Abstract

This research focuses on understanding the characteristics of the Urban Heat Island (UHI) phenomenon in Parepare City, Indonesia, and its relationship with vegetation density and land surface temperature. The study utilizes satellite imagery data from 2014 and 2021 to analyze the spatial distribution of land surface temperature and vegetation density. The results show a significant negative correlation between vegetation density and land surface temperature, indicating that an increase in vegetation density can contribute to lowering the land surface temperature and mitigating the UHI effect. The findings also emphasize the importance of green open spaces in maintaining a balance of vegetation and preventing a drastic increase in UHI. However, challenges such as land conversion and high population density in the city center pose threats to vegetation preservation. Sustainable land management practices and urban greening initiatives need to be implemented to address these issues. The research concludes that by prioritizing these measures, Parepare City can effectively mitigate the UHI effect and enhance the urban environment's quality and livability.

Abstract

This research aims to determine the flood intensity in Makassar City, which is influenced by several factors, including land use, slope gradient, land cover, and rainfall. The research method is a quantitative approach using spatial analysis to examine spatial phenomena. The spatial analysis was conducted using an overlay method with a scoring technique to map each variable that affects flood intensity. The analysis results indicate that the flood intensity in Makassar City is categorized into three levels: low, moderate, and high.. The analysis results suggest that in Makassar City, 37.4 km² or 21% of the total area falls into the low rainfall intensity category. In contrast, the moderate rainfall intensity category encompasses 73.3 km² or 41% of the city, while the high rainfall intensity category represents 68.1 km² or 38% of the total area. This research has implications for efforts to control the pace of regional development that influences and potentially exacerbates flooding, thereby enabling early mitigation of environmental issues.

Abstract

The implementation of long segment-based contracts which is considered new for service users and large contractors, the implementation of roads. So it is necessary to understand the system. The parties have difficulty implementing the standards that have been determined and understanding the scope of the work being carried out, resulting in the implementation of long segment-based work not being carried out effectively until now. Seeing the above problems, this research was carried out to The method used in this study uses the Importance perpormance analysis (IPA) questionnaire method. In accordance with the limitations of this study, the number of respondents used was 30 service users and 30 service providers at the Southeast Sulawesi Road Implementation CenterThe method used in this study used the Importance perpormance analysis (IPA) questionnaire method. In accordance with the limitations of this study, the number of respondents used was 30 service users and 30 providers Factors of understanding from Officials Commitment Makers (PPK) as service users place understanding in contract law as the dominant factor with weight (0.195), while service providers/contractors place the ability to understand contract law as the dominant factor with weight (0.206).
