Since August 14, 2020, the government has provided social assistance, namely Direct Cash Assistance for MSMEs, as much as 1.2 million for MSME actors. The submission process is done online through the Google Form, which is managed by the Malang City Cooperative, Industry and Trade Office. However, during the submission process, there were problems such as a lack of information on the Google Form, no follow-up announcement on whether the submission was accepted or not, and some applicants could not access the submission link. So from these various problems, researchers will design a User experience in the Application for Registration of MSMEs in Malang City Cash Direct Assistance. During the Pandemic Period. The method in this study uses the Human-Centered Design (HCD) approach. This method focuses on humans and users who can assist researchers in designing solutions according to user needs and system usability to increase productivity, efficiency, and effectiveness so that people get their satisfaction. In the final stage, the researcher conducted usability testing for five respondents. The result was 100% on the effectiveness aspect, 0.085 goals/second on the efficiency aspect, and 82.5 with the excellent category and scaled A on the user satisfaction aspect. Based on the test results, it can be concluded that the design of the solution that has been designed is acceptable.

The use of VR in the tourism business continues to increase. The use of VR for tourism is known as virtual tourism. virtual tourism can simulate tourist destinations using a virtual environment (VE). Virtual tourism is expected to enhance the experience for tourists and attract new markets to tourist destinations. Malang City is one of the tourist destinations in East Java, and is always visited by both domestic and foreign tourists. However, Malang City is still not a major destination in tourism, compared to Batu City (Kota Batu) and Malang Regency (Kabupaten Malang), this is due to the lack of vigorous promotion. In order to provide a pleasant experience for its users, Malang Virtual Tourism must be developed based on user needs. Based on these problems, a virtual reality application will be developed that can provide immersive experiences to users related to tourist destinations in Malang City. At the requirement analysis stage, a specification design of the system to be made includes functional and non-functional requirements needed for the development of the system in this research will be carried out. The requirement analysis process involves potential users of the system. We were identifying the requirements by numbering each requirement that has been made with a Use case diagram and Use case Scenario. This step generates a general description and system requirements. The results of this stage get five functional requirements and one non-functional, usability.

Diabetes is a chronic disease that occurs when the pancreas can’t produce enough insulin or when the insulin hormone can’t be used effectively by the body. The condition of the increased blood sugar, known as hyperglycemia, is a short-term impact that often occurs in uncontrolled diabetes. Meanwhile, the long-term impact of uncontrolled diabetes can cause damage to various body systems, especially blood vessels and nerves. Early detection of diabetes in individuals who are susceptible to diabetes is the main key to control diabetes issues. Artificial intelligence can help this issue. Early diabetes detection with artificial intelligence can predict whether a person in the next 5 years has the potential to suffer from diabetes type 2 or not, based on six variables including 2-hour plasma glucose concentration in the oral glucose tolerance test, diastolic blood pressure, fold thickness triceps, body mass index, diabetes pedigree function, and age. The prediction was built by using similarity classifier based on p-probabilistic extension, trained with the Pima Indian Diabetes dataset with women as research subjects. The contribution of this research is to select representative features in the Pima Indian diabetes dataset then implement them with similarity classifier based on P-Probabilistic Extension. The aim of this study is to compare similarity classifier algorithm with K-nearest neighbor as classifier that widely used in Pima Indian diabetes dataset. The test scenario is carried out by dividing 70% of the training data and 30% of the testing data, then the accuracy for the Pima Indian diabetes data will be compared with K-nearest neighbor and the similarity classifier. Accuracy shows a success value of 75.38%, so the similarity classifier that is built can be used to predict potential diabetes with better performance than K-nearest neighbor.

Abstract. Optimal healthy diet in accordance with the allocation of cost needed so that the level of nutritional adequacy of the family is maintained. The problem of optimal healthy diet (based on family budget) can be solved with genetic algorithm. The algorithm particle swarm optimization (PSO) has the same effectiveness with genetic algorithm but PSO is superior in terms of efficiency, PSO algorithm has a lower complexity than genetic algorithm. However, genetic algorithms and PSO have a problem of local optimum because these algorithm associated with random numbers. To overcome this problem, PSO algorithm will be improved by combining it with simulated annealing algorithm (SA). Simulated annealing algorithm is a numerical optimization algorithms that can avoid local optimal. From our results, optimal parameter for PSO-SA are popsize 280, crossover rate 0.6, mutation rate 0.4, first temperature 1, last temperature 0.2, alpha 0.9, and generation size 100.Keywords: PSO, SA, optimization, variation, healthy diet menu.

Indonesian people should actively preserve Indonesian culture. A way to preserve Indonesian culture can be done by using Javanese scripts as a local content subject at elementary to middle school level. In the conventional learning method, almost all teachers teach writing Javanese manuscript with conventional instructional media by using a white board. We proposed a mobile application that can help students to learn how to write Javanese script in attractive way by using their finger. Since this application still in prototype stage, further study and analysis of the usability of this application are necessary to validate the feasibility in real implementation. Usability testing using USE questionnaire had been conducted to find out if application of Javanese script writing can be accepted by users. We give 30 questions about usability to 5 respondents that are familiar with android application. The result show that, the proposed application is acceptable to users in term of Usefulness, ease of use, ease of learning and satisfaction.

Recipes are used as a reference in processing cooking ingredients to meet personal nutritional needs, considering the ingredients used to make food sold freely that is not necessarily guaranteed in nutritional quality and safe to consume, especially during the pandemic as it is today. So cooking itself becomes a better alternative for the community. With a large number of food recipe options available for various media, the role of a Decision Support System is needed by people who will get food recipe recommendations. Research related to recipe recommendations that have been done are using SAW only and some add experts as a source of knowledge to provide value on the variable time and complexity of cooking recipes. Therefore, in this study, a comparison between the research of recipe recommendations with SAW only and research that added a subsystem of knowledge management derived from experts to support the decision support system of food recipe recommendations was conducted by using correlation testing. The results is there is a strong correlation between knowledge based SAW and user preference to the value of 0.9774. The result is better than SAW only and user preference with the value of 0.7262.
