Abstract

Suhu permukaan bumi terasa semakin panas dari hari ke hari. Salah satu penyebab yaitu terjadinya efek rumah kaca. Efek rumah kaca merupakan fenomena terperangkapnya radiasi sinar matahari di atmosfer bumi. Sinar inframerah merupakan salah satu bagian dari sinar matahari yang terperangkap di atmosfer bumi. Jika kulit manusia terpapar sinar inframerah secara berlebihan dapat menyebabkan penyakit kanker kulit dan kulit terbakar. Sehingga, terbentuk piranti untuk menganalisis daya serap spektrum inframerah. Sensor fotodioda berfungsi sebagai pendeteksi daya serap pada spektrum inframerah. Rancang bangun piranti ini terdiri atas sensor fotodioda, LED inframerah, kaca bening, plastik mika berwarna, power supply, PCB, Arduino Uno R3, dan Software Arduino Ide. Sistem piranti ini dapat bekerja dari tegangan keluaran sensor yang dibaca oleh software Arduino Ide dengan mengubah sinyal analog menjadi sinyal digital oleh ADC. Berdasarkan hasil penelitian dan analisis telah terbentuk rancang bangun yang dapat diimplementasikan untuk mendeteksi daya serap spektrum inframerah. Kaca bening dengan jarak 2 cm merupakan sampel yang memiliki daya serap paling tinggi pada spektrum inframerah (29%). Pada penelitian ini dapat dilihat bahwa nilai tegangan akan menurun ketika jarak antara LED inframerah dengan sensor fotodioda semakin jauh

Earth's surface temperature getting hotter by the day. One of the causes is the greenhouse effect. The greenhouse effect is the phenomenon of trapping solar radiation from the earth's atmosphere. Infrared rays are part of the sun's rays trapped in the Earth's atmosphere. If human skin is exposed to excessive infrared rays can cause skin cancer and sunburn. Thus, a tool is formed for analysed the absorption of the infrared spectrum. The photodiode sensor functions as a detector for absorption in the infrared spectrum. The design of this device consists of a photodiode sensor, LED infrared, clear glass and coloured mica plastic, power supply, PCB, Arduino Uno R3, and Arduino Ide software. This device system can work from the sensor output voltage which is read by the Arduino Ide software by converting analogue signals into digital signals by the ADC. Based on the results of research and analysis, a design has been formed that can be implemented to detect the absorption of the infrared spectrum. Clear glass with a distance of 2 cm is the sample that has the highest absorption in the infrared spectrum (29%). In this study, it can be seen that the voltage value will decrease when the distance between the infrared LED and the photodiode sensor is getting further away.
