Abstract

Thin film of microcrystal silicon hydrogenated (μC-Si:H) p-type has been successfully grown in a hot-wire plasma enhanced chemical vapor deposition (HW-PECVD) by using silane gas (SiH4) and diborane (B2H6) diluted in 10% H2 respectively as gas resources. The resulted thin film have optical band gap decreased from 1.88 eV to 1.50 eV as the dopant concentration increased from 0.50% to 0.20% on filament voltage of 4.5 volt and RF power of 100 watt. Dark and photo conductivities of the film were found significantly high, in the order of 10-8-10-6 Scm-1 and 10-5-10-3 Scm-1 respectively. The conductivity is two order higher than thin film a-Si:H p-type grown using PECVD technique without hot-wire. It is concluded that the thin film produced in this study is suitable for solar cell application and other microelectronic devices

Abstract

Persamaan Navier-Stokes memiliki bentuk persamaan diferensial parsial non-linier orde dua yang menerangkan pergerakan dari suatu fluida. Persamaan ini menjelaskan keseimbangan gaya-gaya yang bekerja pada fluida yaitu gaya-gaya benda dan gaya-gaya permukaan. Dalam studi ini, kasus yang ditinjau adalah aliran fluida laminar pada pipa tidak horizontal. Penyelesaian persamaan Navier-Stokes dilakukan secara teoretik. Dengan mengubah persamaan dalam bentuk koordinat polar serta mengintegrasikan secara langsung, maka diperoleh kecepatan rata-rata fluida, laju aliran volume fluida, serta laju aliran massa fluida pada pipa tidak horizontal.Kata Kunci : Persamaan Navier-Stokes, Pipa Tidak Horizontal, Kecepatan Rata-rata

Abstract

Calcium carbonate (Ca(CO3)) made from limestone obtained in Tellu Limpoe Village Suppa District with the calcination process for 4 hours at temperature variations 550oC, 650oC, and 750oC have been characterized. The higher temperature, the lower percentage of calcite and phase formed more and more. Evident from the result of the characterization of Ca(CO3) calcination with phase shows the XRD obtained calcite each temperature i.e. 98.8%, 92.2% and 84.0% and also the formation of calcium oxide (CaO) phase at the calcination temperature 750oC due to limestone undergoing decomposition by heat energy. The based on analysis of SEM, morphology of Ca(CO3) resembles a cube but the particles size of the uneven and irregular due to the presence of pollutant factors. As for the results of the analysis of the calcium content acquired EDS in the limestone is quite high. Than results of the study it was concluded that limestone has a high purity level because of other chemical elements less than 15%. Telah dilakukan karakterisasi kalsium karbonat (Ca(CO3)) dari batu kapur yang diperoleh di Kelurahan Tellu Limpoe Kecamatan Suppa dengan proses kalsinasi selama 4 jam pada variasi suhu 550oC, 650oC, dan 750oC. Semakin tinggi suhu, kadar kalsit semakin rendah dan fasa yang terbentuk semakin banyak. Terbukti dari karakterisasi Ca(CO3) hasil kalsinasi dengan XRD menunjukkan fasa calcite yang diperoleh untuk masing-masing suhu yaitu 98.8%, 92.2% dan 84.0% juga terbentuknya fasa CaO pada suhu kalsinasi 750oC akibat batu kapur mengalami dekomposisi oleh adanya energi panas. Kemudian berdasarkan analisis SEM, morfologi Ca(CO3) menyerupai kubus namun ukuran partikelnya tidak merata dan tidak beraturan disebabkan adanya faktor pengotor. Sedangkan untuk hasil analisis EDS diperoleh kandungan kalsium yang terdapat dalam batu kapur cukup tinggi. Dari hasil penelitian disimpulkan bahwa batu kapur memiliki tingkat kemurnian yang tinggi dikarenakan unsur bahan kimia lain kurang dari 15%.Kata Kunci:  batu kapur, kalsium karbonat (Ca(CO)3), kalsinasi

Abstract

This study aimed to analyze the effect of IS Success Model variable on Edmodo's e-learning user satisfaction partially, both directly and indirectly through the TAM variable. This research was conducted through an ex-post-facto approach to undergraduate students. Data collection instruments used questionnaire and observation. The questionnaire was developed from the technology acceptance model (TAM) and information system (IS) success model. The collected data were analyzed through descriptive statistics and path analysis using IBM SPSS 20 program. The results showed that the three core variables of the IS Success model directly had a significant effect on the two core variables of TAM, and the two core variables of TAM directly affected user satisfaction. Indirectly, the three core variables of IS Success model had a significant effect on user satisfaction through the two core variables of TAM. Service Quality, also, to provide a more significant direct effect on perceived usefulness, also indirectly influenced user satisfaction through perceived usefulness. Perceived ease of use had more significant direct and indirect effects through perceived usefulness on Edmodo e-learning user satisfaction.
