The use of electric vehicles is now supported by a braking system capable of absorbing energy wasted from the braking process, known as regenerative brake. This research aims to optimize the use of the regenerative brake system by adding an alternator as a power generator to achieve more optimal charging. The voltage magnitude in the testing of the electric motorcycle NIU GOVA 03 obtained a generation voltage of 26VDC when traveling downhill for 100 meters at a speed of 45km/h. After designing the alternator for the electric motorcycle, the generation output increased to meet the battery charging voltage specification of 74VDC, suitable for application as a power source for a battery with a capacity of 60V14.7Ah. The braking portion before using the regenerative brake system over a distance of 100 meters took 4.8 seconds, but after implementing the regenerative brake system, the time decreased to 5.1 seconds. This indicates that the regenerative brake system, coupled with the alternator, can provide an effect in the form of decelerating the electric motorcycle by 8.7%.

A common problem that occurs in a company is how to predict future production by utilizing historical data that has been previously recorded, to minimize errors in providing a stock of goods and increasing production efficiency so as not to waste more costs. This research aims to identify and analyze the results of production forecasting using the moving average and exponential smoothing methods in the forecasting calculation process to determine the future stock of goods. Data processing using rapidminer programming, from the prediction results using both methods states that the exponential smoothing method with an alpha value of 0.9 is superior to the moving average method with a request result of 23661.5 MAD = 70.7 and MSE = 12387.9987 smaller than other methods.

Taekwondo Indonesia Integrated System is an application designed to manage various administrative and operational aspects related to the Taekwondo organization in Indonesia. Taekwondo Indonesia integrated system aims to improve coordination and communication between administrators, coaches, athletes, and members, as well as to ensure a more integrated and transparent administrative process at all levels of the organization. This research aims to evaluate the successful implementation of the Taekwondo Indonesia Integrated System using the HOT-Fit methodology. This research explores how various human, technological, and organizational aspects affect the success of the system. Data were collected through questionnaires measuring the dimensions of system quality, information quality, service quality, user satisfaction, system usage, organizational structure and net benefits, which were then analyzed using SPSS and PLS-SEM software. The results showed that service quality has a positive influence on user satisfaction, while system quality and information quality do not significantly affect user satisfaction or system usage. In addition, user satisfaction has a significant effect on system usage and net benefits, with organizational structure also playing a positive role in increasing net benefits. Improved service quality and a strong organizational structure are key to maximizing the success and benefits of the Taekwondo Indonesia Integrated System application. This research provides a practical contribution to the development and implementation of information systems in sports organizations, especially Taekwondo. In addition, the results of this study can be used as a basis for future improvements and enhancements to the TIIS application, so as to increase the efficiency and effectiveness of the operations of Taekwondo organizations in Indonesia.

Pertamina has issued a cashless application for fuel purchases since July 2019, named as MyPertamina. The application aims to make it easier for customers to make payments in transactions at fuel stations. MyPertamina application can currently be downloaded on Google Playstore. Since its release until now, MyPertamina has been downloaded as many as 10 million with a rating of 3.1 and 339 thousand reviews. Unfortunately the low rating and user reviews dominated by negative comments show that the app's performance is still not satisfactory. The reviews data can be converted into valuable information by using entiment analysis. Many researchers have applied sentiment analysis to MyPertamina user comment data. However, there have been no studies that apply the handling of negation in MyPertamina reviews, even though negative comments are very often found the word negation, i.e ‘tidak’,’jangan’,’belum’ and ‘bukan’ that will change the sentiment of next sentiment word. Untreated negation words will lead to errors in classification which in turn will decrease accuracy. This study applies the handling of negation words using First Sentiment Word (FSW) and Fixed Window Length (FWL) methods. The classification algorithms used are Naïve Bayes Classifier (NBC) and Support Vector Machine (SVM). In this work, we analized 1000 comments consisting of 390 positive comments and 610 negative comments. The results showed that the best performance of negation handling is FSW. This method has improved accuracy by 2.5% and F1 by 1.5% using NBC algorithm and has improved accuracy by 2.9% nad F1 by 3.4% using SVM algorithm.

The goal of CMMI (Capability Maturity Model Integration) adoption in project performance measurement is to enhance and optimize the Waste Bank Information System project's development process. Through the adoption of the CMMI's best practices and principles, the project team can increase the productivity and efficiency of project implementation. With improved risk identification and management, the project is less likely to encounter difficulties or fail. This is made possible by CMMI. The GAP Analysis assessment stage of the research process is used to determine how well Duri Kepa Village has followed the CMMI process. Next, the project's goals and scope are established. Finally, the CMMI process is mapped to the stages of implementation and process modifications in accordance with CMMI practices, as well as the process of performance monitoring and measurement. The aim of this study is to improve the project completion predictability for the Waste Bank Information System design and implementation in Duri Kepa Village. The project team will be better equipped to plan, coordinate, and manage project resources in order to promote project success by putting CMMI standards into practice.
