Abstract

A virtual laboratory for electrical materials has been developed in this study. The virtual laboratory was developed as an alternative laboratory due to the limited equipment of physics experiments and simultaneously assisting students in visualizing abstract concepts in physics. This article discusses the results of testing on the effects of virtual laboratories on improving the creativity of prospective physics teachers. Measurable creativity includes verbal and figural creativity. The model testing process uses the quasi-experimental method. The participant of this research is prospective physics teachers in Faculty of Teacher Training and Education, University of Mataram. The research instrument used in the form of tests of verbal and figural creativity related to the electrical material being studied. The results showed that there is a difference in the improvement of prospective physics teachers’ creativity after learning in both groups. In general, the increase in creativity in the experimental group is higher than the control group. The increase in verbal and figural creativity of the two groups also differed significantly. In both groups, the increase of verbal creativity is higher than that of figural creativity. This suggested that the developed virtual lab model proved to enhance the creativity of prospective physics teachers.

Abstract

Penelitian ini bertujuan untuk membuat biomaterial substitusi tulang yang menyerupai komposisi tulang sebenarnya, yang terdiri dari mineral inorganik (apatit) dan bahan organik sebagai matriks. Pada penelitian ini metode presipitasi digunakan dalam pembuatan komposit apatit-kitosan dengan menggunakan cangkang telur ayam dan bebek sebagai sumber kalsium dan KH2PO4 sintetik sebagai sumber posfat. Cangkang telur dan KH2PO4 sebagai mineral inorganik tulang, sedangkan matriks organik yang digunakan adalah kitosan dari kulit udang. Cangkang telur ayam dan bebek dikalsinasi untuk menghilangkan semua komponen karbonat (CO3) sehingga didapatkan CaO sebagai sumber kalsium. Komposit apatit-kitosan dibuat dengan menumbuhkan senyawa kalsium posfat pada matriks dengan metode ek situ. Sampel yang dihasilkan selanjutnya dikeringkan pada suhu 50 oC. Karakteristik sampel selanjutnya dianalisis menggunakan X-ray Diffraction (XRD) dan Fourier Transform Infrared (FTIR) Spectroscopy. Pola XRD sampel memperlihatkan adanya puncak-puncak difraksi untuk kristal apatit. Data tersebut didukung oleh spektrum FTIR yang memperlihatkan puncak transmitansi dari fosfat dan karbonat dari kristal apatit. This study aimed to develop bone substituted biomaterial consisting of inorganic mineral (apatit) and organic material as matrix. In this study, a precipitation method of apatite-chitosan composite synthesis has been used using hen’s and duck’s eggshell as calcium source and synthetic KH2PO4 as phosphate source. The eggshell and KH2PO4 act as inorganic mineral, whereas organic matrix used was chitosan originated from shrimp shell. The eggshell was calcinated to decompose all the carbonate (CO3) phases. To produce the composite, calcium phosphates were grown on organic matrix of chitosan using ex situ method. The result samples were further dried at 50 oC. Characteristic of the samples were performed using X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) Spectroscopy. The XRD profile illustrated specific diffraction angles at peaks of apatite crystals. This data were supported by FTIR spectra that showed transmittance peak of phosphates and carbonates from apatites.

Abstract

Penelitian yang telah dilakukan adalah pembuatan dan penghitungan kualitas citra digital menggunakan program Modulation Transfer Function (MTF) pada sistem Computed Radiography (CR) untuk kegiatan Quality Control (QC). MTF dapat digunakan untuk menganalisis resolusi spasial citra digital secara akurat. Pada penelitian ini menggunakan phantom yang terbuat dari tembaga berukuran 15x15 cm dengan ketebalan 1 mm. Phantom dieksposi dengan variasi tegangan 50 kV, 60 kV, 70 kV dan 81 kV dan masing-masing dilakukan variasi arus. Data yang diperoleh berupa file citra digital radiografi format DICOM yang kemudian dilakukan analisis kualitas citranya menggunakan PC diluar sistem CR dengan metode MTF. Metode ini sangat efisien dalam melakukan QC resolusi spasial secara kuantitatif sehingga dapat digunakan untuk menilai kualitas pesawat CR. Hasil pengukuran menunjukkan bahwa semakin tinggi tegangan yang digunakan, maka kualitas citra semakin baik dengan arus optimal pada rentang 4-8 mAs dengan rata-rata nilai resolusi spasial 7,26 lp/mm.The research was analyzing of digital image quality by using Modulation Transfer Function (MTF) on Computed Radiography (CR) system for Quality Control (QC). MTF can be used for analyzing digital image spatial resolution accurately. The research used phantom that made of 15x15 cm2 copper and 1 mm thickness. The phantom was expounded with voltage variations by 50 kV, 60 kV, 70 kV dan 81 kV and each of them have been taken by variations of the current. The the image quality of data obtained in the form of radiography digital image files with DICOM format were then analyzed using PC out of CR system with methode of MTF. This methode is really efficient for QC spatial resolution quantitatively and so it can be used for assesing the quality of CR. The measurement results showed that the higher the voltage, the better image quality with optimal current was on the range between 4-8 mAs with the average value of MTF 7,26 lp/mm.

Abstract

The aim of this study is to explore the impact of interactive-conceptual-instruction with visualization on logic thinking, conceptual understanding and spiritual aspect embedding. The sampling technique used in this research was convenience sampling. This research used mixed methods with embedded experiment design. The data of logic thinking and conceptual understanding was collected through pre-test and post-test. The questionnaires were used to collect data on spiritual attitudes and were analyzed qualitatively. The results showed that logic thinking-ability improves from no logic thinking to inductive-deductive logic thinking. The improvement of logic thinking abilities was in the medium category. Understanding the concept shifted from incompetent to conceptual understanding with improvement, in the medium category. The questionnaires analysis showed that the students got spiritual values related to the awareness of God believing behind the natural phenomena that impact on their spiritual attitudes. This study also tried to apply the results of pure science research to support learning activities. Based on the result of the research, it can be concluded that the learning process using interactive conceptual with visualization can improve logic thinking, conceptual comprehension, and spiritual attitude embeding.
