Kinerja Sistem Jaringan Drainase Kota Semarapura Di Kabupaten Klungkung

Abstract

Urban drainage is one of basic facilities and infrastructure of a town which is cincidered quite important. Agood city needs to consider the condition of the drainage system, because if a settlement is flooded, it will greatly impact the lives of the city. Buildings will be easily damage, environments will be unhealthy and settlements will turn into slumps. The case of flooding is not only in big cities but also emerged in the town of Semarapura that extents only, 5,151 km2. From the conditions on ground, puddles can still be found in some locations, so based on the fact it is necessary to issue reviewing Semarapura drainage system to improve the drainage system in the region. The study in this research has the sense of a systematic search of the drainage problems from an investigation in order to get treatment effort. The approach applied in this research was exploratory and descriptive analytical approach. Data were collected through questionnaires an in-depth interviewers with selected agencies using purposive sampling method. Data analysis was perfomed by descriptive qualitative using likert scale to measure the attidudes, opinions and perceptions of tge performance of the drainage system. The analysis was performed with the aids of SPSS version 20.0, through several stage of the test process to the data sample. The result of the study showed that the influence of the level of maintenance operation, technical management and overall was high at 93,5% with the regression equation Y = -4.874 + 0.405 X1 + 0.228 X2 + 0.089 X3 and the remaining 6.5% was influenced by other factors. From the equation it can be seen that the maintenance operations were more dominantly affected on the performance of the drainage system in Semarapura town District of klungkung compared with management and technical. The effort carried out to increase performance system of Semarapura town drainage network is to construct a structured system of maintenance operations so that it can be performed on a regular basic, establish drainage management institutions that it’s authority and responsibility can be coordinated as directed an make clear rules of management system, make repairs damage drainage infrastructure in accordance with the technical requirement.

Tingkat Kepedulian pada Implementasi Sistem Drainase Sesuai dengan Zero Delta Q dan Faktor Keberhasilannya pada Pengembangan Apartemen Di Surabaya

“…Sistem drainase bisa berubah sesuai dengan kebutuhannya, dilihat dari kapasitas alir dan tampungnya, sistem drainase harus dapat beradaptasi dengan perubahan limpasan ataupun tampungan, berbeda dengan bangunan drainase dan pelengkapnya, evaluasi pada sistem drainase ini lebih fleksibel untuk dirubah terutama jika bangunan sistem drainase tersebut dilengkapi dengan pintu air [6]. Drainase memiliki banyak fungsi, diantaranya: (1) Mengeringkan daerah becek dan genangan air.…”

“…Pemeliharaan bangunan drainase harus dilakukan secara berkala dan pengecekannya harus memperhatikan aspek-aspek teknis pada bangunan drainase tersebut karena hal itu berkaitan dengan kinerja (daya alir dan daya tampung) sebuah bangunan drainase. Frekuensi pengecekan dan pemeliharaan suatu bangunan draianse disesuaikan dengan kebutuhan dan kondisi pemakaian bangunan drainase tersebut [6]. Gambar 4 adalah ilustrasi penamaan dari indikator-indikator pada faktor tiga.…”

Artificial viscosity technique for direct runoff calculation

“…Therefore, this can be misinterpreted for some conditions. In some studies, the GAMA-1 method produced significant discrepancies for the observed discharge of up to 80% [12][13]. This was expressed by Limantara [14] that ideally, each basin should have its own unit hydrograph, and thus, it can be used for the other basins with similar characteristics.…”

“…This becomes the foundation in developing the Limantara method that was tested for some locations in Indonesia such as Java, Bali, Lombok, and Kalimantan. However, Andiese [12] and Kristianto et al [13] showed that the Limantara method still produced significant discrepancies to estimate the observed discharge.…”
