Penelitian ini bertujuan untuk menentukan tingkat kerentanandan pola sebaran banjir dengan menggunakan analisis Sistem Informasi Geografis(SIG). Penentuan tingkat kerentanandan pola sebaran banjir di dasarkan atas tingkat curah hujanyang sangat tinggi kurang, yakni lebih dari 2.838 mm per tahun sehingga dapat berpotensi terjadinya banjir. Penelitian ini dilakukan di Daerah Aliran Sungai (DAS) Mede, Kabupaten Halmahera Utara. Untuk mengukur tingkat kerentanan banjir dan pola sebaran banjir digunakan metode Aritmatika dengan penentuan nilai interval. Hasil analisis menunjukkan daerah yang kurang rentan seluas 318,92 ha yang terletak di bagian hulu dan hilir DAS dengan persentase 5,74%. Bagian hulu dan sekitarnya merupakan bagian yang memiliki kelas rentan dengan luas yaitu 3226,10 ha dengan persentase 57,79%. Sedangkan yang tergolong sangat rawan adalah bagian hilir dengan luas wilayah 2037,06 ha 36,49%. Dari hasilyang di peroleh untuk mengendalikan kejadian banjir, harus adanya penataan pola penggunaan lahan di sekitar DAS Mede.Kata Kunci: Limbah Domestik , Kualitas Air, Pencemaran Air, Baku Mutu
Peanut is a plant that has an important role in land and has a high selling value. Therefore it is necessary to take appropriate steps to develop peanut cultivation in the Panasen Sub-watershed by knowing the level of land suitability. The problems faced by the community are 1) lack of interest in the community to plant peanuts, 2) land-use change from agricultural land to lodging land 3) land evaluation has never been carried out for peanut plants in the area. The study used a land unit approach supported by soil analysis, plant growth requirements, and matching. The results showed that the research area was classified as suitable for peanut plants with a suitability class S2 (quite suitable) with a total of 4 land units, namely S2rfns (945.41 ha), S2sn (1675.15 ha), S2srn (938.05 ha), S2sn (13.45 ha) and class suitability of S3 (according to marginal) with 2 land units, namely S3s (12.95 ha), S3s (15.67 ha). The limiting factors for suitability class S2 are root media (r), nutrient retention (f), nutrient availability (n) and terrain (s). The limiting factor for suitability class S3 is the field (s). The limiting factor for N1 land suitability is nutrient availability (n), root media (r) and terrain (s). The limiting factors for conformity class N2 are the field (s) and the rooting medium (r).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
