[ABSTRAK
Tesis ini membahas tentang bahaya, risiko serta mitigasi keselamatan dan kesehatandalam pengembangan biogas skala kecil dari bahan baku kotoran sapi. Penilaianrisiko dilakukan dengan cara mengukur komposisi biogas, identifikasi danperhitungan jumlah bakteri, identifikasi dan perhitungan telur cacing dan observasikegiatan pembuatan biogas. Data penelitian diolah secara semi kuantitatif sehinggadiperoleh nilai risiko keselamatan dan kesehatan pada penggunaan reaktor biogasskala kecil. Risiko keselamatan tertinggi adalah terjadinya ledakan, sedangkan risikokesehatan tertinggi adalah keracunan H2S. Mitigasi yang disarankan adalah: a)eliminasi dengan penghilangan blower, b) enjinering kontrol dengan modifikasi dibak pengaduk dan membuat pelindung digester serta c) tindakan administratifdengan melakukan edukasi terhadap peternak.
ABSTRACT
This thesis discusses the hazards, risks and mitigation of safety and health in thesmall-scale biogas digester from cow manure feedstock. Risk assessment is done bymeasuring the biogas composition, identification and calculation of the amount ofbacteria, identification and calculation of worm eggs and observation activities of thebiogas production. Data were analyzed semi quantitatively in order to obtain thevalue of safety and health risks of the application of a small-scale biogas digester.The highest safety risk is the explosion, while the highest health risk is H2Spoisoning. Suggested mitigation are a) elimination by removing blower from system,b) control engineering by considering modifications in the mixing basin, builddigester protective and c) administrative action by educating farmers.;This thesis discusses the hazards, risks and mitigation of safety and health in thesmall-scale biogas digester from cow manure feedstock.
