Marine Garbage Dredge Prototype for Coastal Area

Abstract

Activities carried out in coastal areas such as recreation, fishing activities, and transportation makes coastal regions have an essential role in life. However, activities carried out in the region often leave negative impacts, such as dumping trash directly into the sea. Coastal communities still carry out their activities to dispose of their waste now to the sea. The process of cleaning up marine litter in the coastal areas using heavy equipment is quite tricky. This is because the condition of buildings in the coastal area has the building with the concept of houses on stilts. The research has succeeded in making a marine garbage dredging using a conveyor system that is contained using a wireless joystick and can be well controlled within a radius of about 7 meters. The dredging is also equipped with a weight sensor (load cell) used to determine the load of garbage displayed on the 16 x 2 LCD. Garbage weight is stored in the SD card. The data stored on the SD card will show the time and load of garbage that has been transported by conveyor in an area.

Is contract arrangement source of income gain among parboiled rice stakeholders in Benin? A doubly robust analysis

“…They concluded that this new method of evaluating agricultural contracts is a tool to help managers and policy makers design CFAs that match the underlying transaction attributes, thereby improving the stability and efficiency of CFAs. The work of [ 12 ] explains that contract farming is a practice aimed at reducing the risk and uncertainty commonly done on agriculture. They notify that this form of agriculture is divided into two types which are contract production and market contract.…”

“…First, to our knowledge, this is the first study in Benin that focuses on both producers and processors by investigating jointly the driving factors of participation in contract and their effects on their income. Most of the previous studies focused separately on either the producers or the processors and mainly investigated the determinants of the participation in contract farming [ 9 , 10 , 11 , 12 ]. Second, to our knowledge very few studies have assessed the income effect of participation in contract farming using rigorous econometric methods.…”
