Abstract

Supercapacitors are promising energy storage devices in future energy technology. In this research, the primary and applied aspects of supercapacitors are developed. Various techniques have been developed specifically to estimate specific capacitances. Various attempts have been made in the literature to increase the specific capacitance value of the electrode materials. Electrode materials with unique structural and electrochemical properties, such as high capacity and cyclic stability, exhibit good supercapacitor performance. Many new electrode materials have been developed to play an essential role in capacitance behavior. This research focuses on the highly efficient application of nanostructured electrode materials such as nanoporous carbon and metal oxide CuO for supercapacitors. Nanopore carbon is made from coconut shell, which is synthesized using a simple heating method. Next, carbon nanopore and CuO nanoparticle composites were carried out with composition variations of 0.5,10,15, and 20% of the total weight. The results of cyclic voltammetry, electrochemical impedance spectroscopy, and charge-discharge tests, maximum results were obtained on a composition of 5% CuO nanoparticles with a capacitance of 280 F/gr and a conductivity of 1.14 X 10-2 S/cm. This result is due to an increase in the surface area between the pore surfaces, so more ions are trapped, causing the filling process to take place quickly.

Abstract

Students have unique and diverse characteristics. One of the strategies used to facilitate student diversity is through differentiation learning. The research aims to explain the findings or problems of case studies in learning Physics at SMAN 8 Yogyakarta and explain the differentiated learning to solve these problems. The research approach used is qualitative with the case study method. Data collection techniques use non-test techniques using documentation and observation. Based on the results, differentiated learning can facilitate the needs of students who have diverse learning modalities, including students with visual and kinesthetic learning modalities. The implementation of discovery learning using virtual laboratories assisted by PhET Colorado can be an alternative learning model in teaching Physics. Future research can measure students' knowledge, attitudes or skills in applying differentiated learning and combining it with other learning models

Abstract

The helium ion is one of the ions classified as a hydrogenic atom because it has only one electron in its outer orbital so that the helium ion problem can be solved using the Schrodinger equation approach. The Schrodinger equation of the polar part of the helium ion can be solved by the associated legendary polynomial function, . The polar function expresses the angle formed by the vector of the electron's position relative to the z-axis of the helium ion's nuclear position. And it is produced that the polar function of the hydrogenic atom has the same polar function both in position space and in momentum space .

For obtaining the accurate data, the method of descriptive qualitative research is used by collecting the data, using the deep interview technique, direct observation and documentation. The analyze result shows that there is a quiet big waste potential in Sukamaju Village then processed to be the valuable manure. Moreover, this manure manufacture process is obtained from the palm oil waste from two big factories namely PT. Surya Agro Reksa and PT. Agrolestari. The process of waste production of palm oil includes the manufacture from the waste ponds, where the first pond of waste still has the high level of acidity so that it has not been able to be used yet. So the level of middle pond of waste water has been able to be channeled to the agriculture for make the plant fertile, and in the last level of solid waste is used as the natural manure of the land fertilizer. The analyze result shows that the waste of the palm oil can increase the fertility of land and plant, so it decreases the budget outcome of chemical manure. The socialization effort is needed to pressure massively for the information distributing connected the right waste processing.
