Abstract

The development of starch-based bioplastics is an innovative strategy for diversifying petrochemical industry products toward bio-based materials while simultaneously contributing to reducing the accumulation of persistent conventional plastic waste in the environment. Furthermore, the development can enhance the utilization of biological resources and agro-industrial waste more sustainably within a circular economy framework. However, starch-based bioplastics generally have weaknesses in mechanical properties and swelling capability. This study aims to synthesize starch-based bioplastics by modifying the type of filler and strach to improve physical, mechanical, and stability characteristics. The synthesis is carried out by mixing and gelatinizing starch with the addition of sorbitol as plasticizer with several types of starch and filler with certain compositions. Characterization is carried out on mechanical and physical properties. In addition, swelling capacity test and biodegradability test are conducted. The results showed that variations in types of starch and fillers affect the characteristics of the resulting bioplastics and optimization is needed so that the resulting material has the potential to be applied to environmentally friendly and sustainable packaging materials.

Abstract

The Cleaning In Place (CIP) process on Line 1 plays an important role in maintaining equipment cleanliness and ensuring product safety. However, excessive Cleaning Downtime increases production Downtime and Sodium Hydroxide (NaOH) consumption. This study aims to identify waste in the CIP process, determine the main causes of excessive Cleaning Downtime, and develop and implement improvement Actions to enhance Cleaning effectiveness. The methods used include Value Stream Mapping (VSM), Fishbone Diagram, Failure Mode and Effects Analysis (FMEA), and 5W1H. VSM results indicated that Cleaning Activities were classified as Non-Value-Added (NVA) Activities and significantly contributed to Downtime. FMEA identified the main causes of excessive Cleaning Downtime as the absence of nozzle valve covers (RPN=512), elevated machine positions that hinder inspections (RPN=448), insufficient awareness briefings (RPN=392), CIP frequency based on routine prActices (RPN=294), and the absence of NaOH usage records (RPN=252). Improvement Actions were developed using the 5W1H method and implemented through the installation of nozzle valve covers, CIP effectiveness verification, team awareness briefings, revision of the CIP matrix frequency, and NaOH usage monitoring. The implementation results showed that Cleaning frequency decreased from two times to one time per month, Cleaning Downtime decreased from 45.33 hours to 22.67 hours per month, and NaOH consumption decreased from 300 kg to 150 kg per month. These improvements successfully enhanced Cleaning effectiveness and chemical usage efficiency.

Abstract

The sanitary ware industry requires stable production processes because defects in ceramic products are critical and difficult to repair. PT RII experienced quality problems in the BN 150 G squat toilet product manufactured using the High Pressure Casting Machine (HPCM) process. Initial data indicated a defect rate of 8.55%, exceeding the company tolerance limit of 4%. This study aims to measure process capability, identify the main causes of crack defects, determine failure risk priorities, and establish the optimum air pressure parameter to reduce defects. The study employed the Six Sigma method with the Define, Measure, Analyze, Improve, and Control (DMAIC) approach integrated with Failure Mode and Effect Analysis (FMEA) and Design of Experiment (DOE). The results showed that the initial process condition had a Defects Per Million Opportunities (DPMO) value of 21,400 with a sigma level of 3.52. FMEA analysis identified unstable air pressure as the most critical cause of defects, with the highest Risk Priority Number (RPN) of 576. DOE results indicated that an air pressure of 3 bar produced the lowest defect proportion and had a significant effect on product defect status (p-value = 0.041). After improvement, the DPMO decreased to 17,000 and the sigma level increased to 3.62. These findings demonstrate that the integration of Six Sigma, FMEA, and DOE is effective in reducing crack defects and improving HPCM process capability in the sanitary ware industry.

Abstract

PT Kimindo Jaya Indonesia is an electrical panel manufacturing company that applies a Make-to-Order production system. One of the main problems faced by the company is material delay in Sub Distribution Panel (SDP) production, because several critical components are not available according to the assembly schedule. This study aims to develop an integrated Material Requirement Planning and Just-in-Time (MRP-JIT) material planning model to minimize delay risk in SDP panel production. This research used a descriptive quantitative approach with production data from January to June 2025. The data included production quantity, Bill of Materials, initial inventory, safety stock, scheduled receipts, supplier lead time, assembly schedule, and historical material delay data. Data processing was conducted through gross requirement calculation, net requirement calculation, Lot-for-Lot sizing, planned order receipt, planned order release, and JIT-based material arrival synchronization. The actual condition showed 10 material delay cases, with a total delay of 43 days and an average delay of 4.3 days per case. The proposed model scheduled material orders based on supplier lead time and targeted material arrivals one to two days before assembly. The results indicate that the MRP-JIT model can support the shift from reactive purchasing to preventive material planning.

Abstract

Inventory is an important asset that supports the continuity of production processes in manufacturing companies. One of the common problems is the discrepancy between physical inventory and system records during stock opname activities, which may cause financial losses and reduce inventory accuracy. This study aims to identify the causes of stock opname discrepancies and improve inventory accuracy of Local Parts materials at PT Inoi Mobile Indonesia (IMI). The methods applied in this research include Failure Mode and Effect Analysis (FMEA), Cycle Counting Method Method (CCM) with ABC classification, and Fault Tree Analysis (FTA) based on the 5W+1H approach. Data were collected through observation, interviews, and company stock opname records. The results indicate that the main causes of inventory discrepancies are recording errors, operator negligence, and weak implementation of standard procedures. FMEA analysis shows that non-real-time material issuing has the highest Risk Priority Number (RPN), making it the primary improvement priority. ABC analysis reveals that category A materials contribute the highest cost impact on the company. Furthermore, FTA systematically identifies the root causes of stock discrepancies. The integration of these methods is proven to improve inventory accuracy and effectively reduce stock opname discrepancies.
