Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kualitas produk, persepsi harga, dan citra merek terhadap keputusan pembelian minuman Yakult di Kota Palangka Raya. Jenis penelitian yang digunakan adalah penelitian kuantitatif dengan metode survei. Data dikumpulkan melalui kuesioner yang disebarkan kepada 100 responden yang pernah mengonsumsi Yakult di wilayah Palangka Raya. Teknik analisis data yang digunakan adalah analisis regresi linear berganda. Hasil penelitian menunjukkan bahwa secara parsial maupun simultan, kualitas produk, persepsi harga, dan citra merek berpengaruh positif dan signifikan terhadap keputusan pembelian Yakult. Temuan ini mengindikasikan bahwa konsumen di Palangka Raya sangat mempertimbangkan ketiga variabel tersebut sebelum memutuskan untuk membeli Yakult. Oleh karena itu, perusahaan disarankan untuk terus menjaga dan meningkatkan kualitas produk, memberikan harga yang kompetitif, serta memperkuat citra merek melalui strategi pemasaran yang efektif.

Abstract

ABSTRACT. Heavy metal pollution is a significant environmental issue with detrimental effects on ecosystem and human health. Therefore, comprehensive handling need to be carried out. Herein we studied initial screening adsorption of heavy metals including Ni, Cu, Zn, Cd, and Pb using Metal-Organic Frameworks class of Materials Institute Lavoisier (MIL) based on Cr(III). MIL-101(Cr), and its modification with ethylenediamine (EA), and MIL-101(Cr)-NH2 were prepared under hydrothermal condition. X-ray diffraction and FT-IR analysis confirmed the formation of the targeted materials. A new absorption band at 1050 cm-1 corresponds to vibration of C-N which indicates the successful EA modification into MIL-101(Cr). Nitrogen sorption isotherm measurement revealed MIL-101(Cr) and EA@MIL-101(Cr) have a specific surface area of 2548.6 and 2079 m²/g with micropore-sized, while MIL-101(Cr)-NH2 has a specific surface area of 1583.4 m²/g with micro and mesopore-sized. Adsorption performance was assessed through batch experiments monitored by atomic absorption spectroscopy. The results show that MIL-101(Cr) and its modification with EA exhibit higher adsorption capacities on cadmium and nickel metal ions, compared to MIL-101(Cr)-NH2. Meanwhile, MIL-101(Cr)-NH2 and MIL-101(Cr) show more dominant adsorption capabilities on zinc and copper ions compared to the EA-modified MIL-101(Cr). This result suggests that the material's porosity still plays a dominant role in the adsorption processes compared to amine functionalize group on MIL itself.

Abstract

This study aims to analyze the influence of social media and price perception on consumer purchase intention with brand image as a mediating variable at UMKM Kampung Lauk Palangka Raya. The research method employed a quantitative approach using Partial Least Square-Structural Equation Modeling (PLS-SEM) analysis on 97 respondents who are consumers of UMKM Kampung Lauk. The results show that social media has no significant effect on brand image (t-statistic 0.420, p-value 0.675), but has a significant negative effect on consumer purchase intention (t-statistic 2.447, p-value 0.014). Price perception has a very strong positive effect on brand image (t-statistic 11.313, p-value 0.000) with a path coefficient of 0.801, but does not directly affect consumer purchase intention (t-statistic 0.105, p-value 0.917). Brand image significantly and positively influences consumer purchase intention (t-statistic 3.339, p-value 0.001) with a path coefficient of 0.489. Mediation testing indicates that brand image does not mediate the influence of social media on purchase intention (Direct-only nonmediation), but fully mediates the influence of price perception on consumer purchase intention (Indirect-only mediation) with a coefficient of 0.392. This study concludes that brand image is a highly dominant key factor in increasing consumer purchase intention, and positive price perception must first establish a good brand image before it can drive purchase intention. UMKM Kampung Lauk needs to optimize its social media strategy and maintain price consistency with product quality to strengthen brand image and increase consumer purchase intention.
