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

Domestic wastewater, which is categorized into black water and grey water, is one of the main sources of water pollution due to its high concentrations of Total Suspended Solids (TSS) and Total Coliform, both of which negatively impact human health and the environment. This study aims to evaluate the effectiveness of Aloe vera as a biocoagulant in reducing TSS and Total Coliform concentrations in domestic wastewater from Housing Complex X, Sirnabaya Village, Karawang Regency, as well as to compare its performance in gel and liquid forms. The research method applied was a laboratory scale experiment using the jar test. Wastewater samples were collected through composite sampling at three different times in one day (08.00, 14.00, 20.00 WIB). The Aloe vera biocoagulant was processed in two forms: gel and liquid. Dosage variations tested were 0, 10, 15, 20, and 25 mL/L. The results showed that the Aloe vera biocoagulant was effective in reducing both TSS and Total Coliform. In the gel form, with the dose of 25 mL/L reached the result 86% for TSS  and 76% for Total Coliform, meanwhile for the liquid form reached the result 76% and 73% with 10 mL/L dose. The superior performance of the gel form compared to the liquid is attributed to its more intact active compounds, such as acemannan for TSS and anthraquinones for Total Coliform.
