Abstract

Intermittent credit is one of the problems or risks that are often faced by some auto loan service providers. The problem stems from the debtor's behavior, namely not paying the installments on time. In determining the smoothness of credit payments depends on the analysis of debtor data, but analyzing for large amounts of data can take up more time. This study uses the Information Gain feature selection and the K-Nearest Neighbor algorithm to overcome the problem of effectiveness and determine the accuracy of the classification level of the smoothness of auto loan payments so as to determine the effect of feature selection. Information Gain feature selection which is used to reduce feature dimensions so that relevant features can be obtained. The selected features are then processed for classification using the K-Nearest Neighbor algorithm. Based on testing from this study, the highest accuracy obtained is 94.44% when testing with a balanced class distribution using the number of features 3 and the value of K = 4 while the lowest accuracy is obtained at 33.33% using the number of features 10 with a value of K = 5 when testing with uneven class distribution. Features that produce the highest accuracy are jobs, income and price on the road (OTR). The three features are features with the largest order of gain values and have a gain value of more than 0.1.

Abstract

Oranges contain vitamin C and a lot of mineral content. The public will definitely choose an orange fruit whose skin color is orange or the condition is ripe. Therefore, farmers must harvest citrus fruit when the conditions are ripe or when the color of the skin turns orange. In the area of ​​agriculture today there are those who implement modern agriculture. The use of technology applied to agriculture is the use of robots. Currently in Indonesia there is no robot that automatically harvests mature oranges in the garden by detecting which ones are already ripe in the garden and then picking them. The harvest process also requires a counter function of ripe oranges in the garden which can be detected to find out the number of ripe oranges found in the garden. From the problems above, the research conducted by this writer will focus on the detection of mature oranges in the garden and the calculation of mature oranges detected using digital image processing. This system will take pictures of oranges found in the garden. The process of detecting ripe oranges uses the Hue, Saturation and Chrominance-Red color space, whereas for the calculation of ripe oranges detected using a watershed algorithm. In testing the system in the process of calculating ripe oranges using watershed algorithm obtained an accuracy rate of 82.14% with an average computing time of 2652 ms for one calculation process.

Abstract

In 2016, cardiovascular disease was the number one cause of death in the world. It was happened because cardiovascular disease was often detected late. The application of Internet of Things (IoT) in electrocardiogram (ECG) monitoring is considered as a solution to that problem. At this moment, an ECG monitoring system has been developed using IoT architecture. That system consists of ECG sensor nodes that use WiFi to transmit ECG data to the data storage on the cloud. However, WiFi is considered unsuitable to be used in IoT applications because of its large frame overhead and high power consumption. Therefore, a mechanism for transmitting ECG data based on LoRa technology, which is considered suitable because of its small frame overhead and low power consumption, is designed. This research produced a mechanism where sensor nodes are able to record and send ECG data to the LoRa gateway and LoRa gateway is able to forward received ECG data to the application on the cloud. However, the applied ECG data transmission mechanism in this research resulted 25,5 seconds end-to-end delay. So, it didn't fulfill the requirement in ECG data transmission for non-critical monitoring uses, the unfulfilled requirement is 4 seconds maximum delay.

Abstract

Food is one of the needs in primary needs which is very important for humans. These needs must be met every day, but the human tendency for food needs changes with the times. Society in general will choose fast food that is ready to be served rather than choosing traditional food. In this day and age, most people tend to capture the moment when they want to enjoy a food that will be consumed. Taking pictures (photos) is one way, from which the images are obtained an image on food. The image will display several different colors, so the color will be a feature that can be used for extraction. One method used to extract color features in images is Color Moment. This feature will produce three main values namely mean, standard deviation, and skewness. In addition, this feature together with the K-Nearest Neighbor (K-NN) algorithm will classify the extracted colors based on training data taken as many as k values. In this study, there are 29 Indonesian traditional cake objects that will be used, where the test scenario is divided into 29 classes, 8 classes, 5 classes, and 3 classes. By using the K-NN method and the Color Moment feature, the highest evaluation value obtained is 60% for the test scenario of 3 classes.
