Sediment transport is the movement of sediment granular material/non cohesive by water flow. Sediment is carried by the flow of water constantly, which can be distinguished as floating sediment (suspended load) and bed load sediment. Sediment transport from upstream to down stream will affect some areas that experienced scour and deposition (sedimentation). This will cause a variety of problem shence it is needed to know the amount of sediment transport since it always moves with the flow.To minimize its negative effects, it is necessary to study the amount of sediment transport with homogeneous base material composed of sand and gravel. This study aimed to determine the effect of water discharge(Q) and the number of stream sediment transported (T) and to knowthe basic condition of the channel due to sediment transport after discharge flowed. The experiment was conducted at the glass channel of Laboratory of Hydrology/Hydraulics, Faculty of Engineering, University of Palangka Raya with dimensions of 400x10x25cm, while the selection of grain grading and inspection of the channel density of the base material such as sand and gravel carried out at the Laboratory of Soil Mechanics, Faculty of Engineering, University of Palangka Raya.The amount of discharge flowed varies with time and the experiment was performed 5 times for each channel base material. The results of the sediment transport studies on materials such as sand and gravel base shows that the greater the flow, the greater also the amount of sediment transported while the smaller debit amounts of sediment transported less. Sand diameter 0.43mm to0.58 mm transported more than the transported gravel with a diameter of2.40mm to 4.75mm, mostly gravel grain rolling and sliding just moves along the baseline. Basic conditions after a transport channel has changed from its original condition with the average basic channels 2.00cm thickness would appear to be a plane bed, washed-out dunes/transition, ripple and dunes.

Coconut shell is an organic waste (waste processing) of household or industrial use of coconut as the main raw material. Most usage of coconut shell is merely as a firewood which is a challenge to be able to take advantage of coconut shell optimally, when coconut shells can be proved technically as material / aggregate for concrete. It is expected to reduce the impact of environmental pollution then having alternative economic value for community. The study aims to determine what the optimum compressive strength of concrete resulting from the addition of coconut shell in the concrete mix. In this study, the coconut shell is broken down into fragments that are up to 20 mm used as an addition to the coarse aggregate mixed with fine aggregate, water and PPC cement type I of coarse sand brands. Percentage variation coconut shell applied in this study were 0%, 5%, 10%, 15% and 20%. Concrete mix design was using SNI 03-2834-2000. The test used a cylindrical specimen with a height of 30 cm, 15cm diameter with a sample of 10 cylinders for each variation of the addition of coconut shell, thus the total of 50 cylindrical specimen. Tests carried out at 14 and 28 days in the Laboratory of Building Engineering Study Program of the Faculty of Education University of Palangkaraya. The results showed the highest compressive strength of concrete that uses a mixture of 5% coconut shell in the amount of 23.66 MPa, while the compressive strength of normal concrete was resulting in the addition of 23.63 MPa compressive strength of concrete of 0.12% of normal concrete. The compressive strength of concrete on the coconut shell mixture of 10% was amounting to 19.72 MPa with a decrease of 16.54% of the compressive strength of normal concrete, shells 15% ie a decrease of 12.11 MPa to 48.75% of the compressive strength of normal concrete, shells 20% and amounting to 12.51 MPa to 47.05 decline of normal compressive strength of concrete with compressive strength forecast 28 days. The addition of coconut shell was opposite to the concrete mix increasing the strength of concrete for the addition of 5% by weight of coconut shell coconut. Shell addition of coarse aggregate in excess (over 5%) was causing the compressive strength of concrete will decrease.
