Abstract

Bidara leave (Ziziphus mauritiana L.) are plants that contain bioactive compound cuch as saponins that have the potential as antioxidants. The saponin content fuctions as a natural surfactant that has the potential to be applied in the soap, cosmetics, and pharmaceutical industries. This study aims to determine the effect of microwave power and extraction time on the characteristics of bidara leaf extract and to determine the best microwave power and extraction time to produce bidara leaf extract using the Microwave Assisted Extraction method. The experimental design used was a factorial Randomized Block Design with 2 factors, namely microwave power consisting of 3 levels, namely 180, 300, and 450 watts and ectraction time also consisting of 3 levels, namely 5, 9, and 13 minutes. Data analysis was carried out using (Analysis of Variance) and if the treatment affect the observed variables, it was continued with (Duncan’s Multiple Range Test). The results showed that microwave power and extraction time significantly affected the yield, saponin content of the crude extract, foam height, and antioxidant capacity. The interaction between treatments significantly affected the saponin content of the crude extract. However, the ineraction did not significantly affect the yield, foam height, and antioxidant capacity. The best treatment to produce bidara leaf extract as a source of saponins was obtained based on the effectiveness index test with a microwave power of 450 watts and an extraction time of 13 minutes with the characteristics of a yield value of 31.38 ± 1.24%, a saponin content of the crude extract of 60.80 ± 0.57%, a foam height of 9.17 ± 0.71 mm, and an antioxidant capacity of 3.54 ± 0.23 mg GAEAC/g.

Abstract

Bioethanol is produced by the fermentation of glucose (sugar) from natural sources using microorganisms. Prior isolate IS258 was distinguished as a potential yeast to produce bioethanol. This study aimed to determine the optimum fermentation temperature and compare fermentation media using IS258 isolate as a starter to produce ethanol optimally. This study conducted four fermentation temperature treatments (24, 26, 28, and 30 °C) and compared two fermentation media, namely, PYG (Peptone Yeast Glucose) media used in the lab for probed, and coconut sap in traditional fermentation. There are diverse stages that were conducted in this research, namely cell rejuvenation, propagation of the IS258 isolate, fermentation, distillation, and calculation of tested variables. The optimum temperature of fermentation acquires at 28 °C with a difference of total dissolved solids 12,4 ⸰brix, which attains 104,13 ml of accumulated ethanol. During the comparison test of fermentation media, the optimum PYG media produced the highest total ethanol, which was 105,46 ml. The difference in the total yield of ethanol is affected by the differences in the nutrients of carbon (C) and nitrogen (N) elements contained between the media, which was lacking in coconut sap

Abstract

In the village of Blahkiuh, located in the Abiansemal sub-district, Badung regency, there are many sellers of traditional foods. One of the traditional food sellers there is Men Budi. He sells traditional chicken sate lilit. The intense business competition has led business owners to change their marketing strategies by improving product quality and analyzing consumer importance and satisfaction. This study aimed to assess the quality attributes of chicken sate lilit, importance and satisfaction levels,and develop strategies to enhance the of Men Budi's chicken sate lilit. The Quality Function Deployment (QFD) method was employed for the analysis. The findings identified eight quality attributes of chiken sate lilit that were important and satisfactory to consumers: taste, texture, size, price, packaging, cleanliness, aroma, and color. Taste received the highest consumer importance ranting (4.53), while aroma and color scored the lowest (4.18). in terms of satisfaction, aroma ranked the highest (4.31), while texture was rated the lowest (3.95). Improvement priorities included texture, price, cleanliness, color, and taste. Additionally, technical parameters requiring attention were mixing, grilling, and raw material preparation.
