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.

Abstract

ABSTRAKTeh hijau adalah jenis teh yang tidak mengalami proses fermentasi akan tetapi mengalami proses pengeringan dan penguapan daun. Teh hijau memiliki aktivitas antioksidan yang tinggi karena kandungan katekin di dalamnya. Namun bioavaibilitas katekin teh hijau berkurang pada saluran cerna karena kurang stabil. Kehadiran probiotik pada teh hijau diharapkan mampu meningkatkan bioavaibilitasnya. Bakteri Asam Laktat (BAL) merupakan kelompok bakteri baik yang merupakan probiotik yang berperan dalam menyehatkan saluran cerna. Peneltian ini bertujuan untuk mengisolasi dan menguji karakterisasi BAL dari Teh Hijau Fermentasi. Teh hijau yang berasal dari Distributor Teh Juma, Kecamatan Sidamanik difermentasi dengan gula aren dan madu hutan dengan variasi waktu 24, 48 dan 72 jam pada suhu rendah. Teh hijau fermentasi kemudian diisolasi kemudian diencerkan dengan pengenceran 10-5 dan 10-6. Hasil inkubasi selama 48 jam diperoleh kemudian dimurnikan dengan metode streak dan diinkubasi kembali selama 24 jam kemudian diuji karakterisasinya secara morfologi, pewarnaan gram, uji katalase dan uji fermentasi. Hasil yang diperoleh adalah pada uji morfologi positif BAL dengan ciri-ciri terlihat koloni tunggal dengan bentuk bulat, licin, warna putih kekuningan.dan terbentuk zona bening di sekitar koloni. Hasil pewarnaan positif BAL dengan ciri-ciri bakteri gram positif ditunjukkkan oleh warna biru ke ungu. 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

Epigallo catechin gallate (EGCG), a catechin bioactive component found in green tea, has been used widely as a popular beverage in Asian nations for centuries. According to a summary of five years’ worth of recent papers, EGCG has a wide range of positive benefits including anticancer, anti-cholesterol, cardiovascular agent, anti-virus, antioxidant, and adjuvant treatment agent. The purpose of this literature review is to get more knowledge on EGCG, the most prevalent catechin derivative found in green tea. A substance with significant antioxidant capabilities, EGCG has a wide range of applications. However, EGCG also has a number of drawbacks in addition to its benefits, such as low stability, poor absorption, and the requirement for a daily intake restriction because it acts as a pro-oxidant and can be harmful if consumed in excess. As a result, authors attempt to mitigate undesirable effects and discover a way to maximize EGCG benefits through additional study that serves as research material. Furthermore, we are becoming research subjects in order to against the negative effects of EGCG, such as how to use probiotics to boost the absorption of EGCG during digestion.

Abstract

This study aimed to determine the yield of activated carbon, iodine number, and surface area of palm activated carbon. Samples were produced by using sodium chloride (NaCl) as an activator. Palm shells that had been produced by the milling process were then sieved with a 12 mesh sieve and soaked in 20 % NaCl solution. The sample solution was heated over a water bath at 70 oC and continued with the drying process at a constant temperature of 105 oC. The activated shells continued the pyrolysis process at temperatures of 300, 400, and 500 oC for 3 hours. The activated carbon obtained from the pyrolysis process was weighed and then washed using hot distilled water. The samples were dried in an oven at a temperature of 105 oC for 24 hours. The results were analyzed for iodine number using iodometric titration method, surface area using Brunauer- Emmett-Teller (BET) method, and pore structure using the Scanning Electron Microscope (SEM) method. The results showed the best yield was 38.13 % obtained at 20% NaCl and a temperature of 400 oC. The best iodine number was 767.745 mg/g and surface area was 6.790 m2/g, pore volume 4.377 cc/g with pore size 9.781 A.
