Abstract

This research aims to analyze the impact of inflation on the purchasing power of the community. This study uses a qualitative approach through interviews and literature studies as secondary data. The results conclude that inflation has a proven negative effect on the purchasing power of the community, especially low-income groups and small business actors. At a broader level, high and uncontrolled inflation can widen social disparities and reduce welfare, as the poor bear a heavier burden than high-income groups. Overall, these findings emphasize that inflation control must be accompanied by policies to protect purchasing power so that economic stability goes hand-in-hand with social justice and welfare.

Abstract

Penelitian ini dirancang untuk meneliti pengaruh sertifikasi halal, kualitas pelayanan, dan kepercayaan konsumen terhadap kinerja usaha ultra mikro, khususnya dalam hal peningkatan penjualan. Data dikumpulkan lewat metode kuantitatif dengan mendistribusikan kuesioner kepada pelanggan di area Kota Medan serta Kabupaten Deli Serdang. Pengolahan data memanfaatkan Partial Least Squares–Structural Equation Modeling (PLS-SEM) untuk memverifikasi validitas, reliabilitas, dan interkoneksi antar variabel. Temuan studi mengungkap bahwa sertifikasi halal, kualitas layanan, serta kepercayaan konsumen semuanya memberikan kontribusi positif dan bermakna terhadap kinerja usaha ultra mikro dalam mendongkrak omzet. Kualitas layanan muncul sebagai faktor paling berpengaruh di antara ketiganya. Nilai R-square yang tinggi mengindikasikan model penelitian ini kuat dalam memprediksi fluktuasi kinerja usaha. Secara esensial, sertifikasi halal mempertajam keunggulan kompetitif, layanan prima membangun kepuasan serta kesetiaan pelanggan, sedangkan kepercayaan konsumen menjaga ikatan jangka panjang yang mendukung performa bisnis. Secara aplikatif, pemilik usaha ultra mikro dianjurkan untuk menyatukan upaya peningkatan kualitas pelayanan, penguatan sertifikasi halal, dan pengembangan kepercayaan pelanggan guna mengoptimalkan kinerja serta daya tahan usaha di tengah kompetisi pasar yang semakin sengit.

Abstract

This study aims to compare the investment performance of sharia stocks and ANTAM gold based on return and risk levels during the 2023–2025 period. The methodology used is a quantitative approach with a descriptive-comparative research model. The research data consists of the weekly closing prices of sharia stocks included in the Indonesia Sharia Stock Index, namely AALI, ACES, and ABMM, as well as the price of ANTAM gold. Data processing was conducted by calculating returns and risk using standard deviation, followed by the Jarque–Bera normality test, the Augmented Dickey–Fuller (ADF) stationarity test, the independent samples t-test, and volatility analysis using the GARCH (1,1) model. The results of the study indicate that there is no significant difference in return levels between sharia stocks and ANTAM gold. However, sharia stocks have higher risk and volatility levels compared to gold. These findings indicate that gold tends to be more stable as a hedging instrument, while sharia stocks offer greater return potential with the consequence of higher risk. The results of this study recommend portfolio diversification between sharia stocks and gold, and can serve as a reference for regulators. Further research is suggested to expand the study period and variables.
