Diabetes was a disease that occurs due to high blood-glucose levels. Researchers tried to prevent complications from developing by using data mining techniques. One of the techniques used in data mining was classification. The purpose of this study improves the accuracy of the classification of diabetes for a better and optimal result. The method in this study is Correlation Feature Selection (CFS) as attribute selection, Random Over Sampling to handle unbalanced data and AdaBoost to improve the performance of the J48 algorithm so the result obtained best. Based on the result of this study, showed that Correlation Feature Selection for attribute selection and Random Over Sampling to handle imbalance's class with the Adaboost-based J48 algorithm proved can increase the results of the diabetes classification with an accuracy of 92.3%. For the further research recommended to apply other methods so that the accuracy results obtained are more optimal for comparison.

Information technology is one thing that has an important role in the current era, especially during the pandemic. Complaints or submission of aspirations and student complaints are important in an institution or college, because with the delivery of these aspirations a university can easily improve and improve its quality. Building student confidence in the services and facilities and infrastructure carried out by the organizers is an activity that must be carried out with the expectations and demands of students regarding service improvement. This student complaint system is a website-based system that is useful for assisting Tegal Steel Polytechnic students in submitting complaints to universities. Services regarding receiving complaints and responding to complaints are still manual. Students must come to the secretariat to fill out the form directly. Therefore, with the development of technology, it encourages authors to create a website-based information system that can help students who want to make complaints. Therefore, researchers build a website-based system that makes it easier for students to make complaints and see how far their complaints have been processed by the university.

Virus corona yaitu virus yang menyebabkan infeksi saluran pernapasan pada manusia. Jumlah kenaikan penderita virus corona meningkat secara cepat dan menyebar diberbagai negara. Dalam menghadapi virus corona dunia pendidikan mengantisipasi agar penularan virus corona tidak semakin luas yaitu dengan menghentikan proses pembelajaran secara langsung dan digantikan dengan pembelajaran daring. Dalam proses pembelajaran daring tidak selalu berjalan secara baik ataupun lancar, banyak kendala yang dihadapi selama pembelajaran daring. Kendala yang ada selama proses pembelajaran daring berakibat terhadap perubahan peserta didik seperti menurunnya motivasi serta prestasi belajar mahasiswa. Berdasarkan alasan tersebut peneliti tertarik untuk menganalisis hasil prestasi mahasiswa selama pembelajaran secara daring dengan menggunakan teknik data mining yaitu teknik klasifikasi. Salah satu teknik data mining untuk melakukan klasifikasi yang dapat digunakan adalah algoritma J48. Algoritma J48 merupakan algoritma yang cukup populer dalam pengklasifikasian, namun memiliki kelemahan yaitu dalam proses klasifikasi tidak dapat memilih atribut yang relevan, hal ini dapat berdampak buruk saat proses membangun decision tree. Untuk mengatasi masalah tersebut peneliti menerapkan Correlation Feature Selection untuk seleksi atribut dan Adaboost dalam memperbaiki performa algoritma J48. Hal ini dibuktikan bahwa setelah penerapan metode yang digunakan hasil akurasi yang di peroleh menunjukan peningkatan yaitu sebesar 96,42 %.

The rapid development of information systems in the current era of globalization has made almost all aspects of life unavoidable from the use of computer devices, especially in educational institutions. The number of SMA/equivalent in Indonesia is 15,497, namely in public schools there are 7,203 (46.48%) and private schools 8,294 (53.52%). West Java Province has the highest number of schools, namely 1,823 schools. Meanwhile, Indramayu Regency has 89 SMA/equivalent with details of 26 state and 63 private. One of them is SMA NU Tenajar Kidul. The school has problems with the presence of students. Often students do not enter school without explanation. However, after follow-up was carried out by the school, they received information from the parents of the students that their children were leaving home from home. So that these students are truant and cause not get knowledge in school. The need for a touch of technology that can bridge the school with parents of students. So that when there is a problem that one of the students is absent, the school can provide information to parents quickly and accurately. Therefore WhatsApp API is the right choice to provide attendance information to parents. The system was built using the nodeJS programming language and got the test results of 40 messages, getting the message sending process time of 0 milliseconds. While the time needed by the API to process the message sending is the longest 0.10522 milliseconds. If you calculate the average length of the message sending process, it is equal to 0.037826 milliseconds. Thus the WhatsApp API that has been built is very effective with performance under 1 second. All messages stored in the table are 100% sent.

Letter is a means of communication to convey written information by one party to another and also serves as a reminder. In an educational institution, letters are very important, both outgoing and incoming letters that have different subjects. Therefore, in recording incoming and outgoing mail documents, it is necessary to archive documents as a form of good mail administration management. Archives are recorded information in any form of media, which are created, received and managed by an agency or individual in the context of carrying out activities or because of their legal obligations which have an important role as a source of information. One of the schools in the Indramayu area, especially SMA Negeri 1 Sliyeg, in managing letter archives still uses manuals recorded in ledgers and letter administration documents are stored in binders, so that it becomes less efficient in managing letter archive document administration. So that a computerized administration filing application for incoming and outgoing mail is made. In making applications for archiving incoming and outgoing letters, you can use the PHP programming language, data storage with a MySQL database, display applications with the Codeigniter Framework, and notebook or computer hardware. This application can save correspondence files with image file formats. Can make it easier to search for mail archives in the form of reports based on date, month, and year.

In the use of information systems and technology, risk is something that must be anticipated. Risks can arise from various things such as information security, fire, hardware damage, etc. that can disrupt the organization's business processes. With the possible emergence of risks in the use of information systems and technology, risk management is needed to facilitate the identification of possible occurrences of these risks. Risk management is the practice of identifying, assessing, controlling and mitigating risks. SMK Negeri 2 Baleendah is a vocational high school that has 5 areas of expertise competence, namely culinary, beauty, fashion, industrial chemistry, and computer network engineering. SMK Negeri 2 Baleendah as an organization engaged in education has implemented online exam information technology. Of course, the application of information technology raises a problem. From these problems, risk management is needed to minimize risk by conducting a risk assessment. NIST 800-30 is a standard document developed by the National Institute of Standards and Technology. NIST 800-30 has two important stages, namely risk assessment and risk mitigation. This research will use the NIST SP 800-30 method as a method that will solve the existing problems. Therefore, a risk assessment was chosen using the NIST SP 800-30 method (Case Study: SMK Negeri 2 Baleendah)
