Abstract

Increasingly intense business competition requires entrepreneurs to thoroughly understand the factors that drive consumers to make purchasing decisions. This study aimed to determine the extent to which distribution channels, product availability, and price influence consumer purchasing decisions at the Apong Cricket Farming Business in Tebing Tinggi City. A total of 96 respondents were involved in this research through an incidental sampling technique, with data collected via questionnaires and analyzed using multiple linear regression on SPSS version 25.In terms of individual influence, distribution channels and price proved to be significant, with significance values of 0.002 and 0.000, respectively, whereas product availability did not show a significant effect, with a value of 0.378. When tested simultaneously, the three variables collectively proved to significantly influence purchasing decisions, yielding a calculated F-value of 26.277 and a significance level of 0.000. Furthermore, the Adjusted R Square value of 0.444 implies that 44.4% of the variance in purchasing decisions can be explained by the three variables in this model. These results indicate that price stability and distribution effectiveness are the two main factors that micro-agribusiness entrepreneurs must consider when designing well-targeted marketing strategies.

Abstract

This research investigates how human capital, professional development, institutional conditions, lecturer performance, and perceived educational quality are connected in private higher education institutions in North Sumatra, Indonesia. The study applied an explanatory quantitative approach and used questionnaire responses from 247 lecturers. The proposed direct and mediating relationships were examined with Partial Least Squares Structural Equation Modeling (PLS-SEM). Several limitations should be acknowledged, particularly the cross-sectional nature of the design and the use of lecturer self-reports to assess educational quality, both of which may create common-method bias. The findings are also tied to the setting of private universities in North Sumatra, so their applicability to other institutional contexts should be interpreted carefully. The analysis demonstrates that human capital, professional development, and institutional factors contribute significantly to lecturer performance, with human capital producing the largest effect. Lecturer performance is strongly associated with perceived educational quality (beta = 0.76). The mediation test further shows that lecturer performance partially explains the pathway from human capital to perceived educational quality. Overall, the study offers localized empirical evidence on the role of lecturer performance as an important channel through which lecturer competencies and institutional support are linked to quality perceptions in private higher education.

Abstract

Emas merupakan aset lindung nilai (save haven) yang banyak digunakan investor untuk meengurangi risiko ketidakpastian ekonomi dan geopolitik. Namun,pergerakan harga emas yang cenderung volatile dan tidak stabil menyebabkan proses peramalannya menjadi kompleks. Penelitian ini bertujuan untuk menganalisis kemampuan model hibrida ARIMA-GARCH dalam meramalkan harga emas selama periode ketidakpastian global. Data yang digunakan berupa harga penutupan emas harian (XAU/USD) dari Januari 2020 hingga Maret 2025. Hasil penelitian menunjukkan bahwa model ARIMA (2,1,22) memiliki nilai Akaike Information Criterion (AIC) terendah, tetapi tidak memenuhi asumsi stasioneritas karena nilai modulus autogressive yang tidak stabil. Pengujian lebih lanjut menunjukkan adanya efek ARCH pada residual, sehingga diperlukan permodelan GARCH. Model GARCH (0,1,2) dengan komponen rata-rata MA(2) dipilih sebagai model terbaik karena mampu mengatasi heteroskedastisitas yang ditunjukkan oleh hasil uji ARCH dengan nilai probabilitas lebih besar dari 0,05. Evaluasi kinerja model menghasilkan nilai Mean Absolute Percentage Error (MAPE) sebesar 18,37%, yang menunjukkan tingkat akurasi peramalan yang baik. Hasil penelitian mengindikasikan bahwa model ARIMA-GARCH cukup efektif dalam memprediksi harga emas pada periode volatilitas tinggi dan dapat digunakan sebagai alat pendukung pengambilan keputusan investasi

Abstract

TikTok's rise as a dominant short-form video platform has created new channels through which User-Generated Content (UGC) influences consumer behavior. This study investigates the effect of TikTok UGC on purchase intention toward Es Krim Pokat Au, a heritage culinary micro-enterprise in Tebing Tinggi, North Sumatra—a context underrepresented in existing UGC literature dominated by fashion and cosmetic studies in metropolitan markets. A causal-quantitative design was adopted, with data collected from 96 purposively selected TikTok users who had been exposed to UGC content about this product. Instruments were validated using Pearson Product Moment (r table = 0.355; all items valid) and shown to be reliable (Cronbach's Alpha: X = 0.818, Y = 0.791). Residuals were normally distributed (Monte Carlo Sig. = 0.427 > 0.05). Simple linear regression via IBM SPSS 25 revealed a significant positive effect of UGC on purchase intention (β = 0.693; t = 9.380; p = 0.000 < 0.05; R² = 0.483). These findings confirm that authentic, visually appealing, and culturally relevant UGC serves as a cost-effective promotional mechanism for traditional culinary micro-enterprises targeting digital-native consumers.
