Abstract

School payments are a very important issue to support a school that is used to meet infrastructure and other needs. Therefore, if there is an error in writing or the loss of payment data, a difficult problem will arise. Because the payment process is still manual using a notebook.By utilizing E-money and RFID Sensors in the school payment process, it will be very helpful to create an effective and efficient payment process. That is by using school student cards as self-identity in searching for data that will be linked to a web as a basis. In paying school fees, you can also use E-money for the payment process. Therefore, the author will use electronic money to process the payment. That is by utilizing server-based electronic money in the form of applications such as OVO and DANA. Because it is easier and has been registered with Bank Indonesia, it will be guaranteed safe. The way it works is the first by installing an RFID sensor on the student card which functions as a means of finding personal data or identity so there is no need to search for data one by one manually. Furthermore, it will be linked to the website as a payment basis, where when the RFID sensor is successful in scanning student data, a payment option will appear, which can be paid directly or through the available OVO and DANA electronic money.

Abstract

Makerspaces are now fixtures in smart cities and universities in advanced countries. Many universities, especially in the United States, have Academic Makerspaces serving students and faculty, helping them with their projects. In Bataan Peninsula State University our goal is to have an Academic Makerspace with services and facilities at par with international standards. This Academic Makerspace will be a place where our students can ideate, conceptualize, build and manufacture their projects, either academic projects,  or just extracurricular projects they are interested in. The goal is to promote invention, innovation, creation and making. This study summarized the best practices of Academic Makerspaces in the United States. The practices of local innovation centers were also benchmarked. With this study, we have identified what facilities are needed, which equipment to purchase, and what kinds of programs should be made available in the Makerspace. Fund source, possible partner agencies, and other important details have been discussed. This study provides short- and long-term plans/programs which would be very important in the establishment of BPSU’s Academic Makerspace. These plans will be used to recommend future facilities/services in BPSU.

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

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.
