<![CDATA[In developing countries the necessity and the possibilities to manufacture machines locally are inc!easing. Often be necessary equipment, machines, material and the skilled labour as well as technical staff are available, but what is missing is the information and the know-how. One category of machines used to harness walet power and which can be produced locally, are water turbines. In some countries there is an established tradition in the production, installing and running of small water mills. Often these are units with simple vertical axis wheels or are large water wheels. For example, one country with experience on vertical axis water wheels.This research summarizes the simple calculations for designing a Pelton turbine with a head of water falling of 1130 m, with a discharge of Q = 28.5 m3/s, so that based on the calculations, a power of P = 288 MW is obtained.]]>

<![CDATA[The reinforcing composition in hybrid composite can affect the material properties. Kenaf fiber (Hibiscus Cannabinus L.) can be used as a reinforcement for hybrid composites with high advantage. Calcium carbonate serves as a reinforcement for composite materials and was useful for increasing stiffness. The purpose of this study was to analyze the effect of variations in the composition of the addition of kenaf fiber and CaCO3 powder on the flexural strength and water absorption properties of the calcium carbonate reinforced kenaf fibers/polyester hybrid composites (PTJ/SK/CaCO3) made by hand layup method. Hybrid composites were made with various compositions of CaCO3 (0%, 2.5%, 5%, 10%, and 20% by weight). The results showed that the PTJ/SK/CaCO3 (5%wt) hybrid composite had the highest flexural strength with a value of 74.87 MPa. The increase in the amount of CaCO3 powder composition showed a decrease in the water absorption of the PTJ/SK/CaCO3 hybrid composite.]]>

<![CDATA[Hardenability is the ability of a material to be hardened to a certain depth by means of heat treatment to formmartensite in the cooling process to achieve a certain hardness. One of the hardenability testing methods is theJominy Test. The specimen is heated at the specified temperature, then cooled by spraying water at one end. Aftertesting with the Jominy test apparatus, its hardness was measured using the hardness test equipment.The testingof Jominy is based on ASTM standard A255. Testing using specimens with a length of 100 mm, diameter25.4 mm as much as 9 pieces. Hardness is measured by the Rockwell Hardness Test method. The test result onspecimen 1 with a final temperature of 700 °c resulted in an average hardness value of 45.51 HRB, on specimen9 with a final temperature of 1100 °c amounting to 47.32 HRB. The higher the end temperature of the heating,the hardness value produced will be relatively higher. The highest average hardness value is in specimen 7 witha heating temperature of 1000 °c by 47.48 HRB.]]>

<![CDATA[Low carbon steel has a wide use in the construction sector and is classified into steel that can be processed by machinery (machinery steel). The salient disadvantage of this material is the type of failure in the form of chipping, and breaking. The purpose of this study was to determine the effect of the addition of belian and acacia wood charcoal on low carbon steel. This solid carburizing process uses a mixture of belian wood charcoal with calcium carbonate and acacia wood charcoal with calcium carbonate, and heattreatment at a temperature of 900oC, holding time of 30 minutes followed by quenching, with the Rockwell hardness test method. The test results show that the hardness of carbon steel that undergoes treatment is higher when compared to raw material of low carbon steel = 50.34HRB, where carburizing with acacia wood charcoal = 50.5HRB with a lower value when compared to belian wood charcoal = 50.94HRB. Judging from these results, the solid carburizing process with different types of charcoal will increase the hardness of low carbon steels.]]>
