Abstract

Ideally, students who study Computational Physics are required to think computationally. However, student learning outcomes tend to be low. Low learning outcomes are suspected by students having difficulties. One of the causes of learning difficulties is students' attitude in responding to learning. This study aims to determine student attitudes in studying Computational Physics and the factors influencing student learning difficulties. This research is descriptive research with a quantitative approach. The population in this study were students of Physics FMIPA UNP. The sample in this research is students who take Computational Physics courses in January-June 2021. The data analysis technique used is the multivariate analysis based on factor loading testing with Confirmatory Factor Analysis (CFA) using Lisrel 8.80. The results showed that students' attitudes toward Computational Physics were good, with a percentage of student responses of 67.16%. Factors that influence learning difficulties are internal factors in the form of psychological factors in the aspect of interest (65%), motivational aspects (58%), and aspects of study habits (49%). Meanwhile, external factors do not affect students' difficulties in studying Computational Physics. Further research, it is necessary to carry out a similar analysis by taking into account other factors that are thought to influence the attitudes and difficulties of students in studying Computational Physics, both internal and external factors, so that they are better in determining the next steps to overcome student difficulties in studying Computational Physics.

Abstract

Drug abuse is a negative/irrational behavior that can harm oneself and others. One of the causes of drug abuse is the low self-control of students. Clients who have problems with low self-control in drug abuse need to be counseled through rational emotive behavior therapy in group settings. The aims of this study were: (1) to test the significant difference in the level of self-control of the experimental group students before and after being given the rational emotive behavior therapy setting technique, (2) to test the significant difference in the level of self-control of the control group students before and after being given services without treatment specifically, (3) examine the effectiveness of the rational approach to emotive behavior therapy setting in groups in increasing self-control in preventing drug abuse. This study used a quasi-experimental non-equivalent control group design with pretest and posttest. The research subjects were students of class VIII-3 and VIII-4 at SMP Negeri 4 Padang Pariaman with a sample of 20 people who were divided into 2 groups consisting of 10 people as the experimental group and 10 people as the control group. The sampling technique was purposive sampling technique. Data were analyzed using the Wilcoxon signed Rank Test and Kolmogorov Smirnov 2 Independent Samples with the help of SPSS version 20. The results showed that the rational emotive behavior threapy approach was effective in increasing students' self-control in preventing drug abuse. This can be seen from: (1) there is a significant difference in the level of self-control of the experimental group students before and after being given the rational emotive behavior therapy setting technique, (2) there is a significant difference in the level of self-control of the control group students before and after being given services without treatment specifically, (3) there is the effectiveness of the rational approach to emotive behavior therapy setting in groups in increasing self-control in preventing drug abuse. The implementation of the rational emotive behavior therapy setting approach in groups should be intensified in the form of Guidance Counseling programs and designed as well as possible by counsellors or Guidance Counseling teachers.

Abstract

Research has been carried out on the analysis of the optical properties of Fe3O4/PANi nanocomposites synthesized by the sol-gel method using spin coating. The purpose of this study was to determine the crystal structure, crystal size, surface morphology, and optical properties of the Fe3O4/PANi nanocomposite thin films. One of the applications of optical properties is that it can be used as a semiconductor. In this study, the primary material used was iron sand obtained from Oyster Beach, Padang Pariaman Regency, West Sumatra. Iron sand contains a magnetite (Fe3O4) phase, which has the highest magnetic properties, and the polymer used is a type of polyaniline polymer (PANi) which has good chemical stability. Fe3O4 acts as a filler, while PANi acts as a matrix. In this study, five variations of the composition of Fe3O4 in PANi were used, namely 30%, 40%, 50%, 60%, and 70%. For the method used, namely the sol-gel method and sample testing using XRD, SEM, and UV-Vis Spectrophotometer characterization tools. The results of the XRD characterization showed that each addition of PANi into Fe3O4 did not affect the resulting crystal structure and had a crystal size below 100 nm. SEM testing revealed the presence of agglomeration and particle size at variations of 30%, 40%, 50%, 60%, and 70% were 27 µm, 53 µm, 61 µm, 84 µm, and 46 µm respectively. And the results of the UV-Vis Spectrophotometer test obtained energy gap values for variations in the composition of Fe3O4 in PANi, namely 30%, 40%, 50%, 60%, and 70%, respectively, namely 2.51 eV, 2.39 eV, 2.18 eV, 2.35 eV, and 2.30 eV. Based on the research results, it can be proven that the Fe3O4/PANi nanocomposite thin layer is a semiconductor material because it is in the range of 0-3 eV.

Abstract

Graphene Oxide or Graphene Oxide (GO) Is a graphite oxide in the form of a monolayer obtained from exfoliating graphite oxide into sheets through a sonication or stirring process. In this study, the material used was a mixture of pure graphite and seaweed (Sargasum sp). Seaweed (Sargasum sp) is used as a mixture of pure graphite because the carbon content in seaweed (Sargasum sp) is good enough to reduce the use of pure graphite as the main ingredient in making graphene oxide. There are are 4 variations of composition with the aim of seeing the best results from these five compositions, namely the composition between Graphite and Sargassum sp, namely 70%: 30%, 60% ; 40%, and 50% : 50%. The research results obtained showed that graphene oxide had been successfully synthesized from the addition of seaweed charcoal because of some of the typical properties of graphene oxide. By X-ray diffractogram at an angle of 2, it was found to contain C-O, C=O, C=C, and O-H functional groups. In the VNA test, it obtained high reflection loss and adsorption coefficient values in a mixture of 50% pure graphite: 50% seaweed with a reflection loss value of -7.40 dB and an adsorption coefficient of 0.57342
