Abstract

Abstrak. Perairan Natuna, khususnya pada Kawasan Konservasi Laut Daerah (KKLD) I diprioritaskan untuk mendukung kegiatan perikanan berkelanjutan, sehingga penting diketahui kualitasperairannya. Penelitian ini bertujuan untuk mengetahui karakteristik kualitas air berdasarkan parameter fisika maupun kimia sebagai basis data terkini mengenai kualitas perairan Natuna pada musim transisi. Penelitian dilakukan di 31 stasiun pada bulan November 2012. Parameter kualitas air yang diukur antara lain kecerahan, derajat keasaman (pH), oksigen terlarut, suhu, salinitas, padatan tersuspensi total atau Total Suspended Solids (TSS) dan nutrien (nitrat, fosfat, silikat). Parameter pH, oksigen terlarut, suhu, dan salinitas diukur secara in-situ menggunaan alat water quality meter (TOA-DKK), kecerahan diukur menggunakan secchi disk, sedangkan sampel air di bawa ke laboratorium untuk dianalisis konsentrasi nutrien dan TSS. Hasil penelitian menunjukkan nilai kisaran kecerahan yaitu 2-20,9 (m), pH 8,09-8,27, oksigen terlarut 6,34-7,96 (mg/l), suhu 29,2-30,6 (°C), salinitas 27,9-30,4 (PSU), TSS 3-26 (mg/l), nitrat 0,005-0,078 (mg/l), fosfat 0,005-0,015 (mg/l) dan silikat 0,045-0,704 (mg/l). Hasil penelitian dibandingkan dengan baku mutu air laut untuk biota laut berdasarkan Keputusan Menteri Lingkungan Hidup Nomor 51 Tahun 2004. Berdasarkan hasil penelitian, kondisi perairan Natuna masih tergolong baik untuk menunjang kehidupan biota laut.Kata kunci: Parameter kimia; Parameter fisika; Natuna; musim transisi

Abstract

Nusa Penida, Bali was designated as a Marine Protected Area (MPA) by the Klungkung Local Government in 2010 with support from the Ministry of Marine Affairs and Fisheries, Republic of Indonesia. Mangrove forests located in Nusa Lembongan Island inside the Nusa Penida MPA jurisdiction have decreased in biomass quality and vegetation cover. It’s over the last decades due to influences from natural phenomena and human activities, which obstruct mangrove growth. Study the mangrove forest changes related to the marine protected areas implementation are important to explain the impact of the regulation and its influence on future conservation management in the region. Mangrove forest in Nusa Penida MPA can be monitored using remote sensing technology, specifically Normalized Difference Vegetation Index (NDVI) from Landsat satellite imagery combined with visual and statistical analysis. The NDVI helps in identifying the health of vegetation cover in the region across three different time frames 2003, 2010, and 2017. The results showed that the NDVI decreased slightly between 2003 and 2010. It’s also increased significantly by 2017, where a mostly positive change occurred landwards and adverse change happened in the middle of the mangrove forest towards the sea.
