Abstract

Salam Koja (Murraya koenigii) is a species belonging Rutaceae that contains active antibacterial compounds. These leaves can be used to kill or inhibit the growth of pathogenic bacteria in humans, namely Escherichia coli and Staphylococcus aureus. This study aims to determine the ability of koja bay leaves to inhibit the growth of Escherichia coli and Staphylococcus aureus bacteria, and to determine the concentration of koja bay leaves which is the most effective in inhibiting the growth of E. coli and S.aureus. This study used the Kirby Bauer diffusion method with 5 treatments and 5 replications. The concentrations tested were 0%, 25%, 50%, 75%, and 100%. Data analysis used one-way ANOVA test. Koja bay leaves (Murraya koenigii) can inhibit the growth of Escherichia coli and Staphylococcus aureus which is characterized by the formation of a clear zone. The 25% concentration of Salam Koja leaves (M. koenigii) has been effective in inhibiting the growth of Escherichia coli and Staphylococcus aureus bacteria. This proves that koja bay leaves contain active compounds that are antibacterial, such as alkaloids, flavonoids, tannins, saponins, terpenoids, steroids, and essential oils.

Abstract

This study discusses how students' perceptions of the Mangrove ecosystem as a source of learning biology (a study of students in class X IPA SMAN in North Gorontalo district) ". This type of research is descriptive quantitative. Data collection was carried out by means of a survey which aims to obtain data about the facts contained in this research location using a questionnaire containing written statements that will be distributed online via google form to respondents to be answered. The target of this research is the students of class X IPA of SMAN 2 Gorontalo Utara and students of class X IPA of SMAN 6 Gorontalo Utara, amounting to 1 class each. This research was conducted for 1 week. The research data were obtained from a percentage questionnaire and analyzed using the Likert score assessment criteria. The results showed that the average answers from students showed that the students' perceptions of SMAN 2 Gorontalo Utara and SMAN 6 Gorontalo Utara towards the Mangrove ecosystem which was used as a learning resource for biology, gave a very agreeable response by looking at the average answer scores, namely 4.30 and 4. , 28, while for the percentage value the average result gets a value of 78% -89% with very good category.

Abstract

Andaliman (Zanthoxylum acanthopodium) is a species belonging Rutaceae, widely used as a spice and traditional medicine, especially by the Batak ethnic group in North Sumatra. Until now, in-depth studies on the botanical and utilization of Z. acanthopodium is limited. This study is based on literature studies on various research results published online, especially on Google scholars. Some of the keys used include: Z. acanthopodium, uses of Z. acanthopodium, essential oil of Z. acanthopodium and bioactivities of Z. acanthopodium. The ethnobotany studies of Z. acanthopodium have been used in meat and fish processing which results in a distinctive flavor and longer lasting food. In the traditional Z. acanthopodium use as mouth fresheners, dental care, treat asthma, cure rheumatism, cure coughs, ingredients for making health drinks. The Z. acanthopodium has anti-cancer and anti-microbial bioactivity associated with its essential oil. The compound of dictammine and skimmianine have anticancer activity against leukemia P-388 murine cells. The activity of Z. acanthopodium as an anti-microbial is very potential to be developed as a food preservative while preventing cancer.

Abstract

Chrysanthemum morifolium contains flavonoids which have antioxidant properties and was useful in treating various diseases. The production of flavonoids from plants can be done in vitro through callus culture. Auxin 2,4-D growth regulators and organic compounds such as coconut water added to the media can affect the success of callus formation and secondary metabolite synthesis. The purpose of this study was to obtain the best treatment of 2,4-D concentration and coconut water that can increase the growth and total flavonoid levels of C. morifolium callus cultures. The method used in this research was the experimental method completely randomized design (CRD) with 8 treatments, namely 1 ppm 2,4-D + 10% coconut water (CW); 2 ppm 2,4-D + 10% CW; 3 ppm 2,4-D + 10% CW ; 4 ppm 2,4-D + 10% CW; 1 ppm 2,4-D; 2 ppm 2,4-D; 3 ppm 2,4-D; 4 ppm 2,4-D in 4 replication. The results showed that the treatment of 4 ppm 2,4-D and 10% CW was the best treatment combination, resulting in an average callus size (1.4 cm), fresh weight (0.19 grams), dry weight (0.16 gram) and total flavonoid content (1.873 mgQE/g)

Abstract

The purpose of this study was to describe the understanding of students' understanding of plant morphology and entomology specifically on the morphology and structure of insects in the Biology Education Study Program, FKIP Christian University of Indonesia. The research method is survey and content analysis. The research instrument was a non-test instrument. The data obtained are qualitative data in the form of resume biosketching and quantitative in the form of a questionnaire which is analyzed using percentage descriptive statistics. The results obtained were the first semester students with a score range of 65-80% in the understanding category, in the fifth semester students with a score of 90-100% in the very understanding category. This difference occurs because the fifth semester students have already received courses in plant morphology and entomology so that during the workshop they understand more about the morphology of the specimens drawn.

Abstract

Ascomycota is the largest Phylum in the Kingdom of Fungi. Most of the members of this group are microscopic, but fews are also produce macroscopic ascomata. Due to their large size and visible without the aid of a microscope, this group is often confused as Basidiomycota. This paper is a literature-based quantitative research. To date, 11 macroscopic Ascomycota from Indonesia have been reported, namely: Elaphomyces tropicalis sp. nov., Chlorociboria cf. aeruginosa, Podostroma cf. cornu-damae, Onygena sp., Morchella aff. deliciosa, Morchella sp., Scutellinia sp., Trichaleurina javanica, Cookeina speciosa, Cookeina tricholoma, Phillipsia sp., Daldinia spp., and Xylaria spp. The macrofungi are classified into 5 orders and 9 Families. Exploration and inventory efforts are need to be done more actively to increase the information on the diversity of masroscopic Ascomycota in Indonesia.

Abstract

Infection is a condition where the entry of microorganisms into the body's tissues, multiplies and causes disease in the form of disruption of body functions. Lemon leaves (Citrus limon (L.) Osbeck) are plants that have the potential to have antimicrobial power in the presence of bioactive compounds. The purpose of this study was to determine the antimicrobial activity of lemon fraction against Staphylococcus aureus and Escherichia coli. Ethyl acetate fraction is more effective in inhibiting bacteria, compared to ethanol and n-hexane extract based on preliminary tests conducted. Disk diffusion antimicrobial activity test (Kirby-Bauer) was used at a concentration of 5% the ethyl acetate fraction effectively inhibited Staphylococcus aureus bacteria with a diameter of inhibition zone was 12.3 mm while the Escherichia coli bacteria was 8.7 mm at a concentration of 25%. The results of data analysis using One-Way ANOVA (analysis of variance) showed a significant difference based on variations in concentration in inhibiting Staphylococcus aureus and Escherichia coli.

Abstract

Measurement of the concentration of polycyclic aromatic hydrocarbons (PAHs) compounds Benzo(a) Pyrene, Benzo(a)Anthracene, Benzo(b)Fluoranthene, Di-benzo(a,h)Anthracene, and Benzo(g,h,i) Perylene in seawater in Jakarta Bay was conducted in July-August 2015. The purpose of this study is to determine the level of pollution of five PAH compounds in seawater in their relation to the protection of marine organisms. Seawater samples were taken by using a water sampler at 23 research stations. The station position is determined by using the Geographical Position System (GPS). All samples were analyzed by using Gas Chromatography. The results showed that the concentration of the five PAH compounds in seawater in the western parts of Jakarta Bay was higher than the middle and the eastern parts. The content of the five PAHs compounds is still in accordance with the safe threshold value for marine organism life.
