The Impact Of Oil Spill To The Total Petroleum Hydrocarbon (Tph) Concentration In Fishes At North Coastal Of Karawang Regency, West Java Province

The coastal area is one of the areas that is quite vulnerable to the threat of pollution caused by human activities, including pollution caused by oil spills (hydrocarbons) in the sea. The incident can be caused by several factors including the explosion, leakage of petroleum pipelines on the seabed, leakage of tanks or petroleum tankers at sea and disposal of waste petroleum products into the environment. Oil spills continuously can cause environmental contamination and pollution both aquatic and terrestrial. If the petroleum hydrocarbons enter sea waters, some of them will be absorbed by aquatic organisms because the nature of the petroleum hydrocarbons is difficult to decompose in waters. The intentional and unintentional entry of hazardous and toxic substances into marine ecosystems such as petroleum hydrocarbons and chemical solvents resulting from industrial wastes has become a serious problem for human health and the environment. The purpose of this study was to determine the concentration of Total Petroleum Hydrocarbon (TPH) contained in fish in coastal waters of Karawang Regency, West Java Province. This research was conducted in September-November 2019 by taking several fish samples at Ciparage Jaya Fish Auction Place, Betok Mati and Sungai Buntu Rive with a total sample of 24 fish, and taking seawater samples in the three study sites. TPH analysis was carried out at the Integrated Chemistry Laboratory, Bogor Agricultural University. TPH values in fish at Ciparage-1, Ciparage-2, Betok Mati and Sungai Buntu stations, in general, have different mean values but are almost uniform, each at 6.82; 6.82; 7.45 and 5.12 mg/kg. Based on the average TPH concentration in fish, it can be said that the average TPH in fish at Betok Mati station is relatively higher compared to other stations. TPH values in all fish samples exceed the safe threshold, which is a maximum of 0.002 mg/kg. Based on the results of the Bioaccumulation factor (BAF) analysis showed that the average TPH in fish was 6.55 mg/kg and the average TPH in the waters was 11.23 mg/l, so the BAF value was 58.35 which means that the absorption rate of TPH by fish organisms against the concentration of TPH in the waters of 58.35%. The analysis shows that the value of Ecological Hazard Assessment (EHA) is 3743.33 which means that the level of influence of the hazard on ecosystems and organisms is 3743.33. This value exceeds the recommended threshold according to the European Union, which is a maximum of 0.002 mg/l

EVALUATION OF THE VALUE OF AMMONIA, NITRATE, AND NITRITE ON CULTIVATION MEDIA OF CATFISH FED MAGGOT

Water quality is a limiting factor of life for aquatic biota, especially biota that lives in a pond. Therefore, water quality management is very necessary so that cultivation activities, especially ponds can continue and do not cause negative impacts on the surrounding environment. Various factors can decrease the water quality of aquaculture ponds one of which is from the remnants of feed and fish manure. Feed is one of the contributors to the dissolved organic matter in the cultivation pond. Maggot or black shoulder fly larvae are one of the alternatives that can be used as fish feed. Maggot has a high animal protein content of 30-45%, so it is very effective to be used as an alternative to additional feed in fish farming. The purpose of this research is to find out the difference in pond water quality between ponds by using maggot and pond feed by using pellet feed. The data taken in this study is primary data using the Complete Randomized Design (RAL) method with 3 treatments and 3 replays in each treatment. These treatments include Full Maggot Control (MU), 50% pellet, and 50% maggot (PU). Data obtained include; ammonia. Nitrites, and nitrates. The results showed that the average final value of ammonia, nitrite, and nitrates respectively treatment is KU ( 0.22 mg / L, 0.44 mg/L, 3.667 mg/L), PU (0.022 mg/L, 0.042 mg/L, 3.433 mg/L), MU (0.046 mg/L, 0.028 mg/L, 2.653 mg/L). The results illustrate the conclusion that the provision of maggots as an alternative and additional feed can improve the quality of aquaculture water

SEED DISTRIBUTION AND MONEV APPLICATION GUIDELINES FOR RAISING SEA TILAPIA FOR VILLAGE FISH CULTIVATION COMMUNITIES IN CIBUAYA DISTRICT, KARAWANG REGENCY

In 2021, the Karawang Marine and Fisheries Polytechnic Fish Cultivation Study Program has carried out community service activities by spreading seeds and Monitoring and Evaluation of the Application of Salin Tilapia Enlargement Guidelines for the Fish Cultivator Community of Sedari Village, Cibuaya District, Karawang Regency.

Hierarchical Neural Network Implementation: Emotion Recognition for Food Security Comments on Twitter

Modern Hierarchical Neural Network (HNN) implementation combines several deep learning algorithms working together, connected in a hierarchy layer. For this HNN architecture to work well, the problem and the data must be in a hierarchical format. Emotion recognition is the best example of a layered problem where each emotion is attached to a sentiment. This research proposes an HNN model to solve the emotion recognition problem with three deep learning, one for the sentiment in the first layer and two models for the emotion prediction in the second layer. There are two combinations to be compared, full-LSTM and full-CNN. Surprisingly, the overall HNN performance for both combinations is similar, and both are below a control model without HNN architecture. However, solving the emotion recognition problems in the food security domain was still possible despite poor performance. The application result creates a rough estimation of what people feel about the current food security trend
