Abstract

The train station is an important facility. However, the services provided to train passengers are still not optimal. There are still several weaknesses, including the arrival and departure processes of trains that still rely on telephone communication with other station staff. Notification of train arrival will be sent by telephone by the officer at the previous station to the destination station. On receiving notification of arrival, station staff will close the train portal. This process can have a weakness, and namely, if there is the officers' negligence, it can cause an accident. This is due to the absence of an automatic operating system on the railroad crossing portals. Because the manual system must use human labour or operators to operate and open the railroad crossing portals, so that operator error or failure of manual operation of the portal can increase the likelihood of a train accident occurring at the crossing portal, the above problems can be overcome by implementing an automatic portal closure system. With an automatic portal system, the portal will automatically close if a train passes through the crossing.

Abstract

Product promotion is a way for business owners to increase sales of existing goods. Business owners could use association rules as a consideration of product promotion policies. Determination of association rules can be determined using the market basket analysis method with the fp-growth algorithm. From the research, there are 248 association rules for goods that are often purchased simultaneously with minimum support of 0.01 and minimum confidence of 0.1. Of the 248 rules, there are seven rules that have a confidence value of more than 0.5. Of the seven rules, flour appeared five times, and the cake mat and cake box had the highest confidence value of 0.62 and a lift of 5.54. Therefore, we recommend shop owners to place wheat flour on the main display close to items often purchased together, such as sweetened condensed milk, sugar, powdered margarine, and margarine. In addition, shop owners can also promote bundling cake boxes and cake mats.

Abstract

On average, students of the Yogyakarta Nahdlatul Ulama University (UNU Yogyakarta) have difficulty accessing course materials and self-assessments from e-learning platforms without the internet. The author uses a qualitative method by using observation to get direct information about access to course material from the e-learning platform. The mobile learning (m-learning) application prototype was developed through the android platform using the Java programming language. As a result, the use of m-learning can be one of the best modules of mixed learning techniques. The author recommends that UNU Yogyakarta integrate it with their e-learning platform. This m-learning application intends to complement the e-learning system and make students whenever and wherever they want to gain knowledge without the internet via an android phone. Future researchers can connect the m-learning application and other aspects of the e-learning platform.
