Diospyros celebica leaf extract can inhibit the growth of Staphylococcus aureus and Salmonella typhi bacteria. This research aims to determine the ability of D. celebica leaf extract to inhibit the growth of S. aureus and S. typhi bacteria. S. aureus and S. typhi were grown in NA media and then given leaf extract with concentrations of 10%, 20%, 30% and 40% using the well method. 2% chloramphenicol added to the bacterial growth medium was used as a control. The results showed that the leaf extract from D. celebica has a strong inhibitory power to inhibit the growth of S. aureus and S. typhi bacteria.

This study aimed to compare two titration method (acid-base titration and iodimetri) in analyze formaldehyde at sample tofu in Gondang legi sub-district, Malang District. The research used a experimental method with added variation concentration formaldehyde in tofu filtrate. Tofu filtrate with formaldehyde then be titrated with acid-base and iodimetri method. Acid-base titration used Phenolphtalein (PP) indicator and Iodimetri titration used amylum indicator. The results of study the higher the concentration of formaldehyde the volume of titration. Titration used Iodimetri method not recommended because redox reaction at iodimetri is a slow and inaccurate reaction.

Lactic acid bacteria (LAB) play an important role in improving performance and mitigating disease because of their ability to maintain the physiological balance of the gastrointestinal tract and resistance to pathogenic bacteria. LAB is one of the bacteria found in the digestive tract. LAB must be isolated from their hosts to increase their efficiency as probiotic ingredients. This study aims to obtain local isolates of LAB a from baby feces through phenotypic identification and antibacterial test. The sample used in the research was the feces of babies aged 1-6 months that patients from Mataram University Hospital. Isolation was carried out by growing bacteria from feces using the Total Plate Count method on MRSA media plus CaCO₃. Phenotypic characterization is morphology test, gram stain and biochemical tests. The results of bacterial isolation obtained 8 isolates of LAB. LAB produced a clear zone in the MRSA media, because these bacteria were able to secrete acid in the MRSA. The results of gram staining show that all isolates are gram positive bacteria. Based on the morphology of LAB had characteristic 6 isolates of cocci and 2 isolates of bacilli. All isolates was able to produce an inhibition zone against E. coli with 3 isolates in the moderate category and 5 isolates in the weak category. The best inhibition zone in the medium category is for cocci-shaped bacteria.The existence of LAB isolates from baby feces can be used as a reference source for further research on probiotics such as other antibacterial test

High alcohol consumption in Indonesia results in increasing traffic accidents yearly. Motorbike riders and results in various degrees of injuries and result to death. This study aims to determine the differences of injuries patterns in death victims as a result of traffic accidents caused by alcohol consumption and non-consumption of alcohol among motorbike riders. This research is descriptive with secondary data from visum et repertum of traffic accident fatalities in 2015-2019 at the Forensic Medicine Installation at Dr. RSUP. Sardjito. Subjects were categorized as alcohol and non-alcohol drinkers. There were 144 cases of death among motorcyclists with 114 non-alcoholic and 30 alcoholic cases with gender, age, worker status, also number, location and pattern of injuries. It can be concluded that the victims were predominantly adult men (18-65 years). The body locations most frequently injured are the head and extremities. The wound most often experienced by victims is the vulnus excoriatum.

Blood comes from the Greek words hemato, hemo, and haima. Blood has an important role in human life. One of the examinations for diagnosing disease is a peripheral blood smear. The smear method is a microtechnical method used to make preparations. Guaranteeing the quality of the examination of blood smears is the quality of the coloring of peripheral blood smears. Giemsa dye is the most commonly used for peripheral blood smears. Giemsa contains chemicals including methylene blue, azur, and eosin. Methylene azur and eosin provide color in the cell nucleus, as does methylene blue, a cytoplasmic dye. Giemsa is not environmentally friendly and has quite high prices. This study aims to determine the effectiveness of senduduk fruit extract with concentrations of 20%, 40%, 60%, 80%, and 100% as an alternative to Giemsa staining in peripheral blood smears. The research method is descriptive-qualitative with a true experimental research design. The extract was made using the maceration extraction method, using a rotary evaporator as a means of concentrating the senduduk extract. In research that has been carried out at each concentration used, the morphology of erythrocytes is very clear. At a concentration of 100%, platelets are clearly visible. The single extract at concentrations of 40%, 60%, and 80% of the cytoplasm still appeared colored. Meanwhile, leukocyte granules were not stained at all concentrations. The most optimal coloring for senduduk fruit extract is coloring at a concentration of 80%, which is quite good at coloring red blood cells and platelets. A concentration of 100% has a clear morphology of blood cells and platelets that can be differentiated from the others

Aktivitas antibakteri propolis madu putih sumbawa terhadap pertumbuhan Staphylococcus epidermidis, Staphylococcus aureus dan Escherichia coli

Silent pandemic is a health issue related to antimicrobial resistance. Currently, deaths due to antimicrobial resistance in the world reach 700 thousand people per year and it is predicted that by 2050 it could reach 10 million people. So exploring new alternative sources is a must. One ingredient that is often used as an infection medicine and health supplement is honey propolis. Sumbawa white honey propolis is a biological product that has not yet been widely explored for its potential as an antibacterial. The research aims to determine the phytochemical content and antibacterial potential of Sumbawa white honey propolis against Staphylococcus epidermidis, Staphylococcus aureus and Escherchia coli. This research is a true experiment research with a post-test only control group design. Propolis is extracted by maceration with propylene glycol as a solvent. The concentrations of propolis extract used are 100%, 75% and 50%. Chloramphenicol positive control and 10% DMSO negative control. The antibacterial test was detected in five replications on Mueller Hinton Agar media using the disk diffusion method by measuring the diameter of the inhibition zone. Data were analyzed statistically using the OneWay Anova test. Sumbawa white honey propolis contains flavonoids, tannins and triterpenoids. The results showed that propolis was unable to inhibit gram-negative E. coli bacteria with an inhibition zone diameter of 0 mm. Different results in gram positives, Sumbawa white honey propolis was able to inhibit the growth of S. epidermidis and S. aureus. The results showed that propolis was unable to inhibit gram-negative E. coli bacteria with an inhibition zone diameter of 0 mm. Different results in gram positives, Sumbawa white honey propolis was able to inhibit the growth of S. epidermidis and S. aureus. However, Sumbawa white honey propolis against both gram-positive bacteria was in the weak category compared to the positive control. This is because all the Sumbawa white honey propolis concentration series have an inhibitory zone diameter of ≤ 5 mm.

High-intensity noise in the workplace is the cause of work stress which has an impact on decreasing work productivity, work activities, and company income. This study intends to determine the relationship between noise intensity and work stress. This study applied the analytic observational type with the cross-sectional method. The determination of the sample was through a total sampling technique. The sample in this study was 30 workers at PT. X and Y. Sound level meter was used to measure noise intensity and The Depression Anxiety Stress Scale 21 was used to measure work stress. Spearman's test was used to analyze the data. The result of the Spearman test shows that the p-value is 0.484 (p > 0.05) and the correlation coefficient is -0.133 which indicates that there is no significant relationship between noise intensity and work stress therefore H₀ is accepted and H₁ is rejected. In conclusion, there is no relationship between noise intensity and work stress on workers at PT. X and Y.
