Abstract

Indonesia is an Archipelago Country because the Country of Indonesia consists of many islands stretching from Sabang in the west to the island of Merauke on the east. The Archipelago Country also comes from the old name of the Indonesian Country called Nusantara, because Nusantara is a country that consists of many islands. Indonesia is an Archipelago Country which means it has potential resources in the coastal areas, one of which is found on the northern coast of Java. The coastal area is an important area to be reviewed, one of which is the use of coastal resources by paying attention to the condition of the ecosystem that remains stable. Opportunities for coastal area utilization in the field of fisheries are in the form of fishing activities or fish farming, especially pond cultivation activities. Based on data from the Department of Marine and Fisheries of the Province of Central Java in 2010, pond cultivation is one of the potential resources on the coast. This potential is supported by the government to increase fish production in order to increase the consumption of fish in the community. Therefore, it is necessary to choose the most effective method of pond cultivation between traditional methods and intensive methods to optimize fish production. One indicator of effectiveness between the two methods can be seen from the phytoplankton distribution. Phytoplankton contains chlorophyll-a in the body and is a natural food from fish. Phytoplankton provides important ecological functions for the aquatic life cycle by serving as the basis of food webs in water. Phytoplankton also functions as the main food item in freshwater fish culture and seawater fish cultivation. Therefore, it is necessary to know the chlorophyll-a concentration in the ponds of traditional and intensive methods to determine the concentration chlorophyll-a of the two pond methods. One method used to determine the concentration of chlorophyll-a using remote sensing technology. Remote sensing technology can be used to determine the concentration of chlorophyll-a using the Wouthuyzen, Wibowo, Pentury, Much Jisin Arief and Lestari Laksmi algorithms. The results showed that the Pentury algorithm was relatively better to determine the concentration of chlorophyll-a in shallow waters (ponds). The lowest concentration of chlorophyll-a in traditional ponds is 0.47068 mg/m3, the highest concentration is 1.95017 mg/m3 and the average concentration is 1.12893 mg/m3, while in intensive ponds the lowest concentration is 0.36713 mg/m3, the concentration the highest is 3.17063 mg/m3 and the average concentration is 1.53556 mg/m3.

Abstract

DAS Serayu merupakan salah satu dari 108 DAS yang ditetapkan sebagai DAS prioritas pada tahun 2020 – 2024 dikarenakan mengalami penurunan daya dukung. Penurunan daya dukung tersebut salah satunya ditandai dengan peristiwa erosi yang disebabkan oleh aktivitas eksploitasi lahan di bagian hulu DAS Serayu terutama di Sub DAS Serayu Hulu. Penelitian ini dilakukan untuk memberikan informasi mengenai persebaran laju erosi di Sub DAS Serayu Hulu pada tahun 2022 menggunakan metode Universal Soil Loss Equation (USLE). Penentuan laju erosi tersebut memanfaatkan Sistem Informasi Geografis (SIG) berbasis raster dengan menggunakan lima parameter meliputi erosivitas hujan (R), erodibilitas tanah (K), panjang dan kemiringan lereng (LS), pengelolaan tanaman (C) dan tindakan konservasi lahan (P). Hasil penelitian menunjukkan bahwa Sub DAS Serayu Hulu memiliki nilai laju erosi terendah sebesar 0,0169 ton/ha/tahun dengan tutupan lahan sawah di Kecamatan Selomerto sedangkan nilai laju erosi tertingginya sebesar 5.842,6042 ton/ha/tahun yang berada pada tutupan lahan pemukiman di Kecamatan Kejajar. Sub DAS Serayu Hulu didominasi oleh laju erosi >15-60 ton/ha/tahun dimana termasuk ke dalam kelas tingkat bahaya erosi ringan dengan luasan sebesar 5091,359 ha atau sekitar 36,96% dari total luas sub DAS Serayu Hulu. Laju erosi >480 ton/ha/tahun yang masuk ke dalam kelas tingkat bahaya erosi sangat berat memiliki luasan paling kecil sebesar 928,906 ha atau 6,74%.
