Abstract

Food and beverage packaging waste is the predominant category of household waste on the Widyatama University campus. Responsibility for waste management lies with Widyatama University and requires collaboration from diverse stakeholders, including producers. Waste management employs various methods. The research endeavors to construct a waste management model utilizing concepts of green logistics and extended producer responsibility (EPR) to bolster the green campus initiative by harnessing packaging waste potential. The green logistics concept runs a series of processes—reduction, recycling, reuse, and material substitution—directed at packaging waste and transportation to a Waste Bank. EPR concept incorporates policies incentivizing environmentally-conscious product creation, expanding the producer's responsibility. This concept extends to collaborations with small and medium enterprises (SMEs) around campus. Research simulations demonstrate a substantial reduction in waste volume, from 144 m3 to 72 m3 annually. The cost of waste management decreases by Rp11,352,400 from Rp36,244,800 to Rp24,872,400 annually, resulting in an efficiency of 31.34%.   Abstrak Sampah kemasan makanan dan minuman merupakan jenis sampah rumah tangga terbesar di kampus Universitas Widyatama. Pengelolaan sampah itu menjadi tanggung jawab pihak Universitas Widyatama dan memerlukan keterlibatan dan dukungan dari berbagai pihak, termasuk pihak produsen. Pengelolaan sampah dapat dilakukan dengan beberapa metode. Tujuan penelitian ini adalah membuat model pengelolaan sampah dengan pendekatan konsep green logistics dan extended producer responsibility (EPR) untuk mendukung green campus melalui pemanfaatan limbah kemasan makanan dan minuman di lingkungan Universitas Widyatama. Konsep green logistics diterapkan dengan rangkaian proses reduction, recycle, reuse, dan subsitusi material pada sampah kemasan dan pengirimannya ke Bank Sampah. Konsep EPR memiliki prinsip kebijakan yang mendorong sistem penciptaan suatu produk dengan mempertimbangkan aspek lingkungan dari sisi daur hidup produk tersebut dengan cara memperluas tanggung jawab produsen. Konsep ini diterapkan melalui kolaborasi dengan usaha mikro kecil dan menengah (UMKM) di sekitar lingkungan kampus. Dari simulasi pada penelitian ini diperoleh penurunan volume sampah dari 144 m3 menjadi 72 m3 per tahun. Biaya pengelolaan sampah turun sebesar Rp11.352.400 dari Rp36.244.800 menjadi Rp24.872.400 per tahun, sehingga diperoleh efisiensi sebesar 31,34%.

Abstract

The demand for achieving zero accident targets, coupled with various urgent tasks and frequent overtime work, has the potential to increase workload and stress among employees in the K3L (Occupational Health, Safety, and Environment) division at PT PLN (Persero) West Java Distribution Main Unit. Although the company has measured workload using work analysis forms and psychosocial assessments, this approach is considered to not fully represent the actual conditions as it primarily focuses on time aspects and stress levels. This research aims to complement the company's existing workload measurement methods with the Subjective Workload Assessment Technique (SWAT), which considers three main dimensions that is time load, mental effort load, and psychological stress load. The measurement results indicate that the mental effort load dimension has the highest percentage at 34.85%, followed by psychological stress load at 33.20%, and time load at 31.95%. These findings suggest that mental effort load is the dominant factor influencing the mental workload of K3L employees. Based on these results, this research provides recommendations for improvements focused on evaluating and adjusting administrative workload and strengthening managerial support. It is hoped that implementing these proposals can reduce mental workload and foster a more balanced, healthy, and productive work environment.
