Abstract

Concrete is one of construction material that has been used widely for many years.The advantages of using concrete as contruction materials are it has high compressive strength,easy to be molded, no need professional labours and the constituent materials of concrete arecheap and easy to get. Beside of those advantages, concrete also has disadvantage such as haslow tensile strength. Its tensile strength is only about 10% from its compressive strength. Manyprevious research has been conducted to increase the tensile strength of concrete. In late 1960s,fiber concrete has been researched to be the solution to increase the tensile strength of concrete.Types of fiber concrete are steel fiber, glass fiber, synthetic fiber and natural fiber. Naturalfiber concrete such as bamboo has low manufacturing cost than the other types of fiber. Theaimed of this research is to investigate the influence of bamboo fiber concrete on the tensilestrength and the compressive strength of concrete. The percentage of bamboo fiber were variedfrom 0%, 1%, 2% and 3% by cement material. The test results showed that bamboo fiberconcrete increase the tensile strength test and compressive strength test result. The highesttensile strength was 12,4 MPa in 28 days obtained by mixture that contained 2% of bamboofiber. The highest compressive strength concrete was 28,3 MPa in 28 days from the mixtureswith 1% of bamboo fiber.Keywords: concrete, fiber concrete, bamboo fiber concrete, compressive strength, tensilestrength

Abstract

Energy crisis engulfing the world recently has become people’s concern in finding new energy sources which are cheaper and available in the large numbers. The alternative is energy source to drive a turbine. In this case, water will gradually change its potential energy to be kinetic energy which then becomes mechanic energy to move turbine shaft. In this way, the yielded power source can drive other tools needed such as generator which produces electric current. The turbine used in the research was pelton turbine with inverter. The comparison of various lamp power i.e.3,5,9, and 12 watts was analyzed. The data collection was conducted on variables of water capacity, voltage, electric curent, electric power, and hydraulic power.

Abstract

Concrete is important engineering material, expensive construction can be caused by increasing cost of concrete. In recent years, concrete production has increased which means consumption of coarse aggregate also increased. Natural coarse aggregate is gravel. Due to the growth in the construction industry, the demand for gravel is increasing rapidly, therefore gravel is expensive. Constructions companies which are close to Sampang are used to using limestone from Sampang as partial replacement of coarse aggregate for construction which are cheaper and greater available than gravel in order to reduce concrete cost. In this case there is a need to study the concrete with limestone from Sampang as coarse aggregate in order to get better understanding of limestone in concrete mixes. The aim of this research is to investigate the compressive strength of the concrete in which limestone from Sampang was used as coarse aggregate is partially or completely replaced.  The coarse aggregate was replaced with  0%, 25%, 50%, 75% , 100% by limestone from Sampang, respectively. The compressive strengths of concrete speciemens for respective mix proportions were tested at 3, 7, 14 and 28 days of water curing. In addition the source aggregate properties were considered in this research : Los Angeles abrasion, absorption and spesific gravity for coarse aggregates and fine aggregate. The result of this investigation showed with the increase in the percentage of limestone from Sampang replacement in concrete, the compressive strength of the limestone from Sampang significantly increased.Keywords: concrete, coarse aggregate, limestone, compressive strength
