Abstract

The increasing human activities and climate change have significantly contributed to global warming, which threatens environmental sustainability. The construction sector is one of the major contributors to environmental degradation and climate change due to its high carbon emissions. As a solution, the implementation of the green building concept has been developed. This concept emphasizes the use of renewable energy and the application of zero-energy-use principles. This condition creates opportunities for students of SMA Institut Indonesia Semarang to produce scientific articles and academic writings related to green building. This activity aims to improve students’ abilities in writing scientific articles on green building themes that align with environmental and sustainability issues. The methods applied include lectures, discussions, and simulations. The pre-test and post-test results indicate an increase in participants’ understanding from 43.75% to 81.25% regarding green building concepts and scientific writing. This improvement serves as an indicator of the program’s success. The activity received positive responses and full support from the school, and it had a beneficial impact on enhancing students’ fundamental understanding of scientific writing, particularly in the green building topics that are highly relevant to current environmental issues.

Abstract

During the rainy season or under heavy rainfall events, roads in Purwodinatan Subdistrict, Semarang City, frequently experience water ponding. This condition disrupts community activities and other road users. Insufficient drainage capacity to accommodate rainfall volume, along with inadequate drainage maintenance that leads to sedimentation, contributes to surface runoff and water inundation. These conditions require further mitigation measures to control surface runoff and shorten the drainage recession time. Therefore, the planning of infiltration wells is proposed as an alternative solution to address this problem. The implementation method adopted in this study consists of a literature review related to the design dimensions of infiltration wells, followed by the calculation of the Bill of Quantities (BoQ). The planning conducted represents a preliminary approach and is solely based on a literature review of infiltration well design, without involving detailed technical analyses of infiltration well capacity. Based on the BoQ calculation, a cost of IDR 6,462,954.92 is required to construct one infiltration well along the Bubakan Baru Street segment, where 9 infiltrations well locations are identified within a single road segment. The final outputs of this activity include a map of proposed infiltration well locations and the BoQ calculation to be submitted to the subdistrict authority. This activity serves as a preliminary planning stage to assist the community in estimating the dimensions, number of locations, and cost of infiltration wells.

Abstract

The primary issue in Demakan Village, Banyubiru, Semarang Regency, is the high volume of rainwater runoff that frequently causes puddles in public areas. This community service aims to implement Horizontal Infiltration Pipe (HIP) technology as an eco-friendly drainage solution. The implementation method consisted of coordination and socialization with village officials and residents, site surveys, system design, and installation of a perforated horizontal infiltration pipe network at the Demakan Village Office on 15 November 2025. The implementation resulted in the successful establishment of a functional HIP system that reduced localized ponding around the office area, facilitated rainwater infiltration into the surrounding soil, and served as a practical demonstration of sustainable drainage technology for the community. The activity also strengthened the understanding of village stakeholders regarding environmentally sound drainage management and groundwater conservation. In conclusion, the HIP system proved to be a feasible alternative to conventional vertical infiltration structures, particularly in areas with limited space and specific soil conditions. The installed system can serve as a pilot model for sustainable drainage management in Banyubiru, while routine maintenance and periodic monitoring are recommended to ensure long-term system performance and support groundwater recharge.
