    A study of new washing process which combines deflection and abrasion action
    This study aimed to determine the optimum washing of laboratory washing model that design to stimulate the active washing process and passive commercial washing machine are compared in order to determine the best washing result. Variables of the study include water speed, washing time and radial nozzle inclination angle. The rotational system of an automatic washing machine has two major technical difficulties. One is the collision of the tub against the frame at the beginning of its early spinning stage. A factor that causes such instability of the rotational object can be attributed to the deflection of the liquid inside the liquid balancer due to the unbalance mass. Proposed a new washing technology and new design of the washing machine can be as a base of its new type. These machines have better outcome data; improve quality of washing process and effective use of washing liquid. New washing machine is simple design, does not have rotary parts at all and uses active process of washing process with squeezing of linens and more productive then known washing machines. Also, this machine can recycle and feed cleaned washing liquid. Additionally, in use of ultrasonic technology of washing process, new machine today will be perfect design.

    Non flow process ultra high temperature (UHT) boiler application to dadih processes
    The 'dadih' and milk factory is kind of a small factory and it is called as SME (Small and Medium Enterprise). The purpose of visiting to these factories is to find out the main problem faced by the factories currently. Through a series of analysis such as questionnaire, interview and also observation, the problems are found. According to the factories visited, the cooking method by the factories are varies. Some of the factories are using the traditional method which is cooking by using gas stove and some are using semi-automated boiler. However, the boiling point of the traditional cooking method is around 100°C and it is not able to kill the milk spores in the milk products. A high temperature (135°C-150°C) to cook the milk products in short time (3s-5s) is the basic requirement to kill the milk spores in the milk products. The milk spores are the main reason to shorten the life span of the milk products. According to the information provided by the factory, the life span of 'dadih' produced by using the traditional method are very short which is maximum 2 or 3 weeks if it is refrigerated. In other words, if the products are placed in a normal room temperature, it will not last more than 4 hours. The problem is those factories are intended to buy a UHT boiler but the existing boiler in the market is too big and too expensive which is not suitable and affordable by Small and Medium size (SME) companies.

    Optimization parameter effects on the quality surface finish of the three-dimensional printing (3D-printing) fused deposition modeling (FDM) using RSM
    Fused Deposition Modeling (FDM) is an additive manufacturing technology which is used to print the 3D (Three-Dimensional) object. It has relatively low surface qualities that will affect the performance of the printed part. Thus, this research has been done to analyze the selected parameter effect on the quality surface finish of the 3D printing objects and find the optimum response of processing parameters using Response Surface Methodology (RSM). In order to predict the surface roughness, three parameters have been chosen which are layer thickness, print speed and fill density. The relations among responses and process parameters are determined and their validity is proved using Analysis of Variance (ANOVA). Then, the response surface plots are analyzed to establish main factor effects and their interaction on responses. The confirmation experiment has been carried out with the response optimizer to get the optimum parameter of the surface finish quality. Based on the results obtained, the surface roughness is mainly affected by the layer thickness compared to the fill density and print speed.

    The mold-making industry is currently facing several challenges, including new competitors in the market as well as the increasing demand for a low volume of precision moldings. The purpose of this research is to appraise a new formulation of Metal Epoxy Composite (MEC) materials as a mold insert. The fabrication of mold inserts using MEC provided commercial opportunities and an alternative rapid tooling method for injection molding application. It is hypothesized that the addition of filler particles such as brass and copper powders would be able to further increase mold performance such as compression strength and thermal properties, which are essential in the production of plastic parts for the new product development. This study involved four phases, which are epoxy matrix design, material properties characterization, mold design, and finally the fabrication of the mold insert. Epoxy resins filled with brass (EB) and copper (EC) powders were mixed separately into 10 wt% until 30 wt% of the mass composition ratio. Control factors such as degassing time, curing temperature, and mixing time to increase physical and mechanical properties were optimized using the Response Surface Method (RSM). The study provided optimum parameters for mixing epoxy resin with fillers, where the degassing time was found to be the critical factor with 35.91%, followed by curing temperature with 3.53% and mixing time with 2.08%. The mold inserts were fabricated for EB and EC at 30 wt% based on the optimization outcome from RSM and statistical ANOVA results. It was also revealed that the EC mold insert offers better cycle time compared to EB mold insert material.
