The split attribute in the decision tree algorithm, especially C4.5, has an important influence in producing a decision tree performance that has high predictive performance. This study aims to perform an attribute split in the C4.5 algorithm using the value of the termination coefficient (R2/R Square) which is combined with the aim of increasing the performance of the model performance produced by the C4.5 algorithm itself. The data used in this research are public datasets and private datasets. This study combines the C4.5 algorithm developed by Quinlan. The results in this study indicate that the use of the R2 value in the C4.5 algorithm has good performance in terms of accuracy and recall because three of the four datasets used have a higher value than the C4.5 algorithm without R2. Whereas in the aspect of precision, it has quite good performance because only two datasets have a higher value than the performance results of the algorithm without R2.
Badan Permusyawaratan Desa atau yang disingkat BPD ialah lembaga yang mengoptimalkan penyelenggaraan pemerintahan Desa dan bekerja sama atau sebagai mitra kerja Kepala desa. Anggota-anggota BPD merupakan perwakilan dari masyarakat desa yang dipilih dengan cara demokrasi. Penelitian ini menggunakan metode deskriptif dengan pendekatan kulitatif. Teknik pengumpulan data dilakukan dengan studi pustaka, observasi, wawancara dan dokumentasi. Data diambil darai narasumber yang ditetapkan berdasarkan teknik data display. Hasil penelitan menunjukan bahwa kinerja BPD dalam melaksanakan fungsi yang pertama yaitu membahas dan menyepakati rancangan peraturan desa bersama kepala desa, telah dilaksanakan sesuai dengan fungsinya. Sedangkan, dalam melaksanakan fungsi yang kedua yaitu menampung dan menyalurkan aspirasi masyarakat desa, telah dilaksanakan sesuai dengan fungsinya namun masih terdapat kendala. Berdasarkan hasil penelitian, terlihat bahwa BPD Desa Sukalaksana telah melaksanakan fungsinya namun masih terdapat kendala dan belum optimal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
