This study aims to formulate an engineering strategy for water quality management and pollution control in the Tiku Sub-watershed, North Musi Rawas Regency. The study used a descriptive approach by integrating selected technical data from a dissertation-based assessment with semi-structured interviews involving 20 key informants representing technical agencies, village and subdistrict governments, community leaders, artisanal and small-scale gold mining actors, farmers, and riverbank communities. The analysis focused on water quality status, water availability and demand, pollution sources, perceived impacts, implementation constraints, and priority interventions. The results showed that the Tiku Sub-watershed is under significant environmental pressure. The average pollution index was 6.65, indicating a moderately polluted status, while mercury, cadmium, phosphate, and ammonia were the dominant parameters of concern. Surface water availability remained relatively adequate at 45,842,699.79 m3/year, and the average Criticality Ratio was 0.266; however, the water pollution carrying capacity was poor. Interview results indicated that mercury use and processing waste from artisanal gold mining were the most urgent issue (35%), followed by land-cover change and riparian degradation. The recommended strategy combines mercury-free processing technology, alternative livelihood development, cross-sectoral supervision, riparian rehabilitation, and transparent water-quality monitoring. The findings imply that watershed engineering should integrate technical, institutional, and socio-economic interventions.

Substandard housing remains a multidimensional urban problem because it intersects with structural safety, indoor environmental quality, sanitation, clean water, poverty, and the effectiveness of policy implementation. This study evaluates the implementation of the substandard housing improvement program (RTLH) in Lubuk Linggau City by integrating a technical audit of housing quality with an implementation analysis based on the variables of communication, resources, implementer disposition, and bureaucratic structure. A descriptive-evaluative mixed approach was applied through field observation, technical scoring of ten rehabilitated houses, document review, and structured interviews with regulators, field facilitators, and beneficiary households. The results show that the cumulative technical conformity index reached 3.325 out of 4.00, equivalent to 83%, and was classified as adequate housing. Structural resilience achieved the highest score at 88%, followed by space adequacy at 85%, natural lighting and ventilation at 80%, and sanitation and clean water at 75%. Five houses were classified as adequate housing, while five were classified as fairly adequate/light substandard housing. The implementation analysis indicates that clear practical communication and facilitator assistance strengthened structural quality, but limited financial resources, weak environmental-health prioritization, and administratively oriented supervision reduced sanitation and ventilation performance. The study recommends standardized septic systems, stronger post-construction technical verification, healthy-housing education, realistic unit budgets, and quality-oriented monitoring.

This study was conducted based on the crucial role of diesel generator engines as the primary source of electrical power on board ships, making their operational reliability essential. One of the factors influencing generator engine performance is lubricating oil temperature. Excessive lubricating oil temperature may reduce lubrication effectiveness, increase friction between moving components, and lower engine efficiency. Therefore, this research aimed to identify the causes of high lubricating oil temperature in diesel generator engines and determine appropriate corrective actions. The study employed a descriptive quantitative approach. Data were collected through direct observation, interviews, and documentation during sea practice aboard MV. CL FLANDERS from 4 July 2024 to 5 July 2025. The data were analyzed using simple linear regression to examine the relationship between generator load and lubricating oil temperature. The findings revealed that generator load had a significant effect on the increase in lubricating oil temperature. Under normal operating conditions, the lubricating oil temperature ranged from 60°C to 72°C, while under abnormal conditions it increased to between 68°C and 81°C. The abnormal rise in temperature was mainly caused by cooling system problems, particularly a dirty LO cooler, scale deposits on the sea water pump impeller, and blockage in the cooling capillary pipes. The regression equation under normal conditions was Y = 45 + 0.30X, whereas under abnormal conditions it was Y = 53.5 + 0.30X. Elevated lubricating oil temperature resulted in lower oil viscosity, higher fuel consumption, and reduced diesel generator engine performance. Therefore, regular maintenance of the LO cooler, sea water pump, and continuous temperature monitoring are necessary to maintain optimum engine performance.

Employee attendance is an important indicator to demonstrate the discipline and performance of village employees. The process of recording employee attendance previously at the Lumban Dolok Village Office was still done manually. This can cause problems such as incorrect data, slow report collection, and absenteeism. Therefore, the purpose of this study is to develop a web-based presence-monitoring information system that uses the Location-Based Service (LBS) method. The purpose of the LBS method is to ensure that the attendance process can be carried out only when employees are within a specified radius of the Lumban Dolok Village Office. This system uses latitude and longitude data from the user's device to calculate the geographic distance to the location's center point. The developed system uses the user's device's latitude and longitude to calculate the distance between the employee's location and the attendance center. Within a radius of 25 meters, the attendance process can only be carried out if the employee is within that radius; if they are outside the radius, then the attendance will be automatically rejected by the system. In this study, the waterfall system development method was employed, with PHP and UML. The results of the study show that this system can help the village office monitor employee attendance directly, speed up the collection of attendance reports, and reduce the risk of data manipulation. In addition, attendance reports are easily accessible by admins and village heads to assess employee performance. Thus, the web-based attendance information system using the LBS method is expected to improve compliance, transparency, and effectiveness of attendance management at the Lumban Dolok Village Office.
