Abstract

The efficacy of noni juice (Morinda citrifolia L) for health is very diverse, and has been known for thousands of years. Noni fresh juice contains a relatively high concentration of vitamin C (ascorbic acid) and scopoletin which is known as an important antioxidant and a herbal compound having multy efficasies for health, repectively. Recently, many processed juice products have been widely offered in Indonesia either as medical products or nutritious drinks in liquid and solid forms stored at cold or room temperature for a relatively long period of time, however no one of these products could show the amount of active compound after storage. Vitamin C and scopoletin in noni juice could be changed during storage. This study was aimed at investigating the effects of storage temperature and time on the vitamin C and scopoletin concentration of noni juice. It was conducted at Food Laboratory, AKA Polytechnic Bogor, Indonesia, and the noni juice investigated was packed in plastic containers/cups and stored either at room temperature of 28 oC or in a refrigerator having a temperature of 6oC. The investigation was carried out for 3 (three) parameters i.e pH, vitamin C and scopoletin contents. From data obtained, it can be concluded that there were a decrease of scopoletin and vitamin C concentration remarkably, while pH value was relatively stable (between 4.5 to 6.2) during storage of noni juice, either at room temperature or cold temperature. However, there was still a remarkable amount of scopoletin concentration after 10 weeks of storage (14.21 mg/ liter), that was more than 50 percent of its origin (26,93 mg/liter), fresh noni juice, contrarily vitamin C was almost no more available in the juice after 4 weeks of storage either at room temperature or cold temperature. This vitamin C might not decrease only as a result of oxidation but mostly also because of its proton release and develop a buffer solution, as indicated by the pH stability during storage.

Abstract

An employee performance appraisal process is a set of certain processes which will produce a value from the employee's performance in a certain value, either in percentage or in another unit of value. In an employee appraisal process it will be difficult when the structure of the problem and how to solve it are unknown. Assessing employee performance will be easier if you know the structure of the problem and know how to do it. In this study, we tried to apply the Weighted Product (WP) method in an employee performance appraisal process. The problem of evaluating employee performance can be approached using the Multi Attribute Decision Making (MADM) approach. With this approach, one of the methods that can be used in solving the Multi Attribute Decision Making (MADM) problem is chosen, namely the Weighted Product (WP) Method. The difficulties experienced by a company in carrying out the employee performance appraisal process are due to the absence of certain criteria that can be used in evaluating employee performance. This research seeks to find criteria that can be used in the employee performance appraisal process. In addition, this research will also design a Decision Support System (DSS) that can be used in the process of evaluating the performance of employees in the company. Based on the research that has been done, several criteria are obtained that can be used in the process of assessing employee performance, namely responsibility, discipline, communication and skills and loyalty. In addition, based on the results of system testing that has been done, it can also be concluded that the Decision Support System (DSS) that has been designed can be used as a tool to facilitate the employee performance appraisal process. Keywords: Performance Assessment, WP Method and Decision Support System (DSS) ABSTRAK Suatu proses penilaian kinerja karyawan merupakan suatu kumpulan proses tertentu dimana akan menghasilkan suatu nilai dari kinerja karyawan dalam satau nilai tertentu, baik dalam persentase atau satuan nilai yang lain.

Abstract

In the current furniture industry, making furniture goes through many steps. There are ordering materials, designing, building a prototype, and testing samples. This process is considered quite complex, requiring significant costs, and lengthy production time. The application of finite element analysis (FEA) can be a solution to simulate the furniture manufacturing process. Objective of this research was to determine FEA could substitute making and test prototype furniture thereby saving costs and time. This method utilizes ANSYS 18.1 software for more accurate and rapid calculations, incorporating load variables of 400 N, 600 N, 800 N, and 1,000 N, along with gravitational acceleration of 10 \frac{m}{s^2}. The research evaluates the difference (expressed as a percentage) between the results obtained from simulations and those obtained directly from experiments, considering maximum equivalent stress, maximum principal stress, and total deformation values. The final step involves comparing the simulation with direct testing in terms of cost and time. The research results show an average error factor of 5% across all aspect. In terms of cost, the method can save 1,807 USD and reduce production time by up to one month. From these findings, it can be concluded that the process of prototyping and sample testing can be replaced using the finite element method.

Abstract

Coffee table is quite important furniture because it is located in the center of the family room, so the coffee table must appear functionally and aesthetically attractive. Currently, minimalist and multifunctional furniture is growing rapidly with the extendable trend. This research aims to design a coffee table that can be opened lengthwise (extend). The Internet of Things (IoT) feature was added to make it easier to use this coffee table and to follow modern furniture trends. On the other hand, the industrial challenge is an environmentally friendly industry, such as minimizing waste by utilizing leftover materials that can still be used. This research also utilizes industrial wood waste. The coffee table designed in this research can be opened to the side so that it has an additional function as a place to store items. The type of research used is Quantitative Research using the design thinking method as a research method as well as a design method starting with empathy and ending with a test. Both the empathize and test stages use questionnaires as a measuring tool.  The result is that the function and aesthetic value of the extendable coffee table is quite good in terms of size, scale, proportion, texture, pattern and color because it uses appropriate finishing materials. The application of IoT in the design of an extendable coffee table shows that this product can follow technological trends in furniture design in the future and make it easier for users to operate furniture in storage functions without having to use a lot of manual effort.
