Abstract

The composites materials are known for their flexibility due to the combinations of two or three different materials and manipulation of their compositions. The advantage offered by composite materials make it suitable for biomedical applications especially to be used for implants. There are three types of composites biocompatible materials namely Metal Matrix Composite (MMC), Ceramic Matrix Composite (CMC) and Polymer Matrix Composite (PMC). In order to produce the biocompatible composite materials, various manufacturing processes can be performed. The manufacturing processes of MMCs are stir casting and powder metallurgy; the typical manufacturing process for CMCs is powder metallurgy; and 3-D printing by synthesizing and cross-linking the networks is used for fabricating PMCs. One of the promising biocompatible composites is Hydroxyapatite Mineralized Collagen (HMC). The HMC is used to create bone scaffold in bone regeneration process. The suggested manufacturing process for HMC is hybrid process which collaborate Additive Manufacturing and CNC Machining. In this paper, the HMC is reviewed especially related with its properties, fabrication method, and existed experimentation. In addition, the three types of biocompatible composites are also discussed on the applications and its manufacturing processes.

Abstract

The unprecedented Covid-19 pandemic has altered the way educational institutions operate, including Sampoerna University. Distanced learning has been commonly implemented since then. Not only for taught classes but laboratories or practical activities, such as Mechanics of Materials and Machine Shop have also been organized virtually for the undergraduate student in the mechanical engineering study program. Two stages of activities were carried out during the conduct, namely the (1) preparatory stage, where all the teaching materials in the form of videos were prepared, and (2) virtual lab. At the end of the semester, the participating students were asked to fill out a questionnaire to evaluate the entire practicum process. The results revealed that, according to students, teaching and learning activities performed in such a way are quite effective and satisfying. Regardless, based on the survey result, the students expect to have practical activities conducted in person to gain hands-on experience.
