Abstract

This research aims to analyze the correlation between sea surface temperature with seagrass bed in Pramuka Island, Kepulauan Seribu Regency. The observation to obtain the primary data which held on December 7th, 2019, was done through direct surveillance of existing seagrasses, and by doing some interviews with locals. Information from books, journals, reports, and satellite images are used as secondary data. Both data were processed with analytics description method to conclude the result. The finding shows that Pramuka Island has the optimal temperature for seagrass development. While temperature plays a crucial role in seagrass physiology and biomass production, there are other numerous environment and anthropogenic factors that affect seagrass distribution and quality. Furthermore, the local community activities are also affecting the seagrass ecosystem, especially those activities in the economic sector such as tourism and construction. Therefore, education on the importance of maintaining seagrass ecosystems will be needed by both local residents as well travelling tourists.

Abstract

There were 21 landslides in Citeureup Subdistrict in 2017-2021 which caused several houses to be slightly damaged to severely damaged, and road and bridge infrastructure was cut off. This study aims to identify landslide-prone areas in Citeureup Sub-District. The method used was descriptive method with a spatial approach. Data was processed using GIS 10.8 software with the analytical technique used was a spatial analysis by overlaying five parameters of landslide susceptibility. After that, field validation was carried out. The subjects in this study were 12 selected land units. The results showed that areas that are included in the category of low landslide prone are Citeureup, Leuwinutug, Puspanegara, Puspasari, Sanja, and West Karangasem and East Karangasem Villages. The distribution of areas in the landslide-prone category is in a small part of Hambalang Village, Sanja, East Karangasem Village, and Leuwinutug Village. The distribution of areas in the high landslide-prone category is in most of Hambalang, Tajur, and Tangkil Villages. The distribution of areas in the landslide-prone category is very high in most of Hambalang, Tangkil, Sukahati, and a small part of it in East Karangasem Village. The distribution of landslide-prone areas is dominated by areas in the high landslide-prone category. Meanwhile, the distribution of landslide-prone areas is at least found in the medium landslide-prone category area.
