Abstract
Sepanjang aliran Kali Konto merupakan daerah lahan irigasi pertanian, banyak
bangunan air irigasi yang dibangun termasuk Bangunan Pengendali Sedimen
(BPS) yang dilengkapi pintu pengambilan air. Namun bencana lahar dingin yang
terjadi pasca letusan Gunung Kelud 2014 membawa material sedimen dan batuan
yang menyebabkan kerusakan infrastruktur BPS Kali Konto dan membahayakan
penduduk sekitar. Oleh karena itu perlu dilakukan pemeliharaan perbaikan BPS
tersebut ke kondisi semula. Permasalahan yang timbul adalah dana yang tersedia
tidak mencukupi untuk melakukan semua usaha perbaikan infrastruktur tersebut.
Untuk itu perlu dilakukan prioritas BPS yang akan diperbaiki.
Penelitian ini menghitung angkutan sedimen total yang terjadi menggunakan
rumus angkutan sedimen kemudian dibandingkan dengan uji sedimen
laboratorium. Kemudian dilakukan analisa kondisi struktur BPS, volume
tampungan sisa, fungsi perlindungan bangunan di hulu dan potensi pendapatan
serta manfaat sosial. Hasil analisa tersebut menjadi inputan reponden dalam
kuesioner proses pengambilan keputusan pemeliharaan BPS dengan AHP. Dari
kajian didapat dari sebelas BPS hanya lima bangunan yang memiliki pintu
pengambilan air irigasi dengan urutan prioritas perbaikan yakni BPS pertama
Siman bobot prioritas (0.353), BPS kedua Lemurung bobot prioritas (0.249), BPS
ketiga Oro-oro ombo bobot prioritas (0.165), BPS Keempat Damarwulan bobot
prioritas (0.151) dan terakhir BPS Badas bobot prioritas (0.082). ========== Along Kali Konto river is an area of irrigation land farming, many water
infrastructures has been build including sabo facility or Bangunan Pengendali
Sedimen (BPS) and irrigation weirs. But the cold lava disaster that occurred in
2014 after Mount Kelud eruption cause damage to BPS infrastructures located in
Kali Konto and endanger people around it. Therefore it is necessary to repairs all
of BPS to its original state. The problem is there no enough funds available to
repairs all BPS infrastructure. That is why priority maintenance should be done to
guide the government agency to choose which BPS should be repaired first.
This study calculates the total sediment transport occurs using sediment
transport formula then compared with the sediment testing laboratory. Then
analyzed the condition of BPS’s structure , sediment storage capacity and revenue
potential as well as social benefits. And last the priority effor using Analytic
Hierarchy Process using questionnaire that completed by respondent. From the
study could btained that eleven BPS only five buildings that has irrigation intake
and the list of which BPS should be repaired first is :The First BPS Siman
condition (36.92%), The second BPS Lemurung (63.33%), the third BPS Oro-oro
Ombo condition (84%), the fourth BPS Damarwulan (90.4%) and the last BPS
Badas (90%).
