Abstract

The increasing need for food is not in line with the clearing of agricultural land for food crops. So that the effort to increase the productivity of agricultural products is by applying precision agriculture. However, in reality, precision agriculture is difficult to apply to conventional processes, where farmers come to the farm, collect data, then carry out maintenance. This method will make production results not optimal because maintenance is not done accurately. This study introduces a monitoring system for environmental conditions based on the Internet of Things (IoT) for agricultural land, where trials are carried out in a greenhouse. The system that has been developed consists of several sensors designed to collect information related to agricultural environmental conditions, including DHT22 sensor (temperature and humidity), DS18B20 sensor (soil temperature), soil moisture sensor (moisture content in the soil), and BH1750 sensor (light intensity). Based on the Message Queuing Telemetry Transport (MQTT) protocol, the data is sent to a gateway (Raspberry Pi) and a local server via a wireless network to be stored in a database. By using the Node-RED Dashboard, the received sensor data is then displayed on the browser every time the sensor sends data. In addition, the local server also publishes sensor data to the public MQTT broker so that sensor data can be accessed through the MQTT Dashboard application on a smartphone. The results of testing for 25 days of the system running obtained an average success of the system in storing data of 99.64%.

Abstract

Klasifikasi merupakan masalah penting dalam dunia ilmu data, dimana model dibangun untuk memprediksi label atau kelas pada suatu data berdasarkan fitur-fitur yang dimilikinya. Pembangunan model dan penggunaannya untuk melakukan klasifikasi adalah pekerjaan utama dalam klasifikasi. Berbagai metode klasifikasi telah dikembangkan, termasuk Learning Vector Quantization (LVQ) dan Diskriminan Fisher. Penelitian ini bertujan untuk membandingkan metode klasifikasi LVQ dan Diskriminan Fisher pada data bunga iris untuk menentukan metode yang lebih efektif dan efisien dalam melakukan klasifikasi. Hasil penelitian menunjukkan bahwa kedua metode mampu melakukan klasifikasi dengan akurasi yang cukup tinggi. Namun, terdapat perbedaan dalam kinerja kedua metode tersebut. Metode LVQ menghasilkan akurasi tertinggi sebesar 96.29% dengan waktu proses 4.56 second, sedangkan metode Diskriminan Fisher menghasilkan akurasi sebesar 100% dengan waktu proses 0.1 second. Hal ini menunjukkan bahwa metode Diskriminan Fisher lebih unggul dalam melakukan klasifikasi pada data bunga iris. Selain itu, hasil pengukuran waktu eksekusi menunjukkan bahwa metode Diskriminan Fisher lebih cepat dalam melakukan klasifikasi dibandingkan dengan metode LVQ.
