Abstract

The agricultural sector, especially oil palm plantations, has an important role in the Indonesian economy. Oil palm farming has increased the welfare of farmers and provided employment. In this study, researchers used the C4.5 and K-Nearest Neighbor algorithms in the RapidMiner application to analyze oil palm fruit production data after going through the data preprocessing process. The C4.5 algorithm produces a decision tree with an accuracy of 94.12%, while the KNN algorithm achieves an accuracy of 82.53%. Based on these results, it can be concluded that the C4.5 algorithm has a higher accuracy in classifying oil palm fruit production based on existing attributes.

Abstract

The cement industry is one of the most important industries in the development of a country. However, the production activities of the cement industry also cause significant environmental impacts, one of which is air pollution. One of the by-products of fuel combustion in the cement industry is fly ash, which if not managed properly can pollute the air and the surrounding environment. This research aims to provide an overview of the environmental impacts of using fly ash in the cement industry, especially in relation to air pollution. This research uses the literature review method, which is by collecting and reviewing literature or documents related to the research topic. The data sources used in this research are scientific journals, books, and other related documents. Data analysis in this study was carried out by reviewing and examining literature or documents related to the research topic, then summarizing and compiling the results of the analysis into an overview. Based on the results of this study, it can be concluded that the use of fly ash in the cement industry has significant environmental impacts, especially related to air pollution. However, there are several technologies and fly ash processing methods that can reduce the environmental impact of cement industry production activities, such as the use of fly ash as raw material for making lightweight concrete or as raw material for the production of other building materials.

Abstract

Education is one way that can be used to increase one's knowledge. Education can be given in various fields, including health. The purpose of this study was to determine the effect of Health Education on increasing the knowledge, attitudes and behavior of elderly people with hypertension in the Pangkajene Health Center area in 2023. This type of research used a quantitative method with a pre-experimental design study with pre-test and post-test design treatment, while the population was patients 90 people who suffer from hypertension at the Pangkajene Health Center use total sampling. The results of this study used the Wilcoxon test analysis. Knowledge was -8.132 and a significant value was 0.000 (p<0.05), Attitude was -8165 and a significant value was 0.000 (p<0.05), and Behavior was -8267 and a significant value was 0.000 ( p<0.05), there was a significant difference in the results of the Health Education pretest and posttest on the attitudes of the elderly with hypertension in the Pangkajene Health Center area. The results of this study indicate that there is an effect of Health Education on the attitude of the elderly who experience hypertension in the Pangkajene Health Center area. The conclusion of the study showed that there was an effect of Health Education on the knowledge, attitudes and behavior of elderly people with hypertension in the Pangkajene Health Center area. it is expected that the puskesmas will carry out home care because elderly people with hypertension cannot carry out health checks because there is no family to take them to health services because they are busy with their daily activities.
