Abstract

Abstrak Program Indonesia Pintar (PIP) merupakan salah satu kebijakan pemerintah yang diharapkan dapat meningkatkan aksesibilitas dan pemerataan pendidikan di Indonesia, namun dalam pelaksanaannya pemberian beasiswa dari program ini masih dijumpai banyak kasus yang kurang tepat sasaran. Salah satu permasalahannya adalah masih ditemukan siswa penerima bantuan pendidikan yang berasal dari keluarga yang mampu, sedangkan siswa yang kurang mampu justru tidak mendapatkan bantuan. Sehingga diperlukan suatu sistem klasifikasi berbasis web yang dapat mengklasifikasikan siswa layak atau tidak untuk mendapatkan PIP. Penelitian ini mengimplementasikan algoritma -nearest neighbor untuk mengklasifikasikan siswa penerima beasiswa PIP. Penelitian ini menggunakan data siswa/i SMAN 1 Sinunukan, Mandailing Natal yang didapat melalui penyebaran angket sesuai dengan kriteria yang telah ditentukan. Data yang telah diperoleh kemudian dilakukan preprocessing data dengan menggunakan Label Encoder dan Normalisasi Min-Max. Data dibagi menjadi dua jenis yaitu data training dan data testing. -fold cross validation digunakan untuk menentukan nilai yang optimal. Hasil penelitian ini memperlihatkan tingkat akurasi yang dihasilkan berdasarkan hasil pengujian yang dilakukan untuk implentasi algoritma -nearest neighbor dalam klasifikasi kelayakan penerima beasiswa PIP yaitu sebesar 70% dengan nilai .

Abstract

Student learning outcomes are still low due to the low ability of teachers to utilize learning media in the learning process. This makes it increasingly difficult for students to understand the material presented by the teacher, because they become less active and pay less attention to the teacher's explanation of the material presented. This research formulates the question of whether the use of statistics whiteboard media in statistics teaching materials at SMA Negeri 1 Rao Class XII IPA 1 SMA Negeri 1 Rao in mathematics education can improve student learning outcomes. The approach used in this research is classroom action research (PTK) using the Kurt Lewin model which consists of the stages of planning, taking action, observing and reflecting. The subjects of this research were students of Class XII Science 1 SMA Negeri 1 Rao. The data collection tools used are observation to observe student activities and teacher tests to measure student learning outcomes, interviews to collect data, and data collection on statistical board media.
