Abstract

This study aims to determine the effect of fruit pruning and application of Potassium on the growth and production of strawberry plants (Fragaria chiolensis). This study used a randomized block design (RBD) with 2 factors. The first factor was fruit pruning consisting of 4 levels: P0 = No pruning, P1 = 1 pruning, P2 = 2 pruning, P3 = 3 pruning. The second factor is Potassium fertilizer consisting of 4 levels: K0 = 0 g/plant, K1 = 2 g/plant, K2 = 4 g/plant, K3 = 6 g/plant. The observed variables were plant height (cm), flowering age (days), Fruit Weight (g), Fruit Volume (cm3), Sugar Content (%), Plant Wet Weight (g), and Plant Dry Weight (g). The results showed that pruning three fruits/plant increased plant height, fruit weight, fruit volume, sugar content, fresh weight and dry weight. Applying potassium fertilizer up to a dose of 6 g/plant can increase plant height, flowering time, fruit weight, fruit volume, sugar content, and wet and dry weight. Meanwhile, the interaction between fruit pruning and potassium application had no significant effect on all observed parameters.

Abstract

Various compounds and extracts obtained from a wide variety of plants can be employed as natural antioxidants in cosmetics applications. Patchouli oil (Pogostemon cablin Benth.) and drumstick oil (Moringa oleifera) have the ability to fight free radicals and keep skin hydrated, making them excellent candidates for usage as an active component in cosmetic goods like body cream. This research aims to determine the physical quality of a body cream formulation by subjecting it to an accelerated stability test technique for seven cycles. The preparation was evaluated in each cycle, and the results were analyzed using student's t-test. The evaluation results of body cream preparation showed that there was no significant difference (p>0.05) in the preparation during each cycle. As a result, the formulation of the body cream remained stable throughout the storage term of at least six months, which indicates that it can be utilized for an entire year when kept at room temperature. After two weeks of application on dry skin, it was demonstrated that the formulation had the capacity to increase the amount of moisture contained in the skin (from 30% to 60%). In conclusion, the formulation is potentially produced as commercial cosmetic product in the future.

Abstract

Teachers should have different knowledge types including technological, pedagogical, and content to realize effective learning in the digital era. Technological Pedagogical and Content Knowledge (TPCK) is a framework that explains these knowledge types and the interactions between them. It is considered to enable chemistry teachers’ multifaceted teaching. Coping, for this reason, a study to examine chemistry teachers’ level of TPCK is needed. This paper reports the level of chemistry teacher’s TPCK and their perception in terms of teaching stage, gender, and age. The study involved fifty-three students of chemistry education in a public university in Indonesia. A quantitative method was applied to explore their perspective on TPCK. Data were collected through surveys and interviews. The findings showed that the majority of chemistry teachers’ TPCK skills are currently good. They integrate technology into their teaching while conducting online learning due to the COVID-19 pandemic. In terms of teaching stage, age, and gender, provide deep insight into seven indicators of TPCK. However, some indicators still need to be improved, so a TPCK training program for individuals or centralized individuals should be added to the chemistry department program.
