Abstract

This paper describes how the assignment method can improve teachers' abilities in analyzing SK and KD at SMPN 1 Tapung Hulu Kampar. Based on the description of the background, problem identification, and problem limitation, the focus of the research is related to the implementation of assignment methods to improve teachers' abilities in analyzing SK and KD at SMPN 1 Tapung Hulu Kampar. The research action hypothesis is "if the assignment method is applied, it can improve teachers' abilities in analyzing SK and KD at SMPN 1 Tapung Hulu Kampar Regency”. The type of research is school action research (PTS), which stands for determining the success of implementing the assignment method to improve teachers' abilities in analyzing SK and KD at SMPN 1 Tapung Hulu Kampar. The research location is at SMPN 1 Tapung Hulu Kampar. This research was carried out in February 2023 and the number of samples in the research was 28 teachers. Based on the description of data processing and discussion, it is concluded that the teacher's ability to analyze SK and KD was found in cycle I at 64.5% in the quite good category and in cycle II it increased to 77.9% in the good category.

Abstract

The demand for low-cost carbons with multi-doping in supercapacitors has led to a significant focus on utilizing biomass waste to produce activated carbons. The research successfully utilized Musa paradisiaca L. (MPL) peel as a porous carbon for solid-state supercapacitor. The process involved collecting banana peel waste, drying the peels using sunlight, pre-carbonization using a furnace, pH neutralization, drying, crushing carbon particles, and ensuring uniform particle size. Different concentrations of the catalytic ZnCl2 solution (300, 500, and 700 mmol/g) were selected to optimize physical and electrochemical properties. The resulting chemically activated MPL carbon powder was evaluated using SEM-EDS, XRD, and BET. MPL activated carbon with a 500 mmol/g solution of ZnCl2 was found to have optimal physical properties with a carbon percentage of 81.65%, oxygen 17.39%, phosphorus 0.42%, and boron 0.52%. Electrochemical properties were evaluated using dual-electrode system was exhibited the highest specific capacitance of 67 F/g. These findings demonstrate the potential of MPL peel waste as a high quality electrode for supercapaicor next-generation.
