Abstract

This study aims to describe the misconceptions of seventh grade students in science materials, especially temperature, heat, and expansion materials at SMP Negeri 28 Padang. The type of research used in this misconception research is descriptive quantitative. The sample in this study were 29 seventh grade students at SMP Negeri 28 Padang in the 2022/2023 academic year who had learned the concepts of temperature, heat, and expansion. The data collection technique used was a diagnostic test. The data analysis technique in this study consists of several steps, including classifying student answers to determine misconceptions about temperature, heat, and expansion material with a percentage of categories of understanding the concept, not understanding the concept, misconceptions, and guessing. Based on the results obtained, it can be concluded that there are several things that cause misconceptions, which include the lack of student interest in learning because it is influenced by the thought that learning science is difficult, the lack of teacher confirmation regarding concepts that students understand, the learning process that is still teacher-centered, and the absence of a fixed learning resource so that the teacher becomes the most dominant source of information for students.

Abstract

Natural soaps made from vegetable ingredients are increasingly popular nowadays, especially those known as natural soaps. The vegetable oil content of plants makes it called natural) and its advantage lies in its ability to moisturize the skin without leaving potentially harmful chemical residues. The research method used is a laboratory experimental method using descriptive analysis, so that it can provide information regarding the manufacture of solid soap. In this research on making solid soap, a pH test analysis or degree of acidity was carried out. pH is used to determine the alkaline and acidic levels of a solution. Acidity is the concentration of hydrogen ions in the water solvent. Soap that has a high pH occurs due to soap hydrolysis. A good soap pH value is soap that has a pH of around 7. Organoleptic testing on solid soap that has been made is carried out by observing the aroma, amount of foam and texture of the soap. This test aims to determine the quality of the soap that has been made. Making organic solid soap is expected to be able to produce products that are safe and of course comfortable for the skin without any side effects and are environmentally friendly. Soap that has a high pH occurs due to soap hydrolysis.

Abstract

Soap is one of the essential needs in everyday life. A mixture of olive oil, virgin coconut oil (VCO), and palm oil can be processed into soap bars using the cold process method. This soap making process involves the saponification reaction of oils and fats with NaOH. Cooking oil, as one of the commonly used sources of fatty acids, also plays a role in soap making. This research aims to utilize natural ingredients such as palm oil, olive oil, and VCO (Virgin Coconut Oil) in the production of solid organic soap. In addition, this research also investigates the impact of adding coffee powder on the texture, color, and aroma of the soap produced. The main focus of this research was to create high-quality soaps from natural ingredients, especially coffee, with the aim of providing beauty benefits and improving skin smoothness. During the research, it was found that the soap hardens within 2 weeks, while the total saponification process time requires 4-6 weeks for the soap to be safe for use. The significance of this research lies in understanding the effect of the mixture of palm oil, olive oil, and VCO in making soap bars, as well as the effect of adding coffee powder extract. The results of the study are expected to provide in-depth insight into the optimal formulation to create quality solid organic soap.

Abstract

Soap, as a cleaning agent, is produced through a saponification reaction between oil and a strong base (NaOH), producing glycerol as a by-product. In this case, experiments were carried out using the cold process method to explore making soap with the addition of papaya extract. This research also involves analyzing the quality of soap through organoleptic tests and acidity degree (pH) analysis. The organoleptic test results showed that the soap had an appropriate texture, sufficient foam, and an attractive color after dyeing. Implementation of the saponification reaction with NaOH requires precision and accuracy of measurements for the success of the process. Apart from that, the use of essential oils and the proportion of NaOH affect the quality of the soap. The curing process is carried out for ± 30 days to optimize the quality of the soap. This research aims to produce good quality soap, with a focus on evaluating organoleptic tests and acidity levels as indicators of success.

Abstract

This research is based on the preliminary study conducted at SMPN 16 Padang which found that students' learning outcomes in science teaching are still considered suboptimal. This is indicated by several students' scores that have not yet met the Learning Outcome Completion Criteria of 80. This research aims to determine the effect of Problem-Based Learning (PBL) model assisted by PhET simulations on the learning outcomes of eighth-grade students at SMPN 16 Padang. The type of research is a quasi-experiment with a non-equivalent control group design. The population in this study is all the eighth-grade students of SMPN 16 Padang. Sample collection was conducted using purposive sampling techniques. Thus, the research samples were obtained from students in class VIII 2 and VIII 4. The research samples consisted of experimental class applying the Problem-Based Learning model assisted by PhET simulations and control class using the conventional learning model. Data collection was conducted through tests administered before (pretest) and after the treatment (posttest) on the experimental and control classes in the form of multiple-choice questions. The obtained data were analyzed using inferential statistical analysis, and the results of the two-sample t-test for the pre-test and N-gain were 0.002 for the pre-test significance and 0.000 for the N-Gain significance, which means  was rejected or there was a significant difference between the two groups because the significance value (p) was less than 0.05. Thus, it can be concluded that there is a significant influence of the application of the PBL learning model assisted by PhET simulations on the learning outcomes of eighth-grade students in the subject of light and optical instruments.
