Jatinangor, the house for various Universities amidst the pleasant environment is an ideal venue for the conference.

ICePTi 2017, organized by Nanotechnology and Graphene Research Center (Print -G), Science & Technology Park Unpad (KST-Unpad), Material Science & Engineering (MSE) Study Center Unpad, Indonesian Powder Association and managed by JP Global Transtech. In connection with this event, The 4th Japan Powder Technology Forum was held in Indonesia. The objectives of this forum is to acquaint with the field of powder technology and technologies developed by Japanese companies.

This conference is aimed at elevating the scientific communities, explore new ideas, research progress, technological developments and light up collaboration between researchers and industries, in powder technology and its applications. Exhibition was also organized to promote the new products or technologies developed under these four categories: Manufacturing & Processing Equipment, Instrumentation, Measuring & Laboratory Equipment, Materials Engineering, Science & Technology Park Unpad.

There were 14 invited speakers, 49 abstracts and 63 scientific participants from countries like Indonesia, Japan, India and United States, contributing to the overall success of the Conference. The abstracts were considered under two categories, powder science & technology and powder applications. Among the total number of presented abstracts, 52 articles were published in AIP Conference Proceedings.

Generous support for the conference was provided by Rector, Directorate of Research and Community Service and Innovation, Universitas Padjadjaran.

On behalf of the organizing committee, we would like to register our thanks to the advisory committee, participants and all who have supported to the success of this scientific meeting. We would also like to thank all the members of the organizing committee, it is our privilege and honour to be the corresponding Editors.

Abstract. This research aimed to produce fine chitosan particles from a crab shell waste by beads-milling method by two different concentration of PEG as dispersing agent (150 and 300 wt. %). The characterization was performed to obtain the size and size distribution, the characteristics of functional groups and the degree of deacetylation. The results showed that the chitosan fine particles was obtained with a milling time 120 minutes with the best concentration of PEG 400 150 wt. %. The average particle size of the as-prepared suspension is 584 nm after addition of acetic acid solution (1%, v/v). Beads milling process did not change the glucosamine and N-acetylglucosamine content on chitosan structure which is indicated by degree of deacetylation higher than 70%. It was concluded that beads milling process can be applied to prepare chitosan fineparticles by proper adjustment in the milling time, pH and dosage of dispersing agent.

INTRODUCTION

Chitosan is a natural polysaccharide and is considered as the largest biomaterial after cellulose in terms of utilization and distribution [1]. It is produced from chitin the structural element found in the exoskeleton of crustaceans such as shrimps, lobsters and crabs. Chitosan can be used in many areas of modern industry, such as pharmaceuticals, biochemicals, cosmetics, food industries and textile industry [2]. In the field of food technology, chitosan was developed by changing the particles size to become fine particles i.e. micro/nano as reinforcement for the biocomposite films. Using fine chitosan particles as filler in biocomposite film would enhance the properties of film such as mechanical and barrier properties [3]. Additionally, chitosan compared to other bio-based food packaging materials has the advantage of antibacterial activity [4]. Fine particles of chitosan are prepared using number of different strategies. These include cross linking, ionotropic gelation, microemulsion, emulsification solvent diffusion and polyelectrolyte complexation [5]. All these techniques adopt a “bottom-up” approach where particles are generated from individual macromolecules through self-assembly [6]. Extensive work had been carried out by adopting bottom-up strategies to prepare fine chitosan particles, however research carried out using top down technologies are almost insignificant [7]. Beads-milling is one of the equipment of top-down process for size reduction of bulk particles into fine particles. Furthermore, bead milling is capable of producing fine chitosan particles in suspension, since it allows using smaller beads around 0.015 to 0.5 mm and applied with a dispersing agent [8]. Therefore, the objective of this study is to obtain the well-dispersed chitosan suspension by beads milling
