Abstract

A study was conducted in connection with the comparison of antibacterial activity tests between ethanol extracts from green tea leaves and black tea leaves (Camellia sinensis) against Propionibacterium acnes. There were obtained by a softening technique that was softened for 24 hours. The filtrate was then concentrated to give a concentrated extract and evaporated ethanol content. The concentrated extract was then diluted with distilled water to extract 5%, 10%, and 15% concentration variations. The test method for inhibitory activity was the disc method using distilled water as a negative blank. The results obtained with blank, 5%, 10% and 15% green tea were 0. 5.25; 7.05 and 7.95 mm and black tea ethanol extract were 0; 2.50; 3.20 and 5.30 mm. The conclusion of this study is that the concentration of the extract is directly proportional to its inhibitory power, and the green tea ethanol extract is more potent than the black tea ethanol extract, so both can be used as antibacterial agents against P. acnes.

Hasil uji katalase ditunjukkan dengan ciri-ciri  tidak menghasilkan gelembung udara yang menandakan adanya BAL karena BAL tidak mengandung oksigen serta uji fermentasi yang ditunjukkan dengan tidak terbentuknya gelembung udara pada tabung Durham yang menandakan tipe fermentasi BAL adalah homofermentatif. Kata kunci : Isolasi; Karakterisasi; Bakteri asam laktat; Teh hijau; Fermentasi.ABSTRACTGreen tea is a type of tea that does not undergo a fermentation process but undergoes a process of drying and evaporation of the leaves. Green tea has high antioxidant activity due to the catechin content in it. However, the bioavailability of green tea catechins is reduced in the gastrointestinal tract because it is less stable. The presence of probiotics in green tea is expected to increase its bioavailability. Lactic Acid Bacteria (LAB) is a group of good bacteria which are probiotics that play a role in healthy gastrointestinal tract. This study aims to isolate and test the characterization of LAB from Fermented Green Tea. Green tea from Juma Tea Distributor, Sidamanik District was fermented with palm sugar and forest honey with variations of 24, 48 and 72 hours at low temperature. The fermented green tea was isolated and then diluted with 10-5 and 10-6 dilutions. The results of incubation for 48 hours were obtained and then purified by streak method and incubated again for 24 hours and then tested for morphological characterization, gram staining, catalase test and fermentation test. The results obtained were a positive morphological test of LAB with the characteristics of a single colony being seen with a round, smooth, yellowish white color, and a clear zone was formed around the colony. The results of positive LAB staining with gram-positive bacteria are indicated by a blue to purple color. The results of the catalase test are indicated by the characteristics of not producing air bubbles which indicate the presence of LAB because LAB does not contain oxygen and the fermentation test is indicated by the absence of air bubbles in the Durham tube which indicates the type of LAB fermentation is homofermentative. Keywords : Isolation; Characterization; Lactic acid bacteria; Green tea; Fermentation;

Abstract

Chemistry is one of the subjects taught in State Senior High Schools (SMAN), especially in Natural Sciences (IPA). The problem with chemistry subjects is that it is difficult to practice in the laboratory because laboratory facilities such as space, equipment and chemicals are expensive. As a result, chemical laboratory practices were only sometimes carried out. Several lecturers and students from the Department of Chemistry, FMIPA Unand Kimia Unand, carried out service activities at SMAN 16 Padang through laboratory practice using materials and equipment that were cheap and readily available in the surrounding environment. This community service aims to train teachers and students to carry out chemistry practicums using simple materials and equipment available around them. The training was given to chemistry subject teachers and students in the science laboratory at SMAN 16 on 17 and 21 November 2022. The material was practised in oxidation and reduction (redox) and electrolysis reactions. The activity went smoothly; the students enthusiastically carried out the practicum. Through the results of this simple chemistry practicum, students can design and carry out chemical experiments using simple tools and materials, conduct direct observations of chemical processes, practice scientific thinking, attitude and work skills and analyze and solve various scientific processes using scientific methods. SMAN 16 hopes that this activity will continue with different topics.

Abstract

Kirsten rat sarcoma viral oncogene (KRAS) gene mutations lead to abnormal activation of the RAS signalling pathway and have been associated with poor prognosis and resistance to some therapeutics. This study aimed to identify mutation characteristics of the KRAS genes codon 12 and 13 in colorectal cancer patients in West Sumatra. KRAS mutations were analyzed in 20 DNA of colorectal cancer patients' tissue samples by using polymerase chain reaction (PCR) with specific primer and direct sequencing analysis. Our findings showed five samples (25%) with mutated KRAS at codons 12 and 13 (including three samples with GGT→GAT, one sample with GGT→GTT in codon 12, and one sample with GGC→GAC in codon 13). In conclusion, we found two variations of amino acid changes at codon 12 (G12D and G12V) and one at codon 13 (G13D). More research with many samples is required to obtain conclusive data on the relationship between these gene mutations and colorectal cancer response to therapy and prognosis.
