Abstract

The impact of landfilling is the emergence of leachate which contains suspended and dissolved solids, organic and inorganic chemicals which are quite high and have the potential to cause environmental pollution. The lack of variety of leachate treatment makes many researchers start looking for effective ways to reduce leachate. One of the methods proposed is to use decomposer organisms, namely Black Soldier Fly (BSF) insects. The purpose of this study was to determine the effectiveness of Black Soldier Fly (BSF) larvae in processing leachate from organic waste from TPS. The research method used growing media or a mixer in the form of chicken feed and variations in leachate concentrations, namely 25%, 40%, 55%, 70%, 85%, and 100% (L25, L40, L55, L70, L85, and L100). The results showed that Black Soldier Fly (BSF) larvae were quite effective in processing leachate for 22 days. The concentration of leachate is quite influential in leachate processing, the greater the concentration, the higher the level of effectiveness. The effectiveness of leachate treatment using BSF larvae is based on the highest media weight loss, namely in the L100 treatment, which is 57.13% and the lowest in the L25 treatment, which is 48.49%.

Abstract

The importance of K3 in the tugboat bunkering process is not only limited to safety aspects, but also has a direct impact on ship readiness. Implementing good K3 ensures that bunkering is carried out in accordance with existing procedures. In addition, implementing good K3 will support the operations of ships that have been bunkered so that the ship can continue to operate effectively in supporting various maritime transportation needs. The research method used is the HIRADC (Hazard Identification Risk Assessment Determining Control) method. HIRADC is a method of risk management. For data collection techniques in this research, field observations, interviews and company data were used. In this data analysis and discussion, an analysis of the data processing that has been carried out will be carried out, namely identifying potential risk values ​​and considering the risk ranking to determine priorities and methods of control. After the data analysis and discussion, the next step is to draw conclusions from the data analysis that has been carried out. In the process of filling a ship with fuel (bunker), various dangers or risks can arise throughout the stages of the activity. Hazard identification involves recognizing and documenting the various potential elements that could cause an accident or health problem. For example, slipping, being pinched, being hit by a fuel pump hose during the bunkering process are also aspects that need to be identified as dangers. The work activity identified in this research is the activity of filling the ship with fuel (bunker), then carrying out a risk assessment of the work activity, then determining the necessary hazard and risk controls with the aim of preventing accidents. Data processing will be carried out using the HIRADC method. This step will later become input and suggestions that can be implemented at PT Pelindo Marine Service as a reference for determining steps to deal with work accidents that occur. The importance of identifying hazards in ship bunkering activities is to develop effective prevention strategies and ensure that appropriate safety measures are taken. For example, if hazards related to slips and falls are identified, measures such as special training for operators, use of personal protective equipment (PPE), and strict implementation of standard operating procedures (SOPs) can be impl
