In the digital era, the use of information technology in schools is essential to support more effective teaching and learning activities. SMP Negeri 16 Jakarta has implemented a digital-based library information system to replace manual methods. This system was evaluated using the PIECES method, covering six main aspects: Performance, Information Quality, Cost Efficiency, Security Control, Resource Efficiency, and Service Quality. The evaluation results showed that each aspect achieved good ratings, with average system performance at 34.6%, information quality at 39.9%, cost efficiency at 32.5%, security control at 37.7%, resource efficiency at 34.6%, and service quality at 33.8%. This evaluation indicates that the library information system at SMP Negeri 16 Jakarta is functioning effectively and efficiently. However, regular evaluations and system enhancements are necessary to ensure that the system continues to meet the library’s and users’ needs in the future.

This research analyzes the performance of the Academic Information System (SIAKAD) in supporting student tuition payments at STMIK Widuri using the PIECES method (Performance, Information, Economy, Control, Efficiency, Service). SIAKAD aims to streamline academic administration and enable online payments. However, issues such as system access delays, especially near payment deadlines, still occur, negatively impacting students' academic services and resulting in administrative penalties. The study employed data collection techniques through observation, interviews, questionnaires, and literature review. The PIECES framework was applied to evaluate six key indicators: performance, information, economy, control, efficiency, and service. The findings reveal that all indicators achieved an average score above 3.80, indicating a "good" system performance. Nonetheless, further improvements are necessary, particularly in terms of access speed and data security, to minimize user difficulties. The study concludes that optimizing the SIAKAD system is crucial for achieving effective and efficient payment processes. Recommendations include enhancing service quality, improving information accuracy, and strengthening data security. This optimization is expected to increase user satisfaction and support the institution's financial management stability.

An information system is a series that includes aspects of software, hardware and brainware in a structured manner with performance in a process that is interconnected so as to create a certain desired product, then the development of website-based system infrastructure can make it easier to data warehouse electronic products for both incoming and outgoing goods. for the admin, however, from the ongoing data warehouse process there are several problematic factors that influence it, namely, electronic product warehouse data collection for incoming and outgoing goods still uses a simple Microsoft Excel format which takes a long time and there are many warehouse data collection archives on computer storage as reports so it is vulnerable to viruses.

Azhari Bakar Bread Factory is an MSME domiciled in Rejowinangun, Kotagede, Yogyakarta. In the production process, this factory can produce 7807 pieces of bread in a month, of the total production that month 57 pieces of bread are defective. To reduce defects, quality control is needed. Quality control aims to produce products in the form of goods or services that comply with the desired and planned standards, as well as improve the quality of products that do not comply with predetermined standards and possibly maintain appropriate quality. This research uses the Six Sigma and Kaizen methods by showing factual data and comparing it with existing theories to find things that need to be added, improved, or maintained. This research found that the sigma process capability calculated for 1 month was 2.97 with a possible damage of 3661.21 for one million production. From these results, it can be said that the company has not implemented quality control completely properly and correctly because it is still far from the target level of 6 sigma, therefore the company needs to carry out quality control on defective products. The factor that causes production defects is the human factor. machines, methods, materials, and environment.
