This study investigates the impact of digital gamification on employee motivation, engagement, and productivity in technology companies. Gamification, which integrates game design elements such as rewards, badges, and leaderboards into non-game environments, has gained popularity as a tool for enhancing employee performance in workplaces. The research employs a quantitative survey methodology to gather data from employees in technology firms that have implemented gamified systems. The findings reveal that gamification significantly increases employee motivation by tapping into intrinsic motivators such as autonomy, competence, and relatedness. Employees reported higher levels of engagement, with many attributing their increased participation to the fun and competitive nature of gamified tasks. Additionally, productivity improvements were observed, particularly among employees in roles that require individual performance, such as software engineers, where autonomy and goal-setting were key factors. The study also identifies variations in the effectiveness of gamification based on factors such as job role and organizational culture, emphasizing the need for customization to suit different employee needs. Despite these positive outcomes, challenges such as employee resistance, poorly designed systems, and resource constraints were noted as barriers to successful gamification implementation. These findings suggest that gamification is an effective strategy for improving motivation and engagement in technology companies but requires thoughtful design and alignment with company culture to maximize its impact. Future research should explore the long-term effects of gamification and examine how specific elements, such as leaderboards and rewards, influence employee behavior across different demographics.

History opens a window to the past to welcome the future, learning history will help to know and understand how the history of the past and also the people associated with these events. Studying history not only aims to know important events or events in the past but also teaches various forms of experience that occur both success and failure. Every human being needs education and knowledge because it is for human development itself. Through education, humans not only get teaching about special skills but also something deeper, namely science. In the world of education through learning, students gain knowledge and learn what is obtained through learning. Each student will pass the evaluation stage. The evaluation is given after students have gone through several learning and understanding processes and then given questions, both essays and multiple choice questions, in order to help the learning process in the classroom. To maximize the use of multiple choice as a learning tool, students can choose it with consideration in the answer choices that have been determined. Teachers give assignments to students to work on multiple choice questions in two ways, the first is to solve multiple choice questions, when given an assignment during class hours to submit it to the teacher when the subject is finished. Alternatively, the teacher can give the students an assignment or homework and collect it during the next meeting. Research shows that teachers prefer the use of multiple choice questions, not only because of administration, time saving and simplicity but also because they are objective and consistent. Furthermore, students based on the results of the study prefer giving multiple choice questions because they can eliminate answer errors and the questions on multiple choice questions are more objective than others.

The utilization of coal as a fossil fuel causes several ecological problems, as for the consequences of the coal combustion process, namely pollution and emissions. Combustion of high sulfur coal produces sulfur dioxide gas (SO2). This sulfur dioxide (SO2) will become H2SO4 (sulfuric acid) which can directly or indirectly disrupt human life, such as causing acid rain, causing tightness in the respiratory tract and causing corrosion and shortening the life of factory equipment. To reduce SO2 gas, a reduction in sulfur content is carried out before combustion which is called desulfurization. This research was conducted using the leaching method with variations in leaching agent and solution concentration. Leaching agents used in this study are NaOH and HCl. The coal to be desulfurized is coal from PT Anugerah Krida Utama with an initial total sulfur content of 4,05% adb. 10 grams of coal with a size of 0,212 mm was leached with 250 ml of chemical solution using a hot plate stirrer at 80˚C and 250 rpm for 1 hour. The results showed that the optimum condition for leaching agent NaOH occurred at a concentration of 8 M showing the initial total sulfur content of 4,05% adb decreased to 1,69% adb with a maximum percentage decrease of 58,27% and at leaching agent HCl the optimum condition occurred at a concentration of 1 M showing the initial total sulfur content of 4,05% adb decreased to 2,91% adb with a maximum percentage decrease of 28,14%.
