The advancement of technology has significantly facilitated various aspects of human life, including business, health, education, and more. One such technological application is the use of computer-based inventory management systems that streamline data management processes, from recording to quick and accurate data retrieval, while also monitoring assets. PT. SAC Nusantara, established in 1971, faces challenges in its Bandar Lampung branch, where inventory management is still done manually, leading to slow data input, frequent errors in stock calculations, and delayed reporting. To address these issues, a computerized inventory management system is needed to improve efficiency, accuracy, and monitoring. This study aims to design, build, and develop a web-based inventory management system to replace the manual processes. The research utilizes the Framework for the Applications of System Thinking (FAST) method, which is flexible and allows for rapid development with user involvement in each stage. The system is designed to automate the recording and reporting process, reduce errors, and improve real-time inventory tracking. The FAST method, along with Data Flow Diagram (DFD) and Entity Relationship Diagram (ERD), will be used to analyze and design the system. The system's functionalities, such as item entry, exit records, and reporting, are evaluated through black-box testing. The expected outcome of this research is a web-based inventory management system that increases the efficiency and effectiveness of inventory management, providing accurate and timely data that will support decision-making processes. The findings indicate that the implementation of this system will significantly improve inventory handling at PT. SAC Nusantara's Bandar Lampung branch.

SM Wedding Decoration is a place that provides services to take care of everything related to weddings. For example, wedding decorations, wedding organizers, and wedding planners. SM Wedding Decoration has several wedding packages that can be offered to customers.  The large number of packages available makes prospective brides or customers confused about which wedding package is suitable for their wedding. The a priori algorithm method is used in this research to find recommendations for wedding packages based on existing transaction data and to improve company strategies and sales of other wedding packages. The Apriori algorithm is used to help computers learn patterns of association rules. This algorithm looks for a group of things that match the given criteria or order and have a certain frequency value. From this research, customers tend to order Photographer & Documentation and MUA ? Deluxe packages more often, and these orders account for 44% of all package order transaction data. Transaction data for ordering the MUA?Deluxe Package was 41.3%. Photographer & Documentation package transaction data ? Deluxe Package is 41.2%. And transaction data for ordering the MUA package ? Premium Deluxe Package is 41.3%.

This study aims to design a web-based interior ordering information system for PT Cipta Kreasi Buana, which has been operating since 2015. Currently, the process of ordering products and interior services is still conducted manually, which can lead to errors in order writing and a lack of transparency for customers. The method used in this research is the prototype method, which includes needs analysis, system design, application development, and evaluation. The primary focus of this system design is to create an intuitive and responsive user interface, making it easier for customers to place orders. The results of this study indicate that the implementation of the web-based ordering information system can enhance the efficiency and effectiveness of the company's operations. The designed application allows customers to place orders more easily and quickly, while also providing better management of orders and inventory. With this system in place, PT Cipta Kreasi Buana can improve customer satisfaction and keep up with digital technology advancements. This research is expected to serve as a reference for other companies in developing similar information systems.

The application of data mining in the evaluation of Hadrah tests at Pesantren Salafiyah Syafi'iyah is explored using the Random Forest algorithm. Hadrah, a form of Islamic artistic performance involving vocal and percussion elements, is integral to the cultural and spiritual life in Islamic boarding schools. The objective of this research is to enhance the accuracy and objectivity of performance assessments in Hadrah, particularly in the context of competition or educational evaluation at Pesantren Salafiyah Syafi'iyah. By utilizing the Random Forest method, which is a robust machine learning technique, the study aims to minimize the subjectivity and inconsistency inherent in traditional evaluation methods. The study leverages secondary data from previous Hadrah tests, applying preprocessing steps to ensure the data is suitable for analysis. The results show that Random Forest provides a high level of precision in classifying participants based on key assessment features such as tempo, consistency, and overall performance. This method contributes significantly to improving the reliability and fairness of the evaluation process, ensuring a more standardized approach to assessing artistic skills in the context of Islamic traditions. The findings suggest that data-driven approaches can play a pivotal role in preserving and promoting Islamic arts while enhancing the educational process.

The purpose of this study is to assist tourists in providing information on tourist services for the waterfall at the foot of Mount Salak, so as to produce precise and accurate information reports. The development method used in this research is the SDLC (System Development Life Cycle) system. SDLC System Development Method This SDLC method is a method with a system development and design process through several stages, starting from system planning to operation and maintenance. Data collection methods used in this study are: observation, interviews, and literature study. This research produces an application that can assist tourists in providing more accurate information on waterfall tourism services at the foot of Mount Salak.

Al Hikmah Semesta Cooperative, Pegandon Branch, is a savings and loans office that helps the community in terms of business financing, agricultural capital, savings in the form of deposits, a cooperative structure that provides loans to customers, interest rates on various credits, etc. Problems with the Al Hikmah Semesta Cooperative loan application system, Pegandon Branch. This system still uses a manual system where data is collected via the Excel application, which is of course vulnerable to data loss and damage. The information system of the Al Hikmah Semestah Community Cooperative Pegundon Branch will make the provision of financial information to users of financial reports more effective and precise. The success of the role of the information system can be measured from the effectiveness of presenting borrower data reports. If the loan application information system plays a good role in its implementation, this system can produce effective and high-quality borrower data reports that become the basis for decision making.

The research objective is to produce a gadget sales information system that can simplify the process of recording sales data to sales reports. According to observations and interviews that the author did at PT Kafilah Teknologi Indonesia in processing gadget sales data, all of which still use the manual method, namely recording in the books so that errors often occur. in calculating reporting and which often vary, this can hamper the process of financial reporting performance. The research method used in the Design of Gadget Sales Information Systems at PT. This Indonesian Technology Caravan is grounded research, which is a research method based on facts and using comparative analysis which aims to generalize epirisses, establish concepts, prove theories, and develop theories where data collection and data analysis run at the same time. In addition, the authors also conducted research with data collection methods by means of Observation, Interview and Documentation. After the author designed the Gadget Sales Information System, the author can help build a prototype so that the results are useful for the company so that it is expected to be more effective and accurate.
