Keterkaitan Tata Guna Lahan terhadap Kondisi Indeks Pencemaran di Teluk Jakarta

Abstract

Teluk Jakarta dikelilingi oleh kawasan strategis nasional yang padat aktivitas. Kegiatan antropogenik berpotensi terhadap perubahan tata guna lahan. Adanya aliran sungai berpotensi membawa masukan nutrien ke perairan dan menyebabkan pencemaran. Penelitian ini menjelaskan keterkaitan tata guna lahan terhadap kondisi indeks pencemaran di Teluk Jakarta. Penelitian ini menggunakan data penelitian pada 23 stasiun pengamatan di Teluk Jakarta tahun 2019 dan 2022. Analisis dilakukan terhadap 9 parameter kualitas air, seperti suhu, pH, DO, BOD5, nitrat, fosfat, kekeruhan, TSS, dan total coliform. Tata guna lahan di sekitar Teluk Jakarta tidak mengalami perubahan yang besar. Perubahan ini juga tidak secara besar memengaruhi perubahan nilai setiap parameter indeks pencemaran. Indeks pencemaran di Teluk Jakarta pada tahun 2019 dan 2022 secara umum berstatus tercemar ringan. Kondisi indeks pencemaran tidak secara signifikan dipengaruhi oleh tata guna lahan di sekitar Teluk Jakarta, tetapi juga dipengaruhi oleh aktivitas antropogenik di daerah hulu sungai (up land).

Jakarta Bay is surrounded by a national strategic area that is full of activity. Anthropogenic activities have the potential to change land use. The existence of a river flow has the potential to bring nutrient inputs into the waters and cause pollution. This study explains the interconnectedness between land use and pollution index conditions in Jakarta Bay. This study used research data from 23 observation stations in Jakarta Bay in 2019 and 2022. Analysis was carried out on 9 water quality parameters, such as temperature, pH, DO, BOD5, nitrate, phosphate, turbidity, TSS, and total coliform. The land use around Jakarta Bay has not changed significantly. This change also does not significantly affect changes in the value of each pollution index parameter. The pollution index in Jakarta Bay in 2019 and 2022 is generally lightly polluted. The condition of the pollution index is not significantly affected by land use around Jakarta Bay, but is also influenced by anthropogenic activities in the upland area.
