This project was created to sort bottles automatically. By specifying 3 types of bottles which are plastic bottles glass bottles and cans To help facilitate the separation of the bottles and then recycle the extracted bottles as needed. The organizer has studied the use of the Arduino program to control the operation of the sorting bottles according to the specified category. Studied the microcontroller system operation Control system And how to use the Arduino program The operating system is divided into 2 parts namely the metal detection sensor section And weight sensor and then send data to the sensor receiver Arduino And the sensor will detect the object all the time in the empty bottle compartment The results showed that the operation of the automatic bottle sorter system When throwing the bottle through the sensor compartment. The performance of the Arduino program that has been written to define the classification of the bottles. Have the percentage of work as specified by 90% and the error percentage of 10%

Thailand is an agricultural country. Most of the population consists of farmer. The rice is suitable to the climate of the country. And the main export of Thai is rice. The preparation of grain is also important.The farmer have to has an experience to choose the grain for growing the rice in farm. Good grian will give the high product. And good grain should completely free from contamination of disease and insect. Then it will be healthy seedlings. It is easy to harvest crops in a very high quality. Even it has good and high quality but it still has in impurities in the seed. Then the idea to create a project of sorting impurities from seeds. From the first it was built to help farmers to separate impurities such as grasses and husks. But the problem is the size of the maching is 140 x 150 x 160 cm which is larg and heavy then it makes the inconvenient to move. The preparation of the project is to develop an interest in sorting impurities in grain. The objective is to reduce the size to a smaller size than before. And increase the work more efficiency. The main aim is to sorting impurities in grain. Preparing the rice and put into the machin when power is opened. Rice will be flowing through the sieve which it works as a distribution and contamination. Then it will fail down into the sorting room. Impurities will be removed and the wind from the fan will blow the seeds. So we will get the good product and high quality. The results of the test. Wind is the best performance of the machine. Separating rice grains is 5.4 meters per second. The test of separating of the rice grains in 5 times and in the test of the 10 20 30 40 and 50 kg with a mixture of 10 percent of husk. the most effective of sorting rice is 10 kg. It can be isolated 99.30 percent with in 1.23 minutes.

In the procedure processes of Robusta coffee initial from bring the green coffee after dried and removed the outside shell and bring it to separating process. The sale price depends on the size of green coffee. If their size of still standard the sale price have been increased. Most of the separating process is majorly with the labor experience. Based on human experience the error with operating and working time is increased. In this reason we will study to the criteria of Robusta coffee for designing and creating the Robusta coffee bean separator machine for Robusta size standard testing. The separator machine consists of the three-layer cylindrical sieve set and the diameter of the layers was 4 6 and 7.5 mm. respectively. For the standardization of Robusta coffee bean is controlled by size of hole sieve. In this research considers to 4 importance parameters by the efficiency of sorting out standard of green coffee Specific Energy Consumption [SEC] and assessment way economic engineering. The result of research shows that the maximum efficiency of green coffee separating is 164.7 kg/hr under the condition of testing with 14.4 rpm at 4 angle incline. In term of standard it found that the machine can separated only for standard and smaller than standard size of green coffee and the maximum moistness are 9.9%. For the least Specific Energy Consumption [SEC] is 0.01631 MJ/kg and occur with the same condition of experiment. Based on this condition the Break-Even Point must be sorting out with 1070550 kilogram per year and Payback Period will occur at 3.598 years. However the quantity of separating or the efficiency of machine is mainly effect to Break-Even Point and Payback Period.
