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

 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.

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.
