Abstract

Changes in the area and density of mangroves have a major impact on the sustainability of ecosystem functions in coastal areas. This study aims to analyze changes in the area and density of mangroves in Serang City, Banten. The method used is remote sensing through interpretation of Landsat 5 and Landsat 8 images with analysis of changes in the area and density of mangroves in 2011 and 2021. The research procedure was carried out by grouping NDVI values ​​into 3 vegetation classes: sparse, moderate, and dense. Furthermore, a ground check was carried out to test the level of data accuracy against mangrove canopy cover using the hemispherical photography method. The results showed that the level of image accuracy in 2021 was 90%. Based on this analysis, it is known that there has been a decrease in the area and changes in mangrove density in Sawah Luhur Village, while in Banten Village it has increased. In general, in the coastal area of ​​Serang City, there was a decrease in the mangrove area between 2011-2021 which reached 13.95 ha with the main decrease occurring in mangroves with sparse vegetation class (33.14 ha). In contrast, mangroves with medium and dense density categories increased to 19.19 ha. The decrease in mangrove area was due to abrasion, conversion into ponds, and illegal logging. The results of the analysis also showed that the correlation between NDVI values ​​and the percentage of canopy cover had a value of 0.696 which was included in the strong category.

Abstract

Pengelolaan limbah dalam budidaya udang vaname merupakan aspek penting untuk menjaga keseimbangan antara keberlanjutan produksi perikanan dan pelestarian lingkungan pesisir. Penelitian ini bertujuan untuk menganalisis pengelolaan limbah tambak udang vaname di Kabupaten Pesawaran dari perspektif kelembagaan. Pendekatan yang digunakan meliputi analisis kelembagaan berdasarkan empat dimensi, yaitu situasi, struktur, perilaku, dan kinerja kelembagaan, dengan metode pengumpulan data melalui wawancara mendalam, studi dokumentasi, dan uji kualitas air limbah di laboratorium. Hasil penelitian menunjukkan bahwa pengelolaan limbah di perusahaan ini telah memiliki dasar kelembagaan yang kuat dan selaras dengan regulasi nasional, terutama Keputusan Menteri Kelautan dan Perikanan Nomor 15 Tahun 2022 dan Undang-Undang Nomor 32 Tahun 2009 tentang Perlindungan dan Pengelolaan Lingkungan Hidup. Penerapan Instalasi Pengolahan Air Limbah (IPAL) mampu menurunkan sebagian besar parameter pencemar hingga memenuhi baku mutu lingkungan, seperti pH, DO, TDS, amonia, nitrit, nitrat, dan sulfida. Namun, peningkatan nilai BOD dan phospat menunjukkan perlunya optimalisasi sistem pengolahan limbah organik dan nutrien. Dari sisi kelembagaan, koordinasi antar pemangku kepentingan, pengawasan lingkungan, serta penerapan standard operating procedure (SOP) pengelolaan limbah masih perlu diperkuat untuk mendukung keberlanjutan produksi dan kelestarian ekosistem pesisir.
