Abstract

Technological progress in the 21st century is progressing very rapidly, one of the fields that has an impact on the development of technology and knowledge is in the field of education. Where the development of technology is increasingly developing interactive multimedia-based media that can assist teachers in delivering material to students and students also more easily understand the material being taught. One of the media development software that has an effective, easy and attractive appearance to use is 3d pageflip. This research is a descriptive study with data analysis techniques using percentages which are then analyzed by descriptive techniques. This research refers to 10 articles that are relevant to the research, namely media development with 3d pageflip. The results of this study are obtained that the average articles developed already have valid criteria, the types of teaching materials that are mostly developed with 3d pageflip are EBooks and the materials developed are different from 10 articles there are 9 different materials developed.

Abstract

Silver nanoparticles are nano-sized particles ranging from 1-100 nm which are commonly used as antifungal and antibacterial agents in various products. In this study, silver nanoparticles were synthesized from a natural bioreductant, namely key orange peel extract. The silver nanoparticle phase which was successfully synthesized and then XRD test was carried out was cubic in shape with the highest peak at 2θ : 38.1959˚; 44.4038˚; 64.5491˚ The lattice parameter of silver nanoparticles is a=b=c= 4.0861 . The resulting crystal structure of silver nanoparticles is cubic with a crystallite size of 39.84 nm, in addition to XRD test, XRF test was conducted to determine the main constituent components of silver nanoparticles, while the main component of synthesized silver nanoparticles was Ag of 97.66%. Antibacterial activity of silver nanoparticles was indicated by the formation of inhibition against the growth of Staphylococcus aureus bacteria with a clear zone formed around 12.091 mm. Therefore, the antibacterial inhibition formed from the silver nanoparticles synthesized in this study can be classified as a strong antibacterial property.

Abstract

Dye-sensitized Solar Cell (DSSC) is a solar cell that uses dye as one of its components. DSSC is interesting to develop because it can be fabricated simply with low production costs. This study aims to develop a DSSC that uses dye-sensitized from natural ingredients to be environmentally friendly. We chose betel nut (Areca catechu L.) as a natural dye source because betel nut has a reddish-brown color and is often used as a natural dye. The stages of this research consisted of betel nut extraction, TiO2 deposition, manufacture of a carbon layer on the counter electrode, and DSSC fabrication. Measurement of DSSC performance under solar irradiation with an intensity of 292 W/m2 shows that the fabricated DSSC can produce a voltage of up to 216 mV with a current of 0.03 mA. Variations in the concentration of TiO2 positioned on the ITO substrate indicate that higher concentrations of TiO2 can produce higher DSSC voltages

Abstract

Research has been done on designing a mini power bank using dragon paste as a source of electrical energy. The voltage and current generated by this dragon paste and power bank are measured using a digital multimeter. Dragon paste is used in series and parallel. The voltage generated by the dragon paste is connected to a DC step up. The use of step-up dc aims to increase the dragon paste voltage so that it can or can charge lithium-ion batteries that have been arranged in parallel using the power bank kit module.

Abstract

Pearl clam shell waste can be decomposed as a result of CaO compounds. CaO is a compound that can be applied in various fields such as biomaterials, electronics, agricultural industries, and others, for example as a source of biological calcium which plays a role in the growth and survival of shrimp, lobsters, and fish. This study aims to examine the effect of Calcination Temperature on calcium oxide (CaO) characteristics of pearl clam shells (Pinctada Maxima). The procedures carried out in this study include the preparation of pearl clam shells (pinctada maxima), the formation of Calcium Oxide (CaO) using the calcination method which is then continued with the characterization of the test sample. The CaO characteristics studied include CaO characteristics such as CaO compound content, powder size, powder density, bulk density and porosity. The results of measuring the CaO characteristics of pearl clam shells with variations in calcination temperature get an increase in calcination temperature resulting in the CaO yield value tending to decrease with an increase in CaO levels. Bulk density is not particularly affected by calcination temperature, but powder density tends to increase with temperature increase, whereas, porosity and particle size have smaller values. Interestingly, the values of density and porosity are inversely proportional which is closely related to empty cavities or pores formed as a result of differences in calcination temperature.

Abstract

Researchers developed the Parallel Electrical Circuit Online Conceptual Survey (SKORLP) instrument into a four-tier diagnostic test. The purpose of the study was as a first step in the development of the SKORLP four-level test format into a diagnostic test instrument on Parallel Electrical Circuit materials. The research method used is a 4D model (Defining, Designing, Developing, and Disseminating). The instrument developed has been tested on 23 students in one of the MTs of South Jakarta. From the results of the study, it was found that the development of SKORLP in the form of a four-tier test allows it to be presented online and has great potential in producing student conception profiles in the parallel electrical circuit material, that is, students who understand the concept of Sound Understanding (SU), understand but partially or Partial Understanding (PU), misconceptions or Misconceptions (MC), do not understand the concept of Parallel Electrical Circuits at all or No Understanding (NU).

Abstract

The purpose of this study was to clarify the relationship between student learning independence and scientific learning outcomes. The method used in this survey is a survey. The population of this survey was class VIII Madrasah Tsanawiyah Negeri in South Jakarta, for a total of 720 students, and the sample size of this survey was 88 students. Sampling was performed using a combination of clustering, proportional, and random techniques. This survey data collection is in the form of a survey using the Likert scale model that respondents need to fill out and a data analysis using the SPSS 20 program. The result is a value of Sig = 0.000 < 0.05 and tcount = 3.727, H0 is discarded. This means that student learning independence is actively associated with scientific learning outcomes.

Abstract

The structure and thickness of the solar cell device layer have a big impact on how well the solar cell works. There for, the aim of this study was to examine how hydrogenated microcrystalline silicon solar cells’ thickness and device structure affected how well they work. Simulation or modeling of the structure in one dimension (1D) is used for the analysis. MATLAB programming was used to analyze the simulation result. The optical band gap changes due to the influence of the structure, therefore the thickness of the p-, I, and n layers are kept constant at 250 Å, 9000 Å, and 250 Å respectively. The results showed that the maximum performance is obtained at the optical band gap, Eci = 1,39 eV, and the resulting power is 0.063465 Watt. Whereas in the simulation of the effect of the thickness on the i-layer, the optical band gap is set to a constant value of Eci = 1,4 eV, while the thickness of the p-layer and n-layer is set to 250 Å. The results also indicate that the maximum performance is at the i-layer thickness of 9000 Å and the power generated is 0.063364 Watt.
