Abstract

The spinal cord is a canal of the brain that runs from the neck to the coccyx. This nerve plays an important role in the process of sending signals from the brain to the rest of the body and vice versa. If this nerve is damaged, there will be interference with some body functions, such as the loss of the ability to move or feel things. Spinal cord patients should be treated immediately by a specialist doctor who deals with problems in neurological diseases. If treatment is not done immediately, the patient may need a longer recovery period. In addition, the possibility of worsening the condition or the appearance of complications will also be greater and some patients who experience diseases of the spinal nerves must undergo treatment or consultation with a doctor to follow up on the causes and symptoms they feel continuously. From the above problems, the authors want to create an application that can help patients to obtain information and make a temporary diagnosis through the application to be built. This application is useful to know the disease of the spinal cord in patients. From the research that has been done, the results of CF calculation with the highest value of 0.9857 or 98.57%, the system identifies that the patient is suffering from ischalgia.

Abstract

In Law no. 1 of 1974, article 7 paragraph (1) states that marriage is only permitted if the man has reached the age of 19 and the woman has reached the age of 16. Nationally, early marriage to the age of under 16 is 26.95%. In fact, based on the findings of Bappenas in 2008, it was stated that 34.5% of the 2,049,000 marriages in 2008 until now were child marriages which were increasing rapidly (Rifiani, 2011: 126). The influence of foreign culture is also one of the causes of the large number of underage marriages, foreign cultures which are very famous for freedom of dating, are the views of today's youth to have relations outside of legal marriage. Not only culture, information technology in the 4.0 era has greatly influenced the occurrence of underage marriages, adult video sites that are easily accessible via the internet. For this reason, the K-means clustering method is used as the right solution for the problem of underage marriage data by grouping the data based on age, gender, and occupation to get definite data, so that data grouping using the applicationmatlab andrapid miner can produce output from data mining that can be used in making decisions in the future.

Abstract

Soka crabs (soft cell crabs) are crabs in the molting phase or soft shell crabs. Crabs in this phase can be used as a whole so that this is an advantage of soka crabs (Sayuti, 2018). To get the maximum benefit, soka crab cultivation should not be done on the side or just a subsistence activity. Soka crabs can live in high stocking densities. Therefore, soka crab cultivation will provide more benefits if done intensively. But there are also problems that arise in soka crabs. The problem is the failure of this crab rearing activities. One of the causes of failure of this activity is due to disease factors. The emergence of disease disorders in crabs is a risk that must always be anticipated. Therefore, the authors will create an application system that can diagnose diseases that attack the soka crab. In the application, users only need to answer questions given by the application to be able to find out the disease that is attacking the soka crab. With the creation of this application people know about how to deal with the problem of disease in soka crabs, for that with this application the problem of lack of experts can be resolved. From the results of the analysis performed manually obtained the value of the certainty factor from the input of symptoms leading to Aeromonas spp is 73.1264%.
