Abstract

Xylitol is a natural sugar that has the sweetness level similar to sucrose, but has lower calorie. It is an important sugar alternate for diabetics people. Reduction of xylose is a normally method to produce the xylitol. It Conducted via chemical hydrogenation of xylose at high pressures and temperatures by reacting pure xylose with hydrogen gas using a metal catalyst. This process requires pure xylose as the raw material. Alternatively, the reduction process can be carried out via fermentation. This process does not require high purity of xylose as the raw material, and thus the oil palm empty fruit bunch (EFB) hydrolysate, without any prior pretreatment, can be used.  In order to scale up the xylitol production via fermentation, kinetic study of xylitol fermentation including growth and xylitol formation kinetic using the synthetic xylose as substrate will be required.  Data used in the kinetic model development were obtained from series of batch fermentations of Debaryomycess hansenii ITB CCR85 varying the initial xylose and glucose concentrations. Yeast growth could be sufficiently modeled using the Monod kinetics, whereas xylitol production could be reasonably well modelled by Luedeking Piret kinetics.

Abstract

In order to evaluation the food security development in Bandung,   researcher has been conducted in the form of software design to measure the performance of food security development from the aspect of food availability, food accessibility and the utilization and quality of food. The software is created in Microsoft Excel base as an analytics tool. The data used as the material of analysis was taken from the report of the institutions related to the food security development. Data here, is a source for scoring and weghting of the  3 food security  dimensions which is  filled in the software. List of contents for the analysis of food availability, food access and utilization and quality of food aspect are consist of 27 criteria, 12 criteria and 12 criteria respectively. The evaluation is done based on the calculation of the total value of weight multiplication with the score of each criteria, where the maximum total value is 5000 and minimum 1000. Justification of performance condition of food security performance described in the software is based on 5 categories class, that is from 1000 to 1800 total value performance for “unsafe conditions”, then 1800 to 2600 for “unsafe conditions”, 2600 to 3400 for “fairly safe conditions”, 3400 to 4200 for “safe conditions” and 4200 to 5000 for “very safe conditions”. The result of evaluation by using data in Bandung City of year 2012 and year 2015 indicate that condition of Bandung food security in terms of availability is “fairly safe”, food access is “safe” and the utilization and quality of food is in “fairly safe” condition.

Abstract

This study aims to identify the changes in Scale-up Business Transformation Process in PT Malabar Kopi Indonesia. PT Malabar Kopi Indonesia is the largest coffee processing business unit in West Java, established in 2005. Initially, this coffee business was categorized to household-scale coffee processing business (Small enterprise scale) and currently the company has become a coffee processing business unit that exports coffee to various countries. The development of this business is eligible to be identify the business changes occured. This study was conducted through field observation and deep interview. The data were analyzed through historical analysis. Through historical analysis approach, all details in innovation process conducted by PT Malabar Kopi will be explained.The results show that the changes on scale-up transformation process is divided into 4 terms, namely product changes, process changes, technological changes, and organizational changes. Product changes occurred four times along the business established. Initially, the company produced cherry bean as the main product on 2005. Changes occurred due to the company's desire to meet the market demand and increase value-added of products on 2009, when started producing green bean and roasted bean. In 2014 they started producing instant coffee and increased the production quantity of Green bean and roasted bean to meet the international market through exporting activity. The Process changes occurred 4 times, it closely related to the product changes. The changes from wet process to dry process occurred on 20014 due to the company target which focused to export market. The change also occurred on 2017 when the dry process moved to the natural process due to the domestic market become the targeted on this year.

Abstract

As a producer of lettuce plants, the company X (as a case object)  needs to improve the information system more effectively and efficiently in order to support the increase of production. Therefore, it is necessary to build a management information system that provides information quickly and accurately. The implementation of this research using Waterfall Method. This research begins with the analysis of the needs of all users, then designing data flow diagrams, designing databases using SQL, entity relationship diagrams, normalization, the latter is the design of information structures including user interfaces. After that done programming activities using PHP programming language. This app is verified and validated. The information needs of the company are as follows: There are four parties as users of the information system; Information should be submitted and accessible as soon as possible; The manager can view the information of each division; To each division and vice versa; Managers can monitor the service level of marketing division and division of production; Each division can manage data; There needs to be model information about the agenda of each division. The app provides a shared menu for admins and users. Users are managers, marketing divisions, production divisions, and home packaging divisions. Each user has the same menu ie homepage, schedule, and reports. As for the manager plus menu monitoring. The final application prototype gives users satisfactory results. Each user is also given a menu to manage the database with features: inserting, searching, editing, and deleting data. The database comes with a dynamic and flexible user interface as a medium of data exchange and information between relevant divisions and media support in decision-making at the managerial level. Keywords— lettuce production,  lettuce production database, production information system
