Permasalahan yang dialami DAS Binanga Lumbua dari hasil observasi singkat sebelumnya mengindikasikan bahwa DAS ini mengalami kekritisan. Hal tersebut terindikasi karena pada saat musim hujan, wilayah ini mengalami banjir akibat luapan dari DAS. Ketika musim kemarau, wilayah ini mengalami kekeringan dan benar-benar tandus. Salah satu hal yang dapat dilakukan dari adanya indikasi kekritisan pada DAS ini adalah dengan tetap menjaga keseimbangan ekosistem di DAS melalui upaya Pengelolaan DAS menggunakan teknologi spasial Sistem Informasi Geografis (SIG). Tujuan penelitian ini diarahkan untuk mengalisis tingkat kekritisan ekosistem lingkungan DAS Binanga Lumbua dan memberikan arahan pemanfaatan ruang untuk mengelolah lingkungan di DAS Binanga Lumbua berdasarkan pada zonasi tingkat kekritisan. Metode analisis yang digunakan adalah teknik analisis overlay dengan mengunakan teknologi spasial GIS. Kekritisan DAS dapat dilihat melalui pendekatan keberadaan air tanah yang berdasarkan pada parameter hidrogeomorfologi dan analisis ini menghasilkan peta tingkat kekritisan DAS. Dari peta tingkat kekritisan DAS inilah yang dijadikan dasar dalam menentukan langkah pengelolaan apa yang akan dilakukan di area DAS Binanga Lumbua ini. Diharapkan pula, penelitian ini bisa dijadikan sebagai langkah awal wilayah ini dalam mengatasi permasalahan lingkungan pada daerah aliran sungai setempat.

Kritisnya DAS Binanga Lumbua berkontribusi pada penurunan pendapatan perkapita Kabupaten Jeneponto. Ini juga menjadi salah satu alasan mengapa Kabupaten Jeneponto menjadi satu-satunya wilayah di Provinsi Sulawesi Selatan yang termasuk dalam kategori daerah tertinggal.Jika melihat kondisi fisik wilayah ini yang mempunyai topografi variatif dan tanah yang subur,semestinya wilayah ini memiliki nilai ekonomi yang potensial untuk pengembanganhutan,tanaman perkebunan,maupun pertanian tanaman pangan. Hasil penelitian sebelumnya adalah identifikasi kekeringan dengan menggunakan pendekatan hidrologis secara kualitatif dan kuantitatif.Kemudian, memberikan arahan pemanfaatan ruang yang berbasis pada upaya pencegahan bencana kekeringan. Sehingga dalam penelitian lanjutan ini, tujuan yang akan dicapai adalah merancang konsep one river one plan dalam penataan DAS Binanga Lumbua secara komperehensif untuk mewujudkan pembangunan yang berkelanjutan. Analisis yang digunakan adalah berupa analisis spasial dan deskriptif kualitatif.Hasil penelitian ini berupa pemetaan konsep penataan DAS yang berbentuk site plan. The criticality of the Binanga Lumbua watershed is that it contributes to the decline in the income per capita of Jeneponto Regency. This is also one of the reasons why Jeneponto Regency is the only area in South Sulawesi Province that is included in the category of underdeveloped areas. Looking at the physical condition of this area which has a varied topography and fertile soil, this area should have potential economic value for the development of forestry, plantation crops, and food crop agriculture. The results of previous research were the identification of drought using a hydrological approach both qualitatively and quantitatively. Then, provide directions for spatial use based on drought prevention efforts. So that in this follow-up research, the goal to be achieved is to design a 'one river one plan concept' in the comprehensive arrangement of the Binanga Lumbua watershed to realize sustainable development. The analysis used is in the form of qualitative descriptive and spatial analysis. The result of this research is a mapping of the watershed planning concept in the form of a site plan

One of the major cities in Indonesia that is currently experiencing a significant population increase is Makassar City. The increase in population in Makassar City is always followed by the increase in residential and non-settlement buildings. This can be seen in the development of the Tanjung Merdeka Sub District which is increasingly experiencing an increase in development activities. In addition, land prices in the area have also skyrocketed and caused massive, uncontrolled land conversion, and also affected the welfare order of local communities in the region. The objectives of the study are; (1) to analyze the land use changes in the Tanjung Bunga Metro Area; (2) to analyze the socio-economic changes of local community communities in the Tanjung Bunga Metro Area; (3) Analyze the implications to the extent of changes in the use of space on socioeconomic changes in local community communities. The analysis methods used are spatial analysis techniques, qualitative statistics, and quantitative descriptive. The results of this study are in the form of recommendations for the direction of space utilization in realizing welfare in local communities in the Metro Tanjung Bunga Area.

Flood is a disaster that often occurs in big cities in Indonesia, caused by the high density of buildings and the unpreparedness of infrastructure to adapt. Urban Areas of Bulukumba Regency (UABR) is one of the centers of urban areas that has experienced flooding in recent years. The urban area ofBulukumba Regency is a downstream area of the Bialo Watershed whose upstream area is also in the Bantaeng Regency area. Rapid urban development has resulted in a change in land cover to become built-up land so that catchment areas are narrower in the middle and downstream zones, as well as changes in vegetation in the upstream zone which has received land conversion from forest areas to plantation areas. In addition to the potential for flooding due to river flow, the urban area of Bulukumba also has the potential for flooding due to sea tides or tidal floods. The high level of hazard flood potential has not been followed up with sustainable flood management based on disaster risk reduction in the UABR. Based on this, it is necessary to study the level of risk of flooding in the Urban Area of Bulukumba Regency and an appropriate strategy to reduce the risk of flooding in the Urban Area ofBulukumba. The aim of this research is; (1) identify the level of risk of flooding in the UABR; and (2) formulate an appropriate strategy as an effort to reduce the risk of flood disaster in the UABR. The research approach used is the mixed method, with the analytical method used for data processing in the form of risk analysis, spatial analysis namely overlay analysis using GIS software and qualitative descriptive in formulating strategies. The results of this study are a map of the level of flood disaster risk and recommendations for flood risk reduction strategies in the UABR.

Watershed (DAS) can simply be interpreted as one of the containers that has the function of flowing rainwater into the lake or sea. Land use change in the upper reaches of the Bialo watershed which causes cultivation are one of the causes of flooding in the downstream area of the Bialo watershed. The purpose of this study is to analyze the level of hazard, vulnerability, capacity, and risk of flooding in the Bialo River Basin. The data collection method in this study used interviews, documentation, observation, and literature studies. The analytical methods used in this study are quantitative descriptive methods, spatial analysis, and qualitative descriptive. Quantitative descriptive methods are used to analyze hazard, vulnerability, capacity and risk. Spatial analysis that used in the process of modeling the results of calculating the hazard, vulnerability, capacity, and risks. Qualitative descriptive methods are used to interpret the results of spatial analysis. The results of this study is shows that the level of flood risk in the Bialo watershed consisted of 3 classifications, namely low, medium and high. Low Area 3342.39 Ha, Medium 6748.27 Ha and High 807.86 Ha.

Climate change and global warming have caused widespread environmental degradation. These impacts are directly experienced in Indonesia, particularly in the urban area of Bulukumba Regency, specifically in Ujung Bulu District. The increase in land use changes toward built-up areas has influenced the intensity of the Urban Heat Island (UHI) phenomenon. This study aims to analyze the effect of land use change on the Urban Heat Island (UHI) phenomenon in Bulukumba Regency during the periods of 2014, 2019, and 2024. A quantitative method was employed through satellite image interpretation to identify land use changes and analyze surface temperature using Landsat 8 Band 10 imagery data. The results indicate an increase in surface temperature in the urban area of Bulukumba Regency throughout the 2014–2024 period. The simple linear regression analysis shows a significant positive correlation between land use change and surface temperature increase, with a regression coefficient (r = 0.734) and a coefficient of determination (R² = 0.81), which falls into the high category. Furthermore, areas with high surface temperatures tend to follow the spatial pattern of densely built-up land use.
