Abstract

Philosophy and science are human efforts to understand the concepts and methods of a scientific discipline. Changing times and developments have ushered in a philosophy of configuration by showing how the "tree of knowledge" thrives and branches out from the respective disciplines. This study aims to examine philosophy and science and their relevance in the Industrial Revolution 4.0 era. This research method uses the hermeneutic method in explaining the reality that occurs with elements of interpretation and description. The results of the research can be described that the study of the relationship between philosophy and science has developed so rapidly. Philosophy and science are indispensable in the development of science and technology which is marked by sharpening of scientific specialization, because by studying philosophy scientists are expected to be aware of its limitations so as not to get caught up in intellectual arrogance. It is impossible to fight against the discourse on the development of science and technology, but rather to reduce the negative impact of technology itself. In the era of the Industrial Revolution 4.0 and Society 5.0, community groups are heterogeneous, so that very complex problems arise related to technological developments and can change the mindset of human life to patterns of life that are more sophisticated with the power of technology. like robots and the internet. Thus, science which is used as an axiological milestone in directing and controlling the development of science and technology in a positive way for the benefit of humanity and its environment is philosophy and science.

Abstract

Along with the development of science and technology, some researchers try to apply knowledge to several biological systems to obtain benefits that can be used. One of them is the use of ultraviolet light to kill the fungus Aspergillus niger. In addition, ultraviolet rays are also used in various fields of the drinking water industry, food, and also for sterilizing operating rooms in hospitals. A method used in this problem is the cork borer method. Data were obtained by measuring the diameter of the inhibition zone of the Aspergillus niger fungus. The results of this study were obtained at the intensity of 12.30 lux and at a distance of 15cm, within 15 minutes of irradiation time, the maximum death of the fungus Aspergillus niger was 40.74%.

Abstract

Research has been conducted on the effect of Multi Leaf Collimator (MLC) on the dose received by the head of brain cancer patients at Sanglah Hospital, Denpasar. This analysis aims to determine the effect of using MLC on dosing to brain cancer patients using Cobalt 60 (Co-60) teletheraphy. The dose given at TPS was 200 cGy but after using MLC the dose was received because MLC protects healthy organs around the irradiation field. If the dose given is still within the range of -5  % and +7  %, it is still acceptable. The amount of radiation dose that can be reduced by using MLC in this study was 1,35 % for brain cases and 0,12 % for Glioblastoma cases.

Abstract

This analysis examines the relationship between the number of solar flares and the number of sunspots in 2005 using 11 observations in months 2 to 12. The number of solar currents measures the intensity of the radiation emitted by the Sun, while the number of sunspots measures the number of sunspots on the surface of the Sun. Multivariate linear regression analysis was used to analyze the relationship between Solar Current Rate and Number of Sunspots. The results of the analysis show that the coefficient of the Amount of Solar Current is 1.1239 with a significant t value of 2.510 (probability that there is no effect on the Number of Sunspots is 3.33%). The linear regression model has good results with an F-statistic value of 6.301 and a p-value of 0.0333, with an R-squared value of 0.4118 which indicates that 41.18% of the variation in the number of sunspots is influenced by variations in the amount of solar currents. The corrected R-squared value is 0.3464 indicating that there are still variations in the number of sunspots that cannot be explained by variations in the number of solar currents. ARIMA analysis results show an MA coefficient of 0.7351 with an average value of 45.9542 and a s.e value of 0.2590 and 6.1550 respectively. The AIC, AICc, and BIC values are 92.97, 96.4, and 94.16. The error results in the training set show that the ME value is 0.2615561, the RMSE value is 12.16969, the MAE value is 9.03306, the MPE value is -15.14689, the MAPE value is 30.42013, and the MASE value is 0.674109. The ACF1 value in the exercise set is 0.0808969.

Abstract

CT scan -Scan Those originating from X-rays on the head are very risky considering that the tissue in the brain has a greater sensitivity to ionizing radiation when compared to other organs in the human body. Problems will then arise when the use of CT-Scan sourced from X-rays can pose a radiation risk. Based on research conducted by Mathews et al. (2013) reported that at least 680,211 patients who had performed CT-Scan, 3,150 patients were diagnosed with cancer. There is a more accurate method in estimating the dose received by patients, namely using the SSDE. The dose estimation method using SSDE considers geometric factors (body size). The purpose of this study was to see how weight, gender, and age affect SSDE, using 80 patients classified into 4 age groups (children, adults, elderly, and seniors). The results showed that the average effective dose for children was 4.065 mSv for males and 3.706 mSv for females with a significant effect of weight, sex, and age on SSDE because theFCount as big4,640    FTableof 2.215
