PENATAAN SISTEM DRAINASE KAMPUNG BARU DI KELURAHAN TIRTO KOTA PEKALONGAN DALAM RANGKA PENANGULANGAN BANJIR

ABSTRAK

Kampung Baru Kelurahan Tirto Kota Pekalongan merupakan salah satu kampung di Kota Pekalongan yang terdampak ROB Air Laut sehingga di kampung tersebut sering terdapat genangan air ROB dan tinggi nya curah hujan di daerah tersebut. Pada penelitian melakukan beberapa tahapan meliputi dari perhitungan
analisis frekuensi sebaran hujan, uji sebaran distribusi, intensitas hujan, debit banjir metode rasional, kapasitas saluran eksisting, dan review design. Penelitian ini
digunakan untuk mengetahui kapasitas saluran drainase dalam menampung debit limpasan air hujan dengan kala ulang 10 tahun. Hasil simulasi menunjukkan semua saluran drainase yang terdapat di Kampung Baru tidak mampu menampung kapasitas debit banjir sehingga terjadi genangan banjir yang mengakibatkan aktivitas warga terganggu, Sehingga perlu adanya review dimensi saluran pada kapasitas penampang saluran drainase saluran menuju Rumah Pompa.

Kata Kunci : Genangan Air, Analisis Drainase, Review Dimensi Saluran

ABSTRACT

Kampung Baru, Tirto Village, Pekalongan City is one of the villages in Pekalongan City that is affected by seawater ROB, so in this village there are often standing ROB water and high rainfall in the area. The research carried out several stages including calculating rain distribution frequency analysis, distribution distribution tests, rain intensity, rational method flood discharge, existing channel capacity, and design review. This research was used to determine the capacity of
drainage channels to accommodate rainwater runoff with a return period of 10 years. The simulation results show that all the drainage channels in Kampung Baru are unable to accommodate the flood discharge capacity, resulting in flood inundation which disrupts residents' activities, so it is necessary to review the channel dimensions on the cross-sectional capacity of the drainage channels leading to the Pump House.
