ANALISIS PERKEMBANGAN JUMLAH FASILITAS DAN PENGUNJUNG DI KETAPANG URBAN AQUACULTURE MAUK TANGERANG BANTEN

Ketapang Urban Aquaculture (KUA) has important potential as a sector that can contribute to meeting food needs, developing the local economy and preserving the environment. This ecotourism development is a program from the Tangerang Regent as stated in Tangerang Regency Regional Regulation Number 1 of 2019 concerning the Medium Term Development Plan for the Tangerang Regency Region for 2019-2023. The problems that occur in tourist areas are tourism that can only last for a short time due to various factors and environmental damage caused by the development of facilities as well as visitors who do not pay attention to the carrying capacity of the area. This research aims to analyze the development of facilities, visitors and management in the Ketapang Urban Aquaculture Mauk Tangerang Banten mangrove tourism area so that it becomes a sustainable ecotourism. The research was carried out at Ketapang Urban Aquaculture Mauk Tangerang Banten starting from January-February 2024. This research is quantitative descriptive. Data collection stages, namely primary and secondary data collection. The data collection method was carried out by field surveys and interviews with managers of the KUA tourist area. The results of data on the development of facilities during their inception have not yet been redeveloped. Meanwhile, the development of the number of visitors is uncertain, with the highest number of visits obtained in April 2023, namely 30,157 people and the lowest in November 2023, 3,321 people. The management of Ketapang Urban Aquaculture (KUA) is also contained in the Regent Regulation Number 89 of 2022 which is the reference framework for KUA management. The recommendations that can be made by Ketapang Urban Aquaculture (KUA) are to provide several additional facilities that can attract visitors by paying attention to the carrying capacity of the area and carrying out evaluations based on visitor assessments. Facility development can be done with appropriate KUA management and marketing strategies

Physicochemical Characteristics and Dietary Fiber of Analog Rice from Seaweed (Sargassum sp.) and Beneng Taro Combination

Development of analog rice from Sargassum sp. and beneng taro combination is expected to be an alternative food to increase the amount of dietary fiber intake for the community. The aim of this research is to determine the best characteristics of analog rice from Sargassum sp. and beneng taro as a high fiber food. The concentration of added Sargassum sp. seaweed in this study were 0%, 5%, 10%, and 15%. The results showed that a concentration of 15% was the best treatment with a white degree value 1.23%; water absorption capacity 61% and swelling power 59.3%. The chemical characteristics of the best analog rice are 10.14% moisture content; ash content 4.14%; fat content 0.60%; protein content 5.69%; and carbohydrates content 79.44%. The dietary fiber of analog rice is 23.74%.</p

Microplastic characteristics of indian scad (Chanos chanos) and tilapia (Scomber japonicus) at Rau Market, Serang City, Banten

Mikroplastik dapat mencemari air, tanah, tumbuhan, hewan, hingga manusia. Sumber limbahmikroplastik di perairan tawar antara lain dari industri, pertanian, dan aktivitas antropogenik dimana keseluruhannya dapat menjadi sumber pencemaran mikroplastik di laut. Ikan nila(Oreochromis niloticus) dan ikan layang (Decapterus ruselli) merupakan ikan omnivora yanghidup di kolom air, di mana ikan nila dibudidayakan di perairan tawar sedangkan ikan layangditangkap di laut. Proses identifikasi mikroplastik menggunakan mikroskop. Sebanyak 158mikroplastik telah ditemukan pada insang, lambung, dan usus ikan nila, sedangkan sebanyak 411mikroplastik pada insang, lambung, dan usus ikan layang. Jumlah mikroplastik jenis fragmen padainsang, lambung, dan usus ikan mendominasi, berasal dari fragmentasi plastik bahan polipropilendan polietilen. Jenis mikroplastik terbanyak kedua adalah fiber, dikenali dari bentuknya yangpanjang dan menyerupai tali atau benang berasal dari serat jaring serta peralatan rumah tangga.Pada ikan, mikroplastik jenis fiber dapat menggumpal atau membetuk simpul yang dapatmemblokir saluran pencernaan dan menghalangi jalan masuknya makanan. Mikroplastik jenis filmditemukan dengan jumlah yang paling sedikit pada ketiga organ ikan yang di analisis. Jenis inidiidentifikasi sebagai polimer polietilen yang berbentuk lembaran tipis hasil degradasi plastikkemasan, memiliki densitas paling rendah dari tipe mikroplastik lainnya.Microplastics are a type of plastic waste that can contaminate water, soil, plants, animals, and humans. Microplastic waste from freshwater, include industry, agriculture, and anthropogenic activities, can be a source of microplastic pollution in the sea. Tilapia (Oreochromis niloticus) and Indian scad (Decapterus ruselli) are omnivorous fish that live in the water column. Usually, tilapias are cultivated in fresh water while Indian scads are caught directly from the sea. Microplastic identification using stereo microscope found a total of 158 microplastics in the gills, stomach and intestines of tilapia, while as many as 411 microplastics have been found in the gills, stomach, and intestines of scad fish. The number of microplastic fragments in the gills, stomach, and intestines of fish dominates, comes from the plastic fragmentation of polypropylene and polyethylene materials. The second most common type of microplastic is fiber, recognized by its long shape and resembling a rope or thread derived from fiber nets and household appliances. In fish body, fiber-type microplastics can clump together or form knots that can block the digestive tract and block the passage of food. Film type microplastics were found in the least amount from the three fish organs analyzed. This film types are identified as polyethylene and polypropylene polymers in the form of thin sheets from the degradation of plastic packaging. They have the lowest density of other types of microplastic

Waste Skin of Hawaiian Ladyfish (Elops hawaiensis) Utilization as Gelatin Raw Material With Immersion Solution Combination

Bontot from Domas Village, Pontang District, Serang Regency is a fish jelly product. The manufacture of Bontot produces fish skin waste with a percentage of 10% of the whole weight of the fish. This waste can be reduced by applying the concept of zero waste in the processing of bontot which is reused as a raw material in the manufacture of gelatin. This research aims to determine the best NaOH concentration in the manufacture of gelatin from the skin of Hawaiian ladyfish (Elops hawaiensis) and to determine the effect of NaOH immersion on the organoleptic, chemical, and physical qualities of the gelatin. This study used an alkaline solution (NaOH) with a concentration of 0.1%; 0.3%; and 0.5%, which is then followed by a 6% acid solution immersion process. The production of gelatin from the skin of Hawaiian ladyfish was carried out using a one-factor completely randomized design (CRD) with 2 replications (duplo) accompanied by non-parametric analysis which was carried out for organoleptic testing with a hedonic scale using the Kruskal Wallis test. The results showed that the best combination was 0.1% NaOH and 6% HCl with a hedonic value of 3.7 with a whitish-yellow color; odor hedonic value 3.13; 11% yield; gel strength 280.43 g bloom; viscosity 36.95 cP; water content 8.75%; ash content 0.58%; and a pH value of 6.88</p

KARAKTERISASI KITOSAN KOMBINASI CANGKANG KERANG HIJAU (Perna viridis) DAN CANGKANG RAJUNGAN (Portunus pelagicus) ASAL BANTEN, INDONESIA

Green mussel shells (Perna viridis) and crab shells (Portunus pelagicus) have not been optimally utilized. It’s can be used as chitosan. Chitosan from green mussels has a low degree of deacetylation, so it needs to be combined with crab shells in its manufacture. The aims of this study were to characterize and determine the best combination of raw materials for making chitosan from green mussel shells and crab shells. The method in this study used a completely randomized design with triplicate. The treatment in this study was a combination of raw materials from green mussel shells and crab shells, which were 100:0; 75:25; 50:50% (w/w). The results of this study showed that the combination of green mussel shells and crab shells 50:50% (w/w) resulted the best characterization of chitosan with a yield 12.56%, water content 7.55%, ash content 1.59%, degree of deacetylation 73.96% and viscosity of 279 c
