The development of technology and information makes it easier for humans to exchange information that is not limited to distance and time. Advances in technology make it easy for people to get information instantly even though they are separated by great distances. However, this convenience is also accompanied by threats to irresponsible elements. who can access the contents of the information. Security of an information message is very necessary so that the message only reaches the intended person and other people who are not entitled to the contents of the information cannot access it. This research aims to create a text message security system using an algorithm Vigenere Cipher cryptography which aims to make the contents of the message only understandable by the recipient of the message which can increase confidentiality in exchanging information. The test results of this system can encrypt messages into ciphertext and perform decryption so that the message returns to the original message. yes

Autism is a developmental disorder that affects the normal functioning of the brain, thereby affecting a child's communication and social interaction abilities. This disorder poses a problem for children in communicating and forming relationships with their environment. As the number of individuals with autism increases, public awareness of autism remains very low. Additionally, most psychologists or psychiatrists are located in major cities, limiting access for rural communities. This leads to many parents struggling to obtain information about autism symptoms. The research method used is the naïve Bayes method, it can be drawn from the system is that it will generate the maximum score despite any disturbances in the provided data. The results of this research align with expert knowledge, suggesting that it can be relied upon to accurately diagnose autism based on the symptoms experienced by individuals. The aim of this study is to build an expert system that can provide information and solutions to parents regarding autism disorders based on their knowledge of the symptoms they experience, enabling users to diagnose autism in their children early on without incurring costs.

Currently, facial care is highly desired by society, especially for women in this world. Problems with the face can be caused by unsuitable care products used because they don't know the problems with each individual face. One of the treatments that can be done is at the Putri Ms Glow store, where we can ask for solutions or good consultations in dealing with problems on each patient's face. Given these problems, it is necessary to create or design a web-based Decision Support System using the AHP and SAW methods. The existence of the AHP and SAW methods can be expressed as a comparison that can make it easier to calculate a ranking weight between alternatives. In order to make it easier for patients to carry out consultations or treatment, the design of this web application was carried out using a system that was designed or a system that is currently running, where data is obtained from the results of observations or interviews in order to determine criteria and alternatives in making decisions for Putri Ms Glow. After the data is collected, weighting calculations are carried out from AHP and after that they are ranked using SAW to determine which patients are prioritized first. Based on the results of research and calculations that have been tested using the AHP method, it helps weight alternatives and criteria with a weight scale of 1-9 , after the weighting was carried out, the ranking was carried out using the SAW method to get the final score, rank 1 was obtained by Resti with a final score of 1.0067 and rank 15 was obtained by Suci with a final score of 0.5633. The before, it is the priority for Resti to get treatment first.

Palm oil is one of the important commodities in Indonesia today and has quite promising development prospects, Pt. Toton Usaha Mandiri is an oil palm plantation, oil palm plantations are very profitabel so many forests are being converted into oil palm plantations, even though oil palm is very profitabel, it is very difficult to determine the amount of palm oil production in the future, therefore the author will predict the amount of palm oil production going forward with factors that influence palm oil production including demand, supply, production efficiency and variables related to palm oil production such as total income, total supply and total demand needed to achieve good production levels. One way to predict the rate of palm oil production is to use the C4.5 method. The C4.5 algorithm is an algorithm that can form a decision tree, where the decision tree will then produce new knowledge. In the target attribute, the amount of palm oil production is Satisfactory and Not Satisfactory. The analysis used is the C4.5 Algorithm which has a data sample of 54 data from 2019 to 2023 June. By processing the data using the Rapid Miner application, the system accuracy value was 96.30% the unsatisfactory prediction was 16 and the satisfactory prediction was 36 with a precision value of 94.12% and a recall value of 97.30%.
