Abstract

Puberty in teenage girls is usually marked by menarche or first menstruation. Menstruation is a process of shedding of the lining of the uterine wall. There are several factors that cause abnormal menstrual cycles such as stress, nutritional problems, hormonal disorders and also chronic diseases. Personal hygiene during menstruation is also important for women. If a woman's personal hygiene is not maintained properly, it is likely that infections will occur in the reproductive organs. Most young women feel embarrassed to consult a doctor if they experience complaints regarding the health of their reproductive organs and reproductive organ problems. By designing a 2D animated video about menstruation, the aim is to provide information and insight to young women. The method that will be used for data collection is by interviewing experts in the field and the method used in designing 2D animated videos is the MDLC (Multimedia Development Life Cycle) method which includes several stages, namely concept, design, data collection, creation, testing, and distribution. Then the final results of the animated video will be tested with experts in the field of female reproductive organs. In designing 2D animation, you will use the applications Adobe Illustrator, Adobe Audition, Adobe Animate, and Adobe After Effects. The result of this research is a 2D animated video entitled "What is Menstruation?" as a medium of information and insight.

Abstract

Facing the complex dynamics of freshman enrollment, the k-means clustering method was introduced as the main approach. The focus is on Abdurrab University, where various attributes of prospective students are investigated, including gender, parental education, parental income, hometown, province, age, and choice of study program. With the k-means clustering algorithm, the purpose of the study is to uncover the underlying patterns of preferences and characteristics of new student groups. The results of this study provide in-depth insight into the factors that influence the decision to admit new students in the campus environment of Abdurrab University. In this study Davies-Bouldin Index (DBI) was used as a method to determine the optimal number of clusters, the lowest DBI value was 1.5 which occurred in 8 clusters. This shows that 8 clusters is the optimal number of clusters for data that has been transformed and is ready for k-means clustering. After carrying out the clustering process with the K-Means method which involves the formation of 8 clusters, to show patterns and insights from the clustering results, there are two ways used in this study, first make a heatmap of the correlation of features displayed, information can be obtained about the relationship between variables. The correlation value ranges from -0.4 to 1.0 where positive values indicate a positive correlation and negative values indicate a negative correlation. A positive correlation means that if the value of one variable increases, then the value of the other variable also tends to increase. Conversely, negative correlation means that if the value of one variable increases, then the value of the other variable tends to decrease.

Abstract

Post traumatic stress disorder (PTSD) is a disorder experienced by someone due to surprising, scary, or dangerous events they had. Unfortunately, there is minimal knowledge about this disorder among Indonesian people so that many of them do not know what symptoms they have experienced and the effects from the disorder. The aim of this study is to build an expert system for early diagnose of this PTSD. Forward chaining method is utilized within the expert system to collect the symptoms experienced by users, processing them based on knowledge rules until a decision or conclusion achieved. The expert system was developed following the Expert System Development Life Cycle (ESDLC) and the built system usability level was measured by using the USE questionnaire. The system was then tested together with an expert that showed the agreement level of the system with the expert. From the Usability level measurement, the system got a score of 86.67% which show the system is useful for early diagnose of PTSD. Hopefully, this expert system could become a solution in giving ease of accessibility for people to get an early diagnose result of PTSD.
