Abstract

Indonesia merupakan negara kepulauan dengan wilayah perairan dangkal yang luas dan aktivitas pelayaran yang tinggi, sehingga berpotensi mengalami pencemaran akibat limbah kapal. Penelitian ini bertujuan merancang dan merealisasikan buoy apung yang stabil, mengintegrasikan sistem pemantauan kualitas air, menerapkan metode Indeks Pencemaran, serta mengevaluasi sistem monitoring dan peringatan dini. Metode penelitian meliputi perancangan tiga model buoy, analisis hidrostatis, stabilitas, periode gerakan, dan Response Amplitude Operator (RAO). Model terpilih kemudian direalisasikan menjadi prototipe berbahan fiberglass dan diuji melalui pengukuran dimensi, kondisi terapung, stabilitas dinamis, serta integrasi sensor pH, suhu, kekeruhan, TDS, GPS, ESP32, komunikasi WiFi, penyimpanan CSV, dan aplikasi berbasis Flask. Hasil menunjukkan Model 1 memiliki performa terbaik. Prototipe memiliki error maksimum 1,94% pada tinggi, 0% pada diameter, dan 0,086% pada sarat. Prototipe mampu mengapung seimbang, kembali ke posisi awal setelah gangguan, dan mendukung integrasi perangkat monitoring. Sistem juga mampu membaca, mengirim,menampilkan, menyimpan data, menentukan status mutu air, serta mengaktifkan alert berdasarkan nilai Indeks Pencemaran. Secara keseluruhan, buoy layak digunakan sebagai platform monitoring dan peringatan dini di perairan dangkal.

Indonesia is an archipelagic country with extensive shallow-water areas and high shipping activity, making its marine environment vulnerable to pollution from ship-generated waste. This study aims to design and construct a stable floating buoy, integrate a water-quality monitoring system, apply the Pollution Index method, and evaluate the monitoring and early warning system. The methods included designing three buoy models and analysing hydrostatic characteristics, stability, motion periods, and Response Amplitude Operator (RAO). The selected model was manufactured as a fiberglass prototype and tested through dimensional measurement, floating-condition assessment, dynamic stability testing, and integration of pH, temperature, turbidity, TDS, GPS, ESP32, WiFi communication, CSV storage, and a Flask based monitoring application. The results showed that Model 1 provided the best performance. The prototype had maximum dimensional errors of 1.94% in height, 0% in diameter, and 0.086% in draft. It was able to float in a balanced condition, recover after disturbance, and support the integrated monitoring devices. The system successfully read, transmitted, displayed, and stored sensor data, determined water-quality status, and activated alerts based on the Pollution Index. Overall, the buoy is suitable as a monitoring and early warning platform for shallow waters.
