Abstract

Abstrak :  Penunggakan iuran sekolah menjadi salah satu permasalahan yang ada pada setiap sekolah ataupun institusi pendidikan lainnya. Salah satu sekolah di Karawang mengalami masalah yang sama dalam penunggakan iuran sekolah yang dilakukan oleh para siswanya. Sekolah tersebut mengalami sejumlah kerugian akibat tunggakan ini. Terhambatnya proses administrasi sekolah akan terjadi dan pihak sekolah harus memiliki strategi untuk menanganinya. Maka dari itu, penelitian ini melakukan klasifikasi terhadap siswa yang akan melakukan tunggakan dengan mengimplementasikan algoritma Naïve Bayes dan hasilnya diterapkan ke dalam sebuah sistem berbasis website. Penelitian ini menggunakan metodologi KDD yang sering digunakan untuk olah data mining. Pada perhitungan pengujian diterapkan skenario pembagian data training dan data testing menggunakan percentage split guna mencari pemodelan mana yang menghasilkan kinerja optimal. Hasil akhir pemodelan menghasilkan rasio pembagian 50:50 memiliki hasil yang terbaik dengan nilai Akurasi sebesar 85.461%, nilai Presisi sebesar 0.869, nilai Recall sebesar 0.855 dan nilai F-Measure sebesar 0.857. Sistem berbasis website dibangun sebagai hasil akhir diuji menggunakan Black Box Testing dengan metode Boundary Value Analysis yang hasilnya menunjukkan tiga skenario uji berhasil dilakukan pada semua elemen field sistem yang ditandai dengan keterangan “Success” pada kesimpulan._______________________________Abstract :Arrears school tuition are one of the problems that exist in every school or other educational institution. One of schools in Karawang also experienced the same problem in context of arrears school tuition by its students. This school suffered from all students in many of arrears. Obstructed of school administration process will occur and the school must have a strategy to handle it. Therefore, this research classifies students who will do arrears by implementing the Naïve Bayes algorithm and the results are applied into a website for arrears school tuition. This research uses KDD methodology which is often used for data mining process. In the test calculations, scenario for split training data and testing data using a percentage split technique was carried out to find which modeling produces optimal performance. The final result of modeling produces a split ratio of 50:50 has the best results with an accuracy score of 85.461%, a precision score of 0.869, a recall score of 0.855 and a F-Measure score of 0.857. This website is built as the final result and tested using black box testing with the Boundary Value Analysis method, the results show that three test scenarios were successfully carried out on all elements of the system field which are marked with the description "Success" at the conclusion.

Abstract

Every technology device these days should have a lot of components which support the performance of the devices, one of the components is Universal Serial Bus or known as USB. USB is a communication protocol on a device that can be use as a connection between devices. There's a lot of type from USB it self, such as USB type A and USB type C, and both have their own capabilities. We can find USB type A are still used this time especially on smartphones, but slowly we can feel the impact of appearence of USB type C is can shift the position of USB A because of its superior ability compared to USB A. According to that, it have been tested between cables with USB A connector and USB C connector with experimental research to find out the quality of USB as seen from the transfer rates of the two types of USB. The result of the experiment, explains that USB cable with type A connector is faster than USB type C. Results of the experiment are inversely proportional to the theory because of many factors that influence.
