Abstract

In general, the condition of drainage systems in various cities across Indonesia is facing a wide range of problems. An effective drainage system plays a crucial role in preventing floods and waterlogging, especially in densely populated urban areas such as Depok City. With the rapid pace of urbanization, the drainage infrastructure in Depok is confronted with multiple challenges, both technical and environmental in nature. This article examines the current state of the drainage system in Depok by utilizing reliable data and documenting real-life occurrences observed in the field. Through an in-depth analysis of rainfall data, the physical condition of drainage channels, and several flooding incidents that have occurred in recent years, this paper aims to provide a comprehensive overview of the situation. It also seeks to offer practical and strategic recommendations to improve drainage management in the area, thereby supporting better urban planning, disaster mitigation, and sustainable infrastructure development in the long term.

Abstract

The problem of household organic waste in Indonesia is increasing along with population growth and consumption patterns. Suboptimal waste management can lead to various negative impacts, such as environmental pollution, greenhouse gas emissions, and health problems. One potential solution is the use of Black Soldier Fly (BSF) maggots (Hermetia illucens) as a bioconversion agent in organic waste processing. This study aims to determine the effectiveness of maggots in processing household organic waste and to assess their role as an environmental engineering effort. The research method used was a descriptive quantitative approach through direct observation of the organic waste decomposition process using maggots for 13 days. The organic waste used consisted of various types of household vegetable and fruit waste with a total weight of 10,379 grams. The results showed that the processing process produced 1,245.5 grams of maggot biomass and 1,476 grams of wet compost. Data analysis indicated that approximately 12% of the organic waste was successfully converted into maggot biomass, 14.2% into compost, and the organic waste reduction rate reached 73.8%. These results demonstrate that maggots have a high capacity to reduce organic waste volume quickly and efficiently. In addition to providing environmental benefits by reducing waste generation and greenhouse gas emissions, maggot utilization also produces economically valuable products in the form of high-protein alternative feed and organic fertilizer. Therefore, maggot utilization can be an effective, environmentally friendly, and sustainable environmental engineering solution for managing household organic waste

Abstract

Solar energy technology is one of the most rapidly advancing renewable energy solutions aimed at meeting electricity demands in a sustainable manner. This technology converts sunlight into electrical energy through two primary approaches: the photovoltaic (PV) system, which utilizes solar panels to directly transform sunlight into electricity, and the Concentrated Solar Power (CSP) system, which uses mirrors or lenses to concentrate solar heat for electricity generation. The main advantage of solar energy lies in its environmentally friendly nature, as it does not produce carbon emissions or harmful greenhouse gases. Moreover, solar energy is derived from the sun—a renewable and abundant source that will not deplete. Economically, solar technology offers long-term cost efficiency; after the initial installation, operational costs are relatively low and can significantly reduce or eliminate electricity bills. The versatility of solar applications is another key benefit, as it can be used for various needs, ranging from household systems to large-scale industrial projects. With these advantages, solar energy stands as a strategic alternative in supporting the transition toward a cleaner, more sustainable energy system and environmentally friendly, especially within the environment of Mpu Tantular University in Jakarta.
