The solution offered to partners' problems in managing tuna production is an effort to increase partners' income so that they can produce better tuna in quality and quantity. Second, with modern technology in the production of shredded tuna by providing better packaging so that consumers are more interested, the abon processing business can create independent economic income. Problems faced by partners include the lack of processing facilities that meet industrial standards, the need for good business management, and ineffective marketing by partners. The results of this service provide solutions for standard ergonomics that are used, and the processing site must be really comfortable to use and sterile as well as good and sterile tuna processing methods, provide material on business management, including management procedures starting from the process of providing raw materials, processing production and financial management by recording cash inflows and outflows. Furthermore, there is marketing in the sale of shredded tuna by using marketing strategies such as WhatsApp and the web to reach partners based on social media. The results of this service are: the creation of an ideal shredded tuna fish production business; second management (governance) of shredded tuna production, processed fish that meets standards, modern marketing processes, and proper targeted shredded tuna processing, as well as increasing partner income.

Advances in information technology are one of the potentials that are useful in improving learning methods. Currently, content and media that are directly related to science can be more interactive and interesting for students to trigger interest in learning. Internet technology can remove limitations in various information and provide learning materials more easily. However, there were still many teachers who focus on traditional and oral teaching approaches, even using less learning media. The use of learning media is very important for the teaching and learning process and the role of the media can be used in every discipline to enhance learning in the classroom and outside the classroom. The problems that have arisen so far indicate that teaching uses abstract concepts were not easy to be presented in both verbal and visual forms. Another goal was that visual media can be more easily understood and be easily accessed by students than text media. Therefore, another goal of this service was to train educators at SMA 1 Lhoksemawe to become more familiar with the latest learning media to be applied in the teaching and learning process. From the results of this communty service it is expected that teachers can use several multimedia in learning which is a combination of text, graphics, animation, images, video and audio which help students understand the material more easily.

Cardiovascular disease is a problem in the blood vessels that do not run smoothly into the heart. This is fatal in patients with a history of heart disease. This problem often occurs in the flow of blood pumps into the heart. The problem examined in this study is how to complete the level of accuracy of each data set and the reduction of each attribute in heart disease. The purpose of this study is to analyze heart disease and classify heart disease using the chi-square and K-Nearest Neighbor algorithms. The results of the study with patient age 57, gender LK, cp 3, trestbps 200, chol 564, fbs 1, restecg 2, thalach 202, oldpeak 6.2, slope 2, ca 4, and the value of thal 3 for the target is there is disease heart 0 or 1 is detected without heart disease when the max-min data is normalized. while to measure the performance of the algorithm with the value of the confusion matrix with the actual class value of 1, prediction class 1 value 44, actual class 0 and prediction class value 6. while the actual class value 0-1, prediction class 1 value 5 and 0-0 value 36. the final stage value of the accuracy measure is 0.87912, the recall value is 0.89797 and the precision value is 0.85714. The implication of the application of the test has an optimal test, the accuracy value with data K = 303 then it can be concluded that based on the test the calculation of the KNN model obtained an accuracy of 91%
