Abstract

Liquid fuels from polypropylene plastic waste have been successfully performed by catalytic cracking method. The catalyst used is Al-MCM-41- Ceramics. The catalyst was characterized by XRD, SEM, Pyridine-FTIR, N2-Adsorption-Desorption, and the product of catalytic cracking were investigated by gas chromatography-mass spectroscopy (GC-MS). The catalyst was using three times at sample notify A,B and C. The results showed liquid fuels have the largest percentage of gasoline (C8-C12) are 92.76; 91.92 and 90.58 percent fraction produced. The performance of catalyst showed that reuseability number were decrease, but the charactersitic of liquid fuel produced were also be agreeable to commercial gasoline standard. Keywords: olypropylene waste plastics, liquid fuels, catalytic conversion, Al-MCM-41-Cer catalyst, reuseability number.

Abstract

Perkembangan teknologi dalam industri perbankan berkembang dengan pesat. Setiap bank menyediakan sistem yang lebih baik dengan mengedepankan efisiensi dan efektifitas bagi nasabah, yaitu salah satunya dengan menyediakan layanan mobile banking (m-banking). Banyaknya jumlah mahasiswa Generasi Z di Indonesia menjadi peluang bagi setiap bank untuk memperkenalkan mobile banking yang dapat menggiring mereka untuk menggunakannya. Penelitian ini bertujuan untuk menganalisa faktor yang mempengaruhi penggunaan mobile banking pada mahasiswa di Bali dengan pendekatan Theory Acceptance Model (TAM). Metode penelitian ini bersifat kuantitatif, pengumpulan data dilakukan dengan menyebarkan kuisioner secara online kepada 100 responden yaitu mahasiswa di Bali. Data yang diperoleh kemudian diolah menggunakan Python. Hasil dari penelitian ini yaitu faktor Compatibility with Lifestyle dan faktor Social Influence memiliki pengaruh signifikan terhadap Intention to Use mobile banking pada mahasiswa di Bali. Sementara Perceive Usefulness, Perceived Ease of Use, Trust tidak menunjukkan pengaruh yang signifikan terhadap Intention to Use mobile banking pada mahasiswa di Bali. Dengan Hasil ini maka memberikan implikasi yang sangat penting bagi perbankan dalam merancang layanan mobile banking.

Abstract

The rapid growth of the Indonesian coffee industry has intensified competition among local coffee shop MSMEs, particularly in tourism destinations such as Gianyar, Bali. In this context, understanding how consumers evaluate product quality and price through perceived value is essential for sustaining competitiveness. This study investigates the direct effects of product quality and price on purchasing decisions and examines the mediating role of perceived value among consumers of Pandang Kopi, a local MSME coffee shop. A quantitative approach was employed using Partial Least Squares–Structural Equation Modelling (PLS-SEM). Data were collected from 106 consumers through accidental sampling and analyzed using SmartPLS 4.1.1.2. The results show that product quality (β = 0,159; p < 0,05) and price (β = 0,161; p < 0,05) have positive and significant direct effects on purchasing decisions. Perceived value demonstrates the strongest influence on purchasing decisions (β = 0,683; p < 0,001), explaining a substantial proportion of variance (R² = 0,79). Product quality (β = 0,309; p < 0,001) and price (β = 0,590; p < 0,001) also significantly enhance perceived value. Mediation analysis reveals that perceived value significantly mediates the relationship between product quality and purchasing decisions (β = 0,211; p < 0,001) as well as between price and purchasing decisions (β = 0,403; p < 0,001). Notably, the indirect effect of price through perceived value is stronger than its direct effect, indicating that consumers emphasize overall value rather than price alone. Theoretically, this study contributes to value-based consumer decision models by empirically validating perceived value as a central psychological mechanism in MSME coffee shops located in tourism regions. Practically, the findings suggest that local coffee shop MSMEs should prioritize sensory product quality, fair pricing, and holistic consumption experiences to strengthen perceived value and encourage purchasing decisions.
