ESUPPLIER APPROVAL PROCESS ON COMPOSITES’ PRODUCT-BASED MANUFACTURERS

The supplier is one of the keys to success in an organization and can also be the cause of the collapse of the company in which the supplier is able to introduce a number of problems such as supply of poor raw materials, shipping delays, poor services and failure to comply the requirement. Hence, approved supplier list has been used as a reference and a guide to the purchasing department to sourcing a trusted supplier. Therefore the development of process flow for approved supplier list must be done right for the effectiveness of this system. This paper analyzed supplier approval process on four selected companies specializing in composite product and manufacturing. The data collection consists of a series of semi-structured interview with supply chain personnel, documentation review and observation. These findings indicated that the same concept such as system audit, questionnaire and supplier assessment was used in a process of selecting potential suppliers prior to being inserted in the approved supplier list. Besides, the study identified that different companies (same business nature, but different product) had their distinctive ways in developing the process flow of the approved supplier list. The results can be used as reference to other companies to restructure their process flow for approved supplier list; focusing on their business goal and objective

Performance of Various Length-to-Diameter Ratio of Thermal Energy Storage Tank: A Convergence Test

Thermal Energy Storage (TES) is a technique that stores thermal energy, accomplished by changing the temperature of a storage medium, such as a phase change material (PCM), for later use in various applications, for example, heating and cooling or power generation. The heat energy that is saved is usually kept in the storage medium. This study investigates how the performance of the TES tank is affected by the ratio of length to diameter. The research focuses on how the ratio affects the convergence test while the PCM0 (water-ice) used in TES starts to release latent heat into the air. Five models were designed by using CATIA software and the analysis was conducted in ANSYS CFD software. Convergence tests were conducted to validate the accuracy of the obtained simulation results. Two additional criteria, namely temperature and ice mass fraction, were also analysed to evaluate the performance of the TES tanks. The investigation of the TES tank using five different models has shown that each model reaches a constant temperature of 0°C during the melting phase, but at different time intervals. Model 1 reaches this temperature the fastest, followed by Model 2, Model 3, Model 4, and finally Model 5. A model that reached the constant temperature first indicated a more efficient discharging process, as it signified a faster rate of ice melting and thermal energy release. In terms of ice mass fraction, Model 1 retained a significant amount of solid ice (0.9968), with noticeable melting. Model 5, on the other hand, showed minimal melting and better preservation of solid ice (0.9992). Considering temperature, ice mass fraction and ease of convergence, Model 1 performed the best, when the solidified PCM0 was melting faster while maintaining a substantial amount of solid ice in the TES tank. The present study was successfully developed and compared various TES configurations while satisfying the convergence criteria set in the simulation. To conclude with, the results showcase the performance differences based on pipe size. These discoveries contribute to refining tube-type TES tanks and their design for thermal energy storage systems

A New Design Optimization of Light Weight Front Lower Control Arm

In this paper, the design optimization and fabrication process of Aluminium cast for Lower Control Arm (LCA) were investigated. The aluminum lightweight front lower control arm will be developed using casting processing route and its performance will be investigated to determine the mechanical properties of the parts. In this work, the new concept design of cast lower arm are employed. Then, the topology optimization process is conducted to get the optimized shape based on target 20% weight reduction. The final optimized design is evaluated with structural strength analysis to analyze component performance in a vehicle. The parts that produced is expected to have a lightweight, high strength and good corrosion resistance and suitable for  current vehicle performance

Muslim Friend7 Ly Tourism and Accommodation of Malaysian Hotel Industries

Malaysia is one of the countries that attract tourist from all over the world. There is no barrier for the tourist to select from a range of halal products and hotel services available. Therefore, several potential attributes of Muslim friendly hotel services were analyzed from two major tourist destination state of Malaysia, namely Kedah and Penang. The analysis was based on three major online accommodation service providers. The findings revealed the significant information of the Muslim friendly hotel services in Malaysia. Therefore, updating the current information of the Muslim friendly tourism services is recommended.Malasia es uno de los países que atrae a turistas de todo el mundo. No hay ninguna barrera para que el turista seleccione entre una gama de productos halal y servicios de hotel disponibles. Por lo tanto, se analizaron varios atributos potenciales de servicios hoteleros amigables para los musulmanes en dos de los principales destinos turísticos de Malasia, a saber, Kedah y Penang. El análisis se basó en tres proveedores principales de servicios de alojamiento en línea. Los hallazgos revelaron la importante información de los servicios de hotel musulmanes amigables en Malasia. Por lo tanto, se recomienda actualizar la información de los servicios turísticos musulmanes amigables

A systematic review of studies examining the relationship between resilience and physical asset management for water system

The resilience in the water system can produce great benefits; one of the ideal ways to achieve resilience is through asset management. The purpose of this study is to systematically review the literature that presents the relationship between asset management and resilience. We searched multiple databases such as Emerald Insight, Sage Publication, Science Direct, Scopus, Taylor and Francis, and Wiley Online Library ranging from the year 2000 until the year 2020. The papers are written in English. A total of 7845 articles have been successfully identified and only 6 papers met the inclusion criteria of the study. The study has concluded that most of the previous research that discusses asset management and resilience are in groups dating 5 years back (2015-2019). Several features of physical asset management require further investigation that can enhance the resilience of the water system. The topic is relatively new and hopes to open a huge gap for research

Factors Affecting the Performance of Double Chamber Microbial Fuel Cell for Simultaneous Wastewater Treatment and Power Generation

Electricity generation from the readily biodegradable organic substrate (glucose) accompanied by decolorization of azo dye was investigated using a two-chamber microbial fuel cell (MFC). Batch experiments were conducted to study the effect of dye and substrate concentration on MFC performance. Electricity generation was not signifi cantly affected by the azo dye at 300 mg/L, while higher concentrations inhibited electricity generation. The chemical oxygen demand (COD) removal and decolorization of dye containing wastewater used in the MFC were studied at optimum operation conditions in anode and cathode, 57% COD removal and 70% dye removal were achieved. This study also demonstrated the effect of different catholyte solutions, such as KMnO4 and K2Cr2O7 on electricity generation. As a result, KMnO4 solution showed the maximum electricity generation due to its higher standard reduction potential
