STUDI POTENSI TEKNOLOGI FOG HARVESTING SEBAGAI SOLUSI ALTERNATIF PENYEDIAAN AIR BERSIH DI KECAMATAN KOBALIMA, NUSA TENGGARA TIMUR
Abstract
Abstrak: Kekeringan yang terus melanda wilayah Nusa Tenggara Timur, khususnya Kecamatan Kobalima, menyebabkan krisis air bersih yang memaksa masyarakat menempuh jarak jauh, bahkan harus mengantri air hingga dini hari. Penelitian ini hadir sebagai solusi alternatif berbasis potensi lokal, kabut pegunungan yang melimpah saat dini hari. Dengan teknologi sederhana berupa sistem fog catcher menggunakan jaring, talang, dan penampung air, penelitian ini menjadi pilot project yang berupaya memanen air dari kabut secara efektif. Hasil analisis data iklim selama 11 tahun menunjukkan kondisi yang sangat mendukung terbentuknya kabut radiasi, terutama saat kelembapan tinggi dan suhu turun di malam hari. Estimasi volume air yang dapat ditangkap mencapai 83 liter per malam untuk jaring 3 m². Penelitian ini menekankan pendekatan partisipatif dan pemberdayaan masyarakat sebagai kunci penerimaan teknologi ini sebagai solusi komplementer terhadap kelangkaan air yang kronis dan berulang setiap musim kemarau.
Abstract: Prolonged drought in East Nusa Tenggara, particularly in Kobalima District, has led to a clean water crisis, forcing communities to walk long distances and queue for water late into the night. This study offers an alternative, locally rooted solution—harnessing abundant early morning mountain fog. Using a simple fog catcher system consisting of mesh, gutters, and water storage, this pilot project aims to harvest water from fog efficiently. Climate data analysis over the past 11 years reveals ideal conditions for radiation fog, especially during nights with high humidity and falling temperatures. Estimated water capture can reach up to 83 liters per night using a 3 m² mesh. This research emphasizes a participatory approach and community empowerment as key strategies for the adoption of this simple technology, serving as a complementary solution in regions suffering from chronic and seasonal water scarcity.
