Abstract

AbstractThis study aims to (1) Analyze the relationship between surface runoff and soil organic carbon loss in the Deli River Basin. (2) Determine the amount of soil organic carbon loss in the Deli DAS for a year. Observation and measurement techniques conducted this research at the sample point, namely at the Deli Watershed outlet, namely by taking water samples per water level and documentation techniques to collect secondary data related to the study area. Data analysis techniques used include qualitative data analysis techniques and qualitative analysis which provides for analysis of laboratory data for water sample testing to see organic carbon content per water level, statistical data analysis to analyze the influence and relationship of surface flow with water level in the Flow Area Deli River and calculate the total soil organic carbon loss in the Deli River Basin, and descriptive data analysis to describe soil organic carbon loss in the Deli River Basin. The results showed (1) there was an influence between surface runoff and soil organic carbon loss with a positive linear relationship where an increase would follow any increase in surface runoff in soil organic carbon loss, (2) soil organic carbon loss in the Deli River Basin was 6.04 tons/ha/ year.Keywords: watershed, Soil Organic Carbon, High Water LevelAbstrakPenelitian ini bertujuan untuk (1) Menganalisis hubungan aliran permukaan dengan kehilangan karbon organik tanah di DAS Deli. (2) Mengetahui jumlah kehilangan karbon organik tanah di DAS Deli selama setahun. Penelitian ini dilakukan dengan teknik observasi dan pengukuran pada titik sampel yaitu di outlet Daerah Aliran Sungai Deli yaitu dengan mengambil sampel air per tinggi muka air dan teknik dokumentasi untuk mengumpulkan data sekunder yang berkaitan dengan daerah penelitian. Teknik analisis data yang digunakan antara lain teknik analisis data kualitatif dan analisis kuantitatif yang meliputi analisis data laboratorium untuk uji sampel air untuk melihat kadar karbon organik per tinggi muka air, analisis data statistik untuk menganalisis pengaruh dan hubungan aliran permukaan dengan tinggi muka air di Daerah Aliran Sungai Deli serta menghitung total kehilangan karbon organik tanah di Daerah Aliran Sungai Deli, dan analisis data deskriptif untuk mendeskripsikan kehilangan karbon organik tanah di Daerah Aliran Sungai Deli. Hasil penelitian menunjukkan (1) terdapat pengaruh antara aliran permukaan dengan kehilangan karbon organik tanah dengan hubungan linier positif dimana setiap terjadinya peningkatan aliran permukaan akan diikuti dengan peningkatan kehilangan karbon organik tanah, (2) kehilangan karbon organik tanah di Daerah Aliran Sungai Deli adalah sebesar 6,04 ton/ha/tahun.Kata Kunci: DAS, Karbon Organik Tanah, Tinggi Muka Air

Abstract

Climate change represents a critical and pressing global challenge that demands immediate attention. To effectively mitigate the impacts of climate change, it is essential to implement comprehensive educational programs that raise awareness, foster understanding, and equip individuals and communities with the knowledge and skills necessary to combat its effects. Climate change has been integrated into the curriculum in Indonesia across natural science and social science subjects. It is important to analyze the differences between these two subjects on climate change knowledge and perception. This study aims to compare students' knowledge and perceptions of climate change in natural science and social science students due to a gap in subject content. Furthermore, this study also examines the extent to which the level of knowledge affects students' perceptions of climate change. A questionnaire as a survey method about students’ knowledge and perceptions of climate change and its impacts was given to 150 students of natural science and social science students in MAN 2 Padang Sidempuan. The results indicated there is no statistically significant difference between natural and social students in terms of climate change knowledge and perceptions (sig. > 0.05). These findings imply that the distribution of climate change knowledge and perceptions is relatively uniform across disciplinary backgrounds.

Abstract

The European Union Deforestation Regulation (EUDR) is a challenge for all plantation producers. Jambi Province, which is famous for its palm oil and rubber products, finds itself with a new regulation that will bind the terms and conditions for its sales and purchases. This EUDR was originally effective on December 31, 2024. However, its application was delayed until December 31, 2025. The purpose of this study is to see the preparation of Jambi Province in welcoming the EUDR. Using a qualitative research method, open interviews. Interviews were conducted with the Head of the Agriculture Department, and PTPN IV regional 4 and head of the marketing team from the Ministry of Agriculture. The results of the interview showed that currently Jambi Province through the Sustainable Palm Oil Regional Action Plan (RAD KSB) program through BioCF funding and Palm Oil Profit Sharing Funds is trying to carry out ISPO certification for oil palm farmer groups in Jambi Province. However, in the process, this activity was deemed insufficient due to budget constraints which resulted in the certification target being only a few small groups in 2025. Head of the Marketing Working Team made a recommendation to involve third parties in acceleration efforts. So that the limited funds do not need to be used for tagging, enough for data verification with the village government. By adopting the recommended scheme, it is hoped that Jambi Province can be better prepared to face the end of 2025 when EUDR has begun to be implemented.

Abstract

Sampah merupakan permasalahan lingkungan yang paling krusial di Kabupaten Agam. Sebaran sampah organik terutama sampah kelapa yang merupakan salah satu komoditi unggulan di Kabupaten Agam belum tertangani dengan baik. Pengabdian ini bertujuan untuk mengolah sampah kelapa menjadi cocopeat yang bernilai ekonomi. Pengabdian ini melibatkan Dinas Lingkungan Hidup sebagai pengumpul dan pengangkut sampah kelapa dan BUMNag Lubuk Basung sebagai pengolah limbah kelapa menjadi cocopeat. Pengabdian dilakukan dengan metode ABCD (Asset Based Community Development) dan juga RSS (Responsible Sourching from Smallholders). Hasil kegiatan pengabdian meliputi proses persiapan, penilaian, perencanaan, pelaksanaan, pemantauan. Limbah sabut kelapa dapat diolah menjadi media tanam cocopeat yang dapat mendukung kegiatan pertanian masyarakat dan mengurangi sampah organic di Kabupaten Agam. Pengabdian ini merekomendasikan pengolahan limbah sabut kelapa mudah dengan proses lignikasi untuk mendapatkan cocopeat yang lebih ekonomis.

Abstract

Rapid urbanization and vegetation loss significantly intensify the Urban Heat Island (UHI) effect, escalating ecological vulnerability in tropical coastal cities. This study evaluates the spatial relationship between urban warming and environmental degradation in Padang City, Indonesia—a medium-sized tropical coastal city characterized by rapid development and a sharp topographic transition from coastal lowlands to eastern mountains. Utilizing Landsat 8 satellite imagery (January 2023–January 2024) processed via Google Earth Engine (GEE), this research integrates Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), and built-up indices to map UHI intensity and the Environmental Criticality Index (ECI). The results reveal a stark west-east environmental dichotomy: the highly built-up western coastal lowlands act as intensive urban heat hotspots, exhibiting low NDVI values (down to -0.35), maximum LST values of 33.47°C, and high environmental criticality (covering 6.92% of the total area). Conversely, the eastern mountainous zone naturally mitigates thermal stress due to high forest canopy cover and environmental lapse rate benefits. Statistical analysis confirms a strong positive correlation between ECI and LST (r=0.72), demonstrating that urban overheating directly drives broader environmental degradation. Although limited by a single-year dataset and a lack of in-situ validation, this study provides a novel framework for mapping ecological vulnerability. These findings underscore the urgent need for climate-resilient spatial planning in Padang, including mandatory building-scale blue-green infrastructure (green roofs and walls) in the dense western core and strict enforcement of a minimum 30% green open space (RTH) quota in expanding sub-urban zones.
