Abstract

This study aims to make a temperature sensor using coil wire with an indicator in the form of light intensity and to test the sensitivity of iron, copper, and nichrome wires in responding to changes in temperature. The temperature sensor unit consists of a coil of 250 turns, connected in series with a 3V/32W DC lamp and a 3 volt constant voltage source. As a medium, a room illuminated by a 100 watt lamp was used, where the lamp voltage is adjusted from 50 V to 150 V via slide regulator to produce a medium temperature from 30°C to 100°C, while for the indicator lamps, the light intensity of the lamp is measured with a luxmeter UT383. The results showed that there was a significant relationship between changes in medium temperature to light intensity for copper and iron coils while the nichrome coil is not. From the linear regression on temperature and light intensity data, the sensor sensitivity of copper and iron wire coils is (1.34 ±0.06) lux/°C and (7.33 ± 0.43) lux/°C, respectively. From these values can be known that the temperature sensor of the iron coil is more sensitive than copper, but the copper coil is more precise in indicating temperature than the iron coil. From this research, a temperature sensor unit made of copper and iron coils has been successfully made to measure the temperature of the medium from 30°C to 100°C using a light intensity indicator.

Abstract

Pada dasarnya, peserta didik kelas X-H SMA Negeri 1 Purworejo tergolong kelas yang aktif. Terlihat pada saat observasi pembelajaran, beberapa peserta didik berani menjawab pertanyaan dari guru. Namun demikian, berdasarkan hasil observasi dan profilling peserta didik ditemukan adanya masalah atau kurangnya keterlibatan peserta didik dalam pembelajaran. Berdasarkan identifikasi masalah yang ada di kelas X-H SMA Negeri 1 Purworejo, maka diambil batasan masalahnya yaitu rendahnya sikap ilmiah peserta didik pada saat observasi pembelajaran. Penelitian ini bertujuan untuk meningkatkan kemampuan sikap ilmiah peserta didik menggunakan Problem Based Learning (PBL) berbantuan media interaktif Youtube. Penelitian ini merupakan penelitian tindakan kelas dengan subjek kelas X-H yang terdiri dari 35 peserta didik. Teknik pengumpulan data menggunakan teknik non tes berupa lembar observasi dan dokumentasi. Teknik analsis data menggunakan analisis data kuantitatif dan kualitatif. Teknik analisis data kuantitatif menggunakan rata-rata (dalam persentase) hasil lembar observasi kemampuan sikap ilmiah peserta didik. Sedangkan teknik analisis data kualitatif menggunakan deskriptif kualitatif berdasarkan dokumentasi dan lembar keterlaksanaan model PBL. Hasil penelitian ini menunjukkan bahwa penerapan PBL berbantuan video interaktif Youtube mampu meningkatkan sikap ilmiah peserta didik pada materi Pemanasan Global. Hasil analisis rata-rata sikap ilmiah pada Siklus I yaitu 76% dan pada Siklus II yaitu 88% (mencapai target penelitian 80%).
