Abstrak - Website Pondok Modern Nurul Hidayah berfungsi sebagai sarana utama informasi dan komunikasi antara lembaga Pendidikan dan Masyarakat. Namun, belum tersedia dokumentasi sistematis mengenai kualitas kode perangkat lunak. Penelitian ini bertujian menguji kualitas kode website tersebut menggunakan standar internasional ISO 5055, yang mencakup empat aspek: keamanan, keandalan, efisiensi kinerja, dan kemudahan pemeliharaan. Metode yang digunakan adalah Software Testing Life Cycle (STLC), dengan alat bantu seperti SQLMap, PHPUnit, PHP CodeSniffer, dan PHP Metrics. Hasil pengujian menunjukkan bahwa sistem cukup efektif menahan serangan SQL Injection, meskipun terdapat celah autentikasi pada halaman formulir. Dari sisi keandalan, seluruh unit berhasil di uji tapa kesalahan fatal, namun terdapat peringatan deprecation. Efisiensi kinerja terhambat oleh pelanggaran standar PSR-12 seperti penamaan dan visibilitas metode. Nilai kompkeksitas kode yang tinggi (Cyclomatic Complexity = 23.34) mengindikasi Tingkat maintainability yang rendah. Dengan skor rata-rata 68.75 dari empat aspek, disimpulkan bahwa meskipun sistem memiliki pondasi teknis yang baik, dibutuhkan refactoring dan penerapan standar penulisan kode yang konsisten untuk peningkatan berkelanjutan. Penelitian ini juga menyajikan kerangka pengujian praktis berbasis open-source yang dapat diadopsi institusi Pendidikan berskala kecil.

The coffee shop industry in Indonesia is experiencing rapid growth, including D'Kopikap as one of the businesses facing challenges in managing production and inventory. The main difficulty lies in the uncertainty in predicting the number of sales, which is influenced by various factors such as the type of day (weekdays, weekends, holidays, and promo days) and the time of sale. To overcome this problem, a sales prediction system using multiple linear regression algorithm was developed. System development is carried out using the Rapid Application Development (RAD) approach to accelerate the design and implementation process. The data used in this research is divided into two parts, namely training and test data of 80:20. The results showed that the sales prediction system created was able to provide sales forecasts that could be used to assist production planning and inventory management. Evaluation of the model shows the Root Mean Squared Error (RMSE) value of 22.48, Mean Absolute Percentage Error (MAPE) of 37.18%, and Coefficient of Determination (R²) of 72.26%. These results indicate that the model has good enough predictive ability to be used in operational activities. This research is expected to be the basis for the development of a better sales prediction system in the future.

The performance evaluation of student organizations (Ormawa) at Politeknik Negeri Bengkalis is an essential part of the end-of-term management assessment, serving as a form of accountability and a basis for future development. The manual process used so far often takes considerable time and is prone to errors. To address this issue, a web-based decision support system was developed using the Multi-Factor Evaluation Process (MFEP) method, which applies a weighting system in the decision-making process. The system was developed using the Rapid Application Development (RAD) approach, enabling a fast and efficient development process through a linear and sequential methodology. The implementation of the MFEP method in the system achieved an accuracy rate of 88.88%, based on a comparison between field data and system processing results.
