A STUDY ON THE ANALYSIS OF CAUSES OF WORK ACCIDENTS IN GRINDING WORKERS USING THE SYSTEMATIC CAUSE ANALYSIS TECHNIQUE (SCAT) METHOD IN SUBCONTRACT X, PT X, NORTH JAKARTA

Agus Joko Susanto, R.Ayu Anggraeni Dyah Purbasari
Abstract: Based on data from the HSE department at PT X, North Jakarta, from 2021 to 2024, the highest number of occupational accidents (KAK) occurred among grinding workers, totaling 12 cases. The types of accidents experienced by… y workers included metal sparks in the eyes, cuts, lacerations, scratches, and first-aid injuries. The purpose of this study is to analyze the causes of occupational accidents among grinding workers at PT X using the Systematic Cause Analysis Technique (SCAT) method. This research is a descriptive-analytic study using observation, interviews, and documentation studies. The research was conducted between July and August 2025. The research population consisted of 32 people, including 30 grinding workers who had experienced accidents, 1 HSE manager, and 1 field coordinator. The sample for this study is the same as the population. Data analysis used univariate analysis and the SCAT method analysis. Based on the results, the most frequent accident experienced by grinding workers was metal sparks in the eyes, involving 30 respondents (100%). The direct causes of these accidents were the use of inadequate PPE by 15 respondents (50%) and the improper use of grinding tools by 11 respondents (36.7%). It is recommended that management commit to maximizing the implementation of established K3 (Occupational Health and Safety) programs and standards so that work-related accidents can be prevented and zero accidents can be achieved.

A Study on the CTC Method Grinding Machine in Black Tea Processing at PTPN IV Unit Kebun Sidamanik

Ayub Januari Sidauruk, Winforstein Naibaho, Tambos Agust Sianturi
Abstract: Black tea processing Is categorized into two methods: (1” Orthodox and (2) CTC (Crushing, Tearing, and Curling). These methods are implemented through hands-on activities at the company/factory based on theoretical knowledge,… wledge, which is then applied in the form of field work practice (PKL). The conclusions drawn from the field work practice are as follows: The Sidamanik Plantation Is one of 24 tea plantations under the Sidamanik Plantation Unit of PTPN IV, located in Sidamanik ’istrict. The CTC black tea produced at the Sidamanik factory Is then shipped to the main factory for ’lending there, with the composition regulated by the technology department, as the CTC black tea from the Sidamanik factory does not yet have a s’les label. At the Sidamanik factory, grinding Is performed in two stages using a 15” Rotorvan” (RV) machine for the first grinding and a 36” Teaman CTC 4-Cut machine with four sets of sequential rollers for the second grinding. The Rotorvane’s capacity is 484,739.3533 kg of withered tea leav’s per hour, equivalent to 581,710.4923 ’g of fresh withred tea leaves per hour, and equivalent to ’21,810.1771 kg of dry tea per hour” The CTC plant’s capacity is 18,274.7704 kg of ground tea pe” hour, equivalent to a capacity of 21,930.6017 kg of fresh withered tea leaves per hour, and ”quiv’lent to a capacity of 4,592.2680 k” of dry tea per hour
