Abstract

In the era of high market competition, product development must implement excellent innovation and responsiveness toward customer needs. One of the tools that had been successfully applied to support this objective is Kansei Engineering. Kansei is a Japanese word that refers to perception, impression, and feeling. Kansei Engineering is the process to collect product information based on the psychological emotions and feelings of customers. These represent customers' general impressions and emotions towards certain products or services which are then translated into characteristic designs. In this research, the researcher uses the Kansai engineering is applied to design new packaging for West Sumatra Sanjai Chips produced by local small-medium enterprise (SME). In processing the data, the researcher carried out a sampling technique, determining the number of respondents with the number of respondents being 100 in the first stage and 15 respondents in the second stage. From the first stage, eight Kansei words were collected. Followed by the second stage which was able to classify the most significant Kansei words based on the customer opinions. It was demonstrated from the investigation that new packaging was designed. With the new design it is expected that customers will become more aware and attracted to purchase the product.

Abstract

Many industries have been in demand for metal matrix composites (MMC), especially in the aerospace and automotive sectors. The advancement of MMC is being investigated to improve the material's mechanical properties. MMC is a composite material consisting of at least two materials. One of them would act as a matrix, and the other materials would serve as reinforcement. MMC allows for overcoming the specific limitations of metallic and ceramic materials by blending their mutually exclusive property profiles. The main objective of this research is to successfully fabricate aluminium and graphite metal matrix composites using powder metallurgy. In this research, powder metallurgy was used, where aluminium and graphite were blended according to the sample volume ratio. Both graphite and aluminium were in the form of metal powder. Graphite powder with each ratio of volume percentages of 0%, 1.5%, 3%, 4.5%, and 6% was mixed with aluminium powder. The blended material is produced by powder metallurgy via the compaction process using the hydraulic press brake machine. Subsequently, the compacted sample was sintered using a laboratory furnace at 600°C for 4 hours. The mechanical tests show that the highest tensile strength and Young's modulus were obtained by MMC aluminium – 1.5 % volume graphite. While for the highest hardness was achieved by aluminium – 4 % volume graphite.

Abstract

The initial survey has been conducted by our team in the Acrylic Craft Thematic Village Gunung Pangilun, Padang City, which we abbreviate as “Kampung Akrilik”. From interviews with local artisans, our team realized that the marketing of SME products in this village has not been fully optimized, primarily due to a lack of product variety offered. Faced with this issue, our team felt challenged to contribute by helping direct the artisans to focus on developing products that align with the needs and preferences of potential buyers. Furthermore, we also identified the necessary raw materials and equipment required to create the previously identified new products. Once the new products were identified, the next step was to organize a socialization event. This socialization includes the techniques for creating the new products, such as 3D printing. Through this Community Service project, we hope to revitalize productivity in Acrylic Village. We aim to assist the local community in increasing their product sales and achieving an overall improvement in sales volume.
