Abstract

A decline in irrigation system performance is generally caused by infrastructure degradation and suboptimal management, which affect the effectiveness of water distribution to agricultural land. This study aims to evaluate the physical and functional performance of the irrigation network in the Gesang Irrigation District in Malang Regency as a basis for determining appropriate maintenance strategies. The research method employed a field survey approach and an irrigation performance index assessment based on parameters including physical infrastructure, crop productivity, supporting facilities, personnel organization, documentation, and the institutional framework of water-user farmers. The assessment was conducted on 33 sections of primary canals through observation of structural conditions and calculation of performance weights. The results of the study indicate that the physical condition of the infrastructure exhibits varying degrees of damage, with the following proportions: Good at 33.33%, Slightly Damaged at 33.33%, Moderately Damaged at 21.21%, Severely Damaged at 9.09%, and Natural at 3.03%. The overall performance score for the physical infrastructure reached 73.16%, which falls into the Moderately Damaged category. The component with the lowest score was the control structures at 67.50%, due to malfunctions in the distribution gates and intake structures. These conditions indicate that water distribution functions are beginning to be disrupted, necessitating rehabilitation at points of severe damage as well as intensive preventive maintenance to ensure the sustainability of irrigation services.

Abstract

The agricultural sector relies heavily on the reliability of irrigation infrastructure to ensure food production stability. This study aims to evaluate the physical performance of irrigation infrastructure in the Santren Irrigation District (DI), located in Jatisari Village, Tajinan Subdistrict, Malang Regency. The Santren IR serves 50 hectares of agricultural land supported by a network of primary canals spanning 2,488.45 meters, secondary canals 198.71 meters, and tertiary canals 167.87 meters. The research method employed was quantitative descriptive, involving an inventory of damage through field surveys and visual inspections of structures and canals. Performance assessment was based on the Irrigation System Performance Index (IKSI) criteria in accordance with Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015, which covers the physical condition of main structures, conveyance channels, control structures, and other supporting facilities. The research results indicate that the physical infrastructure at the Santren Irrigation District is generally in adequate condition. Based on calculations, the total Irrigation System Performance Index (IKSI) score was 85.29%. This score places the performance of the Santren Irrigation District’s irrigation system in the “Still Functioning Well” category. However, several technical issues were identified in the field, such as minor cracks in the concrete wall structures, corrosion on the water gates, and sediment accumulation in the sediment traps and outflow channels, which have the potential to hinder the smooth distribution of water. Based on these findings, it is recommended that the managing authority (the Public Works and Water Resources Agency of Malang Regency) implement more systematic routine maintenance, particularly sediment dredging in sediment traps and functional repairs to corroded floodgate components. In addition, improvements to the quality of inspection roads are necessary to ensure unimpeded operational access and the sustainable monitoring of the irrigation network.

Abstract

The development of Building Information Modeling (BIM) technology has made an important contribution to improving efficiency, accuracy, and data integration in the planning and implementation of construction projects. The application of BIM enables comprehensive visualization of buildings, control of implementation time, and preparation of more measurable cost estimates. This study discusses the application of BIM in the construction project of Melati Husada Hospital in Malang City using Tekla Structures software as the main structural modeling tool. The objectives of this study are to produce a three-dimensional (3D) structural model, integrate the work schedule into four dimensions (4D), and compile a five-dimensional (5D) construction cost estimate. The method used is a case study method using project shop drawing data as the basis for modeling. Modeling is carried out on the main structural elements, including foundations, beams, columns, slabs, and floor plates, in accordance with the building's structural design. The resulting 3D model is then combined with the project implementation schedule to form a 4D construction simulation so that the sequence of work can be visualized in a more planned and systematic manner. In addition, 5D modeling is used to generate construction cost estimates based on the volume of work obtained from the BIM model. The results of the study show that all main structural elements were successfully modeled in 3D. The 4D simulation shows that the project will commence on July 8, 2025, and be completed on December 23, 2025. The estimated cost of structural work includes foundation, sloof, column, beam, and floor slab work, with a total construction cost of IDR 3,215,280,913.

Abstract

The development of Building Information Modeling (BIM) technology has greatly contributed to improving the efficiency of the construction planning and implementation process. This study discusses the application of BIM in the construction project of the Putra Pondok Pesantrean Amanatul Ummah dormitory building in Mojokerto, East Java, using Tekla Structures. The main objectives of this study are to produce a three-dimensional (3D) structural model, create a four-dimensional (4D) implementation schedule, and compile a five-dimensional (5D) cost estimate. This research uses a case study method by processing project shop drawing data, which is then modeled using Tekla Structures. The structural modeling process begins with the foundation, sloof, columns, beams, and floor slabs. The resulting 3D model is then combined with the construction schedule to form a 4D simulation and calculate the cost estimate through 5D modeling. The results of the study show that the modeling of the Foundation, Sloof, Columns, Beams & Floor Slabs (3D) structures has been carried out. From the 4D simulation, the project implementation schedule starts on January 2, 2025, and ends on November 11, 2025. The total calculation of the Cost Estimate (RAB) for the structural work is IDR 3,043,967,282 (three billion forty-three million nine hundred sixty-seven thousand two hundred eighty-two rupiah).

Abstract

The variables affecting this study are the implementation of Occupational Safety and Health (OSH) by PT. Podorukun Nusantara in the Atlantis Hills building construction project in Dau District, Malang Regency. OSH is very important for maintaining a safe workplace, preventing accidents, and increasing worker productivity and efficiency in the construction industry. Employees, managers, and project managers were the 55 respondents who received questionnaires as part of the quantitative methodology of this study. Using SPSS software, the collected data was then examined using multiple linear regression analysis, F and t tests, validity and reliability tests, and more. Safety management variables have a significant impact on OHS implementation, according to the data, but knowledge and implementation factors only partially show a meaningful impact. However, these three elements have a major impact on how well OHS is implemented overall. This study shows that active management participation in policy implementation, worker training, and supervision is crucial in fostering a safety culture in construction projects. It also helps businesses improve worker compliance and awareness of OHS implementation, which reduces workplace accidents.
