Abstract
Indonesia turut serta bersama PBB menyukseskan komitmen global dalam rangka Tujuan Pembangunan Berkelanjutan atau Sustainable Development Goals (SDGs). Salah satunya dengan mengganti bahan bakar fosil dengan energi terbarukan untuk diubah menjadi energi listrik. Oleh karena itu, diperlukan perangkat penyimpanan energi yang memadai. Superkapasitor hybrid merupakan salah satu jenis penyimpanan energi yang sistem kerjanya gabungan dari EDLCs dan pseudocapacitor. Pada penelitian ini dilakukan sintesis elektroda Superkapasitor Hybrid untuk menganalisis pengaruh temperatur hidrotermal terhadap struktur, morfologi, dan sifat kapasitif komposit N-Doped rGO/CuCr2O4. Elektroda dibuat dengan mengkompositkan N-rGO dengan CuCr2O4 untuk mendapatkan sifat terbaik dari kedua jenis superkapasitor. Metode yang digunakan adalah hidrotermal dengan variasi temperatur yaitu 120º, 140º, dan 160º C. Karakterisasi SEM-EDX, XRD, dan FTIR dilakukan untuk menganalisis struktur dan morfologi komposit. Sedangkan pengujian CV dan EIS dilakukan untuk mengukur nilai kapasitansi dan konduktivitas dari N-Doped rGO/CuCr2O4. Berdasarkan hasil pengujian XRD, FTIR, dan SEM-EDX penambahan temperatur membuat nilai dspacing semakin besar yang mengindikasikan semakin banyak atom Nitrogen yang tersubtitusi. Hal tersebut diperkuat dengan hasil EDX bahwa sampel dengan temperatur hidrotermal 160°C memiliki presentase Nitrogen terbesar. Nitrogen berperan penting dalam meningkatkan konduktivitas dari material. Dari hasil FTIR juga terdapat ikatan antara C dan N. Sedangkan dari hasil pengujian CV, nilai kapasitansi terbesar dimiliki sampel dengan temperatur hidrotermal 160°C yaitu sebesar 221.59 F/g. Hal itu sejalan dengan hasil pengujian EIS yang memiliki nilai konduktivitas terbesar yaitu 549 S/m. Menandakan sampel tersebut memiliki konduktivitas yang paling baik.

Indonesia has participated with the United Nations in the success of global commitments in the context of the Sustainable Development Goals (SDGs). One of them by replacing fossil fuels with renewable energy to be converted into electrical energy. Therefore, adequate energy storage devices are required. Hybrid supercapacitor is a type of energy storage whose working system is a combination of EDLCs and pseudocapacitors. In this study, hybrid supercapacitor electrodes were synthesized to analyze the effect of hydrothermal temperature on the structure, morphology, and capacitive properties of N-Doped rGO/CuCr2O4 composites. The electrodes were made by composited N-rGO with CuCr2O4 to obtain the best properties of both types of supercapacitors. The method used is hydrothermal with temperature variations of 120º, 140º, and 160º C. Characterization of SEM-EDX, XRD, and FTIR was carried out to analyze the structure and morphology of the composite. While the CV and EIS tests were carried out to determine the capacitance and conductivity values of N-Doped rGO/CuCr2O4. Based on the results of XRD, FTIR, and SEM-EDX testing, the addition of temperature makes the dspacing value greater which indicates more nitrogen atoms are substituted. This is reinforced by the results of EDX that the sample with a hydrothermal temperature of 160°C has the largest percentage of Nitrogen. Nitrogen plays an important role in increasing the conductivity of the material. From the results of FTIR there is also a bond between C and N. Meanwhile, from the results of the CV test, the largest capacitance value is owned by the sample with a hydrothermal temperature of 160°C, which is 221.59 F/g. This is in line with the results of the EIS test which has the highest conductivity value of 549 S/m. Indicates that the sample has the best conductivity.
