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

UMKM Pabrik Tahu AL merupakan salah satu produsen tahu yang beralamat di Kecamatan Kuranji, Kota Padang, Sumatera Barat. Secara umum permasalahan kurangnya persediaan bahan baku menduduki peringkat utama dalam permasalahan produksi pada Pabrik Tahu AL. Akibat dari kekurangan tersebut, terjadi kehilangan keuntungan yang diperoleh dan kadang pula terjadi kelebihan persediaan bahan baku sehingga menimbulkan biaya persediaan. Penelitian ini termasuk kedalam penelitian yang bersifat kuantitatif. Penelitian kuantitatif adalah metode penelitian yang mengumpulkan dan menganalisis data numerik untuk memahami fenomena dan menjawab pertanyaan penelitian. Pendekatan ini menggunakan pendekatan ilmiah dan berfokus pada pengukuran objektif dan analisis statistik. Penelitian kuantitatif mengumpulkan data antara lain data persediaan, data kelebihan dan kekurangan bahan baku tahu. Metode yang digunakan untuk pengolahan data yaitu metode Silver-Meal Heuristic. Dari hasil pengolahan data diperoleh hasil bahwa metode ini menghasilkan total biaya persediaan bahan baku yang lebih kecil dari pada total biaya persediaan yang diterapkan oleh Home industry Pabrik Tahu AL selama ini, Berdasarkan data dari bulan Januari 2020 sampai Desember 2021, dari kedua metode pengendalian persediaan bahan baku dapat disimpulkan bahwa metode Silver-Meal Heuristic lebih efisien siap apabila dibandingkan dengan metode Riil home industry dengan tingkat efisiensi sebesar 5,42 persen.
