Abstract

Water demand always increases rapidly, which is in line with the increase in population over time. One alternative for providing fresh water is groundwater usage. Klampok Village is one village affected by freshwater problems, especially during the dry season. The current solution in the form of water supply from the government is still insufficient to meet the water needs of residents, most of whom work in the agricultural and plantation sectors. This problem can be overcome by searching for new groundwater locations using geoelectric methods. The geoelectric method utilized the Schlumberger configuration and Vertical Electrical Sounding (VES) to conduct a field test. Field test results were then processed using IPI2Win. The Root-Mean-Square (RMS) result was 1.94% by identifying eight layers. The research finding is resistivity values of 11.38 - 2167 with a depth of 100 meters.

Abstract

Good road conditions are critical in ensuring the comfort, safety, and efficiency of road users' journeys. The Pandaan–Malang Toll Road, as a strategic infrastructure with a traffic volume of 43 million vehicles per year, faces challenges related to the degradation of road surface quality due to traffic dominated by light vehicles. However, previous studies have not extensively integrated the relationship between vehicle volume and the International Roughness Index (IRI) values on a segmental basis as a basis for maintenance evaluation. This study aims to analyze the IRI conditions of five segments of the Pandaan–Malang toll road during the period 2022–2024 and recommend maintenance strategies based on IRI classification in accordance with Ministry of Public Works and Public Housing Regulation No. 47 of 2015. The method used is quantitative with secondary data analysis of IRI values from PT Jasa Marga Pandaan–Malang based on RoadRoid Survey Application and processed using Microsoft Excel. The results show that the average IRI value in 2024 is 3.66, classified as Good, but Segments I and II classified as Fair with values >4 and require periodic maintenance. Other segments can still be maintained through routine maintenance. This study concludes that the IRI values show a stable trend but have the potential to increase without planned maintenance. Future research is recommended to examine the integration between IRI, PCI, and traffic load to develop a more comprehensive and applicable road damage prediction model.
