Implementasi Geometric Brownian Motion dalam Memprediksi Harga Minyak Mentah pada Masa Pandemi Covid-19
No full textCrude oil has a vital role in the economic growth of a country, because crude oil is a source of energy driving the economy. To maintain economic stability, the price of crude oil in the coming period needs to be anticipated by making predictions on world crude oil commodity prices. One of the models that can be used to predict crude oil prices in the short term is Geometric Brownian Motion (GBM). The purpose of this study is to implement the GBM model in predicting crude oil prices during the Covid-19 pandemic, and to measure the accuracy of the model. In this study, the prediction of oil prices using the GBM model was carried out with 50, 100, and 1000 iterations. The results obtained indicate that the GBM model can work well in predicting crude oil prices during the Covid-19 pandemic. This is indicated by the MAPE value which is less than 10%
The relationship between well-being, social engagement, and the role of the state in realizing civic happiness
No full textHappiness is an important aspect of a country\u27s life, even in the study of public policy making happiness the main goal. Happiness comes from internal factors that come from personal motivation and motivation for something, while external factors come from various conditions outside of oneself, the focus in this research is external factors (such as government public policy). The problem of making public policy only limited to political decisions results in neglecting the happiness of citizens. This research aims to examine social aspects based on various previous studies that have contributed to citizen happiness. This research uses a qualitative approach with literature studies, materials derived from journals and books are the main sources used as units of analysis. The results show that social aspects, such as population, welfare, religion, social capital, and social engagement have an impact on happiness. Creating public space in developing various social aspects is an important thing that needs to be done so that citizens have broad access to develop themselves and feel happiness in the public space created by the state

Development of a hybrid reflective micro learning model based on ICT in Micro Teaching courses
No full textThis research aims to develop a hybrid reflective micro-teaching model. The research method used is a type of research and development referring to the Borg and Gall R&D Cycle. The research results from reflection sheets indicate that some students could perceive the teaching for themselves. This is evidenced by the correspondence between friend’s assessments and the results of their reflections. However, some students seemed less attuned to what was being taught. Peer observations and reflection on students’ learning indicate a promising potential for improvement in students’ selfassessment. For instance, some students reflected “good” in planning and implementing materials but couldn’t demonstrate their abilities accordingly. Limited trials of the Reflective Microteaching model indicate a tendency for students to respond positively to the model. Observations using various instruments also show an inclination toward better understanding and increased awareness of learning planning and implementation. Nonetheless, there are still discrepancies between reflection results and friends’ observations

Women\u27s Alternative Media: Agents of Change on the Issue of Women\u27s Roles in Indonesia
No full textProgress in achieving gender equality and empowering women in Indonesia has been too slow and fragmented. The media can provide a voice and a platform for placing women\u27s role issues on the development agenda. As in the education, health, economic, labor, and political sectors. However, in reality, there is a significant gender gap in mainstream media companies so that women are not represented optimally and steps to improve gender equality are limited. Alternative media is very possible to take a role in explaining issues of gender equality and women\u27s empowerment. Because this type of media can connect various sectors, including trade unions, social movements, organizations and various elements of society. Researchers use the concept of gender and communication development, Standpoint theory, and alternative media. The approach used in this study is literature review research methodology. The results of this study explain that journalists in alternative media consider gender awareness and sensitivity important in themselves to be able to protect and defend women\u27s interests. In fact, alternative media provide wide opportunities for journalists to raise strategic issues of equality and women\u27s empowerment
