<![CDATA[Indonesia is a country located in the Pacific Ring of Fire, because of this Indonesia is vulnerable to earthquakes because it is located at the meeting point of several colliding tectonic plates. In addition, the presence of active volcanoes is also an additional factor. The construction of high-rise buildings in Indonesia has continued to increase in recent years along with the growth of urbanization and the need for more efficient space in urban areas, this has increased the risk of accidents in high-rise buildings. With these problems, a disaster simulation is needed which can be the right step to understand the correct ways to handle and evacuate from disasters. The right simulation for this problem is to use Virtual Reality (VR)-based learning because this simulation can increase the effectiveness of disaster management education by experiencing firsthand a realistic and interactive earthquake scenario simulation. The results of the pre-post test processed using the Wilcoxon signed rank test method obtained a result of 7.5 where 7.5 ≤ 52 (critical value) concluded that this simulation provides a significant change in knowledge of earthquake disaster mitigation in high-rise buildings. And from the SUS (System Usability Scale) Questionnaire, the score obtained was 78.875 which is included in the category 70-85 which means that this system is quite good in terms of usability. Users generally feel comfortable using the system.]]>

<![CDATA[In providing funding for toll road development projects, many developing countries are im-plementing PPP pro-curement schemes including Indonesia. This funding scheme is believed to be an innovative procurement process model and has good prospects for the future of the construc-tion industry in the world. However, in its implementation, the Indonesian government is currently faced with various problems that have the potential to have a negative impact on the management and development of toll roads in Indo-nesia. Therefore, the main objective of this research is to develop a method of evaluating the success of PPP-themed toll road projects and determining the current and future strategy of PPP-themed toll road development projects. Methodology This research, using an exploratory sequential mixed methods approach, involves four stages of research. Through a Systematic Literature Review (SLR) of reputable scientific journals from various countries, a questionnaire survey was developed. The survey results were analyzed using multivariate statistical methods with the help of Par-tial Least square analysis software (PLS-SEM), analytical hierarchy process (AHP) and Relative Importance Index (RII) methods. The results of this research found 20 critical success indicators and four dimensions of project success. This study produces a new way to assess the success of PPP-themed toll road projects that is very important and can inspire the government in making policies, legislation and regulations as well as innovative strategies in develop-ing PPP-themed toll roads.]]>

<![CDATA[This study examines the business strategies applied by millennial entrepreneurial students in Sidenreng Rappang Regency, South Sulawesi. These students are engaged in various business sectors such as food and beverages, fashion, cosmetics, services, art and design, and digital business. The primary purpose of the study is to analyze the strategies used in responding to business opportunities, competitive advantages, contributions to entrepreneurship learning in higher education, and obstacles and solutions faced by students. With a qualitative phenomenological approach, this study explores the experiences of young entrepreneurs in taking advantage of market opportunities that other entrepreneurs often ignore. Students utilize business model innovation theory by considering factors such as understanding consumer behavior, product differentiation, service quality, and location and network. Entrepreneurship learning in higher education makes an essential contribution to equipping students with an understanding of business strategies and their application in actual practice. Of the ten respondents, five have participated in entrepreneurship seminars and training, while the other five are self-taught and through campus activities. These two methods are considered influential in shaping entrepreneurial skills and mindsets. The challenges faced by millennial entrepreneurs, as well as the solutions they implement, show relevance to modern management theory.

<![CDATA[The current problem is that the attendance process at SMA Negeri 1 Rantau Pulung is still done manually. This becomes a problem when the attendance book is lost or exposed to water, which causes the writing on the attendance book to become blurry. The impact that could occur if the attendance application is not made is that SMA Negeri 1 Rantau Pulung will continue to carry out the attendance process manually and could be affected by the problems mentioned previously. Another impact is being left behind in the field of technology in the current era of digitalization. The step in solving the problem was that the researcher contacted the principal of SMA Negeri 1 Rantau Pulung to offer a presence application, then the researcher asked for the data needed to build the presence application. The temporary results currently obtained are that the presence application has been successfully developed and can now carry out the attendance qrcode scanning process. The conclusion from the interim results of this research is that web and mobile based attendance applications have been successfully developed. The presence application can generate QR codes on the web and can scan the generated QR codes via a mobile application.]]>

<![CDATA[Global problems related to the greenhouse effect and global warming have pushed research towards clean energy sources. One of the technologies of concern is wind turbines, whose performance is highly dependent on the aerodynamics of the airfoils used. This study aims to analyze the effect of input speed variation on the aerodynamic performance of NACA 4418 airfoil using gurney flap as a passive flow method. In this study, the Reynolds Averaged Navier-Stokes (RANS) method was used to calculate aerodynamic parameters, by varying the height of the gurney flap on the trailing edge of the airfoil. The results showed that the use of gurney flaps with flap height variations of 1%, 2%, and 3% of chord length was able to significantly increase the lift coefficient, with the highest increase at the flap height of 3% c. In addition, this passive method has proven to be efficient in improving aerodynamic performance without the addition of an active control system. In conclusion, variations in input speed and flap height can improve the aerodynamic performance of NACA 4418 airfoils, making this method feasible to apply to wind turbines.]]>
