Setiap kegiatan termasuk kegiatan transportasi mempunyai risiko terjadinya kecelakaan kerja. Transportasi sungai menggunakan Smallboat memiliki risiko terjadinya kecelakaan, khususnya yang berkaitan dengan bahaya perairan. Terdapat beberapa kecelakaan didalam transportasi sungai menggunakan Smallboat. Tujuan Penelitian iniuntuk mengetahui bahaya-bahaya dan tingkat risiko yang ada dalam transpotasi sungai menggunakan Smallboat. Penelitian ini menggunakan desain deskriptif observasional,JHA (Job Hazards Analysis) untuk identifikasi bahaya dan metode penilaian risiko semikuantitatif. Hasil penelitian menunjukkan tingkat risiko diawal cukup tinggi untuk beberapa kategori bahaya, terutama untuk bahaya yang berhubungan dengan perairan(Marine Hazard) tabrakan, drifted (akibat gagal mesin), pengikatan tali mooring, sampaibahaya orang jatuh ke air (dengan nilai risiko All work activity include transportation have a risk of accident. Small boat Marine(river) transportation have a specific risk of accident, especially regarding marinehazards. There were many accidents happen regarding small boat transportation. Thepurpose of this study is to know what kind/type of hazards and level of risk from smalltransportation activity. This study uses design of observational descriptive, Job HazardAnalysis (JHA) for identify hazards tools and semi quantitative for risk assessmentapproach/technique. The result showed that there have high level of risk assessment fromseveral specific hazards (regarding marine hazards), specially related with collision,drifted (engine failure), mooring line, and until man overboard (with result is more than350 which is very high category risk level). With some existing and recommend actionfor mitigation from author to reduce risk level from the activity the result can be reduceuntil low category (priority 3, substantial and acceptable risk level). The author suggestedthat mitigation action (procedural, training and engineering control) should implementedand perform other risk assessment for the others work area location.Keywords: Risk, Marine Hazards, River Transportation, Smallboat
