Abstract

Bawah Reserve berhasil memperkenalkan energi terbarukan ke pulau terpencil ini dengan menginstal panel surya di hotel. Dengan komitmen terhadap keberlanjutan, hotel ini dirancang secara cermat dengan pendekatan 'dampak minimal'. Selain itu, Bawah Reserve berdedikasi untuk pelestarian dan konservasi kedua ekosistem daratan dan laut, sambil aktif memberdayakan komunitas pulau setempat.Struktur panel surya terapung adalah cara brilian untuk mengeksploitasi kekuatan matahari di tempat-tempat yang langka tanahnya seperti pulau dan kota pesisir yang padat, memungkinkan energi surya yang hampir tak terbatas diproduksi. Dengan menyediakan akses ke energi bersih dan terbarukan ini, panel surya fotovoltaik mengurangi ketergantungan mereka pada sumber energi konvensional yang mencemari dan seringkali mahal. Bawah Reserve bangga menjadi perintis integrasi teknologi mutakhir dengan pelestarian ekologis dalam industri perhotelan. Panel energi surya mengapung dengan anggun di laguna, memanfaatkan energi matahari untuk menghasilkan listrik ramah lingkungan. Dengan mengurangi jejak karbon resor dan melindungi lingkungan alam, panel-panel ini tidak hanya memberikan naungan tetapi juga berkontribusi dalam mengatur suhu air dan melindungi kehidupan akuatik.

Abstract

This study delves into the biomechanics of lifting dumbbell and jumping movements, pivotal exercises in resistance training and fundamental for various activities, employing the Kinovea application. Twenty male and female participants from Institut Teknologi Batam's Industrial Engineering study program underwent protocols recorded by a Sony HDR-CX405 camera. Kinematic analysis measured parameters using the Kinovea application, revealing participants' mean age, height, and weight. Dumbbell lifting entailed a mean distance of 0.45 ± 0.05 m and joint angles at shoulder (157.50 ± 5.77°), elbow (146.25 ± 6.25°), and wrist (45.00 ± 5.77°). Jumping achieved a mean height of 35.50 ± 2.87 cm, with joint angles at ankle (25.00 ± 5.77°), knee (90.00 ± 5.77°), and hip (120.00 ± 5.77°). Findings aligned with previous studies, emphasizing joint angles' importance. Implications include exploring muscle activation patterns and metabolic demands for future research and informing tailored training programs to enhance lifting and jumping abilities, offering valuable insights into biomechanics for sports and exercise training applications.

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.
