<![CDATA[It has become a habit if students are still often not on time to attend lecture activities, in addition students also often forget to do assignments or prepare to face exams. This has an impact on the achievement of the values obtained not being maximized. In this study, researchers built a mobile Information System on Android-based smartphones as a reminder for students of the Faculty of Information Systems Department of the University's PotensiUtama. This application consists of two parts, namely Web-based for admin and Android-based for users who are connected using Web Service. This application is made in order to support and maximize lecture activities. This application is as a reminder alarm for students so that they always remember the lecture schedule, task collection schedule, and schedule of exam implementation. This Information System is also tested to get the desired results using the Black-Box Equivalence Partitioning testing method. The results of the Black-Box Equivalence Partitioning test show the system can run as expected.]]>

<![CDATA[Transportation is the process of transferring people or goods using vehicles driven by humans or machines. The switching of conventional transportation user services to online transportation is influenced by the sophistication of communication tools (technology) and the desires of the people who always want convenience. GoJek and Grab is an online application to provide transportation services that are currently growing very rapidly in Indonesia and are starting to emerge with several other similar applications that offer various advantages, so that competition is increasingly competitive. Good public transportation must meet three basic criteria: comfort, safety and accuracy. Determining the level of customer satisfaction are five factors: product quality, price, service quality, emotional and convenience. This research is to make a model of Decision Support System (SPK) which is used to help online transportation to know the level of customer satisfaction based on the answers of the questionnaire. The right selection will run effectively and the consumers will be satisfied. The proposed multi-criteria selection model is expected to help consumers identify the best transportation.]]>

<![CDATA[This research is based on recent decades in Indonesia which adopted a general election format to look for Legislative members who would occupy seats in the House of Representatives (DPR) whether in the central, provincial or municipal districts. Each of the Political Parties nominated his cadres to occupy the seat, as well as his cadres who became more and more vigorous to increase their popularity and gain as much sympathy from volunteers as possible. But not a few also the candidates took shortcuts by using money politics in gaining support. Using such politics will have a negative impact on the community as well as the candidate. For the community, it will be a bad example in democracy, while for candidates it will drain a lot of money and make it no longer think of their duties when elected, but he thinks how to return the money he spent to become a legislator and finally corruption. Moreover, if he is not elected, it will greatly affect his life and not a few will go crazy. The above can actually be overcome by using existing technology, namely applying an application that can see the percentage of volunteers who will support it when the election will take place. At least this application can be a benchmark for the candidate to make a decision whether he will run for office or not by seeing the chance he can win or not. If indeed the percentage of volunteers is large then he must be confident to win without having to use money politics. But if indeed the percentage of volunteers is small then he does not need to force himself to use money politics to boost vote acquisition which is sure to be detrimental and not good. In this study the software engineering methodology used in this design is object oriented and the tools used are UML graphic diagrams. While the system design used is web-based.]]>

<![CDATA[Along the development nowadays it is really needed for automatic aquariums which really helps us in doing the water replacement and feeders for fish, which the time usually will be set up on it to replace water and feeders and it will waste time especially in any busy conditions, therefore it was designed a device called Arduino-based automatical fish feeder and water replacement for aquarium. This device used Arduino as a controller device to drive the whole system. This device used a turbidity sensor that served to detect muddy water in the aquarium. Water level sensor was used for measuring water levels in aquarium. The servo motor would give an order to Arduino to open the feeder for fish. Relay was used to turn off and turn on the water pump in aquarium, where first water pump and second water pump also functioned for water disposal and replacement. The buzzer also was used to provide sound signals for feeders and water replacement. LCD would be functioned to display the time, date, woof, and water replacement warning, while Rtc was used to save the time and date.]]>

<![CDATA[Testing of the characteristics and exhaust emissions aims to determine the type of wood that is good for use as an alternative fuel in the future. Based on the description, a laboratory scale tool that is able to provide information on the characteristics and exhaust emissions of biomass is needed, which can also be used as a practical tool so that students are able to understand and know the use of good biomass fuel. Furnaces use refractory cement material for combustion chambers coated with fire bricks, and steel plate casings as insulators. The combustion chamber has a volume of 8,000 m3. The furnace is equipped with additional fan components at the front door to help drain air during direct combustion and gas analyzer sensors to get exhaust gas emissions data installed in the air outlet. The furnace that is made is able to reach a temperature of 800 oC within 360 minutes. The heat transfer rate on the furnace wall reaches 6837.6 W. Mahogany biomass samples have been successfully carried out. The test results using the tools made obtained information on water content of 12.24%, the content of flying substances 83.5%, ash content of 0.57%, and carbon content bound to 15.93%, with the results of exhaust emissions CO = 47.50 ppm , SO2 = 0.11 ppm, and NOx = 0.76 ppm.]]>

<![CDATA[The goal of the distribution system is to deliver the product promptly and generate the minimum cost. The development of distribution system is very important because it can support the growth and development of the company. This study aims to get the route of delivery of the most appropriate and optimal products and get transportation cost savings. IPK is a company engaged in the production of automotive. The problems faced by IPK is the absence of good product distribution planning and scheduling distribution process is considered not maximal. This is due to the number of routes are too many, the distance is too far delivery, the limited means of conveyance and utilization of transport space less than the maximum and the high cost of transportation. To solve the problem is Saving Matrix method which is used to determine product distribution route to customer based on the capacity of conveyance. From the result with Saving Matrix method and algorithm method obtained 49 best route. The distance to be taken is as far as 6,010 kilometers with transportation cost of Rp. 46,630,527. The resulting distance saving is 22% (1,690.9 km), while the transportation cost savings that occur is 38% or Rp. 28,494,021.]]>
