Abstract

This study evaluates the implementation of Occupational Safety and Health (OSH) practices at PT. PLN (Persero) UP3 Padang. The electricity sector faces significant OSH challenges, and while research has explored OSH in various settings, a gap remains in the evaluation of OSH practices within Indonesian office environments. This study aims to address this gap by evaluating OSH work environment implementation at PT. PLN (Persero) UP3 Padang based on the Indonesian Ministry of Manpower Regulation/ Pemenaker No. 5 of 2018. The research employs a primarily quantitative approach, utilizing a descriptive survey design. Data, gathered through questionnaires, assessed OSH implementation (based on Permenaker No. 5 of 2018), safety climate, and employee safety behavior. The results indicate that PT. PLN (Persero) UP3 Padang has demonstrated a strong commitment to OSH, achieving a generally high level of compliance with Permenaker No. 5 of 2018. Employees reported a positive safety climate, with high average scores for management commitment (approximately 3.55). Employee adherence to safe work practices was also high, although hazard reporting behavior received a lower average score of 3.56. Furthermore, the reporting and communication culture dimension within the safety climate was the lowest at 3.28. A strong positive correlation was found between safety climate and OSH implementation (ρ = 0.7218; p < 0.001). The study concludes that while OSH implementation is generally effective, there are areas for improvement, including controls for specific hazards and hazard reporting. Continuous improvement and targeted interventions are crucial for enhancing OSH performance within the organization and similar office settings.

Abstract

The tofu industry provides communities with affordable protein sources. As protein sources, the environmental impact of tofu production was compared to other protein sources. Further, the tofu industry also produces waste and by-products affecting the environment. Some previous studies learned the environmental impact of tofu production. In this study, we aim to get information on which stages of the process in the tofu industry impact the environment and what type of strategy is applied to reduce the environmental impacts. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) approach was then chosen to filter the most recent research publications published in international peer-reviewed journals. We found that most articles calculated the environmental impact based on GHG, which contributed mainly from imported soybeans and electricity used during production. This research can act as a foundation for further studies related to the tofu industries, enabling treatment, better strategies, and solutions for waste to be developed.

Abstract

Kontaminasi air oleh mikroorganisme patogen merupakan masalah kesehatan global yang membutuhkan solusi disinfeksi yang efektif dan mudah diakses. Penelitian ini bertujuan untuk fabrikasi agen antimikroba ramah lingkungan berbasis Lapisan Ganda Hidroksida (layered double hydroxide/LDH) pada substrat aluminium foil yang mudah diproduksi dan diaplikasikan untuk disinfeksi air. Morfologi seperti lembaran memungkinkan pengambilan kembali LDH yang pada dasarnya berbentuk bubuk, dari air yang telah disterilkan sebelumnya secara batch. Pelapisan foil aluminium dengan Mg-Al LDH dicapai dengan merendamnya dalam larutan magnesium alkali, yang menghasilkan pembentukan LDH di permukaan. Material yang dihasilkan dikarakterisasi menggunakan Difraksi Sinar-X (XRD) dan Mikroskopi Elektron Pemindaian (SEM) untuk menganalisis struktur kristal dan morfologi permukaan Uji aktivitas antimikroba menunjukkan bahwa material LDH pada aluminium foil memiliki kemampuan menghilangkan Eschericia coli dengan efisiensi penyisihan mencapai 90,9% dalam waktu 3 jam. Studi ini menunjukkan bahwa LDH pada aluminium foil berpotensi diaplikasikan sebagai agen antimikroba ramah lingkungan dan praktis untuk disinfeksi air, seperti air ceret dalam skala rumah tangga.
