Abstract

This research aims to analyze the quality of marine waters in the Saugi Island area, North Liukang Tupabbiring District, Pangkep Regency, and its impact on marine biota. This research uses a descriptive quantitative approach by processing data from field measurements and laboratory tests on several parameters. Furthermore, the test results will be compared with the standard requirements for seawater quality for the needs of marine biota by referring to the Decree of the Minister of the Environment No. 51 of 2004. In addition, a spatial analysis is carried out to see the predicted concentration distribution pattern for each measurement parameter. each of these parameters. The research results show that of the 10 research stations, only station 4 meets several seawater quality standards. The presence of waste at each station plays a significant role in reducing the value of quality parameters. In conclusion, the quality of seawater on the coast of Saugi Island is not good for marine biota. Therefore, efforts are needed to maintain the cleanliness of the coastal environment so that air quality is maintained, supports the life of marine biota, increases catches, and the potential for sustainability of marine ecosystems.

Abstract

ABSTRACT Drought is a hydrometeorological disaster that has a major impact on water availability and agricultural sustainability. This study maps drought vulnerability levels in Gowa Regency using a Geographic Information System–based weighted overlay method with seven parameters, namely rainfall, soil type, slope, elevation, distance from rivers, land use, and vegetation density, which were analyzed through weighting techniques and equal interval classification in ArcGIS 10.3. The results show that the study area is divided into five vulnerability classes: very low (6.10%), low (33.48%), moderate (39.31%), high (17.76%), and very high (3.35%), with spatial patterns varying across districts. Most areas fall within the low to moderate vulnerability categories, while high vulnerability is mainly found in wetland and dryland agricultural zones that experience high pressure on water use. These findings indicate that the weighted overlay–based geospatial approach is effective in depicting the spatial distribution of drought vulnerability and can serve as a basis for water resource management planning, risk mitigation, and strengthening food security in Gowa Regency. ABSTRAK Kekeringan merupakan bencana hidrometeorologi yang berdampak besar terhadap ketersediaan air dan keberlanjutan pertanian. Penelitian ini memetakan tingkat kerawanan kekeringan di Kabupaten Gowa menggunakan metode weighted overlay berbasis Sistem Informasi Geografis dengan tujuh parameter, yaitu curah hujan, jenis tanah, kemiringan lereng, ketinggian, jarak dari sungai, penggunaan lahan, dan kerapatan vegetasi yang dianalisis melalui teknik pembobotan dan klasifikasi equal interval pada ArcGIS 10.3. Hasil analisis menunjukkan bahwa wilayah penelitian terbagi ke dalam lima kelas kerawanan, yaitu sangat rendah (6,10%), rendah (33,48%), sedang (39,31%), tinggi (17,76%), dan sangat tinggi (3,35%) dengan pola spasial yang bervariasi antar kecamatan. Sebagian besar wilayah berada pada kategori rendah hingga sedang, sementara tingkat kerawanan tinggi terutama ditemukan pada kawasan pertanian lahan basah dan lahan kering yang memiliki tekanan penggunaan air yang besar. Temuan ini menunjukkan bahwa pendekatan geospasial berbasis weighted overlay efektif untuk menggambarkan distribusi kerawanan kekeringan dan dapat dimanfaatkan sebagai dasar perencanaan pengelolaan sumber daya air, mitigasi risiko, dan penguatan ketahanan pangan di Kabupaten Gowa.
