Abstract

Suppose is any group and then the smallest subgroup of containing is the intersection of all subgroups of containing and denoted by . If then , such a subgroup we know as a cyclic group with generator , such that the order of is the same as the order of . In this research, observations were made on the set in order to know the nature of the membership of and the order of for the case of order 2 and further for of order n if G is a cyclic finite group using the effect of Lagrange Theorem.

Abstract

Sanggar Kegiatan Belajar (SKB) Kota Kendari adalah salah satu satuan pendidikan yang melaksanakan Pendidikan formal dan informal di Kota Kendari, Provinsi Sulawesi Tenggara. Universitas Halu Oleo (UHO) sebagai Perguruan Tinggi berlokasi di Kota Kendari memenuhi tanggung jawab melakukan tugas Tri Darma Perguruan Tinggi. Permasalahan yang ditemukan di Pamong Belajar SKB Kota Kendari, yaitu mengalami kesulitan untuk menyelesaikan permasalahan yang diperoleh atau didapat di masyarakat dan kesulitan untuk menentukan metode atau analisis yang cocok untuk menyelesaikan problem yang diperoleh di lapangan. Hasil program ini berupa materi konsep Statistika Dasar dan pengolahan data serta interpretasinya yang mudah dipelajari dan digunakan. Sedangkan tujuan memberikan materi Manajemen Data adalah untuk meningkatkan kualitas layanan pendidikan dan rintisan program baru yang dibutuhkan masyarakat dan diharapkan mampu memenuhi kebutuhan data yang akurat dan mudah diperoleh sejalan dengan Program Pemerintah Provinsi Sulawesi Tenggara tentang Data Sektoral dari berbagai instansi dapat dihimpun menjadi Satu Data. Peserta mempraktekkan di komputer masing-masing dan diberikan contoh langsung bagaimana menyimpan data/berkas di Google Drive. Diajarkan juga cara membuat instrumen identifikasi kebutuhan Belajar Masyarakat melalui Google Form. Pada kegiatan ini, peserta berptaktek langsung didampingi oleh Pemateri dan beberapa mahasiswa Statistika

Abstract

Phishing is a rapidly growing form of cybercrime that poses a significant threat to internet users. Therefore, an effective and accurate detection method is essential. This study aims to analyze and compare the performance of several kernel functions within the Support Vector Machine (SVM) method for detecting phishing websites. The kernel functions used include linear, polynomial, Radial Basis Function (RBF), and sigmoid. The dataset is evaluated using stratified 5-fold cross-validation, with F1-score as the primary performance metric. The results show that the RBF kernel achieves the highest performance, with the best F1-score of 94.64%, followed by the polynomial kernel. The linear kernel performs reasonably well on nearly linearly separable data, while the sigmoid kernel shows the lowest and least stable performance. Based on these findings, the RBF kernel is recommended as the most suitable choice for phishing website detection using the SVM method.
