A disease that is currently widespread today is caused by the spread of the coronavirus disease or what is commonly called COVID 19. This virus is very dangerous to health because it attacks organs in the human body from various sources, either from the air or direct touch. With the existence of COVID 19, it has an impact on all countries, especially the State of Indonesia, which consists of various islands, which are also affected by the COVID 19 virus. So that the central government takes a policy to carry out social distancing to every one to break the chain of spreading this virus, with this social distancing it has an impact on all activities that occur every day. As an impact on the learning process that usually takes place in class, it turns into online learning that uses several supporting applications in the learning process during the COVID 19 pandemic. With online learning from various applications, it attracts researchers to research with the K-Medoid Clustering Algorithm in using applications during the pandemic COVID 19.

Cervical is the second most common malignant tumor in women, with 341,000 deaths worldwide in 2020, almost 80% of which occur in developing countries. One of the causes is infection with Human papillomavirus (HPV) types 16 and 18. The increasing incidence of cervical cancer in Indonesia makes this disease must be treated seriously because it is one of the main causes of death. In addition to the virus, external factors can be one of the causes. The high mortality rate in patients is caused by the patient's awareness of the emergence of cervical cancer which is only seen when it enters the final stage. One of the efforts to reduce the number of sufferers is to implement cervical cancer detection. Early detection of cervical cancer can also be identified by looking at external factors, such as behavioral factors, intentions, attitudes, norms, perceptions, motivations, social support, and empowerment. However, the data used has an imbalance in the distribution of the target class, namely more negative samples than positive ones. To overcome this, a technique called Stratified K-Fold Cross-Validation (SKCV) is used. Evaluation of the accuracy value using the Confusion matrix to determine the performance of each model. The best performance of the five classification algorithms used is 96 percent (RF), 94 percent (LR), 92 percent (XGBoost), 90 percent (KNN), and 88 percent (NB). The results show that the model formed by RF-based SKCV has the highest accuracy of other models.
Abstrak: Teknologi modern semakin pesat perkembangannya, sebagai masyarakat kita dapat merasakan hal positif dari perkembangan teknologi modern, salah satunya adalah internet. Memanfaatkan internet dengan hal positif dapat mempermudah kegiatan masyarakat, seperti dalam bidang pendidikan salah satunya adalah kegiatan belajar mengajar. Dengan adanya kegiatan belajar mengajar dapat menambah wawasan dan ilmu pengetahuan bagi masyarakat, akan tetapi terkadang pelajar bahkan pengajar yang melaksanakan kegiatan belajar mengajar tersebut terlalu terkekang oleh waktu dan peraturan yang berlaku pada tempat belajarnya. Hasil permasalahan yang penulis dapatkan pada kegiatan belajar mengajar konvensional adalah diharuskannya meluangkan waktu untuk pergi ke tempat belajar dan juga ditentukan durasi belajar mengajarnya bahkan diadakan peraturan yang terkadang membuat peserta sampai pengajar tidak nyaman dengan peraturan tersebut. Oleh karena itu penulis tertarik untuk menyelesaikan permasalahan tersebut dengan membuat sistem informasi pembelajaran (e-learning) dengan metode learner-led learning berbasis web yang dapat diakses dimanapun dan kapanpun tanpa mengeluarkan biaya dan tidak terkekang oleh waktu. Penelitian ini diharapkan dapat membantu dalam proses belajar mengajar dengan nyaman. Website ini juga menyediakan fasilitas seperti materi yang bersifat video dan artikel yang bertujuan bagi pelajar yang lebih nyaman belajar dengan video interaktif dan juga tersedia fasilitas sertifikat sebagai bukti bahwa pelajar telah berhasil dalam menyelesaikan soal dari materi yang dipelajarinya.

Using the internet with positive things can facilitate community activities, such as in the field of education, one of which is teaching and learning activities. With teaching and learning activities, it can add insight and knowledge to the community, but sometimes students and even teachers who carry out teaching and learning activities are too constrained by time and the regulations that apply to the place of study. The results of the problems that the authors get in conventional teaching and learning activities are that they are required to take the time to go to the place of study and also determine the duration of teaching and learning and even make regulations that sometimes make participants until the teacher is not comfortable with these rules. Therefore, the authors are interested in solving these problems by creating a learning information system (e-learning) with a web-based learner-led learning method that can be accessed anywhere and anytime without incurring costs and not being constrained by time. This research is expected to help in the teaching and learning process comfortably. This website also provides facilities such as video materials and articles aimed at making students more comfortable learning with interactive videos and certificate facilities are also available as evidence that students have succeeded in solving problems from the material they have studied.
