Abstract

Data clustering is one of the methods in data science that is often used in data analysis. This method is used in making groupings from a collection of datasheets. Data clustering is done to find patterns or relationships between data. This research aims to evaluate the accuracy of data clustering using K-Means algorithm on wine datasheet. Wine datasheet has 13 features that describe the chemical characteristics of three types of wine. The clustering process must produce the best clustering evaluation metrics. The evaluation metric is done through comparison between the clustering results of K-Means algorithm with Davies Bouldin and Silhouette. The research steps involved data standardization, selection of the optimal number of clusters, and assessment of clustering accuracy. The research method uses KDD which consists of pre-processing, transformation, model building and model evaluation. Experimental results show that appropriate parameters and cluster initialization can improve clustering evaluation metrics. The clustering results show that the normalized datasheet produces evaluation metrics for Davies Bouldin 2 groups and Silhouette produces 3 groups. Before normalization, Davies Boulidin results in 7 groups and Silhouette results in 2 groups. In conclusion, this study produced different evaluation metrics between normalized and non-normalized datasheets. The selection of the number of groups chosen depends on the context of the data analysis performed and is selected into 3 groups which can be labelled "Superior Variety", the second group "Intermediate Variety" and the third group "Standard Variety".

Abstract

This article depicts the role of natural gas reserves in Afghanistan in the production of electricity in the country. Also, this study estimates the impacts of electricity generation from natural gas on imported electricity. Afghanistan has 62nd position in the world's gas reserves, 79th position in the production of natural gas, and 104th position in the consumption of natural gas. Afghanistan has 1,750,000 million cubic feet of natural gas reserves, 6,675 million cubic feet of production of natural gas per year, and 5,163 million cubic feet of consumption of natural gas per year. Afghanistan's position in imports and exports of natural gas is zero in the world. Afghanistan’s natural gas reserves are 16.2 trillion cubic feet, located in the northern Amu-Darya and Afghan-Tajik regions, and they can respond to the energy demand of Afghanistan’s people. At present, the imports of electricity from neighboring countries are 4,900 GWh per year. To carry out this study, we have used secondary data that was collected from reliable academic sources. Descriptive analysis and a quantitative approach are used for analyzing the data. The result shows that electricity generation from the natural gas reserves of Afghanistan is 1,260.45 GWh per year. This amount can reduce the imported electricity from 4,900 GWh to 2,592.55 GWh.

Abstract

In the information age like now, waves are very influential on human life. Almost all living creatures on earth are inseparable from the use of waves. One of them is X-ray and ultrasound waves. The use of X-rays and ultrasonic (USG) waves in various fields, especially in the health sector, is an important aspect of technological development. As well as its application in the medical and industrial fields. Electromagnetic waves, especially X-rays, have become an irreplaceable diagnostic instrument in visualizing the internal structure of the human body. The various benefits of X-rays are explained, from diagnosing bone fractures to radiotherapy treatment for cancer. On the other hand, ultrasound is used for pregnancy checks, monitoring the condition of the fetus, and detecting tumors and other disorders. Although ultrasound does not use direct X-ray waves, the integration of X-ray processing technology can increase image resolution and provide more comprehensive information. In this article, we will discuss several benefits of waves, namely X-ray and ultrasound waves. X-rays use electromagnetic waves with a higher frequency that are ionizing. Meanwhile, ultrasound uses ultrasonic waves with non-ionization properties. The use of X-ray and ultrasound waves includes the medical and industrial fields. The research method uses literature studies by collecting and analyzing information from various credible sources obtained from 15 journals and 3 books. The results of the literature analysis include definitions, frequencies, and wavelengths, as well as the benefits and properties of X-rays and ultrasound. Although both are rarely used, some techniques combine them to increase image resolution and clarity.

Abstract

Waves are vibrations that propagate at any time. Waves are divided into two, namely mechanical waves and electromagnetic waves. In the world of health, what we often encounter are tools whose use is accompanied by one of the physics concepts, namely optical waves. Optical waves in the world of health are very important to apply because they are the basis for learning in health science or in the sense that the concepts that are developed in health science use the concept of optical waves. Optical waves are known as electromagnetic waves, because these waves describe visible light rays, infrared, and ultraviolet rays, so these rays are used as materials for the use of optical instruments. There are many kinds of optical instruments, including loupes which are used to magnify small things, microscopes as a tool to see objects that are far away with the sense of sight, binoculars as a tool to see the distance of objects that are far from the surface of the earth, and the eye as a tool for our vision. Then scientists applied the wave concept with optical tools to serve as a reference in the world of health. Waves according to Prof. Yohanes Surya, Ph. in the title of the book Vibrations and Waves (2019), propagating vibrations produce energy and move at a certain speed, and do not drag the material they pass through. The use of optical waves is widely applied in medical science, including X-rays as a detector for internal body elements to clarify broken parts such as bones or other things. From the explanation above, it can be concluded that waves are the basis in the world of health, which are of course used in optical equipment, and are a reference for the health team and as a basic concept in physics learning. This underlies the fact that optical waves are not only used in the world of education but are very It is also needed in the world of health.

Abstract

This research was based on a phenomenon that the students’ writing ability was still low. It was assumed that there were two main factors influencing the students’ writing. One of them was about facilitating the students with appropriate written feedbacks. In line with that, this research was a kind of descriptive study, which was aimed at finding a deep description of the implementation of written feedback at MAN Koto Baru Padang Panjang. Participants of the research were all English teachers there. Furthermore, the data were collected by using two instruments, documents and interview. There were two findings of the research. First, almost all of the written feedback items were provided to help students working on their grammatical mistakes or forms of the writing, it was proven by the percentage that 99.66% of the written feedback items were focused on forms whereas only 0.34% of the written feedback items were focused on contents. Second, the technique used in giving the written feedback was written commentary. This technique was used due to its effectiveness in helping the students’ writing. In short, giving written feedback through the written commentary technique is really worth for the development of students’ writing, especially for non-native of English.
