Abstract

Strontium titanate (SrTiO3) film was successfully deposited on a silicon substrate by using a pulsed-laser ablation deposition (PLAD) technique. The optimum temperature is 600o C. The electrical properties measurement was metal-oxide-semiconductor capacitor. The film exhibits good insulating property at room temperature. The fixed charge density and leakage current density were also calculated. The results show that the films have promising applications as alternative gate dielectrics.

Abstract

Microcrystalline hydrogenated silicon thin films have been grown on corning 7059 by using Hot Wire Plasma Enhanced Chemical Vapor Deposition (PECVD) system. Silane gas dilute in hydrogen gas (SiH4: H2 = 1 : 10 ) used as gas source. The effect substrate temperatures on deposition rate, optical, electrical and structural properties were analyzed. The deposition rate was varied from 3.22-5.24 µm/hour at temperature 175-275o C, SiH4 flow rate of 70 sccm, and filament temperature ~ 1000oC. The optical band gap varied from 1.13-1.44 eV at substrate temperature of 175-275. The Result XRD characterization of µc-Si: H thin film was grown at 275o C shows , , and orientation. Dark conductivities vary from 10-6-10-4 S/cm The Dark conductivity of µc-Si: H is higher than a-Si: H thin film. This result shows that µc-Si: H thin film is possible for p-i-n solar cells device application.

Abstract

Amorphous ceria (CeO2) thin films were deposited on a silicon (100) substrate by using a pulsed-laser ablation deposition (PLAD) technique. The substrate temperature was varied from 600 to 7000 C and the ambient was a pure oxygen gas at the pressure of 100 mTorr. It was found that the growth rate is 17.5 nm/min. Low fixed-charge densities (1011/cm2) and high resistivies (109-1012 Ω cm) of the CeO2 thin films indicate that the films could be used for oxide layer of metal-oxide-semiconductor (MOS) capacitors. Electron conduction mechanism in the CeO2 thin films is ohmic at voltages below 1 V while that at voltages above 1 V are due to quantum tunneling process.

Abstract

The purpose of this research was to study distribution and abundance of (shrubs, herbs, and rumput) under the three stands,i.e. Pinus mercusii, Acacia auriculiformis and Eucalyptus alba and environmental factors influencing them in Gama Girimandiri Forest. Data were collected in April-May 2011, using square plots. Plots were located in three locations by followinga stratified random sampling method. We administered 10 repetitions, and plot size 5x5 m for shrubs and herbs, and 1X1 m forgrass. The species found in each stand were identified and calculated for their density, frequency, domination, importantvalue, diversity index, and those parameters’ correlation with the measured environmental factors. The study shows that 59species of herbs and shrubs, and 12 species of grass. In the three stands, it could be shown various domination of grass,meanwhile there is no dominant species at the level of herbs and shrubs. The highest density, measured by diversity index,was observed at the stand of Pinus (3,13), followed by Acacia (3,12) and Eucalyptus (2,8). The distribution and density ofMemecylon sp and Oplismenus burmanni were observed at their highest value under the stand of Pinus, Lantana camaraLinn (37.2). At the same fashion, Paspalum conjugatum (58.3) does under the stand of Acacia, and Desmodium triflorum(64,2) and Ischaemum magnum (122) under Eucalyptus. Lantana camara could always be found under the three stands, ithad high important value, categorized as strategy species and invasive. Light density and pH significantly influenced thediversity index of shrubs and herbs. In addition, only soil temperature gave an effect to grass.

Abstract

Penelitian ini bertujuan untuk mengetahui gaya belajar yang dimiliki oleh siswa berprestasi mata pelajaran fisika di SMA Al-Azhaar Palu. Gaya belajar adalah cara yang konstan yang dilakukan oleh seorang murid dalam memecahkan soal. Gaya belajar yang diungkapkan oleh David Kolb akan membentuk empat kombinasi kuadran gaya belajar yaitu gaya belajar Diverger, Assimilator, Converger dan Accomodator. Penelitian ini merupakan penelitian deskriptif kualitatif. Responden dalam penelitian ini adalah siswa kelas XI MIA SMA Al-Azhaar Palu yang berprestasi dan mendapatkan nilai tertinggi pada mata pelajaran fisika Tahun Ajaran 2018/2019 yang berjumlah 9 orang.  Adapun teknik pengumpulan data yang digunakan berupa angket yang terdiri dari 24 pernyataan yang diisi oleh siswa dengan cara memberikan skor 1-4. Dari hasil penelitian ini dapat disimpulkan bahwa Gaya belajar siswa berprestasi mata pelajaran fisika di kelas XI MIA 1, 2 dan 3 SMA Al-Azhaar Palu lebih dominan pada gaya belajar accomodator (Kuadran IV) yang merupakan kombinasi antara kutub perasaan dengan tindakan dengan persentase sebesar 82,64%.

Abstract

This research was purposed to describe the way of the students' thinking in completing the vector-based test by physical context. The instrument of this research consisted of the respondent selection test (TSR), logical test with thinking-aloud (TA), and interview guidance. Respondents of this research were six students in one of the senior high school in Palu. Collecting data was held by applying a thinking-aloud (TA) and interview which recorded by using a video camera. The interview was conducted to find out supporting data in analyzing the result of thinking-aloud (TA) data. The analyzing data of the way of students' thinking can be seen from every step of their respondents in completing the test by using physical context. Generally, there are two thinking models that are deductive thinking and inductive thinking. In the analysis of the results of TA and interviews, obtained that respondents are more dominant used of deductive thinking in completing the test than inductive thinking. It was influenced by the teacher's method in providing the test when the teaching-learning process and the students' usage in completing the test.
