The importance of health for everyone to be able to empower everything that is owned and the environment maximally, health is closely related to healthy living. So that can be described the meaning of healthy life is to have health in life with no problems of disruption in life both physical in the form of disease in the body and non-physical that is related to the condition of the soul, heart and mind of a person in life both individually and socially. The use of expert systems with the search model with the Fuzzy Mamdani method can help to know the condition of the disease that may be suffered by each individual based on the pattern of life that he did.

Expert System for Disease Risk Based on Lifestyle with Fuzzy Mamdani

Data Mining is a process of exploring against large data to find patterns in decision making. One of the techniques in decision-making is classification. Classification is a technique in data mining by applying decision tree method to form data, algorithm C4.5 is algorithm that can be used to classify data in tree form. The system has been built that shows the results of good performance and minimal error in view of the system that is able to distinguish the anomaly traffic with normal traffic. Data mining inventory system applications can facilitate the control of inventory in the company to reduce production costs.

C4.5 Classification Data Mining for Inventory Control

Cryptography is a field of science that can be learned to secure data and information, cryptography is used in almost all communications both in network and non-network; and one of the algorithms could use is RC4 algorithm, publication about RC4 algorithm is quite a lot but the discussion is dominant only theory alone does not complete the RC4 algorithm process in detail and applications only show input and output none of the processes include, in this research paper illustrates the process of RC4 algorithm in detail and with visualization to demonstrates the work of RC4 algorithm to make it easiest for readers to learn cryptography

Decision Support System is an interactive system that supports decision in the decision-making process through alternatives derived from the processing of data, information and design of the models. Selection decision support system of chemical fertilizer in fruit plant is expected to help anyone who wants to cultivate fruit trees can determine the chemical fertilizer as expected based alternatives and criteria set by the user. In this research method used is TOPSIS Method and Method of Fuzzy Logic. TOPSIS method is one of multiple criteria decision making method that uses the principle that the alternatives selected must have the shortest distance. Fuzzy Logic is a methodology of control systems troubleshooting, the fuzzy logic stated that everything is a binary which means it is only two possibilities, \"Yes or No\", \"True or False\", \"Good or Bad\", and others. Therefore, all of these can have a membership value of 0 or 1.

Comparison Analysis of TOPSIS and Fuzzy Logic Methods On Fertilizer Selection

Searching is a common process performed by many computer users, Raita algorithm is one algorithm that can be used to match and find information in accordance with the patterns entered. Raita algorithm applied to the file search application using java programming language and the results obtained from the testing process of the file search quickly and with accurate results and support many data types.

Searching Process with Raita Algorithm and its Application

In this research modeled a search process of the Knuth-Morris-Pratt algorithm in the form of easy-to-understand visualization, Knuth-Morris-Pratt algorithm selection because this algorithm is easy to learn and easy to implement into many programming languages.

The search process is used in various activities performed both online and offline, many algorithms that can be used to perform the search process one of which is a hash search algorithm, search process with hash search algorithm used in this study using double hashing technique where the data will be formed into the table with same length and then search, the results of this study indicate that the search process with double hashing technique allows faster searching than the usual search techniques, this research allows to search the solution by dividing the value into the main table and overflow table so that the search process is expected faster than the data stacked in the form of one table and collision data could avoided.

Pandemi Covid-19 mengakibatkan sekolah-sekolah melaksanakan pembelajaran daring. Seluruh elemen pembelajaran dilaksanakan secara daring baik penyampaian materi ajar, tugas, maupun ujian. Sekolah-sekolah saat ini banyak mempersiapkan Learning Management System (LMS) salah satunya adalah ujian online. Ujian online ini dibutuhkan agar pelaksanaannya dapat di lakukan secara daring di rumah siswa. Ujian online ini dapat menyelesaikan permasalahan orang tua dan siswa di dalam upaya menerapkan protokol kesehatan yaitu menghindari kerumunan. Ujian online yang dilakukan juga mengadopsi Metode Multi Random Number Generator yang diharapkan dapat melakukan pengacakan soal sehingga siswa yang ujian pada waktu bersamaan tidak dapat bekerjasama dikarena soal yang muncul berbeda satu dengan yang lain pada waktu yang sama. Hasil dari pengabdian masyarakat ini adalah sebuah manajemen sistem pembelajaran yang mampu mengatasi masalah sekolah, orang tua, dan siswa dalam proses ujian harian, ujian mingguan, ujian tengah semester dan ujian semester. Diharapkan manajemen sistem pembelajaran yang dibangun menjadi solusi bagi sekolah-sekolah yang menerapkan pembelajaran secara daring. Kata kunci : Covid-19, Sekolah Daring, Web Based Test, Ujian Online, LMS
