Abstract

Early Childhood Education is the main foundation in shaping the quality of human resources in the future. However, investment in Early Childhood Education infrastructure is still considered a cost burden, not a strategic opportunity. This study aims to examine in depth the technical economic values of Early Childhood Education infrastructure development amidst the demands of sustainable development. This research uses a descriptive-qualitative case study approach and technical economic feasibility analysis methods in the form of Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Benefit-Cost Ratio (BCR). The results show that the development of Early Childhood Education infrastructure in the study area has a positive NPV, an IRR higher than the discount rate, and a PP below the building's operational period. In addition, a BCR value > 1 indicates that the investment is feasible and has a broad impact. These findings prove that small investments in Early Childhood Education infrastructure not only produce long-term social impacts but also provide tangible economic value. Therefore, the integration of technical economic principles in Early Childhood Education development policies needs to be a priority to address the challenge of poverty in basic education in Indonesia. This study strengthens the argument that education is not simply a social expenditure, but also a long-term investment that provides tangible returns for society and the country.

Abstract

This study aims to analyze the needs and opportunities for implementing Community Learning Centers (CLCs) to support the development of community education in South Papua. The existence of CLCs in the region remains limited, despite their crucial role as non-formal learning institutions that can reach communities with diverse social, economic, and cultural backgrounds. This research employs a qualitative approach using interviews, observations, and documentation studies as data collection techniques. Informants include community leaders, educators, government officials, and residents who are the target of community education programs. The findings reveal a significant need for CLC implementation, particularly in literacy eradication, vocational skills improvement, digital literacy, and entrepreneurship development. Furthermore, there are substantial opportunities to establish and expand CLCs through local government support, collaboration with higher education institutions, and partnerships with community organizations. The study concludes that CLCs are an effective strategy to expand access to non-formal education, strengthen community empowerment, and contribute to sustainable development in South Papua.

Abstract

This community service activity aimed to improve the production capacity, financial management literacy, and digital marketing skills among members of the Family Welfare Empowerment group in Matara Village by developing fish nuggets as a value-added processed product utilizing local fisheries potential. The program was implemented using a participatory approach through educational and training activities, including program socialization, fish nugget production training, simple financial management training, and digital marketing training. The activities were conducted at the Matara Village Hall and involved 20 participants from the local community group. The results indicated a significant improvement in participants understanding of hygienic production techniques, their ability to maintain simple financial records, and their use of social media as a platform for product promotion. The integration of production training, financial management, and digital marketing also encouraged the development of household enterprises utilizing fisheries products and expanded opportunities for marketing processed products. This activity contributed to strengthening the capacity of community-based enterprises and supported the development of economic independence through the utilization of local resource potential in Matara Village.

Abstract

Sektor properti dan konstruksi memainkan peran penting dalam mendukung pertumbuhan ekonomi, khususnya melalui pembangunan infrastruktur dan ekspansi investasi. Kinerja keuangan perusahaan yang beroperasi di sektor ini oleh karena itu merupakan faktor penting yang menentukan kemampuan mereka dalam mempertahankan profitabilitas dan keberlanjutan jangka panjang. Penelitian ini bertujuan untuk menguji pengaruh kinerja keuangan terhadap profitabilitas perusahaan sektor properti dan konstruksi yang terdaftar di Bursa Efek Indonesia (IDX) selama periode 2017–2019. Kinerja keuangan diukur menggunakan tiga rasio keuangan, yaitu Current Ratio (CR), Total Asset Turnover (TATO), dan Debt to Equity Ratio (DER), sedangkan profitabilitas diukur menggunakan Return on Assets (ROA). Penelitian ini menggunakan pendekatan kuantitatif dengan analisis regresi data panel berdasarkan data sekunder yang diperoleh dari laporan keuangan perusahaan yang terdaftar di IDX. Hasil penelitian menunjukkan bahwa Current Ratio tidak memiliki pengaruh yang signifikan terhadap Return on Assets, yang menunjukkan bahwa kondisi likuiditas tidak secara langsung menentukan profitabilitas pada sektor properti dan konstruksi. Sebaliknya, Total Asset Turnover memiliki pengaruh positif dan signifikan terhadap profitabilitas, yang menunjukkan bahwa efisiensi pemanfaatan aset memainkan peran penting dalam meningkatkan kinerja perusahaan. Sementara itu, Debt to Equity Ratio memiliki pengaruh negatif dan signifikan terhadap profitabilitas, yang menunjukkan bahwa tingkat leverage yang lebih tinggi dapat menurunkan laba perusahaan akibat meningkatnya kewajiban keuangan. Selain itu, hasil uji simultan menunjukkan bahwa Current Ratio, Total Asset Turnover, dan Debt to Equity Ratio secara bersama-sama mempengaruhi profitabilitas perusahaan. Temuan ini menekankan pentingnya pengelolaan aset yang efektif dan struktur modal yang optimal dalam meningkatkan kinerja keuangan perusahaan di sektor properti dan konstruksi.

Abstract

This study aims to develop and evaluate an interactive Microeconomics textbook based on Project-Based Learning (PjBL) to support students’ higher-order thinking skills (HOTS) and learning outcomes. The study employed a Research and Development (R&D) approach using the ADDIE model and involved 35 undergraduate students enrolled in the Economics Education program at Universitas Musamus. Data were collected through expert validation, lecturer and student response questionnaires, and pretest and posttest assessments. The data were analyzed using descriptive statistics, the Shapiro–Wilk test, paired-samples t-test, and N-gain analysis. The needs analysis indicated that the existing learning outcomes were predominantly focused on lower-order cognitive levels, with 66.7% at C2, 16.7% at C3, and 16.7% at C4, while C5 and C6 were not explicitly addressed. Expert validation yielded an overall score of 93.1%, while student and lecturer responses reached 92.9% and 94.3%, respectively, indicating high levels of validity and practicality. The paired-samples t-test revealed a statistically significant difference between the pretest and posttest scores, t(34) = −16.77, p < .001, with a mean N-gain score of 0.57, categorized as moderate. These findings indicate that the developed textbook is valid and practical and has the potential to support improved learning outcomes and HOTS-oriented Microeconomics learning. However, the use of a one-group pretest–posttest design without a control group limits the extent to which improvements can be causally attributed to the developed textbook.
