Abstract
Saat ini kebakaran lahan sering terjadi di Indonesia. Pencegahan dapat dilakukan dengan cara mendeteksi titik panas (hotspot) sebelum terjadinya kebakaran. Titik panas adalah daerah yang memiliki suhu permukaan relatif lebih tinggi dibandingkan daerah di sekitarnya. Pada penelitian ini telah dirancang suatu sistem pencegahan yang dapat memetakan suhu suatu permukaan area atau lahan. Pengukur suhu berupa sensor inframerah thermopile akan mengukur intensitas cahaya inframerah yang terpancar dari suatu titik / objek tanpa kontak. Intensitas cahaya inframerah ini proporsional terhadap suhu objek tersebut. Tegangan keluaran dari sensor thermopile dikuatkan oleh rangkaian pengondisi sinyal dan kemudian dibaca Analog to Digital Converter pada mikrokontroler Arduino Nano. Sistem pemindai yang menggunakan motor servo dan motor stepper, digunakan untuk mengubah arah titik pengukuran suhu beberapa titik dalam area lahan sehingga suhu suatu area di sekitar sistem dapat dipetakan. Data-data suhu pada area tersebut kemudian divisualisasikan pada perangkat lunak pemetaan komputer yang dirancang menggunakan IDE Microsoft Visual Studio. Sistem pengukur suhu berdasarkan sensor inframerah thermopile dapat mengukur suhu tanpa kontak dengan rerata kesalahan sebesar 6,4% pada rentang pengukuran suhu 37 ºC s.d. 170 ºC. Sistem pemindai yang menggunakan motor servo dan stepper dapat mengubah arah titik pengukuran sehingga dapat mengukur dan menggambarkan profil suhu permukaannya dengan perangkat lunak pemetaan.

Currently landfires are often occur in Indonesia. Prevention can be done by detecting hotspots before the case of fire. Hotspots are areas that have relatively higher surface temperatures than the surrounding area. In this research has designed a prevention system that can map the temperature of a surface area or land. The thermopile infrared sensor will measure the intensity of the infrared light emitted from a point / object without contact. The intensity of infrared light is proportional to the temperature of the object. The output voltage of the thermopile sensor is amplified by the signal conditioning circuit and then is read by Analog to Digital Converter on the Arduino Nano microcontroller. Scanner system that use servo and stepper motor, are used to change the direction of the point of temperature measurement of multiple points within the area of the land so that the temperature of an area around the system can be mapped. Temperature data in the area is then visualized in computer mapping software that is designed using Microsoft Visual Studio IDE. The temperature measuring system based on the thermopile infrared sensor can measure the temperature without contact with a mean error of 6.4% over a measurement range of 37 ºC - 170ºC. Scanner system that use servo and stepper motors can change the direction of measurement points, so that is able to measure and describe their surface temperature profiles with mapping software.
