[ABSTRAK Analisis Risiko Kesehatan Lingkungan Akibat Pembuangan Limbah CairPembangkit Listrik Tenaga Panas Bumi (PLTP) Ulumbu ke Sungai (Pada LapanganPanas Bumi Ulumbu, Kabupaten Manggarai, Nusa Tenggara Timur)Pembangkit Listrik Tenaga Panas Bumi (PLTP) merupakan salah satu sumberenergi yang ramah lingkungan karena menghasilkan volume limbah yang rendah,salah satunya adalah limbah cair. Limbah cair panas bumi mengandung unsurkimia, salah satunya adalah Arsen. Limbah cair PLTP akan menimbulkan dampakapabila dibuang secara langsung ke sungai. Tujuan penelitian ini adalah untukmengidentifikasi besarnya konsentrasi Arsen pada limbah PLTP dan air sungai dilokasi penelitian dan dampaknya terhadap konsentrasi Arsen di sungai serta dampakterhadap kesehatan lingkungan. Dari penelitian ini didapatkan hasil konsentrasiArsen pada limbah PLTP sebesar 0,0365 mg/l. Kandungan Arsen dalam limbahyang dibuang masih berada di bawah baku mutu, yaitu sebesar 0,5 mg/l.Pembuangan limbah cair PLTP ini juga tidak meningkatkan konsentrasi Arsen disungai. Konsentrasi Arsen pada air yang dikonsumsi masyarakat adalah 0,008 mg/l.Perhitungan risiko kesehatan masyarakat yang mengkonsumsi air sungaimenunjukkan tidak menimbulkan risiko kesehatan RQ < 1 (RQ = 0,6522). ABSTRACT Geothermal power plant is one of the green energy which produces low wastevolume, including wastewater. Geothermal wastewater contains Arsenic, adangerous chemical. It can generate impact when it is discharged to the rivernearby. The purpose of this research is to identify Arsenic concentration in thegeothermal wastewater and in the river on the research location. The result of thisresearch shows that geothermal wastewater Arsenic concentration is still below theregulation, that is 0,0365 mg/l. Its content in the discarded waterwaste is still belowthe quality standar, which is 0,5 mg/l. Geothermal wastewater discharge has noeffect to the Arsenic concentration in the river. Arsenic concentration in the riverthat people consume is 0,008 mg/l. Based on this concentration, health riskassessment ot the comunity who consume the water from the river shows noharmful potential to cause health problem as the RQ less than 1 (RQ = 0,6522).;Geothermal power plant is one of the green energy which produces low wastevolume, including wastewater.
