Abstract

This research aims to synthesize and characterize aluminum formate-metal organic framework (ALF-MOF) from beverage can waste using solvothermal method. The solvothermal method was chosen due to its ability to produce materials with controlled structures and superior properties. This research also uses a Central Composite Design (CCD) experimental design to optimize the synthesis conditions. The ALF-MOF synthesis process was carried out by mixing Al(OH)3 powder obtained from the extraction of aluminum in beverage can waste and HCOOH in DMF. The mixture was stirred and heated in an autoclave reactor at Al/HCOOH mole ratios (1:3, 1:5, and 1:7) and reaction times (1, 2, and 3 hours). Furthermore, the products were characterized using FTIR, XRD, SEM, and BET. Based on the results, it is known that the optimum synthesis conditions were achieved at the Al/HCOOH mole ratio and reaction time of 1:3.729 and 2.874 hours, respectively, with an ALF-MOF yield value of 87.71%. Characterization results showed the presence of COO groups and Al-O-Al groups. The ALF-MOF product also has an average particle diameter of 23.57 nm with a %crystallinity of 51.30% and a surface area of 128.507 m2/gram.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kemudahan penggunaan, kepercayaan, dan pengetahuan terhadap minat nasabah dalam menggunakan layanan e-banking Bank BPD Cabang Godean. Kemajuan teknologi informasi mendorong perbankan untuk menghadirkan layanan digital guna meningkatkan efisiensi dan kenyamanan transaksi. Namun, minat nasabah dalam memanfaatkan layanan e-banking masih rendah, terutama karena keraguan terhadap keamanan dan kompleksitas sistem. Jenis penelitian ini adalah kuantitatif. Data dikumpulkan melalui kuesioner kepada nasabah Bank BPD Cabang Godean. Teknik analisis data menggunakan regresi linier sederhana dan berganda, serta uji t dan uji F untuk mengetahui signifikansi pengaruh masing-masing variabel. Hasil penelitian menunjukkan bahwa kemudahan penggunaan, kepercayaan, dan pengetahuan berpengaruh positif dan signifikan terhadap minat menggunakan e-banking, baik secara parsial maupun simultan. Temuan ini menunjukkan pentingnya peningkatan literasi digital dan kepercayaan nasabah dalam mendorong adopsi layanan e-banking.
