Abstract

The development of Batu as a tourist and agropolitant city has led to some concern, such as water resources. The number of springs has increasingly declined due to the conversion of forest into agriculture land, residential, and tourist sites. Therefore, it’s necessary to maintain equilibrium through the process of extracting and replenishment of rain water by absorbing it into soil pores as water conservation efforts. This study examines the analysis of water conservation based on the concept of zero runoff, located in the Block Office area. It is expected to become input for the Batu City Government and be developed in those area. The analysis of surface runoff is calculated by Rational Method. The dimension of recharged well is calculated by using SNI method 03 2453 2002. The magnitude of design discharge obtained with 5 years return period is 111,408 mm. Reharged well is planned with 5 meters height and 1 meter diameter. Recharged well used for 100 m roof area is 1. Water conservation technology by using recharged well is able to collect runoff from the roof, while retention pool collect and absorb runoff from the parking area, road, and yard.

Abstract

Kawasan padat penduduk Kelurahan Naikoten I, Kecamatan Oebobo, Kota Kupang setiap terjadi hujan dengan intensitas yang cukup tinggi selalu terjadi banjir/genangan air. Hal tersebut terjadi hampir di semua jalan/gang terutama di ruas Jalan Soeharto, Pasar Inpres Naikoten, depan SMU Kriten Nikoten dan Jalan Untung Suropati. Genangan disebabkan hampir semua permukaan tanah tertutup dengan lapisan kedap air, kesadaran masyarakat yang minim serta sebagian jalan/gang tidak memiliki saluran drainase. Studi dilakukan di Wilayah DPS Drainase Dendeng dan Merdeka, Kelurahan Naikoten I. Hasil studi menunjukkan besarnya debit rencana sistem DPS Drainase Dendeng dan Merdeka untuk kala ulang lima tahun masing-masing sebesar 24,017 m3/dt dan 4,775 m3/dt. Terdapat 9 saluran yang tidak mampu menampung debit rencana pada DPS Drainase Dendeng dan 8 saluran pada DPS Drainase Merdeka. Beberapa penyebab terjadinya saluran yang tidak mampu menampung debit rencana yaitu kurang terawat dan terdapatnya sampah pada saluran drainase.Upaya penanganan pada beberapa saluran yang tidak mampu menampung debit rencana yaitu dengan mendesain ulang dimensi saluran dan merencanakan kolam penampung. Selain penanganan tersebut dilakukan pula rekomendasi penanganan secara menyeluruh mengenai kebijakan-kebijakan pemerintah daerah yang melibatkan masyarakat setempat dan mengarah kepada pemberdayaan masyarakat dalam memelihara saluran drainase, pembangunan sumur resapan pada setiap rumah, serta izin dalam pendirian bangunan.Kata Kunci : Sistem Drainase, Genangan, Konservasi Air

Abstract

Sutami Dam is a dam with the largest reservoir with managed by Perum Jasa Tirta I. This reservoir has been operating for more than 39 years (operates in 1972 and using reference to recent data in 2011). This study was performed to determine the trend of sediment discharge and reservoir live time in order to find out how the rest of the remaining Sutami reservoir for reservoir operations. Data analysis is used as the data for 6 years period and in 1972 data for comparison. Point source of sediment in the reservoir is divided into two points, Sutami sediments by direct inflow to the the Sutami Reservoir (Metro River) and outflow from Sengguruh Reservoirs (Brantas River and Lesti River). The third point is the calculation of sediment discharge to determine the most influential point sediment carrier in Sutami Reservoir. Reservoir live time to the rest of Sutami calculated using three methods of approach. Volume approach, elevation approach, and empirical approaches. 2 Tanpa nomer halaman The point that has the most impact is of the Brantas River (inflow from Sengguruh Reservoir) with Qs = 2.27 kg/sec (2011), then from the Metro River with Qs = 1.97 kg/sec (2011). ). Based on the analysis of the remaining life time for Sutami Reservoir using three methods of approach, it is known to Sutami Reservoir live time trends tend to decrease. Elevation control point (+233.3 m) with elevation approach and volume approach gives results for the remaining life of 5 years and 1.5 years, while the empirical approach with 97% trap efficiency give results 9 years for the remaining life time of Sutami Reservoir.Key words: Sutami Reservoir, Sedimentation, Reservoir Live Time

Abstract

The change of global climate influences the temperature, relative humidity, sunlight time, wind rate, rain rate, and river debit. The higher intensity of rain rate after the change of climate influences the fluctuation of river debit in rainy or dry season. Flood and dryness are natural occasions, which are usually occurring. Sutami Reservoir is functioned to retain water excess from rain and river debit from Brantas River, which in the future it would be stored. River debit is used to fulfill water need in dry season. Therefore, to face the extreme effect, there is needed management planning of reservoir operation managed well and optimally. Methodology used in climate change analysis toward operation model of Sutami Reservoir is Stochastic Dynamic Program and it is obtained a policy system of operation model output before and after climate change. Based on the result of analysis, it shows that there is climate change in Sutami Reservoir where it is signed that optimally reservoir output is changed. In the table of optimally reservoir output shows that before climate change the output policy is still in good condition while after it, the output policy is change where there is any displacement of wet season and dry season in which it causes the debit to Sutami Reservoir changed from what had been expected.Key words: climate change, reservoir operation model, stochastic dynamic program
