The Industrial Revolution 4.0 on Education in Indonesia affects school activities rapidly. Teachers are no longer educated in classrooms only, but they can also utilize technology to conduct distance learning. One interactive application that can be used as a form of question exercise is Quizizz. Therefore, this research aims to: first, examine the effectiveness of students' activities by using Quizizz on mathematical problem-solving skills; second, investigate the differences in the increase in students' ability to solve mathematical problems between the class with and without the Quizizz-aided learning method; third, describe the activities of students who used the Quizizz-aided drill learning method; and fourth, describe the students' responses in using Quizizz. The research was quasi-experiment with a pretest-posttest non-equivalent control group design. The participants in this study are 67 of Grade10 students divided into experimental and control classes. Data collection techniques used were tests for students' mathematical problem-solving skills and questionnaires. The instruments were validated using Pearson correlation, while the reliability was tested using Cronbach's Alpha. Then, the N-gain test was used to analyze the data. The results showed that there was an effect on students’ learning activities by using Quizizz on their problem-solving skills. Besides, there was a difference in the improvement of problem-solving skills between the class with and without Quizizz-aided. Furthermore, students’ activities in three meetings have increased. Moreover, students provided a positive response in learning using Quizizz. Thus, it can be concluded that Quizizz is effective in improving mathematical problem-solving skills.

Writing serves as a tool for students to extend their grammatical composition, enrich their lexicon, and increase other language abilities, such as reading, listening, and speaking.  This study intends to examine written features and analyze frequent errors of students' grammar in writing. Employing a qualitative descriptive research method, the samples were chosen based on convenience samples. The participants were high schoolers studying at their Year 10, whose English language competence is at an average grade. The students practiced descriptive writing and grammar rules. Four students submitted their essays analyzed using content analysis. The assessment criteria were analyzed using a framework of grammatical errors by James (1998), which classify errors into nine (9) categories (prepositions, articles, singular/plural, adjectives, irregular verbs, tenses, concord, possessive case, and passive/active). The study found 73 errors in students’ writing. The top three errors found were prepositions, articles, and tenses, in a particular order. The next identified errors were singular/plural, concord, possessive case, and irregular verbs.  Some pedagogical implications deriving from the study were also highlighted. The present study suggests the need for EFL teachers to improve their skills in marking and giving feedback toward student writing. This will, in turn, improve students’ writing skills.

The purpose of this study is to find out what variables affect employees who tend to leave or stay in the company. In this study predicted workplace bullying, workplace spirituality and self esteem, affect employee turnover. Subjects in the study were 206 stewardesses who were obtained by accidental sampling technique. Test the validity of measuring instruments using confirmatory factor analysis (CFA) techniques. Data analysis uses multiple regression analysis techniques. The results showed that there was a significant effect of workplace bullying, workplace spirituality and self-esteem on turnover intention. Minor hypothesis test results show that inner life and meaning and purpose in work significantly affect turnover intention. In contrast, work-related bullying, person-related bullying, physical bullying, and self-esteem are not significant in influencing turnover intention.

This study aims to 1) analyze the effect of research variables on the volume of Indonesian banana exports partially and 2) Analyze the effect of research variables on the volume of Indonesian banana exports simultaneously. The scope of this research focuses on the export of Indonesian bananas with the Harmonized System (HS) code 0803. The data used in this study is secondary data from 2004 to 2018. Data was sourced from UN Comtrade, World Bank, Central Statistics Agency (BPS), Ministry of Agriculture, Bank Indonesia, and other websites related to this research. The method used in this study is multiple linear regression analysis with the help of SPSS 25 software.Based on the results of the study, the Banana Export Volume (VEP) has fulfilled the classical assumptions, and partially the factors that significantly affect the banana export volume are exchange rate variable and the factors that do not significantly affect the banana export volume are the national banana production and the export price of bananas. Overall (simultan) the factors consisting of national banana production, banana export prices, and the rupiah exchange rate significantly affect the volume of banana exports. The coefficient of determination (R2) in the VEP model is 0.737. Keywords: banana, export, multiple linear regressionAbstrak:Tujuan penelitian ini adalah untuk 1) Menganalisis pengaruh variabel penelitian terhadap volume ekspor pisang Indonesia secara parsial 2) Menganalisis pengaruh variabel penelitian terhadap volume ekspor pisang Indonesia secara simultan.

Sedangkan secara keseluruhan (simultan) faktor-faktor yang terdiri dari produksi pisang nasional, harga ekspor pisang, dan nilai tukar rupiah berpengaruh nyata terhadap volume ekspor pisang Indonesia.  Kemudian diketahui bahwa koefesien determinasi (R2) pada model VEP  sebesar 0,737. Kata kunci : pisang, ekspor, regresi linear berganda

In facing the challenges of modern times, parents need to adapt their approach to their children in shaping social values in the millennial generation. The role of parents and family is vital. Millennials tend to learn through hands-on experience, so parents can use everyday opportunities to demonstrate desirable social values. Open communication, such as open discussions, is important between parents and millennial children. According to Emile Durkheim, the social structure consists of values and norms, defined as cultural systems that become important behavioral guidelines according to the prevailing social environment. According to James M. Henslin, social structure is divided into several elements: social groups, social institutions, social rules/norms, and social and cultural stratification. The focus of this research is related to social values. This study aims to investigate the role of parents in forming social values in the millennial generation. The research method used is qualitative with a descriptive approach in the form of facts or phenomena that parents have an essential role in shaping social values within the millennial generation's social structure. This study uses qualitative methods to understand parents' experiences and perspectives in shaping their children's social values. The study results show that parents play a vital role in shaping the social values in the millennial generation's social structure.
