Abstract

A magnetite (Fe3O4) thin film was grown on the Indium Thin Oxide (ITO) substrate by the Electrodeposition (ED) method, using the Continue Direct Current (CDC). Characterization with VSM is done to obtain information about the magnitudes of magnetic properties as a result of changes in the external magnetic field depicted in the hysteresis curve. VSM characterization results showed that the electrodepositioned magnetite thin films were paramagnetic, both for electrolyte solutions without ethylene glycol and electrolyte solutions that were dropped by ethylene glycol. Based on the comparison of the hysterisis pattern between samples that were characterized without surfactants, or those added with 10% surfactant to their solvents, it was said that the addition of ethylene glycol to base solution, affected the response of the material to the given external magnetic field. Samples with surfactants 10% have a greater slope than samples without surfactants, in other words samples without surfactants (by heating) are faster magnetized compared to the addition of surfactants.

Abstract

This study aims to look at student learning activities using cooperative script models. This is motivated by the lack of optimal implementation of learning using various models, while students tend to be passive and show less interest in learning. Student activity is mainly seen from 2 activities namely writing activities and listening activities. The method used in this study is quasi-experimental methods, the sampling used is cluster random sampling with 2 sample classes. The results showed a significant number of increased student learning activities using this model. The data obtained by the experimental class obtained one very good information (A) for visual activities and one good information (B) for writing activities, while the control class got two good (B ) for both aspects studied. Based on this it can be concluded that student learning activities using cooperative script models have increased when compared with conventional learning

Abstract

A cigarette smoke monitoring system in school toilets has been designed using  MQ-7 sensor and  transceiver nRF24L01+ with ISD 1820 module based sound output. This hardware system consists of two units that is a transmitter and  receiver. The transmitter unit consists of a MQ-7 sensor, a transceiver circuit nRF24L01+, Arduino Uno R3. The receiver unit consists of transceiver circuit nRF24L01+, LCD, Arduino Uno R3, ISD 1820 module. The MQ-7 sensor functions to detect carbon monoxide gas in cigarette smoke.  MQ-7 sensor characterization obtained transfer function y = 0.0635x + 0.3808 with a regression value of R2 = 0.9808. The error value obtained from the comparison of gas read by the MQ-7 sensor with a biogas analyzer is 5.35%. The transceiver nRF24L01+ test obtained that the maximum distance of data transmission is 502 m without barrier and 68 m with wall barrier. The overall design of the device can function properly, the MQ-7 sensor can detect carbon monoxide gas as far as 110 cm and when the concentration is more than 1 ppm the speaker on the ISD 1820 module will be activated as a warning alarm.

Abstract

Perkiraan meningkatnya permintaan dunia terhadap komoditi karet dimasa yang akan datang menjadi latar belakang utama penelitian ini. Seiring dengan hal itu, maka upaya peningkatan kualitas dan kuantitas hasil produksi karet juga menjadi hal perlu diperhatikan. Untuk mendukung upaya tersebut, perlu dilakukan penelitian tentang kondisi tanah yang menjadi tempat tumbuh dan berkembangnya tanamannkaret. Tujuan dari penelitian ini adalah untuk menentukan ukuran bulir dan jenis domain magnetik dari tanah subur dan kurang subur pada perkebunan karet daerah Rimbo Bujang, Kabupaten Tebo, Jambi. Penelitian ini dilakukan terhadap 34 sampel tanah perkebunan karet dan sawit. Adapun sampel terdiri dari 24 sampel yang diambil dari lokasi Karet Subur, 10 sampel dari lokasi Karet Kurang Subur pada perkebunan karet daerah Rimbo Bujang, Kabupaten Tebo, Jambi. Ukuran bulir dan jenis domain magnetik ditentukan dengan metoda kemagnetan batuan melalui pengukuran Anhysteretic Remanent Magnetization (ARM). Sampel dimagnetisasi dengan alat pARM (Partial Anhysteretic Remanent Magnetization), kemudian magnetisasi sampel diluruhkan dengan menggunakan Molspin AF Demagnetization. Untuk mengukur intensitas magnetisasi dari sampel digunakan Minispin Magnetometer. Setelah dilakukan plot hubungan antara medan H dengan nilai intensitas relatif, didapatkan hasil bahwa sampel tanah karet subur mempunyai ukuran bulir magnetik 6 sampai 20  yang tergolong kepada jenis domain pseudo single domain (PSD), sedangkan untuk sampel tanah karet kurang subur berkisar 110 sampai 135  yang tergolong pada jenis domain multi domain (MD).

Abstract

his research is motivated by the low learning outcomes of students, namely the same treatment given by educators to students in the classroom, whereas each individual has different characteristics or different abilities. Educators should adjust the learning model that is appropriate to the ability of each student, because students are smart, medium, and low. Besides that other causes include conventional learning,  educators only provide formulas without using interactive, interesting, fun and not boring media for learning, then giving training to students. This study aims to find out that the learning outcomes of science students by applying the Trait Treatment Interaction (TTI) learning model is better than conventional learning in class VIII MTsN Durian Tarung padang. This type of research is Quasy Experiment with Randomized Control Group Only Design design. The sample was selected using Cluster Random Sampling technique and obtained class VIII5 as an experimental class and class VIII6 as a control class. Analysis of test data using t-test statistical techniques with a significant level, obtained t count> t table thitung. So, it can be concluded that the application of Multimedia Swishmax 4.0-assisted TTI model provides better science learning outcomes than conventional learning in the eighth grade MTsN Durian Tarung Padang.

Abstract

The purpose of the study was to analyze the blended learning models used in various educational institutions. These blended models become references for educators who want to apply this model in their learning. The research method uses library research. The results of this research can be seen from many blended learning models used by various educational institutions. There are four MBL developed in US educational institutions, namely: rotation, flex, Self-blend and enriched-virtual models. There are also three possibilities for the development of MBL learning in education, namely web courses, web centric courses, and web enhanced courses. In addition, there are also five levels of ICT use in learning. Each model and type has advantages and disadvantages. Educators can combine or modify these models according to the conditions of their respective educational institutions..

Abstract

Android-based learning media is a way to deliver material in the teaching and learning process using Android as a tool, almost all students now have a smartphone, but only used for social media, playing games and sending instant messages such as WhatsApp, very rarely used in the learning process, so it will it is better if the smartphone is used as a learning medium, one of which is by making learning media in the form of applications using appypie. The application in this study contains competencies, teaching materials, sample questions, learning videos, quizzes and verses of the Qur’an related to the subject. The research method used is Research and Development (RnD) with the development process using the 4D model (Define, Design, Develop and Desseminate). This study is to look at the validation of the media application for the independence of student learning.the results of this study indicate that Appypie-based media are valid in language, material and appearance, and can be recommended to support student learning independence
