Manual inventory management at Toko Terang Abadi presents various challenges, including delays in reporting and high recording errors. This study aims to improve accuracy and efficiency in stock management by creating a web-based inventory information system using the Waterfall method. Data collection was conducted through interviews, direct observation of store activities, and literature review. The system was designed and implemented using PHP and MySQL, and tested using black-box testing methods to ensure all functions work according to user needs. Implementation results show that recording efficiency increased by 50% and input errors decreased by 90%. These findings support previous research highlighting the importance of digitalizing inventory systems in the SME and retail sectors to improve effectiveness and accuracy in managerial decision-making.

Abstract. A store requires an effective and efficient accounting information system to manage its finances, ensuring business continuity and financial sustainability. One such case is Am Collection Store, which has not yet adopted computer technology. The store still uses manual methods for cash receipts processing.

In the era of increasingly advanced technological development, decision support systems (DSS) play an important role in improving the quality of decision-making in the education sector. The selection staff at SMP Dharma Bakti find it difficult to objectively determine the best academic students because they still use a manual method that is prone to errors. This research aims to design a web-based decision support system that can help selection staff assess and determine their best academic students objectively and quickly. This system is developed using the PHP programming language, MySQL database, LARAVEL 8 framework, and applies the Analytical Hierarchy Process (AHP) method within it. This research produces a system that allows the SMP Dharma Bakti Selection Officers to input alternative data, namely student data, determine the weight of criteria and sub-criteria, and view the ranking results automatically, thus greatly facilitating the SMP Dharma Bakti Selection Officers in determining their best academic students.

The rapid development of information and communication technology has opened up significant opportunities to enhance service efficiency in various fields, including the beauty industry. Soraaya Studio, which offers a range of beauty services, currently still manages appointment scheduling manually. This manual system leads to several challenges, such as difficulties in efficient schedule management, data duplication, recording errors, and disorganization in the service reservation process.

The manufacturing industry faces major challenges in maintaining consistent product quality amidst the dynamics of technology and global competition. This study aims to develop an effective Business Intelligence (BI) implementation model to support data-based quality control. The method used is a conceptual design approach through integrated system simulation, including MySQL database, PHP backend, Power BI visualization, Google Cloud AutoML predictive analytics, and initial processing using Microsoft Excel. Historical production data for 12 months is used for model training and defect trend visualization. The simulation results show that the implementation of BI can reduce product defect rates, accelerate system response, and increase inspection process efficiency. Technical validation proves the model's prediction accuracy is above 90%, while field validation shows positive acceptance from users regarding the ease of use of the dashboard. This system not only supports early detection of quality deviations but also contributes to real-time strategic decision making. With an integrated technology approach, BI enables medium-sized manufacturing companies to adopt an adaptive and sustainable digital quality system, in line with the concept of Quality 4.0.

This study aims to design and implement a web-based outpatient registration information system at Regional General Hospital (RSUD) X to overcome issues arising from the manual registration system. The current manual registration system at RSUD X causes problems such as long queues, potential data entry errors, lost files, and difficulty in finding patient medical history. As a result, patient waiting times are longer, the administrative staff's workload increases, and the overall effectiveness of services decreases. The research method used is a qualitative one, which describes various processes in the system, from patient data input to the digital registration receipt output. The system design approach uses the waterfall method. Data collection was carried out through purposive sampling, while data gathering was done through interviews with registration officers, direct observation, and a documentation study in the medical records unit. The system is built with a combination of technologies, including PHP as a server-side programming language and MySQL as the database. The result is a web-based outpatient registration information system that can improve the efficiency and quality of hospital services. The advantages of this system include wide accessibility, time efficiency, and effective data management. This system is expected to reduce patient queues, improve the efficiency of the registration process, and simplify patient data management. However, the implementation of this system may face challenges such as limited resources and user skills. Solutions to overcome these challenges are effective resource allocation and user training. Overall, the web-based outpatient registration information system can be an effective solution to improve service quality at RSUD X.

This research aims to address the challenges in sales data management and limited market reach faced by the Inegena Village-Owned Enterprise (BUMDes) in North Bajawa District, Ngada Regency, East Nusa Tenggara. The BUMDes produces and sells candlenut oil, a superior local product, but currently uses a manual sales and recording system (B2B and B2C), which leads to fluctuating demand, difficulties in sales data analysis, and decision-making that lacks valid data. To address these issues, a web-based e-commerce system was implemented. This system was designed using Agile methods, involving planning, implementation, software testing (black box testing), documentation, deployment, and maintenance. Furthermore, the Naïve Bayes algorithm was applied to visualize sales data and support better decision-making by classifying best-selling products, popular payment methods, and sales levels. The results of this research are expected to assist Inegena BUMDes in improving sales efficiency, expanding the market reach of candlenut oil products nationally. This system uses supporting software such as Xampp, PHP, and MySQL.
