Abstract

Background: Humans are among the most susceptible living beings to bacterial infections. Infectious wounds on the skin surface are easily colonized by various kinds of bacteria such as Pseudomonas aeruginosa and Streptococcus pyogenes. Red spinach (Amaranthus tricolor L.) contains flavonoids with antimicrobial properties. Objective: The aim of this study was to determine the antibacterial activity of ethanol extract of red spinach leaves (Amaranthus tricolor L.) against Pseudomonas aeruginosa and Streptococcus pyogenes. Methods: This research includes the preparation, characterization, phytochemical screening of dried powder and extract. Extraction was performed by microwave-assisted extraction (MAE) method using 70% and 96% ethanol variations and then antibacterial activity of ethanol extract of red spinach leaves against Pseudomonas aeruginosa and Streptococcus pyogenes bacteria was carried out by paper disc diffusion method (Kirby-Bauer test) to obtain the diameter of inhibition. Results: The 70% ethanol extract of red spinach leaves has the lowest concentrations of 0.78 mg/ml and 25 mg/ml against Pseudomonas aeruginosa and Streptococcus pyogenes bacteria with diameters of 7.23 mm, and 7.90 mm respectively. While the 96% ethanol extract of red spinach leaves has the lowest concentration of 0.78 mg/ml against Pseudomonas aeruginosa and Streptococcus pyogenes bacteria with a same diameter of 7.43 mm. Conclusion: Ethanol extract of red spinach leaves has antibacterial activity against Pseudomonas aeruginosa and Streptococcus pyogenes.

Abstract

The mathematical problem solving ability of class VIII students at MTsN 1 kota Payakumbuh is still relatively low. The Cooperative Integrated Reading and Composition learning model is one of the proposed solutions. This article aims to describe the mathematical problem solving abilities of students who study with the Cooperative Integrad Reading and Composition learning model as being higher than the mathematical problem solving abilities of students who study with scientific learning in class VIII MTsN 1 Kota Payakumbuh. This research is a type of quasi-experimental research with a randomized control group only design. The population of this study was all class VIII at MTsN 1 Kota Payakumbuh. The research sample was class VIII.7 as the experimental class and class VIII.9 as the control class. The instrument used is a test of mathematical problem solving abilities. The test results in the experimental class mean the mathematical problem solving ability of students taught using the Cooperative Integrad Reading and Composition learning model was 79.01 and in the control class was 69.17. The data analysis technique used is the one-way t-test. Hypothesis test results using the t-test with α=0,05 at the 95% confidence level obtained t_hitung (3,43)t_tabel (1,67) then H_0 is rejected and H_1 is accepted, this means that the mathematical problem solving abilities of students who study using the Cooperative Integrad Reading and Composition learning model are higher than the mathematical problem solving abilities of students who study using scientific learning

Abstract

Toona sinensis has been used as a traditional medicine to treat diarrhea, dysentery, and fever. In the present study, the stem bark extracts of T. sinensis were investigated to determine the antibacterial activity, total phenolic content, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity, and chemical constituent using gradual extraction by maceration method with hexane, ethyl acetate, and methanol respectively. In vitro, antibacterial activity was evaluated against Staphylococcus aureus and Escherichia coli by agar well diffusion method. The hexane fraction was more sensitive to S. aureus and the ethyl acetate and methanol fractions were more sensitive to E. coli. The methanol extract showed the highest total phenolic content and antioxidant activity. Phytochemically, Toona sinensis stem bark extract contained phenolic, flavonoid, steroid, triterpenoid, and coumarin. Investigation of ethyl acetate extract produced 5,7,3',4'-tetrahydroxyflavan-3-ol (catechin). Keywords: Antibacterial, antioxidant, catechin, Toona sinensis, total phenolic content

Abstract

Agarwood oil extraction is a crucial process in the agarwood industry. However, this extraction is seldom performed by communities due to its lack of profitability and the extensive duration of the process. This study aims to investigate innovative techniques such as ultrasonic and microwave-assisted maceration to enhance the yield of agarwood oil extraction. Additionally, it seeks to calculate the efficiency of time and cost by determining the life cycle cost of agarwood oil extraction. The methodology employed in this study involved conducting extractions using ultrasonic-assisted maceration, microwave-assisted maceration, and a combination of ultrasonic and microwave-assisted maceration. The results indicated that the extraction method yielding the highest output utilized a combination of microwave-assisted maceration for 3 minutes and ultrasonic-assisted maceration for 60 minutes, producing a yield of 0.15%. When extrapolated to 24 hours, this method would yield 18 grams of agarwood oil extract with an additional cost of Rp13,037. In contrast, the solvent maceration process using microwaves yielded 0.096% of agarwood oil at a lower cost of Rp3,190, producing 12 grams of extract over a 24-hour extraction period. the compounds that make up the composition of agarwood oil are 2-((2S,4aR)-4a,8-Dimethyl-1,2,3,4,4a,5,6,7-octahydro-naphthalen (11.38%), Hydrocinnamic acid (11.13%), Hydrocinnamic acid (11.13%) and (3R,3aR,4aS,5R,9aS)-3,5,8-Trimethyl-3a,4,4a,5,6,7,9,9a-octahydro (10.90%).

Abstract

Pelayanan Informasi Aeronautika (PIA) adalah profesi yang memberikan pelayanan data-data terkait penerbangan yang berguna untuk mencegah dan mengatasi kekeliruan dalam memberikan informasi untuk mengelola data suatu bandar udara. Pelayanan informasi aeronautika tersebar di berbagai wilayah Indonesia yang bertanggung jawab atas keselamatan dalam penerbangan, keteraturan, dan efisiensi navigasi udara. Sehingga memerlukan data bandar udara yang terbaru (update) pada aeronautical information publication (AIP) Indonesia. Untuk menjalankan suatu tugas personel PIA harus melakukannya sesuai dengan SOP (Standar Operasi Prosedur), STD (Standar) yang berlaku. Pada jurnal ini penulis memakai metode kualitatif dengan pendekatan deskriptif yang berguna untuk menganalisa data yang diriah melalui observasi secara langsung lewat melaksanakan On The Job Training di PIA Wilayah Makassar.(Meldi G, 2019) (Annex 15 Aeronautical Information Services ICAO, 2018)
