Motorcycle engine performance is highly dependent on the air intake system, which plays a crucial role in the combustion process. One common method for improving engine performance is modifying the intake system, either by installing additional devices or adjusting the quantity of incoming air. One innovation that is starting to be widely used is the Jet Ranger, an additional device on the intake duct that is claimed to be able to increase air flow into the combustion chamber. This study aims to determine the effect of the use of Jet Ranger and variations in the quantity of incoming air on the maximum power of a 150 cc motorcycle engine, as well as to analyze the interaction between the two variables. The study was conducted using an experimental method with a two-way factorial approach. The independent variables in this study consisted of two factors, namely the use of Jet Ranger (without Jet Ranger and with Jet Ranger) and variations in the quantity of incoming air divided into four levels (0.008; 0.012; 0.016; and 0.020 kg/s). Maximum power testing was conducted using a Leads dynotest, while the mass of incoming air was calculated based on air velocity measured using a digital anemometer. The test data were statistically analyzed using a two-way ANOVA to identify the effect of each factor and the interaction between them on engine power. The results of the study indicate that the use of Jet Ranger significantly increases engine power. Variations in the quantity of intake air also significantly affect the power generated. In addition, the interaction between the use of Jet Ranger and the quantity of intake air is proven to have a significant impact on increasing the maximum engine power. These results are in line with the theory of intake systems which states that increasing optimal air flow can increase the volumetric efficiency of the engine, and are supported by findings from previous studies. Therefore, these findings can be used as a reference in the development of air intake systems on motorcycles to achieve more optimal engine performance.

This study aims to analyze the factors influencing economics teachers' behavioral intentions to use Generative Artificial Intelligence (GAI) in teaching, using the Unified Theory of Acceptance and Use of Technology (UTAUT) as the foundational framework. The respondents of the study were high school economics teachers in Semarang City, Central Java, Indonesia. Data were collected from 119 respondents using the accidental sampling technique. A questionnaire developed by previous researchers was used to gather research data. Structural Equation Modeling-Partial Least Squares (SEM-PLS) was employed as the data analysis method. The findings indicate that performance expectancy, effort expectancy, social influence, and facilitating conditions significantly determine the level of teachers' intention to use GAI in teaching. Furthermore, the Technological Pedagogical Content Knowledge (TPACK) variable serves as a moderating variable in the research model. The practical implications of this study suggest that educational institutions, teachers, and policymakers need to enhance understanding, provide training, and implement policies that support the integration of TPACK-based Generative AI. These efforts aim to encourage the effective use of this technology to improve the quality of teaching and learning.

During the globalization age, culturally and ethnically diverse organizations are increasing. To overcome differences and create a harmonious and productive work environment, inclusive leadership is essential. In student organizations, leadership plays an important role in producing effective teams. In the context of the diversity of student organization members of STIE Mahardhika Surabaya, this study attempts to explain how inclusive leadership practices affect team performance. This study conducted a descriptive qualitative study involving observation, documentation, and in-depth interviews and research on two student organizations, UKM Jurnalistik and PMII. The study showed that an open inclusive leadership style in UKM Jurnalistik was able to increase two-way communication, member participation, and a sense of belonging to the organization, which had a positive impact on team performance. Meanwhile, a more structural but still inclusive leadership style in PMII was also able to increase two-way communication, member participation, and a sense of belonging to the organization.

This journal discusses the impact of TikTok's $1.5 billion USD acquisition of Tokopedia shares. Following the closure of TikTok Shop in Indonesia due to licensing issues, ByteDance (TikTok's parent company) re-entered the Indonesian e-commerce market through an investment in Tokopedia. This acquisition has sparked speculation about the collaboration and its impact on Indonesia's digital industry. Tokopedia will manage TikTok Shop in Indonesia, while TikTok will continue to operate as a social media platform. Concerns have arisen about potential monopoly and China's geopolitical influence, given ByteDance's close ties with the Chinese government. Issues of data ownership and security have also been highlighted as serious threats. This article emphasizes the importance of vigilance against foreign influence and its impact on Indonesia's economic sovereignty, drawing parallels to historical experiences such as the Trojan Horse, which illustrates the dangers of complacency.

This research aims to examine the relationship between independent variables, including: Current Ratio,Return on Assets, Debt to Equity Ratio and the dependent variable Stock Price, with the moderatingvariable in this research being Total Assets. Research was conducted on 12 infrastructure companies listedon the Indonesia Stock Exchange (BEI), using non-probability sampling techniques-quota sampling in theperiod 2018 to 2022, a period of 5 years. This study explored whether having good fundamentals wouldhave a direct effect on price increases. the shares of the issuing company are moderated by the condition ofthe company's total assets. The findings of research studies on infrastructure companies show that theCurrent Ratio, if it stands alone, will have a positive effect on share prices, but if it is moderated by totalassets, it will have a negative effect on share prices. Return on Assets has no effect if it stands alone, but ifmoderated by Total Assets then Return on Assets has a positive effect. Debt to Equity Ratio has no effect onshare prices, whether alone or moderated. Simultaneously in this research study, Current Ratio, Return onAssets and Debt to Equity Ratio, moderated by Total Assets, have an effect on stock prices. This study offersa regression analysis on infrastructure companies, the results provide a basis for future research in thisarea. And company management can provide information about the relationship between fundamentalfactors and the company's share price which is moderated by total assets.
