Abstract

Penelitian ini bertujuan untuk menganalisis dan mengklasifikasi potensi  radiasi matahari untuk pengembangan pembangkit listrik tenaga surya di Sulawesi Tenggara. Data yang digunakan pada penelitian ini diperoleh dari hasil pengukuran simulasi satelit Meteonorm antara lain radiasi global horizontal, radiasi penyebaran horizontal, kelembapan relatif, temperature udara dan kecepatan angin dengan menggunakan software PVsyst V6.87 serta RapidMiner 9.7 untuk analisis klasifikasi decision tree. Metode hipotetik (mean hipotetik) digunakan untuk penentuan nilai tinggi dan rendahnya radiasi matahari dan evaluasi validasi klasifikasi menggunakan cross validation (confution matrix) serta mengukur nilai validasi klasifikasi menggunakan nilai kesepakatan kappa. hasil penelitian diperoleh rata-rata bulanan pada Januari-Desember dengan lokasi Kendari, Bau-Bau, Muna, Konawe Utara dan Kolaka yaitu Radiasi global horizontal rata-rata 142,5– 156,3 kWh/m², Radiasi penyebaran horizontal 72,4 – 73,4 kWh/m², Temperature udara mencapai 26,8 – 27 °C, Kelembapan relatif mencapai 81,5 – 85,2 %, Kecepatan angin mencapai 1,2 – 1,3 m/s. Hasil analisis klasisfikasi menunjukkan bahwa tiga lokasi paling potensial untuk pengembangan Pembangkit Listrik Tenaga Surya dengan merujuk pada nilai radiasi global horizontal tertinggi yaitu Kolaka 156,3 kWh/m², Kendari 155,1 kWh/m² dan Konawe Utara 154,7 kWh/m² serta dua lokasi potensial terendah yaitu Muna 148,5 kWh/m² dan Bau-Bau 142,5 kWh/m². Dalam uji validasi model klasifikasi decision tree menggunakan cross validation (confusion matrix) di dapatkan nilai accuracy 64 % dan accurasi error 36%, precision rata-rata 68,33 % , recall (Tinggi) 27,27 % dan recall (rendah) 92,86%. Kata kunci : Klasifikasi Radiasi Matahari, Meteonorm, PVsyst, Rapidminer

Abstract

Southeast Sulawesi is one of the largest nickel-producing centers in Indonesia, marked by the booming development of nickel processing industries (smelters) utilizing the Rotary Kiln Electric Furnace technology. This technology serves as the backbone of lateritic nickel refinement. However, access for Mechanical Engineering students to Rotary Kiln Electric Furnace technology for internship and research purposes is very limited, creating a gap between the academic curriculum and industry needs. This community service activity aims to bridge this gap through a scientific seminar that introduces the Rotary Kiln Electric Furnace working principles, key components relevant to Mechanical Engineering, and the available job descriptions in smelters. The implementation method includes interactive material delivery and in-depth discussions. The results of the activity show an increase in students' understanding of the Rotary Kiln Electric Furnace nickel processing cycle and the identification of the crucial role of Mechanical Engineering in the operation and maintenance of the Rotary Kiln, electric furnace, and supporting utility systems. The benefit gained is that students are equipped with foundational knowledge of Southeast Sulawesi's leading nickel technology, enhancing their readiness to compete in the job market within the smelter industry.
