Abstract

General Background: Workload measurement is a critical component in manufacturing management to ensure balanced labor allocation and cost control. Specific Background: PT. XYZ, a wooden board manufacturing company, faces high production targets requiring operators to maintain consistent productivity without additional staffing. Knowledge Gap: Although workload analysis is commonly applied to determine optimal workforce levels, limited studies explicitly connect workload measurement results with structured incentive determination in manufacturing settings. Aims: This study aims to calculate operator workload using the Workload Analysis (WLA) method and determine appropriate incentives based on workload exceeding normal capacity. Results: Work sampling revealed productive percentages of 78%–83%, and WLA calculations showed workload levels of 106%–115%, indicating overcapacity conditions. The excess workload ranged from 6% to 15%, forming the basis for incentive allocation proportional to overload levels. Novelty: This study integrates work sampling, allowance calculation based on ILO standards, and workload analysis to establish a quantitative linkage between workload percentage and incentive determination. Implications: The findings provide a managerial framework for incentive policy formulation without increasing the number of operators, supporting cost control while maintaining production targets in manufacturing operations. Keywords: Workload Analysis, Work Sampling, Operator Productivity, Incentive Determination, Manufacturing Operations Key Findings Highlights Operator capacity levels exceeded standard workload thresholds across all stations. Productive activity percentages ranged between seventy-eight and eighty-three percent. Incentive allocation was proportionally calculated from quantified overload values.

Abstract

Alkali treatment of natural fibers has a role in removing hemicellulose and lignin layers. This layer prevents the matrix from bonding with the natural fiber cellulose structure. The use of an inappropriate type of alkali will reduce its effectiveness and can even damage the cellulose layer. This study compared the effectiveness of alkaline NaOH, CaOH and KOH in removing lignin and hemicellulose and their ability to maintain cellulose content. The use of the immersion method in alkaline solutions is well controlled. The FTIR characterization test was used to detect functional group changes, the TGV test to detect heat resistance ability, the XRD test to detect structural changes in crystalline and amorphous properties of sansevieria natural fibers. Furthermore, the tensile test to determine the effect of alkaline treatment on changes in mechanical strength Tensile strength. From the test results it was found that the alkaline NaOH gave the best characteristics by detecting the presence of cellulose, tensile strength and the nature of the crystalline atomic structure. Highlights: Effectiveness of Alkali Types: Comparison of NaOH, CaOH, and KOH effectiveness in removing lignin and hemicellulose while preserving cellulose content. Characterization Techniques: FTIR, TGA, and XRD tests used for functional group changes, heat resistance, and structural properties evaluation. NaOH Superiority: Alkaline NaOH treatment demonstrated best results in maintaining cellulose, enhancing tensile strength, and influencing atomic structure. Keywords: Alkali treatment, Natural fibers, Lignin removal, Cellulose preservation, Tensile strength.

Abstract

General Background Work-related musculoskeletal disorders are often caused by non-ergonomic working postures in manual activities. Specific Background Fabric measuring and cutting processes are commonly performed in awkward positions such as bending and squatting, increasing ergonomic risk. Knowledge Gap However, limited studies evaluate these activities using combined RULA and NERPA assessment methods. Aims This study aims to analyze the working posture of operators in fabric measuring and cutting processes using RULA and NERPA methods. Results The findings show that the measuring activity obtains a RULA score of 6, indicating moderate risk, while the cutting activity reaches a score of 7, indicating high risk requiring immediate action. Using NERPA, both activities show a score of 6, indicating moderate risk requiring improvement. Novelty This study applies dual ergonomic assessment methods to identify risk levels in specific textile work activities. Implications The results support the need for ergonomic workstation design, including the proposed worktable, to reduce posture-related risks and improve worker safety. Keywords: Ergonomic Assessment, RULA Method, NERPA Method, Musculoskeletal Disorders, Work Posture Key Findings Highlights Cutting task shows highest risk classification Both techniques indicate need for corrective action Workstation redesign recommended to reduce strain

Abstract

General Background: Productivity and machine effectiveness are critical factors in manufacturing systems to ensure product quality and operational efficiency. Specific Background: In PVC pipe production, machine downtime and performance issues often reduce overall productivity levels. Knowledge Gap: Limited integration of Overall Equipment Effectiveness and Failure Mode and Effect Analysis is applied to identify root causes and prioritize improvements in machine performance. Aims: This study aims to evaluate machine productivity using OEE and determine improvement priorities using FMEA in a PVC pipe production process. Results: The analysis shows an average availability of 91%, performance rate of 80%, and quality rate of 93%, resulting in an OEE value of 68%, which is below the ideal standard of 85%. The main causes of low effectiveness are related to downtime factors such as pipe defects, machine instability, and operator-related issues. FMEA analysis identifies priority improvements with the highest Risk Priority Number of 648, followed by 392 and 378. Novelty: The study combines OEE and FMEA to provide a structured evaluation of machine productivity and prioritized corrective actions. Implications: The findings offer practical guidance for improving machine performance and reducing downtime in manufacturing operations. Keywords: Machine Productivity, OEE Analysis, FMEA Method, Downtime Factors, Manufacturing System Key Findings Highlights Combined metrics revealed suboptimal operational performance below standard threshold Root cause mapping identified dominant sources of production interruption Risk prioritization guided targeted corrective action planning

Abstract

PT SPLN merupakan salah satu perusahaan penanaman modal dalam negeri yang bergerak di bidang industri panel listrik, variable air volume, fire damper, dan diffuser. Pada saat volume pemesanan meningkat, perusahaan menerapkan kebijakan overtime atau penambahan jam kerja bagi karyawan. Hal tersebut berdampak pada menurunnya tingkat kehadiran karyawan di hari berikutnya sebesar 20%, yakni sekitar 3-5 pekerja dari total 18 orang. Selain memengaruhi kehadiran, kebijakan overtime juga memicu kelelahan fisik maupun mental pada pekerja. Penelitian ini bertujuan untuk mengukur besarnya beban fisik serta mental yang dirasakan oleh karyawan, sekaligus mengidentifikasi faktor-faktor yang memengaruhinya. Beban kerja mental diukur menggunakan metode NASA-TLX, sedangkan beban fisik diukur dengan metode analisis beban kardiovaskular (Cardiovascular Load atau CVL). Hasil penelitian menunjukkan bahwa kelelahan fisik (CVL) ditemukan pada hampir seluruh operator produksi dengan tingkat di atas 30%. Sementara itu, metode NASA-TLX mengindikasikan bahwa faktor performansi memiliki dampak paling besar dalam memengaruhi beban kerja karyawan, yaitu sebesar 44,79%.
