2022-12-28T08:12:10+00:00

Culinary is a type of business that will always exist, this is because one of the factors of human needs is in the form of food. Therefore it is necessary to have a system that provides recommendations to provide input to consumers to minimize consumer confusion about the many culinary places. In this study, to obtain recommendations, the Item-based Collaborative Filtering method will be used to approach consumers with one another. Meanwhile, to get this approach, the approach that will be assessed is an approach to rating culinary places, to get a consumer rating it will give value to 4 aspects, namely: place value, service value, view value, and speed of service value. This study uses the consine similarity algorithm to get the value of the approach. The results obtained by this study using the Likert scale method got a value of 71.6656% "fulfilled". Meanwhile, in the black-box test, the score is 100% functioning, and in the test to determine the accuracy of manual calculations and the system, the value is 100% the same.

Asynchronous e-learning web prototyping for first-grade students learning (case study: SD Muhammadiyah Inovatif Pujotomo Magelang)

2022-12-28T08:12:10+00:00

Distance learning (online) is currently a learning tool that plays an important role during this pandemic, one of which is affected, namely in the field of education at Muhammadiyah Innovative Elementary School Pujotomo Magelang. The difficulty experienced by teachers and students is in the online learning system which uses a lot of media platforms such as Quizziz, Google Classroom, Youtube etc. so that material data, assignments and grades for each subject will be easily mixed and lost. This makes it difficult for students to find material data and past assignments, while teachers find it difficult to find data on assignments that have been collected and quiz scores that have been done by students because there is no copy of the data. E-learning is a learning media that really helps teachers and students in carrying out the teaching and learning process. The asynchronous e-learning method is a means for teachers and students to interact such as giving materials, assignments, quizzes, attendance and giving grades so that teachers and students can easily find data according to their subjects. The results of the asynchronous e-learning test using blackbox testing went well, did not experience any errors. Subsequent testing using UAT with several users, namely admin with 97%, teachers 91%, and grade 1 students 93% it can be concluded that the user's needs have been met.

E-learning user interface design for lecturers based on usability scale system approach (Case Study: E-Learning Universitas Muhammadiyah Magelang)

2022-12-28T08:12:10+00:00

Universitas Muhammadiyah Magelang provides an online learning service portal through an e-learning website MOCA. However, the low level of use of the MOCA website and the usability problems that usually arise in MOCA, indicate the need for usability testing. Usability testing is carried out to measure usability aspects, namely: effectiveness, efficiency, and user satisfaction. This study used a System Usability Scale questionnaire which was tested on 61 lecturers. This study aims to measure usability aspects according to the user's subjective assessment. The results of the study can describe the level of usability of MOCA from the user's point of view. the results of the MOCA usability test using the SUS method got a score of "64" and this figure is still below the average (below average) of 68. For acceptable ranges, it shows that the current MOCA is in a "marginal (high)" position, for the grade scale gets a “D” predicate, and for adjective ratings it can be said to be “OK” and that means the current MOCA quality score is acceptable but needs a lot of improvement. In addition, this study provides recommendations in the form of a prototype designed based on suggestions from respondents and then tested based on the heuristic aspects of the relevant journal. The prototype design that has been designed is tested on 5 respondents as evaluators. The results of the heuristic test obtained were "4.32" which means 5 respondents were "satisfied" with the prototype user interface design proposed by the researcher.

Implementation of rapid application development methods and reminder systems in the development of inventory information systems (case study: sansaquaman aquascape store)

2022-12-28T08:12:10+00:00

Aquascape is a new thing that is very popular in this pandemic era, the number of people who are interested in making this aquascape creates a fairly large business opportunity during this pandemic. The business of selling aquascape accessories has quite a big opportunity because of the many enthusiasts in making aquascapes. Sansaquaman is one of the shops engaged in the sale of aquascape accessories. The large number of buyers of goods in this store has resulted in several problems, such as employee errors in entering goods, calculating the stock of goods and also in ordering to suppliers. Therefore, there is a need for a system to overcome some of the problems that exist in the Sansaquaman store in order to minimize human errors, errors in calculating inventory stock and ordering goods to suppliers. In this study using the Rapid Application Development (RAD) method, so that in making the system it can be in accordance with user requests and in a short time. In this study also used 2 tests, namely the User Aceptance Test (UAT) and blackbox with the results of the User Aceptance Test from 3 users, namely 95% employees, 93% suppliers and 92% operators, while the black-box test got a value of 100%.

Grouping community reading interests using the k-means clustering method (case study: Magelang district library and archive service)

2022-12-28T08:12:11+00:00

So far, the problem of gathering information at the Library and Archives Office of Magelang Regency is relatively low. To increase reading interest, policies are needed to determine reading interest. So the data used is book transaction data. This study aimed to classify people's reading interests according to the number of borrowed books at the Magelang Regency Library and Archives Service using the K-Means Clustering method and to find out which book categories are most in demand by the public at the Magelang Regency Library and Archives Service. One way to manage this data is to use data mining using the K-Means method. The results of this study are low reading interest, evidenced by using 2 clusters and the category of books that are most in-demand Literature with a high cluster strength value, namely with a Silhouette Coefficient value of 0.7354.

Implementation of the prototyping method in the development of information systems (case study: pelangi laundry)

2022-12-28T08:12:11+00:00

Laundry Pelangi is an individual company engaged in laundry services. Laundry Pelangi is located in Rejosari RT 01 RW 09 Mungkid, Magelang Regency. Currently, Laundry Pelangi's transaction notes and income reports are still done manually using paper-based notes. The manual process has many shortcomings, including inaccurate recording or missing records. This research will develop a laundry information system to help make it easier for employees to manage data and function to create a service feature in the form of free laundry. The method used in the development of this system is the prototyping method, namely identifying user needs, making prototypes, testing prototypes, improving prototypes, developing production versions. Through the development of this system, the transaction ordering process and income report data can be stored properly. The results of the overall test conducted by consumers, employees, and owners obtained a value of 92.11%, which means it is very feasible. It is concluded that the system built can make it easier for employees to process input transactions, print notes and print consumer cards, while consumers make it easier to order laundry and monitor laundry status.
