ABSTRAK Kitab suci Al Quran terdiri dari 114 surat. Masing-masing surat memiliki jumlah ayat yang berbeda. Ayat-ayat tersebut ada yang panjang dan ada yang pendek. Banyak atau sedikit jumlah ayat dalam suatu surat, dan panjang atau pendek ayat memberi pengaruh terhadap lama waktu membaca surat-surat dalam Al Quran. Penelitian ini bertujuan untuk melakukan pengelompokan (clustering) surat-surat dalam Al Quran berdasarkan jumlah ayat, jumlah ruku dan lama waktu membaca surat. Algoritma clustering yang digunakan adalah K-means. Dari percobaan yang dilakukan, nilai optimal diperoleh pada iterasi ke-14 dengan nilai k sebanyak 4 cluster. Cluster_0 terdiri dari 18 anggota dengan nilai centroid pada variabel ayat sebesar 106,389, variabel ruku sebesar 9,778, dan variabel lama sebesar 1333,5. Cluster_1 terdiri dari 26 anggota dengan nilai centroid pada variabel ayat sebesar 62,038, variabel ruku sebesar 4,885, dan variabel lama sebesar 662,5. Cluster_2 memiliki 7 anggota dengan nilai centroid pada variabel ayat sebesar 183,143, variabel ruku sebesar 22,857 dan variabel lama sebesar 3310,571. Sedangkan cluster_3 memiliki 63 anggota dengan nilai centroid pada variabel ayat sebesar 22,635, variabel ruku sebesar 1,508, dan variabel lama sebesar 145,635. Kata kunci: Clustering, K-means, Al Quran.
The concept of e-learning provides more intensive interaction between lecturers and students, students and students, both in the classroom and outside. E-learning can increase student interest in optimizing the potential of multiple intelligences. Incorporating Multiple Intelligences into e-learning strategies provides a level of flexibility in how students can carry out their learning and provide a collaborative and interactive environment. This study aims to analyze student activity in e-learning based on multiple intelligences. The method used is descriptive qualitative by analyzing student activities in e-learning based on the classification of 8 Multiple Intelligences. The results of this study stated the percentage of students based on multiple intelligences obtained the highest percentage value of 38% Naturalist intelligence, 24% Musical intelligence, 17% Visual Spatial intelligence, Logic mathematical intelligence and Interpersonal intelligence 7%, Kinesthetic intelligence 4%, Intrapersonal intelligence 3%, and Linguistic intelligence 0%. Analysis of e-learning activities obtained the highest frequency by visua-spatial intelligence with a percentage of 82%, dominant naturalist intelligence possessed by students in the class has a percentage of 74%, then intrapersonal intelligence as much as 63%, kinestetic intelligence 53%, interpersonal intelligence 47%, musical intelligence 31%, and logic-mathematic intelligence 29%. Because in this class the dominant type of naturalist intelligence, e-learning is declared suitable to be applied because this intelligence is included in the active category of activities in e-learning.
Pendidikan keluarga merupakan Lembaga Pendidikan yang pertama, proses pembentukan karakter-karakter terjadi akibat dari pembiasaan. Pembentukan kebiasaan akan lebih efektif bila didukung oleh sosok teladan yang dapat dijadikan panutan dalam kehidupan keluarga. Tujuan penelitian ini adalah untuk mendeskripsikan tentang pembentukan karakter gemar membaca, karakter religius dan tanggung jawab pada anak usia sekolah dasar. Metode penelitian menggunakan pendekatan deskriptif kuantitatif. Teknik pengumpulan data dilakukan dengan menggunakan Teknik non tes. Bentuk instrument yang digunakan berupa lembar observasi atau kuesioner. Populasi dalam penelitian ini merupakan anak-anak usia SD di lingkungan komplek perumahan kavling DPU Singocandi Kota Kudus dengan jumlah 12 orang. Alat ukur atau variable yang digunakan yaitu skala karakter religius, karakter gemar membaca, dan karakter tanggung jawab. Hasil penelitian ini yaitu karakter religius pada anak SD tergolong cukup tinggi. Untuk karakter gemar membaca sendiri masih tergolong sedang. Sedangkan untuk karakter tanggung jawab pada anak SD sudah tergolong tinggi.
Cryptography is a method of securing text data, images and sound in order to secure its confidentiality and to minimize data stealing, attack, etc. The purpose of this study is to improve classic Vigenere cipher using bit circular shift on image encryption. This experiment uses both RGB and grayscale images as samples and shows that Vigenere cipher with bit circular shift has better performance when encrypting an image both visually and its randomness. It is obtained the MAE values of images of final encryption process are 81.702637 of RGB and 73.678756 of grayscale, and the final decryption process of 0 for both images. The randomness of images of the final encryption process is shown by its correlation coefficient values; it is 0.033857 of RGB and -0.058501 of grayscale.
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.
