Abstract

Awareness of Occupational Safety and Health (K3) is a crucial aspect in the vocational education environment, especially in vocational high schools that have a high intensity of workshop practice. SMK Negeri 1 Pantai Labu is one of the educational institutions in Deli Serdang that prepares students to enter the industrial world. However, initial observations show that students still have a low understanding of the risk of work accidents and the use of standard Personal Protective Equipment (PPE). This service activity aims to increase the knowledge and awareness of students and educators about the importance of K3 culture. The methods used are socialization through material presentations, demonstrations of the use of PPE, and simulations of handling emergencies. The results of this activity showed an increase in participants' understanding by 85% based on post-test evaluation.

Abstract

Agriculture in the arid regions of South Africa faces major challenges related to water scarcity, which worsens the sustainability of the sector. Water-efficient irrigation technology has emerged as a potential solution to reduce water use and increase agricultural productivity. This study aims to evaluate the impact of water-saving irrigation technology on water use efficiency and crop yields in arid regions of South Africa. Quantitative and qualitative approaches were used in this study, involving 150 farmers as a sample, as well as questionnaire data analysis and in-depth interviews. The results of the study show that this technology is able to increase water use efficiency by up to 30%, increase crop yields by 20%, and reduce average operating costs by 15%. The conclusion of the study is that water-efficient irrigation technology plays an important role in improving the sustainability of agriculture in dry regions and can contribute to food security in South Africa. The adoption of this technology needs to be encouraged more widely through government support and training for farmers.

Abstract

This study aims to map flood hazard areas in the Babura Sub-Watershed, Medan City, using the Geomorphic Flood Index (GFI) approach based on topographic data. The method was selected as an alternative under conditions of limited hydrological and hydraulic data by utilizing a Digital Elevation Model (DEM) and derived analyses, including flow direction and flow accumulation. The analytical process involved DEM preprocessing, geomorphological parameter calculation, and spatial classification of flood hazard levels. The results show that the GFI method successfully identified several high flood susceptibility zones, particularly around Jalan Kapiten Purba, Jalan Pintu Air IV, Kwala Bekala, J-City Housing, and parts of the Citra Wisata residential area, which correspond well with actual flood events recorded during the Medan flood in November 2025. However, discrepancies were also observed in certain downstream areas, such as the Soewondo Air Base, where the model indicated high susceptibility despite limited actual flood occurrence. These differences highlight limitations of the geomorphological approach, particularly its inability to account for hydraulic processes, infrastructure conditions, and land-use influences in detail. Despite these limitations, the GFI method proved to be a rapid and cost-efficient tool for generating preliminary flood hazard maps, making it a reliable initial approach for understanding potential flood inundation patterns and supporting flood mitigation planning and risk management.
