Abstract

Muara Enim road segment SP. Sugihwaras very potential to occur landslide based on its location which is on the edge of the river. Recorded by the National Road Implementation Institute (BBPJN) III has been a slope grid in 2014. Slope improvement efforts undertaken by the Ministry of Public Works using a combination of gabion not too successfully overcome the problem. In addition to the strength element of a construction work, the cost and timing of the implementation are also important considerations in planning. Slope at 173 + 535 - Km 173 + 705 along 170 m using soil nailing planned three nails with 19 mmnail diameter and angular slope of 20° with variation of nail length, nail installation spacing, safety factor (SF) and estimated working time to the cost. Using the SPSS.16.0 program, the variations are modeled by nine samples as multiple linear regression equations. Based on the SPSS output, then tested the classical assumption and feasibility test model which produced the model: Cost (million) = - 3159,475 - 54,097 length - 1354,256 distance + 5188,127 SF + 26,483 time. The Budget Plan (RAB) covers preparatory work, drainage system, soil nailing, and shotcrete. An efficient cost estimate of 8 m length nail, 1.5m installation distance, 1.5 safety factor and 64-day working time resulted in a cost of Rp. 3.853.485.500,00 (Three billion eight hundred fifty three million four hundred eighty five thousand rupiah).

Abstract

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.

Abstract

Flood control is one of the prevention methods which involves various engineering sciences and is unique. One of structural flood control methods is retention basin with the goal of containing a certain storm event flow volume and obtaining a specific peak flow reduction. This paper’s objective is to describe how to assess the performance of retention basin physical components quantitatively on seven retention basins in Palembang City. The reference and the parameter used in this research are referred to Drainage Systems Assessment Design (Vadlon, 2011) that is based on Standard Procedure of Retention Basins and Polders Construction according to Public Works Ministry of Cipta Karya Directorate General and the Regulation of Public Work Ministry No.32/PRT/M/2007. The result of the assessment is that there are three retention basins which are in good condition, namely Kambang Iwak Besak (63,9%), Simpang Polda (60,34%), and Kambang Iwak Kecil (56,8%); meanwhile the other four basins are in bad conditions, namely RS. Siti Khodijah (43,01%), Palembang Icon (41,93%), Kemang Manis (7,03%), and Brimob (0,94%). Therefore, the assessment of the retention basins towards its effectiveness on flood controlling and handling priority level is done by hydraulic modeling simulations and GIS. 4. Based on the inundation priority assessment of simulated flood depth and duration, it can be inferred that the retention basin of Kambang Iwak Besak, Kambang Iwak Kecik, Palembang Icon, RS Siti Khodijah, and Kemang Manis have low priority handling level. Meanwhile, Brimob and Simpang Polda retention basins have high priority handling level.

Abstract

Intake structures are facilities for clean water supply situated along riverbanks. These structures are reinforced concrete with pile foundations, and the intake structure comprises a profiled steel frame serving as the upper column-beam framework. The implementation of steel structures demands a high level of precision, particularly in designing connections between sectional steel beams and columns. This study, therefore, aims to determine the optimal dimensions for steel profiles by referring to the design of bolt connections as specified in SNI 1729-2020, particularly for steel beam columns subjected to pump loads and load combinations. The analysis concludes that all three material types meet the safety criteria, with a structural ratio value of ≤ 1 and structural deflection within the allowable limits. Additionally, after assessing the steel column and beam sections' capacity to bear pump loads, it was determined that the optimal bolt connection involved 8 bolts of 24 mm diameter. The ideal supplementary steel plate connection required a plate thickness of 13 mm.

Abstract

Reliable volume estimation and BOQ are indispensable for streamlined construction planning. Errors and omissions in manual calculations and communication result in cost overruns, delays, and ultimately lead to conflicts and disputes among the parties involved in the project. This process is time-consuming and prone to human error. One way to improve efficiency is to implement Building Information Modeling (BIM) in volume estimation and BOQ calculations to enhance work effectiveness. Autodesk Revit is one software that can assist in 3D modeling and accurate volume calculations. This research discusses how BIM can aid in the process of calculating the volume of structural columns and beams for the Main Lecture Hall in the Integrated Agricultural Research and Development Center (P4T). Compared to conventional methods, the research results indicate that the implementation of BIM in this project has provided significant benefits in terms of efficiency, improved calculation accuracy, material usage, and cost savings. With the optimization of concrete usage in structural columns and beams by approximately 26.92% and reinforcement volume by approximately 13.55%, BIM has proven to provide significant added value to the project.

Abstract

The era of the 4.0 revolution has four principles consisting of interconnection, information transparency, technical assistance, and decentralized decision-making. Four principles can be the guidelines for the Building Information Modelling (BIM) system. Government building projects have rules that stipulate that the BIM system must be applied in every construction project. The purpose of this study is to compare the volume of plan and realization work from contractors with conventional methods with plan and realization modeling on pilecap, column, and beam work for concrete and reinforcing work. The method used in this study is to make concrete and reinforcing modeling using Glodon Cubicost TAS and TRB software and use comparative analysis for each work volume result from conventional calculations and BIM modeling results. The data needed consists of general building data, plan drawing data and realization, as well as calculation of the volume of concrete and reinforcement. The results of the study show that there is a varied percentage difference between the data from the contractor and the modeling made, both plans and realization. The use of this software is considered effective if it has been used since the beginning of the construction project, because it can reduce errors and improve the integration between RAB and plan drawings as well as RAP and As Built Drawing.

Abstract

Volume estimation and Bill of Quantities (BOQ) are crucial processes in construction planning. Currently, volume and BOQ calculations are still done manually by calculating the volume of each component in the working drawings. This process is time-consuming and prone to human error. One way to improve efficiency is to implement Building Information Modeling (BIM) in volume estimation and BOQ calculation to enhance work effectiveness. Autodesk Revit is one software that can assist in 3D modeling and accurate volume calculation. This research discusses how BIM can aid in the design volume calculation process and BOQ planning for the Main Lecture Hall building within the Integrated Agricultural Research and Development Center (P4T). Compared to conventional methods, the results show that implementing BIM on this project has provided significant benefits in terms of efficiency, increased calculation accuracy, material usage, and cost savings. With an optimization of concrete material usage by approximately 1,35% and reinforcement volume by approximately 2.11%, and a cost reduction of 0,985%, BIM has proven to provide significant added value to the project.

Abstract

Jambi City IPAL is a new construction which is a container for processing Jambi City's domestic waste. The source of the sludge comes from household wastewater in Jambi City. The sludge produced from the Jambi city wastewater treatment process (IPAL) is dark brown in color and the sludge is floc in nature. District is mud whose grains are separated without coagulants, generally this mud contains sand, grit and small gravel fragments. Mud in the form of floc, namely (chemiflocc) is very large in volume, especially in WWTPs. The XRF results of WWTP mud show high levels of SiO2 and Al2O3, namely 61.56% and 26.93% respectively. The elements contained in cement are found in WWTP mud such as SiO2, Al2O3, Fe, CaO, K2O, MgO, and Na2O. If compared, WWTP mud has the same properties as cement. XRD test results show  crystal phase conditions show peaks with the highest count value at the position [o2Theta] 26.701OH. The SEM mud results show that the grains are in the form of fragments like irregular lumps with varying grain sizes. This condition shows that dry mud has good binding capacity. Jambi City WWTP waste sludge from XRF results has a mineralogical composition similar to cement, because it contains main oxides such as SiO2, Al2O3, CaO, and Fe. Based on its chemical composition, waste sludge has the potential to be used in the production of construction materials after being subjected to combustion treatment.

Abstract

Efforts to change people's behaviors to support the improvement of health status are carried out through the Clean and healthy living behavior (CHLB) development program. Although this program has been implemented by the Ministry of Health in Indonesia since 1996, CHLB implementation has not run optimally. Evaluation of CHLB development's success is carried out by looking at CHLB indicators, one of which is in the school setting. CHLB at school is an activity to empower students, teachers, and the school community to adopt a healthy lifestyle to create healthy schools. This study aims to increase the students' knowledge, attitudes, and actions regarding CHLB in Madrasah Diniyyah, Al Islam Educational Institution, Talang Aur Village, Ogan Ilir Regency, South Sumatra Province.The study uses action research. This activity is carried out by providing communication, information, and education (KIE) regarding CHLB. In addition, we offer knowledge tests about CHLB and demonstrations by practicing how to wash hands correctly and adequately using clean water and soap to increase students' understanding of CHLB activities. This study emphasizes the importance of socializing clean and healthy life early through integrating learning programs in schools. The results showed an increase in the target audience's knowledge, attitudes, and actions about CHLB. The benefits of CHLB in schools include creating a clean and healthy environment, improving the teaching, and learning process, and making students, teachers, and the school environment healthy.
