Abstract

Sungai Krueng Jantho mempunyai peranan penting dalam pemanfaatan sumber daya air, konservasi DAS, dan pengendalian daya rusak air. Pengerukan material sungai telah berdampak pada rusaknya faktor ekologi sungai Krueng Jantho, khususnya degradasi dasar sungai yang dapat memicu runtuhnya tebing sungai dan pilar jembatan. Tujuan studi ini adalah untuk mengkaji dan merencanakan bangunan pengaturan sungai Krueng Jantho. Lokasi yang ditinjau terletak di Desa Alue Gintung Kecamatan Seulimuem Kabupaten Aceh Besar . Data dan peta yang dikumpulkan adalah peta daerah aliran sungai, data debit sungai dari pos pengukuran muka air (AWLR) Krueng Aceh, dan data topografi serta penampang sungai. Metode perhitungan pembangkitan data debit digunakan metode Markov Chain, analisis debit banjir rencana menggunakan metode distribusi Log Pearson tipe III, dan perencanaan bangunan groundsill untuk pengaturan dan pengamanan dasar sungai. Bangunan groundsill untuk debit 25 tahunan direncanakan dengan lebar groundsill 80,00 m, tinggi groundsill 1,00 m  dan tebal mercu groundsill 4,00 m.

Abstract

Krueng Jantho river has an important role in the utilization of water resources, watershed conservation, and control of water damage. Dredging of river material has resulted in damage to the ecological factors of the Krueng Jantho river, specifically the degradation of the riverbed which can trigger the collapse of river banks and bridge pillars. The location under review is located in Alue Gintung Village, Seulimuem District, Aceh Besar Regency. Data and maps collected are watershed maps, river discharge data from the Krueng Aceh water level measurement post (AWLR), and topographical and river cross-section data. The method of calculating the generation of discharge data is used the Markov Chain method, the analysis of flood discharge plans using the Pearson Log type III distribution method, and the groundsill building planning for river bottom management and security. The groundsill building for the 25 yearly discharge is planned to be 80.00 m wide, groundsill 1,00 m high and 4.00 m thick groundsill lighthouse.
