Abstract

Efforts are necessary to mitigate students' limited understanding of and difficulty in learning about Protista via Student Worksheets (LKS). The creation of such worksheets can be achieved by integrating Protista identification into the surrounding environment. The objective of this research is to identify Protista in the environment of SMA N 42 Jakarta and Universitas Kristen Indonesia as educational resources. Additionally, this study aims to describe the results of the Student Worksheet (LKS), which underwent validation by both validators and students. The research utilized field exploration and development methods. The identification of pond water samples yielded four species: two microalgae and two protozoa. The results of this identification were developed in the LKS uploaded on the ResearchGate link, namely https://bit.ly/LKSprotistaradeetal. The worksheet underwent validation by three reviewers and was deemed feasible with a score above 75%. Additionally, the student feedback was largely positive, with an approval rate exceeding 70%. Thus, the Protista Diversity LKS is expected to be a groundbreaking tool for advancing biodiversity and classification education in 10th-grade classrooms.

Abstract

The need for red onions has not yet been balanced by the amount of production, so the government always brings in red onions through imports to meet the community's needs. The aim of this research was to determine the effect of the growth of shallots (Allium ascalonicum) on the application of liquid organic fertilizer from sap (Arenga pinnata). The approach used in this research is quantitative research. The research was carried out using a completely randomized design (CRD) with different concentrations of liquid organic fertilizer from palm sap, with concentrations of 0 ml, 20 ml, 40 ml, 60 ml, 80 ml and 100 ml, a total of 6 treatments, with 5 replications. The results of the research show that based on the ANOVA test, the calculated F value was 1,954, while the F table (0.05) on the diameter of shallot plant bulbs shows that there is a significant influence provided that F calculated>F table. Apart from that, based on the results of the anova test, the parameters of plant height (0.178), the significant value of the number of plant leaves (0.067), and the significant value of the diameter of the plant tuber (0.133) so that the research results obtained indicate that liquid organic fertilizer of sugar palm sap has an effect on height growth. plants, number of leaves, and diameter of shallot bulbs (Allium ascalonicum).

Abstract

Metacognitive skills are one of the skills that can influence people's lives and ways of thinking regarding self-management. This research aims to describe students' metacognitive abilities, especially in class XI biology subjects at Nahdlatul Wathan Mataram High School, which consists of classes XI MIA and XI IIS. Data collection was carried out using a questionnaire by looking at metacognitive skills from three aspects, namely planning, monitoring and evaluation. Based on these three aspects, it shows that class XI students at NW Mataram High School do not have low category metacognitive skills or are not well developed. Based on the results of the questionnaire scoring, it was found that on average students answered sometimes or never. This shows that their awareness of planning, monitoring and evaluating their learning process is very low and of course this also has an impact on learning outcomes. This is what requires teachers to be able to implement learning that can develop students' metacognitive skills, so that learning outcomes will increase.

Abstract

Forests are important habitats that support an ecosystem consisting of various types of plants that have production potential and litter decomposition rates. This research aims to find out how to calculate the production and decomposition rate of litter in homogeneous forest and heterogeneous forest terrestrial ecosystems. The research was carried out in homogeneous and heterogeneous forest areas in the IPB University campus area, Bogor Regency, West Java Province. The sampling process seemed to be carried out using 1x1 m nylon mesh litter trap method for 5 weeks. The results of the research show that the composition of the species that grow in heterogeneous forest areas is Kisabun (Filicium decipien), Sawo kecik (Manilkara kauki), Bisbul (Diospyros blancoy), Water guava (Eugenia aduea), Matoa (Pometia pinnata), Pinus (Cupressus lusitanica), and Meranti (Shorea sp), while in the homogeneous forest ecosystem is the rubber tree (Hevea brasiliensis). The amount of waste collected in heterogeneous forest ecosystems is greater than in homogeneous forest ecosystems (Rubber forests), namely 98 grams and 5.2 grams respectively with results in heterogeneous forest ecosystems of 7.2 grams dry weight from 10 grams wet weight, whereas in homogeneous forest ecosystem (rubber forest 0.8 grams dry weight from 2 grams wet weight). The decomposition rate of litter in heterogeneous ecosystems is 0.21 grams/year, while in rubber forest ecosystems it is 0.17 grams/year.

Abstract

Zingiberaceae is an aromatic plant that has the potential to produce essential oils. One of the species is Elingera doliiformis. Etlingera doliiformis A.D. Poulsen is an endemic species to Sulawesi from the Zingiberaceae family. This study is the first to examine the antioxidant potential of E. doliiformis. The aim of this research is to obtain the antioxidant capacity value of the endemic plant of Sulawesi, namely E. doliiformis. The plant materials used are leaves and flowers. Antioxidant capacity analysis was carried out using the DPPH (1,1-diphenyl-1-picrylhydrazyl) method. The vitamin C antioxidant test was carried out by dissolving 20 mg of vitamin C in 100 ml of 96% ethanol. The antioxidant activity of E. doliiformis flowers and leaves was determined using the DPPH test. The percentage of inhibition in flowers was higher than in leaves, although the difference was not significant. The results of the analysis of the antioxidant capacity of Etlingera doliiformis leaves and flowers showed high antioxidant potential. This potential can be used as a development in the pharmaceutical industry in the future.
