Abstract

Sampang is one of East Java’s district, which often flooded annually and worsened lately. One of the causes Sampang flood is uncontrolled landuse basin in the watershed (DAS) of Kemoning Rivers. The objective of the research is to calculate the influence of landuse basin coverage to runoff Kemoning River and flood discharge. This research use formula Q = 0,002778 x Large x Coeffisien x Rainfall. 25th return period of rainfall from Logpearson III distribution is used because the distribution is eligible. The results, Q = 32.86, indicate that a higher coefficient can cause an amount of flood discharge. Sampang local government should increase the areas with a small coefficient (The forest area) to reduce amount of flood discharge. ============================================================================ Sampang adalah salah satu kabupaten di Jawa Timur, yang setiap tahun sering mengalami banjir dan memburuk akhir-akhir ini. Salah satu penyebab banjir sampang adalah tidak terkontrolnya penggunaan lahan di Daerah Aliran Sungai (DAS) Kemoning. Tujuan dari penelitian ini adalah untuk menghitung pengaruh penggunaan lahan DAS terhadap limpasan sungai Kemoning. Penelitian ini menggunakan rumus Q = 0,002778 x Luas x Koefisien x Curah hujan. Penggunaan curah hujan periode 25 tahunan distribusi Log Pearsson III karena telah memenuhi syarat. Hasilnya yaitu Q = 32.86, menggambarkan bahwa semakin tinggi koefisien dapat menyebabkan tingginya debit banjir. Pemerintah Kabupaten Sampang harus menambah area dengan koefisien yang kecil (area hutan) untuk mengurangi debit banjir.
