Auhi, Robbith Qosath Al and Dr. Eng. Panca Mudjirahardjo, S.T.,M.T. and Adharul Muttaqin, S.T.,M.T. (2022) Rancangan Bangun Sistem Rekayasa Suhu Pada Larutan Iodine Clock. Sarjana thesis, Universitas Brawijaya.
Abstract
Reaksi jam iodin (Iodine clock) adalah reaksi kimia yang dapat mengajarkan prinsip-prinsip dasar pengendalian kimia. Reaksi iodine clock adalah ketika dua larutan bening yang dicampurkan, menghasilkan larutan bening lainnya. Setelah beberapa saat, larutan tersebut akan seketika berubah warna menjadi biru gelap. Waktu reaksi Iodine clock untuk berubah warna dapat digunakan sebagi timer untuk mekanisme pemberhentian pada prototipe mobil bertenaga kimia. Waktu reaksi laruran Iodine untuk berubah warna menjadi biru gelap dipengaruhi oleh suhu, komsentrasi, dan katalis. Dengan asumsi konsentrasi dan katalis tetap, maka semakin tinggi suhu larutan semakin cepat iodine clock untuk berubah warna dan sebaliknya. Tim Chem E Car Universitas Brawijaya menggunakan iodine clock sebgai mekanisme pemberhentian pada prototipe mobil bertenaga kimianya. Pada penggunaan iodie clock sebagai mekanisme pemberhentian, tim Chem E Car Universitas Brawijaya belum memperhatikan faktor suhu yang berpengaruh pada lama waktu reaksi iodine clock. Tim Chem E Car Universitas Brawijaya melakukan latihan (trial) pada ruangan tertutup sementara perlombaan berlangsung di lapangan terbuka, Suhu dilapangan terbuka berbeda dan fluktuatif dibandingkan disuhu ruang tertutup, sehingga waktu reaksi iodine clock pada saat perlombaan berbeda dengan waktu reaksi iodine clock pada saat trial.
English Abstract
Iodine clock reaction (Iodine clock) is a chemical reaction that can teach the basic principles of chemical control. The iodine clock reaction is when two clear solutions are mixed, producing another clear solution. After a while, the solution will suddenly change color to dark blue. The reaction time of the Iodine clock to change color can be used as a timer for the stopping mechanism in chemical-powered car prototypes. Iodine solution reaction time to change color to dark blue is influenced by temperature, concentration, and catalyst. Assuming the concentration and catalyst are constant, the higher the temperature of the solution, the faster the iodine clock changes color and vice versa. The Brawijaya University Chem E Car team used iodine clock as a stopping mechanism for their chemical-powered car prototype. In using iodie clock as a stopping mechanism, the Brawijaya University Chem E Car team has not paid attention to the temperature factor that affects the reaction time of iodine clock. The Brawijaya University Chem E Car team carried out a trial (trial) in a closed room while the competition took place in an open field. The temperature in the open field was different and fluctuated compared to the closed room temperature, so the reaction time of the iodine clock during the race was different from the reaction time of the iodine clock during the trial.
