The evolution of software is necessary for the success of software systems. Studying the evolution of software and understanding it is a vocal topic of study in software engineering. One of the primary concepts of software evolution is that the internal quality of a software system declines when it evolves. In this paper, the method of evolution of the internal quality of object-oriented open-source software systems has been examined by applying a software metric approach. More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.

Website Pengurus Cabang Nahdlatul Ulama (PCNU) Depok dibuat sebagai sarana penyimpanan dan pengelolaan data dalam organisasi tersebut. Penelitian ini bertujuan untuk mengukur kualitas website PCNU Depok dilihat dari maintainability, flexibility dan testability. Tahapan penelitian yang dilakukan : analisis modul website, instalasi website PCNU, instalasi composer, instalasi PHPMetrics, menjalankan aplikasi PHPMetrics untuk mengukur kualitas website PCNU, menganalisis hasil pengukuran dari PHPMetrics.Penelitian kualitas website dengan metode maintainability index mehasilkan nilai 63,57 yang diklasifikasikan sebagai low maintainability. Low maintainibility index berdampak kepada lemahnya modul website untuk dilakukan perawatan dan pengembangan berdasarkan Lines Of Code, Cyclomatic Complexity, dan Halstead Volume. Faktor flexibility, website mendapatkan klasifikasi moderate atau batas wajar karena memiliki coupling = cohesion. Testability pada website memiliki klasifikasi baik dengan nilai rata-rata 16,65. Dengan nilai testability baik website mendapatkan nilai positip pada proses testing dan maintenance sehingga modul tidak sulit untuk dimengerti dan dikembangkan.
