Abstract

Automatic fertilizer mixing is required to minimize fertilizer and water mixing time because manual liquid mixing takes a long time. The fertilizer used is liquid, often known as effective microorganisms 4 (EM4) solution. To perfect the stirrer, which is still rotated manually, the DC motor provides speed control for the automatic liquid fertilizer mixer. The speed can be reduced by utilizing the Arduino Uno microcontroller so that the motor rotates according to the required speed. The main mechanical components consist of a DC motor, Arduino Uno as a microcontroller, a power supply as a source of electric current, and a container for mixing liquid fertilizer. The infrared (IR) sensor achieved high accuracy in measuring mixer rotational speed for EM4 fertilizer, with percentage errors ranging from 0.2% to 1.8% compared to tachometer readings. However, when applied to green fertilizer, the error rates varied widely, from 0.03% up to 28.05%, indicating significant fluctuations. These results highlight that the IR sensor is quantitatively reliable for EM4 fertilizer applications but requires further calibration to ensure consistent performance with other fertilizer types

Abstract

River water plays an important role in human life. Along with the increasing population and waste problems generated from human activities, climate change is a factor that also affects river water quality. Blankahan Village is located in Langakat District, with 3 interconnected rivers, Palma River, Pekan Kuala, and Dosi Valley. This program examines the impact of river water quality on public health in Blankahan Village, with a focus on physico-chemical and social health analysis to support the achievement of SDGs points 3 and 6. It was found to be in a fairly poor and murky condition according to the classification according to Government Regulation Number 22 of 2021. Furthermore, based on statistical tests and One Way ANOVA Tests indicated that there was no statistically significant difference in the mean perception among the age groups. Some indicated women's health problems due to river water use such as dermatitis, skin diseases, and diarrhea continue to increase. River water sources are still used by some communities to fulfill household needs during the dry season despite many negative perceptions that river water quality is poor, dirty and polluted with waste. River water quality is influenced by seasonal factors and pollution, namely the difference in river water quality during the rainy and dry seasons, and is also caused by domestic waste, livestock waste, and industrial waste entering the water.

Abstract

This community service program involves innovative waste management based on appropriate technology, utilizing the smart waste management concept, which processes agricultural and livestock waste into renewable energy sources such as organic fertilizer. The program was conducted in Bekiung Village, Kuala District, Langkat Regency, where cow dung and palm oil waste are the primary waste products. Through composting or co-composting, these two products can be converted into high-quality organic fertilizer that improves soil fertility. The core of the community service program is to create a community-based, sustainable waste management model that integrates simple technology, training, and mentoring. The goal is to reduce pollution, boost the local economy through waste-based industries, and support renewable energy and socio-ecological sustainability for the well-being of the village community.

Abstract

This study explores the implementation of a holistic community service program in Siponjot Village, North Sumatra, aimed at enhancing non-formal education, economic sustainability, and environmental resilience. Through the "Marsiajar Manang Didia Pe" initiative, the program promotes a flexible learning system aligned with local cultural values, addressing gaps in formal education. Key components include training in agricultural practices focusing on coffee and mahogany cultivation alongside the introduction of data-driven decision making tools such as economic mathematical models and QR codes for improved information management. Results indicate improved community engagement, increased agricultural productivity, and enhanced digital literacy. The findings highlight the critical interplay between education, technology adoption, and sustainable practices in fostering community empowerment and resilience against environmental challenges.
