Low-rank coal generally has a high moisture content, which results in a low calorific value and suboptimal quality for utilization as an energy source. One method that can be applied to improve coal quality is the Upgrading Brown Coal (UBC) process, which functions to reduce moisture content and increase fixed carbon value. This study aims to analyze the effect of heating time and the ratio of used oil composition on improving coal quality based on proximate parameters. The research method includes collecting coal samples from four locations in Samarinda and its surrounding areas, namely SMAN 1 Samarinda, Bhineka Street, Palaran Stadium, and Tani Bakti Village. The samples were analyzed using proximate analysis, including inherent moisture (IM), ash content (AC), volatile matter (VM), and fixed carbon (FC), both before and after the UBC process. The upgrading process was carried out with variations in heating time and used oil composition as a coating medium to enhance coal stability and prevent moisture reabsorption. The final results of the upgrading process showed the best values of inherent moisture at 13.64%, ash content at 4.66%, volatile matter at 55.06%, and fixed carbon at 44.94%. The results indicate that the UBC process is capable of reducing inherent moisture and increasing fixed carbon, thereby improving coal quality. Variations in heating time and used oil composition have a significant effect on changes in proximate parameters. Longer heating time and an appropriate ratio of used oil composition result in a more optimal improvement in coal quality.

Slum upgrading is a strategic step in improving the quality of life of urban communities, where its success is largely determined by the active involvement of local residents. This study aims to analyze the level of community involvement in the implementation of slum upgrading in Mantuil Village, South Banjarmasin District. Using a descriptive quantitative approach, data were collected through a structured questionnaire from 98 respondents selected using a purposive sampling technique. Data analysis was conducted descriptively to measure the level of participation in four stages of the activity. The results show that community involvement is in the good category, but has an uneven distribution. The highest average scores were found in the utilization stage (30.44) and maintenance stages (30.23), indicating that community participation is driven by the principle of direct benefit from the infrastructure being built. Conversely, participation in the planning and implementation stages tends to be lower due to structural barriers such as time constraints and respondents' economic burdens. These findings confirm that sustainable settlement upgrading requires synergy between community social capital and government policies that are adaptive to the geographic characteristics of the region, particularly related to tidal flooding vulnerability in riverbank areas.
