Abstract

The basalt of "Ohi" Mount and the Andesite Hornblend on "Ser" Mount are a barrier to the flow of groundwater from "Ifa" Mount. Both are an influence on the productivity aquifer. The characteristic of lithology in water is an influence of the permeability coefficient. Falling head is one of the methods of measuring the determination of coefficient permeability. Based on the location measurement, To know the units of rock formed, (2) To know the Productivity aquifer system (local, medium and small); (3) To know the coefficient permeability of characteristics of lithology. Coefficient of Permeability A stream is said to be good if the nature of the rock type has a positive result or the greater the water pass rate, and conversely, the passing value of a negative result has a very small water pass rate. Its goal was to determine the relationship between lithology characteristics and permeability coefficients in the "BRG" area and surroundings. The "BRG" area and its surroundings, based on the location point of measurement of the rock unit, were the Breccia Andesite Hornblend unit, The Medium Productivity Aquifer Dominated. The average coefficient of permeability (K) is 63,300 cm/day. The five location measurements were: 1 st area DS, S1, 2 nd DS area, S2, 3 rd DN area, 4 th DD area, and 5 th DR. The aquifer of the five locations had through fracture permeability and had a type of steep hill morphology

Abstract

During the COVID-19 pandemic, many infectious diseases other than COVID-19 are often neglected in their spread. One of the most common infectious diseases is Sexually Transmitted Infections (STI). STIs are reproductive tract infections caused by bacteria, viruses, and parasites, most of which are transmitted through sexual contact. The high incidence of STIs shows that the public's knowledge of STIs is still low. This study aims to determine the use of drugs and the characteristics of STI patients during the COVID-19 pandemic in 2020-2021 at RSUD Abdul Wahab Sjahranie Samarinda. This research is non-experimental. The research method used is descriptive quantitative, which is done retrospectively. The results showed a decrease and increase in the number of patients during the COVID-19 pandemic. The total number of STI patients in this study was 48 patients, consisting of 17 patients in 2020 and increasing to 31 patients in 2021. The most characteristics of STI patients during 2020-2021 are male patients, the majority of STI patients aged 17-25 years, high school education level, working as private employees, and unmarried. The most common types of STIs in 2020 were gonorrhea and syphilis in 2021. The most frequently used drug for the treatment of syphilis was the injection of benzathine penicillin, for the treatment of gonorrhea was azithromycin, for the treatment of condyloma acuminata was cefixime and for the treatment of genital herpes was acyclovir.

Abstract

Endophytic bacteria have been extensively studied as a source of new antimicrobial compounds. Research into new antimicrobials is important as an alternative to the treatment of resistant microbes. One potential source of antimicrobial compounds is the Taxus (Taxus sumatrana). This study aimed to investigate the antimicrobial activity produced by the endophytic bacteria of the Taxus. Endophytic bacteria were isolated from the roots of Taxsus plants growing in Mt. Singalang, X Koto District, West Sumatra. Bacteria were isolated by inoculating pieces of Taxus root tissue into a PDA medium. Endophytic bacteria were identified macroscopically and microscopically. Antimicrobial activity was tested with the test microbe using the spot test diffusion method. As a result of the research, 23 isolates of endophytic Taxus bacteria were obtained, of which 21 isolates were gram-positive and 2 isolates were gram-negative bacteria. The results of the antimicrobial activity test yielded only 2 isolates of endophytic bacteria with antibacterial activity.
