Increasing the role of information systems / information technology through e-Learning media allows evaluated so as to know the needs that need to be developed and maintained its existence. For that, there needs to be a study to find out how much e-learning earmarking role in the learning process students in school. The research was done by using Unified Theory of Acceptance and Use of Technology (UTAUT) model that able to explain and predict the factors that significantly influence in the use of e-Learning at SMK Global Informatika Tangerang. The UTAUT model in this study was tested by validation process on the factors that significantly influence in the use of e-Learning done by using SEM analysis and AMOS software. The result of this research is that Effort Expectancy and Facilitating Condition have significant effect on Behavior Intention and Use Behavior. Thus the conclusion obtained is the e-Learning media accessed by students of SMK Global Informatika Tangerang is very easy to understand coupled with the availability of facilities that contribute to the progress of student learning. Abstrak Peningkatan peran sistem informasi/teknologi informasi melalui media e-Learning memungkinkan dievaluasi sehingga dapat mengetahui kebutuhan yang perlu dikembangkan dan tetap dipertahankan keberadaannya. Untuk itu, perlu adanya suatu kajian untuk mengetahui seberapa besar pemanfataan e-Learning berperan pada proses pembelajaran siswa di sekolah. Penelitian dilakukan dengan pendekatan model Unified Theory of Acceptance and Use of Technology (UTAUT) yang mampu menjelaskan serta memprediksi faktor-faktor yang signifikan berpengaruh dalam penggunaan e-Learning pada SMK Global Informatika Tangerang. Model UTAUT dalam penelitian ini diuji dengan proses validasi terhadap faktor-faktor yang signifikan berpengaruh dalam penggunaan e-Learning dilakukan dengan menggunakan analisis SEM dan software AMOS. Adapun hasil dari penelitian ini adalah bahwa faktor Effort Expectancy dan Facilitating Condition berpengaruh signifikan terhadap Behaviour Intention dan Use Behaviour. Dengan demikian kesimpulan yang diperoleh adalah media e-Learning yang diakses siswa SMK Global Informatika Tangerang sangat mudah untuk dipahami dibarengi juga adanya dukungan ketersediaan fasilitas-fasilitas yang memberikan kontribusi terhadap kemajuan pembelajaran siswa.
The most important issues in spray combustion science are how to understand the mechanism of the combustion of liquid fuel spray, especially in the flame-spread phenomenon. In spray combustion, combustion is the existence of the group is very important in order to obtain the stable combustion. Therefore, the flame spread among fuel droplets affects the occurrence of stable combustion in the spray combustion engine. This study was focused on phenomenon on diesel combustion engines. This research was conducted to study the behavior of flame spread rate of flame spread and limit the distance of bio-diesel liquid droplets. This research method was used experimental research. Microgravity condition was Obtained through the free fall tower with the height of the tower used is 6 m. Observed droplets suspended was placed on SiC fibers with different distance and droplet size 1 mm. This study observed Also the influence of the flame propagation direction of the burning droplet to the next burning droplets that lies in the direction and perpendicular to the direction of the flame propagation. The results showed that the bio-diesel fuel droplet Igniter (I) could burn next droplet (A)at a distance (S/d0) = 8.
Dalam bidang manufaktur, pemesinan CNC/CAM merupakan teknologi pemesinan yang paling berpotensi untuk dikembangkan menyesuaikan dengan revolusi industri 4.0. Penelitian ini dilakukan untuk melihat tingkat keterlaksanaan pembelajaran KI/KD CNC/CAM di SMK dan LPTK serta relevansinya terhadap kebutuhan industri. Penelitian dilaksanakan dengan triangulation mixed method design, yaitu desain penelitian campuran antara kualitatif dan kuantitatif yang dilaksanakan secara bersamaan. Penelitian kuantitatif dilaksanakan dengan desain survei menggunakan instrumen kuesioner yang hasilnya diolah dan disajikan secara deskriptif, sedangkan pendekatan kualitatif dilaksanakan dengan metode interview dan observasi partisipatif yang hasilnya disarikan dan diinterpretasikan untuk memperkuat temuan penelitian kuantitatif. Penelitian dilaksanakan pada SMK-SMK di Kota Surakarta yang menyelenggarakan Kompetensi Keahlian Teknik Pemesinan. Dari penelitian ini ditemukan bahwa jenis mesin, controller, dan software CAM bukan lah suatu permasalahan dalam link and match pembelajaran CNC/CAM, akan tetapi, yang menjadi kunci keselarasan adalah KI/KD pembelajaran. Penelitian juga menemukan bahwa berbagai KI/KD dalam bidang CNC sebagaimana yang diamanatkan dalam kurikulum telah terlaksana dengan baik dalam pembelajaran di SMK maupun LPTK. Penelitian ini juga mengkonfirmasi bahwa KI/KD bidang CNC/CAM antara LPTK, SMK, dan industri, saat ini pada level ‘sangat relevan’. Penelitian ini juga mengungkap bahwa LPTK dan SMK cenderung konsisten menyampaikan KI/KD sesuai amanat kurikulum, sedangkan industri cenderung ada KI/KD tertentu yang cenderung lebih dominan dibanding dengan KI/KD yang lain.
Conversion of palm starch waste biomass into energy sources through gasification process could be done to meet the energy requirement in palm noodle industry. This research used the Refuse Derived Fuel (RDF-5) based on the palm Starch waste. This is due to the how to overcome the solid waste around the home industry of noodle in Jawa Tengah. This study was conducted to determine the performance of up-draft gasifier with variations of air flow rate, i.e., 72 lpm, 95 lpm, and 123 lpm. The results showed that the variation of air flow rate has affected to the gasification product. The optimum LHV value occurred at 122 l/m air flow rate, where the LHV value increased with the increase of air flow rate, but after passing 122 l/m, the LHV value was continually decreasing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
