This study was intended to reveal the profile of students’ misconception of the concept of dynamic electricity in one private university in Cirebon city. In the study of physics, the misconception will hamper the achievement of physics learning goals. Misconceptions will greatly hinder the process of acceptance and assimilation of knowledge in students, so that they will hinder the success to learn more. It is necessary to conduct research on the analysis of misconception of mathematics teacher candidates on the concept of dynamic electricity. Misconception is defined as a student conception that is incompatible with the simplified conception of physicists. To identify misconceptions experienced by students, multiple-choice diagnostic tests equipped with a Certainty Response Index (CRI) can be conducted. The data obtained is then completed with interview data. This research is a descriptive research which is a research to give a description about phenomenon, or facts under study by describing the value of the variable without comparing. The study found that 81% of students’ have a misconception in the sub-chapter of electric current, and 50% in the concept of electric potential difference sub-chapter.

The aim of this study is to find out and analyze the effect of a worksheet based learning of rotational dynamics on students’ critical thinking skills viewed from IQ score and the correlation between critical thinking skills and the students’ IQ score. This research has been conducted in even semester of the academic year of 2017/2018, in university in Bandung area. All students in a university in Bandung City are the population for this study with the target population are all students in the first year in the university year of 2017/2018. The sample in this study is the first semester of Physics Education students as an experimental group, selected using purposive sampling technique, with data collecting tool in the form of written test of critical thinking skill and IQ. The research design used is one shot case design. A hypothesis test is done by using correlation and regression. The whole test of this data analysis used SPSS program. The results of this study indicate that the learning-based student's worksheet on the concept of Rotational Dynamics significantly influences students' critical thinking skills. It can be seen from the score of n-gain which is 0.5. Based on the calculation on correlation obtained value of 0.185 0.05, in other words, the students’ IQ score does not affect the students’ critical thinking skills. So it can be concluded that there is no correlation between IQ and critical thinking skills which seen from the results of correlation and regression analysis.

The aim of this research was to know the morphological diversity of Hibiscus rosa-sinensis through visual observation. The character of the qualitative and quantitative morphology of Hibiscus was analyzed descriptively. The result showed that there are 15 types of Hibiscus have morphological differences. There are two kinds of leaf shape that is ovatus and deltoideus. While The leaf base is obtusus, rotundatus and truncatus. The leaf apex includes acute and acuminate. All cultivars have a similar leaf margin that is serrate. The leaf colours are variable ranging from green, young green, dark green and variegate (combination between green and white). The flowers have 6 main color variations i.e beige, yellow, red, orange, pink and white. The corolla forms a single petal or a double petal, with two types of corolla uniquely buds and breech. It can be concluded that the cultivar of Hibiscus rosa-sinensis is variable in leaves and flowers.

Pineapple Plant ( Ananas comosus (L.) Merr) is a fruit plant that has a high economic value. Increased variety of pineapple preparations lead to increased demand for pineapple fruit. Polyploidation is one way to increase the varieties using colchicine. This study aims to know the pineapple explants of callus response after being treated by colchicine using in vitro method. This research used Group Randomized Design (GRD) which variations concentration of Colchicine 0%, 0.01%, 0.05%, and 0.1%. Parameters were observed to response and thickness of callus of pineapple explants. Data were analyzed using F test and DMRT test in which significance level of 5% with SPSS 17 program. The results showed that pineapple plant explant able to respond colchicine concentration marked with thicker callus. The best colchicine treatment to induce pineapple explants callus was concentration 0.1% of colchicine.

Aruk rice is an iconic rice from Province of Bangka Belitung which is made from cassava while purple aruk rice (PAR)e is made from sweet potato ( Ipomea batatas ). Ipomea batatas is a high nutritional food that possesses several medicinal value including anti-cancer, antidiabetic, and anti-inflammatory activities. This research aimed to assest the organoleptic features of PAR and analyze the effect of PAR consumption in lowering the BMI and bofody fat percentage. The design of this research was randomized crossover design with quasi experimental research within subjects single-factor two-level design. This experiment consist of three phases, phase 1 (plain rice consumption), wash out phase, and phase 3 (PAR consumption). The only different between two phases was the source of the carbohydrate. The data of decreasing BMI and body fat percentage betweern plain rice diet and purple aruk rice was analyzed by using paired t test. Organoleptic assessment showed that the aroma of PAR is dislikeable but the natural purple colour is likeable. The decreasing of BMI and body fat percentage was found higher in phase 2 (2,05±0,10) than phase 1 (0,4±0,14), p=0,002. The decreasing of body fat percentage was also found higher in phase 2 or purple aruk rice diet (2,55±0,25) compared to phase 1 plain rice diet (0,5±0,20), p=0,003. Consumption of aruk purple rice lower BMI and body fat percentage more effective than consumption of plain rice.

The examination of the acoustic characteristic of rice bran has been performed. The materials are the alternative materials of the noise controllerfrom the use of synthetic fiber materials like glasswool. The examination is completed by using tube impedance method. The result of the examination reveals that the natural fiber materials that have been mixed with glue have a good value of sound absorption at frequency 400-1200 Hz whereas at frequency 200 Hz, its value does not change significantly. The high value of the sound absorption is owned by materials with the bigger porous. Beside the coefficient of the absorbtion, the examination of value of acoustic impendence is also performed. The result shows that the similar composition between natural fiber and glue has a bigger value of impendence compared to the lower composition of glue. It is caused by the fulfillment of the bigger amount of the porous by glue.
