Abstract

Pneumatics has a reat role in modern industries. Actually, this branch of knowlesge can be applied not only in industrial sectors. This control systen can be used in many aspects which apply the mobilicing and controlling activities, such as the electric control system and hydrolic control system. Based on this phenomena. The pneumatics can be used to open and to close the shifting door. For that necessary to achieve basic knowledge about is science which includes several aspects, for example, jource of motor, symbol and function of pneumatic components, air flow diagram, designing diagram of control series as well as its mechanisin. In order to avoid that door closes directly while its opening process is reaching maximal point, it is very useful in delaying t;lhe closing process of that door for several periods. That components is well known as the delaying valves. Opening and closing systems of a shifting door can be controlled from two controlling sides : from inside and outside of that door.

Abstract

Raffia rope is very popular because of its many uses, in other words it is a versatile tool. In general, raffia ropes are widely used for various matters such as business in agriculture, as a binder, as a decoration for crafts, as hangers for clothes, sewing sacks, as reinforcement materials, and many others. Raffia straps are available in the form of rolls. At this time, there are still many processes of rolling raffia still using manual methods such as direct hand rolling or using traditional methods that still use a lot of human power so that it is considered ineffective and inefficient. Because there is still a lot of traditional process of rolling the rope or using hands, the idea arises to make a raffia rope rolling machine using a motorbike and transmission. Technically appropriate technology is a bridge between traditional technology and advanced technology, therefore socio-cultural and economic aspects are also dimensions that must be taken into account in managing appropriate technology. From the desired goals, appropriate technology must apply methods that are resource-efficient, easy to maintain, and have minimal minimalistic impact. The aim of this research is to design, make and test rapia rope rollers so that they are suitable to be used to help facilitate the work of the community in the process of rolling rapia. From the results of design design. From the results of the testing obtained the tool is able to produce rolls as much as an average of 58 rolls per hour
