“…One type of low-temperature sensor that can be used is an RTD-based temperature sensor (Fraden, 2010;Chowdhury and Bulbul, 2010;Blasdel et al, 2015). The economical RTD sensor has been developed by Toifur et al ( , 2020 and Khusnani et al (2019) with copper and nickel or Cu/Ni lm. The results of the study stated that the weakness of this sensor is the response time to slow temperatures for temperatures below -150°C while for temperatures above -150°C the temperature response is fast.…”

Increased export-import activities on fresh food commodities in the international market led to the idea of developing new technologies in the form of cryogenic freezers using liquid nitrogen (LN2). Along with the development of preservation methods using liquid nitrogen media, we need a tool that is able to detect changes in low temperatures in LN2 storage flasks that have economic value. Therefore the purpose of this research is to make a low-temperature sensor with copper and nickel material that has an economical price. The Cu/Ni film sensor is made with an electroplating method assisted by an external magnetic field of 200 G which is installed parallel to the deposition current. The Cu/Ni film was developed by varying the concentration of the electrolyte solution. The electrolyte solution used in the deposition process consisted of a mixture of H3BO3, NiSO4, NiCl2, and H2O. Furthermore, the Cu/Ni film that was made was tested on the LN2 medium to measure its sensitivity value in response to changes in temperature. The results showed that the Cu/Ni film sensor could detect changes in the low temperature in LN2. The results of data analysis showed that the curve relationship between voltage and temperature in the sample with the 2nd concentration (C2) had the highest relationship to influence each other between the voltage and temperature variables, and the sample had the highest sensitivity value compared to the others.

“…Arus pada proses elektroplating menggambarkan laju penumbuhan struktur lapisan Ni pada permukaan Cu. Penggunaan medan magnet (B) pada proses elektroplating membantu mensetabilkan arus (Khusnani et al, 2019 2015menyatakan bahwa peningkatan suhu larutan elektrolit terutama pada suhu tinggi dapat menyebabkan terjadinya pengurangan efisiensi arus. Dengan berkurangnya efisiensi arus maka jumlah ion-ion Ni yang terdeposit pada substrat juga menurun sehingga menyebabkan pembentukkan struktur lapisan yang tipis.…”

Tujuan penelitian ini adalah mengidentifikasi pengaruh variasi suhu larutan terhadap struktur lapisan yang terbentuk melalui metode elektroplating. Larutan elektrolit dibuat dengan campuran NiSO4, NiCL2,H3BO3, dan H2O. Elektroplating dilakukan selama 180 s dengan tegangan 4,5 V dan medan magnet 150 G pada arah sejajar permukaan katoda-anoda. Hasil penelitian menunjukkan suhu mempengaruhi ketebalan lapisan, arus listrik, jumlah zat yang terlepas dan terbentuk dan pH larutan. Lapisan paling tebal adalah sampel hasil deposisi pada suhu 40°C dengan ketebalan [(133,8 ± 0,9745)´ 10-5] cm pada pH 4,21. Kemudian yang paling tipis adalah sampel hasil deposisi pada suhu 60°C dengan ketebalan [(59,83 ± 0,6270) x 10-5] cm pada pH 4,18. Ketebalan lapisan yang terbentuk sebanding dengan jumlah zat terlarut dan jumlah arus yang mengalir selama pelapisan berlangsung. The purpose of this study is to identify the effect of temperature variations on the structure of the layers formed through the electroplating method. Electrolyte solution was made with mixture of NiSO4, NiCL2,H3BO3, and H2O. Electroplating was carried out for 180 s on the voltage of 4.5 V and magnetic field parallel to 150 G. The results showed temperature affects the thickness of the layer, electric current, the amount of released and formed substances and the pH of the solution. The thicknest of layer is according to the sample deposited at a temperature of 40°C with a thickness of [(133,8 ± 0,9745)x 10-5] cm at pH of 4.21. Then the thinnest one was according to the sample which was deposited at 60°C with a thickness of [(59,83 ± 0,6270) x 10-5] cm at pH of 4.18. The thickness of the layer is proportional to the amount of solute and the amount of current flowing during the coating. Keywords: Elektroplating, Flim Tipis, Cu/Ni, Suhu Larutan, Magnet Sejajar.
