Andriyanto Samin — 2023-12-15

Kedindingan Island is one of the Marine Conservation areas in East Kalimantan Province with rich natural resource. This study aims to determine the extent of coral distribution and health, determine the health condition of live coral cover and to formulate management strategies in Kedindingan Island for the realization of sustainable coral management. The results of the analysis using Landsat 8 imagery showed live coral was 55.44 Ha in 2015 and 48.06 Ha in 2022. Love coral cover in stations 1,2, and 4 were in good category i.e. 52,53$, 53,6%, and 60,34%, respectively . whilst in station 3 31,34% was moderate category. There are three priority management strategies for coral ecosystem management in Kedindingan Island, the first is to create a team in each region consisting of policy makers, academics, and the community, the second is to increase the role of NGOs and local communities in monitoring and supervising coral ecosystems, and the third is to improve management and develop rehabilitation methods and monitor corals regularly in Kedindingan Island.

Analysis of Compliance Level of Fishing Activities In The Natuna Sea

Dwi Santoso Wibowo — 2023-12-15

Illegal fishing in Indonesian territorial waters, especially by foreign fishermen, has harmed the Indonesian state financially, because it has contributed greatly in reducing productivity and catches very significantly. It has has also threatened the sustainability of the utilization of Indonesia’s marine fishery resources. Economic losses due to IUUF are not only in the form of state income which reaches the range of Rp. 30 trillion per year, but also the loss of opportunities to utilize fish resources of around 1 million tons of fish each year that can be caught (harvested) by Indonesian fishermen, and what happens is in fact stolen by foreign fishermen. entering Indonesian waters. Foreign fishermen who often enter Indonesian waters, among others, come from Thailand, Vietnam, the Philippines, and Malaysia. To prevent and overcome IUUF activities, one of the steps taken by the Ministry of Maritime Affairs and Fisheries (KKP) of the Republic of Indonesia through the Directorate General of Supervision of Marine and Fishery Resources (DITJEN PSDKP) is to supervise fisheries such as fishing activities in the fisheries management area of the Republic of Indonesia. Supervisory implementation is carried out by the Technical Implementation Unit (UPT) PSDKP. UPT Directorate General of PSDKP in handling its duties is supported by the Marine and Fishery Resources Supervision Unit (PSDKP Satker) and Marine and Fishery Resources Monitoring Post (PSDKP Post) spread throughout Indonesia. In carrying out its duties, the Fisheries Supervisory Vessel may stop, inspect, carry, and detain ships suspected of violating the law to the nearest port for further processing. In addition, based on Law No. 31 of 2004 concerning Fisheries, as amended by Law No. 45 of 2009, in certain cases Fishery Supervisory Vessels, in this case, fishery supervisors or Fisheries Civil Servants Investigators, can also take special actions in the form of drowning. The high level of fishing activity in the Indonesian State Fisheries Management Area 711 must be accompanied by adequate monitoring activities to ensure compliance by business actors, both industrial scale and small fishermen, so that the sustainability of fisheries resources can be maintained.

Risk Analysis of Fresh Lemuru Fish Supply Chain at Banyuwangi Port

Fitriana Dina Rizkina — 2023-12-15

The abundance of lemuru fishery products around Coastal Fisheries Port in Muncar has led to the growth of a processing industry cluster made from lemuru fish which produces canned fish (sardines, tuna), fish flour and oil as well as frozen fish around Muncar port. Factories or industries whose raw materials require a large amount of money to move materials that are easily damaged will tend to choose their industrial locations around sources of raw materials. This shows that Indonesian people are aware of the nutritional contribution of consuming fish. The amount of production and consumption of this fish is also influenced by the season and weather so that the supply of caught fish is uncertain but the demand for fish is always increasing. Apart from that, other risks are inaccurate knowledge of fish handling, the distribution of caught fish that takes too long affects the decrease in the quality of fresh caught fish and the selling price of caught fish. Flying fish at Muncar Fishery Port is very dependent on the fishing season, so the availability of supplies fluctuates. The purpose of this study was to identify the supply chain structure and supply chain risks for lemuru at Muncar Fishery Port, analyze the highest risk factors in the lemuru supply chain at Muncar Fishery Port at each tier of fishermen, collectors and traders and recommends supply chain risk mitigation for lemuru fish for each tier at the Muncar Fishery Port based on risk identification.

Analysis of Heavy Metals in Shellfish, Sediment, and Waters in Seagrass beds Ecosystem in Selangan Village, Bontang City

Fatmy Yaumil Akhir — 2023-12-15

Selangan Hamlet is a water area in Bontang City where community activities are very active. Bontang City is an area that has a high utilization of coastal areas such as tourism, cultivation, trade, sea transportation services, and industrial areas. The impact of the industrial area on these waters is the contamination of these waters with heavy metals which will have an impact on aquatic organisms and the surrounding community who ultiize these waters. The purpose of this study was to identify the content of heavy metals lead (Pb), copper (Cu), magnesium (Mg), iron (Fe), and mercury (Hg). This research was conducted in January-June 2023 in Bontang waters, Selangan Hamlet. Sampling involyes analyzing water quality and testing heavy metals such as Cu, Pb, Fe, Mg, and Hg. The samples to be analyzed are water, sediment, seagrass and blood clams. The results of the analysis obtained in these waters, at the four stations, namely the south, east, west and north stations. At all stations in the heavy metal test Cu, Pb, Fe, Mg and Hg heavy metal content is only found in blood clams (Anadara granosa). In water, sediment and seagrass, the values obtained are still in normal conditions.

The Utilization of Pangas Catfish Fish Skin (Pangasius pangasius) in Making Skin Chips

Widya Pangestika — 2023-12-15

Catfish is a popular freshwater fish and is in great demand as a consumption fish because catfish meat has a delicious taste and is quite high in calories and protein. Catfish skin as a by-product of fillet production can be used as raw material for processing chips. This research aims to determine the effect of soaking ingredients on the physical and chemical characteristics of catfish skin chips. This research was carried out by making catfish skin chips through the process of first washing, first soaking with soaking materials, second washing, second soaking in spices, drying, cutting, frying, and packed. The treatment in this research is the soaking material (in the first soaking) used. There were 4 treatments with different soaking ingredients, including: P0 (control), P1 (lime), P2 (acetic acid/vinegar), and P3 (palm vinegar). After the skin chips with the 4 treatments have been produced, quality testing is carried out on the product. Tests were carried out on yield, consumer acceptability through hedonic testing, physical characteristics of skin chips through analysis of crispness, efflorescence and oil absorption, chemical characteristics through proximate analysis, and microbial contamination through ALT analysis. Treatment P1 is known to have the highest yield, crispness, oil absorption capacity, and efflorescence ability among other treatments. Next, the products tested for chemical content are selected based on the treatment that obtains the highest level of consumer acceptance. Based on hedonic testing, it is known that P1 is the treatment most sought after by consumers. From the results of the chemical analysis that has been carried out, the ash content and protein content of fish skin chips in P1 is higher than P0, but has a lower water content than P0. The Total Plate Number (ALT) value for each catfish skin chips parameter exceeds the standard limit of SNI 7388:2009, namely 5x10⁵ CFU/g.
