Kasongan Ceramic UKM Center is an association of UKM which makes goods made from clay. Kasongan Ceramic UKM Center, located in Bantul Regency, DIY. The problem that is often experienced by Kasongan Ceramics Center is that products that are often cracked, warped, and easily brittle. The total production of Kasongan UKM Center from September 2019 to February 2020 was 32,256 units, with the number of defective products amounting to 3,873 or 12% of the total production. Based on the studies that have been done, it can be concluded that the defects of cracks, curling, and brittleness that occur are one of them caused by the less than optimal flexural strength of the ceramic products produced. To maximize the flexural strength of the ceramic products produced, the optimal ceramic manufacturing process parameters will be determined using the Taguchi method. To maximize the flexural strength in the process of making ceramics using the Taguchi method, it is necessary to do an experimental design. The first thing to do is to determine the controlled factors and levels in the ceramic manufacturing process that affect the flexural strength. After that determine a suitable orthogonal array and perform experiments based on the specified orthogonal array. The experimental results will be tested for its flexural strength in the laboratory. The resulting flexural strength data will be processed to determine the optimal ceramic manufacturing process parameters that maximize the bending strength of ceramics. Based on the data processing carried out, it is found that the optimal ceramic-making process parameters at the Kasongan Ceramics UKM Center that maximize flexural strength are the composition of 3 parts Godean clay, 3 parts Kasongan clay composition, 1 part sand composition, and burning using an open tub.

A vantagem do processo de fabricação de tijolos com manipueira é ser ecologicamente correto, pois não consome água, nem há necessidade de ir ao forno, economizando recursos naturais e fazendo uso de um efluente altamente poluente. Assim, este trabalho objetivou analisar as propriedades mecânicas de tijolos fabricados com solo associado à manipueira como alternativa sustentável. Foram avaliados os parâmetros absorção de água e resistência à flexão. Em conformidade com os resultados, observou-se que as massas cerâmicas apresentaram valores de absorção de água da ordem de 10 a 13 %, valores aceitáveis para fabricação de blocos cerâmicos e valores de resistência a flexão adequados para fabricação de tijolos maciços, tanto, os corpos de prova com queima quanto os corpos de provas sem queima. Assim, conclui-se que a troca da água pela adição da manipueira na massa cerâmica não interfere nas propriedades mecânicas e esta pode ser adicionada a massa cerâmica para fabricação de tijolos ecológicos através do processo de prensagem.Mechanical properties of manufactured bricks with soil and cassava wastewaterAbstract: The advantage of the manufacturing process of brick with cassava is being environmentally friendly because it does not consume water, and there is no need to go to the oven, saving natural resources and making use of a highly polluting effluent. This work aimed to analyze the mechanical properties of bricks made from soil associated with cassava as a sustainable alternative. Parameters were evaluated water absorption and flexural strength. In accordance with the results, it was observed that the ceramic material provided water absorption values of the order of 10 to 13%, acceptable values for manufacturing ceramic blocks and bending strength values suitable for manufacture of solid bricks, both proof bodies test with burns as the proof bodies of evidence without burning. It is therefore concluded that the replacement of water by the addition of cassava the ceramic mass does not interfere with the mechanical properties and that can be added to the ceramic paste for manufacturing green bricks through the pressing process.

In the present work, Taguchi method was employed to optimize tensile strength and hardness of the stir casted Al/RHA composite. The composites were prepared by varying stir casting parameters like stirring time (6, 9, 12 min), stirring speed (100,200,300 r.pm), and weight percentage of RHA reinforcement (6, 9, 12 %). All the experiments were conducted based on plan of experiments (L9 Orthogonal array) generated through Taguchi Technique. The individual influence of each process parameters on the hardness and tensile strength was determined by using analysis of variance. The result implies that the wt. % of RHA reinforcement was found to be a highly influenced parameter followed by stirring time and stirring speed. Finally, confirmation test was done to verify predictive model with the experimental results.

Polishing is a manufacturing process for surface-smoothing. To minimize surface damage and defects, gentle polishing conditions are required. The main objective of this research is to determine the effect of polishing conditions by using Taguchi method , and to optimize the process parameters to obtain the best surface possible. The experimental results indicate that a set of optimal polishing conditions for producing work surface within the range of parameters evaluated, double oblique polishing path, relatively high speed and low feed rate are desirable for improve surface.

In this research, orthogonal array of L27 in Taguchi Method was used to optimize the process parameters (control factors) variation in 45nm n-channel device with considering the interaction effect. The signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to study the performance characteristics of the device. There are only five process parameters (control factors) were varied for 3 levels to performed 27 experiments. Whereas, the two noise factors were varied for 2 levels to get four readings of Vth for every row of experiment. In this study, nominal-the-best characteristic was used in an effort to minimize the variance of Vth. The results show that the Vth values have least variance and percent different from the target value (0.287V) for this device is 1.42% (0.293V). This value is closer with International Technology Roadmap for Semiconductor (ITRS) prediction.

Response Characteristics

Our dependency towards wood has reduced the number of forests especially in Indonesia. Hence, many people tried to use another material as a replacement of wood. One of them is composite. Department of Industrial Engineering Universitas Sebelas Maret has developed paper-based composite using newspaper waste in Praktikum Perancangan Teknik Industri (PPTI) II. Unfortunately, the quality of composite is not so good. This paper tried to understand the effect of factors to responses and discover the best combination of factors to obtain the best responses. The responses of this experiment are tensile strength, bending strength and impact value. The factors of this experiment are paper pulp, PVAc glue and water. Taguchi method is used to find the appropriate orthogonal array and Particle Swarm Optimization method to find the optimum combination of the factors. Orthogonal array used in this experiment is L9 (34).  Through analysis, all of the factors are significant to tensile and bending strength, but they are not significant to impact value. The best combination of factors is 175 grams paper pulp, 130 grams PVAc glue and 175 ml water. Optimum results obtained for tensile strength is 0.7595 N/mm2, bending strength is 4.873 N/mm2 and impact value is 0.0138 J/mm2.

Abrasive Water Jet Machining

In this paper, Taguchi method is applied to find optimum process parameter for Abrasive water jet machining (AWJM). Abrasive water jet machining is a non–traditional process of removal of material by impact erosion of high pressure, high velocity of water and entrained high velocity of grit abrasives on a work piece. Experimental investigation were conducted to assess the influence of abrasive water jet machining (AWJM) process parameters on MRR and surface Roughness (Ra) of aluminium. The approach was based on Taguchi’s method and analysis of variance (ANOVA) to optimize the AWJM process parameter for effective machining and to predict the optimal choice for each AWJM parameter such as pressure, standoff distance, Abrasive flow rate and Traverse rate. For each combination of orthogonal array we have conducted three experiments and with the help of ANOVA it is found that these parameters have a significant influence on machining characteristics such as metal removal rate (MRR) and surface roughness (SR). The analysis of the Taguchi method reveals that, in general the standoff distance significantly affects the MRR while, Abrasive flow rate affects the surface Roughness. Experiments are carried out using (L9) orthogonal array by varying pressure, sta
