Kakao merupakan salah satu hasil bumi dibidang perkebunan. Perkebunan kakao dengan hasilnya yaitu biji dapat diolah menjadi bahan dasar tepung atau coklat. Keberadaan perkebunan ini tentu perlu mendapat dukungan teknologi kecerdasan buatan untuk membantu proses pensortiran secara modern jika dilakukan penerapan conveyer belt model pemetikan otomatis masa depan menggunakan drone pemetik buah. Pr...

Separating clods from potato tubers is one of the most challenging jobs in a potato harvester. Discriminating between potato tubers and clods is the first step in developing an automatic separation system on potato harvesters. In this study, an acoustic-based intelligent system was developed for high speed discriminating between potato tubers and clods. About 500 kg mixture of potato tubers and...

Biomass, as a renewable source of energy, can be used in many industries to reduce their dependence on fossil fuels. However, due to the significantly high and varied moisture content of biomass, its use has several drawbacks, such as low total efficiency and process instability. Drying biomass before combustion or gasification can eliminate these drawbacks. Besides these benefits, there ar...

The unbinding process of E2020 ((R,S)-1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]-methylpiperidine) leaving from the long active site gorge of Torpedo californica acetylcholinesterase (TcAChE) was studied by using steered molecular dynamics (SMD) simulations on a nanosecond scale with different velocities, and unbinding force profiles were obtained. Different from the unbinding of other AChE in...

High-Tc superconducting quantum interference device (SQUID) is an ultra-sensitive magnetic sensor. After the discovery of the high-Tc superconducting materials, the performance of the high-Tc SQUID has been improved and stabilized. One strong candidate for application is a detection system of magnetic foreign matters in industrial products. There is a possibility that ultra-small metallic forei...
