Abstract

The data that have been obtained in Indonesia by using samples of clinical material from the hospital, Staphylocccus aureusis proved to be resistant to penicilin and methicillin, tetracyclin, oxacilin, gentamicin, erytromycin, chloramphenicol, and trimethrophrim-sulfemethoxazole. The high resistant inStaphylocccus aureus bacteria encourage efforts to find drugs that have antibacterial activity. Furfural and its derivates are known to have antibacterial activity. The purpose of this study was to obtain derivate of furfural compound 2,6-bis-(2’-furilidyn)-sikloheksanone, which is expected to have antibacterial activity against drug resistant bacteria Methicillin resistant Stapylococcus aureus (MRSA). 2,6-bis-(2’-furilidyn)-sikloheksanone synthesis was done with starting materials ofcyclohexanone (0,0121 mol)and furfural (0,0121 mol), using KOH 7,5% as catalys in the aquadest solvent. The purity test were carried out with melting distance test, thin layer chromatography, and gas chromatography. Structure elucidation was performed with mass spectrometer analysis, IR, and spectrophotometer, H1-NMR. The syntesis result is then tested for its antibacterial activity againts MRSA bacteria with diffusion method to determine the inhibition diameter. The result of this study showed that 2,6-bis-(2’-furilidyn)-cyclohexanone has been successfully synthesized with an average yield of 73,60% ±0,204. Re-crystallization resulting in pure compound base on its melting range (1,90C), TLC (one spot Rf= 0,33), and GC (100% area). The results of the chemical structure elucidation by mass spectrometry, IR spectrophotometerand H-NMR spectrometer line with the target compound. The synthesis result has antibacterial activity with average of inhibition diameter at a concentration of 3,959mM/ml= 27 mm.   Keywords:synthesis, analog of curcumin, antibacterial

Abstract

Introduction: Diabetic gangrene can be treated with antibiotics. The use of antibiotics must be done rationally. Antibiotic sensitivity patterns know which antibiotics have become resistant. The purpose of this literature study is to determine the relationship between rationality and patterns of antibiotic sensitivity in bacteria that cause gangrene infection. Methods: The research was conducted using a literature study method using journals obtained through journal sites such as search engines Scopus, Google Scholar, ScienceDirect, NCBI, PubMed, Oxford Academics, Cambridge, and Sprinkle link published between 2009-2021, obtained journals as many as 13 journals extracted from 99 existing journals. This literature study was carried out in several stages, namely, formulating problems, collecting data, extracting data, synthesizing data, and compiling a thesis. Result: The results of the literature study rationality of antibiotic use is precise indication, appropriate drug and appropriate patient. Antibiotics that are resistant in several hospitals in Indonesia are ceftriaxone, cotrimoxazole, benzylpenicillin erythromycin, ampicillin, cloramfenicol, cefoperazone, meropenem, cefixime, gentamicin, ceftazidime, ciprofloxacin, streptomycin, lincomycin, and cefotaxime. The mechanism that bacteria have in developing resistance is by enzymatic modification, changes in PBP structure, pump protein production, and changes in antibiotic targets

Abstract

The high residualvalue of drug inventory at IFRS RSIS Mojokerto indicates that drug management has not been managed optimally. The priority scale of supervision and control at planning stage needs to be carried out using the ABC-VEN method analyzing and calculating the EOQ value in order to achieve the most economical ordering value to avoid overstock. The purpose of this study was to determine drug classificationusing the ABC-VEN method, planning control using with EQQ and measuringthe efficiency value at IFRS RSIS Mojokerto. The design of this research is descriptive quantitative. Retrieval of retrospective data from the January-October 2020 financial statement at IFRS RSIS Mojokerto. The data were analyzed by ABC-VEN to get categoryA drugs. Drug inventory control was calculated by calculating the value of EOQ,ROP, efficiency value by calculating ITOR. The results of drug classification using the ABC-VEN method obtained categoryA drugs absorbing 68.05% of the total investment value. Control of planning category A drug needs resulted in the value of the remaining inventory dropping from 48.4% to 36% of the total inventory value, ITOR increased from 2.0 to 4.1 times per month. The conclusion of the ABC-VEN, EOQ and ROP analysis can be used to determine the priority scale of procurement and control to avoid over-stocking of drug supplies in the hospital.

Abstract

Soursop is a traditional medicinal plant used as a therapy for hypertension. One of them is Flavonoids which work as ACE inhibitors which will inhibit the change of AIR into AIR thereby reducing the secretion of antidiuretic hormone (ADH ) thus causing a drop in blood pressure.This study aims to determine the effect of boiled soursop leaves on reducing blood pressure in elderly people with hypertension in the Sukawangi Village area, Warungkondang District, Cianjur Regency in 2023. This research uses a quantitative experimental research method using a quasi-experimental design with pre and post using a one group pre test and post test design. The population in this study was elderly people suffering from hypertension in the Sukawangi Village area, Warungkondang District, Cianjur Regency with a sample of 17 people. The analysis used is Univariate and Bivariate using the Paired Sample T test. The blood pressure of hypertensive patients before being given soursop leaf decoction treatment to obtain information on the Mean Arterial Preasure value) before being given the intervention, the mean MAP value was 124.09 mmHg from 17 respondents. After being given the intervention, the results obtained were an average MAP value of 95.24 mmHg.That there is an effect of boiled soursop leaves on reducing blood pressure in elderly people with hypertension in the Sukawangi Village area, Warungkondang District, Cianjur Regency in 2023. Should be more overcoming the problems of the Indonesian people due to the increase in patients with hypertension.
