[THE EFFECT OF NATURAL BOOSTERS ON THE GROWTH OF TUBERS OF Amorphophallus paeoniifolius (Dennst.) Nicolson. Amorphophallus paeoniifolius is a plant with high economic value in the food sector due to its glucomannan content of approximately 20%, which plays a role in lowering blood sugar and cholesterol levels. Its tubers are also rich in resistant starch and glucomannan fiber, offering potential for development as a postbiotic. Additionally, this plant is utilized in the food and cosmetic industries and exhibits antibacterial and antifungal properties. However, its cultivation remains limited, primarily due to a lack of information regarding its benefits and propagation techniques. This study aims to analyze the effect of natural growth boosters on the tuber growth of A. paeoniifolius in the conservation area of the Science Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu. The research employed a descriptive method using stem tuber propagation techniques with four treatments: shallot extract, bamboo shoot extract, control (no booster), and Rootone-F, each with six replications. Observed variables included stem height, stem diameter, and the number of shoots over a 10-week period (August–October 2024). The results showed that the shallot treatment yielded the highest growth rate at 66% (4 samples sprouted), followed by Rootone-F at 50% (3 samples), while the control and bamboo shoot treatments each resulted in 16.6% (1 sample). Shallot extract also demonstrated superior efficacy in stimulating the emergence of multiple shoots per tuber. The environmental conditions during the study were optimal, with temperatures of 27.8–32.3 °C, humidity levels of 56.5–77%, and soil pH ranging from 6.15 to 6.5. In conclusion, natural growth boosters, particularly shallot extract, positively influence the tuber growth of A. paeoniifoliu

Amorphophallus titanum is an endemic flora of Sumatra that was listed in the IUCN Red List in 2018 under the endangered category. Conservation efforts must be undertaken to preserve A. titanum both ex situ and in situ. Additionally, artificial propagation of plants needs to be carried out to obtain seedlings that can be replanted in their natural habitat or conservation areas. Propagation through the rachis cutting method is interesting to conduct because it is considered easier and more cost-effective compared to other methods. This research aims to determine the potential success of the planting media used and the challenges faced in the propagation of A. titanum through the rachis cutting method, conducted at the Pondok Sains Terpadu (POSTER) conservation, Science Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu. The planting media used were cocopeat and soil, with 40 samples of A. titanum rachis and 20 repetitions for each planting medium. The research results show that the cocopeat medium produced a higher success rate (15%) than the soil medium (0%). Callus appeared in the 8th week, followed by buds in the 12th week. The leaves experienced decay and drying in the 16th week, but the buds continued to grow until they bloomed perfectly in the 20th week. The failure of rachis cutting propagation using average soil media was observed from the 4th week after planting. Thus, it can be concluded that cocopeat media shows potential to support the propagation efforts of A. titanum through the rachis cutting method. The challenges of this research are influenced by pest and disease disturbances (S. rolfsii, Collembola, and H. haydeniana) due to the open research location, as well as environmental factors such as temperature, humidity, light, and pH of the growing medium.

The purpose of this study was to investigate the effect of static fluid pressure learning with Predict, Observe, Explain (POE)-oriented student worksheets on the eighth-grade students' science process skills. This research employed a non-equivalent control group design. A total of 166 students from five classes in class VIII at State Junior High School 03 in Bengkulu City represented the research population. Students in class VIII-1 (control group) and class VIII-2 (experimental group), for a total of 58 students, were selected as subjects using non-probability sampling and the convenience sampling method. By applying non-parametric inferential statistics, particularly the Mann-Whitney U test, the hypothesis was examined. The results confirm that the use of POE-oriented worksheets in learning the concept of pressure in static fluids has a statistically positive effect at the significance level (0.05) with a p-value (0.003) on science process skills, and the effect size (r=0.39) is in the medium category. The availability of worksheets that rely on scaffolding strategies such as POE may enable students in secondary schools to construct their own knowledge during the learning process.The provision of worksheets that employ scaffolding techniques, such as the Predict-Observe-Explain (POE) approach, has the potential to facilitate the development of students' knowledge construction and science process abilities in secondary school settings.
