Abstract

Conditions of intense competition, especially in Batam and in the hospitality sector, there are several hotels in Batam that use a Web-based OYO information system. Where OYO collaborates with property owners who do not yet have a hotel management system, where OYO task is to control and develop hotel management then connect and market it through the OYO application to make it more accessible online. The technique used is by distributing questionnaires orally to respondents with 25 questions and a sample of 115 respondents.The use of the measuring instrument is 5 points Likert scale. Using descriptive analysis for data analysis methods, Using validity and reliability test for the data quality test, then there is a classical assumption test using normality and heteroscedasticity tests, and hypothesis test using T and F tests with help of statistical software SPSS 20. Based on the results that the variables of Usability, Information Quality, Interaction Quality all three have a positive influence and also have a significant influence on the Website Quality.

Abstract

In today's era, human daily activities cannot be separated from the use of technology. One of them is business activities. PT Dharma Sentosa Marindo is a company engaged in the shipyard industry. So far, the attendance administration records at PT Dharma Sentosa Marindo still use paper media which are then processed and stored on a computer manually. This makes the attendance process slower and less accurate, causing delays in generating attendance reports. This study aims to design an attendance information system at PT Dharma Sentosa Marindo to increase the speed and accuracy of recording attendance administration at PT Dharma Sentosa Marindo. The system design method uses the scrum method which uses the principles of agile development methodology. The results of system testing using the blackbox testing method show that the designed system has run smoothly and as expected

Abstract

In Indonesia, badminton is one of the most popular sports among the people, where every competition on the world stage, Indonesian people flock to watch every match and it is not uncommon for athletes from Indonesia to win in every competition. In the era of the development of information technology, especially information systems, there are still many badminton courts that still use field reservations using the manual method by taking notes on paper, ordering by telephone or WA, and so on. This can pose a risk of loss of ordering data during the recording process. For this reason, this research creates a web-based application to solve the problem of renting a badminton court in Batam City. This web-based application is created using the extreme programming method with the PHP and HTML programming languages. The purpose of this research is to make it easier for tenants to make bookings on badminton courts and make it easier for managers to collect data by utilizing the existing internet network.

Abstract

The selection of outstanding students at MIS Imadun Ghoffar went through a long and complicated process. The selection process has the opportunity to make wrong decisions in the selection process, because the student selection process is based on subjectivity, which means that the selected outstanding students will most likely not reach the desired level and will not get the best candidate. Therefore, a decision support system is created that can calculate all the criteria for selecting outstanding students. In this work, the SAW (Simple Additive Weighting) method is implemented. This method makes decision making easier. The problem to be solved is divided into several elements, namely Criteria. The criteria needed are the average value of report cards, extracurricular scores, attitude scores and absences. The results of this system are expected to produce outstanding students according to the specified criteria. From this it can be concluded that the decision support system for selecting outstanding students at MI Imadun Ghoffar can be a solution or consideration in selecting outstanding students.

Abstract

Attendance is an important factor for an institution, especially in the field of education, in order to achieve goals related to student discipline.There are many ways to improve the attendance information system to make it better, one of which is by using computer technology through a website-based integrated attendance system. At the MSI Imadun Ghoffar Batam school, currently they still use the manual method in the attendance system, namely by recording student attendance using a book. This method is less efficient because if the attendance book is lost or exposed to water, it will inconvenience the school and harm students. In addition, the risk of errors and loss of attendance data is also greater.Based on the problems above, we have created an attendance system at MSI Imadun Ghoffar that is integrated web-based. This system is used by parents and homeroom teachers respectively. The research method used in data collection is research and library methods. Software development uses the waterfall method. By using an integrated web-based attendance system, the attendance process, data search, and attendance recap calculations are made easier and also minimize loss and errors in recording attendance data.

Abstract

The employee management information system at Nazra Swim School (NSS) was created with the aim of improving the performance and service of employees at Nazra Swim School (NSS). Nazra Swim School has a lot of data, one of which is employee data that needs to be stored and processed. Employee data processing is currently still done manually. To facilitate the processing of employee data, an information system is needed to process employee data so that the resulting information is more accurate, efficient and precise. This employee management information system is done using the waterfall method. This information system design includes document flowcharts, system flowcharts, data flow diagrams, context diagrams, database design, conceptual data model (CDM), physical data model (PDM) and user interface design. The employee management information system is designed using the programming language PHP, Notepad++ and MySQL database. implementation of a web-based employee management information system can help administration and employees in managing employee data automatically.
