In this paper, a study was conducted to analyze the influence of variations of steam curing temperature (SCT) and water/binder (w/b) ratio on the characteristics of SCC incorporating 10% Palm Shell Ash (PSA) as a partial substitution for cement mass. The SCT was arranged from 25 &nbsp;C to 80 &nbsp;C. The variation of w/b in the compositions of SCC was 0.325, 0.350, and 0.375. The results showed that using PSA, the variation of SCT and the w/b ratio influenced the workability of the fresh concrete. The PSA, SCT, and the w/b ratio affected the concrete compressive strength and mass density. The increased SCT caused a lighter density and greater compressive strength. However, the decreased compressive strength occurred due to an excessive SCT of 70 &nbsp;C and above. The SCT of 60 &nbsp;C, 10% PSA, and w/b ratio of 0.350 in the mixture produced the greatest compressive strength of 36.27 MPa at 28 days of age, while without SCT, the greatest compressive strength of 36.78 MPa was achieved at the age of 28 days containing 10% PSA and w/b ratio of 0.325. It indicated that the w/b ratio was more influential than the SCT on the increase of the SCC compressive strength.</p> Siti Aisyah Nurjannah Sutanto Muliawan Ervi Tri Romayni Nurazizah Dwi Asmarani Copyright (c) 2024 Siti Aisyah Nurjannah 2024-05-18 2024-05-18 13 1 1 12 10.35139/cantilever.v13i1.235 Evaluasi Faktor-Faktor Penyebab Longsor dan Kesesuaian Mitigasi <p>Management and maintenance of slopes require proper knowledge of slope conditions so that appropriate mitigation measures can be implemented. The activities required for the management of slopes include slope inventory, slope inspection, slope risk level assessment, and risk mitigation measures. The objective of this study was to observe the slope conditions and causes of past slope failures, determine the appropriate mitigation measures, and analyze the suitability of landslide mitigation measures and causes of slope failures. The research locations are road segment No. 36 (Kota Lahat – Simpang Air Dingin), No. 37 (Simpang Air Dingin – Pagar Alam), and No. 38 (Pagar Alam – Tanjung Sakti – batas Bengkulu). The research was initiated by analyzing data collected by the South Sumatra National Road Management Agency (BPJNSS) from 2018 to 2021. The field observation was conducted on ten locations where the slope had been repaired after slope failure events. The suitability of mitigation with the factors that cause landslides was analyzed using the slope management system method suggested by the Ministry of PUPR. The results showed that most slope failures were triggered by high-intensity rain falling on slope surfaces containing high humidity due to previous rainfall. The common types of slope mitigation are reducing the forces that cause movement, increasing the resisting forces by controlling seepage, and the use of anchors.</p> Bulkin Fathoni Erlangga Saputra Nurly Gofar Copyright (c) 2024 Bulkin Fathoni, Erlangga Saputra, Nurly Gofar 2024-05-18 2024-05-18 13 1 13 22 10.35139/cantilever.v13i1.261 Analisis Produktivitas Alat Berat dalam Pengelolaan Sampah di Kecamatan Sukarami Kota Palembang <p>In Indonesia, solid waste has become a problem for municipalities, which could result in hygienic and aesthetically unpleasant issues. The high rate of population growth will have an impact on waste generation since it will change the needs and lifestyles of city dwellers. The collection, transportation, and final disposal of urban solid waste (TPA) require suitable facilities and infrastructure, particularly hefty equipment. Heavy equipment, specifically waste trucks, and heavy digging equipment, plays a significant part in supporting waste management activities. In particular, the Palembang City region is covered in this study's discussion of the productivity of heavy machinery used in waste management, which might begin with the collecting system, transportation system, and heavy equipment employed at the landfill. The study was conducted in Palembang City's Sukarami District, and data was collected by surveying and observing the current condition of the heavy equipment that was already in place, namely in terms of cycle time variables and the volume of waste that was served. The findings of the study indicate that direct communal and direct individual patterns characterize the region's waste-collecting practices. Dump trucks, which are used to transport waste, had a productivity range of 609.98 to 1266.13 kilograms per hour, while bulldozers and excavators had a range of 759.42 to 1166.17 kilograms per hour. This heavy equipment repair recommendation is targeted at bulldozers and excavators since a field investigation reveals that there are now only 2 pieces of bulldozer heavy equipment and 1 unit of excavator heavy equipment available.</p> Ani Firda Akhirini Rosmalinda Permatasari Copyright (c) 2024 Ani Firda, Akhirini, Rosmalinda Permatasari 2024-05-18 2024-05-18 13 1 23 30 10.35139/cantilever.v13i1.270 A Review of Recent Developments on Modeling Low Impact Development (LID) Technique <p>Urban areas are more susceptible to flooding and water body contamination due to the detrimental effects of urbanization. As a result, a sustainable urban drainage system, also known as low impact development (LID) technique, is required. Although this technique can be extensively applied, the planning and design processes are multi-dimensional, multi-variable, and site-specific, which must consider various local conditions and factors. Consequently, these processes can be very complicated and time-consuming for professionals, necessitating support from computer modeling. This study intends to thoroughly explore the idea of LID modeling, various available computer models, and other tools for its optimization and decision-making processes. The most recent trustworthy journal publications that addressed the subjects under discussion were reviewed. This paper used the descriptive and comparative approaches as the analytical methods. According to the findings of the review, Storm Water Management Model (SWMM) is the computer model in LID modeling that is most frequently employed. This model is a fundamental package for dynamic urban rainfall-runoff modeling, and it has the benefits of being lightweight, simple to use, and an intuitive user interface. Besides, this model is public domain (free to use), open source, and interoperable with many hydro modeling applications. A specific LID editor module is also included in this model for modeling different LID units. To acquire the best LID planning and design from multiple criteria and alternatives, it is also necessary to use metaheuristic algorithms as an optimization model and a multi-criteria decision-making (MCDM) model in addition to the rainfall-runoff model. The authors believe combining the hydrologic and hydraulics models integrated with geographical information systems (GIS), metaheuristic algorithms, and MCDM is the most comprehensive and appropriate method for LID modeling in urban watersheds.</p> Muhammad Baitullah Al Amin Joko Sujono Radianta Triatmadja Copyright (c) 2024 Muhammad Baitullah Al Amin, Joko Sujono, Radianta Triatmadja 2024-05-18 2024-05-18 13 1 31 44 10.35139/cantilever.v13i1.320 Penelusuran Debit Anak Sungai Musi Berdasarkan Pengukuran Curah Hujan Kota Palembang <p>The hydrological cycle of the South Sumatra region is influenced by the potential flow produced by the Musi River and its tributaries. The quantity of water that is accessible at any given place is never constant and varies with time. The primary input to the river basin simulation model is flow and discharge data, which must be a time series that completely captures the variability of river flow and discharge data in order to accurately depict water availability. Because the Sekanak River is one of the tributaries of the Musi River, the research built a hydrological model that combines rainfall and river discharge to determine the discharge. The monthly rainfall data is processed to obtain the average rainfall during the data analysis step. The modified Penman method is then used to calculate evapotranspiration. The FJ Mock model was used to examine the mainstay discharge. Results of the discharge analysis for the period of 2018 to 2022 using the FJ Mock method show that the largest discharge occurred between March and June, ranging from 0.203 to 0.241 m<sup>3</sup>/sec. When the calculated discharge and the actual discharge are compared, it can be seen that the minimum discharge happens in August and the maximum discharge typically occurs in March in the actual discharge data.</p> Rosmalinda Permatasari Reni Andayani Zuul Fitriana Umari Copyright (c) 2024 Rosmalinda Permatasari 2024-05-18 2024-05-18 13 1 45 54 10.35139/cantilever.v13i1.286 Analisis Ketersediaan dan Kebutuhan Air Sub DAS Rupit Menggunakan Remote Sensing dan GIS <p>The water balance of a river basin is crucial for estimating water availability to meet current and future domestic and economic water demand and supply. Parameters such as rainfall, temperature, evapotranspiration, deficit, and surplus soil water content determine the water availability of a river basin (DAS), influenced by factors like land use, soil type, seasonal variations, and other environmental factors. This research aims to estimate the water balance of the Rupit sub-watershed using the FJ Mock model. The Sentinel 1 image of the area was processed to produce a land use map. GIS modeling generated maps of rainfall, land use, soil, slope, morphometry catchment, excess moisture, evapotranspiration, and surface run-off. The analysis reveals that the highest rainfall and evapotranspiration occur in January, while other months average around 56 - 66 mm per month. Excess water during the wet months (November-March) leads to flooding, damaging infrastructure such as residential buildings, roads, and bridges. Conversely, April-October experiences water shortages. The annual weighted watershed deficit is 46.6 mm, with almost no surplus detected. Rainfall run-off simulations demonstrate significant and coherent watershed responses to rainfall patterns. Due to low rainfall and soil moisture levels from preceding months, March exhibits the highest discharge at 15.35 m<sup>3</sup>/s, with a run-off coefficient of 0.863.</p> Nurhikmawaty Dinar Dwi Anugerah Putranto Febrian Hadinata Copyright (c) 2024 Nurhikmawaty, Dinar Dwi Anugerah Putranto, Febrian Hadinata 2024-06-10 2024-06-10 13 1 55 64 10.35139/cantilever.v13i1.316
