Abstract

Limited public understanding and perception of climate change indicate that adaptive capacity at the local level remains constrained. This study aims to examine the perceptions, awareness, and engagement of Central Sulawesi communities regarding climate change. A mixed-mode survey—offline and online—was conducted using a questionnaire with 14 structured items and an open-ended essay prompt for additional suggestions. From the sampled respondents drawn from the entire population of Central Sulawesi, the Margin of Error (MoE) was calculated at 7.92%, with a confidence level of 92.08%. The findings reveal that 96% of participants are aware of climate change, although only a small proportion consider themselves well-informed. Furthermore, 75% regard climate change education as highly important, and 96% identify social media as an effective means for disseminating climate knowledge. Moreover, 43% of respondents believe climate change significantly affects their lives, and 45% express concern about its impacts. A majority support mitigation efforts, endorsing reforestation and educational programs as priority strategies. While public awareness appears relatively high, a gap persists between knowledge and tangible action. These insights highlight community readiness—and existing limitations—for supporting local-level climate change interventions.

Abstract

Artikel ini mengevaluasi akurasi dan penerapan tujuh radiasi matahari global estimasi yang menggunakan suhu lingkungan harian, curah hujan total dan kelembaban relatif di kawasan tropis benua maritim Indonesia. Dua model yang dievaluasi ini adalah model baru model yang diusulkan (PM) untuk memperkirakan tenaga surya radiasi pada permukaan horizontal. Pertama model PM1 menggunakan suhu-presipitasi sebagai input (berbasis TP) sedangkan PM2 kedua Model yang digunakan adalah suhu-presipitasi-relatif kombinasi kelembaban sebagai input (berbasis TPRH). Semua model dievaluasi berdasarkan kesalahan statistik mis. Fraksi Prediksi dalam satu atau dua faktor (FAC2), Mean Bias (MB), Mean Kesalahan Kotor (MGE), Bias Rata-rata yang Dinormalisasi (NMB), Rata-rata Kesalahan Kotor yang Dinormalisasi (NMGE), Kesalahan Root Mean Square (RMSE), Koefisien determinasi (r) dan Koefisien Efisiensi (COE). Hasil penelitian menunjukkan bahwa berbasis TPRH model memiliki akurasi yang lebih baik dibandingkan berbasis T atau berbasis TP. Model PM2 menunjukkan performa terbaik di antara semua model saat Quej et.al model 2016 memiliki akurasi yang baik namun kurang presisi. Ciri-ciri iklim tropis dimana kelembaban tinggi sangat mempengaruhi radiasi matahari yang masuk ke permukaan sementara atau spasial.
