Abstract

Deli watersheds are listed as one of the most heavily damaged watersheds in Indonesia, and this causes many problems, such as floods, flash floods, and landslides. Studying this watershed becomes essential because the Deli watershed passes through a major city and has become the main source of flood and other natural disasters in the city such as Medan, The study aims to detect the vulnerability level of the areas around the watershed and the most rapid and possible way to study it is by using remote sensing and GIS, the overlay method by considering several parameters that affect the level of vulnerability to flooding in Deli Watershed, North Sumatra. Some of the parameters considered include the topographic wetness index, slope, land elevation, river flow density, land use cover, normalized difference vegetation index, distance to river, and rainfall. Each parameter is given a weight and value according to each classifier. The overlay process is carried out using ArcGIS 10.8.1 software, results are divided into 5 levels of area vulnerabilities all around the area, the study shows that all parts of Medan City in the Deli watershed have a high level of flood vulnerability and some areas with higher ground elevation such as Tanah Karo have spots area that is vulnerable with floods such as Daulu District with 0.45 ha and Semangat Gunung District with 0.63 ha of its areas are vulnerable to floods. The Topographic wetness index, Normalized difference vegetation Index, slope, and land use are the main factors causing flooding with weighting values 16, 13, 11, and 14. The other parameters elevation, flow density, distance to the river, rainfall, and soil class each have weighting values 7, 10, 11, 8, and 10. Slope with a range of 0-8% in most areas of Medan City are classified as very prone to flood inundation. This is due to the area's flat topography and low river flow density, the existing 3.5 km old sewer in the Deli Tua area is unable to accommodate the flood inundation load in the city of Medan and it is necessary to build two new sewers which are more effective and efficient in diverting the flow of water, before entering the city of Medan which makes the area vulnerable to becoming a water catchment area when it rains, thereby increasing the risk of flooding. With this flood-prone map, efforts to manage and mitigate floods in Medan City can be carried out. Information on vulnerable locations can be used to take appropriate preventive and countermeasures, such as building adequate drainage, regulating land use, and controlling river flows.

Abstract

Medan City, the third-largest city in Indonesia, faces significant challenges in managing its public green open spaces (RTH) due to high population density, rapid urbanization, and insufficient green space, which falls far short of the 30% mandated by law. This research assesses the management of public green spaces in Medan through a SWOT analysis, revealing internal strengths such as a Regional Spatial Plan and government commitment, alongside weaknesses like suboptimal management, lack of coordination between agencies, and inadequate regulations. External factors, including opportunities from NGO funding and potential land acquisition, contrast with threats like rapid population growth and misuse of green spaces. Through data collection methods, including focus group discussions, questionnaires, and interviews with key stakeholders, the research identified key areas for improvement in green space management. Strategic recommendations include strengthening policies, increasing public awareness, optimizing cross-sector collaboration, and promoting sustainable urban planning. Additionally, leveraging green spaces for economic growth through multifunctional uses can enhance their value to the community. This study concludes that public green open spaces in Medan City can contribute significantly to sustainable urban development and environmental balance if managed more effectively, with better coordination, stronger regulations, and resource allocation. The findings aim to provide valuable insights for urban planners and policy makers in achieving urban sustainability goals.

Abstract

Referring to Ministerial Regulation of PAN-RB No. 16 of 2009 on Teacher Functional Status and Credit Score, it is clearly mentioned that one of the key components to apply teacher promotion is scientific writing (KTI). However, in fact, it was found that many teachers were independently constrained, especially in Sibolga City. As a result, the chance to get a higher rank and to be placed would be hampered. In addition, even some teachers are caught up in taking shortcuts by using the third part services to prepare their scientific writing, which of course, are not acceptable in publication ethics and academic values. In line with the results of preliminary observations made by the team, it was noticed that the teachers writing ability can be improved by providing them writing coaching class, including explanations and even training materials that need to be used in scientific writing. This writing coaching class is intended to provide teachers an opportunity to develop their skills, especially skill to write down scientific papers. Writing coaching class will be done by encouraging teachers to compose their ideas, formulating their problems, obtaining references sources, providing consultation rooms, implementing ethics and scientific publishing regulation, and selecting places where scientific papers will be published.

Abstract

Gunung Leuser National Park (GLNP) is one of Indonesia's most important conservation areas. Around GLNP, there are a group manages bamboo forests in Pamah Simelir Hamlet. This activity aims to carry out outreach activities to increase the institutional capacity of sustainable bamboo communities to support the management of GLNP buffer areas in mitigating climate change. The activity methods include lecture methods, group discussions, brainstorming, role-playing, collective problem-solving, questionnaires and interviews with groups, and Focus Group Discussions (FGD). The results of the training activities showed that the group's technical skills had improved, especially in managing bamboo forests as part of conservation and climate change mitigation efforts. They can apply the techniques taught, such as planting and maintaining bamboo in a sustainable manner, as well as using bamboo as a raw material with economic value. Increasing these skills can reduce pressure on forest areas and improve the welfare of local communities. The training carried out has succeeded in positively boosting the institutional capacity of the Bambu Lestari Community, both in technical, managerial, and collaboration aspects. This activity can become a reference for local governments and stakeholders in adopting an inclusive and sustainability-oriented approach while involving local communities as partners in preserving the environment and facing the challenges of climate change.

Abstract

The Tapanuli orangutan (Pongo tapanuliensis), currently classified as critically endangered, inhabits the Batang Toru Ecosystem and persists in two wild populations. This study aims to analyze habitat suitability for the Tapanuli orangutan, the Importance Value Index (IVI), the Shannon Diversity Index (H′), and the Margalef Species Richness Index (Dmg) of tree species. Model accuracy, assessed by the Area Under the Curve (AUC) of a random test based on 25% of samples, was 0.993, while the overall predictive AUC reached 0.996, both classified as “excellent.” Elevation, precipitation, and distance from forest cover emerged as the most influential environmental variables. Habitat suitability classification revealed 60.23% as “unsuitable,” 28.77% as “suitable,” and 11.00% as “highly suitable.” In secondary forest, the highest IVI values were observed for hoteng (Lithocarpus hystrix) at 28.68%, mayang (Palaquium gutta) at 22.55%, and hayu horsik (Ilex pleiobrachiata) at 17.81%. In mixed gardens/agroforestry systems, durian (Durio zibethinus) had an IVI of 21.44%, mayang (Palaquium gutta) 18.82%, and medang (Persea declinata) 18.48%. Shannon diversity (H′) was high in both secondary forest (3.19) and mixed gardens/agroforestry (3.23), while stem density diversity was moderate in secondary forest (2.71) and mixed gardens/agroforestry (2.53). Margalef richness (Dmg) was high in both secondary forest (5.63) and mixed gardens/agroforestry (5.96), whereas stem richness was high in secondary forest (4.51) but moderate in mixed gardens/agroforestry (3.79).

Abstract

Sampah organik dan sampah plastik dapat menimbulkan masalah bagi lingkungan, karena membuat lingkungan menjadi kotor dan bau.  Untuk mengatasi masalah ini maka sampah organik dan sampah plastik tersebut diolah menjadi produk lain. Kegiatan ini dilakukan oleh Kelompok Tani Pondok Miri pada bulan Mei 2022. Tujuan kegiatan ini adalah untuk mengimplementasikan praktik daur ulang sampah plastik dan memanfaatkan sampah rumah tangga sebagai medium tanam dan pupuk untuk tanaman obat guna meningkatkan nilai jual dan pendapatan di antara masyarakat, yang diilustrasikan melalui studi kasus di kelompok tani Pondok Miri Asri, Desa Sei Semayang, Sunggal, Deli Serdang. Daur ulang sampah plastik dilakukan dengan menggunakan pipa paralon, botol bekas yang multifungsi untuk menanam tanaman obat, serta galon/gelas air mineral untuk menanam tanaman obat. Pengumpulan sampah plastik, seperti botol plastik, bungkus makanan, bekas pembungkus minyak, bekas gelas plastik, dan sejenisnya, dilakukan di Desa Sei Semayang, Kecamatan Sunggal, Kabupaten Deli Serdang untuk dijadikan wadah tanam bagi tanaman obat.
