Abstract

Coastal areas (especially small islands) are vulnerable to impact from sea level rise (SLR). The submergence of areas that are economic centers will impactin huge losses. To avoid such losses it is necessary to manage small islands by using temporal spatial models. The aim of this article is to describe the development of a temporal spatial model to assess the vulnerability of settlements in small islands. The method used is dynamic system modeling combined with Geographic Information System (GIS) based on identification of environmental issues and conditions in small island, in this case Karimunjawa Island and Kemujan Island, Jepara Regency. The assumption used in the modeling is that there is no natural disaster or calamity that reduces the population, the death is considered normal death by referring to the average life expectancy of the Indonesian population (69 years), no coastal reclamation activities, no significant changes in ecosystem. The modeling results indicate that if the fraction of SLR 10 cm per year, will have an impact on the decreasing availability of settlement land. The height of SLR ranges from 0,5 meters in the 10th year, to 5,0 meters in the 100th year. As a result there will be puddle in the residential area of ​​13,02 ha in the 10th year and in the 100th year to 226,5 ha. Required environmental engineering efforts,such as develop coastal dike and reform plan of building, to reduce impact on the availability of settlement land. SLR that is affecting populations and settlements on Karimunjawa and Kemujan Island, require adaptation as an impact mitigation effort. Wilayah pesisir (terutama pulau kecil) sangat rentan terkena dampak dari peningkatan muka air laut. Terendamnya wilayah-wilayah yang merupakan sentra ekonomi akan mengakibatkan kerugian yang sangat besar. Untuk menghindari kerugian tersebut perlu pengelolaan pulau-pulau kecil dengan memanfaatkan model spasial dinamik/temporal. Tujuan studi adalah mengembangkan model spasial dinamik/temporal untuk mengkaji kerentanan permukiman penduduk di pulau-pulau kecil. Metode yang digunakan adalah pemodelan sistem dinamik/temporal (SD) dipadukan dengan Sistem Informasi Geografis (SIG) berdasarkan identifikasi isu dan kondisi lingkungan di pulau kecil, yaitu Pulau Karimunjawa dan Pulau Kemujan, Kabupaten Jepara. Data yang digunakan adalah data pertumbuhan penduduk (data sekunder) dan peta dasar Pulau Karimunjawa dan Kemujan. Asumsi yang digunakan pada pemodelan adalah tidak terjadi bencana alam atau musibah yang mengurangi jumlah penduduk, kematian dianggap sebagai kematian normal dengan mengacu umur rata-rata harapan hidup penduduk Indonesia (69 tahun), tidak ada kegiatan reklamasi pantai, tidak ada perubahan ekosistem secara signifikan. Pemodelan spasial dinamik/temporal mengikuti tahapan sesuai dengan prosedur pemodelan. Hasil pemodelan menunjukkan bahwa bila fraksi sea level rise (SLR) 10 cm per tahun, akan berdampak pada penurunan ketersediaan lahan permukiman. Tinggi kenaikan muka air laut berkisar antara 0,5 meter pada tahun ke-10, hingga mencapai ketinggian kenaikan 5,0 meter pada tahun ke-100. Akibatnya akan terjadi genangan air laut di permukiman penduduk seluas 13,02 ha pada tahun ke-10  danpada tahun ke-100 menjadi 226,5 ha. Diperlukan upaya rekayasa lingkungan, seperti membangun tanggul pantai dan memperbaiki rancangan konstruksi bangunan permukiman, agar dapat mengurangi dampak terhadap ketersediaan lahan permukiman. Kenaikan muka air laut yang berdampak terhadap penduduk dan permukiman di Pulau Karimunjawa dan Kemujan membutuhkan adanya adaptasi sebagai upaya mitigasi dampak.

Abstract

This study aims to determine the relationship between the catch of each effort unit (CPUE) and the effort to catch fish resources in the coastal waters of Tegal Regency, based on the data series for the last ten years (2011-2020) with survey and interview research methods. The results showed that the existing conditions of fishing effort during the previous ten years had decreased by an average of 1.66 %. The production of fish caught and CPUE landed in Larangan Coastal Fishing Port, Tegal Regency, shows an average increasing trend of 10.91 % and 11.98 %, respectively. The calculation of the relationship between CPUE and effort provides information for MSY of 1,002.24 tons/year, TAC of 801.79 tons/year, with a utilization rate of 120.08 %. Based on the calculation data, it indicates that the average exploitation of fish resources in the coastal waters of Tegal Regency is 962.80 tons/year, which is still below the MSY (1,002.24 tons/year) but has already exceeded the TAC (801.79 tons/year) utilization rate of 120.08 %.

Abstract

Information on distribution and community structure of demersal fish resources are important to be known as an input to the management of demersal fisheries. This study aimed to analyze the diversity and distribution of demersal fish resources based on the differences in the depth of the waters and the linkages to the environment. Research conducted in the South China Sea in May to June 2015 by operating a trawl gear in the station preset. The method of analysis of demersal fish diversity use some ecological indices i.e Margalef species richness index, Shannon-Wiener diversity index, Pielou evenness index, and Simpson dominance index. The ecological index value then associated with environmental conditions, using principal component analysis. Distribution of the ecological index indicated the stability of communities demersal fish resources getting better with the increase of depth. The most affected to the level of species richness and distribution of demersal fish were the parameters of depth, temperature and salinity, while the abundance distribution of fishes were associated with dissolved oxygen, and water transparency. The implication, that the water environmental conditions greatly affected the distribution and abundance of demersal fish. Abstrak Informasi mengenai persebaran dan struktur komunitas sumber daya ikan demersal penting sebagai bahan masukan untuk pengelolaan perikanan demersal. Penelitian ini bertujuan untuk menganalisis tingkat keanekaragaman dan persebaran sumber daya ikan demersal berdasarkan perbedaan kedalaman perairan, serta keterkaitannya dengan lingkungan. Penelitian dilaksanakan di Laut Cina Selatan pada bulan Mei sampai Juni 2015 dengan mengoperasikan alat tangkap pukat ikan di stasiun yang telah ditetapkan. Metode analisis keanekaragaman hayati ikan demersal menggunakan beberapa indeks ekologi yaitu indeks kekayaan jenis Margalef, indeks keanekaragaman Shannon-Wiener, indeks keseragaman Pielou, dan indeks dominansi Simpson. Nilai indeks ekologi tersebut kemudian dikaitkan dengan kondisi lingkungan, menggunakan analisis komponen utama. Hasil penelitian menunjukkan tingkat kestabilan komunitas sumber daya ikan demersal semakin baik seiring dengan meningkatnya kedalaman. Kedalaman, suhu, dan salinitas merupakan parameter yang paling memengaruhi tingkat kekayaan jenis serta persebaran sumber daya ikan demersal, sedangkan persebaran kelimpahan ikan sangat terkait dengan oksigen terlarut dan kecerahan perairan. Implikasinya, kondisi lingkungan perairan sangat memengaruhi persebaran dan kelimpahan ikan demersal.

Abstract

The need for fisheries resources as a source of animal protein encourages the development of capture fisheries businesses. Not infrequently a fishing business in the field of shipping due to lack of care and work cause human souls to become victims. The spirit of the fishermen to go to sea is the main indicator in increasing capture fisheries production in Karawang Regency. However, it is very unfortunate that this was not followed by the awareness of the fishermen about the dangers of working at sea without using personal safety equipment. Therefore, the Karawang Polytechnic of Maritime Affairs and Fisheries Study Program provides training to fishermen on the importance of safety in shipping. As a form of realization of the contents of the Tridarma of Higher Education and the social responsibility and professionalism of a Higher Education in community empowerment towards equitable development. Socialization of Occupational Safety on Fishing Vessels in Karawang Regency is carried out by lecture, question and answer, and demonstration methods. The training materials provided include positioning exercises and anchoring maps with sea charts in Karawang waters, training in the use of map anchoring equipment sets for shipping, training in the use of red hand flares for safety in emergency conditions, training in the use of parachutes signals for safety in emergency conditions, training in the use smoke signal for safety in emergencies, training in the use of lifebuoys for safety in shipping, and training in the use of life jackets. This community service activity was attended by 15 fishermen who live in Karawang Regency.Abstrak: Kebutuhan akan sumberdaya perikanan sebagai salah satu sumber protein hewani mendorong pengembangan usaha perikanan tangkap. Tidak jarang suatu usaha perikanan dibidang perkapalan karena kurang teliti dalam perawatan dan pekerjaannya mengakibatkan jiwa manusia menjadi korban.

Abstract

Handline is a fishing gear that is selective about the catch and is a fishing gear that is passive or in the process of catching it there is a waiting period. The waiting period for the handline is the time when the bait is waiting for the fish to eat it. The depth of the hook on KM Viona III varies. The depth is divided into 2 groups between 45-60 m and 67.5-82.5 m. The purpose of this study was to determine whether or not there was an effect of differences in hook depth on catches by paired sample test t-test using SPSS 24. Based on the Wilcoxon test, non-parametric test hook depth test for total catches presented by SPSS 24 with asymp values .sig of 0.041. Because 0.041 < 0.05 means that there is a difference in catches based on the number of fish and it can be concluded that there is also an effect of hook depth on the number of catches, and the weight of the catch has a value of 0.023. Because the value is 0.023 <0.05, H0 is rejected and Ha is accepted, which means that there are differences in the weight of the catch at different depths and it can be concluded that there is also an effect of the depth of the hook on the weight of the catch. which was carried out at the Cilacap Ocean Fishing Port and participated in a 32-day arrest operation at KM Viona III.
