Abstract

Bolt extension as link which do not destroy connective by component at process unload tide used many in so many industrial area like at bridge construction, building construction and various appliance of engine tool. Usage of amount 3 (bolt fruit three) at 5 (standard hole five) at one particular extension construction can be seen at tacking on two plate with bevel form at building roof construction. If usage more at one particular construction extension hence will have an in with wide of section, apart between hole at each bolt as well as its esthetics value. Formation arrange situation an bolt extension at one particular construction very having an effect on to failure of extension construction, is in this case done conducted by examination to an extension construction by 3 bolt fruit at 10 position differ from the target of searching optimal position in accepting style shift at bolt extension construction used by bolt is galvanic type have full of thread to. Is later got by tension value shift at each bolt and got by optimal position (strong position) and weak position from 10 existing position in accepting style shift [at] extension construction. Optimal position in this experiments are position 2 and 4. The position not optimal is position 6. Keywords: fracture surface, bolt , optimal position of bolt, deformation.

Abstract

Empty Fruit Bunches (EFB) are one of the solid wastes produced by the palm oil industry. One of the uses of EFB is as a raw material for making alternative briquettes to overcome dependence on fossil energy. In this research, the utilization of natural waste empty fruit bunches and pine bark which is processed into powder as an added material is an innovation to obtain the output of biomass briquettes for toughness and ignition quality. The addition of a certain amount of pine bark powder is an added function to see the quality of combustion. In the process of making bio-briquettes, the binder material is needed so that the briquettes are not easily crushed by 15% and the powder composition is 10%, 15%, and 20%. The tests carried out on the sample are drop test according to the ASTM D 440-86 R02 standard, and an ignition test to obtain the ash content produced from the combustion process. The results showed, at the composition of 20/15%, the ignition quality of the briquettes was higher in volume compared to the ignition of briquettes at the composition of 10/15% and 15/15%, and resulted in smoother and more uniform burning ash. On the other hand, in this composition too, the percentage of damaged briquette fibers during the drop test is 0.09%.

Abstract

Sand is the base ingredient in the development process. In addition, the material cannot be separated sand use in the industrial world. Often in industrial buildings and workers needed sand material that has been processed. Sand material is usually still mixed with rocks or gravel. To get fine sand material, do the sifting process. The sieving process is carried out in order to get ready for the sand used in the process. The design of this sand sifter tools will provide convenience and a better process when compared with the work done traditionally. Benefits of making the application of automatic sand sieving machine can help the construction workers, especially in the process of building the sand processing to several functionality and usability. And can be used to produce maximum results in conditions that are not limited in the field. The purpose of making sand sifter tools this automated system is to ease the work in process and streamline the shifting sands of time, economic and workforce. The process of making this tool consists of four main processes, manufacture sifter, frame and hopper manufacture, manufacture of other supporting components, and assembly of all components. From the results of tests and experiments, that for 20 kg of the starting material that contains sand and stone (gravel) is processed only takes approximately 25 seconds to produce three types of the filter sand and stone as well. In general, the innovation of this tool enabled us to increase production of larger sieve in a short time, for development work on a large scale; this tool is suitable for generating a large amount of production that would be more economical in terms of time and cost.
