Abstract

The swift advancement of digital technology has prompted entrepreneurs to capitalize on social media as a promotional tool. Facebook stands out as a viable avenue for MSMEs given its extensive and devoted user demographic. Nonetheless, a disparity persists between the theoretical capacity of digital promotion and its actual execution, as numerous MSMEs have yet to optimize social media to substantially boost revenue. This investigation seeks to examine the impact of Facebook social media utilization on revenue growth at UMKM Griya Grosir, situated in Kampung Bina Bumi, Meraksa Aji District, Tulang Bawang Regency, Lampung Province. The employed research design is a quantitative approach featuring descriptive and associative characteristics. The study population comprises 30 data units encompassing revenue records, Facebook engagements, and repeat buyers, thereby designating the entire population as the analytical unit. Information was gathered via surveys, dialogues, record analysis, and direct inspection, subsequently examined through validity assessments, dependability evaluations, traditional assumption verifications, straightforward linear regression modeling, and hypothesis validation utilizing SPSS version 25. The outcomes demonstrate that Facebook social media utilization exerts a favorable and noteworthy impact on revenue growth at UMKM Griya Grosir. This is corroborated by a significance level of 0.000 (< 0.05), a determination coefficient (R²) of 0.733 or 73.3%, and a regression formula of Y = 12.456 + 0.589X. Aggregate revenue surged from 900 units to 1,920 units, reflecting a 113.33% escalation. This discovery validates that steady Facebook engagement, reinforced by content excellence, publishing regularity, and consumer engagement, can propel tangible revenue expansion for MSMEs. This investigation is anticipated to function as a strategic blueprint for MSME proprietors in cultivating more potent and enduring digital promotion.

Abstract

Education budgeting plays an important role in supporting school facilities, teacher needs, learning activities, and equitable access to educational services. However, differences in authority among provincial, city, and regency governments, as well as disparities in regional fiscal capacity, may affect the equitable distribution of education funding. This article aims to analyze the respective roles of provincial, city, and regency governments in education budgeting and their implications for equitable school services. It employs a literature review method by examining scientific articles on education budgeting, decentralization, school financing, and regional development planning. The literature is reviewed based on its relevance to the topic, particularly the division of authority, regional fiscal capacity, budget planning, management transparency, and school needs. The findings indicate that the division of authority provides the foundation for education budgeting but is insufficient to guarantee equitable school services. Regional fiscal capacity, accurate budget planning, transparent management, and the alignment of funding allocations with school needs also influence educational equity. Therefore, education budgeting should focus not only on compliance with budgetary regulations but also on delivering tangible benefits to schools and students.

Abstract

This study aimed to examine the effect of resilience on psychological well-being among firefighters in Kutai Kartanegara Regency, Indonesia. Firefighters are exposed to high job demands, hazardous working conditions, and repeated traumatic incidents, all of which may adversely affect their psychological state. In this context, resilience is considered a potential factor that enables individuals to adapt to stress and maintain psychological well-being. A quantitative approach with a non-experimental associative design was employed. The sample consisted of 162 firefighters from Kutai Kartanegara Regency who participated as respondents. Data were analyzed using simple linear regression. The results indicated that resilience had a positive and significant effect on psychological well-being, with a regression coefficient of 0.266 and a significance value of p = 0.021 (p < 0.05). These findings suggest that higher levels of resilience are associated with higher levels of psychological well-being among firefighters. The coefficient of determination revealed that resilience contributed 8.7% to the variance in psychological well-being, while the remaining 91.3% was influenced by other factors outside the research model. The findings underscore the importance of resilience as a psychological factor related to the well-being of firefighters.

Abstract

This community service study examines the role of communication psychology in fostering children's self-confidence through the “Lomba Islami Anak Ceria” (Cheerful Islamic Children's Competition) held at At-Taqwa Mosque, Gaden Village, Trucuk District, Klaten Regency. The program was initiated following observations that many early childhood and elementary school children attending local Quranic learning centers lacked self-confidence, felt shy, and hesitated to perform publicly. The study employed a participatory approach integrating communication psychology principles, supported by evaluation through direct observation and qualitative reflection. The program consisted of three stages: preparation through TPA mentoring, implementation of competitions, and evaluation. Activities included adhan recitation, Islamic quizzes, calligraphy coloring, short surah recitation, and interactive quizzes. Approximately 100 children from TPAs across Gaden Village participated, supported by 21 student volunteers. The results showed that friendly, empathetic, and supportive communication strategies, combined with equal appreciation for all participants, created a safe and comfortable social environment. Children demonstrated greater enthusiasm, more active participation, and increased courage in interacting and expressing themselves publicly. These findings highlight the importance of positive communication in supporting children's psychological development. This study concludes that a supportive environment grounded in communication psychology can effectively foster self-confidence in early childhood, particularly through engaging, inclusive, and enjoyable Islamic educational activities.

Abstract

CV Ziyad Aircond Indonesia determines the feasibility of used air-conditioning (AC) units manually, relying on technician experience without a standardized assessment procedure. This may lead to inconsistent assessments and suboptimal purchasing decisions. This study develops a web-based decision support system using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Data were collected through observation, interviews, and literature study, while the system was developed using the Prototype model. Six criteria were applied: compressor condition (weight 0.20), evaporator condition (0.15), condenser condition (0.15), unit age (0.15), brand (0.15), and price (0.20). TOPSIS processing includes decision matrix normalization, weighting, positive and negative ideal solutions, distance calculation,  preference values, and ranking. The calculation used ten used AC units with the same cooling capacity. AC010 achieved the highest preference value of 0.7393, followed by AC003 (0.6633) and AC001 (0.6418), while AC007 ranked last with 0.3556. Functional testing reported that tested features worked as expected, and user evaluation reached an overall score of 84.44%, categorized as very good in the thesis. The system provides structured recommendations to  support, rather than replace, the company’s final purchasing decision.

Abstract

Learning mathematics, especially measuring weight and standard units, remains difficult for third-grade students, and less varied instruction leaves them passive. This study aimed to determine the effect of the Project Based Learning (PjBL) model on the mathematics learning outcomes of third-grade students at UPTD SDN Telagabiru 1. It was a quantitative quasi-experimental study with a posttest-only control group design. The subjects were 43 students: 22 students of class III A in the experimental class (PjBL) and 21 students of class III B in the control class (conventional learning). Data were collected through a learning outcome test and analyzed using the Shapiro-Wilk test, Levene's test, and an independent sample t-test. The mean score of the experimental class (75.32) was higher than that of the control class (66.05). The data were normally distributed and homogeneous, and the t-test yielded a calculated t of 4.644, greater than the t table value of 2.020, with a significance value below 0.001. Therefore, PjBL had a significant effect on students' mathematics learning outcomes.
