Abstract

Tabat Barito (Ficus deltoidea Jack.) plant has secondary metabolite compounds and several bioactivities. This study was conducted to test the allelopathic activity and phytotoxicity of methanol extract of Tabat Barito leaves against Pletekan weed (Ruellia tuberosa L.) The study used a completely randomized design (CRD) in two experimental stages, namely the seed germination stage and the plant growth stage, using the concentration of methanol extract of Tabat Barito leaves: 0%, 25%, 50%, and 75%. The results showed that the methanol extract of F. deltoidea leaves was able to inhibit the germination process of R. tuberosa weed seeds. The highest allelopathic power and phytotoxicity were produced at a concentration of 75%, which is significantly different from the other treatments. At the growth stage, the methanol extract of F. deltoidea reduced biomass (wet weight 76%; dry weight 67%), chlorophyll a 50%, chlorophyll b 50%, and total chlorophyll by 71%. The higher the F. deltoidea leaf methanol extract concentration, the higher the allelopathic power and phytotoxicity against weed growth. The study showed that the methanol extract of F. deltoidea leaves was able to inhibit weed germination and growth and had strong phytotoxicity power against Pletekan weed, so F. deltoidea leaf extract has the potential to be used as a source of allelopathy or natural herbicide ingredients (bio-herbicides) that are environmentally friendly substitutes for chemical herbicides against weed plants.

Abstract

This research aimed to obtain the optimal concentration combination of 2,4-D and BAP growth regulators for inducing callus from the stem explant of Chrysanthemum (C. morifolium Ramat) in bright and dark conditions. Stem explants of chrysanthemum were grown in culture medium supplemented with various concentrations and combinations of 2,4-D and BAP under different lighting conditions for 45 days after culture. A laboratory-scale experimental method was used in this research using Completely Randomized Design (CRD). The observed parameters were induction time, percentage formation, size, fresh weight, dry weight, texture, color, and various respones generated by callus. All data were analyzed descriptively. The results showed that all concentrations and combinations of growth regulators could induce callus. In bright condition, the fastest callus induction time was 7 days after culture; most calli were dark green and dark brown colored with compact texture; the callus size was 1.36 cm; also, the highest dry weight generated by callus was 0.17 gram. Meanwhile, in dark conditions, the fastest callus induction time was 6 days after culture; most calli were light green and light brown colored with compact texture; the callus size was 1.18 cm; and the highest dry weight generated by callus was 0.15 gram.

Abstract

The objective of this study is to enhance prospective biology teacher students' species knowledge by integrating the field trip method with the indigenous knowledge of the Betawi Tribe, specifically through the skill of making educational videos. The research method employed was a one-group pre-test-post-test design. This study delineates the learning steps, namely stimulation, ethnobiological discussion, exploratory research, video artifact creation, and publication, conducted with active student involvement. The findings revealed that 66.67% of the students demonstrated proficiency in video production. The field trip combined indigenous knowledge with video-making skills, effectively enhancing students' understanding of local plant and animal species commonly used in traditional Betawi cuisine. The improvement in understanding of local plants and animals is evidenced by the increase in post-test scores compared to pre-test scores, showing a gain of 3.67 points or 16.87%. In addition, the Wilcoxon test showed a significant increase in knowledge of species after the learning experience with a Sig. (Asymp. Sig. 2-tailed) of 0.005 < Sig. 0.05. Field trips that integrated the indigenous knowledge of the Betawi Tribe with video-making skills improved students' knowledge of various species. We expect this research to contribute to improving the quality of education by integrating indigenous knowledge with the development of digital skills

Abstract

The slopes of Mount Kawi in Malang Regency had a unique ecosystem that stored valuable natural resources, including plants with medicinal properties. This research aimed to identify the diversity of medicinal plants on the slopes of Mount Kawi in Malang Regency, their utilization potential, habitus distribution, and the composition of plant parts used. The research method employed was observation with a descriptive-exploratory approach. The results revealed that the diversity of medicinal plant species and families on the slopes of Mount Kawi showed varying distribution patterns, dominated by the Rubiaceae and Fabaceae families. Four types of medicinal plant habitus were found: trees (31%), shrubs (41%), herbs (21%), and climbers (7%). Shrubs dominated with the most species, followed by trees, while climbers had the least. The composition of plant parts was dominated by leaves, with 16 types (38%) of the total utilized parts, followed by fruits and combinations of other parts, such as leaves and fruits. This predominance was attributed to the accessibility of leaves, their higher bioactive content, and their use in fresh form, boiled or extracted to treat various diseases.

Abstract

Treponema pallidum (T. pallidum) is a pathogen that causes syphilis, which is transmitted through contact with active lesions of a sex partner or an infected pregnant woman to her fetus. Despite various aggressive efforts and pharmacological treatments, syphilis has persisted and continues to be a health problem, even experiencing an increase in the prevalence of the disease in recent years. This article is based on literature studies on various research published online, especially on Google Scholar, ScienceDirect, Scopus, Pubmed, and other scientific journals. The studies were then synthesized into comprehensive information regarding specific resistance mechanisms of T. pallidum bacteria to several antibiotics. Macrolide, especially azithromycin, is an alternative treatment that is most often used in the treatment of syphilis in addition to first-line antibiotics, benzathine penicillin G injection. The use of its single oral dose, its effectiveness equivalent to penicillin, cost-effectiveness, and rare side-effect profile made azithromycin widely used in the treatment of syphilis in various regions throughout the world until treatment failures were reported. The mechanism of resistance to macrolides occurs due to modification of the antibiotic target site (binding site) caused by mutations in the 23S rRNA gene. The increase in cases and the emergence of clinically significant resistance to alternative antibiotics in some countries emphasize the urgent need for vigilance. Knowledge and understanding of the resistance mechanism of Treponema pallidum to antibiotics, especially the macrolides group, is essential in line with the increasing resistance of Treponema pallidum to antibiotics globally.

Abstract

Oxidative stress is one of the causes of heart disease, atherosclerosis, and cancer. Efforts to overcome oxidative stress include the use of natural antioxidants. Flavonoids and phenolics are secondary metabolite compounds in plants that have antioxidant activity. Plants that are believed to be able to overcome oxidative stress include Kebar grass. Kebar grass (Biophytum umbraculum) is one of the plants that empirically has many benefits including as a female fertility drug by the Kebar-Papua community. The study aimed to determine the antioxidant potential and total phenolic and flavonoid content of Kebar grass extract. Kebar grass extract was obtained through maceration extraction with 96% pro-analysis (p.a) ethanol solvent. Antioxidant testing used the 2.2-diphenyll-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) methods using antioxidant standards, namely ascorbic acid (vitamin C) and gallic acid, while measuring total phenolic and flavonoid levels used the Folin-Ciocalteu and aluminium chloride methods, respectively. The results showed that the total phenolic and flavonoid levels of Kebar grass extract were 52.26 ± 3.94 mg GAE/g dw (dry weight) and 22.15 ± 2.79 mg QE/g dw Kebar grass extract, respectively, while the antioxidants of Kebar grass extract with the DPPH method had an inhibition concentration 50 (IC50) value of 183.44 ppm and a vitamin C standard of 4.46 ppm, and antioxidant testing using the FRAP method obtained a reducing power 50 (RP50) value of Kebar grass extract of 5043.76 ppm with a gallic acid standard value of 101.8 ppm.

Abstract

This study aims to explain the use (biofuel) and toxicity of  J. curcas. This study is based on an online literature study on Google Scholar using the keywords  J. Curcas and toxicity of  J. curcas. Inedible vegetable oil (biodiesel), such as castor oil, is considered a future raw material because it is a non-edible oil and does not cause food versus fuel conflicts. The potential of  J. curcas as a biofuel is related to the oil content consisting of saturated fatty acids, palmitic acid, stearic acid and unsaturated fatty acids, oleic acid, and linoleic acid. Poisoning due to side effects of  J. curcas seeds occurs in humans, especially children and also in the environment. Symptoms of poisoning caused by  J. curcas can be analyzed through clinical signs, and the effects vary greatly, depending on the concentration, frequency, part eaten and the processing process. Accidentally ingested J. curcas seeds cause clinical syndromes such as restlessness, severe vomiting, and dehydration. Curcacycline A and curcin compound have been successfully identified from  J. curcas with antitumor activity. The potential of  J. curcas as an antitumor needs to be studied further to find alternative treatments for cancer and tumours.

Abstract

Reproductive health education is often challenging and unengaging, particularly for adolescents undergoing puberty. The lack of interactive and entertaining teaching materials further hinders effective learning. This study aims to develop and evaluate a comic-integrated handout on reproductive health for students at SMA 1 Cawang Baru. In this study, the research and development (R&D) approach was employed following Sugiyono's development model. The comic-integrated handout combines material content, comic-based entertainment, educational video links, and online tests. Validation results indicated feasibility scores of 75% (linguist), 78.33% (material expert), and 86.61% (media expert). Students' comprehension in the high category increased from 5.13% to 69.23%, while the low category decreased from 84.61% to 12.82%. Test scores improved from 44.62 to 81.03, with an overall perception score of 84.55% categorized as "Strongly Positive". These findings indicate that the comic-integrated handout is a potential and promising educational tool that improves student engagement and understanding. Therefore, we suggest this approach could be applied in future studies that focus on refining contextual relevance and expanding the approach's implementation across various educational settings.

Abstract

Coronary heart disease (CHD) remains a major cause of death globally, with its prevalence increasing over time. Diabetes mellitus is recognized as a significant risk factor for CHD. This study aims to explore the relationship between diabetes mellitus and CHD among patients at UKI General Hospital (RSU UKI). Utilizing a cross-sectional, retrospective, and descriptive-analytic design, this research analyzed medical records of CHD patients from January 2021 to December 2023, processed using SPSS software. Results indicated that CHD was most prevalent among individuals aged 60–69, with a higher incidence in men. Unemployment was common among CHD patients, and most had an education level above high school. During the study period, 79 CHD cases were recorded, with 21 patients having a history of diabetes mellitus. Data showed a consistent increase in CHD cases over the three-year period. The study revealed that individuals with diabetes mellitus were 3.5 times more likely to develop CHD. However, despite this finding, the data from RSU UKI indicated a relatively weak association between diabetes mellitus and CHD. These findings suggest that while diabetes mellitus is a notable risk factor for CHD, additional research is necessary to identify other contributing factors in this population.
