Public Elementary School 5 Sawojajar Malang is the site of this descriptive qualitative study. Interviews and a review of relevant literature were the primary methods of data collecting for this research. The purpose of this research was to identify many issues with online education during the COVID-19 epidemic. Teachers have challenges in online learning due to the lack of control and assessment tools available to them. Some students are less engaged in their learning, leading to boredom and apathy, and there is a shortage of facilities that may be utilized for online learning</em></p> Almira Zahra Mauliadini Almira Zahra Mauliadini Copyright (c) 2024 Almira Zahra Mauliadini Almira Zahra Mauliadini https://creativecommons.org/licenses/by/4.0 https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/301 Fri, 27 Sep 2024 00:00:00 +0000 The Impact of Using Online Loans on the Consumptive Lifestyle of Students at the Sepuluh Nopember Institute of Technology, Surabaya https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/315 <p><em>This research aims to analyze the impact of using online loans on the consumer lifestyle of students at the Sepuluh Nopember Institute of Technology (ITS) Surabaya. The research method used is quantitative through online surveys with purposive sampling data collection techniques. This research uses data from 53 respondents who are students at the Sepuluh Nopember Institute of Technology (ITS) Surabaya who are also online loan users. The research results show that ITS students who also use online loans tend to be consumptive and often buy goods without considering finances and needs just to improve their social status or because they are on sale. Consumptive behavior without considering needs and finances can have negative impacts in the long term, such as being in debt, having difficulty focusing on studies due to financial problems, and other problems in the future.</em></p> Farel Danendra, Muhammad Daffa Alvinoer Rahman, Baringga Aurico De Erwada, Nur Aini Rakhmawati Copyright (c) 2024 Farel Danendra, Muhammad Daffa Alvinoer Rahman, Baringga Aurico De Erwada, Nur Aini Rakhmawati https://creativecommons.org/licenses/by/4.0 https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/315 Fri, 27 Sep 2024 00:00:00 +0000 Causality Model of Trading Variables Between Trading Volume, Bid-Ask Spreads, and Stock Return Volatility (Case Study: Bisnis-27 Index) https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/317 <p><em>This research explores the causality model between trading volume, bid-ask spread, and stock return volatility in the business index-27. Utilizing historical data, Granger causality analysis is employed to determine the direction and strength of the relationships between these variables. The findings reveal significant causal relationships among trading volume, bid-ask spread, and stock return volatility. These findings offer valuable insights into understanding stock market dynamics and their implications for investment decision-making. Moreover,This article contains an analysis of the relationship between stock trading variables within the scope of two main hypothesis namely the mixture of distribution hypothesis (MDH) and the sequential information arrival hypothesis (SIAH). The calculation results identify that for most stocks there is a one way Granger causality relationship between trading volume and return volatility, which is not sufficient evidence to support the MDH theory. </em></p> Andi Agung, Arfatuz Zaqiyah, Muhammad Rozikin, Moh.

The analysis results show that the type of platform (Instagram or TikTok) does not have a significant impact on follower interest. However, posting frequency is proven to have a substantial influence, with weekly frequency showing the most positive impact. The interaction between platform type and posting frequency does not demonstrate a significant effect. These findings suggest that content creators can focus on adjusting their posting frequency, particularly with a weekly schedule, to increase follower interest, without needing to worry about choosing between Instagram or TikTok platforms.</em></p> Nabila Azzahra, Bulan Purnama Utami, Adamsyam Arrafi, Vitri Aprilla Handayani Copyright (c) 2024 Nabila Azzahra, Bulan Purnama Utami, Adamsyam Arrafi, Vitri Aprilla Handayani https://creativecommons.org/licenses/by/4.0 https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/381 Fri, 27 Sep 2024 00:00:00 +0000
