Abstract

This study comprehensively evaluates the risk of Work-Related Musculoskeletal Disorders (WMSDs) among production operators at PT EMS, a company engaged in electronics manufacturing. Utilizing a mixed-methods ergonomic approach, the research employed the Nordic Body Map (NBM) to measure operators' subjective complaint levels and the Quick Exposure Checklist (QEC) to assess objective posture-related exposure risks. Analysis of NBM data revealed that the Printing station exhibited the lowest average complaint levels (5.6 total average complaints per operator), indicating better ergonomic conditions. Conversely, Wave Solder and Cutting Point operators reported the highest average total complaints (11.9 and 11.6, respectively), with the Wave Solder station registering the highest proportion of "Severe Pain" cases. The QEC analysis, which focused on the worst-case operator exposure, identified the Wave Solder station as the most critical, yielding the highest Exposure Score of 88% (Action Level 4), followed closely by Printing (78%) and Cutting Point (74%). The body parts most susceptible to injury across these high-risk stations were the Back (QEC score 44), Wrist (40), and Shoulder/Arm (36). The findings confirm that prolonged static posture, repetitive movements, and manual material handling are primary contributors to WMSDs prevalence. Immediate interventions are highly recommended, specifically the provision of push assistance tools, elbow supports, and footrests at the workstation to mitigate exposure risk and enhance occupational health.

Abstract

Marine debris is a serious problem, especially in the outermost, foremost, and least developed (3T) islands of Indonesia, where limited infrastructure and low public awareness are the main obstacles to effective waste management. This study aims to design, develop, and evaluate an Internet of Things (IoT)-based application integrated with a community-based web platform to support circular economy practices and community empowerment in marine debris management. The research method used is Research and Development (R&D) adapted from Borg & Gall, starting from the needs analysis stage to dissemination. An IoT module equipped with ultrasonic and GPS sensors is used to detect container capacity and location in real-time. Performance testing results show a response time of 1.8 seconds, a data transmission success rate of 98.7%, and a capacity detection accuracy of 96.2%, which meets the established technical standards. User acceptance testing using the Technology Acceptance Model (TAM) involving 15 respondents resulted in an average Perceived Usefulness (PU) score of 4.40 and Perceived Ease of Use (PEOU) of 4.23. Pearson's correlation analysis showed an r value of 0.84 (p = 0.0001), indicating a very strong and significant positive relationship between ease of use and perceived usefulness. This finding confirms that the developed system is technically reliable, easy to use, and capable of promoting environmental sustainability and economic opportunities in the 3T island communities.

Abstract

Plastic waste accumulation poses a severe environmental burden, particularly in urban and archipelagic regions where centralized treatment infrastructure is limited. While thermal processing offers a pathway for volume reduction and material recovery, inadequate temperature control frequently leads to uncontrolled combustion and the formation of hazardous air pollutants. This study addresses this gap by developing and experimentally validating a low-emission, IoT-enabled mobile plastic melting system designed for decentralized paving block production. The proposed system integrates real-time thermal sensing using a K-type thermocouple and an ESP32-based controller with a compact three-nozzle water spray filtration unit. The control architecture maintains the melting process at approximately 270 °C, thereby preserving polymer viscosity for molding while preventing temperature excursions beyond 300 °C that may initiate combustion and toxic by-product formation. The filtration module operates as a simplified wet scrubber, capturing airborne particulates and simultaneously cooling the exhaust stream. Experimental evaluations confirm that the integrated control–filtration framework achieves stable thermal regulation and substantial suppression of visible exhaust emissions. Under these conditions, molten plastic was consistently transformed into dense paving blocks with smooth surface morphology and without evidence of polymer degradation or charring. The results demonstrate that combining IoT-based thermal governance with low-cost water-spray emission control provides an effective and scalable alternative to open burning for community-level plastic waste recycling. This mobile platform enables environmentally safer conversion of plastic waste into value-added construction materials, offering a practical pathway toward decentralized circular-economy implementation in resource-constrained regions.

Abstract

Background: UMKM Batik di Batam menghadapi tantangan dalam kapasitas produksi, pemanfaatan teknologi, dan pemasaran produk, yang menghambat daya saing mereka. Program Pengembangan UMKM XYZ oleh PT PLN Batam bertujuan untuk memberdayakan pengrajin batik dengan memberikan dukungan peralatan, pelatihan, dan integrasi pemasaran digital, yang merupakan pendekatan baru untuk memperluas pasar produk batik Batam secara lebih efektif. Penelitian ini bertujuan untuk mengevaluasi dampak ekonomi dan sosial dari Program Pengembangan UMKM XYZ menggunakan pendekatan Social Return on Investment (SROI). Metode: Data dikumpulkan melalui observasi lapangan, wawancara, dan analisis SROI untuk mengukur dampak sosial dan ekonomi dari investasi yang diberikan PT PLN Batam. Hasil: Program ini menghasilkan nilai SROI sebesar 1,13, yang berarti setiap Rp1 yang diinvestasikan memberikan manfaat sebesar Rp1,13. Program ini meningkatkan pendapatan pengrajin batik sebesar 30% dan meningkatkan keterampilan serta pemasaran digital mereka. Inovasi utama dalam program ini adalah penerapan pemasaran digital yang berhasil memperluas jangkauan pasar dan meningkatkan daya saing UMKM XYZ, dengan dampak positif pada aspek ekonomi dan sosial.

Abstract

Background: Buluh Island, one of the coastal areas in Batam City, faces serious challenges in the fisheries sector due to the use of traditional fishing methods, which result in high operational costs, the risk of catch theft, and low productivity. This Community Service Program (PKM) offers a solution by applying GPS- and IoT-based Smart Fishing Technology, integrated with solar panels for energy. This technology enables fishermen to monitor the condition of their nets in real time, detect fish using sonar, and minimize travel, thereby reducing fuel consumption. Method: The program takes a participatory approach, involving fishermen from the socialization stage, training, device installation, and evaluation. Results: The implementation shows decreased operational costs, increased net safety against theft, and higher catch yields, which impact fishermen's income. Additionally, the program has successfully produced financial management training, video documentation, scientific publications, intellectual property rights, and educational posters. Kesimpulan: Smart Bagan is expected to be replicated in other coastal areas to support the sustainable welfare of fishing communities, in line with the achievement of SDGs 1, 2, 8, and 14.

Abstract

Background: Buluh Island, one of Batam City’s coastal islands, faces a serious challenge in plastic waste management. Approximately two tons of waste are generated every four hours, but limited waste processing facilities result in most waste being burned or dumped into the sea, polluting the ecosystem and reducing fish catches. This threatens the economic sustainability of local communities, most of whom are fishermen. Method: This community service program provides a solution by implementing an Internet of Things (IoT)-based plastic shredder powered by solar panels. The technology is designed to operate independently from the conventional electricity grid and enables real-time monitoring via the Blynk application. The shredded plastic is then processed into economically valuable products such as paving blocks and handicrafts, supporting a circular economy. The community was actively involved in planning, installation, training, and machine maintenance, with the Buluh Island Waste Bank as the main partner. Results: The results show a reduction in plastic waste accumulation, increased community awareness of waste segregation, and key outcomes, including machine installation, training, media coverage, video documentation, and a draft journal publication. Conclusion: There is limited access to spare engine components and dependence on weather conditions for solar energy availability.
