Abstract

A company that manufactures finished goods often faces a shortage of raw materials, due to the determination of the quantity of raw material ordering improper because it is done by intuition and the lack of raw material inventory reserves. This resulted in costs because inefficient production processes are inhibited or had to perform an emergency procurement of raw materials to meet customer orders. The company seeks to use the method in determining the order quantity of raw material, comprising the steps of (1) collecting historical data of raw material use, step (2) forecasting needs raw materials, step (3) calculating the order quantity forecasting based on the data by comparing the deterministic method and probabilistic methods. Calculating safety stock for each raw material is done so as to cope with the situation outside of normal conditions, such a surge in orders. In its design, the system will be developed using the Unified Modeling Language modeling language (UML) on the basis of the concept of object-oriented analysis and design (Object Oriented Analysis and Design). With the proposed implementation of the information system, the company can estimate the need for raw materials more quickly and accurately, and can determine the order quantity that is tailored to the needs. So that the costs associated with ordering and storage of raw materials can be minimized.

Abstract

The idea to design an information system in PT Triwarna Eka Multimedia arises because of the current information system is still very traditional and it has an enormous dependency to physical data. Designing of an information system in PT Triwarna Eka Multimedia is aimed to identify the organization needs in managing their business process operational related to current data of sales, production and inventory. The result from those processes is aimed to build an integrated system that can meet all of the organization’s needs in running their daily business process and facing the rivalry from the competitors. The method used in this paper is a survey, literature review, and analysis of current business processes in the company These needs will be documented by using unified modeling language. This information system makes all the current operational business activities easier with the more enhanced automation than the previous information system. This system will also minimize the data lost and human error, which is usually cause by the manual process and storage data of physical data.

Abstract

If there is a stack in a service center, then the customers need to form a queue. There are increasing number of consultations in a specific time at Student Advisory Center (SAC) Bina Nusantara University. The increased needs for consultation lead to high waiting time that must be passed by the students who need the service. Therefore an information system queue is required to replace the current manual queue process. This study aims to create an automation using six stages FAST Methodology which includes Scope Definition, Problem Analysis, Requirement Analysis, Logical Design, Decision Analysis, Physical Design and Integration. The results of this research is the design of the application queue screen can be applied to SAC Bina Nusantara University.

Abstract

Subjective fatigue measurement instruments, based questionnaire, is a measure that is widely used for reasons of practicality and measurement results can be obtained quickly. For the purposes of measuring fatigue, there are a number of questionnaires commonly used abroad, but not a lot of literature with a case study in Indonesia that utilize this instrument. Of course, the reason for the use of the instrument is based on the expectation that the instrument has high validity and reliability, and if possible to have a high level of practicality as well. Asssment Fatigue Scale (FAS) is one of the suggested use as a measurement of worker fatigue. The instrument consists of a 10 item questionnaire with good reliability level. The discussion in this paper covers Measurement Scale Fatigue testing results via questionnaires measuring fatigue, adapted from the FAS in English and translated into Indonesian. DSS consists of 10 questions using 5 Likert scale, for the answer options are: never (1), sometimes (2), perceived a regular basis (3), is common (4), is always experienced (5). Relaibilitas test results using Cronbach alpha values obtained value of 0812, and can be improved if the item is question number 3 is removed. By implication, this questionnaire is good enough to use as a measuring instrument fatigue, but the level of proficiency in Indonesian language, in this CMS, needs to be repaired, especially for question number 5 and 3 if the level of validity and reliability to be improved, although the increase may not be too significant.

Abstract

Red tilapia is a good commodity to be developed because it has a high nutritional value composition, with a protein content 17.8%, fat 2.8%, and others composition. The fillet of red tilapia fish is easy to spoil, because of S. aureus, Salmonella sp., and other microbes. Many methods are used to save and preserve the quality of fillet, such fillet preparation through good sanitation practices, cooling process, but the effort were not optimal. The objectives of this study were to 1) evaluate the potency of antibacterial produced by Lactobacillus acidophilus and Bifidobacteria biffidum to inhibit the growth of spoilage bacteria that contaminated the red tilapia fillet; 2) evaluate the effect of antibacterial compounds produced by Lactobacillus acidophilus and Bifidobacteria biffidum of inhibiting the setback fillet quality, 3) determine the shelf life of red tilapia fillet at room temperature. Antibacterial activity test is done by using the well diffusion method; the rate of deterioration of quality of fish tests done by observing the organoleptic parameters, pH measurement test, total volatile base method. Total number of bacteria were performed by Standard Plate Count (SPC) test. The LAB’s are able to inhibit the growth of spoilage bacteria Pseudomonas aeruginosa about 8.67-9.00 mm and Listeria monocytogenes about 8.33-9.00 mm through the well diffusion method. pH values about 5.71-5.74, TVB values about 1,26-21.43 with SPC test about 1.39-4.83 CFU/mL. The antibacterial compounds could inhibit  the rate of deterioration of quality red tilapia fillets until 14 hours.
