Abstract

Irrigation channel in D.I. Timbang Deli, Deli Serdang district Sumut province has a total area of 520 Ha and a 5000 meter long secondary channel. Irrigation channel in D.I. Timbang Deli overgrown vegetation at the base and wall of the channel so it is expected to affect roughness. The objective of the study was the flow resistance with the variation of vegetation volume to the variation of the discharge. The method used in this study is field observation by measuring flow velocity, flow depth and vegetation volume (VT) on trapezoidal tract width of 3.75 m and height of 0.90 m along 154 m. Measurements were performed on 3 points of upstream, middle and downstream channels and 5 transverse dots X1 through X5 4 times with D1 debit variation of 1.32 m³/s and D2 of 0.98 m³/s. The dominant vegetation channels are rigid. Measurement velocity using current meter while for vegetation volume (VT) using grid method. The results showed that vegetation volume VT0 (0,00 m³/0,00%), VT1 (52,417 m³/21,14%), VT2 (70,7921 m³/24,51%) and VT3 (83,053 m³/30,42%). It is seen that the increase in vegetation volume can affect the flow resistance. The result of measurement increased the resistance of flow to VT0 0,052, VT1 equal to 0,062 with percentage 16,13%, VT2 equal to 0,108 with percentage 51,85% and VT3 equal to 0,122 with percentage 57,37% atD1. Meanwhile, at D2 there is an increase of flow resistance to VT0 by 0,044, VT1 is 0,052 with percentage 15,38%, VT2 equal to 0,058 with percentage 24,14% and VT3 equal to 0,070 with percentage 37,14%. This shows that the flow resistance VT0 is smaller than the flow resistance VT1, VT2 and VT3. From the above results are expected to conduct O and P channels by surrounding communities and related government.

Abstract

D. I Timbang Deli is 520 Ha of flow area and 5000 meters of secondary channel is located in Deli Serdang Regency, North Sumatra Province. The turn of the irrigation network in overgrown vegetation on the cliffs and bottom of the channel, is expected to reduce the flow rate. The purpose of the study was to see the distribution of velocity, resistance and energy loss in the secondary channel due to vegetation. The method used is conducting surveys in the field by measuring water depth, vegetation volume and flow velocity. Trapezoidal channel with 36 m length, 1.45 lower width, 3.15 m upper width and 33,510 turn angle. The velocity measured in the middle and downstream regions across the channel is divided from points X1 to X5 with Q1 = 0.62m3/ sec and Q2 = 0.83 m3/sec. The results obtained in the speed distribution in Q1 Vmax mean X1 = 0.296 m/s and X5 = 0.199 m/s, the speed decreases due to the turn of 48.82%. On VV3 Vmaks the average is X4 = 0.216 m/sec and (X1 and X2) = 0,000 m/sec, the volocity decreases due to the presence of vegetation between X1, X2 and X5 at Q1 = 100%. In Q2 the average VV0 Vmax condition of the flow X1 = 0.477 m/s and X5 = 0.323 m/s between X1 and X5 the volocity decreases due to turn 28.45%. VV3 Vmax conditions on average X5 = 0.312 m / s and X1 = 0.000 m / s, between X1 and X5 the speed decreases due to the presence of 100% vegetation. In connection with the above results, with this research the local community and local government can carry out cleaning on the channel on a scale basis.

Abstract

Nagan Raya District Government undertook the construction of roads, including the Poros Utama Road of Kuala Subdistrict. At the time of rain, in certain locations are still formed puddles above the surface of the asphalt. Therefore, it is necessary to evaluate the efficiency and duration of draining flow through the inlet on the road. The data required are the type, distance and dimensions of the existing inlet and the location map, the maximum daily annual rainfall data, cross and longitudinal sectional drawing. Calculations start by calculating the design flow of rainfall data processing. Furthermore, the calculation of the gutter flow as well as the efficiency and the inlet draining time. Based on calculations, the efficiency of the existing inlet in the form of a curb opening inlet is in the range between 4,93% to 6,51% with  0,64-3,92 minutes of draining time. This value indicates that the inlet on the road produces very low efficiency. Inlet is expected to drain all the water or 100% efficiency. The inundation disturbs the movement of the vehicle and affects the pavement resistance. Therefore, the flow of water above the road surface is expected not to create a puddle.

Abstract

Kolam olak merupakan bangunan utama pelimpah yang berfungsi meredam energi pada bendungan. Bangunan ini memanfaatkan pembentukan loncatan hidrolik dalam prinsip peredamannya. Loncatan ini terjadi akibat adanya perubahan aliran dari superkritis menjadi subkritis. Fenomena tersebut dapat menimbulkan turbulensi yang berpotensi menggerus bagian dasar dan hilir bangunan bila tanpa adanya kolam olak. Penelitian ini bertujuan untuk menganalisis karakteristik loncatan hidrolik yang terjadi di kolam olak bangunan pelimpah Bendungan Krueng Kluet Aceh Selatan secara model fisik. Bangunan tersebut menggunakan model tak distorsi dengan skala 1:60 di Laboratorium Sungai dan Pantai Fakultas Teknik Universitas Syiah Kuala, Banda Aceh. Observasi dan pengukuran dilakukan terhadap panjang loncatan hidrolik (Lj), kedalaman aliran (y1 dan y2), dan kecepatan aliran (v) pada variasi debit (Q) dengan periode ulang 2, 5, 10, 25, 50, 100 dan 1000 tahun. Pengujian dilakukan terhadap 2 seri bangunan, yaitu seri awal (S0) dan akhir (S1). Kolam olak S0 menggunakan tipe United States Bureau of Reclamation (USBR) III. Sedangkan S1 dibuat dengan menambahkan adversed slope dengan kemiringan 1:2 di hilirnya dan menurunkan elevasi dasarnya sedalam 4 m. Hasil observasi memperlihatkan bahwa model S1 menghasilkan rerata rasio Lj/y1 (panjang loncatan) < 20-40 % lebih pendek dibandingkan model S0. Selain itu pola disipasi energi yang terjadi pada S1 cenderung lebih meningkat seiring meningkatnya Q dengan kehilangan energi (∆E/y1) maksimum yang diperoleh adalah sebesar 42,6 (lebih besar dari yang dihasilkan oleh S0­­). Sehingga dapat disimpulkan bahwa dasar dan hilir kolam olak model S1 lebih aman dibandingkan dengan model S0.Kata Kunci: Bendungan Krueng Kluet, Kolam Olak, Loncatan Hidrolik, Disipasi Energi, Model Fisik

Abstract

Abstrak PPI di desa Meunasah Keudee kecamatan Mesjid Raya kabupaten Aceh Besar sejak pembangunannya tahun 2013 sampai saat ini belum tersedia fasilitas air bersih yang dibutuhkan nelayan saat pendaratan. Kebutuhan air untuk membersihkan diri (sanitasi), mencuci bagian dalam kapal, dan mencuci hasil tangkapan sulit diperoleh dan sangat minim. Akibat dari keterbatasan tersebut para nelayan harus membeli air bersih melalui depot penjualan yang datang khusus saat kapal mendarat. Hal ini tentu saja cukup memberatkan nelayan dan mengurangi hasil pendapatan mereka. Tujuan dari kegiatan ini adalah penyediaan air bersih dengan menerapkan teknologi tepat guna berupa pemanenan air hujan (PAH) dari atap salah satu bangunan PPI yang ada dan ditampung ke tandon air berkapasitas 1000l. Dari hasil diskusi dan musyawarah informal dengan Perangkat Desa disepakati, tidak hanya menggunakan talang air sebagai pemanen air hujan tetapi juga dilengkapi sumur dangkal. Sehingga kekurangan air bila musim kemarau dapat diatasi. Kata kunci: pemanenan air hujan (PAH), tandon air, sumur dangkal, teknologi tepat guna.  Abstract PPI located at Meunasah Keudee Village, Mesjid Raya District, Aceh Besar Regency, since its construction in 2013 has not yet provided clean water facilities needed by fishermen when their ships landing. The need of water for sanitation is difficult to obtain and quite scarce. As a result, they have to buy water that comes specifically when the ship lands. This of course is quite burdensome for fishermen and reduces their income. The purpose of this activity is the provision of clean water by applying appropriate technology in the form of rainwater harvesting (PAH) from the roof of one of the existing PPI buildings and accommodated into a water tank with a capacity of 1000l. After informal discussion with the Village Head and Panglima Laot, it was agreed that both gutters and shallow well are used to fillup the tank. Hence the lack of water during the dry season can be overcome. Keywords: rainwater harvesting (PAH), water tanndon, shallow wells, appropriate technology

Abstract

Earthquake on July 2, 2013, destroyed several buildings in Aceh Tengah district and Bener Meriah district of Aceh Province. This earthquake gives Aceh government a clue that the seismic hazard map must become the reference in development plan in future. To respond this idea, we conduct the research and try to estimate the amplification factor for developing seismic hazard maps of those districts. This study aims to determine the average shear wave velocity up to the depth of 30 meters (Vs30) and the amplification factor of Aceh Tengah district and Bener Meriah district, to build the seismic hazard map of both districts. In this study, we use the MASW (Multi-Channel Analysis of Surface Waves) with 24 geophones in the frequency of 10 Hz at 10 locations to determine the Vs30 beneath the surface. The soil and rock classification from ASCE 2010 and SNI 1726:2012 used to classify the soil/rock based on Vs30 and calculate the predicted amplification factor using the Borcherdt Eeri equation. The result of this study reveals that the range of Vs30 in the study area is 76 m/s – 308 m/s. The loosest sediment has 76 m/s located at point 2 in Aceh Tengah district. The shear wave velocity of 76 m/s classifies as soft soil (SE). Based on the calculation, the pyroclastic deposit and sediment in the basin of the study area will be amplified the seismic wave in the range of 2.9 to 3.3 times. In the future, we suggest conducting another geophysical survey to determine the correct amplification factor to improve the quality of seismic hazard map.
