Qualitative studies regarding the reception or reception of Generation Z on Covid-19 information in Indonesia have not been widely carried out. As a generation that was born and grew up with digital technology that is developing very quickly, Gen Z has different characteristics from other generations. Gen Z's acceptance of information related to Covid-19 is one of the important things to assess regarding their potential role and quantity. This study aims to explore Gen-Z's acceptance of Covid-19 information in digital media with a qualitative approach to reception analysis. Data were obtained through FGDs and in-depth interviews. Research findings show that Gen Z prefers access to information that is fast-paced and practical; have a preference for news that is more relaxed, positive and informative; have adequate information literacy to identify hoaxes and perform fact checks; and has a reading position of negotiation and opposition with diverse behavior, but not hegemony-dominant. The results of this study contribute to the qualitative data of Gen-Z reception of Covid-19 information among the available quantitative data.

Mangrove ecotourism has an important role in maintaining the balance of coastal ecosystems. Mangroves have various important benefits, such as in mitigating climate change with their ability to absorb carbon and protect coastal areas from abrasion. To improve tourism development, the Geographic Information System's ecotourism suitability analysis has become an important instrument. The purpose of this study is to explore mangrove types and the value of the Tourism Suitability Index. A Geographic Information System (GIS) and Tourism Suitability Index (TSI) approach was used to analyze parameter data, including mangrove density, species richness, mangrove thickness, tides and association biota. Results show that the dominant mangrove species are Xylocarpus granatum, Rhizopora mucronata, Rhizopora apiculata, and Bruguiera parviflora, with densities varying from 4 m²/ind to 23 m²/ind. Mangrove thickness varied from 500 meters, and biota association varied from 1 to 4 groups. The average tides vary in height, providing an important hydrological context. The land suitability analysis showed great mangrove ecotourism potential in Kemboja Village, with 2,532.20 hectares classified as highly suitable (46.07%) and 2,961.86 hectares classified as suitable (53.89%) for sustainable tourism development. Unsuitable areas cover 1.61 hectares (

A mother who decides to work often experiences role conflict because she cannot divide her time to carry out her roles, both as a mother and worker, which can cause stress and low life satisfaction. This has an impact on her subjective well-being. Subjective well-being is a person’s evaluation of their life, including life satisfaction, experienced emotions, and fulfillment. The social support of a spouse or husband is one of the variables that influence it. Therefore, this study aims to determine how much influence the husband’s support has on the subjective well-being of working mothers. This study uses a quantitative design with a simple regression analysis calculation method. The number of samples in this study was 140 participants who were actively involved, obtained through the purposive sampling technique. The scale used to measure the husband’s support was Receipt of Spousal Support Items, while the scale to measure subjective well-being used the Satisfaction with Life Scale (SWLS) and Positive Affect Negative Affect Schedule (PANAS). This study shows that there is an influence of the husband’s support on the 3 aspects of subjective well-being in working mothers with the value of p < 0.01. p (1, 138) = 64.11, F = 0,317, 2R < 0.01 The husband’s support also explained a significant proportion of the variation in positive aspect scores, (138) = 0.027, t= 0.217 p < 0.01. p (1, 138) = 52.71, F = 0,276, R2 < 0.01 The husband’s also explained a significant proportion of the variation in positive affect scores, (138) = 0.038, t= .278. p < 0.01. p (1, 138) = 71.10, F = 3,40, R2 < .01. The husband’s also explained a significant proportion of the variation in negative affect scores, (138) = 0.042, t = 0.-353. The implication of the findings of this study is that the husband’s support is able to balance emotions in a working mother so as to create satisfaction in life, which is an aspect of forming subjective well-being.

Mathematics is a field of study needed in various aspects of life. Accordingly, mathematics should always be considered a compulsory subject at every level of education, including in Islamic Boarding Schools. The fact shows that implementing mathematics learning in several schools needs to run optimally, especially in schools lacking teachers and limited educational facilities and infrastructure, such as The Al Ashry Islamic Boarding School, at the secondary level in Padang. This condition indicates that it is necessary to assist other parties to help students in their mathematics learning process. For this reason, the community service team of The Mathematics and Science Data Department of Andalas University conducted an intensive mathematics tutoring activity for The Al-Asyri Boarding School students. The activity carried out during September-December 2022 combined the lecture and the small group discussion approach. From the evaluation delivered by the students at the end of the activity, it can be concluded that this activity increased students’ interest, motivation, efficacy, and understanding of mathematics subject.

The aims of this study was to conduct a literacy campaign in a second group of Idolmaster primary schools and to identify factors that hinder and support literacy campaigns. A descriptive qualitative survey was used as the survey form. The subjects of this study were students, principals, and reachers. The data collection methods used by the researchers were observations, interviews, and recordings. Data analysis techniques use Miles and Huberman's qualitative models to reduce, present and draw conclusions from data. It was found that the implementation of the Seggas II Idolmaster Primary School Literacy Campaign is still in the stage of specialization or familiarization. Interviews and observations by researchers confirm this.

This study empirically explores the dynamic interactions between the European and Indonesian cocoa markets during the 2008 global financial crisis (GFC) and the 2011 European debt crisis (EDC) using a battery of time series approaches of cointegration and multivariate Granger causality. The study documented a long-run equilibrium between the European and Indonesian cocoa markets, implying a reciprocal relationship. However, an inefficient adjustment transmission in the Indonesian cocoa prices was recorded throughout the study. The US currency constantly influenced Indonesian cocoa prices, while cocoa markets were independent of fluctuations in world oil prices. Overall, the study recorded a different level of the speed of adjustment of short-run imbalances to long-run equilibrium in the domestic cocoa market across economic crises.
