Abstract

This study aims to determine the structure of morphology and functional groups from activated charcoal for palm oil waste with variations in activation temperature. The process of two stages: the carbonation and activation stage. Carbonation process using a pyrolysis reactor at a carbonation temperature of 200oC -400oC for 6 hours. Then, the sample activated at a temperature of 700 °C, 750oC, 800oC, and 850 °C. Samples were characterization using SEM and FTIR. SEM analysis results show the largest pore size at a temperature of 850 oC with a diameter of 48.3 nm, and the lowest temperature was 700 °C with a capacity of 35.3 nm. Activated charcoal from oil palm shell waste at mesopore size. Next, FTIR analysis results show wave numbers 2165,18 cm-1, 1554 cm-1, 1030,76 cm-1 dan 424,11 cm-1.  The removal of some absorption bands and  the formation of new absorption bands, caused by the activation temperature

Abstract

This research-based on technological advances that promote the use of technology in learning, on the lack of valid, practical and effective lesson plans, particularly in problem-based learning models that are in line with the 2013 curriculum, and on the use of Lectora Inspire Software in the creation of lesson plans. This study was conducted to develop a product that is a problem-based learning model based on Lectora Inspire software, and that is valid, practical and effective. This type of research is research and development (research and development). The design of this study based on 5 out of 10 phases of Borg and Gall's research design, namely research and collection of initial information, planning, development of original product formats, initial testing and product improvement. The effectiveness test results were rated as very good if the results of the analysis of the responses of teachers and students with an average of 88% and 89.04% as and the increase (n-gain) of student learning outcomes is 0.62 which can be categorized as a moderate increase.

Abstract

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 °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.

Abstract

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 0° up to 90° compared without automatic drive.  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 × 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. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  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.

Abstract

The purpose of this research is to develop a student's conception of mechanical energy conservation with the Interactive Lecture Demonstration method. The participants consisted of 19 students of class 7E SMP Muhammadiyah 1 Mlati in 2018/2019 academic year. The analysis of the student's sheet prediction showed that most students do not understand the conception of mechanical energy conservation. After learning applied, it is known that all students have understood the influence of the height of the object on potential energy, 18 of them have understood the influence of the mass of the object on potential energy. While students' understanding of changes in mechanical energy when objects fall and the influence of mass on kinetic energy has increased slightly. Through the Wilcoxon signed-rank test, it was concluded that there was an effect of the use of interactive demonstration methods on student learning outcomes in the matter of mechanical energy conservation conceptions.
