Abstract

The construction of health facilities is part of national development. Therefore, many health facility development projects, such as hospitals, continue to be carried out in various regions. One of them is the construction of the New Siloam Hospital in Surabaya. This article aims to understand the concept of detail engineering design on the building structure of New Siloam Hospital. Field surveys and data collection are the methods used to obtain information related to hospital construction projects. There are several differences between field data and work drawing data that has been created. Some of these differences include details on the reinforcement and casting volume. Therefore, it is necessary to carry out further evaluation of field data with work drawing data so that the project can proceed according to initial planning.

Abstract

Rapid population growth in Sidoarjo Regency has triggered massive land-use changes, resulting in increased surface runoff and reduced performance of the drainage system. This study aims to evaluate the hydraulic capacity of drainage channels in the Pondok Sidokare Indah Housing area against design flood discharges with return periods of 2, 5, and 10 years. The method used is a descriptive quantitative approach, involving hydrological analysis using maximum daily rainfall data from 2015–2025 and hydraulic modeling of the existing channel along 350 meters. The frequency analysis results indicate that the Log Pearson Type III distribution is the most suitable method based on statistical parameters and the Smirnov-Kolmogorov goodness-of-fit test. The calculation of design flood discharge using the rational method yields values of 0.749 m³/s (2-year), 1.003 m³/s (5-year), and 1.164 m³/s (10-year). Meanwhile, the maximum capacity of the existing channel ranges only between 0.534 m³/s and 0.733 m³/s. The comparison between hydrological load and channel capacity shows that all observation points (Sta 0+000 to Sta 0+350) are in overflow condition, even for the lowest return period flood discharge. This condition confirms that the current channel dimensions are no longer adequate and require normalization to mitigate annual flooding in the area.

Abstract

Groundwater serves as the primary source of domestic water for many rural communities in Indonesia. However, increasing anthropogenic activities and environmental changes may alter groundwater quality, making periodic chemical quality assessment essential to ensure its suitability as a raw water source. Information regarding groundwater quality in Dusun Tambak Agung, Tanah Merah Laok Village, Bangkalan Regency, remains limited. Objective: This study aimed to evaluate the chemical quality of shallow groundwater as a raw water source based on the Regulation of the Indonesian Ministry of Health No. 2 of 2023. Methodology: A quantitative descriptive approach was employed by collecting groundwater samples from seven representative household wells. The samples were analyzed in an accredited laboratory to determine pH, nitrate (NO₃⁻), nitrite (NO₂⁻), hexavalent chromium (Cr⁶⁺), iron (Kristanto et al.), and manganese (Mn). The analytical results were compared with national drinking water quality standards, followed by groundwater suitability classification using the Sturges scoring approach and spatial evaluation through Geographic Information System (GIS). Findings: The laboratory analysis revealed that all groundwater samples complied with the established quality standards for the analyzed chemical parameters. Neutral pH values and relatively low concentrations of nitrate, nitrite, chromium, iron, and manganese indicate that the investigated groundwater is chemically suitable for use as a raw water source. The findings also suggest that groundwater quality in the study area is predominantly influenced by favorable hydrogeological conditions with limited evidence of anthropogenic contamination. Implications: The findings provide scientific evidence for groundwater resource management and support local governments in implementing routine groundwater quality monitoring, groundwater protection measures, and sustainable water resource planning in rural communities. Originality: This study provides updated baseline information on groundwater chemical quality at the village scale by integrating standardized laboratory analysis, groundwater suitability assessment, and GIS-based spatial evaluation. The proposed approach contributes practical knowledge for sustainable groundwater management and environmental decision-making in rural Indonesia.
