ABSTRAK

Pantai Takisung merupakan salah satu kawasan wisata pantai yang terletak di Kecamatan Takisung Kabupaten Tanah Laut Kalimantan Selatan. Dekat kawasan pantai tersebut terdapat suatu perairan tergenang yang memiliki kekhususan. Pada penelitian ini bertujuan untuk mengetahui status mutu ait dan tingkat kesuburan di perairan kawasan mangrove Pantai Takisung. Penentuan lokasi dilakukan dengan menggunakan metode purposive sampling dimana lokasi penelitian ditentukan berdasarkan lokasi yang dianggap penting dan dapat mewakili serta menggambarkan status mutu air. Pengukuran variabel kualitas air dianalisis di Laboratorium Kualitas Air Fakultas Perikanan dan Kelautan Universitas Lambung Mangkurat. Analisis data dalam kegiatan penelitian ini terdiri dari analisis data kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa dari hasil pengukuran parameter analisis kualitas air pada Kawasan mangrove di Pantai Takisung yang menunjukkan status mutu air di Kawasan mangrove pantai takisung termasuk dalam kategori skor 5,0 < Pij ≤ 10 yang dapat dikatakan tercemar sedang. Selanjutnya pada hasil pengukuran Fosfat dan Nitrat di kawasan Nypa fruticans dan Avicennia alba Pantai Takisung pada saat pasang dan surut dapat dikatakan memiliki tingkat kesuburan kadar Fosfat (PO4) di Kawasan mangrove pantai takisung masuk kategori subur. Sedangkan pada tingkat kesuburan kadar Nitrat (NO3) pada Kawasan pasang dan surut Nypa fruticans dan pasang di kawasan Avicennia alba dikategorikan Oligotrofik. Sedangkan saat surut di Kawasan Avicennia alba dikategorikan Eutrofik.

ABSTRACT

Takisung Beach is a beach tourism area located in Takisung District, Tanah Laut Regency, South Kalimantan. Near the coastal area there is a stagnant waters that have specificity. This study aims to determine the status of water quality and fertility levels in the waters of the mangrove area of Takisung Beach. Location determination was carried out using a purposive sampling method where research locations were determined based on locations that were considered important and could represent and describe the status of water quality. Measurement of water quality variables was analyzed at the Water Quality Laboratory, Faculty of Fisheries and Maritime Affairs, University of Lambung Mangkurat. Data analysis in this research activity consisted of quantitative and qualitative data analysis. The results showed that the results of measuring the parameters of water quality analysis in the mangrove area on Takisung Beach showed that the water quality status in the mangrove area on Takisung beach was included in the score category 5.0 < Pij ≤ 10 which can be said to be moderately polluted. Furthermore, the results of measurements of Phosphate and Nitrate in the Nypa fruticans and Avicennia alba areas of Takisung Beach at high and low tide can be said to have a fertility level of Phosphate (PO4) levels in the mangrove area of Takisung beach which is categorized as fertile.
