Abstract
Abstrak: Minimnya ketersediaan air bersih dan keterbatasan sarana untuk mendapatkannya membuat masyarakat Kecamatan Bayan, Kabupaten Lombok Utara (KLU) rentan terhadap krisis air. Secara geografis sebagian besar wilayahnya merupakan pesisir pantai yang kaya akan cahaya matahari, mengingat dalam setahun bulan basah hanya terjadi 3-4 bulan. Air laut dapat menjadi bahan baku air bersih melalui teknologi desalinasi dengan menggunakan sinar matahari sebagai sumber panas. Melalui kegiatan Ipteks bagi masyarakat, alih teknologi pembuatan alat desalinasi berbasis tenaga surya di Kec. Bayan, KLU dilakukan. ÃÂ Kegiatan meliputi sosialisasi pada beberapa kelompok tani Kec. Bayan tentang prinsip kerja alat yang telah diuji coba di laboratorium kimia Universitas Mataram. Praktik kerja pembuatan alat juga dilakukan agar kelompok tani dapat membuat alat sekaligus dapat menyalurkan pengetahuan dan keterampilan kepada anggota masyarakat lainnya. Produk kegiatan diharapkan menjadi salah satu alternatif solusi untuk mengatasi krisis air walaupun masih diperlukan peningkatan produktivitasnya.

Abstrac: The lack of clean water and limited access to get it made public of Bayan District, North Lombok (KLU) were vulnerable to the water crisis. Geographically, most of KLU is coastal region that rich in sunshine, considering the wet months of the year only occur 3-4 months. Sea water can be the raw material of fresh water through desalination technology using sunlight as source of heat. Through IbM activity, transfer technology by producing and setting desalinator based on solar power in the Bayan district, KLU has been done. The activity included socialization on some farmer groups of Bayan district about basic principle of the desalinator that has been tested in the Chemistry Laboratory at Mataram University.ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ Practicing on production of desalinator also has conducted, hence they can produce and share their knowledge and skills to other community. Product activity is expected to be an alternative solution to overcome the water crisis despite still needed some refinement for increasing its productivity.
