<p><em>The existence of the coast in the northern part of Karawang Regency is very worrying. Seawater<strong> </strong>that was far up to tens of meters from the side of the road, is now on the lip of the road, even some parts of the road are cut off due to abrasion of seawater. Some villages were affected by abrasion erosion. One of the effects of damage due to abrasion and sedimentation is the occurrence of shoreline changes. This change in coastline will affect people's lives and spatial planning for the development of the area. For this reason, this study aims to determine the extent and rate of shoreline changes that occurred on the coast of Karawang Regency in the periods of 1989, 1995, 2001, 2005, 2009, 2016, and 2018. The shoreline data was obtained from the extraction of Landsat 3 MSS, Landsat 5 TM, Landsat 7 ETM +, and Landsat 8 </em><em>OLI</em>-<em>TIRS after the NDWI process was previously carried out. While the rate of change is calculated at 6 sample point locations scattered along the northern coast of Karawang Regency. The results showed that the largest area damaged by abrasion occurred in Sedari Village covering an area of 166.802 hectares, and the area formed by the largest sedimentation occurred in Muara Cilamaya Village at 276,318 hectares. Meanwhile, the fastest rate of shoreline change due to abrasion occurred in Sukajaya Village at 10 meters </em>/<em>year, while the slowest in Sedari Village at 3.77 meters / year. The fastest sedimentation process in Muara Cimalaya Village is 4.5 meters / year, while the late one in Tanjung Pakis Village is 3.09 meters / year.</em><em></em></p><p><strong><em>Keywords: </em></strong><em>Abra</em><em>sion, Accretion, Coastline Changes, Karawang</em><em></em></p>

Perikanan teri berkembang sangat pesat khususnya di perairan utara Jawa Madura pada tahun terakhir ini. Kajian tentang karakteristik perikanan teri (Engraulidae) di sepanjang pantai utara Jawa-Madura dilaksanakan pada tahun 2017-2018, meliputi sebaran usaha perikanan, tipe armada-alat penangkapan ikan, aspek operasional penangkapan, hasil tangkapan-kelimpahan dan musim penangkapan ikan teri. Pengumpulan data pendaratan ikan teri dilakukan melalui survey di 11 lokasi pendaratan ikan. Hasil penelitian menunjukkan terdapat 12 lokasi tempat pendaratan utama ikan teri di sepanjang pantai utara (pantura) Jawa dan Madura. Dua jenis alat dominan digunakan untuk penangkapan teri adalah pukat cincin dan payang; perikanan bersifat skala kecil, melakukan trip harian, dengan armada kapal penangkap berukuran dibawah 20 GT. Jaring umumnya menggunakan waring dengan mata jaring kecil (3/8 inch) di bagian kantong. Daerah penangkapan di perairan pantai yang dangkal, dekat dengan basis perikanan. Musim penangkapan ikan teri bervariasi, di wilayah bagian barat (Pulolampes, Larangan, Morodemak) berlangsung sekitar musim timur/tenggara (Mei Juli), sedangkan di wilayah bagian timur berlangsung pada awal musim timur dan berjalan cukup lama hingga bulan November (musim peralihan 2). Hasil tangkapan per unit upaya (CPUE, sebagai indek kelimpahan) diduga makin ke arah timur semakin rendah namun disertai musim penangkapan ikan lebih lama. Anchovy fishery has grown rapidly, especially in the northern waters of Java-Madura in the last year. The study on the characteristics of the anchovy fishery (Engraulidae) along the northern coast of Java-Madura was carried out in 2017-2018, covering the distribution of fisheries effort, types of fishing gear, operational aspects of fishing, catch-abundance and fishing season. The collection of anchovy landing data was carried out through a survey at 11 fish landing sites. The results showed that there were 12 main anchovy landing sites along the north coast (pantura) of Java and Madura. Two types of dominant fishing gear used for anchovies are purse seine and payang; Fisheries are small-scale, undertaking daily trips, with a fleet of fishing vessels under 20 GT. The nets generally use “waring” with small mesh (3/8 inch) in the codend. Fishing area in shallow coastal waters, close to the fishing base. The fishing season for anchovy varies, in the western region (Pulolampes, Larangan, Morodemak) it takes place around the east / southeast season (May-July), while in the eastern region it takes place at the beginning of the eastern season and lasts quite a long time until November (transition season 2) . The catch per unit effort (CPUE, as an abundance index) is thought to be getting lower eastward but accompanied by a longer fishing season.

Shoreline changes, that occur along the coast, gives negative effects to the environment and also social-economic activities on the fishermen’s livelihood. Study about shoreline changes, its trends, and its causes are important for the development of economic and sanitation vulnerability assessment on fishermen community caused by shoreline changes. Thus, environmental sustainability criteria within the local scale and specific to fishermen community takes into account and the implementation of the instrument become more appropriate to reduce the undesirable effects. This research aims to identifying and analysing shoreline changes trend and its factors over the fishermen settlement area along the coast of Sungaibuntu and Cemarajaya village, Karawang Regency, West Java. Data used in this study are Landsat-7 1999, 2002, 2007, and 2012 as well as Landsat-8 2017. To enhance Landsat-7 images, band 2-4-5 are used, meanwhile Landsat-8 employs band 3-5-6. Later, the shoreline was extracted by applying band rationing techniques, Band2/Band5 for Landsat-7 and Band3/Band6 for Landsat-8. The rate of shoreline changes along the coast of Sungaibuntu is -0.15 m/yr and -2.89 m/yr along Cemarajaya. The periodic phenomena that affect shoreline changes consist of tidal range with a mean value of 0.796 m, significant wave height (Hs) of 0 - 2.9 m with the dominant direction heading to the southeast, and also sea level rise (SLR). Besides, there is an anthropogenic factor of land use and land cover changes as the significant feature shown by the managed system of ponds, cropland, farmland, paddy field, along with the settlement. As for the instrument development of economic and sanitation vulnerability on fishermen community, it is important to take shoreline changes rate and its causes into account and consider it as vulnerability criteria.

Abstract Data on the deep sea fishes found off the northern Brazilian coast are restricted to the results of the surveys of the RV Oregon, a research vessel of the North American National Marine Fisheries Service, and the REVIZEE Program. The REVIZEE Score-Norte Program focused on commercial fish species and natural resources with potential for exploitation on the continental shelf and slope off the northern coast of Brazil. In this sense, the REVIZEE Score-Norte Program generated little information on species of no commercial value, did not catalog its inventory in zoological collections, and did not publish species lists. Given this considerable knowledge gap on the deep-sea fish found off the North coast of Brazil, we compiled all the available data on the deep-sea fish of this region and also retrieved photographic records from the REVIZEE Score-Norte Program, including the PRODEMERSAL and PROTUNA projects. Considering the published records, specimens deposited in zoological collections, and the interpretation of photographic records, we compiled a list of 63 species of deep-sea fish from the North coast of Brazil. An additional 30 species were found in the published records from the PRODEMERSAL and PROTUNA, but were considered to be doubtful or pending confirmation.

Penelitian ini dilakukan untuk memperoleh informasi tentang perubahan garis pantai dan kaitannya dengan tutupan lahan di pesisir Desa Surodadi Kecamatan Sayung Kabupaten Demak pada tahun 2015 dan 2016. Penelitian ini dilaksanakan pada bulan Mei sampai dengan Juni 2017. Stasiun penelitian dibagi menjadi lima stasiun berdasarkan lokasi abrasi dan akresi yang telah terjadi. Dengan proses overlay kedua data citra satelit melalui sistem informasi geografis merupakan cara cepat untuk mengetahui perubahan garis pantai yang terjadi pada pesisir Desa Surodadi. Metode penelitian ini dengan menggunakan metode deskriptif studi kasus dengan menggunakan teknologi penginderaan jauh pada pengolahan data citra SPOT 6 tahun 2015 dan tahun 2016 yang diperoleh dari Pusat Teknologi dan Data Penginderaan Jauh LAPAN Jakarta serta dilakukan survei lapangan sehingga diperoleh laju perubahan garis pantai serta tutupan lahan yang terdapat pada lokasi penelitian. Garis pantai yang terjadi dari tahun 2015 sampai tahun 2016 lebih banyak mengalami proses abrasi jika dibandingkan proses akresi. Berdasarkan hasil penelitian dapat diketahui laju perubahan panjang garis pantai sebesar 103,58 m, perubahan garis pantai yang terjadi berupa abrasi sebesar 1,197 ha dan perubahan yang berupa akresi sebesar 0,490 ha. Keterkaitan antara perubahan garis pantai dengan tutupan lahan di Desa Surodadi adalah tutupan mangrove yang ada cukup luas dan relatif rapat sehingga dapat mencegah intrusi air laut yang dapat menyebabkan perubahan garis pantai. Surodadi village coastline changes from year to year. This serious change is necessary for ongoing monitoring. This research was conducted to obtain information about coastline change and its relation to land cover in coastal village of Surodadi Sub-District of Sayung Regency of Demak in 2015 until 2016. This research was conducted from May to June 2017. The research station is divided into five stations based on the location of abrasion and Accretion that has occurred.

Salah satu alasan yang kuat nelayan tangkap skala kecil tetap melaut meskipun mempunyai risiko tinggi karena peluang/prospek pendapatan/penerimaan yang tinggi pada satu saat. Risiko melaut tidak hanya membuat ketidakpastian tetapi juga karena risiko biaya operasional yang tinggi. Dihadapkan dengan kondisi biaya operasional yang  tinggi, nelayan menggunakan strategi yang berbeda, salah satunya melekat pada peran tengkulak. Dalam pandangan konvensional, pedagang perantara/ langgan sebagai hambatan bagi nelayan untuk menjadi kompetitif di pasar. Namun di negara berkembang seperti Indonesia, mereka memainkan peran penting sebagai "bantal sosial" dalam kehidupan nelayan skala kecil. Tujuan penelitian adalah menyelidiki tingkat kecenderungan keterikatan hubungan langgan/pedagang antara sebagai “bantal sosial” dengan nelayan di dua daerah penangkapan ikan yang menonjol di pantai utara dan pantai selatan Jawa. Analisis data dilakukan dengan metode analisis kuantitatif yaitu model analisis multinomial logistik. Hasil penelitian menunjukkan bahwa nelayan dari pantai utara cenderung sangat kuat hubungannya dengan perantara untuk kelangsungan hidupnya dibandingkan dengan nelayan di pantai selatan. Implikasi dari temuan tersebut bahwa peran sentral langgan/perantara/tengkulak/langgan merupakan bentuk hubungan yang bersifat ekonomi dimana kedua belah pihak bisa mengambil keuntungan. Pola hubungan bukan hanya sekedar sebagai penyangga, namun lebih dari itu yaitu berfungsi sebagai “bantal” sosial (social cushion) para nelayan. Hubungan seperti ini merupakan bentuk layanan dimana para nelayan bisa mendapatkan alternatif layanan jasa “kredit” dari para perantara/langgan/tengkulak. Bentuk layanan seperti yang diperankan oleh langgan/pedagang perantara selama ini belum bisa digantikan oleh lembaga pemerintah yang resmi, dimana pola hubungan tersebut sangat dibutuhkan oleh nelayan skala kecil. Pola hubungan tersebut selain dipengaruhi oleh lokasi, juga dipengaruhi oleh status kepemilikan kapal, lama kepemilikan kapal dan jumlah ABK.Title: The Role “Social Cushion” On The Livelihood Of Small Scale Fishers In JavaOne of the strong reason for small scale fishers to keep fishing despite high risk of fishing, is the prospect of high earning at one moment in time. Risk at fishery not only  create uncertaining but also risk high cost of fishing. Faced with such a high cost, fishers use different strategies, one of which is attached to the middlemen. Convientional views middlemen as an obstacle for fishers to be competitive in the market. Yet in developing country such us Indonesia, they play crucial role as a “social cushion” in the livelihood of small scale fishers. The purpose of research is to investigate the tendency of engagement relationships middleman as "social cushion" with fishermen in the fishing areas that stand out on the north coast and the south coast of Java. Data was analyzed using quantitative analysis method multinomial logistic analysis model. Results of this study show that fishers of the northern coast tend to strongly attach to middlemen for their survival compared with those in the southern coast.  Relationships with fishermen middlemen is a service, where fishermen can get alternative services "credit" from the middleman. Services such as that played by middleman has not been able to replace them by official government agencies, where this kind of relationship is needed by small-scale fishermen. The relationship patterns in addition affected by the location, also influenced by the status of ownership of the vessel, long time ship ownership and the number of crew.
