Cases of biological food poisoning can be caused by several causative factors, one of which is a food processing site that does not meet health requirements. According to the BPOM report (2016) cases of food poisoning in Indonesia in 2016 reached 1,068 cases. In 2016, 60 extraordinary events (KLB) of food poisoning were reported by 31 BB/BPOM throughout Indonesia. From the many cases of food poisoning that occur, it is necessary to take action in prevention by processing data on existing cases of poisoning to follow up on existing problems to reduce the number of cases of food poisoning by using a system on a computer so that the managed data can be processed quickly to obtain further information. Therefore the author wants to use a system with the clustering method to assist in processing data on biological poisoning cases grouping objects based on the characteristics of each object. Based on the research conducted, it can be seen that in cluster 2 in the dasta group of biological poisoning cases there are 11 data with centroid point age (x) 2, namely 12-16 years, centroid point on the type of poisoning (y) 6.36, namely sandwiches, and centroid point on the causative factor (z) 2.9, namely Gram-negative rod-shaped bacteria which are usually found in the intestines of humans and warm-blooded animals.

Respiratory tract disease is a common condition that can affect anyone regardless of age. Starting from relatively mild symptoms to alarming symptoms. Although some respiratory diseases are not life-threatening, they should not be taken lightly as they can cause serious complications. What often happens is that it is difficult for a patient to see a specialist doctor because of the limited number of respiratory specialists who cannot fully serve patients, so people often have difficulty if they want to consult directly. This triggers the habit of the community to treat complaints on their own with simple drugs bought freely at drugstores or pharmacies without knowing for sure the disease they suffer, as well as the length of waiting for queues, consultation fees that are quite expensive and not everyone has a short distance to the hospital prefer not to go to a specialist. Like other organs of the human body, breathing is also prone to various diseases. Respiratory organs will be disrupted and can even cause death. By using the Naïve Bayes method above, it is known that the diagnosis of respiratory disease is that the young female patient is diagnosed with a type of respiratory disease called Farangitis (P05) with a percentage of 47.44%.

Online learning is widely used by various groups, especially in higher education/schools. Online learning has many benefits for students and lecturers due to its practical and flexible learning process. However, there are complaints in online learning, such as students having difficulty understanding the material shared by lecturers and the lack of interaction between lecturers and students, making the lessons monotonous and boring. Students also cannot review the targeted lecturers. Therefore, the Midori Clon application was created to address students' problems in online learning. The application design was developed using the Design Thinking method. The Midori Clon application offers several advantages, including a Live Video feature for more interactive sessions between students and lecturers, a Bot feature to summarize materials and translate languages, and a Lecturer Review feature to review the targeted lecturers. With these advanced features, it is expected that online learning issues can be resolved and online learning can meet the desired expectations.
 
 

Advances in information technology have become a major influence on society in meeting needs, quality and convenience. One example of technological progress is online sales. E-commerce or online shops can make it easier for people to shop with time efficiency, accuracy and quality and can make it easier for the shop to sell because it can promote the products it sells more widely and get maximum profits. This research focuses on designing the UI/UX for cosmetic sales at beauty cosmetic stores. Researchers found problems in beauty cosmetic stores in that store management was still manual, only using social media as promotion without an online sales platform so that the income obtained from sales was not optimal. The method used in designing the UI/UX for selling cosmetics at this beauty cosmetic shop is using the prototype method. The results of this research are the UI/UX design for selling cosmetics at beauty cosmetic shops which can make it easier for beauty cosmetic shops to market their products. It is hoped that this learning media can increase people's interest in shopping at beauty cosmetic stores.

Tuberculosis (TB) is one of the infectious diseases caused by Mycobacterium tuberculosis bacteria infection in the human lungs. Tuberculosis is a disease that can be transmitted from people with TB through coughing, sneezing, talking, laughing or singing. Lack of public knowledge about TB and lack of funds for health checks make many people late to be treated. Expert systems are technologies developed based on programs, in accordance with human methods and mindsets. This aims to help people who want to check their health, but are hampered by costs, besides saving time if the examination place is far from the residential environment of the community concerned. Expert systems require a method that can help solve existing problems. In this study, the method used is the Case-Based Reasoning (CBR) method, because the main function of this method is to diagnose the disease. The calculation process of the Case-Based Reasoning (CBR) method which looks for the similarity value or proximity of old cases to new cases of a patient.

Fine motor skills are movements carried out by the fingers with a central nervous cell arrangement that regulates the use of small muscle groups such as the fingers and hands, and often require precision and coordination with the hands. One type of game that can optimize children's fine motor development is puzzle games. Puzzles are a type of game that improves thinking skills, makes it easier to remember and understand concepts, and increases creativity.
