Abstract

Urban lakes are critical in flood mitigation, providing fresh water, and offering green spaces in urban environments. However, many urban lakes face increasing ecological pressures from various human activities. This study assesses the water quality and morphometric conditions of three urban lakes—Dori, Walini, and Dora in the Cibinong Botanical Garden Complex in Bogor Regency, located in a high-rise residential area. The study aims to evaluate the current water quality, identify contributing factors to water quality degradation, and compare conditions across the three lakes. Data was collected between January and April 2023, utilizing a Geographic Information System (GIS) for morphometric analysis and water quality measurements. Water quality was assessed in accordance with the standards set by Government Regulation No. 22 of 2021. Results indicate that Lake Dori, Walini, and Dora have surface areas of 3,406.96 m², 7,668.37 m², and 13,599 m², respectively. Based on water quality classifications, both Lake Walini and Lake Dori meet Class III standards (suitable for water use), while Lake Dora, though also in Class III, exhibits milder pollution indicators. These findings provide important insights for managing urban lakes and can guide future environmental policies.

Abstract

Muara - muara sungai di Teluk Banten merupakan daerah penangkapan ikan diantaranya adalah muara sungai Cibanten, Wadas, Cengkok dan Pamong. Aktivitas manusia yang padat di muara - muara sungai tersebut dapat mengancam kondisi perairan dan dikhawatirkan dapat mempengaruhi hasil tangkapan ikan. Tujuan penelitian ini untuk mengetahui kualitas perairan di muara  - muara sungai di Teluk Banten apakah sesuai dengan kondisi ideal untuk kehidupan biota ikan. Penelitian dilakukan di muara sungai Cibanten, Wadas, Cengkok dan Pamong. Pengukuran kualitas air dilakukan  pada bulan April 2021 dan hasilnya dibandingkan dengan hasil penelitian di bulan Mei, Juli dan Oktober tahun 2013. Contoh air diambil secara komposit dari permukaan, kedalaman sechi dan dasar perairan. Analisis kualitas air yang dilakukan adalah parameter suhu air, pH, oksigen terlarut, kapasitas oksidasi reduksi, kekeruhan, Total Padatan Terlarut, Total Padatan Tersuspensi, Salinitas, N-NO2, N-NO3, N-NH4, P-PO4, Total N, Total P, Logam Fe, Cr dan Pb serta klorofil -a. Hasil analisis yang didapat dibandingkan dengan baku mutu air laut.  Hasil analisis umumnya masih memenuhi baku mutu kecuali beberapa parameter seperti TSS dan kondisinya sama seperti tahun 2013. Hal ini harus menjadi perhatian serius untuk diatasi agar perikanan tangkap di muara – muara sungai di Teluk Banten tetap lestari.
