Abstract

PT. McDermott Indonesia is a company engaged in offshore construction services. Workplace accidents in the offshore construction industry are often due to poor weather conditions, inadequate work locations, equipment failures, and incompetent employees. This study aims to determine the risk level in the rigging and lifting process using the HIRARC method as an effort to achieve zero accidents in the Production Platform Module Erection Area. This research uses a descriptive qualitative approach. The research subjects consist of 5 informants: a rigging superintendent, an HSE specialist, a rigger, a crane operator, and a mechanic foreman, assisted by interview guidelines and a risk matrix. The study results indicate 21 potential hazards across 4 work stages and 10 work processes, categorized into 6 low risk, 8 medium risk, 13 high risk, and 4 extreme risk. Risk control is carried out by HSE procedures and the lifting plan, and it is recommended to use PPE consistently. In conclusion, the risk analysis in the rigging and lifting process has been conducted according to procedures, but updates to the TRA are necessary to reduce increasing risks. It is recommended to enhance employee awareness and discipline regarding the importance of implementing HSE measures.

Abstract

This study, titled “Modification of Power Sprayer into a Pest Spraying Tool for Citrus Plants (Citrus Sp),” was conducted in Gunuang Omeh Sub-district, Lima Puluh Kota Regency, from September to October 2024. The objective was to assess the efficiency of a power sprayer and the effectiveness of pest control on citrus plants. The research involved modifying the nozzle of the power sprayer and conducting field tests on a 20 x 20 meter plot. Observations included flow rate, insecticide output capacity, spray distribution, operator walking speed, theoretical field capacity, effective field capacity, spraying efficiency, wind speed, and operator power. In addition, the performance of the power sprayer was compared with that of a knapsack sprayer. Based on the results, the average flow rate was 0.008874 L/s; average droplet size from the power sprayer was 0.3611 mm; average operator walking speed was 0.0413 m/s; average theoretical field capacity was 0.076764 ha/h; average effective field capacity was 0.058789 ha/h; average wind speed was 1.22 km/h; and average operator power was 0.227 kW. The average spraying efficiency of the power sprayer and knapsack sprayer was 76.66% and 60.66%, respectively. These findings indicate that the power sprayer is more efficient than the knapsack sprayer, as it requires less time, less physical effort, and delivers a comparable spray output. Furthermore, the power required by the operator when using the power sprayer is lower than that of the knapsack sprayer.
