Selasih Sumatera Barat <p>A typical relatively steep slope makes the Lb. Selasih – Bts. Kota Padang KM.29+650 experienced a landslide in 2017. So, it is necessary to strengthen the slope to overcome the landslide. Alternative slope reinforcement used is reinforcement using cantilever retaining walls or geotextiles. Slope stability analysis before and after were analyzed using the Slope/W program. The output produced by Slope/W program is the value of the safety factor. The safety factor value for the state of the original slope is 1.100. It shows that the slope in the original condition is unstable and vulnerable to landslide hazards. The retaining wall has a height of 11 m and a base plate width of 8 m. The results of the analysis showed that the cantilever retaining wall securely with stands shear, rolling, and bearing capacity of the subgrade with a safety factor value of 1.620; 1.550; 2.160, while geotextile reinforcement has a height of 16 m and an ultimate tensile strength of 200 kN / m. The results of the analysis showed that the reinforcement of the geotextile safely sliding, stability, and bearing capacity of the subgrade with a safety factor value of 1.600; 2.330; 2.860. Both of these reinforcements are safe to stabilize the slope by increasing the value of the slope safety factor by 2.235 for strengthening the cantilevered retaining wall and 2.279 for strengthening the geotextile.</p> Syahril Alzahri Adiguna Bimo Brata Adhitya Yulindasari Sutejo Reffanda Kurniawan Rustam Copyright (c) 2020 Syahril Alzahri, Adiguna, Bimo Brata Adhitya, Yulindasari Sutejo, Reffanda Kurniawan Rustam 2020-04-27 2020-04-27 9 1 15 24 10.35139/cantilever.v9i1.18 Peningkatan Kapasitas Tempat Penampungan Sementara (TPS) Ciroyom Menjadi Stasiun Peralihan Antara (SPA) Berskala Kawasan di Kecamatan Andir, Kota Bandung <p>Ciroyom TPS is one of the waste facilities in Andir Sub-district. Ciroyom TPS is managed by PD Kebersihan Kota Bandung which works as temporary solid waste collection from residential and Ciroyom Market. The large area of the TPS Ciroyom service area, which is 5 out of 6 villages that produce large amounts of waste that reaches 45.43 tonnes/day. It makes the amount of waste transportation from TPS to TPA reach 12 ritation/day. The distance from TPS (Tempat Penampungan Sementara) Ciroyom to Sarimukti Regional Landfill which requires 44 km is a major consideration needed by the Waste Transfer Station (SPA, Stasiun Peralihan Antara) for regional scale. SPA takes in reducing the volume of waste so that it can reduce the ratio of garbage transportation to landfill (TPA, Tempat Pemrosesan Akhir). With adequate land area, TPS Ciroyom has the potential to improve its function to become SPA for regional scale. Through the analysis of several alternative concepts and development scenarios, the amount of waste generated will be managed at the SPA Ciroyom for the next 10 years. The main facilities designed at the SPA Ciroyom for regional scale are waste compaction units resulting in volume reduction with the vertical compression method. Through solidification of waste, residual waste classified as residues is expected to reduce the volume by 60-70%. In addition, other facilities are provided which are designed at Ciroyom Area Scale SPA such as waste sorting facilities using conveyor belts, organic waste processing with open windrow systems, and inorganic waste recovery facilities that still have selling points.</p> I Made Wahyu Widyarsana Oloan Ivan Daniel Copyright (c) 2020 I Made Wahyu Widyarsana, Oloan Ivan Daniel 2020-05-10 2020-05-10 9 1 25 32 10.35139/cantilever.v9i1.29 Delineasi DAS dan Elemen Model Hidrologi Menggunakan HEC-HMS Versi 4.4 <p>The watershed delineation process is needed and has an essential role in various water resource projects. This study aims to examine the GIS processing function embedded in the latest HEC-HMS software version 4.4 for the delineation of watershed and elements of the hydrological model. In comparison, watershed delineation was also carried out by using ArcGIS software. The area of study is the Bendung subbasin located in Palembang City, where terrain data used is a National DEM data with a spatial resolution of 8 m (0.27 arc-second). The results showed that the boundaries and area of the watershed produced by HEC-HMS 4.4 and ArcGIS showed the same characteristics. The river network produced by the two software shows a slight difference even though the flow patterns are similar. It shows that the level of accuracy and quality of the delineation produced by the HEC-HMS 4.4 is excellent. Besides, elements of the hydrological model can be generated automatically which is not found in previous versions. It allows users to more quickly simulate detailed hydrological models with a large number of elements. Therefore, the use of GIS functions in HEC-HMS 4.4 must be encouraged for various analysis purposes in water resources projects.</p> M.

For successful implementation, it is necessary to identify potential areas for RWH implementation. This study aims to identify areas in Palembang that are potential for implementing the RWH system. An analysis of parameters that affect the classification also conducted. This study used a geographic information system (GIS) approach using rainfall, slope, land use, and soil type parameters which are structured in a hierarchy using the analytical hierarchy process (AHP). Based on the weighted overlay method, it can be concluded that &nbsp;a very potential area for RWH implementation dominated with a wet area, flat slope, dense residential area and the type of soil which is not susceptible to infiltration. Whereas the medium and non-potential areas are dominated by steep and very steep slopes as well as unoccupied land use. Areas of high potential and potential reach 18.17% and 66.14% respectively. While the medium and not the potential is 13.66% and 2.03%. Areas of great potential are in the Buah, Kidul, Sekanak, Sriguna, Bendung, and Selinca Sub Watershed. Non-potential areas are only available in small area in DAS Gandus, Gasing, and Lambidaro Sub Watershed.</p> Imroatul Chalimah Juliana Febrinasti Alia M.

In such conditions, the choice that is often taken is to move the river flow. Displacement of river flows in accordance with the regulations allowed has its own challenges to minimize the risks that will occur to the environment. The aim of the study is to design the basis of a new channel to reduce the speed of the river flow, so that the function and sustainability of river use as an ecological function is not disturbed. The method used is to analyze the origin of the river channel discharge and design the dimensions of the diversion river channel. The results obtained, with forecasts of a 50 year return peak flood period of 104.17 m<sup>3</sup> / sec and with a divergence in the elevation of the diverting river channel of 18.9 m between the planned upstream and downstream along the 6,212.7 m, then to avoid massive scouring at channel base, a maximum flow rate of 10 m / sec and a minimum of 0.8 m / sec with a channel bottom of &nbsp;0.0005% is recommended. For this reason the base profile of the canal is trapped at a distance of 500 m, with an elevation difference of 0.25 m. To maintain ecological sustainability, the dimension of the diversion river channel is maintained the same as the original river, b = 8m, H = 3.5m, and H : V = 1.5: 1.</p> Dinar Dwi Anugerah Putranto Agus Lestar Yuono MA Muzakki Effendi Copyright (c) 2020 Dinar Dwi Anugerah Putranto 2020-06-08 2020-06-08 9 1 47 56 10.35139/cantilever.v9i1.38 Efektifitas Pengendalian Banjir dengan Embung: Studi Kasus Taman Firdaus Universitas Sriwijaya <p>Flood is triggered by a decrease in catchment areas due to an increase in population, activities, and land requirements, both for settlements and economic activities. The flood occurs annually during the wet season at downstream of the campus of Sriwijaya University. In 2019, the downstream swampy land of about 100 ha was excavated and functioned as a retention basin or small reservoir called Embung. The reservoir at Taman Firdaus, Sriwijaya University, was designed by using spillway's top elevation at +5.00m. The objective of the research was to analyze the effectivity of the reservoir on the flood water level of the Kelekar river. One dimensional modelling was used to model the hydraulic routing through small reservoir and Kelekar river. Based on the results of the modeling, it can be seen that the reservoir at Taman Firdaus Universitas Sriwijaya could hold water as much as 1.446.409,39 m<sup>3</sup>, and lower the flood water level in the Kelekar River by approximately 1 to 1.5 meters.</p> Deny Ferdian Anis Saggaff Sarino Copyright (c) 2020 Deny Ferdian, Anis Saggaff, Sarino 2020-07-07 2020-07-07 9 1 57 62 10.35139/cantilever.v9i1.39
