results of this study can be used as a reference for prevention of streptococcosis infections in tilapia.
