Abstract

Cibanten watershed upstream is from Karang Mount (one of that is shallow lake Cibanten water springs), flow in Serang City and the downstream at Banten Bay. From upstream until downstream, Cibanten watershed used by various anthropogenic activities where potentially to increasing trophic state of the waters. This research aimed to evaluate trophic state of Cibanten watershed. Research conducted at April – Mei 2018. Water sample took and measured at three different location, upstream (code: Hu), Central (code: T) and downstream (code: Hi). Water parameters where in-situ measurement was water depth, temperature, secchi depth, water colour, pH, dissolved oxygen and salinity (special for downstream). Water sample analysed at Aquaculture Laboratory of UNTIRTA, the water parameter was phosphate and chlorophyll-a. Trophic state of Cibanten watershed analysed with Trophic State Index (TSI). The result from upstream of Cibanten watershed categorized as mesotrophic, with maximum secchi depth until water bottom and existed some water plant. In the central and downstream of Cibanten watershed categorized as light eutrophic. The significant different between upstream, central and downstream of Cibanten watershed is secchi depth. Low secchi depth at central and downstream due to water turbidity, shown by water colour is yellowbrown that assumed come from suspended solid contents.

Abstract

Fish apartment is a hollow building composed of solid objects placed in waters which is intended to replace the ecological function of natural habitat for fish resources. Therefore, the placement of fish houses must be done taking into account certain criteria. The aim of this research is to determine the suitability of the location for placing fish apartment in the waters of Kalih Island, Serang Regency, Banten Province. Survey and data collection activities were carried out in November 2023. The data collected included oceanographic characteristics, water quality and existing utilization activities carried out by the community in the waters of Kalih Island. Location suitability analysis is carried out using a scoring method with certain criteria. The results show the waters of Kalih Island are not suitable for placing fish apartment with the final scores obtained being 210 and 220. Parameters that are less suitable include water brightness, substrate type, safety factors and low community participation.

Abstract

Daerah pantai yang dinamis memberikan respons terhadap peristiwa ekstrem salah satunya adalah kenaikan muka air laut. Hal tersebut akan memberikan dampak buruk pada kondisi wilayah pesisir, seperti pada Pantai Binuangeun yang sekarang ini mengalami abrasi akibat adanya hantaman gelombang besar. Hal ini menunjukkan wilayah pesisir Lebak berpotensi mengalami kerentanan, terutama akibat kenaikan muka air laut. Penelitian ini bertujuan untuk memetakan sebaran kerentanan wilayah Pesisir Kabupaten Lebak Banten terhadap kenaikan muka air laut. Metode yang digunakan dalam penelitian ini adalah Coastal Vulnerability Index (CVI). Data yang dikumpulkan terdiri dari data primer yang diperoleh dengan melakukan observasi lapangan dan data sekunder yang diperoleh melalui NOAA, Copernicus, dan IOC Sea Level Monitoring. Variabel kerentanan yang dianalisis adalah geomorfologi, perubahan garis pantai, elevasi, kenaikan muka air laut, tunggang pasang surut, dan tinggi gelombang. Karakteristik pantai Lebak adalah karang, berpasir, dan tebing. Penilaian kerentanan dibagi menjadi 3 kelas, yaitu rendah, sedang, dan tinggi. Hasil penelitian menunjukkan bahwa nilai Coastal Vulnerability Index (CVI) pesisir Lebak berkisar antara 2,9-2,19. Nilai tersebut menunjukkan seluruh kecamatan pesisir Kabupaten Lebak termasuk dalam kategori kerentanan rendah terhadap kenaikan muka air laut. Oleh karenanya pesisir Lebak tidak berpotensi terdampak bencana-bencana yang diakibatkan oleh kenaikan muka air laut.
