Penerapan K-Optimal Pada Algoritma KNN Untuk Prediksi Kelulusan Tepat Waktu Mahasiswa Program Studi Teknik Informatika

Decision Making Systems (DSS) are the single most widely used computerized method today. Student satisfaction is determined by the quality that students want, so every university must ensure that this quality is available. The STIMIKOM Stella Maris Sumba Informatics Engineering Program can provide new information that was not previously known using data mining techniques that can be used to predict students' timely graduation. The research uses the k-Nearest Nieghbor method, which is a method for classifying objects based on training data that is closest to the object. Choosing the k value in the kNN algorithm is important because it will affect the performance of the kNN algorithm, therefore it is necessary to know what the k value is and the level of accuracy. The k-Fold Cross Validation method and Accuracy Test are used to determine the k-Optimal value. The result obtained is the value k=5 with an accuracy level of 80.00% which is designated as k-Optimal. The value k=5 is applied to the kNN algorithm to predict students' on-time graduation based on GPA up to semester 4

Sistem Monitoring Daya dan Arus Listrik Pada Pembakit Listrik Tenaga Bayu Berbasis Thingspeak

PLTB is a renewable energy solution that can reduce dependence on fossil fuels and reduce greenhouse gas emissions. To ensure operational efficiency and reliability, a monitoring system is needed. The monitoring system used in this paper consists of sensors integrated with Arduino to collect real-time data on wind speed, output voltage, current and operational conditions of Tingspeak-based turbines. The data collected by the sensors is sent to the Arduino Uno, which then processes the data for further analysis. Implementation of this Arduino Uno-based monitoring system also allows early detection of potential problems, so that preventive action can be taken to increase efficiency. The results of this research show that the factors that influence the performance of wind turbines are the voltage and current. So for this reason, a tool was created that can monitor and display the amount of voltage and current produced by the Wind Turbine. This tool uses the PZEM-004T sensor to measure current and voltage. The sensor measurement results are processed by the Arduino Nano R3 and then displayed on the LCD and ESP-01 chip to WiFi, then the data will be sent to the Thingspeack cloud server to display the current and voltag

PENERAPAN DATA MINING MENGGUNAKAN ALGORITMA APRIORI DALAM MEMPREDIKSI PENJUALAN KAIN TENUN SUMBA

Weaving is one of Indonesia's traditional fabric arts and culture which is produced in various regions throughout the archipelago (NTT, Kalimantan, Bali, Sulawesi, Lombok, Sumbawa, and others). Sumba woven fabric is a collection of activities that can define the work carried out by a system and change input into output that has added value for the user. Currently sales are only around Sumba Island. Meanwhile, the sales process is carried out by buyers coming directly to the shop, apart from that, woven fabrics are also sold in local markets and at cultural exhibitions. Therefore, an a priori algorithm approach was taken in association analysis to find candidate frequency itemsets to increase sales. Based on the sales results of woven fabric products in the kalaki kambe weaving group, the ones that sell the most can be found using an a priori algorithm, namely by looking at products that meet a minimum support of 2.4% and a minimum confidence of 50%. The most sold products are sarongs, wewewa woven fabric and loura woven fabric with the results obtained that sarongs, wewewa woven fabric and loura woven fabric with a support value of 0.300 or 30% and a trust value of 0.750 or 75%
