Abstract

There are still not many SMP/MTs/Equivalents in Indonesia holding online New Student Admissions, one example being MTsN 4 Kab. Lima Puluh Kota under the auspices of the Ministry of Religion Kab. Lima Puluh Kota. During manual PPDB at MTsN 4 Kab. Lima Puluh Kota there are several obstacles both experienced by the school, prospective students and parents, both in terms of administration or information at the time of PPDB implementation. Another problem that arises is the distance of the radius and distance of students who will register to school; from the data, the authors found that the radius and the furthest distance traveled by students was ± 18-20. It is the author's background in designing an Android-based PPDB information system using the 4D version of the R&D method with the SDLC waterfall system development model. The programming language used is PHP language assisted with MySQL database. From the product test that the author did, the results obtained: the validity test was carried out by filling out a questionnaire that referred to the Aiken's V statistical formula, namely 0.80 Valid criteria addressed to 3 lecturers, the practicality test was carried out by filling out a questionnaire which was analyzed with a percentage per rhythm, namely 93 ,33 Very Practical criteria aimed at 3 teachers and the effectiveness test is carried out by filling out a questionnaire that refers to the statistical moment kappa formula, namely 0.91 Very Effective criteria addressed to 15 students.

Abstract

WHO in 2013 released data in the Global Tuberculosis Report that 8.6 million more people were positive for TB, and 15.12% of them died. One of the causes of death due to tuberculosis is too late to know when it is infected and too late to get treatment. For an initial diagnosis of whether someone has TB, they can immediately go to a hospital or use a computer application that has an expert's ability. This study aims to design an expert system for the early diagnosis of intestinal tuberculosis using the Forward Chaining method. Expert System is one part of Artificial Intelligence that can create a computer program to provide decisions and analysis like an expert or expert in a particular field. The research method used in this study is the Research and Development method with the ADDIE approach. The expert system for early diagnosis of intestinal tuberculosis is designed by making a decision tree diagram to find out the rules needed to diagnose whether a person has intestinal tuberculosis from the symptoms experienced. The formulation of the problem or the rules needed for the initial diagnosis of intestinal tuberculosis in this study was built using the Forward Chaining method. The output of this research is an Expert System in the form of a Stand-Alone application that is built with the Visual Basic Programming Language, which can provide diagnostic results whether a person suffers from intestinal tuberculosis from the symptoms entered into the Expert System Interface.

Abstract

This study aims to create new business opportunities for students using information technology (IT) and the internet by becoming entrepreneurs. The basic concept of using IT and the Internet is to be the main actor in the development of e-commerce and to be a part of it by using certain methods. One method that can be applied in e-commerce is the dropshipping method. With this dropshipping method, anyone can sell goods/services without having to have a stock of goods/services simply by collaborating with manufacturers, shops, and suppliers. The method in this research is an experimental research method. Explorative research aims to explore or deepen knowledge, phenomena, and new ideas to formulate problems in detail. From the research results on 32 students who became participants, the success rate of implementing the dropshipping method in this study was 71.87%, namely 23 students succeeded in selling products while nine other students failed to sell products or 28.13%. This direct practice's high level of success can be used as a reference for development and broad application in creating new business opportunities for students by becoming a dropshipper.

Abstract

This study aims to design a Web-Based Online Registration Information System Supported by SMS (Short Message Service) Gateway at Alhira Middle School that is valid, practical, and effective. The process of registering new students, which has been taking place at Alhira Junior High School, has not yet run online; this can be seen from the data process, report generation that still uses Ms. Office Word, and use paper archives. It makes data security not guaranteed, allowing much data to be lost. On the other hand, for prospective registrants who want to know information related to schools, it is still difficult to do, because it requires prospective registrants to come or visit the hut directly. Another problem is that more prospective new students come from outside the Tanah Datar area, of course, it requires a lot of costs, especially transportation. This problem is the background of this research. The type of research used is Research and Development, with the 4-D model stands for Define, Design, Develop and Disseminate. While the system development model used adopts the SDLC cycle (System Development Life Cycle, namely the waterfall model. The results of this study are a new student registration information system that has been tested for products including validity, practicality and effectiveness tests. The results of the validity test were carried out on three people; the validator obtained a total score of 0.88 with very valid criteria, the practicality test was carried out on three validators obtaining a total value of 93.33 with very practical criteria, and the effective value for ten respondents obtained a total result of 0.79 with very effective criteria. After testing the product, this information system can be declared feasible and can be used in the process of accepting new students at Alhira Middle School.

Abstract

E-commerce applications to sell various products produced by students in higher education can increase income-generating. However, a few universities still use e-commerce to sell student products, especially learning products. This research aims to produce an e-commerce application for web-based learning products in universities. The research method is development research with a research design using the waterfall model. The waterfall model procedure consists of analysis, design, coding, and testing. The system design uses Unified Modeling Language (UML) modeling such as context diagrams, class diagrams, use case diagrams, and activity diagrams. The system's coding uses the PHP programming language, Jquery, and the Boostrap Framework. The testing stage is through black-box analysis carried out by experts in the field of system design, with the results of testing each case being well-integrated and feasible to be applied. The result of the research is a web-based e-commerce application that sells learning products in universities.

Abstract

Sociometry is something that can be used in studying the structure of social relations among a group of individuals on the basis of research on social relations and social status of each member of the group concerned. Currently the service of sociometric instruments in the guidance and counseling laboratory of the Bukittinggi State Islamic Institute is still using conventional techniques using Ms.Excel. It is done manually using the distribution of questionnaires, Ms.Excel, which is still combined with Ms.Acces, which is not online yet , so that it can only be distributed in labor, and the next problem is that the application that uses Ms.Excel cannot yet display sociometric reports graphically. The research method that the author uses is the R&D Research & Development method with a waterfall SDLC (System Development Life Cycle) system development model consisting of the Communication.Planning.Modeling stages. Construction.Deployment. For the product test that the author did, the results obtained: the validity test by the validator obtained a value of 0.85 with valid criteria, the practicality test by the practitioner obtained a value of 0.83 with the Very Practical criteria, and the effectiveness test by the effectivator obtained a value of 0.75 with the Very Effective criteria.

Abstract

Decision-making in determining product orders is a method that managers can use to determine the type of product to be ordered again based on previous sales. Product orders to be reordered will be determined based on the highest number of sales among similar products. One of the methods that can be used is the AHP method, where the AHP method can assist managers in making decisions by providing a sequence of decision alternatives accompanied by a percentage on each alternative. The research method used in this journal is the system development life cycle (SDLC) which can describe the activities in this research in detail. The application of product orders with the AHP method will be applied to a case, namely an order for clothing products at a well-known clothing outlet in Bukittinggi. The product order system will be implemented into an application designed with the Visual Basic 2010 programming language and MySQL database to make it easier for managers to make decisions. With this research, it is hoped that it can help store managers in making decisions for determining clothing orders so that they can produce the best decisions that can provide benefits in the business that is being undertaken.

Abstract

The current online learning process requires virtual face-to-face media to interact between lecturers and students. However, currently available media requires lecturers to pay a fee to communicate indefinitely. Therefore, we need a media that can facilitate lecturers to do learning easily. This study aims to integrate jitsi with matrix conferences as a real-time online communication medium in learning. This type of research is development research (R&D) with the waterfall method. The steps taken are analysis, design, coding and testing. The analysis is carried out on the system development needs, then the design stage of the Jitsi architecture with a matrix, then coding using PHP and testing through QoS. QoS testing has very good throughput results, poor packet loss, very good delay, and excellent jitter for small-scale applications. It shows that picking video conferencing can be used as a medium of communication in online learning.

Abstract

This research was motivated by the confusion of students looking for title references for students' final assignments due to several obstacles, one of which was the lack of information about titles that had been done on their campus. The thesis catalog used in the library of the South Tapanuli Education Institute (IPTS) still uses printed media in one document in each department so that students have to take turns reading the catalog or students can directly look for theses one by one in the thesis cabinet or shelf and the current system is not yet running. using a database so as to allow the loss of the alumni thesis title data recap. So this is the background for the author to design a Thesis Catalog System by implementing a brute force algorithm in the process of searching for the title of the thesis. This thesis catalog system is a system that aims to facilitate the performance of library staff in inputting data, especially making it easier for students to find title references. The method that the author uses in this research is the development of R&D with the ADDIE model. In addition, the author also uses the SDLC development model while the model that the author uses in this study is the Waterfall model. The programming language used is the PHP language assisted by the MySQL database. Based on the results of the research that the author did, based on the validity test of 3 experts obtained a value of 0.80 Valid criteria, for the practicality test of 2 practitioners obtained a value of 0.889 very practical criteria and the effectiveness test of 10 students obtained a value of 0.871 very effective criteria, so that the value obtained proves that the thesis catalog system can help and is ready to use.
