Abstract

Abstract. Rawapening Lake is located in Semarang District, Central Java. The decreasing of Rawapening lake function due to its many problems caused by environmental degradation which has happened for almost three decades.  Buffer zone determination is a very important basic action to safe Rawapening Lake. This research is to determine Rawapening lake buffer zone and its management. Hydraulic, topographic analysis was conducted within the research along with identification of buffer zone condition. A clear buffer zone area act as boundary for Rawapening lake utilization to support the sustainability of its function in the future.

Abstract

PT Pelindo Multi Terminal is a company engaged in loading and unloading services for liquid bulk, dry bulk and containers. Hazard Identification, Risk Assessment and Risk Control (HIRARC) is a method for identifying potential hazards that exist in each type of work. The aim of this research is to determine hazard identification, risk assessment and risk control using the Hazard Identification, Risk Assessment and Risk Control (HIRARC) method at PT Pelindo Multi Terminal. Research was carried out on all aspects of each liquid bulk to dry bulk operation which have the potential to cause accidents and occupational health. Data collection techniques are field observation, interviews and documentation. Descriptive data analysis using the HIRARC model with comparison of the effectiveness of IBPR. The results of the research show that IPBR risk control in the low risk category shows an increase in the presentation of signs of success in risk control, in this case there is an increase in the low risk category by 55%, while HIRARC risk control in the low risk category shows an increase in the presentation of signs of success in risk control. , in this case there is an increase in the low risk category by 90%, in this case it can be seen that HIRARC is more effective in controlling work risks. PPE equipment is adjusted to the type of work being carried out because there are still inconsistencies in wearing PPE. Keywords: Hazard Identification, Risk Assessment, Risk Control, HIRARC.

Abstract

This study aims to analyze the effectiveness of the Liquefied Petroleum Gas (LPG) loading and unloading process at PT Pertamina Energy Tanjung Sekong Terminal, a key infrastructure in Indonesia's national energy distribution. The evaluation was based on technical and operational indicators, including the Berthing Occupancy Ratio (BOR), Length Over All (LOA), berthing time, cargo volume, and vessel visit frequency. The results show that BOR ranged between 55–65%, indicating efficient jetty utilization. The average vessel LOA was 120 meters, matching the jetty’s capacity. The average berthing time was recorded at 18 hours per visit, with unloading volumes between 2,500–3,000 metric tons and vessel frequency ranging from 8 to 10 visits per month. The main constraints affecting effectiveness included extreme weather, technical equipment failures, and limited supporting facilities. This study recommends improving equipment maintenance, strengthening operational coordination, and developing a risk management system to ensure smooth and sustainable LPG handling operations at the terminal.
