Prevalence and Risk Factors for Needle Stick Injuries among Health Workers at Hospitals: A Literature Review
No full textBackground: Needle Stick Injury (NSI) is the main cause of infections in health workers that are transmitted through blood, such as human immunodeficiency virus (HIV), hepatitis B and hepatitis C. The incidence of NSI exposure in the workplace in developing countries is estimated to be much higher and most cases are not even reported. by 75%. The purpose of writing this literature review is to determine the prevalence of NSI among health workers and identify risk factors for NSI so that there is increased awareness of NSI among health workers. Method: search for articles in Google Scholar, PubMed and Crossref databases using the keywords: risk factors + needle stick injury + health workers + hospital. The inclusion criteria for research subjects are healthcare workers, articles published in 2018-2023, accessible (open access), saved in portable document format (PDF) which can be downloaded for free, and in English. Results: The prevalence of NSI in each country is different, due to the many risk factors that cause NSI.. Conclusion: by understanding the risk factors for NSI, prevention efforts can be made. Hospital management can evaluate and improve existing programs and standard operating procedures, evaluate working hours and conduct training programs related to occupational health and safety

EFFECT OF DOUBLE CHAMFER ON TESILE STRENGTH AND MICROSTRUCTURE OF AISI 304 FRICTION WELDING JOINTS
Get PDFFriction welding is a metal joining process without melting (solid state process), in which the welding process occurs as a result of combining the rotation rate of one of the workpieces with the compressive force exerted by the rotating workpiece. The friction caused by the meeting of the two workpieces will produce heat which can melt the two ends of the workpiece which are rubbing together so that they are able to melt and finally the joining process occurs. In this study, Continuous Drive Friction Welding (CDFW) was carried out on AISI 304 metal materials. This study aims to determine the effect of double chamfers on the tensile strength and microstructure of AISI 304 friction welding joints. The chamfer angle variations used are 15°, 30°, and 45°. The results of the tensile test show that chamfering can affect the results of the tensile strength. The highest tensile strength value was obtained at a chamfer angle of 30°, namely 454.9Mpa. Meanwhile, the lowest tensile strength value was obtained at the 45° chamfer angle variation, which was 193.5 MPa. The results of the microstructure test show that the chamfer angle has an effect on changes in the microstructure. At all variations of the chamfer angle, the microstructure of the weld area has perlite and ferrite fine grained phases, the HAZ region has perlite and ferrite phases larger and finer grained. Also found in all variations there is porosity. The greatest porosity is found at a chamfer angle of 45°
EFFECT OF STEAM PRESSURE AND TEMPERATURE ON THE AMOUNT OF OIL PRODUCED IN A CITRONELLA OIL DISTILLATION MACHINE
Get PDFOne of the parameters that affect the citronella oil distillation process is the pressure and temperature of the steam. The aim of this research was to determine the optimal working pressure and temperature for the distillation process. The distillation method uses the direct steam type, by varying the pressure in the boiler, namely 2 bar, 2.5 bar and 3 bar. Steam temperature increases with increasing working pressure, namely 100 - 110ºC. The raw material for citronella used 5 kg with a long distillation process of 4 hours. The test results showed that the highest amount of oil and yield occurred at a pressure of 3 bar and a temperature of 110ºC, 19 ml and 0.32%, respectively. The color of the oil produced pale yellow to brownish yellow with a specific gravity of oil at 25ºC which is 0.878 gr/ml. Citronella oil has good quality according to the SNI 06-3953-1995 citronella oil quality standards
Daya Oles, Viskositas, Tekstur, dan Warna Selai Bit (Beta vulgaris L.) dengan Penambahan Karagenan Sebagai Bahan Pengental
Get PDFBeetroots have good nutritional content for body health. Beets have the potential to be used as a basic ingredient for jam products. However, to achieve a good quality jam, it is necessary to add carrageenan as a thickening agent to improve the texture of the resulting jam. This research aims to determine the effect of using carrageenan on the spreadability, viscosity, texture and colour of beet jam products. The method used in this research was a Completely Randomized Design (CRD) with 5 treatments and 4 replications, namely giving 1% pectin as a control (P0) and giving different concentrations of carrageenan, namely 0.75% (P1); 0.1% (P2); 1.25% (P3); and 1.5% (P4) in beetroot jam. The results showed that the addition of carrageenan had a significant effect on the spreadability, viscosity, texture and colour of beetroot jam. The addition of 0.75% carrageenan can produce beet jam with better physical characteristics than other treatments
Number of Glia Cells in the Cerebrum and Cerebellum of Newborn Rats After Administration of Mackerel Fish Oil During Pregnancy
Get PDFOmega 3 intake during pregnancy can support fetal brain growth and development. Omega 3 plays an important role in making neuron cell membranes and glia and protecting nerve cells. Mackerel is a source of omega 3 which is abundant and easily accessible to the people of Indonesia. The purpose of this study was to analyze the effect of mackerel oil intake on the number of glial cells (astrocytes, oligodendrocytes, and microglia) of the cerebrum and cerebellum of newborn rats. This research was a true experimental design with a post-test only control group. A total of 30 pregnant rats were randomized into 3 groups, namely the control group (K1), mackerel oil (K2), and omega 3 supplements (K3). Each group was given treatment on days 1-17 of pregnancy. On the 18th day, the termination was carried out. 3 newborn rats were taken from each parent and made preparations from brain tissue. Hematoxylin-Eosin test to assess the number of glial cells. The results showed the highest mean±SD number of glial cells (astrocytes, oligodendrocytes, and microglia) in the cerebrum and cerebellum was the highest in the mackerel oil group (174,460±33,777; 21,080±6,937; 11,300±2,090), and (156,280 ±34,980; 22,260±4,302; 11,060±2,383). ANOVA test showed a significant difference in the number of glial cells in the cerebrum and cerebellum between groups with a p-value <0.05. The results of this study can be concluded that the administration of mackerel oil during pregnancy can increase the number of glial cells (astrocytes, oligodendrocytes, and microglia) in the cerebrum and cerebellum of newborn rats

FORECASTING THE OCCUPANCY RATE OF STAR HOTELS IN BALI USING THE XGBOOST AND SVR METHODS
Get PDFThe hotel occupancy rate indicator has become a concern in recent years as it goes hand in hand with the rapid growth of the global tourism industry. A way to maintain or even improve this indicator is to carry out managerial planning using forecasting methods. The forecasting methods used in this research are XGBoost and SVR. The advantage of this modelling is that it achieves high accuracy and processing speed. Meanwhile, the benefit of SVR is that it will produce good prediction because can overcome overfitting. The steps in this research are exploring data, separating training data and testing data, transforming data, modelling data, forecasting data, and evaluating forecasting results using RMSE, MAE, and MAPE. The results show that MAPE value from both methods is smaller than 10%, which means that both methods can predict the occupancy rate of star hotels in Bali very accurately. Apart from that, the SVR method has smaller values for all model evaluation criteria than the XGBoost method, which means that the SVR method is better than XGBoost for predicting the occupancy rate of star hotels in Bali
