Kegiatan pengabdian ini bertujuan untuk membuat pembangkit listrik yang berasal dari sampah organik di TPA Cilowong, Kota Serang Banten. TPA Cilowong merupakan tempat pembuangan pusat sampah yang berasal dari seluruh daerah yang ada di wilayah Kota Serang Banten. Setiap harinya TPA ini menerima 5 truk sampah pasar yang dibuang pada landfill dan belum dimanfaatkan secara optimal. Padahal sampah ini dapat diolah menjadi biogas untuk penerangan listrik TPA dan bahan bakar kompor di dapur umum TPA. Instalasi biogas dibuat dengan satu digester (penampung biogas) berbentuk bulat yang bisa menampung sampah sebesar 6 m3. Untuk pertama kali pemakaian, dibutuhkan starter kotoran sapi yang dicampur dengan sampah organik pasar sebagai starter dengan perbandingan sampah : kotoran sapi = 5: 1. Kegiatan ini bekerja sama dengan 30 orang mahasiswa KKM dan pengurus TPA Cilowong. Biogas dari sampah ini bisa digunakan untuk penerangan listrik di TPA dan sebagai sumber gas di dapur umum TPA.
Several previous studies have stated that there are several risk factors that affect musculoskeletal disorders on construction workers. Most of the studies have reported the existence of individual and physical risk factors, but only few studies have focused on psychosocial risk factors. The present study included 45 construction workers of a building construction project. A self-reported measurement questionnaire was used to determine the prevalence of musculoskeletal symptoms. The results showed that shoulder pain was most felt by workers during the last seven days and the last 12 months. Regarding to the prevalence felt during the last seven days, factor of reward was significantly associated with knee pain (OR: 0.09; 95% CI: 0.01-0.99). Regarding to the prevalence felt during the last 12 months, factor of weight was significantly associated with upper back (OR: 1.11; 95% CI: 1.01-1.22) and shoulder (OR: 1.09; 95% CI: 1.00-1.18). Body mass index was significantly associated with upper back (OR: 1.35; 95% CI: 1.01-1.22) and shoulder (OR: 1.31; 95% CI: 1.01-1.71). Results of this study indicated that psychosocial risk factors have significant roles in developing musculoskeletal disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
