Abstract

Pemda Road in Kapur Village, Sungai Raya District, Kubu Raya Regency, West Kalimantan is a district road that functions as an alternative route connecting Tanjung Raya II Road and Kapur Village Main Road. Along with increasing traffic loads and limited maintenance, this road section has experienced various surface pavement distresses that reduce driving comfort and compromise road safety. This paper seeks to detect the types and severity levels of pavement damage and to determine appropriate preservation actions using the Pavement Condition Index (PCI) method. The research method involved a visual field survey by dividing the road into several segments, identifying damage types and severity levels, calculating PCI values, and determining suitable preservation measures based on the Asphalt Institute MS-17 guidelines. The results indicate that the flexible pavement section has a PCI value of 21.643, classified as very poor, with dominant damages consisting of potholes and edge cracking. Meanwhile, the rigid pavement section shows a PCI value of 94.960, which falls into the excellent category. The results of this research are anticipated to facilitate decision-making in determining maintenance priorities and road preservation strategies to improve pavement performance and extend service life.

Abstract

This study aims to analyze the effect of Tungsten Inert Gas (TIG) welding parameter variations on the mechanical and metallurgical properties of AISI 304 austenitic stainless steel, which is widely used in construction and industrial applications due to its excellent corrosion resistance and joint strength. The research focuses on identifying the optimal welding current to minimize welding defects and enhance joint structural integrity. Welding current was varied at three levels, namely 100 A, 125 A, and 135 A, while other parameters such as welding speed, argon shielding gas flow rate, and electrode type were kept constant. Mechanical properties were evaluated through Micro-Vickers hardness testing conducted in the weld metal, Heat Affected Zone (HAZ), and base metal, as well as tensile testing to determine ultimate tensile strength and elongation. In addition, non-destructive testing using the dye penetrant method was performed to detect surface welding discontinuities. Metallographic analysis was carried out using optical microscopy following an etching process to observe grain morphology, grain size, and the formation of microstructural phases. The results are expected to demonstrate a correlation between increased heat input due to higher welding current and changes in mechanical properties and microstructure, particularly in the HAZ. This study provides practical guidance for determining optimal TIG welding parameters for AISI 304 to achieve high tensile strength, homogeneous hardness distribution, and a stable microstructure resistant to intergranular corrosion.

Abstract

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.

Abstract

The energy that is stored in water can be used to generate electricity by taking advantage of the potential energy available, like the energy from waterfalls and the movement of flowing water. Micro-hydropower plants (PLTMH) are one solution to address the energy crisis, particularly in electricity. VDI 2221 is a method that German engineers use as a guideline when designing construction projects. The VDI (Verein Deutsher Ingeneure or German Engineers Association) design process involves several stages: task description, design concept determination, physical design, and detailed design. Based on the solution principle matrix table, 3 variants were obtained, each of which has criteria. Of the 3 variants that have been evaluated, variant 2 was obtained with results that met the requirements. The cost analysis table shows that the total cost for designing a prototype test equipment for a micro-hydroelectric power plant (PLTMH) based on a laboratory-scale crossflow turbine is Rp 10,032,000. This cost includes instrumentation, control and electrical panels, measuring instruments, pipe instruments, frame and casing, and unforeseen costs.

Abstract

Gas turbine generators play an important role in providing electrical energy, especially in the maritime sector, but they are vulnerable to disturbances such as overcurrent and undervoltage, which can cause equipment damage. This study aims to design and test an automatic protection system based on the ESP32 microcontroller with the INA219 sensor to detect current and voltage, as well as a relay as a circuit breaker. The method used is an experimental approach including static and dynamic testing, both with and without a 5W AC lamp load as a simulation of real loading conditions. Test results show that the average sensor reading error is 2.65% for current and 1.76% for voltage, which is still within the ±3% tolerance limit. The system is able to disconnect the load when any parameter exceeds the protection threshold, although there are slight inconsistencies in the relay response due to sensor reading fluctuations. In conclusion, this automatic protection system is proven to be 85% accurate and responsive in maintaining the operational reliability of the gas turbine generator, making it applicable as a preventive solution against electrical disturbances in marine environments.

Abstract

This study aims to test the effectiveness of the implementation of a simplified Mini-QHSE (Quality, Health, Safety, Environment) system in improving working conditions at the Syams Handicraft woven craft MSME in Pati Regency, Central Java. The study used a quantitative method with a one-group pretest–posttest design involving 47 workers as respondents. Data collection was conducted through questionnaires and observations before and after the twelve-week intervention. The results showed that the implementation of the Mini-QHSE system was able to significantly reduce the level of occupational safety and health risks and significantly improve worker welfare. Further analysis revealed that the Mini-QHSE system made a significant contribution to variations in OHS risks and worker welfare. The dimension of safe work procedures proved to be the most influential factor in reducing work risks, while the training aspect was the main factor in improving worker welfare. Based on these findings, it can be concluded that the Mini-QHSE system designed according to the capacity and characteristics of MSMEs is effective in creating a safer and more prosperous work environment. This model has the potential to be applied to similar MSMEs with contextual adjustments as a practical solution in managing quality, safety, and occupational health in the micro-business sector.

Abstract

Lifting activities are an essential part of manual material handling across various industrial sectors and constitute a primary source of ergonomic risk exposure when performed with inappropriate work postures. The use of hands-off tools such as push-pull sticks is often implemented to maintain a safe distance between workers and loads and to reduce exposure to line-of-fire hazards. However, the implementation of work aids does not automatically ensure neutral work postures, as push-pull techniques, reach distances, and environmental conditions can still lead to awkward postures. This study aims to evaluate the work posture risk in lifting activities using a fiber-composite push-pull stick based on the Rapid Entire Body Assessment (REBA) method. The research was conducted as an observational analytic field study involving nine workers in tubular pushing and pulling activities. Work postures were documented through direct observation and visual recordings, then assessed using REBA to obtain risk scores, risk categories, and required corrective actions. The results indicate that work postures fall into the medium to high-risk categories, with trunk and shoulder components being the dominant contributors. These findings confirm the need for improvements in work methods, ergonomic training, and strengthening of lifting SOPs to optimize the safety and ergonomic benefits of work aids.
