Abstract

Digitalization is needed by manufacturing companies in organizing sustainable, data-driven, effective and efficient, safe defence and security equipment production activities. Utilization of Internet of Things (IoT) in Indonesia is said to still have many deficiencies, resulting in many cases of data leakage, both government and private sector data. The purpose of this research is to review the conditions of the use of the IoT in various industrial sectors, the challenges, and the potential for development in the Indonesian defence industry. A literature review approach is combined with a qualitative method in this study. The results of this study found that the application of IoT to Indonesia's defence industry is necessary in order to increase the level of local content, complement and strengthen defence and security equipment, and reduce the burden of production activities. In addition to production needs, IoT can filter information or data on weapons or combat vehicles when used in field tasks and then become the basis for making subsequent products.

Abstract

This research explores and focuses on the nursing profession, because there is still a lack of research in knowing the relationship between nurse leadership styles and nurse performance. Data collection by interviews, questionnaires and observations on inpatient nurses at Rotal Prima Hospital Medan. This study tries to examine the influence of the Job Performance Nurse dimension which is influenced by the dimensions of the Transactional Leadership Style and the Transformational Leadership Style of Head Nurses. This research is associative, with a quantitative method approach, using a descriptive correlational research design. The research was validated using SPSS-26 with data analysis techniques using multiple linear regression analysis. The results showed that the Transactional Leadership Style and Transformational Leadership Style had a positive and significant effect on Nurse Job Performance. The results of this study, we found that nurse leaders must have a good transformational leadership style so that leaders can help and encourage their subordinates in providing training and achieving their work goals properly. Nurse leaders are more likely to adopt a transformational leadership style. The results of this study also show that transactional leadership can affect nurse performance, although it is even better if the head nurse performs transformational leadership.

Abstract

The existence of clean water is very important considering the very dynamic activities of people's lives. Therefore, the quality and quantity must be considered. Clean water that meets health requirements must be free from pollution and must meet quality standards: one of them is physical requirements because drinking water that does not meet quality standards can cause health problems. The topography of an area can affect groundwater in that area. This study aims to analyze differences in the quality of well water in the highlands of Rantauprapat City and the lowlands of Rantauprapat City based on physical parameters. The research was conducted at the BTKL Physics Laboratory in Medan in October 2022. The method in this research was observational analytic with a cross-sectional approach. The sample was determined by purposive sampling which amounted to 50 samples. Data were analyzed using SPSS 21 and the Mann Whitney-U Test. The results showed that there was no significant difference in water quality in the parameters of taste, temperature, odor and turbidity with a p value > 0.05, while there were significant differences in the parameters TDS and DHL with a p value <0.05. Conclusion: There are no significant differences in water quality in the parameters of taste, temperature, odor and turbidity, while in the TDS and DHL parameters there are significant differences in water quality with a p value <0.05. 0.05 while the TDS and DHL parameters are significantly different with a p value <0.05. Conclusion: There are no significant differences in water quality in the parameters of taste, temperature, odor and turbidity, while in the TDS and DHL parameters there are significant differences in water quality with a p value <0.05. 0.05 while the TDS and DHL parameters are significantly different with a p value <0.05. Conclusion: There are no significant differences in water quality in the parameters of taste, temperature, odor and turbidity, while in the TDS and DHL parameters there are significant differences in water quality with a p value <0.05.

Abstract

Jet-1 Agribun is one of the Indonesian Jatropha new varieties suitable for rainfed areas with a high yield of dry seed and oil content. The field trial was conducted at Asembagus Experimental Station in Situbondo, East Java from February to December 2019 and aimed to observe the potential of Jatropha Jet-1 Agribun under rainfed conditions. Observation on seed yield and growth components of Jatropha plantation was also made in two and three years old Jet-1 Agribun. Results of the observation showed that Jet-1 Agribun in the first year produced seed 471.8 kg/ha. A two-year-old plant produced a dry seed of 3,958.7 kg/ha. Three-year-old plants after pruning produced dry seed 910.95 kg/ha and 916.04 kg/ha at 1 m x 1 m and 2 m x 2 m, respectively, indicating that wider spacing is more allowable for cropping with food crops until the canopy closes. Development of Jatropha should be integrated with food crops or other crops through intercropping systems, by using the land around the plants until the canopy closes.

Abstract

The Correlated Naïve Bayes Algorithm is a statistical learning method that has shown promise in predicting the healing rate of hepatitis patients. Hepatitis is a liver disease that can be chronic or acute and affects millions of people worldwide. The healing rate of patients with hepatitis can vary widely depending on various factors such as age, gender, and medical history. The Correlated Naïve Bayes Algorithm takes into account the correlations between the different attributes of patients and their healing rates, unlike the traditional Naïve Bayes Algorithm. This approach has been shown to improve the accuracy of predictions significantly. In this study, the Correlated Naïve Bayes Algorithm was applied to a dataset of hepatitis patients. The dataset contained information about patients' age, gender, medical history, and other attributes that might affect their healing rates. The algorithm was trained on this dataset to predict the healing rate of new patients. The results showed that the Correlated Naïve Bayes Algorithm achieved higher accuracy in predicting the healing rate of hepatitis patients compared to the traditional Naïve Bayes Algorithm. This suggests that the Correlated Naïve Bayes Algorithm could be a useful tool for healthcare professionals in predicting the healing rate of hepatitis patients, and ultimately improving their treatment and care. Furthermore, the study also investigated the importance of different attributes in predicting the healing rate of hepatitis patients. The results showed that age and medical history were the most important factors, followed by gender and other attributes. The findings of this study have significant implications for the medical community, as accurate prediction of healing rates can inform treatment decisions and improve patient outcomes. The Correlated Naïve Bayes Algorithm provides a powerful tool for healthcare professionals in predicting the healing rate of hepatitis patients, and could be extended to other medical conditions. However, it is important to note that the Correlated Naïve Bayes Algorithm has limitations, such as the assumption of independence between attributes. Therefore, future research should investigate alternative methods that can overcome these limitations and improve the accuracy of predictions further.
