Abstract

In general, traditional farmers still use the manual method which requires a large number of workers and takes longer for one hectare. With this mechanization, it is hoped that the time and cost at harvest will be faster and cheaper. It is hoped that this harvester can not only be used on one type of grass stalks plant (eg. rice) but can also be used for other types of grass stalks plants (lemongrass, sticky rice, straw). This paper produces a design using Inventor 3D to describe a mechanization system for harvesting grass stalks using a circular harvester. The crucial analysis carried out on the carrier, focuses on three things, namely the estimation of power system requirements, estimation of harvest capacity and system stability. Fits the speed-adjusting lever and the lever adjusts the height of the cutter. In its application can be used on wet land or dry land. The conclusion from the calculation is that the driving force is sufficient to move the body and cutting blades, the design capacity exceeds twice that of the manual method, and in practice the body is still stable when passing through land with an elevation of 30 degrees.

Abstract

CO2 Dispersion Consequences Study using 3D CFD method in a CCUS facility Abstract    Carbon Capture Utilization and Storage (CCUS) is a method and technology for CO2 gas injection that enables the capture and storage of CO2 underground.  The aim is the CO2 emission reduction into the atmosphere as well as enhancing oil/gas/heat recovery. Unlike their counterparts in USA and Europe, however, the CCUS technology in China is not yet mature or still at a pilot scale. Given the large quantities and flow rates which will be used for CCUS, consequently, major releases could produce significant hazard ranges at concentration high enough to have toxic effects. This paper focuses on the consequence of CO2 releases to the neighbourhood or environment which varies in elevations to study the effect to the varied ground levels from the release points to the extent of CO2 dispersion. The effect of large equipment to the CO2 concentration extents is also discussed.
