Abstract

Penelitian ini bertujuan untuk menganalisis kualitas air laut berdasarkan baku mutu air laut untuk Wisata Bahari sesuai Peraturan Pemerintah RI Nomor 22 Tahun 2021 dan menentukan status mutu berdasarkan Indeks Kualitas Air Laut (IKAL) sesuai Peraturan Menteri LHK RI Nomor 27 Tahun 2021. Pengambilan sampel dilakukan pada September hingga Desember 2024 di tujuh stasiun penelitian kawasan wisata Teluk Yos Sudarso menggunakan teknik purposive sampling. Parameter yang dianalisis meliputi Total Padatan Tersuspensi (TSS), Oksigen Terlarut (DO), Minyak dan Lemak (ML), Amoniak Total (AT), dan Orto-Fosfat (OF). Hasil penelitian menunjukkan nilai TSS berkisar 16-115 mg/L dengan 71,43% stasiun melebihi baku mutu (20 mg/L); DO berkisar 5,3-6,7 mg/L dengan 100% stasiun memenuhi baku mutu (≥5 mg/L); ML berkisar 0,7-6,6 mg/L dengan 85,71% stasiun melebihi baku mutu (1 mg/L); AT berkisar 0,14-0,66 mg/L dengan 100% stasiun melebihi baku mutu (0,02 mg/L); dan OF berkisar 0,01-0,08 mg/L dengan 57,14% stasiun melebihi baku mutu (0,015 mg/L). Berdasarkan perhitungan IKAL, dua stasiun (28,57%) termasuk kategori "Baik" (Pantai Base-G dan Pantai Dok 2), tiga stasiun (42,86%) kategori "Sedang" (Pantai Yakoba, Pantai Ciberi, dan Pantai Pasir II Holtekamp), dan dua stasiun (28,57%) kategori "Kurang" (Pantai Hamadi dan Pantai Holtekamp). Secara keseluruhan, kualitas air laut di perairan Teluk Yos Sudarso belum optimal untuk mendukung aktivitas wisata bahari. Parameter TSS, ML, dan AT menjadi kontributor signifikan terhadap rendahnya nilai IKAL, mengindikasikan tekanan antropogenik yang tinggi. Disarankan pengelolaan kawasan melalui pendekatan zonasi berdasarkan status mutu air, pengendalian sumber pencemaran, pemantauan kualitas air secara berkala, peningkatan edukasi dan partisipasi masyarakat, serta pengembangan infrastruktur pendukung wisata ramah lingkungan.

Abstract

Lake Sentani is the largest lake in Papua and an important raw water source facing pressure from residential expansion, agricultural runoff, domestic wastewater, and small-scale mining. This study developed and internally evaluated the Rational Water Quality Index (RWQI), integrating the Regulatory Violation Index (RVI), Toxicological Severity Score (TSS), and Limnochemical Similarity Coefficient (LSC). Data were collected from 45 sampling points across four limnological zones over three seasonal periods. The first-season dataset (n = 45) was used to develop the PCA-based LSC structure, while the subsequent two seasons (n = 90) assessed its temporal stability without recalibration. Overall performance was evaluated using classification accuracy, ROC/AUC, structural coherence, and consistency with trophic conditions. RWQI achieved 91.56% classification accuracy, AUC = 0.980, and R² = 0.989, outperforming SWQI, OWQI, and the Pollution Index. Spatial analysis identified the Harapan and Flafow River littoral zones as priority areas (RWQI 38.2–43.7, Poor), while the pelagic center maintained Good quality (RWQI 84.2). RWQI shows potential as an adaptive framework for tropical lake assessment, but independent external validation remains necessary before broader standardization.
