Abstract

Red ginger (Zingiber officinale var. Rubrum) is one of the most popular plants in Indonesia. Generally, the processed product is distributed in the community in the form of red ginger extract powder. This study examines the production of processed red ginger products in the form of red ginger powder with variations in temperature treatment (80 and 90°C) and the percentage of sugar cubes (60 and 100%). The purpose of this study was to determine the effect of temperature variations and crystallization agent levels on the porosity value of red ginger powder products, both research results and commercial products that have been circulating in the market. Analysis of test results obtained from scanning electron microscope (SEM) surface morphology images with prior conversion to matrix data The analysis step utilized the Origin program version 2019b. The results of the study with four treatments gave a positive value for porosity. The best treatment obtained was at 90°C and 100% sugar content for residual red ginger raw material (pulp). The highest porosity value for red ginger powder was 76.48%. Meanwhile, the highest commercial product was 77.00%. Indirectly, the research product has a porosity value that is close to the commercial product. The surface area of the product can significantly influence the porosity value between powder and granule products from ginger processing in an effort to increase post-harvest shelf life.

Abstract

A bachelor's degree in chemical engineering enhances one's capacity to adapt both hard and soft skills in the classroom and at work to the quick changes in technology and increasing competitiveness in the professional world. This motivates an individual who has graduated from chemical engineering to enhance the caliber of their work. Technology for simulation programming is one of the hard skills he needs to possess. In the realm of chemical engineering, these abilities encompass not only using Microsoft Office but also making objects work with other software. Through theoretical research on cases in the process industry, the simulation program is used. Prioritizing the operational foundation of an application is essential for work in the chemical sector. It is recommended that a graduate of chemical engineering possess software capabilities in order to facilitate their employment in the workforce. Basic requirements and increased proficiency can be supported by theoretical and data processing techniques. This article discusses the need for software skills in the field of chemical engineering, such as Aspen HYSYS, Matlab, AutoCAD P&ID, and Scilab, using a literature study methodology. This endeavor is a method of looking through library data for pertinent articles and then delving deeper into an article's content. The purpose of this article review is to balance hard and soft skills in order to determine how software is used in the field of chemical engineering and what is required in the chemical industry.
