Abstract

Urban heat island is one of the events where the temperature in the metropolitan area is warmer than the surrounding area. Indonesia is located in a tropical climate making several cities potentially increase in temperature during the dry season. As a representative, the City of Pekanbaru is one of the cities with infrastructure growth that is fast including on the island of Sumatra. Population growth and high enthusiastic of residents to find work in the city made land on the edge of the city built up. This makes the green space less and less with the uneven distribution of green space in the city of Pekanbaru. The number of buildings that exist makes the temperature rise in urban areas with an initial temperature of 29oC to 36oC. temperature increases occurred throughout the year with the hottest peaks of temperatures reaching 37oC on April 15, 2013. Whereas in 2009 there was a decrease in temperature with levels ranging from 27oC. This makes the city of Pekanbaru one of the hottest cities in Indonesia. This study uses Landsat 5 imagery for 2000 and 2009, and Landsat 8 for 2018 with the Land Surface Temperature (LST) method and Normalized Difference Built-up Index (NDBI) which are useful to explain the urban heat island distribution (UHI) in Pekanbaru City

Abstract

The aim of this study was to find out the spread of dengue hemorrhagic fever in the city of Palembang and then to create a policy direction for the prevention of dengue hemorrhagic fever in the city of Palembang. This study was undertaken in all areas of Palembang City. This sudy was descriptive with a quantitative approach. The sample of this study was dengue hemorrhagic fever patients who were found in each health center and community registered at the Palembang City Health Office using purposive sampling technique. Data collection consisted of observation data, the health office, interviews, documentation. Data analysis techniques used consisting geographic information system analysis and Analytical Hierarchy Process. The results indicated that the distribution of dengue hemorrhagic fever was of three levels, namely, high, medium, and low spread in 18 sub-districts in the city of Palembang. Furthermore, the policy directions given were: suppressing the rate of population growth, socializing about dengue hemorrhagic fever, improving drainage channels, eradicating mosquito nests, routine larvae inspection. on providing policy directions for dengue outbreaks starting from a basic understanding of the habitat structure of the aedes aegypti mosquito which will provide information related to the influence of the mosquito landscape in knowing the zoning of vulnerability to dengue outbreak transmission

Abstract

Over the past few years, numerous urban areas have been identified in floodplains and coastal regions. These areas should be repurposed as water storage zones to enhance surface water infiltration. The escalating demand for land in flat areas adds complexity to the susceptibility of urban areas to flood hazards. The observation focuses on understanding how land use change influences urban flood susceptibility assessment. Several aspects assumed to have a significant relationship with the flood phenomenon include the impact of land use change, environmental health impact, modification of land typology, explanation of urban flooding, appropriate model for flood-prone assessment, current state of research, appropriate steps in decision-making in susceptibility areas, and challenges of the scenario-based flood-prone mapping model in the future. Additionally, the assessment aspect should consider the impact of land degradation resulting from land use change. Integrated measures are necessary to guide future studies aimed at improving ecological quality and restoring environmental health. The availability of free and open-source datasets facilitates conducting studies to support decision-making both locally and regionally.

Abstract

Jasa ekosistem pengaturan air di Daerah Aliran Sungai (DAS) Cisangkuy bagian tengah dan hulu mempunyai peran penting untuk kehidupan manusia dan makhluk hidup lain di wilayah bawahnya. Hal ini terkait dengan kebutuhan air sehari-hari ataupun terkait dengan ancaman bencana, dikarenakan kerusakan ekosistem di wilayah atas dapat mendatangkan bencana banjir seperti yang selama ini terjadi di daerah penelitian. Penelitian ini bertujuan memantau jasa ekosistem pengatur air berdasarkan karakteristik biofisik wilayah. Pendekatan yang digunakan berbasis Multi Criteria Evaluation (MCE) terhadap tiga parameter utama yaitu Topographic Wetness Index (TWI), Normalized Difference Vegetation Index (NDVI), dan kemiringan lereng. Data utama yang digunakan adalah DEM SRTM 30m dan citra satelit Landsat 5 TM dan 8/9 OLI-TIRS periode 2000–2024. Hasil kajian menunjukkan bahwa nilai TWI daerah penelitian secara keluasan didominasi oleh kelas “tinggi” (40,72 %) dan “sangat tinggi” (36,79 %). Adapun untuk kelas lereng didominasi oleh kelas “agak curam” (23,09%) dan “curam” (23,07%). Sementara itu untuk kerapatan vegetasi (NDVI) terjadi perubahan luasan yang cukup dinamis. Kelas “sangat rapat” mengalami penambahan luas cukup signifikan dari 0,43 % (2000) menjadi 1,19 % (2004), dan meningkat tajam menjadi 45,26 % (2024). Sementara itu pada kelas “rapat” sempat naik dari 30,53 % (2000) menjadi 38,58 % (2004), namun mengalami penurunan menjadi 26,16 % (2024). Untuk kelas kerapatan “sedang” sempat naik dari 45,05 % (2000) menjadi 47,43 % (2004) namun turun menjadi 18,47% (2024). Dinamika perubahan luas ini berdampak pada nilai jasa ekosistem pengatur air dimana kelas “tinggi” sempat turun dari 37,95% (2000) menjadi 17,23 % (2004), namun meningkat kembali menjadi 37,76 % (2024). Temuan ini menegaskan bahwa telah terjadi perbaikan ekosistem DAS Cisangkuy bagian tengah dan hulu dalam kurun waktu 20 tahun (2004 ke 2024). Diharapkan kondisi ekosistem tetap terjaga atau membaik sehingga dapat menekan dampak banjir wilayah hilir di masa mendatang.
