Abstract

The city of Samarinda plays a vital role as the main contributor to the country's foreign exchange through the coal mining and oil palm plantation sectors. Thanks to this region's high-calorie coal content, Samarinda is often the centre of land disputes. This service activity aims to provide counselling and training regarding geographic information systems to Vocational High School (SMK) students in Samarinda. Global Positioning System (GPS) technology plays a vital role in this program, considering its ability to determine location coordinates on the Earth's surface. This training introduces Garmin GPS to students, covers its features and functions, and explores student responses to the training material. The methodology includes counselling and direct practice in the field, with students' understanding and perceptions evaluated through pre-tests and post-tests. The evaluation results show that the training program increased participants' understanding, skills and acceptance of mapping concepts. It was also noted that there was a decline in student enthusiasm and participation after the training. The geographical conditions of Samarinda, characterized by wide rivers, swamps, hills, ravines, and a fluctuating climate, add to the challenges in collecting coordinate point data. Therefore, intensive mentoring is an essential key to ensuring the sustainability and effectiveness of this program in the future.

Abstract

The tofu Micro, Small, and Medium Enterprise (MSME) sector constitutes a vital agro-industrial component that significantly contributes to food security and local economic development. Nevertheless, its sustainability remains constrained by inefficient resource utilization and suboptimal waste management practices. This study aimed to develop an integrated Green Productivity–Fishbone Diagram model to optimize waste management while enhancing sustainable productivity in tofu MSMEs in Samarinda, Indonesia. A descriptive quantitative approach was employed through field observations, structured interviews, documentation, and direct measurements. Productivity performance was assessed using Key Performance Indicators (KPIs), whereas environmental performance was evaluated through the Environmental Performance Indicator (EPI). The findings revealed a production capacity of 1,650 units per month, a financial productivity index of 1.1165, and an improvement in productivity from 104.9% to 107.4%. A multi-stage filtration system utilizing coconut shell activated carbon effectively reduced COD concentrations from 1,449.162 to 213.945 mg/L and BOD from 136.79 to 135.50 mg/L, achieving removal efficiencies of 85.24% and 0.95%, respectively, while increasing pH from 3.68 to 6.59, thereby complying with the applicable wastewater quality standards. The proposed model substantially improves resource efficiency, strengthens environmental performance, and supports the implementation of circular economy principles for sustainable tofu MSME development.
