This community service program was conducted in Giriklopomulyo Village, Sekampung District, East Lampung, through a participatory training approach and hands-on practice involving community leaders and two invited experts. Students were also engaged in the waste processing sessions and the preparation of procedural texts based on field experiences. The evaluation results indicated significant improvements in participants’ knowledge, technical skills, ecological awareness, and functional literacy. In addition, participants’ vocabulary mastery related to environmental and agricultural terms increased by 35% as shown in the pre-test and post-test results. The hands-on method proved effective in encouraging active involvement of both the community and students in addressing waste management issues. This program demonstrates that collaboration between universities and rural communities can create locally based, applicable solutions. These findings are essential as a foundation for developing similar programs in other regions with high organic waste potential.</span> </p> Ema Puspitasari Hamatun Riski Rusmalinda Lukman Habibul Umam Yusuf Mustofa Khabibul Khoiri Hak Cipta (c) 2025 SEWAGATI: Jurnal Pengabdian kepada Masyarakat 2025-08-19 2025-08-19 4 2 1 9 10.61461/sjpm.v4i2.129 https://www.ejurnal.sarauinstitute.org/index.php/sewagati/article/view/131 <p><span class="fontstyle0">The Urban Heat Island (UHI) phenomenon in Surabaya is becoming increasingly apparent due to the conversion of green areas into built-up areas. This community service activity aims to map land surface temperature (LST) for the period 2016–2024 using Landsat 8 level 2 imagery and present it in augmented reality (AR) visualization to support public literacy. The analysis was conducted through calculations of NDVI, emissivity, LST, NDVI–LST linear regression, and field validation using<br />a thermohydrometer. The results show that the distribution of LST increased in 2016–2019, decreased in 2020, then increased again in 2021–2023 before decreasing in 2024. The negative correlation between NDVI and LST indicates that vegetation plays an important role in reducing temperatures. Field validation produced a coefficient of determination (R²) of 0.7213 with a maximum difference of 5°C between satellite data and measurements. The 2024 UHI map shows high intensity in densely built-up areas (Tegalsari, Genteng, Sawahan, Tambaksari, Wonokromo, and parts of Rungkut), while outlying areas like Benowo and Pakal are relatively cooler. AR-based visualizations have proven effective in helping the public and policymakers understand the UHI phenomenon more interactively and encouraging the development of mitigation strategies through reforestation and sustainable urban planning.</span> </p> Muhammad Hanif Noorlaila Hayati Filsa Bioresita Husnul Hidayat Megivareza Putri Hanansyah Lalu Muhamad Jaelani Bangun Muljo Sukojo Ferdian Zaki Rahmansyah Hak Cipta (c) 2025 SEWAGATI: Jurnal Pengabdian kepada Masyarakat 2025-09-18 2025-09-18 4 2 10.61461/sjpm.v4i2.131
