Abstract

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.

Abstract

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.

Abstract

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 bof√≥dy 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¬Ī0,10) than phase 1 (0,4¬Ī0,14), p=0,002. The decreasing of body fat percentage was also found higher in phase 2 or purple aruk rice diet (2,55¬Ī0,25) compared to phase 1 plain rice diet (0,5¬Ī0,20), p=0,003. Consumption of aruk purple rice lower BMI and body fat percentage more effective than consumption of plain rice.¬†
