Abstract

According to UNAIDS until 2018, there are around 690 thousand people with HIV in Indonesia. Until now HIV is a virus that is slow to diagnose, but there are ways that can be used to diagnose the HIV virus. One way to find out whether someone is infected or not is by taking HIV test accompanied by counseling in the clinic (Voluntary HIV Counseling and Testing). Prospective patients feel ashamed during the initial diagnosis of a health examination. To solve these problems, it is necessary to build a system capable to diagnose HIV / AIDS using the best first search algorithm. The result of this study is to be able to facilitate patients checking their health by computerization easily, quickly and precisely, especially about HIV AIDS. Based on the system evaluation of the respondents, RK test results are obtained from the convenient use of the HIV expert system application that has a value of 3.72 with the title of satisfaction. the RK test results from the benefits of using the HIV expert system application has a value of 3.96 with the title of satisfaction.

Abstract

SMK 2 Cimahi is an educational institution Vocational high school in Cimahi. Vocational high schools play an important role in creating the best graduates for the needs of the workforce. The graduation process is the latest activity of student management. Student graduation criteria for national exams must meet minimum scores, complete all subjects, take school exams, national exams, and competency tests. In the 2015 class of 300 students, students who did not pass the national exam were 1 student, in the 2016 class of 299 students, students who did not pass the national exam were 1 student, whereas in the 2017 class totaling 302 students 100% students graduate on time. However in the coming year, it is still unknown whether students will be 100% graduated or not. Therefore this study was conducted to predict student graduation using the C4.5 algorithm + Genetic Algorithm. C4.5 algorithm has an accuracy rate of 99.78%, precision of 99.78%, 100% recall and 1 second execution time. While the C4.5 + genetic algorithm has an accuracy rate of 99.78%, precision of 99.78%, 100% recall AUC 0.500, and 36 second execution time and after T-test testing between the C4.5 Algorithm and C4 Algorithm .5 +, Genetic Algorithm is said to be significant if alpha = 0.050. The results of this study obtained alpha = 1,000.

Abstract

Investment is a principle thing in the business world, because investment is one source of capital that can be owned by capital holders. The public still has a perception that shares or capital markets or exchanges are something complicated, expensive and have high risk. A survey conducted by OJK in 2012 explained that the level of literacy and financial inclusion of Indonesian people was still relatively low at only 3.7 percent literacy and accountability. Only 0.11 percent is inversely proportional to the number of Indonesians whose numbers are always increasing every year. Let's Save Stocks is a campaign that was inaugurated in 2015 by Indonesian Vice President, Yusuf Kalla in enhancing the role of the community in shares. An interesting promotional media is needed to introduce shares to the public, one of which is an animated film that is able to be consumed by people of all ages, education and economics. Moreover, motion graphic is a technique that is able to make still images to move and be interactive.

Abstract

The population of vehicles in indonesia, always has increased, this has an impact on oil fuel consumption continue to grow also, reduction of fuel consumption in vehicles can be done by the method of eco driving, one of the methods in eco driving most easily applied is the speed settings, gear position, and the selection of the right type of Transmission, but the information setting the speed and position of the gears on each vehicle is definitively less Thus, do the research to find speed settings and the position of the gear is done. This research was conducted on the analysis of the results of calculation of the Specific fuel consumption of vehicles bus with the variations of the two types of transmissions, to know the pattern of the ride's low Specific fuel consumption and the type of transmission the best of transmissions to two. The results obtained from this study, Specific fuel consumption bus will continue to decline at 1000-1300 rpm, but will slowly climb back on 1400-2300 rpm, while the increase in speed is directly proportional to the increase of rotation of the engine, transmission Type MB GO 190 is the most excellent transmission among other transmission a third because of the difference between the rate ratio in this transmission is not too far away so that fuel is wasted due to a pause on this transmission traction loses a little and acceleration of the vehicle a smooth and fast.

Abstract

The Indonesian government conducted a household fuel conversion program in 2007 using LPG as a substitute for kerosene. LPG gas is the most widely used energy source for the people of Indonesia. Currently the quality of LPG gas cylinders tends to decrease. This quality degradation can occur due to lack of supervision during the production process, especially in the quality control process, so the use of LPG is quite dangerous with the potential to cause an explosion to fire. The aim of this research is to design and build a prototype of a gas and fire leak detection system using Arduino. The method used in this research is the prototype development method with the stages of listening to problems and customer needs, building a prototype, then the customer sees the prototype and tests it. The results of this study are tools that can detect LPG and fire gas leaks using an arduino microcontroller that can be accessed using a smartphone with an average response time to detect a fire of 4.43 seconds while to detect a gas of 4.18 seconds.

Abstract

Universities are educational institutions that cannot be separated from student service activities, especially student letter services. Currently, student letter service activities at the TEDC Polytechnic Bandung are still using conventional methods. Students who wish to make certain letter submissions must often fill in data on paper forms to make letter submissions. The problems that occur are the data is not well organized, the large number of papers that must be printed for service forms of various kinds of letters and also service officers still have to enter data on the form into letters submitted by students manually. Based on this problem, it is necessary to create a student letter service administration system to manage various student letter submissions. The method used in this research is waterfall. The database design uses MySQL and the programming languages used are PHP and Java. The result of this research is that there is an administrative system that is able to manage student letter submission data, starting from submission, letters being processed, to giving notification to students that the letter has been processed. From the test results, 82.8% of respondents agreed that the system was able to manage student letters.
