Proanthocyanidin extraction for antioxidant material from intact red sorghum grains in agitated vessel had been investigated. The optimization and the appropriate kinetic evaluation were useful to conduct the engineering design of the developed process. Concentrations of the proanthocyanidin compounds in the aqueous extract were affected by the agi...

Tracking antenna system dalam penggunaan set top box DVB-T2 adalah teknologi tepat guna yang dapat memudahkan pengguna dalam mendapatkan kualitas video yang optimal. Parameter input yang handal adalah salah satu syarat dalam realisasi tracking antenna system. Pada penelitian ini mengusulkan level luminansi pada sinyal analog CVBS sebagai parameter...

Real-time VQA (Video Quality Assessment) is an important part in the effort to build tracking antenna system especially for analog TV. In this case, VQA must work in real-time to assess the video clarity level. VQA assessment results are valuable information for the decision-making process. Thus, the antenna can rotate automatically looking for the...

Analog terrestrial TV is still a popular choice for urban societies although the migration to digital system has already begun. Video quality of analog TV was heavily influenced by performance of the antenna. Most users prefer to use indoor antenna due to its simplicity. The disadvantage of this type of antenna is the users may need to change the a...

Teaching and learning process of natural science subjects includes aspects of: knowledge, skill, and thinking competence. Teachers did not implement the teaching activity which emphasize on thinking and conceptual understanding process because of limited time to make teaching and learning set which can train students’ creative thinking and conceptu...

The objective of this research to produced learning materials were valid, practical, and effective to improved student’s conceptual understanding. The development of learning material used the ADDIE (Analyze, Design, Develop, Implement, and Evaluate) model and was tried out at VIII-A and VIII-B on SMP Negeri 1 Bandung Tulungagung with One Group Pre...
