Abstract: | Sistem drainase bawah permukaan (sub-surface) menjadi alternatif teknologi
yang dapat diterapkan dalam manajemen pengairan. Salah satu teknologi untuk
meningkatkan kinerja drainase bawah permukaan melalui selubung pipa. Penerapan
urugan pasir diperkuat kalsit berpotensi sebagai selubung filter sekaligus penahan
beban sehingga perpaduan modifikasi perforated pipe dan urugan pasir kalsit dapat
menjadi alternatif. Penelitian ini bertujuan menganalisis pengaruh modifikasi
perforated pipe dengan urugan pasir kalsit untuk drainase air. Pipa yang digunakan
adalah sheet-pipe (SP) dan modifikasi perforated pipe (PP) dari bahan PVC dengan
ukuran lubang 2 mm. Pengujian yang dilakukan diantaranya pengujian sifat fisis
tanah, laju aliran, acid leaching, sedimen, dan kekuatan pipa. Hasil menunjukkan
bahwa SP dan PP dapat mengalirkan air dengan lancar dan stabil. Laju aliran
maksimum SP sebesar 189 g/det dan PP sebesar 173,3 g/det. Ditinjau dari distribusi
kalsit dan sedimen, hasil menunjukkan bahwa pada SP dan PP dengan urugan pasir
kalsit sudah terdistribusi dengan cukup baik namun masih ada butir pasir dan kalsit
yang lolos sementara pada geotekstil sangat sedikit yang lolos. Dari segi kekuatan,
pipa PVC lebih kuat dan kaku dibanding sheet pipe. The sub-surface drainage system is an alternative technology that can be applied in water management. One of the technologies to improve subsurface drainage performance is through envelope pipe. The application of calcite reinforced sand backfill has the potential to use as a filter envelope as well as load bearing so that a modified combination of perforated pipe and calcite sand backfill can be an alternative. This study aims to analyze the effect of modification of perforated pipe with calcite sand fill for water drainage. The pipes used are sheetpipe (SP) and a modified perforated pipe (PP) made of PVC with a hole size of 2 mm. The tests carried out included testing the physical properties of the soil, flow rate, acid leaching, sediment, and pipe strength. The results show that SP and PP can drain water smoothly and stably. Maximum flow rate of SP is 189 g/s and PP is 173,3 g/s. In term of distribution of calcite and sediment, the results show that in SP and PP with backfill calcite sand is distributed quite well but there are still grains of sand and calcite that escape while in geotextiles very few escaped. In terms of strength, PVC pipe is stronger and stiffer than sheet pipe. |
