Abstract

The initial research purposes is to do the analyzing of data transaction for one of the stationary stores in Batam city, namely edukits Batam Centre, because the store is a well-known business and of course many consumers are interested, of course, a lot of data has been collected so far. From transactions that have occurred so far, these data are only stored in the form of archive files without being processed or used for future business progress. To analyze this research, the a priori algorithm association rule method was used, by analysing support value and as well as the confidence value that were set so that the results of this study obtained the support value for the Printing Paper category 71%, Accessories 74%, 77%, Other Equipment 88%, Glue and Adhesive 72%. By using the Apriori algorithm, 2 rules are obtained, namely the antecedent value of stationery, the consequent accessories resulting in a support value of 65% and confidence of 84.4%. Then the second rule is the antecedent of accessories, the consequent of writing instruments with a support value of 65% and a confidence value of 88.4%.

Abstract

The purpose of making the Design and Development of a Website-Based Ranoh Island Tourism Management Information System is to promote and facilitate booking of tour packages on Ranoh Island. Web-based visual information system is a system consisting of text and graphic images. It is these factors that make these tours interesting and make bookings easy. In addition, the Website-Based Ranoh Island Tourism Management Information System is a system that contains complete information for tourists and can be found at any time. This support cannot be separated from the research process design and technology. This study aims to design a Website-Based Ranoh Island Tourism Management Information System as a source of information for viewing and ordering tourist attractions and other facilities on Ranoh Island. The Website-Based Ranoh Island Tourism Management Information System was developed using the PHP programming language and data stored in a database using MySQL to optimize system and database performance. The Google Maps API is one of the features of this information system that can be used to add maps to websites using JavaScript. The result of the design is a web tourism information system which should be a way to promote tourism in the city of Batam, so that through this web design it is hoped that there will be a similar system to create better services. and more complete than existing services.

Abstract

LPG gas is one of the most needed fuel sources today, especially for household cooking needs. The need for this type of fuel increases every day, month, even year in accordance with the addition of members in the family itself. The increasing consumption of LPG gas in the community cannot be separated from the need for LPG gas which is expected to continue to increase, as well as the country's population which is growing at a rate of 1.49% annually. PT Dinamika Purnakarya Persada is an authorized agent of non-subsidized LPG gas in Batam City. Where this PT is engaged in the distribution and sale of Bright Gas Non Subsidized. From the results of a survey conducted previously, the problem so far is when the LPG gas situation is scarce, making it difficult to meet customer demand. As a result, sales at PT Dinamika Purnakarya Persada decreased, causing disappointment to customers. To overcome the above problems, the authors will apply the Least Square Method as a strategy commonly used to predict sales. This approach is a system in the form of periodic or time series data, in which some historical sales data is needed to estimate sales results in the following years. By looking at historical data, sales transactions are in the months of January to December 2024 for 50KG gas cylinders, as well as 12KG cylinders, while for 5.5KG gas cylinders are in January 2024.

Abstract

The rapid advancement of technology is driving digital transformation across various sectors of life, including the business world. PT Weefer Indonesia, as a company focusing on digital transformation, plays a crucial role in the effective implementation of information technology. Particularly since the Covid-19 pandemic, the company has adopted a hybrid work model with the support of the Lark Suite application. Lark Suite serves as a team collaboration tool, providing a messaging platform, video conferencing, and a calendar to facilitate internal and external communication. This research aims to measure the maturity level of the Lark Suite application during its usage at PT Weefer Indonesia using the COBIT 5.0 framework. COBIT 5.0, as a comprehensive management guide, provides a foundation for analyzing system performance. Based on previous research conducted by other scholars using the COBIT 5.0 framework, its effectiveness in identifying the maturity level of information systems has been proven. The use of COBIT 5 is expected to provide in-depth insights into the maturity level of the application and identify areas that can be enhanced or developed to improve the efficiency and effectiveness of team collaboration. This research is anticipated to contribute positively to the company in understanding and enhancing the utilization of the adopted collaboration application.

Abstract

The Batam Madani Fishermen's Cooperative is a business that markets equipment, namely equipment for fishing, including fishing rods, hooks, floats, winches, bait and others. With the increasingly complex development of the fishing equipment business, this business requires a computerized system for marketing its fishing equipment. The Batam Madani Fishermen's Cooperative, which until now is still marketing fishing equipment manually, is the process of recording it in a ledger and inputting it into the Microsoft Excel application, which often creates difficulties in providing information in the form of reports on the types of fishing equipment and incoming fishing equipment, fishing equipment that has not been sold, and stock records by interested parties. Another visible satisfaction is that buyers can only view or order goods by coming directly to the Fishermen's Cooperative or by looking at brochures distributed to several areas. However, these methods are considered inefficient for buyers who are far from cooperative. Therefore, a new Information System is needed that can facilitate the marketing of fishing equipment.
