Abstract

Polyphenol, which is very beneficial to the human body, especially as an obesity inhibitor, is one of the leading nutrient content in green tea leaves. To increase popularity as well as practicability, product development needs to be conducted, one of which is to produce an effervescent instant tea. However, a high-density instant tea powder is required in this product development. This study was conducted to predict the significant process variables which affect the density as well as the yield of the instant tea powder. The exploration of significant process variables was conducted based on the Design of the Experiment, while the tea extract was produced using maceration techniques. Maltodextrin was added to the tea extract based on the concentration filler variable. The instant tea powder was produced by the spray drying method, which variable includes the concentration of maltodextrin (filler), the pump flow rate (feed pump), the outlet temperature (Tout), the fan speed, and the atomization air pressure (nozzle). The tapped density of the instant tea powder was analysed and the yield was calculated for each condition. Based on the Pareto graph, it was found that the atomization air pressure (nozzle) is the most significant variable in the spray dry process of instant tea powder.

Abstract

This research discusses the critical role of phosphatase enzymes in soil, particularly in the phosphorus cycle and soil fertility. Acid and alkaline phosphatases are identified as crucial components, with their activities serving as indicators of soil fertility. This study evaluates the soil chemical and biological characteristics in mangosteen orchards in the Mangosteen Thematic Village, specifically in monoculture and polyculture cultivation patterns on slopes ranging from 8-15%. Soil pH, organic C, available P, total P, soil respiration, microbial C-biomass, and phosphatase enzyme activities were assessed at 0-20 cm and 20-40 cm depths. Total P did not show significant changes based on cultivation patterns. The results show that the soil pH values tend to be acidic to slightly acidic (5.21- 5.45) with no significant differences based on depth. Organic C, available P, soil respiration, microbial C-biomass, and acid phosphatase enzyme activity were higher in polyculture cultivation patterns but alkaline phosphatase enzyme activity was higher in monoculture. The cultivation pattern influences the dynamics of agricultural ecosystems and should be considered in land management to enhance productivity and soil ecosystem balance.

Abstract

Children are a trust that must be honored and granted their rights, particularly the right to education, with parents serving as the child's first educators. This study aims to analyze the relationship between parenting styles and students' motivation in learning the Qur’an. Using a quantitative approach with a descriptive-correlational method, the study involved 38 fifth-grade students of SD Islam Salman Al Farisi Bekasi and their parents. Purposive sampling was applied, along with validity and reliability testing of the instruments. Results showed: 1) Parenting style was classified as moderately democratic (mean = 87.84), 2) Students’ motivation in learning the Qur’an was categorized as moderate with dominant extrinsic motivation (mean = 64.76), and 3) A very strong correlation was found between parenting style and learning motivation (r = 0.825; R² = 68.1%). These findings highlight the vital role of parental involvement in fostering children's motivation to learn the Qur’an from an early age within the family environment.
