Abstract

Background: Moringa leaf extract is promising to develop into nutraceutical products, especially a chewable gummy. The desirable characteristics of chewable gummies are soft, elastic, springy and flexible. Gelatin is a widely used gelling agent which has been proven to maintain gel structure during storage. The other ingredients which also determine the chewable gel structure are fillers and plasticizers. The aim of this study was to determine the effect of sucrose and propylene glycol concentrations on Moringa leaf extract based on chewable gummy. Method: The preparation of chewable gummy tablets was carried out by the pour method. Factorial design study (22) was applied in this study to analyze the effect of two factors here in filler and plasticizer. Two levels of concentration were optimized in each factor, herein sucrose (30% and 35% concentration) and propylene glycol (2% and 4% concentration) on the physical characteristics of the gummy tablet. Result: The results of the factorial analysis showed that the increase in sucrose concentration will produce a longer dispersion time and lower swelling ratio. Meanwhile, the increase in propylene glycol decreases the syneresis potency. The alteration of physical characteristics was observed during 14 days of storage, particularly in dispersion time, swelling ratio, and syneresis percentage. Conclusion: Based on the results of a feasible design space, sucrose concentration (30-35%) and propylene glycol concentration (2-4%) were optimized in this study to produce the desirable characteristics of chewable gummy.

Abstract

Background: This research aims to find the best mixture of kombucha that can accept by the community in BTN Pa’jukukang, Bantaeng district. Kombucha is a fermented beverage made from tea and sugar mixed with the kombucha culture. A kombucha culture is a mixture of bacteria and yeast designated as SCOBY in this work. Methods: In this research, kombucha was made from 4 various teas, i.e., black tea, green tea, oolong tea, and white tea.  Each tea was fermented for 7 and 14 days. The kombucha tea samples were subjected to an organoleptic test based on the consumer's acceptance level. The organoleptic test data were analyzed using the hedonic and score test. Results: The test result showed that respondents preferred to choose the color, the smell, and the taste of the black kombucha tea which was fermented for 7 days. Conclusions: Furthermore, the observation of the physical characteristics of the tea showed that the longer the fermentation time, the more acidic the kombucha. This acidic kombucha resulted from the decreasing sugar level during the fermentation process due to the activity of bacteria and khamir in the SCOBY.

Abstract

Background: Biology education has a vital role in scientific development, strengthening the position of biology education for sustainable development and advancing biological science. During this time, biology materials developed rapidly. Methods: Writing the word Abstract using Cambria 9pt, in italics. The Abstract consists of 150-250 words written in one paragraph, containing the essence of the manuscript, background, research objectives, methods, results, and conclusions. Results: Biology education material that has developed since there were three changes to the curriculum in Indonesia after the issuance of Law Number 20 of 2003 concerning the National Education System does not appear to have shown any significant changes specifically in the subject matter for class X SMA. Curriculum policies and the development of textbooks in Indonesia focus more on and continue the material in the previous curriculum since the emergence of the competency-based curriculum (2004). Conclusions: The development of biology education in Indonesia from materials, textbooks, and curriculum policies does not show a significant change and development in the development of biology science for class X SMA. This study concludes that textbooks and curriculum policies have not been able to change the perspective and substance of the direction of learning biology in Indonesia. So the portrait of the capacity and insight of the Indonesian generation's knowledge about biology can be seen from the curriculum policies and the existing materials.

Abstract

Background: Microspores are small haploid spores that develop into the male gametophyte. Microsporocytes undergo meiotic division to form microspores. Microspores can be found in seedless and seed plants. The microspores in each flowering plant are different. This study aims to observe microspores on eggplant flowers. Method: Microspore observations were carried out on different flower bud sizes until the flower buds bloomed. Result: The results showed microspores in eggplant had different stages of development for each flower bud size. The stages of microspore development observed were Early uninucleate (Young microspore), Mid-uninucleate, Late uninucleate (Vacuolate microspore), early binucleate (Young bicellular pollen), mid-binucleate, and mature pollen. Conclusion: In eggplant microspore culture, anther length is a strong parameter to predict the stage of microspore development contained there in.

Abstract

Background: Cambodian trees are known to be resistant to biotic and abiotic stresses which may be influenced by the presence of rhizosphere bacteria as Plant Growth-Promoting Rhizobacteria (PGPR). This study aims to isolate and characterize Cambodian tree rhizosphere bacteria from burial soils that have the potential to produce IAA. Methods: Rhizospheric soil samples were taken from Pracimaloyo TPU, Surakarta, Central Java, at 5 points attached to the surface of the frangipani tree roots to be inoculated using the scattering cup method at 10-5 and 10-6 dilutions in NA (nutrient agar). After 48 hours, colonies were counted to obtain population data. The ability of rhizosphere bacteria to produce IAA was carried out qualitatively and quantitatively at the age of 24 and 48 hours of culture. Rhizospheric bacteria isolates potential to produce IAA were characterized macroscopically (colony morphology) and microscopically by Gram staining. Results: The population of frangipani tree rhizosphere bacteria in all blocks did not show a significant difference and was detected to have a population between 1.9 – 10.4 x 106. Qualitative test of the ability to produce IAA, it was detected that 34.88% of isolates produced very high IAA. The highest concentration of IAA was produced by isolate P37, followed by P38 and P24 at 48 hours of age, namely 113.58 ppm, 77.95 ppm, and 55.69 ppm. All potential isolates to produce IAA are cocci-shaped gram-negative bacteria. Conclusion: The population of frangipani tree rhizosphere bacteria in Pracimaloyo TPU ranged from 1.9-10.4 x 106 CFU/g and 34.88% had the ability to produce IAA. The concentration of IAA produced was higher at 48 hours of culture compared to 24 hours with the highest concentration by isolate P37 (83.098 ppm and increased to 113.588 ppm). Isolate P37 is a gram-negative cocci-shaped bacterium and irregular colonies.
