Abstract

Maintenance of the ship is a task aimed at ensuring that the ship continues to operate in a normal and seaworthy condition. This work is related to the ship's machinery system and other equipment on board. If the ship does not receive regular maintenance, it can impact the condition and performance of the ship. By implementing Reliability Centered Maintenance (RCM), information about the steps needed to ensure optimal operation of the engine or equipment can be obtained. RCM is a method used to develop Preventive Maintenance. In Time Directed (TD), there are two components, namely the schottel Asd component and the valve on the cylinder head. In Condition Directed (CD), there are three components found in the three pipe components: fuel pipe, oil, and engine coolant. In Failure Finding (FF), there are four components found in the seachast component, injector pump, fuel filter, and air. Based on the application of the RCM method used, the recommended maintenance actions for the Finding Failure (FF) category include daily, weekly, and monthly inspection activities. Meanwhile, for the Time Directed (TD) category, maintenance actions involve scheduling component replacements based on predetermined intervals. Keywords: FMEA, LTA, Maintenance, RCM

Abstract

Efficient inventory management is essential for facilitating seamless manufacturing at PT ZYX, especially in managing child part stocks from several vendors. Suboptimal inventory management may result in stock deficits or surpluses, affecting production continuity and operational expenses. This study seeks to evaluate kid part inventory according to its strategic significance and establish safety stock levels for category A goods. The ABC classification approach was utilized to categorize inventory according to significance, and safety stock analysis was performed to determine ideal stock levels for essential items. The findings reveal that among 35 child components, 8 things are classified as category A, 4 items as category B, and 23 items as category C. The maximum safety stock value was identified in child component ID 70025 at 2,891 pieces, whilst the minimum was recorded for ID 70002 at 248 pieces. These findings offer a systematic inventory management strategy that enables the organization to enhance stock control, reduce expenses, and increase operational efficiency. The adoption of ABC categorization and safety stock analysis is anticipated to improve inventory management, facilitating a more efficient supply chain and superior resource allocation.

Abstract

 The need for clean and safe drinking water is increasing, so innovative disinfection methods are needed. This study evaluates the effectiveness of Polysilicone coated with Chitosan-Nanosilver (PCAg) as a disinfectant for drinking water treatment. The synthesis process involves the reduction of silver nitrate (AgNO3) with sodium citrate, which is then combined with chitosan in an acetic acid solution to produce a stable mixture of nanoparticles. This solution was then impregnated into polysilicone foam to create a functional filter media. The experimental results showed that the PCAg were able to effectively remove bacterial contaminants, including Escherichia coli and Total Coliform, from the distilled drinking water samples from 4 CFU/100mL to 0 CFU/100 mL, as per the quality standard of the Ministry of Health of the Republic of Indonesia number 2 of 2023. Analysis of the SEM-EDX characterization method showed an evenly distributed Chitosan-Nanosilver coating on the polysilicone surface, evidenced by the detection of 1.31% Nanosilver and an increase in carbon percentage from 40.16% to 44.98%. In addition, analysis of the FTIR characterization method showed the presence of peaks indicating alkane vibrations, aromatic rings, ester groups, and amine groups typical of chitosan. This indicates that chitosan has been coated on polysilicone. This study concludes that the coating process enables optimal interaction between chitosan, silver nanoparticles, and polysilicone, thus enhancing the antibacterial properties of the material. Thus having a significant ability to eliminate bacteria.

Abstract

Human life is inseparable from the use of plastic in everyday life. LDPE plastic significantly impacts the environment as it is difficult to decompose naturally. On the other hand, natural waste such as seashells and coconut fiber are often found without further processing needs to recycle. To overcome this issue, there must be an effort to recycle these wastes. This research aims to determine the substitution effects of recycled products (LDPE plastic, seashells, coconut fiber) in producing paving blocks. The paving block is made with 2 main variations: a mixture of LDPE plastic and seashells (X1 and X2) and a mixture of LDPE plastic and coconut fiber (Y1 and Y2). The results show that paving block X has a higher compressive strength than paving block Y. The best paving block mixture is variation X2, which has a maximum load of 11 kN, a compressive strength of 46.797 kgf/cm2, and a maximum water absorption capacity of 4,8 %. The compressive strength values from the variations of the produced paving blocks are below the quality requirements set by SNI03-060292-1996. However, producing paving blocks with LDPE plastic, seashells, and coconut fiber can positively address waste issues in the Karawang Regency community through recycling practices.

Abstract

PT XYZ is a company operating in the food industry. The company produces various kinds of food, such as biscuits, wafers, vermicelli and noodles. Noodle products are the most popular products, and there are often significant changes in each period. This causes fluctuations and results in uncontrolled inventory. PT XYZ can avoid this problem if it has a way to estimate noodle demand. Forecasting is a planning method for estimating products in the future. The moving average and linear regression methods are the methods used in this research. Based on the results of the calculations carried out, the method chosen is the linear regression method because the smallest Mean Squared Error (MSE) value is 620370900 and the tracking signal results from the linear regression method are close to zero. The results of forecasting the need for noodle products for the next period were 169,524 pcs. It is hoped that the results of this forecasting can help PT XYZ in carrying out production planning.
