The Effect of Electrode Gap on the Nucleation of CaCl2.6H2O by using Sharp End Copper Electrode Putri, Risky Afandi; Swandi, Ahmad; Rahman, Annisa; Anggraeni, Radhiah; Sutjahja, Inge Magdalena; Kurnia, Daniel

The performance of the calcium chloride hexahydrate (CaCl2.6H2O) to store the sensible and latent heats is mainly determined by its nucleation or liquid to the solid phase transition. This is due to the barrier that has to be overcome when the material undergoes the nucleation process with a reduction in the entropy value. This material, with melting temperature around 29.8 Â°C, can be used as the thermal energy storage for building applications in tropical areas such as Indonesia, in order to reduce the electrical energy for aircond (AC) machines. In this paper, we report the results of an experimental study for the effect of the electrical field to the supercooling degree and time period for a phase transition. The variation in the magnitude of the electrical field was achieved by variation in the gap of the electrode for sharp end electrodes (cathode and anode), for the commonly sold copper electrode.

This study aimed to determine the volume of traditional eucalyptus oil from distillation with variations in fluid flow velocity. The method of distillation was distillation with water (water distillation). The material was eucalyptus leaves. To determine the volume of eucalyptus oil produced by distillation, the distillation device was set at the height of the condenser to the source of flow fluid, which was at an altitude of 15 cm, 25 cm, 35 cm, 45 cm, and 55 cm. Variation in the height of the condenser would affect the fluid flow rate. The faster the fluid flow rate, the greater the convection coefficient so that it increased the heat transfer rate. This results in greater volume (capacity) of oil produced. From these experimental results, most volumes of eucalyptus oil obtained from the distillation was obtained at 55 cm of the height of condenser with 3.6 mLof oil volume.

This study aims to measure the increase in student learning outcomes from cognitive aspects and student activity between active quiz type learning methods and conventional methods. The sampling technique is non-random sampling. Data was collected using the pre-test and post-test for cognitive aspects while the affective aspects used the observation. Analysis of the data used the normality test, homogeneity test, and hypothesis testing. The hypothesis test used is a two-party t test. The results show that tcount= 7.273 > ttable= 2.01 at a significant level of 5%. It means that there are significant differences for cognitive aspects between learning outcomes using the team quiz type and conventional methods of active learning methods. Overall the team quiz method is more effective for improving student learning outcomes from cognitive aspects, and student activities.

The Penetration of Mobile Technology and Its Implementation on Learning in Indonesian High School Sulisworo, Dwi; Muqoyyanah, Muqoyyanah
Indonesian Review of Physics (IRiP) Vol 1, No 1 (2018)
Publisher : Universitas Ahmad Dahlan

The use of a smartphone as a mobile learning tool in schools is controversial. On the one hand, the teacher prohibits it because it would interfere with the learning process in the classroom; and on the other hand, the teacher saw a lot of potentials can be used from mobile technology. The goal of this study is to describe how the development of secondary schools in Indonesia can facilitate students through the use of mobile learning with the hope that it can be taken at the school level policies to strengthen the existing learning system so that students can achieve optimal learning competencies. This research used descriptive qualitative evaluations to make observations on the application of mobile learning in several secondary schools in several regions in Indonesia during 2015. The results of this study indicate that some of the schools that have implemented mobile learning have a tendency that mobile learning was not planned and structured as a school program; so that the advantages of mobile technology has not been effectively used. Two important things to solve this condition are the availability of government policy and improving teachers literacy in managing mobile learning application.

Determination of Fill Factor and Efficiency in Solar Cell Type (99 Ã— 69) mm2 with Arduino Uno R3 Based Drive assisted by Logger Pro 3.14.1 Hamzah, Hamzah; Toifur, Moh.; Ishafit, Ishafit

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0Â° up to 90Â° compared without automatic drive. Â The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 Ã— 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software.Â The result show that it has been successfully designed an automatic driver of a solar panel (99 Ã— 69) mm2Â with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.

An Analysis of Graduate Studentsâ€™ Conceptual Understanding in Heat and Temperature (H&T) Using Three-Tier Diagnostic Test Sukarelawan, Moh Irma; Jumadi, Jumadi; Rahman, Nurulhuda Abdul

There have been many studies that investigate H&T misconceptions among students in Indonesia but the respondents are usually limited to senior high school students. This study aims to analyse the conceptual understanding in H&T concepts of Masters of Physics Education students with a focus on identifying their misconceptions.The study employs the survey research design and data were collected using a three-tier diagnostic test. Twelve Masters of Physics Education students who are enrolled in one of the private universities in Yogyakarta City took part in the study. They were selected using the convenient sampling technique. Data on conceptual understanding involve both quantitative and qualitative data. As such, the data was analysed based on the percentage of student response patterns. Results showed that the majority of students (62.5%) have some form of misconceptions about the concepts of H&T and only 22.9% hold the scientifically accepted conceptions. The most common misconception held by the students is that both H&T depend on the material of an object. Other descriptions of conceptual understanding are False Positive (4.2%), False Negative (4.2%), and Lack of Knowledge (6.2%). Interestingly, none of the students made a lucky guess in responding to the test items. We conclude that the pattern in conceptual understanding specifically that of misconceptions are ubiquitous regardless of the level of study. Years of learning have failed to address misconceptions among students even at the graduate level. This result has implications on how learning should be designed to actively resolve the issue of misconceptions among students.Â Â
