Abstract

 This Sincetific work about box underpass design has a purpose to design box underpass and design jacking force for box underpass indtallation. The method of box underpass designing is ultimate design method. Box underpass designed for a 60 cm thick for top slab, foundation slab, and wall plates. And used K-500 quality of concrete, and BjTD 40 quality of reinforcement steel. In this case, structural analysis performed using moment distribution method. Moment, shear, and axial force is used to calculate the reinforcement and control of serviceability. For top slab, main bar used is D36 – 200, while support bar used is D22 – 300. For the foundation slab, main bar used is D36 - 250, while support bar used is D22 – 350. For the wall plate, the main bar used was D32 - 200, support bar used is D19 - 350, while the shear bar used is D19 - 500. For one box underpass installation with 9,3 m length into the soil needed jacking force greater than 8190,185 kN. And for add one span box underpass, required additional jacking force around 4726,583kN. Keywords: Box Underpass, Concrete, Reinforcement, Jacking Force

Abstract

Hydrocyclone is a tool used for the separation of solid materials in the carrier medium by utilizing the generated vortex effect of centrifugal force. Hydrocyclone consists of a vertical cylindrical portion with a funnel-shaped bottom part, inlet doors on the upper side, the door at the bottom of the underflow and overflow at the top of the door. In this study will be known how widespread the effect of head and underflow of the water in the sediment separation efficiency hydrocyclone apparatus. Variations on hydrocyclone efficiency of 94.1% due to the broad head and underflow and the remaining 5.9% is influenced by other things that can not be explained by existing variables. Between the head and sediment hydrocyclone separation efficiency are unidirectional relationship but weak. Wide underflow with sediment hydrocyclone separation efficiency occurs negative correlation is very strong and has a closeness, while the head and broad underflow there is no relationship. The best analysis model in predicting the dependent variable (sediment hydrocyclone separation efficiency) with the influence of the independent variables (head and broad underflow) is a multiple linear regression model with a predictive equation Y = 0612 + 0915 head - spacious 0646 underflow. Prediction efficiency hydrocyclone separation highest sediment that occurs at 98 746% with the results of laboratory studies of 99 781%, which is at the head of 50% and 13% of the underflow broad inlet door. Key words: hydrocyclone, head, broad underflow, the separation efficiency of the sediment, and water

Abstract

The development of the tourist area on the island tidung is a step to be able to improve tourist facilities existing in Tidung Island. Tidung island as a mainstay in the tourist area of the Thousand Islands is currently a resident of Jakarta tourist destination. With the increasing number of tourists to the island Tidung it is necessary to the development of the region in accordance with the existing potential in Tidung itself. Development of water in the tourist area Tidung a solution to be able to reorganize the region Tidung which has the natural beauty of the beauty of the sea and its contents. Key Words: Seribu archipelago, Development, Tidung Island, Water tourism
