One of the reasons for the poor quality of palm oil in Indonesia is because of the separation system of processing method is processed manually. In this research, the proposed solution to overcome the problem is by applying the automatic separation system by using microcontroller. The maturity of the fruit will be determined from the image that taken by a camera. The reading of the camera image will be processed in a microcontroller which will move the separator arms so that the fruit will be separated based on the level of maturity. This system is designed to work continuously by placing the palm fruit over a conveyor belt mechanism. With this automation method, the separation process of fruit is no longer depends on the ability of humans manually and more importantly it can take place continuously.

As many other cities in the world, DKI Jakarta faces serious problems in the flood. In rainy season, common flooding is caused by several factors as follows: lowland areas in the northern part of Jakarta below sea level, urbanization rate, irregular population density, river pollution, slum neighborhood where scattered rubbish where quickly provoke the flood to stagnate and increase rather than receding. This paper studied on rivers pollution in DKI Jakarta. It was founded that water quality from 13 rivers in DKI Jakarta was at a critical level. The lack of sanitation systems in residential areas around rivers has highly contributed to pollute the rivers. It was 96 percent of the water is badly polluted. Therefore river water in DKI Jakarta can be harmful to health if consumed by the community.

Friction welding is a solid-state welding without the use of filler metal by using pressure method where by two workpieces to be connected. It is placed in contact and regulated relative motion in pressure, so that on the contact surface being heat (close to the metal liquid point), which form the metal connection. A friction welding machine in the laboratory of technology production of the University of Riau has some disadvantages, namely the electric motor as a driver head stock stems that are often damaged due to overheating such as excessive during welding. Thus was interfering with the welding process due to damage to the electric motor. Therefore, this paper purpose is carried out the development of friction welding tool by using flywheel. The Flywheel stores energy during high engine speed, and passes it during low engine speeds to produce a steady turn. In this study used three flywheels with a diameter of 250 mm, which each thick of 10 mm, 20 mm and 30 mm. From the test is obtained the value of the average tensile strength on each flywheel that is 522.736 MPa, 510.648 MPa and 531.79 Mpa.
