Abstract

The demand for construction materials, particularly for pavement construction, continues to rise, leading to a reduction in available material resources. To address this, an alternative approach has been developed by utilizing marble powder waste as a partial substitute for fine aggregate in rigid pavement construction. This study employs a quantitative, experimental research design aimed at determining the compressive and flexural strength of concrete when marble powder is used as a partial replacement. The compressive strength tests involved varying the marble powder content at 0%, 15%, 25%, and 35%, with assessments at both 7 and 28 days, targeting a planned concrete quality of fc' 21,7 MPa. The compressive strength values at 7 days for each variation are as follows: 0% (13,06 MPa), 15% (13,98 MPa), 25% (15,99 MPa), and 35% (14,10 MPa). At 28 days, the compressive strength results were 0% (22,00 MPa), 15% (23,79 MPa), 25% (16,97 MPa), and 35% (15,67 MPa). For the flexural strength tests, marble powder was substituted at levels of 0%, 15%, 25%, and 35% in concrete specimens measuring 12x50x120cm, with the load applied at 28 days. The maximum load recorded for each variation was 0% (4300 kg), 15% (3200 kg), 25% (4000 kg), and 35% (2500 kg). The average deflection observed was 0% (3,93mm), 15% (2,60mm), 25% (4,26mm), and 35% (2,37mm).

Abstract

Rainfall data is one of the important initial inputs in hydrological analysis, but it is often incomplete due to various constraints such as damage to measuring instruments or uneven distribution of measurement stations. To overcome this problem, weather observation with satellites can be used. However, before using satellite rainfall data, it is necessary to test its suitability with field data to ensure its accuracy. This study aims to evaluate the PDIR-Now satellite rainfall data on observation rainfall data in Serang City to determine the feasibility of using satellite rainfall data and the influence of rain periods (daily (>50mm/day), 15 days, and monthly) on the reliability of satellite data. The analysis method in this study uses statistical analysis in the form of regression analysis at the calibration stage and RMSE, NSE, and Pearson (r) correlation coefficient at the validation stage. Based on the results of the study , it is known that the PDIR-Now satellite can estimate the best rainfall in the monthly period.

Abstract

The building of the Teaching Hospital at Jambi University has stopped until now with the current development of physical development in the form of the upper structure work stage of the building. To be able to resume the physical construction of the RSP UNJA building, it is necessary to have a technical study in the form of an evaluation of the building's current structural state, to ensure that the existing structure has good strength and is feasible to continue the stages of work until it is completed according to planning. The technical standards used by the planning consultant in its 2015 planning used old standards, while the standards used have been updated with the latest technical standards. Building planning data and existing data on completed work are gathered as part of the evaluation approach employed in this study, then an analysis is carried out based on the latest standards. The analysis's findings indicate that while all floor slab structure elements at every level satisfy the requirements for moment strength and shear force, some beam elements in specific locations do not, and all column types satisfy the requirements for axial strength but some column elements in specific locations do not meet the requirements for shear force strength. From the results of the analysis and conclusions, it was obtained that some of the existing structures meet the strength requirements which means that they can withstand the load of the working service.

Abstract

One issue that might lead to environmental disturbances in Indonesia's varied areas is solid waste. It is possible to execute waste management effectively, and one such implementation is the installation of waste transportation. If waste transportation fleet is unable to handle the current waste generation, which may result in waste accumulation, then the problem of transporting waste may arise. In order to address this issue, assistance is required in the form of waste transportation costs. In accordance with the local conditions at the time of the study, this paper analyzes the calculation of waste transportation fees. The collection of information was done to determine how waste transportation was currently operating, including the number of vehicles, the distance that went, their rotation, and their carrying capacity. According to the study's findings, the cost of garbage transportation is Rp. 3,277/km or Rp. 21,257/m3 for armroll trucks and Rp. 5,980/km or Rp. 86,459/m3 for dump trucks. These findings show that the fee for Armroll trucks is higher than the levy for dump trucks. This is because Armroll vehicles have a longer service route and use more fuel.

Abstract

Road safety is a topic that is often raised, and is currently a world concern that not only affects transportation but also society. Therefore, it requires an analysis of road safety in terms of the completeness of road infrastructure to meet the standard value of the Indonesian Road Capacity Guideline. and the National General Plan for Road Traffic and Transportation Safety (RUNKLL). The purpose of the study was to determine the accident-prone points on the Krebet-Bululawang highway, Malang Regency. and provide handling efforts related to the results of the Krebet Highway Safety Analysis in Review from the Completeness of Road Infrastructure Aspects. In this study, what is calculated is the Z-score Technical Analysis of accident-prone areas (Black sites), the Cusum Technique of accident-prone points (Black Spot). Based on the results of accident characteristic data processing, the location of accident-prone points (black spots) that have the largest custom value on Jalan Krebet is identified as accident-prone points in segments 1 and segment 3 as the cause of having the largest custom values, namely 7,200 and 5,250. Based on the accident data, the accident z-score values for each segment were obtained based on the total number of accident incidents during the period 2018 - 2022 with 2 road segments with the highest scores, namely segments 1 and 3 where the number of accident victims was 11 accident victims and the highest z-core value was 2.012 in segment 1 and segment 3 0.224 Identify characteristics that are deeper and more detailed, this is based on the results of analysis of accident z-score values that appear 2 priority road segments and aim in efforts to handle accident-prone segment location points that have been identified and determined previously. At this stage, the most important technical problems in road traffic safety will be described as Proposed Handling for accident-prone areas (black sites) and accident-prone points (back spots) that need to be installed warning signs for dangerous areas where accidents often occur. Usually the placement of these traffic signs is at least 50 meters before areas where accidents often occur according to the standard of RI transportation regulations No PM 13 2014 concerning traffic signs.

Abstract

More than 90% of aggregate is used in asphalt mixtures, meaning the type of rock used as aggregate must comply with permitted specifications. Igneous rocks, as one type of rock, are often used in road construction. Aggregates found in various sources indicate that they possess different characteristics. The resistance of aggregates to polishing demonstrates their ability to support better skid resistance. This study aims to determine the polishing resistance of aggregates by comparing two types of aggregates from different sources (aggregate-1 and aggregate-2). The testing method was conducted in a laboratory, referring to the 2018 Bina Marga and British standards. The equipment includes the polishing Stone Machine and the British Pendulum Tester (BPT).The results showed that both aggregates are suitable for asphalt mixture materials. However, the polishing resistance test results for aggregate-2 (28 BPN) were higher than aggregate-1 (26.4 BPN) because the surface texture of aggregate-2 is coarser, with larger pores, making it rougher. Based on the polishing resistance test, aggregate-1 had longer resistance (65.35%) than aggregate-2 (61.74%) because aggregate-1 is harder than aggregate-2; this can also be observed from their property test results.In conclusion, aggregates from different sources have distinct characteristics and polishing resistance.

Abstract

The Indonesian Government through the Minister of Public Works and Housing has recently issued Regulation Number 10 of 2021 concerning guidelines for the Construction Safety Management System (SMKK). This regulation must be implemented during construction as it is part of project planning and control. The objectives of this research are to analyze the level of influence of PUPR Ministerial Regulation No.10 of 2021 on improving SMKK implementation in the basement construction project of the Great Mosque of Serang City, to identify hazards that can cause accidents in the construction work, and to determine control action plans to reduce the risk level of accidents in the Serang City Grand Mosque basement construction work. The conclusion is that PUPR Ministerial Regulation No. 10 of 2021 concerning SMKK has a significant impact. This regulation emphasizes the importance of work safety in construction projects, including the Serang City Grand Mosque basement construction. By using the Hazard Identification, Risk Assessment, Risk Control Determination, and Opportunity (IBPRP) method, potential hazards can be identified for each type of work. The identification of work risks assessed with low risk level is 23 types of work (32.41%), medium risk level is 39 types of work (54.92%), and high risk level is 9 types of work (12.67%) from a total of 71 work risks. From the analysis of risk control identification using the IBPRP table, one high-risk level work was selected, namely the first floor structure work with the sub-work of formwork dismantling and risk identification of scaffolding collapse. The risk controls identified are using support pipes to strengthen the scaffolding and installing 2-layer railings on the scaffolding, conducting toolbox meetings, safety induction, job training, and ensuring the scaffolding is safe to use, and using PPE (safety shoes, safety helmet, vest, long-sleeved work clothes, gloves, and full body harness).
