Abstract

Rapid technological advances lead to intense business competition among entrepreneurs. Entrepreneurs utilize technology to improve company performance and profits. Many companies have begun implementing information systems to ensure their operations run smoothly. The transition to information systems or digitalization faces a number of challenges for employees, resulting in decreased performance due to difficulty in adapting. This problem also occurs in the supply chain division, which is one of the main parts of the company's operational management. This study aims to analyze the impact of information systems on the performance of the supply chain division. The study was conducted quantitatively using the Multiple Linear Regression method. The Multiple Linear Regression method involves more than one independent variable. Sampling was carried out by distributing questionnaires to 50 employees of the supply chain division. The results of the SPSS test of multiple linear regression show that the regression coefficient values ​​for the variables of ease of use of information systems, availability and quality of real-time data, and the level of automation and process efficiency, have positive values. This means that if the value of the three variables increases, the performance of the supply chain division will increase. These three variables need to be further considered by the company in handling the digitalization process.

Abstract

This article summarizes an independent internship project conducted at PT XYZ during September–December 2025 within the HSSE (Health, Safety, Security, and Environment) function. The focus was evaluating the implementation of ISO 9001:2015 and the International Ship and Port Facility Security (ISPS) Code in the port facility access control procedure, especially at the main gate and restricted areas. Data were collected through on-site observation, document review of access control SOPs, inspection forms, and risk records (HIRADC), and discussions with security, HSSE, and operational personnel. The analysis applied process mapping, risk-based thinking, HIRADC, and gap analysis to compare field practices with standard requirements. Results indicate that access control is implemented through layered controls: identity and permit verification, RFID-based access restrictions, CCTV monitoring, system logging (e.g., CTOS), and routine inspections. Key risks such as unauthorized access, human error during goods checks, and night-shift fatigue are mitigated by administrative controls, supervision, and shift management. Practical issues were found in reporting format differences and mismatches between field conditions and administrative records, requiring periodic verification and data standardization to strengthen audit readiness and continual improvement.

Abstract

General Background: Quality risk mitigation is essential for maintaining production stability and product conformity in manufacturing industries. Specific Background: PT XYZ produces High Density Polyethylene plastic bags in various sizes, with the 15×30 size exhibiting the highest defect rate during January–September 2025, particularly folded, incorrect cutting, asymmetrical cut, and no handle hole defects. Knowledge Gap: Previous studies generally applied Fault Tree Analysis (FTA) or Failure Mode and Effect Analysis (FMEA) separately or focused on limited defect types and specific production stages, resulting in less comprehensive defect evaluation. Aims: This study aims to systematically identify root causes and determine improvement priorities for dominant defects in 15×30 HDPE plastic bag production through an integrated FTA and FMEA framework. Results: FTA identified 15 critical basic events associated with operator control, machine condition, material handling, and maintenance practices. Defect probability values were 7.079% for folded, 9.314% for incorrect cutting, 9.741% for asymmetrical cut, and 6.635% for no handle hole defects. FMEA results showed the highest Risk Priority Number for folded defects (RPN 240), followed by incorrect cutting (RPN 210), asymmetrical cut (RPN 180), and no handle hole (RPN 175). Novelty: The study integrates deductive root cause modeling and quantitative risk prioritization within a single analytical structure applied to a specific industrial product size. Implications: The proposed actions, including SOP standardization, preventive maintenance, calibration, and operator monitoring, provide structured guidance for systematic defect reduction and sustainable quality management in HDPE plastic bag manufacturing. Highlights: Fifteen critical basic events were mapped across operator, machine, material, and maintenance factors. Incorrect cutting and asymmetrical cut showed the largest probability values among dominant nonconformities. Risk prioritization placed folded nonconformity at the top improvement rank based on RPN assessment. Keywords: Fault Tree Analysis, Failure Mode and Effect Analysis, HDPE Plastic Bags, Defect Probability, Risk Priority Number

Abstract

General Background: Production inefficiencies in pharmaceutical manufacturing are frequently associated with process waste and packaging defects that reduce operational performance and product quality. Specific Background: In herbal oil production, the outer packaging stage exhibited recurring defects, motion waste, and overprocessing activities that increased lead time and generated non-value-added activities. Knowledge Gap: Previous studies on Lean, Six Sigma, and Lean Six Sigma have predominantly focused on general manufacturing industries and rarely integrated Value Stream Mapping, VALSAT, Fishbone Diagram, and Failure Mode and Effect Analysis within a comprehensive DMAIC framework for pharmaceutical herbal packaging processes. Aims: This study aims to identify dominant waste types, analyze the root causes of packaging defects, and formulate improvement recommendations using an integrated Lean Six Sigma DMAIC approach. Results: The findings indicate that the dominant wastes were defect, motion, and overprocessing. The major packaging defects consisted of wrinkled labels, untidy individual bottle wrapping, and perforated group packaging, with untidy individual bottle wrapping showing the highest Risk Priority Number of 294. The proposed improvements eliminated non-value-added activities and reduced necessary non-value-added activities, decreasing production lead time from 7,497.4 minutes to 5,382.4 minutes while increasing Process Cycle Efficiency from 26.89% to 37.46%. The process achieved a sigma level of 3.59 with an average DPMO of 18,016. Novelty: This study integrates Lean Six Sigma DMAIC with VSM, VALSAT, PAM, Fishbone Diagram, and FMEA to provide a structured risk-based evaluation of waste and defects in herbal oil packaging operations. Implications: The results demonstrate that systematic waste reduction and defect mitigation support higher production efficiency and operational performance in pharmaceutical manufacturing. Highlights: Defect, motion, and overprocessing emerged as the dominant production waste categories. Risk evaluation identified untidy individual bottle wrapping as the highest-priority failure mode. Proposed process changes shortened manufacturing duration and raised Process Cycle Efficiency. Keywords: Lean Six Sigma, DMAIC, FMEA, Herbal Oil Packaging, Process Cycle Efficiency
