Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi niat dan perilaku konsumen dalam menggunakan layanan e-wallet dengan menggunakan model penerimaan UTAUT. Model penerimaan UTAUT dianalisis menggunakan Structural Equation Model (SEM). Pengambilan data dilakukan dengan menyebarkan kuisioner secara online. Hasil analisis menunjukkan Faktor-faktor yang memengaruhi niat penggunaan layanan e-wallet oleh konsumen adalah performance expectancy (PE), effort expectancy (EE), dan social influence (SI). Faktor yang memengaruhi perilaku konsumen dalam mengadopsi layanan e-wallet adalah facilitating condition (FC), dan behavioral intention (BI).

The increasing adoption of e-wallet services can be influenced by the high number of productive age population and the increasing number of cellular and internet subscribers. This study aims to determine the factors that influence consumer intentions and behavior in using e-wallet services using the UTAUT acceptance model. UTAUT acceptance model was analyzed using Structural Equation Model (SEM). Data collection was done by distributing online questionnaires. The analysis results showed that the factors that influence the intention to use e-wallet services by consumers are performance expectancy (PE), effort expectancy (EE), and social influence (SI). Factors that influence consumer behavior in adopting e-wallet services are facilitating conditions (FC), and behavioral intention (BI). Age consumers have differences in the perception of facilitating conditions on the intention and behavior of using e-wallet services.

Judul: Determinants of the Decision to Use LinkAja Sharia Services in Millennial Muslim Communities
Abstrak: Indonesia memiliki potensi besar dalam perkembangan industri keuangan syariah dunia, namun pangsa pasar e-wallet syariah masih lebih rendah dibandingkan dengan pangsa pasar e-wallet konvensional. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan penggunaan Layanan Syariah LinkAja pada masyarakat Muslim generasi milenial. Metode analisis yang digunakan dalam penelitian ini adalah PLS-SEM yang dilakukan dengan menggabungkan analisis faktor dan analisis regresi dengan tujuan menguji hubungan antar variabel pada sebuah model. Hasil penelitian menunjukkan bahwa perceived ease of use (PEOU) berpengaruh positif terhadap perceived usefulness (PU). PEOU dan PU berpengaruh positif terhadap attitude. Tetapi, religiosity tidak berpengaruh terhadap attitude. Adapun PU, attitude, perceived behavioral control, dan subjective norm berpengaruh positif terhadap intention to use. Intention to use berpengaruh positif terhadap actual usage., Indonesia has great potential in the development of the world's halal industry, but the share of the sharia e-wallet market is still lower than the market share of convention e-wallets.This study is conducted to analyze the factors influencing the use of LinkAja Sharia Services on Muslim millennials. The analytical method used in this study is PLS-SEM which is carried out by combining factor analysis and regression analysis with the aim of examining the relationship between variables in a model. The results showed that perceived ease of use (PEOU) has a positive effect on perceived usefulness (PU). PEOU and PU have a positive effect on attitude. However, religiosity has no effect on attitude. PU, attitude, perceived behavioral control, and subjective norms have a positive effect on intention to use and intention to use has a positive effect on actual usage.

Judul: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
