Abstract

The usage of porphyrin as a light-harvesting chromophore is considered as one of the keys to obtaining low-cost and high-efficiency dye-sensitized solar cell (DSSC). In this paper, a novel porphyrin, 5,10,15-tris(nitrophenyl)-20-(p-(11-bromo)dodecoxyphenyl))porphyrin, having a long alkyl chain and three nitro groups was synthesized. The nitro groups serve as anchoring groups to TiO2 surfaces and long alkyl chain prevents unwanted dye aggregation. The porphyrin was synthesized by condensation of p-(12-Bromododecoxy)benzaldehyde and pyrrole in propionic acid according to an adaptation of the general Rothemund method [1]. p-(12-Bromododecoxy)benzaldehyde was synthesized by nucleophilic substitution reaction between 4-hydroxybenzaldehyde and 1,12-dibromododecane in acetone. The reaction products were analyzed by 1H-NMR and mass spectroscopy. The absorption and fluorescence spectra of the porphyrin were also recorded. As results, the absorption spectrum of the porphyrin consists of a strong Soret and four weak Q-band. Compared to 5,10,15-tris(nitrophenyl)-20-(p-(11-bromo)dodecoxyphenyl))porphyrin spectrum, there is no wavelength shifting because of the incorporation of the alkyl chain. The fluorescence spectrum of the porphyrin shows two characteristic emission bands and the intensity ratio of those emission bands is always constant when irradiated by different excitation wavelength related to Soret and Q-band.

Abstract

Low learning activity in science students causes a decrease in critical thinking skills. This can be seen from the results of learning redox material under the Kriteria Ketuntasan Minimal (KKM) of 75 in one of the high schools in Cirebon. Therefore, this study aims to improve students' critical thinking skills by using the Science, Technology, Engineering, and Mathematics (STEM) model for redox material in class X IPA MAN 1 Cirebon City. The research method used a Nonequivalent Control Group Design. Sampling was carried out by Purposive sampling consisting of class X IPA 5 as an experimental class and class X IPA 4 as a control class. The instruments used are critical thinking ability tests, observation sheets, and questionnaires. The selection of a sample based on the KKM of a class was revealed from discussions with a chemistry teacher. The development of the T-test obtained a sig value. 0.000 0.05 and an n-gain score of 0.71 with the highest category. The results showed improved critical thinking skills after being given STEM learning. Students respond very well to the teaching that has been done using the STEM model. Based on the results of the t-test and N-gain test, it can be concluded that the Science, Technology, Engineering, and Mathematics (STEM) learning model can improve students' critical thinking skills on redox material.

Abstract

Chemistry learning, especially in Indonesia, has not been able to direct students to master critical thinking skills. Using appropriate media and learning models can improve students' critical thinking skills. One of the efforts to improve critical thinking skills is using Chemsketch media with STEAM-based learning models (Science, Technology, Engineering, Art, Mathematics). This study aims to analyze the effect of using ChemSketch in STEAM-based learning (Science, Technology, Engineering, Art, Mathematics) on improving students' critical thinking skills on chemical bonding material. This study used a Non-equivalent control group design. The population in this study were all grade X students of SMA Negeri 1 Karangwareng in the 2023/2024 school year, with the samples used including one class X-7 as the experimental class and one class X-6 as the control class. The data obtained were then analyzed using the N-Gain and simple linear regression tests. The results showed that: 1) STEAM-based learning significantly increases critical thinking skills with an N-Gain value of 0.66. 2) STEAM-based learning significantly affects critical thinking skills with a value of 0.002. It can be concluded from the results of this study that students in the experimental group experienced a significant increase in critical thinking skills compared to the control group. This indicates that integrating ChemSketch in STEAM-based learning can be an effective strategy to improve students' ability to analyze, evaluate, and solve problems related to chemical bonding.
