Abstract

One of the impacts of the growth of activities in the transportation sector is the disposal of rubber tire waste. The increasing number of motorized vehicles in society has caused an increase in tire waste. Especially in developing countries, the use of plastic bottles has become an inevitable and unavoidable necessity for society. Inadequate waste management and handling causes negative impacts on the environment, such as hazards to human health, to animal life, soil, water, and air pollution. The purpose of this study was to reduce environmental pollution by testing the compressive strength of concrete made with a mixture of waste. Experiments were conducted in the laboratory with concrete cylinder test objects with a diameter of 150 mm and a height of 300 mm. The proportion of waste mixture, Polyethylene Terephthalate (PET), Rubber Powder, Waste Metalized Film Food Packaging (WMFFP) to fine aggregate was 0%, 5%, and 10%, each variation. The test results showed a compressive strength of 17.62 MPa, 15.29 MPa, and 14.83 MPa at the percentage of waste mixture. From this data, it can be concluded that waste materials can be used as a substitute for sand in concrete.

Abstract

The construction industry is one of the fields where the implementation of Occupational Safety and Health (K3) is still not optimal, as evidenced by the still high number of work accidents. Efforts to increase this awareness can be done early on through education and training, one of which is through Vocational High Schools (SMK). In general, students are still not aware of the possibility of work accidents. Providing K3 training from an early age can help students develop the knowledge, attitudes, and behaviors that will be needed in the workplace later. The purpose of this program is to provide knowledge and skills to students of SMKN 1 Kemlagi, Mojokerto Regency regarding the basics of construction K3. The methods used to educate students through K3 learning include lectures and socialization, as well as evaluation through pre- and post-tests. Overall, K3 education activities are able to improve the understanding of students in the Building Design Modeling and Information Department of all topics discussed, including risk control strategies, preventing and dealing with fires in the work area, recognizing personal protective equipment.

Abstract

Urban waste generation continues to rise in line with increased consumption patterns, particularly in rapidly developing cities. This study analyzes the effectiveness of community-based waste banks in reducing municipal waste volume, lowering methane emissions, and strengthening urban climate resilience. Waste banks play a pivotal role in diverting recyclable and organic materials from landfills through structured sorting systems, economic incentives, and integrated organic processing such as composting and maggot cultivation. These mechanisms significantly reduce anaerobic decomposition, which is the primary source of methane emissions in landfills. Community participation, institutional capacity, technological support, and government collaboration emerge as key factors that determine the overall performance of waste bank programs. The development of circular economy practices within waste bank operations contributes to environmental quality improvement while simultaneously generating economic benefits for local communities. The findings highlight that waste banks are not only tools for waste reduction but also essential components of urban climate mitigation strategies. Their ability to integrate social, ecological, and economic functions positions them as effective, low-cost solutions for modern urban environmental management.
