Abstract

The palm oil processing industry is expanding rapidly, as seen from the increasing land conversion for oil palm plantations. One critical machine in the production process is the sludge centrifuge separator, which functions to separate oil from sludge. At PT. X, a breakdown in this machine disrupted production and reduced the effectiveness of oil separation. This study aims to identify the causes of damage or failure in the sludge centrifuge separator machine. The research employs Root Cause Analysis (RCA) with a fishbone diagram as the analytical tool and proposes improvements using the 5W+1H approach.The results show that damage is caused by several factors. Human factors include operator negligence, lack of discipline, and inadequate supervision. Machine-related issues involve poor maintenance, leaks, insufficient inspections, bearing wear, and excessive friction. Material factors include the entry of metal pieces and small stones into the machine. Method-related problems stem from non-compliance with SOPs and insufficient training. Environmental factors include damp conditions, poor air circulation, oil spills, noise, and an unclean production floor.This research highlights the importance of regular maintenance, improved training, strict SOP implementation, and better workplace management to minimize machine failure and ensure optimal.

Abstract

Security risks cover all aspects, including users usually feel lost or there is a leak of personal data, so there are often complaints by users who feel dissatisfied with a company. Risk management of information security is a methodology to identify and assess security risks by implementing, controlling and handling risks to protect an organization's interests. This research examines the bibliometric characteristics and trends of articles on “Risk of Information Security Management System”. Data from the Scopus database was collected, published between 1987 and 2023. Through searching the Scopus database, 1,351 articles were found. Bibliometric analysis was conducted using the vosviewer tool to visualize the research trends of this study. “Risk Management” and ‘Information Security Management Systems’ articles were found in 165 institutions and 87 countries. The bibliometric analysis revealed that Norges Teknisk-Naturvitenskapelige University had the most “Risk Management” and “Information Security Management Systems” research publications, with a total of 28 documents.
