Abstract

The use of composite materials in Indonesia, as a nonmetal alternative material has begun to increase. Composite use has grown from water tanks from fiberglass materials, household appliances, children's toys, sports equipment, furniture/interior design to automotive components and aircraft. Many of the advantages of this composite material include hand, strong, anti-corrosion, finely tuned finish. Its mild nature has a direct impact on energy savings. The prospect of composite materials as a non-metal alternative material is rapidly growing and its use. Various types of reinforce used can be influenced by the prices available, so seek alternatives as a commonly used glass fiber substitute woven rowing. The substitute used is a sack of gourds of the same kind as woven rowing, from which the same type of fiber is tried to find its strength by undergoing a pull test. And as a result of the test the mateial can know its power.

Abstract

Steering system is a system control unit that is used for deflecting the direction of motion straight into to the left or to the right in accordance with the will of the operator. At 785-7 HD unit using the steering system type full hydraulic steering valve, where steering valve serves as a directional control valve to direct the oil flow at the time of engine working (pump work), whereas when the engine died steering valve will serve as a hand pump and directional control valve. Abnormaly steering wheel because there is a scratch on spool demand valve causing internal leakage in the demand valve so oil pressure which served as the pilot sensing to move the spool valve is a pressure demand would drop because there is a leak and could not afford to drive the spool until the full open- as a result the oil flow from the steering pump cannot be fully prioritized to steering valve to be forwarded to the steering cylinder.

Abstract

One of the main factors in securing an electric power system is the earthing system. The earthing system in the generating unit is closely related to the switchyard. Switchyard earthing system design is done by adjusting the grid distance and ground rod length to get the most optimal quality and cost combination. The definition of optimal conditions in this case is limited to circumstances where there is a combination of quality that does not exceed the technical tolerance threshold and has cost efficiency. The design of the switchyard earthing system was taken as a case study. Technical standards are carried out based on IEEE Std 80 - 2000. Calculations for obtaining technical parameters and costs are carried out one-by-one in the range of grid spacing and length of certain ground rods to determine the optimum point using MATLAB-GUI as a programming tool and MATLAB R2011a as a tool mathematical computing. Calculation results and analysis concluded that the grid distance of 23 m and the length of the 6 m ground rod is the best choice in the optimization of this earthing system by meeting the safety quality criteria for earth resistance is Rg = 0.13806 Ω less than 0.5 Ω with a minimum cost of Rp. 1,220,104,730.

Abstract

Quality is a factor that determines the success of a product penetrate the market, in addition to other major factors such as price and service. Quality products will have great competitiveness and high quality level. Products produced from extracts of natural ingredients, one product is Black Tea extract. To maintain customer satisfaction, the company tries to emphasize the value of DPU that occurs. This study aims to analyze the defect reject from the production of Black Tea Extract for a year using SIPOC diagram (Supplier Input Process Output) and Pareto diagram. Result of research is total production during that period equal to 358 batch x 300 Kg = 107400 kg, total reject of 78 batch x 300 kg = 23400 kg, with total reject for Black tea extract 21,79%. Can be known in the process of Black Tea extract reject largest in reject brix out of spec for 93.67% and Reject Tannin out of spec 6.33%. So it can be concluded that the dominant reject of the production process for black tea extract products is reject brix out of spec.

Abstract

The company's Palm Oil Mill (PKS) that produces the main products are Crude Palm Oil (CPO), Palm Kernel Oil (PKO) while the byproducts are solid waste in the form of fiber, shells, and Empty Fruit Bunches. Palm oil mill solid waste in the form of fiber and shells has the potential to become fuel for Steam Power Plants (PLTU). Fresh Fruit Bunch (TBS) Material Balance from Palm Oil Mill production output: Shells: 7%, Fiber: 13%, Empty bunches: 22% which can generate the total available Heat Calor of 28.936×106 Kcal / hour, and Total Total Power can be generated as much as 3.9 MW from the Palm Oil Mill Solid Waste which produces a thoughtput of 50 Tons / hour.
