Abstract

This study designs a rainwater drainage system for Hospital X to prevent water stagnation and maintain optimal sanitation conditions. Field surveys and hydrological data, including rainfall data from the Karangploso Rain Station, were analyzed to determine the peak runoff and the required drainage channel capacity. The hydrological analysis resulted in a 5-year return period design rainfall of 107.54 mm using the Log-Normal distribution. Hydraulic calculations indicate that surface concrete drainage channels are the most suitable option, given the soil conditions and flow requirements. The drainage channel design was calculated using the rational method to determine the channel dimensions, resulting in three standard channel types: S1 (height 0.4 m and width 0.3 m), S2 (height 0.7 m and width 0.5 m), and S3 (height 0.9 m and width 0.6 m). This system has sufficient capacity to convey peak runoff without causing flooding, thereby improving the safety and operational comfort of the hospital. Future research is recommended to integrate wastewater management into the drainage design, so that rainwater and hospital wastewater can be managed in an integrated manner, safeguarding environmental health and meeting sanitation standards.

Abstract

The Curve Number (CN) method is widely used to estimate surface runoff in watershed hydrology. This study aims to estimate the CN value of the Konaweha Watershed using remote sensing and spatial analysis approaches. Sentinel-2 satellite imagery was utilized to derive land cover information, while soil type data from the Food and Agriculture Organization (FAO) were employed to determine the Hydrologic Soil Group (HSG). The analysis was carried out on the Google Earth Engine (GEE) platform by integrating the land cover map derived from Sentinel-2 classification with the HSG map obtained from FAO soil data. CN values were assigned based on the Soil Conservation Service (SCS) method by linking land cover classes and soil groups. The results indicate that the Konaweha Watershed is dominated by forest and agricultural land cover, with a heterogeneous distribution of HSG. The integration of both datasets produced a spatially distributed CN map with an average value of 52.6, reflecting the hydrological condition of the watershed with relatively good infiltration capacity and moderate surface runoff potential. The findings provide valuable input for hydrological modeling and water resources management planning. This study demonstrates that the integration of Sentinel-2 satellite imagery and FAO soil data through GEE offers a fast, efficient, and reliable approach for CN estimation at the watershed scale.

Abstract

River abrasion is a natural disaster that causes land erosion due to strong water currents or waves, leading to significant impacts on human settlements and land use. This study analyzes the extent of land loss and changes in settlement patterns caused by river abrasion in Muara Sampara Village, Kapoiala District, Konawe Regency, from 2014 to 2024. Using a Geographic Information System (GIS) approach with high-resolution satellite imagery, overlay analysis was conducted to determine the spatial dynamics of land use and the extent of areas affected by abrasion. The results show that the total land area of the village decreased by 3.23 hectares over ten years, with the highest rate of abrasion occurring between 2016 and 2018. The analysis also indicates a gradual shift in settlement patterns from riverbanks toward safer central areas of the village, reflecting community adaptation to environmental changes. These findings provide crucial spatial information to support local government policies on riverbank management, disaster mitigation, and sustainable land use planning

Abstract

Indonesia remains committed to prioritizing national infrastructure development in an effort to boost regional economic growth. Proper optimization of funds is necessary, given the high maintenance costs. Thus, proper procedures and systematic implementation are essential. To achieve the best results, a bridge management system is needed. However, in its application, the bridge management system in Indonesia still faces assessment challenges (bias) that can affect the results. Therefore, several approaches are needed to complement development and provide input. To evaluate the assessment system in the 2022 Bridge Inspection Guidelines, this study aims to adopt the Bridge Health Index (BHI) method. This study attempts to identify the advantages and disadvantages of both approaches, which are expected to contribute significantly to the development of bridge management systems in Indonesia. Based on the results of the analysis, the BHI method provides a priority order for handling based on bridge condition values, while for the 2022 Guidelines, the priority order cannot yet be determined because there is still a bias between the condition values of one bridge and another, so further analysis is needed. Based on the comparison results, damage to the core elements of the bridge will be prioritized when these elements are weighted. The ranking results can be made clearer by using a numerical assessment range and a weighting scheme, which reduces bias. This perspective is important to provide input for developers and contribute to the growth of Indonesia's bridge management system in the future.

Abstract

Shear failure is recognized as a brittle and sudden collapse mode, making it a critical issue that necessitates effective strengthening solutions for reinforced concrete beam structures. The main objective of this study is to evaluate the effectiveness and feasibility of Glass Fiber Reinforced Polymer (GFRP) composite as external reinforcement to address the shear strength deficit in reinforced concrete beams. The case study focuses on the West Tribune beams of GOR Barombong Makassar, which experienced shear failure due to a combination of low material quality, exposure to an aggressive marine environment, and increased capacity demands resulting from the seismic standard update from SRPMM to SRPMK. The research methodology utilized analytical calculations based on the ACI 440.2R-08 guidelines. Analysis results indicate that the existing shear strength of the beams is 424.23 kN, while the required additional strength varies from 21.57 kN to 53.93 kN to meet the design shear strength. Six GFRP U-Wrap strengthening configurations were analyzed, demonstrating the capability to provide additional shear strength ranging from 26.68 kN to 55.31 kN. The application of a specific GFRP configuration at the beam supports successfully increased the total shear capacity by 6.3% to 13.0%, proving that GFRP is an effective and efficient shear strengthening solution, and is superior due to its non-corrosive properties, making it suitable for aggressive environments.
