<![CDATA[The Middle East Respiratory Coronavirus (MERS-CoV) is a disease caused by a coronavirus. This virus is contagious, but its transmission is not as easy as the common cold, MERS-CoV virus is better susceptible to transmitting through direct contact, for example in people who care about the MERS-CoV virus without the need for virus protection. To determine the characteristics, the MERS-CoV disease virus can be identified by identifying DNA (deoxyribonucleic acid). One technique in understanding the characteristics of life is by grouping. Grouping can be done by grouping DNA into groups that have attributes and functions. The Clustering algorithm used in this study is Partitioning Around Medoid (PAM). This algorithm has the advantage that the results of the grouping process are not by following the order of entering the dataset and overcome sensitivity to noise and outliers. The purpose of this study is to implement the Partitioning Around Medoid (PAM) clustering algorithm in clustering the MERS-CoV virus. This research was conducted through a quantitative descriptive literature study. The implementation of the PAM algorithm on the MERS-CoV DNA sequence obtained 2 clusters with the highest silhouette coefficient value on the number of clusters 2, namely 0.61534. The number of members in Cluster 1 is 84 MERS-CoV DNA sequences and the number of members in Cluster 2 is 16 MERS-CoV DNA sequences.]]>

<![CDATA[In basic physics practicums there are some simplification of cases that aim to support the understanding of physics learning concepts. In practicum implementation there is a proof process that is carried out through an experiment and involves a formulation. This can be found in simple pendulum experiments, in which there are simplified cases that facilitate understanding of the factors that affect the pendulum period value. Therefore, this study aims to prove the value of the pendulum period based on experimental results and calculation data based on formulas. The experimental method used is to use simple pendulum props and observe the effect of pendulum mass, pendulum diameter, length of the rope, and angle deviation on the value of the pendulum period. The angle variations chosen were 15o, 30o and 45o. The results obtained show that at an angle of 15o, the magnitude of the period depends only on the value of the change in the length of the rope, while at an angle of 30o and 45o, the magnitude of the angle affects the value of the period. The pendulum mass and pendulum diameter do not affect the magnitude of the period for all angular variations. Period values obtained based on experimental results and formula calculations do not show significantly different values.]]>

<![CDATA[Identifying the corona virus on international arrival passengers aims to find out whether the passenger has the corona virus or not. Corona virus is one of the health problems that really needs our attention now. Because this virus can cause death, and the way the virus is transmitted is very easy and fast. There are many things that can be done to reduce the spread of this virus to the territory of Indonesia, one of which is to identify the body temperature of each passenger on international arrivals at the airport. At the airport the identification of this virus is done by using Artificial Intelligence. One of the things that is the goal of developing artificial intelligence (AI) is to help humans. This often means imitating the abilities and intelligence of the person he is trying to help or replace. The tool used is the Thermal Scanner Camera that can see directly the body temperature of the passenger. And there are several kits that have been made to check directly whether there is a corona virus in the human body by using the Rapid Test and PCR Test. This research was conducted to see how important AI (artificial intelligence) is in helping reduce the spread of corona virus. According to some existing data, the use of Thermal Scanner Camera can help reduce the spread of corona virus at airports.]]>
