At this time the learning process is still partially carried out online (in the network) considering the positive cases of Covid-19 that still exist in the Semarang City area. The implementation of online learning is not without problems, even in several countries, especially Indonesia, it is reported that countries that adopt online learning on average are actually much smaller than expected. The implementation of online learning makes students less understanding of the learning materials provided and students' low interest in learning during the pandemic. This study aims to create a learning application for grade VI elementary school students that contains learning materials, practice questions that are randomized using LCM and facilitate the results of the assessment of the questions. From the results of LCM randomization, each student did not get the same or twin questions. From the test of 3 students, it was found that the questions that appeared in the same order were question number 6, while the questions that appeared in a different order were questions number 2, 3, 4, 5, 7, 8, 9, 10

Special-based backends are one of the media for selling by-products on the catapult. The purpose of this research is to construct typical web-based appendage by-by-products. The purpose of this research is to construct typical web-based appendage by-by-products. Research methods used in the construction of systems on this research are the methods of research and development (R & D). This study provides several design systems, the design of system architecture, the DFD system, the design of the interface, and the design of system testing. The system was created using the framework laravel. As for the results of the final assignment research "typical web-based appendage". In this system, there are two users, the user as the store and the user as the buyer. On the user as a store there are several features that include input from store products, editing from products, confirmation of deliveries, responding to comments given by the buyer on the product, viewing the order data done by the buyer, and editing the store's data. While the user's features as the purchaser look at the product's data, see the store's data as a souvenir, order a by-product payment, confirm the order has been accepted, give an assessment of the product's already received, and edit the customer's data. The system was tested by using black box methods testing to see the effectiveness of a system built with test variables was 100%.

The search is often used to search for the shortest route, the Hill Climbing Method is a part of the test that uses heuristic functions. The problem that is often encountered is in the form of miscalculations in calculating the distance so that it requires long distances, costs a lot and takes a very long time. To solve this case, it can be solved by making a structure graph by looking at the city points from the two sides of the point to be passed. Using an algorithm can help make it easier to find a location and save time and travel costs that will be passed. This advantage is that all points will be obtained and checked from the right and left sides one by one so as to obtain effective and maximum results. The Hill Climbing method that will be used has the concept of a geographic information system as a guide and is used as a system for decision making. The heuristic search method is one of the methods commonly used in finding a way

Management of medical actions carried out in handling patients who are ODP (people under monitoring), OTG (asymptomatic people), PDP (patient under monitoring) and positive Covid-19 patients is carried out based on assumptions, such as self-isolation, hospitalization, or special treatments in the ICU (Intensive Care Unit) room. The condition of the body in each patient is different, a patient may have same symptoms but the treatment is different, especially in elderly patients. Many problems occur in determining medical action because the patient's body condition is different. Therefore, it needs to be appointed as a research. The research method used in this study was Nive Bayes algorithm with supporting application Rapid Miner. It was applied to carry out the process of testing on patient data as much as 500 data, 25 variables or patient symptoms and 3 outputs as a form of medical action. Based on the results of the analysis carried out in this study, prediction of medical actions for ODP, PDP, OTG and positive Covid-19 patients were obtained by comparing training data with testing data using Rapid Miner application. It resulted that an accuracy rate of 76.00% was obtained

Security issues of a system are factors that need to be considered in the operation of information systems, which are intended to prevent threats to the system and detect and correct any damage to the system. Distributed Denial of Services (DDOS) is a form of attack carried out by someone, individuals or groups to damage data that can be attacked through a server or malware in the form of packages that damage the network system used. Security is a mandatory thing in a network to avoid damage to the data system or loss of data from bad people or heckers. Packages sent in the form of malware that attacks, causing bandwidth hit continuously. Network security is a factor that must be maintained and considered in an information system. Ddos forms are Ping of Death, flooding, Remote controled attack, UDP flood, and Smurf Attack. The goal is to use DDOS to protect or prevent system threats and improve damaged systems. Computer network security is very important in maintaining the security of data in the form of small data or large data used by the user.

Rice is the most important staple food for humans to have energy to carry out activities. The purpose of this study is to provide information to the public in the form of a reference for selecting rice based on consumer interest, so that it can be used as a decision making in buying rice. The Mamdani method is a method that is able to solve problems in the case of rice selection based on consumer references. The work process of the Sugeno method consists of four parts, namely fuzification, inference engine, implication function amplification and the last one is defuzzification. The final result, the Mamdani method has the characteristics of using the AND operator and using the min-max value. This research is in the form of a decision-making system in rice selection based on references from consumers by looking at four aspects of criteria such as price, quality, taste, and shape variables, these four aspects can be used as a reference in rice selection. Sugeno fuzzy logic to get the final value.The Mamdani method is a very effective method in selecting rice according to the needs and interests of consumers so that potential consumers can easily choose rice according to their interests and desired criteria.
