Abstract

The purpose of this research is to analyze the problem solving ability of harmonic motion material. Problem solving skills are one of the important components of learning. Therefore, it is necessary to analyze the extent of student problem solving skills. The method used in this study is a descriptive analysis method with data collection techniques using the instrument of the description problem along with aspects of problem solving capability assessment. The subjects of this study were 24 physics education students who had obtained harmonic motion material. The results showed that students had difficulty in harmonic motion material. In the first phase of useful description, the average problem-solving ability of students was only 41.21%. The second stage of physics approach,the average student ability of 32.24%. The third phase of the specific application of physics, the average student's ability is only 14.21%. The fourth stage of mathematical procedure,student ability by 10.11%, the fifth stage of logical progession averages student ability by 2.23%. Therefore, it can be said that problem solving skills are still relatively low, so learning is needed that can improve students' problem solving skills. Based on the results of the analysis, it can be concluded that the most common mistakes made by students in solving physics problems are errors in the process of conveying results and assessing solutions. Mistakes that are rarely made by students are mistakes in understanding problems by using correct representations.

Abstract

Misconception is an understanding that is believed to be correct but not according to the understanding of the experts. Misconceptions can occur because students build their knowledge gained from daily activities. This study aims to identify misconceptions about Newton's law concept and the causes of the misconceptions. The research type is descriptive quantitative. A total of 30 students of SMA Multazam IBS Semarang were given a true-false objective test and drew a style diagram accompanied by a certainty of response index (CRI). The cause of the misconception was obtained by interviewing 4 students. The results obtained were as many as 20.99% of students experienced misconceptions, 9.99% of students understood the concept, and 69.02% did not understand the concept of Newton's law concept. The most common misconception is that students think that heavier objects will fall faster than lighter objects. The cause of students experiencing misconceptions is the understanding they build themselves; students' carelessness in choosing answers; low reasoning ability; and forget the material that has been delivered.

Abstract

Tofu is a food that people are fond of and is recognized as healthy, nutritious and cheap cuisine. The tofu industry has been growing rapidly in Indonesia in the form of household scale businesses or MSME (Micro, Small and Medium Enterprises). On the other hand, tofu industry also has a negative impact to the environment due to its waste. The waste of tofu industry has high level of BOD and COD so that it becomes organic pollutant for groundwater and creates an unpleasant odor. Tofu components that potentially become liquid waste are the organic compounds such as protein (40-60)%, carbohydrates (25-50)%, and 10% fat. The largest component of tofu liquid waste is protein, which is 226.06 mg/L to 434.78 mg/L. This nutrient content allows tofu liquid waste to be processed into liquid organic fertilizer through a simple fermentation process. In this community service project, short training on processing tofu industrial liquid waste into liquid organic fertilizer has been conducted in Sumurrejo are, Semarang. To utilize this organic fertilizer for plant growing, an alley garden was also established in the village.

Abstract

Cu-doped ZnO (ZnO:Cu) thin film was deposited on glass substrate using a sol-gel spin coating method. The film was prepared at various spinning rate followed by sintering at 250 °C for 10 min and annealing at 350 °C for 2 hours. The effect of spinning rate on structural properties was investigated by means of X-ray diffractometer (XRD), scanning electron microscope (SEM) equipped with energy dispersive X-ray (EDX). The diffraction pattern indicated that Cu-ZnO thin films showed a strong c-axis orientation, i.e. the peak attributed to (002) plane at a of corresponding to hexagonal wurtzite crystals. An increase in the spinning rate resulted in ZnO:Cu thin films with high homogeneity. It was further proved by SEM and EDX results.

Abstract

Scientific literacy skills are very important in the era of globalization, where science and technology are rapidly developing, especially in developed countries. Science and technology in particular have a very big role in improving the quality of a country's education. The low scientific literacy of students in Indonesia makes Indonesia rank 70 out of 79 countries participating in international scientific literacy assessments. Students 'scientific literacy skills must receive special attention, namely by looking for causes and efforts to improve students' scientific literacy, especially in Indonesia. The research objective is to determine the causes of low scientific literacy and how to improve it to assess the integrity of students' scientific literacy by mapping the research results from previous research at the science education level for both junior high and high school students. The type of research method used is the SLR (Systematic Literature Review) method. This research method is carried out by reviewing and identifying journals systematically with data results in the form of qualitative descriptive analysis.
