The construction sector, for instance, is a common setting where these MSDs occur due to non-ergonomic practices. Several factors, including work posture and smoking habits, play a role in influencing the onset of Musculoskeletal Disorders (MSDs). Construction workers may experience MSDs as a consequence of unfavorable work postures that lack ergonomic considerations. The aim of this investigation is to explore the interconnections between work posture, smoking habits, and complaints of Musculoskeletal Disorders (MSDs) among the construction workers at the Dewi Sinta Residence housing project in Gunung Kidul Regency.This study employs a cross-sectional quantitative approach and was conducted at the Dewi Sinta Residence housing project in Gunung Kidul Regency, involving 60 participants.

2023-10-26T07:46:31+00:00

According to Menurut BPJS Ketenagakerjaan (Social Security Management Agency of Manpower), there has been a constant increase in occupational accidents in the last 7 years, where by 2022 it reached 265.334. The NPK factory of PT X is a petrochemical factory that produces NPK fertilizer. In it's production process, it needs nitrogen, phosphate, kalium and clay as it's raw materials. In addition to the chemical materials for it's production purposes, PT X utilizes modern machineries to make the process easier. From this description, it can be concluded that the production of NPK fertilizer would create a number of hazards which may lead to occupational accidents (OA) as well as occupational diseases (OD). This study aims to analyze the OSH risks which are present at the NPK factory of PT X using the method of Hazard Identification Risk Assessment and Risk Control. This is a quantitative study with observational descriptive approaches. It was found out that before the implementation of risk control, the NPK factory of PT X had the extreme risk rate of 75%, high risk rate of 14%, and medium risk rate of 3% from the total of 28 existing hazards (100%). Upon the implementation of control on the 28 hazards, PT X experienced the decrease in risk rates as follows: high risk 11%, medium risk 23%, and low risk 7%. Keywords: OSH risk analysis, Hazard Identification Risk Assessment And Control.

Background: A number of tourist villages in Sleman Regency are located in Disaster Prone Area (DPA). To minimize the risks of disasters, preparedness efforts are required.

Tourist Villages of Pentingsari, Nganggring, and Tunggularum are located in Merapi Disaster Prone Area (DPA). These three tourist villages were selected due to their high vulnerability and risk potential of Merapi eruption due to their locations in DPA III and DPA II. Methods: This is a qualitative study with case study design. The subjects of the study were tourist village organizers who had knowledge and understanding of tourist villages with the criteria of their positions in the tourist village organization. The sample taking technique applied to the subjects was the purposive sampling technique. Results: The level disaster preparedness in terms of knowledge parameter among some tourist village organizers was limited since only few things were understood. In terms of policy and guidelines parameter, these components were not available for the tourist village organizers. With regard to the parameter of emergency plan for the organizers, this component was limited since there were some lack of preparation in a number of components.
