Abstract

Risk management is a crucial aspect of Occupational Health and Safety (OHS) implementation at PT X, which operates in the livestock sector. The implementation of risk management in this company remains limited and has not been effectively operationalized. This research aims to provide a foundational step and evaluation material to minimize workplace accidents. The method used in this study is HIRARC, which is effective and efficient in identifying potential hazards, conducting risk assessments, and controlling risks. PT X comprises several departments with both minor and major hazard potentials. This study focuses on the Milking Department, which is vital in milk production. The assessment was conducted by analyzing all existing processes and activities results show that low risk accounts for 75%, medium risk for 25%, and high risk for 0%. Risk control is implemented through a hierarchy of controls. The application of this hierarchy of controls can minimize the existing risk levels. Overall, the implementation of OHS at PT X has not been optimal and requires further improvements as a foundational step in OHS implementation and evaluation, as well as to meet the requirements for the Occupational Health and Safety Management System (OHSMS) development.

Abstract

The decline in water quality due to the presence of chemical elements that exceed safe limits in the environment is caused by human activities. One of the main causes of pollution is the use of heavy metals such as chromium in various industries without adequate treatment, making it one of the most harmful pollutants. In addition, liquid waste containing surfactants from synthetic detergents can form foam bubbles that are difficult to remove and interfere with gas exchange between water and the atmosphere, thus exacerbating pollution. This study aims to assess the level of acute toxicity and analyze the classification of compound heavy metals Chromium (Cr) and Linear Alkylbenzene Sulfonate (LAS) that can cause death in zebrafish (Danio rerio). The research process includes the stages of adjusting the test biota, Range Finding Test (RFT), and Acute Toxicity Test (ATT). The concentrations employing in the acute toxicity test (ATT) were P1 (0 ppm), P2 (6.4 ppm), P3 (9.0 ppm), P4 (12.5 ppm), P5 (17.6 ppm), and P6 (25.6 ppm). This research is an experimental study that employing probit analysis to calculate the LC50 value. The results of acute toxicity analysis showed that the LC50 value for compound heavy metals Chromium (Cr) and LAS was 11.46 ppm. Based on the chemical hazard classification and labeling by the US EPA in 2004, this LC50 value is included in category IV, which indicates that compound heavy metals Chromium (Cr) and LAS are classified as relatively harmless.
