Abstract

Batak Onion (Allium chinense G. Don) is one of the species of Allium plant which is used as a flavor enhancer typical for North Sumatran Batak cuisine. In addition, the Batak onion is believed to be a health herbal remedy such as an antibacterial agent. This research aims to determine antibacterial activity of methanol extracts of Batak leeks (Allium Chinense G. Don) on Streptococcus mutans and Bacillus cereus as Positive Gram Bacteria.  The method  was the agar diffusion method. Methanol extracts of Batak leeks were diluted using Dimethyl sulphoxide (DMSO) with concentration variations (0.88, 1.66 and 2.5)%. DMSO also was used as negative blank. The research model was in Vitro experimental research model.  The results showed that methanol extract of Batak leek had antibacterial activity against S. mutans with inhibition zone diameter (5,10.5,12.7)mm and B. cereus with inhibition zone diameter (10,12.4 , 12.2)mm. The inhibition zone diameter (0) mm for the DMSO as negative blank.

Abstract

Kegiatan pengabdian masyarakat di tengah pandemi corona virus disease-19 (COVID-19) sepatutnya di lakukan secara luas, mengingat masih banyak masyarakat yang kurang mematuhi protokol kesehatan dalam rangka mencegah penyebaran COVID-19. Pemerintah Indonesia telah menetapkan langkah-langkah dan upaya pencegahan pandemi COVID-19, salah satunya adalah dengan mensosialisasikan gerakan memakai masker terutama jika berada di tempat umum. Salah satu tempat umum yang berpotensi dalam penyebaran COVID 19 ini adalah pasar dimana di pasar berkumpul masyarakat dari latar belakang yang berbeda-beda dengan kondisi kesehatan yang kita belum ketahui secara pasti. Pasar merupakan tempat untuk melakukan transaksi jual beli dalam memenuhi kebutuhan hidupnya baik kebutuhan primer, sekunder dan tersier. Untuk itu perlu dilakukan sosialisasi untuk pencegahan dengan menggunakan masker bagi pedagang maupun pembeli yang melakukan transaksi jual beli tersebut. Tujuan dari pengabdian ini adalah untuk mencegah dan memutus mata rantai penularan COVID-19 di Pasar Desa Durin Tonggal. Pengabdian pada Masyarakat dilaksanakan dalam bentuk penyuluhan penggunaan masker sekaligus membagikan masker secara gratis kepada pedagang pasar. Metode yang digunakan dalam pelaksanaan pengabdian ini adalah edukasi kepada pedagang pasar dengan menghimbau pentingnya menggunakan masker. Setelah diberikan edukasi dan pembagian masker, pedagang sudah mulai sadar pentingnya penggunaan masker di Pasar

Abstract

This research aims to determine toxicity activity test of methanol and ethyl acetate total from Batak leeks (Allium chinense G. Don). The method was using the Brine Shrimph Letality Test (BSLT). Methanol and ethyl acetate extracts of Batak leeks were diluted using salt solution with concentration variations (10, 100, 1000)ppm. Salt solution also was used as negative blank. The research model was in Vitro experimental research model. The results showed that methanol extract of Batak leeks on 6576578 mg / L which was non-toxic and LC50 on ethyl acetate extract of Batak leeks was 16.59 mg / L which was a strong toxic compound.

Abstract

Density are a physical parameter of Crude Palm Oil (CPO) quality determination which done by gravimetric method (weighing sample in a picnometer 50 mL, g/mL). Density is affected by the temperature. High temperature in CPO may cause the density become less by a little. But if we get them in lower temperature will make them in solid form and this situation is undesirable in trade industry. High temperature may cause hydrolysis reaction that add free fatty acid (FFA) content. The density changing was made with variation temperature (450C, 500C, 550C, 600C dan 650C) and FFA concentration (2%,3%,4%,5% and 6%). The result in this research was high concentration of FFA will make CPO density decreased with inreasing temperature. The linier relationship happened in same temperature (450C), the CPO density with free fatty acid content were 2%, 3%, 4%, 5% and 6% were ?= 0,8934; 0,8391; 0,8926; 0,8921 and 0,8920), so did the temperature at 500C, 550C, 600C dan 650C Keywords: Density, CPO, FFA, Temperature

Abstract

Abstract:            Research on antimicrobial and toxicity tests of flavonoid total Dendrophthoe pentandra (L) Miq from false ashoke tree (Polyalthia longifolia) have been done. This study aims to determine the activity of toxicity of total flavonoid of Dendrophthoe pentandra (L) Miq as mistletoe of false ashoke tree (P. longifolia) based on Brine Shrimp Lethality Test (BSLT) method using Artemia salina Leach shrimp larvae obtained Lethal Concentration (LC50) of 30.06 mg / L which means strong toxic activity. Antimicrobial test of flavonoid total has used the diffusion method in order to obtain the inhibit zone diameter on Streptococcus mutans at the total flavonoids concentration of 3%, 6% and 9% were 6; 9 and 17.25 mm, in Escherichia coli is 3.55; 4.25 and 9.15 mm and at Candida albicans is 8.30; 4 and 5.30 mm where S. mutans and E. coli are greater but C. albicans less affect but still have good inhibitory activity so effective to be developed as  antimicrobial agents.Keywords:false ashoke leaves, antimicrobial, toxicity, diffusion and BSLT

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

A study was done in analyzing the inhibitory activity of green tea ethanol extracts against Escherichia coli. The green tea is sourced from a tea plantation in Sidamanik, North Sumatra. The green tea was macerated with ethanol 96 % for 24 hours. After that, the filtrate was taken and then concentrated to give a concentrated extract and evaporated ethanol content until run out and obtained thick extract. The thick 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. 5.7; 7.10, and 8.05 mm The conclusion of this study is that the concentration of the extract is directly proportional to its inhibitory power, and can be used as an antibacterial agent against E. coli.
