One of the activities is to use the internet. The research will conduct a classification based on internet usage data obtained through questionnaires using data mining techniques. The attributes that will be used in doing the classification are Name, Age, Gender, Last Education. The method used is the Naïve Bayes method, which is one of the classification techniques in data mining. Based on the research conducted, it was concluded that based on internet user data used as training data, the Naïve Bayes method succeeded in classifying 32 data from 50 data tested. So the Naïve Bayes method succeeded in predicting the magnitude of the percentage of accuracy by 64%. Keywords : Data Mining, Classification, Naïve Bayes

With the many types of car choices offered, it is not uncommon for many customers to feel confused in choosing what type of car suits their needs. This problem is often experienced by customers who are confused by the many choices of car types available. In this study, the k-means algorithm was used to group cars based on several attributes. The k-means algorithm can be used to group car type data to help provide recommendations for choosing a car type. The purpose of this study is to make it easier for customers to choose the type of car that is most in demand and as material for PT. Station Armada Indonesia to respond better to market changes and achieve better results. Grouping car rental fleets based on rental prices and mileage by utilizing the k-means algorithm can help PT.

From the grouping results, two cluster groups were obtained with the character of the first cluster being less in demand by customers and the second cluster group being the most in demand by customers. So that the company can easily prepare the type of fleet that is most in demand. In the application of data mining methods using k-means is very helpful and makes it easier for PT. Station Armada Indonesia to develop more effective marketing and offering strategies. By grouping car types with the implementation of k-means can facilitate customer knowledge in choosing car types based on customer needs.

Abstract

SD PAB 23 Patumbak telah memiliki infrastruktur WiFi sekolah, namun pemanfaatannya belum optimal untuk mendukung pembelajaran digital karena keterbatasan literasi digital guru. Sebagian besar guru masih menggunakan akses internet hanya untuk kebutuhan administratif, sehingga potensi WiFi sebagai sarana pembelajaran interaktif belum dimaksimalkan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengoptimalkan pemanfaatan WiFi sekolah guna meningkatkan literasi digital guru di SD PAB 23 Patumbak. Metode pelaksanaan meliputi observasi awal kondisi pemanfaatan WiFi, pelatihan berbasis praktik tentang konsep dasar jaringan komputer dan penggunaan WiFi untuk pembelajaran, pendampingan pemanfaatan sumber belajar digital, serta evaluasi melalui pre-test dan post-test. Kegiatan diikuti oleh 10 orang guru dan dilaksanakan secara partisipatif. Hasil evaluasi menunjukkan adanya peningkatan signifikan pada kompetensi guru, dengan rata-rata peningkatan pengetahuan dan keterampilan sebesar 55,3%. Peningkatan tertinggi terjadi pada aspek keterampilan kolaborasi daring (68%) dan pemanfaatan sumber belajar digital (60%). Kegiatan ini berdampak positif terhadap kesiapan guru dalam mengintegrasikan teknologi jaringan ke dalam proses pembelajaran serta memperkuat literasi digital di lingkungan sekolah. Dengan demikian, optimalisasi WiFi sekolah melalui pendampingan terarah terbukti efektif dalam mendukung transformasi pembelajaran digital di sekolah dasar.
