Abstract

Biogas adalah gas yang berasal dari kotoran ternak/manusia yang mudah terbakar. Proses pembuatannya yakni memfermentasi kotoran tersebut dengan memanfaaatkan mikroorganisme anaerob (Wahyuni, 2013). Kandungan utama biogas adalah karbon dioksida dan metana (CH4) dalam kotoran sapi yang tinggi, yaitu nilai kalor berkisar 4.800 – 6.700 kkal/m3. Pemanfaatan biogas sebagai energi terbarukan guna meningkatkan kualitas SDM dan perekonomian sangat penting dilakukan bagi desa yang didominasi sektor peternakan dan peternakan, seperti halnya pada Desa Madureso, Mojokerto. Upaya pemberdayaan masyarakat dalam pemanfaatan limbah kotoran sapi menjadi biogas dan pupuk organik ini melibatkan Kelompok Tani Jaya. Rangkaian kegiatan pengabdian masyarakat yang dilaksanakan oleh Tim P2MD Himpunan Mahasiwa Keselamatan dan Kesehatan Kerja Universitas Nahdlatul Ulama Surabaya, yaitu dimulai dengan melakukan koordinasi dengan pihak Desa Madureso dan Kelompok Tani Jaya untuk selanjutnya dilakukan oleh sosialisasi terkait gambaran umum biogas, mengumpulkan warga desa ikut turut serta dalam pembangunan instalasi. Sebelum melakukan pengoperasian instalasi biogas, dilakukan pelatihan pembuatan biogas dari tahap pengisian biodigester, proses pengadukan, fermentasi, hingga output berupa gas dan pupuk. Dari keseluruhan rangkaian kegiatan pengabdian, sambutan masyarakat sangat baik dan antusias untuk membantu terlaksananya kegiatan pengabdian. Hal ini terbukti dengan tingkat partisipasi masyarakat yang tinggi serta kesediaan warga Desa Madureso untuk mendukung terlaksananya kegiatan ini. Diharapkan, monitoring dan evaluasi terus dilakukan, sehingga nantinya kendala atau permasalahan yang ditemui dalam proses pemanfaatan limbah kotoran sapi menjadi biogas ini dapat diatasi secara mandiri oleh warga setempat.

Abstract

One of the risks that can occur in the workplace is the risk of physical factors, namely noise. The physical environment is one of the important factors to play a role in the occurrence of work accidents. The role of factors in the work environment is very large with the occurrence of Occupational Safety and Health problems. To create a safe and comfortable work environment, it is necessary for workers and companies to apply Occupational Safety and Health when doing work. Noise is an unwanted sound in the work area due to production equipment or production machinery. The results of the initial survey through observation and hazard assessment using JSA and calculation using the CARL method. It was found that the highest risk assessment was the physical factor of noise. Therefore, the purpose of community service is carried out to prevent the existence of physical factor hazards, namely noise. Taking measurements using a Sound Level Meter, from the results of noise measurements that have been taken, there are work areas that exceed the Threshold Value (NAB), which gets a value of 87.92dB. It can be concluded that there is a high value of noise intensity, it should receive attention by controlling hazards that can be applied to the informal sector of PT.X, namely reducing production machine tools on the floor and moving them to the next floor, it can also be controlled by using Personal Protective Equipment (PPE), namely ear plugs when all production machine tools are operating.

Abstract

Cow dung is a waste that can interfere with environmental aspects. Constantly increasing volumes without treatment can interfere with human health. This problem is still a challenge for Madureso Village, Mojokerto Regency, East Java. Economic activity is dominated by the agricultural and plantation sectors. About 70% work as farmers or ranchers, but Madureso Village does not have a different cow dung processing system. To overcome this problem, the P2MD team of the Occupational Safety and Health Student Association of Nahdlatul Ulama University Surabaya initiated waste treatment by processing cow manure into biogas and organic fertilizer. Later, the biogas can be an effort by the local community in Madureso Village, to care about environmental hygiene problems and alternative fuels. Therefore, community service activities are carried out through socialization regarding biogas processing or production. The evaluation of the socialization that has been carried out is that most participants understand the importance of cow dung processing and how to utilize the results of this waste treatment. Thus, it is hoped that the community can carry out biogas processing independently and sustainably. Based on the results obtained during the community service activities, it can be seen that the socialization activity was successful because it has increased participants' understanding of biogas. There was an increase of 94% in post-test results where previously only 61% of respondents knew about biogas.
