The application of food hygiene and sanitation principles is an important aspect in ensuring the quality of nutritional services in hospitals. Low compliance of kitchen staff in maintaining hygiene is often caused by a lack of supervision, motivation, and limited supporting facilities. This study aims to determine the effect of education on compliance with the application of food hygiene and sanitation and its contributing factors in the Nutrition Installation of Hospital X through an internship activity conducted in July–October 2025. The research method used a quasi-experimental model with a one-group pretest-posttest and a mixed methods approach. The research subjects were seven kitchen staff, with two of them being interviewed in depth via voice recording. Data collection was carried out through initial observations, compliance checklists, and recorded interviews at the pretest and posttest stages. Educational interventions were carried out through counseling, routine briefings, and mentoring in the six-step handwashing practice according to WHO guidelines. Data analysis was carried out using descriptive quantitative and thematic qualitative methods. The results showed an increase in staff compliance after being given education, seen from changes in behavior in washing hands properly, using personal protective equipment, and maintaining cleanliness of the work area. Based on pretest interview results, low compliance was caused by a lack of supervision due to the lack of accreditation, infrequent monitoring, the misperception that visibly clean hands were safe enough, and limited water supply due to the shared drain with the hospital laundry. Following the educational intervention, posttest results showed improved compliance compared to baseline.

This study analyzes the impact of urban sprawl on groundwater reserves in Kendari City using the platform Google Earth Engine (GEE) with analysis period of 2000 and 2024. Urban sprawl is characterized by an increase in built-up land area estimated through the Normalized Difference Built-Up Index (NDBI), while groundwater reserves are projected through estimated baseflow groundwater runoff obtained from FLDAS ( Famine Early Warning Systems Network Land Data Assimilation System ) data. The results show a significant increase in NDBI values from 2000 to 2024, indicating a massive expansion of built-up areas. Conversely, baseflow values have decreased consistently, with the average baseflow decreasing from 0.00002685 kg/m²/s (2000) to 0.00001894 kg/m²/s (2024), reflecting pressure on the aquifer system due to reduced infiltration areas. Pearson correlation analysis revealed a significant weak negative effect between NDBI and baseflow in 2000 (r = -0.219; p-value = 0), which changed to a weak positive effect in 2024 (r = 0.126; p-value = 0), indicating a shift in hydrological dynamics due to the accumulated impacts of urbanization. This finding confirms that urban sprawl has reduced groundwater recharge capacity and threatened the sustainability of clean water supplies. The study recommends the need for sustainable spatial planning policies and groundwater conservation strategies to mitigate these negative impacts.

As an archipelagic country, Indonesia has significant potential for the utilization of renewable energy, particularly wind energy in maritime areas with low wind speeds (3–6 m/s). This study aims to design and test a vertical Savonius wind turbine system equipped with a Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm as a power source for shipboard water heating systems. The research method applied is Research and Development (R&D), integrating several components such as a DC generator, full-wave bridge rectifier, INA219 current sensor, anemometer cup sensor, ESP32 microcontroller, and a monitoring interface utilizing Google Spreadsheet and a 20x4 LCD. The system was tested under two operating conditions: without MPPT and with MPPT. The experimental results show that the application of the MPPT algorithm successfully increased power output by up to 272.64% while maintaining voltage stability despite varying wind speeds. Nevertheless, the average output power of 2.605 W remained insufficient to meet water heating requirements within a short time. For example, charging a 12V 50Ah battery would require approximately 9.6 consecutive days of operation, highlighting the system’s limitations in high-demand scenarios. Despite these constraints, the findings demonstrate that the vertical Savonius wind turbine integrated with MPPT has strong potential as a clean and environmentally friendly alternative energy solution for maritime applications, particularly for small-scale onboard electrical loads. This study contributes to renewable energy utilization in the shipping sector and provides a foundation for further technological development and optimization.
