Abstract

The aim is the expected value of helium ions to determine its properties as a heat transmitter to reactors and chirogenic science. This research is non-experimental research using quantum mechanics literature study methods because there are many previous studies that are relevant to this research. Data on the expected value of electron momentum in helium ions is determined based on numerical calculations using the Matlab 2015a program to simplify calculations using ion expectation calculations in momentum. The results obtained are that the electron momentum value in the helium ion can provide an overview of the average momentum value of the helium ion electrons in momentum space. This research data also shows that in momentum space the expected value of electron momentum decreases as the principal quantum number (n) increases. This can be seen when n=1,l =0 then 3p0 = 1.3146, and when n=3,l =0 then 3p0 = 0.5098.

Abstract

Estimating rainfall accurately is crucial for both the community and various institutions involved in managing water resources and preventing disasters. The XGBoost model has demonstrated its effectiveness in predicting rainfall, but it still requires fine-tuning of hyperparameters to enhance its performance. This study seeks to determine the optimal learning rate for rainfall prediction while keeping the max_depth and n_estimator parameters fixed. The hyperparameter optimization process was carried out using a two-step approach: an initial coarse search using RandomizedSearchCV followed by a more detailed fine-tuning using GridSearchCV. The model's foundation relied on historical rainfall data gathered over three months from the Automated Weather Observed System (AWOS) at the Pontianak Meteorological Station, recorded on an hourly basis. To assess the model's performance, several metrics were employed, including accuracy, precision, recall, F1 score, and ROC-AUC. The model demonstrated promising results, with accuracy, precision, recall, and F1 score all reaching 95%, indicating its ability to effectively predict rainfall. However, the ROC-AUC score was somewhat lower at 62%. After conducting the hyperparameter search, the optimal learning rate determined for the model, utilizing the 2040 dataset, was found to be 0.204.

Abstract

The conventional laboratory learning model has proven to be inadequate in improving competencies. Therefore, there is a need to develop a learning model that integrates the knowledge gained with the skills and attitudes required when providing care, namely an integrated laboratory skills learning model. The purpose of this study was to analyze the effect of the implementation of an integrated postpartum care laboratory skill learning model on improving the competencies of Diploma-3 midwifery students. This study adopted a quasi-experimental pretest-posttest nonequivalent control group design with 79 students divided into two groups: the intervention group consisting of 39 students from STIKes Indramayu and the control group consisting of 40 students from Poltekkes BPH Cirebon. The intervention group was given the integrated learning model, while the control group was given the conventional learning model. Data analysis was conducted using t-tests, Mann-Whitney tests, and chi-square tests with a significance level of p<0.05. The results showed that the pretest competencies of the intervention group were 33 (84.6%) who were not competent, while in the control group, 35 (87.5%) were not competent. There was an increase in competencies in the intervention group by 49% (0-887) and in the control group by 19.4% (0-50.9). Further analysis indicated a significant difference in competency improvement between the group given the integrated laboratory skills learning model and the group given the conventional laboratory skills learning model (p<0.05). The conventional laboratory skills learning model was a risk factor causing students to be incompetent with a relative risk of 1.64 (95% CI 1.15-2.35) and NNT 3.2. The Integrated model of laboratory skills has a positive impact on students’ skill elevation.
