Description Penelitian ini bertujuan untuk mengkaji kandungan nitrat dan fosfat di Pantai Jungwok, Kabupaten Gunungkidul, Yogyakarta. Materi penelitian ini adalah air laut Pantai Jungwok. Metode yang digunakan dalam penelitian ini adalah survei dengan pendekatan kuantitatif. Teknik pengambilan sampel air laut menggunakan purposive sampling. Lokasi pengambilan sampel air laut berada di bagian timur, tengah dan barat Pantai Jungwok menggunakan transek garis. Pada masing-masing lokasi terdapat 3 titik sampling dengan jarak 0 meter, 5 meter dan 10 meter dari garis pantai. Pengambilan sampel air untuk pengukuran kandungan nitrat dan fosfat menggunakan botol polyetilen sebanyak 1 liter tiap titik. Analisis kandungan nitrat dan fosfat dilakukan di Laboratorium Balai Besar Teknik Kesehatan Lingkungan dan Pengendalian Penyakit (BBTKLPP) Yogyakarta. Pengukuran suhu, DO, pH dan salinitas dilakukan secara in situ menggunakan alat water quality monitor meter AZ8603. Hasil penelitian menunjukan bahwa kandungan nitrat di Pantai Jungwok berkisar 2,85–8,82 mg/l, sedangkan fosfat berkisar 0,00–0,50 mg/l. Berdasarkan hasil tersebut, maka perairan Pantai Jungwok tergolong dalam perairan mesotrofik hingga eutrofik. Secara keseluruhan hasil nitrat dan fosfat tersebut telah melampaui baku mutu air laut untuk biota laut pada Keputusan Menteri Negara Lingkungan Hidup Nomor 51 Tahun 2004 sebesar 0,008 mg/l dan 0,015 mg/l. Hasil pengukuran secara in situ menunjukkan bahwa suhu, pH, DO dan salinitas di Pantai Jungwok masing-masing berkisar 30,67±0,93-32,20±0,62oC; 9,14±0,29-9,29±0,13; 8,00±1,41-8,93±1,19 mg/l dan 34,83±0,46-35,10±0,10 ppt.
Evaluation of nitrate and phosphate content in seawater of Jungwok Beach, Gunungkidul District, Yogyakarta, was the aim of this study. The method used was a survey with a quantitative approach. Sampling in the eastern, central and western regions of Jungwok Beach was carried out using a purposive sampling technique using line transects. At each site, there were three sampling points with distances of 0 meters, 5 meters and 10 meters from the coastline. One liter of water sample (at each point) was stored in polyethylene bottles. Nitrate and phosphate content analysis was conducted at the Laboratory of the Center for Environmental Health and Disease Control Engineering (BBTKLPP : Laboratorium Balai Besar Teknik Kesehatan Lingkungan dan Pengendalian Penyakit) Yogyakarta. Measurement of temperature, DO, pH and salinity were done in situ using the AZ8603 water quality monitor meter. The results showed that the nitrate concentration in Jungwok Beach ranged from 2.85 to 8.82 mg / l, while the phosphate ranged from 0.00 to 0.50 mg / l. Based on these results, the waters of Jungwok Beach are classified as mesotrophic to eutrophic waters. Overall the results of nitrate and phosphate have exceeded sea water quality standards for marine biota in the Decree of the Minister of Environment No. 51 of 2004 amounting to 0.008 mg / l and 0.015 mg / l. In situ measurement results showed that temperature, pH, DO and salinity at Jungwok Beach were respectively around 30.67 ± 0.93-32.20 + 0.62oC; 9.14 ± 0.29-9.29 ± 0.13; 8.00 ± 1.41-8.93 ± 1.19 mg / l and 34.83 ± 0.46-35.10 ± 0.10 ppt.
