Abstract

Every living thing needs food to live, grow and reproduce. Food is a basic need that is needed by humans as a source of energy to carry out activities in daily life. By eating nutritIoUs food can bring a person into a healthy diet. An unhealthy diet can cause a person to create diseases such as malnutrition or even death. It is important to regulate the amount of food consumption to maintain and maintain a healthy body, so we need a system that can estimate the food consumed. To estimate the weight of the food that has been consumed by someone, an image of the food is needed before and before consumption. In this study the data used is secondary data in the form of food images in the tray box which opens 31 images consisting of 124 compartment images. The improvement K-Means method was chosen for segmenting food images on the tray box. With the application of this method, it is expected to provide results with a small error rate and have good accuracy in the estimation of food waste in the tray box. the results based on the evaluation of the results of the highest average accuracy of segmentation results of 82% with the RMSE estimation of the smallest food waste weight achievement of 2.19. The test results show that the clustering method with the K-Means improvement algorithm can be used to estimate the weight of food images.

Abstract

Publication articles are contained in journals published by universities or colleges and many are also published by institutions providing national and international journals. Journal of Information Technology and Computer Science (JTIIK) is one of several journals that accept publication articles based on the principle of open dissemination of publications to advance science, especially in the IT field. JTIIK itself is managed by the Faculty of Computer Science, Universitas Brawijaya and started publishing journals in 2014. At JTIIK, the author categorises Publication Articles manually by the author when submitting the manuscript or by the editor during the review and editing process. Therefore, there is a need for automatic grouping of Published Articles documents. The focus of this study is to determine the application of the Improved K-Nearest Neighbor method in the classification of the title of JTIIK Publication Articles. This research was carried out in several processes: Preprocessing, Word Weighting, Feature Selection, Cosine Similarity, and classification with Improved K-Nearest Neighbor. Testing the value of k and using feature selection with K-Fold Cross Validation, the results of changing the value of k and the application of feature selection affect the evaluation results of Improved K-Nearest Neighbor, with a value of k = 5 and feature selection with a threshold DF = 1 as the optimal parameter. Tests with all data resulted in Accuracy of 90.00%, F-measure of 85.78%, Recall of 87.58% and Precision of 84.40%.

Abstract

Food is the main source of energy for humans. Sufficient energy can support the performance of daily activities, especially for athletes, such as endurance athletes. Endurance athlete sports activities have a long enough duration so they require a lot of energy. Therefore, the selection of food components for athletes every day can be one of the supporting factors in providing their best performance. The current research provides a solution in the form of recommendations for food ingredients in 1 day for endurance athletes by considering their nutritional needs using a hybrid genetic algorithm and simulated annealing method. The food ingredients component has a total of 125 data, consisting of staple foods, vegetables, animals, and complementary foods that have carbohydrates, proteins and fats in them. Recommendations are given in the form of chromosomal representation of 14 food ingredients consisting of 3 food packages. Based on the testing process, the optimal parameter has a population of 1000, 2000 generations, the combination of Cr = 0.1 and Mr = 0.9, T0 = 0.7, T = 0.5, alpha value = 0.2. The results of this study resulted in recommendations for food components by considering the nutritional needs of athletes within the tolerance limit of nutritional content, which is ±10% for endurance sports athletes.

Abstract

The Covid-19 pandemic is a new virus that attacks the body's immunity, various steps and efforts have been made to prevent transmission of the virus. The problems experienced are that the spread of Covid-19 is very fast, lack of exercise and high stress levels can weaken the body's immunity, and a poor diet can worsen the body's immunity. And there is no computer-based system to determine the combination of food ingredients as a form of early prevention of contracting Covid-19. The Ministry of Health provides an appeal for the fulfillment of balanced nutrition to increase body immunity so that it can reduce the risk of chronic diseases and infections with optimal nutrition to build or improve the body's immunity to work properly. In solving optimization problems, genetic algorithms can be used, which are effective in solving optimization problems with chromosomal variations obtained through the basis of biological evolution with a wide search space, so that they are not trapped in the local optimum. This study provides recommendations for food ingredients that can be consumed for 2 days and in consultation with nutritionists. Based on the test, the most optimal results are obtained with a combination of the values ​​of cr 0,3 and mr 0,7 with an average fitness value of 0,848, a population size of 160 with an average fitness value of 0,917, and the number of generations 241 with an average fitness value of 1,076. And can save expenses by 33% in a day with an average cost of Rp26.800 for men and 42% for women with an average cost of Rp23.350.

Abstract

Distribution is one thing that is very important so that a product can be delivered to customers / consumers. The job of a salesman is to visit the store or customer one day before the goods are shipped to offer the product and record the ordered goods. Factors that must be considered in the process are the time and costs required to be as minimal as possible. One aspect that can influence these two factors is the optimal travel route. In this study, the problem that we will try to solve is the optimization of product distribution routes at PT Indomarco Adi Prima (Stock Point Nganjuk) which has several points to be visited by more than one salesman one day before the distribution of goods. There are several processes to solve these problems, namely input data in the form of latitude and longitude data, then the data will be divided into several clusters according to the number of salesmen in the company, then each cluster will look for the shortest route for 5 working days and the end result is all the shortest routes from each cluster the total distance traveled will be calculated. Based on the results of tests that have been carried out using latitude and longitude data obtained from PT Indomarco Adi Prima (Stock Point Nganjuk), the most optimal route results with a total distance of 259.722337 km with a fitness of 0.385026. The most optimal parameter is when the population size is 1600, the number of generations is 800 with a combination of crossover rate (cr) 0.4 and mutation rate (mr) 0.6.

Abstract

Email is one of the digital means of communication that has existed since the beginning of internet development and is currently being used popularly. Email is an important means of communication, including for PT Green Air Pacific Surabaya. PT Green Air Pacific Company is a private company engaged in logistics. Because it is engaged in logistics, most of its operations use email as a medium of communication and information. In a day messages received via email can reach 700 messages. Incoming email messages are also not all-important for company productivity, so the increasing number of incoming email messages can actually make it difficult to process company email messages. Based on these problems in this study, an email classification system was made based on its usefulness and importance where the method used was the K-Nearest Neighbor (KNN) classification method. The results of the email classification system based on its importance using the KNN method (a case study of PT Green Air Pacific) show that the highest F-Measure is located at k= 3 and k= 4, which is 98.734, and with the K-Fold Cross Validation data validation method, the F results are obtained.-The highest measure is 100%.

Abstract

Carelessness in driving can result in accidents that can harm yourself and others. To reduce losses caused by accidents, one can use insurance services. However, there are still many Indonesians who have not used insurance services due to high premiums. From these problems, a solution is needed to recommend someone to take insurance from the level of driving experience. One of the methods adopted from this research is to improve k-means with centroid initialization based on sum square error and k-nearest neighbor. The data used in this research are 600 data safe drivers, consisting of numeric data and categories. The recommendation process begins with clustering using k-means with the initialization of centroid sum square error which produces an average of 1000 iterations, which is 1660.64. From the SSE process, the optimum centroid was obtained and continued with the k-means process with k-prototype. The use of k-prototype is due to the data consisting of numeric and categorical data. After the clustering process, the distance between the tes data and the centroid is calculated to find the closest cluster. Furthermore, the classification process is carried out on the nearest cluster in order to make the classification process more efficient. The classification process uses KNN which aims to determine whether data is included in the recommendation category and not. From the tesing process the improve k-means method produces the highest average value of 72.83% accuracy, while the KNN method produces an average accuracy value of 47.5%. The results of these calculations use the value of k = 3 and k-fold on cross validation of 5.
