Analisis Intensitas Radiasi Matahari di Manado dan Maros

Abstract

Telah dilakukan analisis intensitas radiasi matahari di Manado dan Maros dengan menganalisis pola grafik intensitas radiasi matahari terhadap sudut deklinasi matahari. Faktor pengaruh atmosfer dianalisis dari pola intensitas radiasi matahari terhadap curah hujan dengan metode regresi linear sederhana pada kedua daerah penelitian. Hasil yang diperoleh berupa nilai intensitas radiasi matahari di Maros lebih tinggi dibandingkan Manado sepanjang tahun, dengan Maros 133.121 gram.cal/cm², dan Manado 117.289 gram.cal/cm². Penerimaan intensitas radiasi matahari di Manado dan Maros dipengaruhi oleh intensitas curah hujan di kedua daerah, yaitu kenaikan curah hujan menurunkan intensitas radiasi matahari, disamping dipengaruhi oleh kondisi geografi lokal dan faktor tutupan awan.

An analysis of solar radiation intensity in Manado and Maros had been performed by analyzing the chart pattern of the solar radiation intensity against angle of solar declination. The effect of atmosphere was analyzed using a simple linear regression method from the solar radiation intensity pattern against the precipitation at the two areas. The results showed that the solar radiation intensity value ​​in Maros was higher than that in Manado throughout the year, which were 133.121 gram.cal/cm² in Maros and 117.289 gram.cal/cm² in Manado. The solar radiation intensity in Manado and Maros was influenced by precipitation intensity in both regions, that was the increasing precipitation intensity decreased the solar radiation intensity, and by local geography and cloud factor.
