Abstract

VCO (Virgin Coconut Oil) adalah hasil olahan minyak kelapa yang diproses dari ekstraksi daging buah kelapa segar tanpa melibatkan reaksi kimia atau pemanasan ekstrem. Tujuan dari penelitian ini adalah untuk mengkaji efek dari penambahan Enzim Zingibain yang berasal dari Rimpang jahe terhadap kualitas VCO, dengan fokus pada analisis parameter mutu seperti kadar asam lemak, asam lemak bebas (ALB) dan kadar air. Proses fermentasi dilaksankan dengan variasi jumlah enzim yang digunakan (0, 8 ml, 12 ml, dan 16 ml) dan waktu fermentasi (24, 36, 48 dan 60 jam). Berdasarkan hasil penelitian, dikethaui bahwa pada VCO tanpa enzim dan fermentasi selama 24 jam, asam lemak utama yang teridentifikasi adalah Decanoic acid methyl ester, Lauric acid, Myristic acid, dan Hexadecanoic acid. Sementara itu, VCO dengan enzim 8 ml dan fermentasi 48 jam mengandung senyawa tambahan seperti Octanoic acid ethyl ester, Zingiberene, Dodecanoic acid methyl ester, dan beberapa ester asam lemak lainnya. Untuk analisa bilangan asam lemak bebas menunjukan nilai rata-rata 0,1% hingga 0,2%, baik pada VCO tanpa enzim maupun dengan penambahan enzim zingibain. Pada hasil analisa kadar air pada VCO yang diolah secara enzimatis menunjukan hasil yang sangat rendah dengan kadar air sebesar 0,002% dan kadar air tertinggi sebesar 0,01%. Berdasarkan hasil penelitian disimpulkan bahwa seluruh sampel VCO memenuhi standar minyak kelapa sesuai SNI 7382-2008 asam lemak bebas tidak melewati 0,2% dan kadar air tidak lebih dari 0,2%.

Abstract

The rapid expansion of digital payment systems has become a central element of monetary and financial sector reforms in emerging economies. In Indonesia, the implementation of the Quick Response Code Indonesian Standard (QRIS) aims to enhance payment system efficiency, interoperability, and financial inclusion. However, the effectiveness of such reforms depends not only on infrastructure availability but also on public awareness and information-seeking behaviour, which typically precede actual adoption and sustained usage. This study examines whether online search intensity can serve as a high-frequency indicator of public attention toward digital payment infrastructure in Indonesia. Using monthly Google Trends data from January 2023 to December 2025, the analysis focuses on search interest in “QRIS” as the primary variable, with “Layanan Online” and “Smart City” included as contextual benchmarks representing broader digitalisation narratives. A time-series–oriented approach is employed, incorporating stationarity testing, first differencing, and correlation as well as lead–lag analysis to examine the dynamics of public attention. The findings indicate that changes in public attention to QRIS display distinct temporal patterns and exhibit meaningful dynamic relationships with attention to online services, suggesting that shifts in attention to digital payments may precede broader engagement with digital public services. These results support the interpretation of search-based indicators as early signals of behavioural readiness for digital payment adoption. From a policy perspective, the study highlights the usefulness of high-frequency attention data for monitoring payment system reforms and informing communication strategies to support digital financial inclusion Keywords: Digital payments; QRIS; Financial inclusion; Google Trends; Public attention
