This literature study examines the influence of teacher competence on student learning outcomes at various levels of Senior High Schools (SMA) in Indonesia. To improve student learning outcomes, teachers must be able to develop their competence in every learning process. The teacher competence in question includes pedagogical, professional, social, and personality competence. This study applies the literature review method through analysis of various relevant scientific sources. The results of the study revealed that teacher competence influences the improvement of student learning outcomes, although in some cases there are other variables such as student learning motivation and learning facilities that also contribute. Therefore, improving teacher competence needs to be a concern in efforts to improve the quality of education.

Productivity is one of the major issues facing Iraqi educational institutions, and it can be identified by examining the factors that influence it. Work-life balance is one of the key elements affecting the productivity of companies that rely heavily on human resources. Therefore, the purpose of this study was to examine how WLB affects employee productivity in Iraqi educational institutions. The study used a quantitative, cross-sectional, and correlational methodology. Every employee in academic institutions in Iraq who worked in the educational departments of the Maysan Education Directorate was included in the statistical population. Using random sampling and variance calculations, the sample size was calculated to be 200. A standard productivity questionnaire based on the ACHIEVE (1980) model and two work-life balance questionnaires by Wang and (2009) served as data collection tools for the study. Expert opinions were used to validate the questionnaires in terms of form and content, and Cronbach's alpha coefficient was used to assess the reliability of the instrument to be greater than 0.7. Smart PLS and SPSS 22 software were used for analysis. The results showed that employee productivity was affected by all elements of work motivation.

This research was explanatory research with quantitative research. The variables were Brand Image (X1), Lifestyle (X2) and Purchase Decision (Y). The population in this research were the consumers who made direct purchases at Azura Coffee Malang. The Data collection was done throught observation and questionnaires to 80 respondents with the purposive sampling method. The data analysis of this research used descriptive analysis, validity test, reliability test, classical assumption test, and hypothesis test. The results of multiple linear regression analysis showed the equation Y = 4,758 + 0,261X1 + 0,547X2 + e with a coefficient of determination of 0,652. This showed that there was a significant effect of variables X1 and X2 on variable Y of 65,2%, while the remaining 34,8% was influenced by other variables not examined in this research. The results of the partial test of the Brand Image variable obtained was t count 2,146 > t table 1,66488 and Lifestyle variable was t count 5,620 > t ttable 1.66488 while the results of the simultaneous test F count was 75,119 > F table 3.12. Based on the research results, it can be concluded that Brand Image and Lifestyle variables partially or simultaneously have a positive and significant on the purchasing decisions at Azura Coffee Malang.

This study analyzes the strategies used by educators to improve learning motivation of mentally retarded students at SLB Negeri North Sumatra. The method used is descriptive qualitative, with data collection through observation, semi-structured interviews, and documentation. The subjects of the study consisted of mentally retarded class teachers and seven students with varying levels of difficulty. The results showed that students' learning motivation varied, with some students showing enthusiasm for fun and relevant activities. The five main strategies applied by teachers include: (1) individual and contextual learning strategies with an emphasis on the learning by doing method, (2) the use of varied learning media such as visual media, flashcards, learning videos, and interactive applications, (3) giving rewards in the form of verbal praise and small prizes and proportional educational punishments, (4) creating a safe, comfortable, and supportive learning environment with positive communication, and (5) active cooperation with parents through communication. The main supporting factors are teachers, a school environment, and good relationships with parents, while inhibiting factors include low parental awareness and students' socio-economic conditions. The success of the strategy can be seen from the increase in more active student behavior. This study concludes that the learning motivation of mentally retarded students can be increased through an adaptive approach that involves all parties.

Drug packaging not only serves as a protective barrier for pharmaceutical products but also functions as a strategic element in conveying information and ensuring consumer rights. This study is a literature review of five journals that discuss packaging innovation, legal aspects of labeling, consumer protection, and packaging design from both technological and regulatory perspectives. The aim of this study is to compare the dimensions of innovation, information, and protection in drug packaging. A narrative review method with a qualitative descriptive approach was used. The results show that innovations such as the use of adsorbent plastic and efficiency in packaging systems significantly affect product stability and production speed. Meanwhile, the inclusion of composition details and halal labeling on packaging serves as a form of consumer protection from health risks and rights violations. It is concluded that a multidimensional approach to drug packaging is essential in creating a pharmaceutical distribution system that is efficient, safe, and ethical.

Gen-Z has grown alongside rapid technological and digital media development, fostering frequent virtual interactions over face-to-face ones. This shift often triggers Fear of Missing Out (FOMO), where individuals feel anxious about missing trends or updates. Among Gen-Z, FOMO is strongly influenced by social media, driving consumptive behavior. This article explores how FOMO creates opportunities for Indonesian Micro, Small, and Medium Enterprises (MSMEs) through jasa titip (personal shopping services). Using the Dubai Chocolate trend as a case study, it highlights how social media-driven demand has spurred interest in personal shopping services to source and deliver such products. The research emphasizes the importance of social media as a tool for MSMEs to tap into FOMO-driven markets. It also encourages MSMEs to innovate by offering affordable, locally sourced alternatives to remain competitive. This approach enables MSMEs to thrive in a dynamic, trend-focused digital landscape.
