Description Irrigation water should be managed by integrating a whole system ( Primary, Secundary and Tertiary canal) shoud be according to plan. Government regulations (PP No. 20, 2006) describe that primary and secondary canal should be managed by government and tertiary canal should be managed by farmer. During tertiary canal management, farmer should be equipped with simple and reliable technology, such as knockdown proportional tertiary box. Tertiary box is one of the most important structures in tertiary canal that divide discharge and deliver it to quarternary and then to the field. This paper described the application of modified tertiary box technology that developed using proportional and knockdown .Proportional design has openings that their width is proportional according to the service area. Thus, this tertiary box can ensure equitable water distribution among fields. Knockdown design make this technology can be easily and quickly installed. This technology applied in Ciranjang tertiary system, Cihea Irrigation Area, Cianjur District. Data collected after construction showed that this tertiary box can deliver equitable discharge (lest then 2% error from planned discharge/ average test Lab and KP.05.), have sufficient mechanical strength (385 kg/cm2), inexpensive construction cost (Rp. 1.446.000,-) and highly acceptable by the farmer.On the way to instal the tertiary box should be carefully in order that appropriate with detail design.
Dalam melaksanakan manajemen air irigasi harus terpadu dan saling mendukung (dari Primer, Sekunder dan Tersier) agar air sampai ke lahan sesuai dengan rencana. Sesuai PP. No. 20 tahun 2006 tentang irigasi, bahwa jaringan primer dan sekunder dikelola oleh Pemerintah dan jaringan tersier oleh petani,untuk itu petani harus mengerti dan memahami, serta dapat mengoperasikan bangunan- bangunan yang ada di jaringan tersier tersebut. Untuk mengatasi maka dibuatlah bok tersier dan pembuatannya knocdown dengan lubang keluaran dibuat proporsional sesuai dengan luas layanan. Bila debit yang mengalir kecil atau besar maka dibagi secara propirsional. Dari hasil penerapan dan pengkajian yang dilakukan di Saluran tersier Ciranjang 11, DI. Cihea, Kampung Sukamaju bahwa air yang keluar dari lubang keluaran tidak berbeda jauh kurang 2% dari rencana semula (hasilrata-rata pengujian Lab. dan KP-05), kekuatan beton 385kg/cm² dengan biaya pembuatan dan pemasangan sebesar 1.446.000,-serta keterimaannya petani pada bangunan bok tersebut baik. Biarpun dalam pemasangannya perlu ketelitian supaya bisa tepat bentuknya seperti yang direncanakan.
