Abstract

Dinamika oseanografi pantai Karawang sangat dipengaruhi oleh gelombang dari Laut Jawa. Proses hidro-oseanografi ini menyebabkan kerusakan di beberapa tempat di Pantai Utara Karawang. Penyebab kerusakan yang paling utama adalah gelombang laut yang datang dari arah timur laut. Gelombang ini menyebabkan adanya arus sejajar pantai dan tegak lurus pantai yang menyebabkan terjadinya abrasi dan sedimentasi pantai. Kerusakan pantai dapat dicegah dengan mendirikan bangunan pengaman pantai. Penelitian ini bertujuan untuk menentukan jenis bangunan pengaman pantai sebagai salah satu cara mencegah kerusakan pantai di pesisir kabupaten Karawang dengan cara mengumpulkan, mengolah dan menganalisis data batimetri, angin dan pasang surut.  Berdasarkan analisis data pasang surut dapat menentukan elevasi bangunan, dari pengolahan data angin diperoleh peramalan gelombang berupa tinggi, periode, dan arah gelombang. Hasil analisis gelombang, batimetri dan topografi, diperoleh bahwa jenis bangunan pantai yang sesuai untuk pengaman pantai di pesisir kabupaten Karawang adalah bangunan breakwater dan groin. Breakwater dan groin dipilih untuk pengaman pantai di pantai Karawang karena dapat mengurangi limpasan gelombang yang terjadi, sehingga dapat melindungi pantai dari gempuran gelombang supaya tidak terjadi abrasi.

Abstract

Sentra perikanan tangkap kota Cirebon, ditunjukkan oleh aktivitas PPN Kejawanan dan tiga TPI lain di sekitarnya. Terdapat 9 Kelompok Usaha Bersama (KUB) yang tumbuh dari aktivitas sub sektor perikanan tangkap kota Cirebon. Penelitian bertujuan menemukan strategi untuk meningkatkan kinerja KUB dalam rangka memberdayakan keluarga nelayan. Metode penelitian deskriptif dengan pendekatan fenomenalogi. Peneliti menggunakan survei terestris untuk melakukan wawancara tertutup dengan responden yang dipilih secara sengaja, mengenai 15 tema yang dianggap merefleksikan aktivitas kebaharian para nelayan. Responden berjumlah 172 orang, memiliki kriteria khusus terutama dari sisi ketokohan, pengalaman, dan keahlian bekerja sebagai nelayan. Hasil penelitian menunjukkan bahwa nelayan kinerja KUB nelayan rendah karena mayoritas terjerat oleh tengkulak. Kinerja KUB hanya dapat ditingkatkan apabila nelayan memiliki komitmen dan konsistensi memberdayakan dirinya; ditandai dengan indikasi berupa meningkatnya kemampuan mengolah dan menghasilkan produk bermutu; serta memiliki dasar pengetahuan yang kuat tentang kebaharian. Bukan sebagaimana saat ini, hal mana nelayan melaut berbekal pengalaman dari hasil meniru pekerjaan yang dilakukan oleh para pendahulu sebelumnya.

Abstract

The existence of the coastline in the northern part of Karawang Regency is very worrying due to abrasion and sedimentation where sea water that was far from the side of the road is now on the edge of the road and several areas along the coast have been damaged affected by the abrasion. The process of abrasion and sedimentation can be monitored by using Remote Sensing technology, which is technology that uses electro magnetic waves to produce images obtained from sensors carried by satellites with the physical properties of objects observed on the surface of the earth. The purpose of this study was to determine the process of abrasion and sedimentation that occurred in the Karawang regency coast by using remote sensing technology. Based on the results of data processing and analysis conducted in 6 sub-districts along the Karawang coast, abrasion and sedimentation have occurred, where 4 villages experienced abrasion while 2 villages experienced sedimentation. The largest area formed due to abrasion occurred in Sedari village covering 166,802 hectares and the largest area formed by sedimentation occurred in Muara Cilamaya village of 276,318 hectares. The fastest speed of abrasion process occurred in Sukajaya village by 10.00 meters / year while the fastest sedimentation process was in Muara Cimalaya village at 4.50 meters / year.

Abstract

The research objective was to determine the effect of the edible coating of crab chitosan on the sensory quality of Betawi dodol. The process of making crab chitosan edible coating starts from mixing chitosan, 1% acetic acid, and glycerol, immersing dodol into edible coating solution, and storage. Edible coating with a concentration of 4% chitosan (K3) can maintain appearance and texture values ​​until day 12 and aroma until day 16, longer than K0 and K1 treatments can only maintain appearance and texture values ​​until day 4 and aroma until the 8th day and K2 which can maintain the appearance and texture values ​​until the 8th day and the aroma until the 12th day and there is no difference in the taste values ​​in the three treatments. Based on the Friedman test, the parameters of appearance, aroma, and texture have a sig. <0.05 so that H1 is accepted and H0 is rejected, which means that the difference in chitosan concentration has a significant effect. Meanwhile, the Friedman taste test has a sig.> 0.05 so that H0 is accepted and H1 is rejected, which means that the difference in chitosan concentration does not have a significant effect.

Abstract

Catfish (Clarias sp.) is a type of freshwater fish that has been widely farmed for generations.  Usually it is consumed as a whole fish or its meat that processed as nuggets, shredded fish, or other products.  The processing of these products produces a by-product in the form of catfish bones which can be used to make fish bone meal. Fish bones have important mineral sources including sodium, phosphorus and calcium. Calcium ion (Ca2+) is important for the development of human bones and teeth, especially in infants. So as to maximize the utilization of fish resources and reduce waste from the fishing industry, the purpose of this study was to determine the sensory and chemical quality of tempeh with the addition of catfish bone meal and to predict the shelf life of tempeh.  The method used in this research is descriptive analysis method. The results of the sensory test with the hedonic test showed that the most preferred tempeh by the panelists was the addition of 2% (F3) bone meal with an appearance value of 7.2, smell/aromatic 6.9, and texture 6.9. Tempe added with 2% fish bone meal had a water content and protein content that complied with the SNI requirements, namely 58.58% and 20.65%, but the water content did not meet the SNI requirements, namely 4.01% and calcium content 142,73 mg/100 gram. Based on the results of the shelf life prediction, tempeh with the addition of fish bone meal was still suitable for consumption at 2 days of incubation because after two days there was an unwanted change in appearance, smell/aroma and texture.

Abstract

The existence of the coast in the northern part of Karawang Regency is very worrying. Seawater 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 OLI-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 /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.

Abstract

The objective of this research is to determine the optimal formulation for fish feed production by utilizing by-products from the swanggi fish (Priacanthus tayenus) surimi process, corn cob flour, and fine bran, considering parameters such as hardness, durability, buoyancy, load resistance, water resistance, buoyancy time, sensory evaluation, and proximate analysis. The study is divided into several stages, namely the production of swanggi fish bone meal, corn cob flour production, and fish feed production using four different formulations based on varying amounts of swanggi fish bone meal: F1 (400 grams), F2 (450 grams), F3 (500 grams), and F4 (550 grams). Quality testing of fish feed includes physical tests for hardness, durability, buoyancy, sensory evaluation, and proximate analysis. Fish feed has been successfully produced using four different formulations, with the best formulation determined through sensory analysis and physical tests, particularly formulation F1. The average value for F1 in terms of shape, odor, and texture parameters is 3.88. The best physical test results for the fish feed product are observed in formulation F1, with hardness not breaking under a 500-gram load, underwater durability lasting for 70 minutes before sinking, and buoyancy lasting for 62 minutes until the feed sinks. The highest proximate content is found in formulation F4, which complies with the SNI 01-7242-2006 standard for tilapia fish feed for rearing and growth, with protein content at 30.29%, fat content at 40.36%, moisture content at 5.25%, ash content at 7.85%, and carbohydrate content at 16.25%.

Abstract

Cuckang fish (Muraenesox cinerus) are widespread in Indonesian waters, have an elongated body shape like an eel. The name of the cuckang fish (Muraensox cinerus) is different in each region, in the Pati area this fish is called "tonang" fish, while in the regions of West Kalimantan, Riau, and the Natuna Islands this fish is usually called "malong" fish. The purpose of this observation was to determine the characteristics of frozen Cangfish fillet products which were processed by applying the Good Manufacturing Process (GMP) and Standard Sanitation Operation Procedure (SSOP). It cannot be denied that fishery products or those made from fish are perishable foods. Therefore, it is necessary to make efforts to increase food safety in order to maintain and maintain the quality of frozen Cang fish fillet products for the safety of consumers.
