Abstract

The problem with cultivating the sugarcane bud set technique is how to stimulate the rapid formation of roots and shoots. The effort that can be made is by providing growth regulators. This research aims to determine the interaction between giving NAA concentration (Napthalene Acetic Acid) and soaking time on the initial growth of sugarcane bud set seedlings. This research was conducted using a Completely Randomised Factorial Design with two factors. Factor I is the NAA concentration, which consists of four levels: zero ppm (A1), 50 ppm (A2), 100 ppm (A3), and 150 ppm (A4). Factor II is the length of soaking, which consists of four levels: 0 minutes (S1), 20 minutes (S2), 40 minutes (S3), and 60 minutes (S4). The research results showed that (1) there was an interaction between NAA concentration and soaking time, which had a significant effect on the number of leaves. The best treatment combination is an NAA concentration of 50 ppm (A2) and a soaking time of 20 minutes (S2). (2) The NAA concentration has no significant effect on any of the observed variables. (3) Soaking time has a significant effect on root volume, with the optimal treatment being 20 minutes of soaking time (S2).

Abstract

Indonesia has a very high plant diversity, with potential for bio-pesticides among these plants. Baluran National Park is a location that potentially boasts a high level of plant diversity. This study explores the potential of plants as natural pesticides in the savanna Bekol and Musim forest of Baluran National Park. The research employed an exploratory descriptive method. The data collection was conducted through observation and documentation. A total of 54 species from 28 plant families were successfully identified. Twenty-three species from 13 families have the potential to be used as biopesticides. Fourteen species were found in the Bekol savanna, and 10 species were found in the Musim forest. Pesticide plants are most commonly found in the Fabaceae family. These plants contain various compounds that offer potential for controlling plant pests. Active compounds found in these plants, including alkaloids, flavonoids, and saponins, were highlighted as potential biopesticides. The research also emphasized the negative environmental impact of chemical pesticides and the potential of plant-based pesticides as an alternative. The findings offer valuable insights into the use of natural pesticides in modern agriculture.

Abstract

Acne is a skin problem that occurs due to inflammation of the polysebaceous follicles. One of the bacterial causes of acne infection is Staphylococcus epidermidis, which is found on human skin and mucous membranes. Mahkota Dewa (Phaleria macrocarpa (Scheff.) Boerl.) is a native plant from Papua, Indonesia. Mahkota dewa leaves contain active compounds, including alkaloids, saponins, and tannins, which function as antibacterials. The objective of this research was to determine the antibacterial activity of 96% ethanol extract of Mahkota Dewa leaves against Staphylococcus epidermidis bacteria using the disc diffusion method and to determine the Minimum Inhibitory Concentration (MIC) using a UV-Vis spectrophotometer. The extract yielded 23.285% and contained secondary metabolite compounds, including alkaloids, flavonoids, tannins, saponins, phenols, steroids, and quinones. The results of the antibacterial activities were 8.98 mm, 10.24 mm, and 13.14 mm at extract concentrations of 100,000 ppm, 250,000 ppm, and 500,000 ppm, respectively. Concentrations of 100,000 ppm and 250,000 ppm indicate a moderate inhibition zone, while a concentration of 500,000 ppm indicates a strong inhibition zone against the growth of Staphylococcus epidermidis bacteria. The MIC of 96% ethanol extract of Mahkota Dewa leaves was at a concentration of 6,250 ppm with an IR% of 8.314%.

Abstract

The Gempol plant (Nauclea orientalis L.) is a plant that offers economic benefits, particularly in the wood management industry. Plant stems are one of the primary vegetative growth structures in plants. The growth factor IBA is a growth stimulant in the auxin group. The planting media used include soil, sand, and compost. This study aims to investigate the growth process of Nauclea orientalis L. stems in response to variations in IBA solution concentrations and different plant media. This study uses experimental methods with random group designs. The research activities include preparing plant media, setting up the house, preparing other ingredients, planting, and maintaining the plants. Data is analyzed using variance analysis at a 95% confidence level. Variations in response to gempol growth showed that growth development at 60 days after planting yielded different average results for the number of shoots, root length, number of leaves, leaf length, base weight, and plant dry weight. The highest average number of shoots is achieved with the combination of L3M2 and 5.3 tunas. The highest average yield of tunas was in the L3M4 combination, with 19.3 leaves. The average root length yield with the highest value is achieved with the L2M3 combination, at 20.5 cm. The result of leaf length growth has the highest average in the L0M1 combination, with a value of 21.5 cm.

Abstract

Biochemistry is one of the most challenging subjects for students to master, so a conceptual understanding is necessary to grasp its complex and broad concepts. Concept maps can help understand concepts and can also be used as an assessment tool. This study employed a quantitative correlational analysis to examine the relationship between students' conceptual understanding, as assessed through concept maps, and their academic achievement in Biochemistry. The concept map assessment utilized the University of Waterloo rubric, while the academic achievement assessment used the midterm exam results as a basis. Using the Spearman correlational test, it can be concluded that there was no statistically significant correlation between the concept map and the midterm exam score. The different knowledge content or depths likely caused this result compared to the exam. Differences in learning atmosphere, time allocated, and method of working may also contribute to the insignificant correlation between them. A further study was needed to explore the exact reason for it.

Abstract

Foliar fertilizer with an affordable market price can be utilized as an alternative medium for callus induction in Amorphophallus muelleri Blume. This study aims to compare the concentration of foliar fertilizer used as an alternative medium.  This study used different concentrations of foliar fertilizer as culture medium: full strength (3,0 g/L) and half strength (1,5 g/L) as substitutes for Murashige and Skoog (MS) medium. The media were supplemented with plant growth regulators (PGRs) 2,4-D (2,4-Dichlorophenoxyacetic acid) at 1,0 mg/L and BAP (6-Benzylaminopurine) at 0,5 mg/L for callus induction, and the study aimed to assess the effect of foliar fertilizer (Gandasil D) instead of MS (Murashige-Skoog) medium. The study used a completely randomized design with three treatments, and the data were analyzed using ANOVA (Analysis of Variance). If the ANOVA was significant at α=5%, the DMRT (Duncan's Multiple Range Test) was used to determine differences. The results showed that the formulation was Gandasil D (3,0 g/L) + 2,4-D (1,0 mg/L) + BAP (0,5 mg/L). However, it had a lower average increase in callus diameter than the Gandasil D (1,5 g/L) + 2,4-D (1,0 mg/L) + BAP (0,5 mg/L) treatment. Still, it provided a higher average increase in fresh weight and a lower browning percentage. Foliar fertilizer (Gandasil D) can be used as a substitute for MS medium to induce porang callus, but further optimization is needed by adding vitamins and organic compounds to achieve growth comparable to that in MS medium.

Abstract

The lack of students' ecoliteracy skills due to the absence of appropriate Education for Sustainable Development (ESD)-based learning materials is a significant problem that must be addressed immediately by educators. This study aims to develop and test the feasibility and effectiveness of using ESD-based learning media, in the form of e-modules, to cover the essential material on ecosystems and environmental change. The type of research used is research and development (R&D), with a sequence of potential and problem analysis, data collection, product design, design validation, design revision, product trial, product revision, usage trial, and mass production. Data were collected through tests (pretest and posttest), interviews, observations, and questionnaires. Data analysis employed both descriptive statistics and parametric inferential statistics. The study's results showed that, based on media expert assessments, the level of media feasibility was in the very feasible category, with a score of 92%. Similarly, based on material expert assessments, it was also categorized as very feasible, with a score of 94%. The level of significance obtained was 0.004 on a small scale and 0.00 on a large scale, indicating a statistically significant difference. It can be concluded that the e-module on the Geoheritage of Semarang City has been successfully developed as a sustainable development education medium that is both feasible and effective for use as a learning tool in Elementary Schools. This research product can serve as a learning medium and can be followed up on for further research.
