Abstract

Utilization of waste cooking oil as a raw material for biodiesel production is an effective solution to reduce environmental pollution and produce renewable energy. The high free fatty acid content in waste cooking oil is a major problem in the industry, so it requires an effective catalyst in the biodiesel production process. Zn terephthalate MOF has a large surface area, porous structure, and good thermal stability, making it very effective as a heterogeneous catalyst for the biodiesel esterification process. This study aims to synthesize and characterize Zn terephthalate MOF using a hydrothermal method with a Teflon autoclave, and evaluate its effectiveness as a catalyst. The analysis was carried out by testing the acidity of the Zn terephthalate MOF catalyst characterized by XRD, TGA, PSA, and the ability to convert waste cooking oil into biodiesel. The results showed that the obtained MOF-5 had an acidity of 4.33 mmol/g, the XRD results showed a 2 theta angle and the catalyst intensity was the same as JCPDS no. 96-432-6738. TGA results showed that the Zn terephthalate catalyst had thermal stability up to 300OC, and PSA results showed particles distributed at 8428.62 nm. This proves that the Zn terephthalate MOF catalyst can reduce the FFA value of waste cooking oil and convert it into biodiesel with a conversion rate of 94.18%, and the catalyst can be reused up to five times with relatively stable performance

Abstract

The high level of competition among retail MSMEs in selling contemporary beverages necessitates innovation and creativity among business owners in developing their sales strategies. The purpose of this study was to determine the influence of green business practices, packaging quality, and price on consumer purchasing interest of Mixue MSMEs in Bogor Regency. This study used a quantitative method with an associative approach, a type of research that aims to explain systematically, factually, and precisely the facts and characteristics of a particular object or population. The sampling technique in this study was non-probability sampling with a purposive sampling technique, which is a sampling technique based on specific considerations. The participating respondents were 45 people with the criteria of having purchased Mixue products more than 4 times, being at least 17 years old, following the @mixueindonesia Instagram account, and residing in Bogor Regency. The test tools used included data quality testing, classical assumption testing, influence testing, and hypothesis testing using SPSS 26 software. The test results show that the green business and quality variables partially influence the purchasing interest of Mixue MSME consumers in Bogor Regency. However, there is no reason to state that the price variable influences the repurchase interest of Mixue MSME consumers. The results also show that the green business, packaging quality, and price variables simultaneously influence the purchasing interest of Mixue MSME consumers in Bogor Regency.
