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.

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.

The heavy equipment business in Indonesia is again excited in line with the increasing demand for heavy equipment by various sectors such as the mining sector, the agro-industry sector, and the construction sector. PT. Petronesia Benimel is one of the business fields engaged in renting heavy equipment. The management of the heavy equipment rental schedule to other companies has been carried out using a computerized system, namely using the Microsoft Excel application which is still not optimal in integrating, calling and processing data at once. Using these applications independently results in the management of heavy equipment rental reports being constrained because tenant data and rental management are often out of sync. The application uses Visual Basic programming language and MySQL database supported by research and product development methods and waterfall development models. Based on the trial results of using a schedule report application that can make it easier for staff to manage heavy unit rental schedules from various partner companies (stakeholders) so that better reports are obtained.

PT. Rifansi Dwi Putra is a company that operates in the Oil and Gas Industry, especially in the Waste Handling Transportation (WHT) Project regarding Waste Transportation. PT. Rifansi Dwi Putra especially at the Sand Management Facility (SMF) in processing waste volume data already uses a computer and is supported by Microsoft Excel software. However, doing data input, searching, processing, and reporting takes a relatively long time. So that the resulting information is less accurate, thus requests for fast and accurate information are often late in presenting their reports. In this regard, to facilitate the process of data accuracy, it is better to create an application for data collection of waste volumes using Visual Basic Programming Language and MySQL database. To facilitate the operations department, especially in recording the volume of waste transported to the Sand Management Facility (SMF) and making reports on the volume of waste to control, repair, and process data based on information technology and help the obstacles faced. To produce applications in waste volume data collection to facilitate structured data input in the data entry process, make it easier to search waste volume data, and help the management team produce accurate waste volume reports, making it easier to make decisions. The user of this application is only owned by one person because it is still a single user or stand alone (desktop-based) and this application produces three reports, namely reports per day, reports per month and reports per unit.
