Abstract

Job vacancies are information that is really needed by many people with a very fast update rate, because it is related to the acceptance deadline. Speed of information and suitability of abilities are basic criteria in the job search process when applying for jobs. However, the distribution of this information is quite difficult to obtain when you have to look for the source of the information in certain places first. For this reason, a solution is needed to simplify these difficulties. The software development methodology used in the system development process is the waterfall methodology. In this methodology, several steps are taken to build software, namely software engineering, system analysis, system design, system implementation, system testing. By carrying out stages based on the methodology, it is hoped that the application will be built according to needs and can be used by consumers. The Job Seeker Application is an application that can help disseminate job vacancy information for job seekers and employers to assist the job application process directly for job seekers.

Abstract

Understanding the electricity tariff class is needed to predict how much usage costs or electricity bills that must be incurred by customers. Each power capacity has a different basic electricity tariff based on the class, household, business and industry. Fuzzy logic can solve problems with imprecise and heuristic data by producing accurate conclusions. The conclusion obtained from the Fuzzy Logic results is expected to be a consideration for customers in predicting electricity usage costs based on electricity tariff groups and customer electrical power capacity. The proposed research uses the Mamdani Fuzzy Logic Method, the use of this method aims to facilitate customers in predicting the cost of electricity usage based on the electricity tariff class and the customer's electric power capacity. The output of this research is the result of predicting the cost of electricity usage based on the power group in residential homes. The higher the tariff group, the number of kWh, electronic goods, and usage time, the higher the predicted energy consumption used. The results obtained from adjusting the fuzzy input antecedents and fuzzy values, namely [900;850;30;20], then for Type_Tariff Power 900, Total_KWh 850, Electronics 30, and Time_Use 20 is 986. Then the cost that must be incurred in the example case above is 1,333,072 rupiah.

Abstract

Conventional physics laboratories often suffer from limitations in terms of equipment availability and safety, which hinders optimal learning of collision dynamics concepts. This research aims to develop a virtual laboratory based on collision algorithm to simulate perfect collision as an alternative solution in physics learning. The development uses the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The collision algorithm was implemented using ActionScript 3, with interpolation allowing for more accurate collision detection at high speeds. The validation results show that the simulation is in line with the law of conservation of momentum and kinetic energy and is consistent with analytical solutions from MATLAB and Python. Functionality testing was conducted by 20 students, and the results showed that the use of this virtual laboratory significantly improved their concept understanding, with the average improvement ranging from 24% to 56%. Students also reported that this virtual laboratory is more interactive and interesting, thus increasing their learning motivation. The conclusion of this study is that the collision algorithm-based virtual laboratory is effective as a physics learning media and can be adopted more widely in technology-based education, especially to understand complex physics concepts more deeply.

Abstract

Applications are software developed to process data and generate information. There are three types of applications, namely desktop applications, web applications, and mobile applications. Mobile applications allow users to access information and resources anytime and anywhere, as long as connected to the internet. Minang nomads are Minangkabau people who live outside West Sumatra, both in Indonesia and abroad. In the city of Manado, Minang nomads often find it difficult to obtain accurate information, such as the number of Family Cards, ethnic or clan groupings, and other important information such as address, occupation, account number, and blood type. With this application, the data of Minang nomads can be centralized and make it easier for them to share information. This application aims to improve relations between fellow Minang nomads in Manado City and strengthen the local economy. Some of the main features of this application include the ease of finding information on the schedule of activities, the number and grouping of tribes, addresses, blood types, as well as the work of Minang nomads.
