Abstract

Netasia is a brand activation of the company named Golden Style Management Lte. Ptd. in Singapore which acts as a local partner and distributor for Small and Medium Enterprises (SMEs) from Indonesia. Netasia utilizes Content Management System (CMS) named Shopify to reach end-users. But currently, they do not have a platform for managing product distribution from preorders to vendors until distribution to stores. This research was conducted to develop a web-based application of SMEs product distribution management with CMS Shopify integration in Netasia Singapore. This research was conducted using Research and Development (RnD) method for research approaches and prototyping method for software development. The prototyping method often involves communication between developers and the company as application users, so that the application undergoes several changes. As the result of this research, the application has been successfully integrated with the data from the company's CMS Shopify through the API using cURL. The application was tested with several testing methods such as 1) black-box testing with 100% succeed percentage so the application is proper to use, 2) white-box testing with cyclomatic complexity of 4 and 100% succeed percentage for value test so the application passed the software engineering criteria, 3) User Acceptance Testing (UAT) with 94% average percentage so the application meets user expectations, and 4) browser application compatibility testing with the results that the application is compatible with all of the browser applications specified in this research for the menus function aspect, and less compatible with the Internet Explorer browser for the user interface aspect.

Abstract

Although ballast is only part of the substructure, it plays an important role in keeping the railway track in position. But less attention has been given to the substructure because the properties of the substructure are more varies and difficult to define than those of the superstructure. Research about ballast behaviours still needs to be developed. Objective of this research is to use Los Angeles Abrasion (LAA) and Aggregate Impact Value (AIV) test to analyse the strength of nature rock (NR), slag (S) and their different combination. Four different types of samples have been prepared for testing. LAA and AIVtest has been performed to assess the strength of the ballast. Finally, the result shows that the combination of slag and nature rock showed good results, even not really significantly. The result for 25%NR+75%S (LAA test) and 1NR+2S (AIV test) is 7,41% and 6,02%, respectively.

Abstract

White tea is a type of tea that still sounds foreign, the high price makes white tea sometimes used as a symbol of one's social status. Due to the high price, not many people consume it, so it is less popular. PT. Perkebunan Nusantara IX  (PTPN-IX) which is located at the west foot of Mount Slamet, precisely in Pandansari Paguyangan Village, Brebes Regency, Central Java, with an altitude of 1,500-2,050 meters above sea level and a temperature between 8-280 Celsius. One type of tea product PTPN-IX that has not been studied physically, chemically and its characteristics is white tea. This study aims to examine the characteristics of white tea produced by PTPN-IX in Brebes. This research was carried out at the request of the PTPN-IX, the methodology used was to test some of the core components contained in white tea, some tests were carried out 3 times and the average value was taken. The components tested included: ash content, crude fiber, Pb/Cu/Zn/Hg content, total plate count, coliform, water content, carbohydrates, protein, pectin, tannins and caffeine. The results showed that white tea produced by PTPN-IX were: ash content of 5.70%; Crude fiber 13.40% ; Pb 2.35 mg/Kg ; Cu 12.94 mg/Kg ; Zn 22.30 mg/Kg ; Hg ( negative ) ; Total plate number 1.3 x 103 efu/g ; Coliform (negative). For chemical components, the results are: water 5.65%; carbohydrates 3.9% ; 18% protein; pectin 5.85% ; tannins 5.25% ; caffeine 2.4 – 4.5

Abstract

Rice (Oryza sativa L.) is the primary staple food for half of the world population. It is generally classified based on the grain color into black, red, purple, brown, green, and white. These colored rice are determined by the composition and concentration of anthocyanin pigments in different layers of aleurone, pericarp, and seed coat. Anthocyanins are also accumulated in various tissues of the rice plants, mostly in the grain, but are also presents in leaves, leaf sheath, floral organ, and hull. The type and concentration of the anthocyanins in rice tissues are influenced by the cultivars and developmental stages. Anthocyanin-enriched rice is related to the health effects, including antioxidant, antibacterial, and anti-inflammation activities that potentially use as functional food ingredients, dietary supplements, and natural colorants. Structural and regulatory genes are involved in anthocyanin biosynthesis of rice. Various molecular biology techniques have been applied to improve productivity, nutritional contents, and market value of pigmented rice. This review focused on the genetics, biochemistry and biophysical analysis of anthocyanin in rice that will facilitate rice breeding program to develop new high-yield pigmented rice varieties.

Abstract

Sausage is a processed food product that is generally made of meat, fat, filler, water, binder and salt. Catfish is a source of animal protein that has advantages compared to other animal products, namely catfish which is rich in lysine, and leucine. Moringa leaf flour is Moringa leaves that are given drying, milling treatment to facilitate processing into various food products and as a fortification material with high nutrition. This study aims to determine the effect of differences in concentration of catfish: tapioca flour with the addition of Moringa leaf flour on the physicochemical properties of catfish sausage. The results obtained in the study that the difference in the concentration of catfish: tapioca flour and the addition of Moringa leaf flour affect the analysis of water content 58%; fat content 13%; ash content 1.85%; protein content 18.09%; color parameter L* 47,26-66,48; color parameter a* (-4.43)-5.40; color parameter b* 14.25-26.71.

Abstract

The plotter is a graphic printer that draws using ink pens, the plotter is also the first output device capable of printing large-sized images of architectural and engineering drawings. A plotter is a type of printer that is specifically designed to produce computer output in the form of images or graphics. There are many types of plotters, one of which is the pen plotter, which has one or more colored pens for drawing on transparent paper or plastic and producing a line output. CNC (Computer Numerical Controller) is one of the machine control tools in large industrial factories. With the CNC can control most of the tools one example is as a controller of a 2-dimensional plotter. This research designs a 2-dimensional plotter using Arduino UNO-based CNC. This 2-dimensional plotter has an accuracy of 97.947% and a precision of 99.985%. This 2-dimensional plotter is capable of operating up to a distance of 4cm with a resolution of 0.01cm.

Abstract

Attendance management is a problem commonly faced by companies, management using a manual system still causes problems. The problem that is often faced is the difference in employee attendance data reports because they have not been well integrated. The purpose of this study was to design an employee attendance information system at PT. Kartika Utama Semarang. From the above problems, a system is needed to integrate these needs automatically and is managed entirely by a computer using an RFID system in it so that the leadership can monitor attendance and payroll in real time. The application of the author's research and development (R&D) research method in this study. This research resulted in an information system application to facilitate the management of attendance and payroll of PT. Kartika Utama Semarang
