Abstract

Empon-Empon and Wedang Pokak are traditional Indonesian herbal drinks prepared from various spices through a simple production process. Empon-Empon consists of red ginger, turmeric, nutmeg, aromatic ginger, bay leaves, lemongrass, galangal, cinnamon, and cloves. At the same time, Wedang Pokak contains red ginger, cloves, lemongrass, cinnamon, cardamom, pandan leaves, and star anise. Both drinks are widely recognized as sources of antioxidants and vitamin C, and are believed to strengthen the immune system. This study aimed to determine the vitamin C content and antioxidant activity of Empon-Empon and Wedang Pokak. Vitamin C analysis was carried out using UV-Vis spectrophotometry, which showed a maximum wavelength at 245 nm with a linear regression equation y = 0.0434x – 0.0967 (R² = 0.9942). The vitamin C content was 23.33 µg/mL (0.233%) in Empon-Empon and 20.28 µg/mL (0.202%) in Wedang Pokak. Antioxidant activity was determined using the DPPH method, yielding inhibition percentages of 21.28% (20 µg/mL), 40.16% (40 µg/mL), 46.48% (60 µg/mL), and 59.67% (80 µg/mL) for Wedang Pokak, with an IC₅₀ value of 63.33 µg/mL. This activity was lower than Empon-Empon (IC₅₀ 40.53 µg/mL) and pure vitamin C (IC₅₀ 3.77 µg/mL). In conclusion, Empon-Empon exhibited higher vitamin C content and stronger antioxidant activity than Wedang Pokak, highlighting its potential as a functional drink to support health.

Abstract

The halal food study is one of the prominent research fields in halal trends. Currently, the halal food concept is not only the worship of Muslims to Allah, but also this concept is adopted by non-Muslim with healthy lifestyle considerations. Therefore, the insight of the influenced variable on purchased intention behavior of students is crucial to research as basic information for all stakeholders, such as the seller, marketer, policymaker, government, and researchers. This study aims to identify and compare the independent variables that influence the behavior of students' purchase intentions from the school's clustering perspective. A quantitative approach has investigated the influence of attitude and need for cognition (NFC) variables on students' purchase intention behavior on halal food. The self-administrated questionnaire was used to collect the data from 561 respondents and input them into the Survey123 software. The data were analyzed using descriptive and interferential statistics. The result showed that attitude toward halal (HA) and NFC were accepted as the influenced variable on halal food purchase intention behavior. Furthermore, the students from Islamic schools tend to have purchase intentions on halal than in senior high The result of this study could be strategic marketing in the halal food industry. Then, the school must strengthen halal awareness in the syllabus.
