Abstract

This study aims to investigate water domestic demand of people living in coastal area of Bandar Lampung City. The location of the study is in the Sukaraja area, Bumi Waras Sub-district, Bandar Lampung City. Data mining of household water demand is undertaken by using questionnaire to 65 households. It is indicated from the survey that every household averagely consits of 4 persons. Everry person spends about IDR 368 for 103.4 l of water domestic in daily basis. Daily water domestic demand of the people in the are study is quite different from the standard daily water domestic demand percapita. This deviation is due to the differences in the aspect of social and economy between the people in the are study and ordinary people

Abstract

Every light or heavy load construction recquires a supportive foundation, the foundation must be calculated to be able to guarantee the stability of the building to its own weight, building loads and external forces. Pillar foundation is used as a building foundation when the land under the building does not provide sufficient carrying capacity to carry the weight of the building and its load. This research was carried out on one of the bridges on the Trans Sumatra Toll Road. A pillar foundation is used to the toll road project. The purpose of this research is to determine the bearing capacity of the foundation on the pier and abutment from the results of load on the upper construction. Based on the results of the carrying capacity of abutment is obtained 60 cm diameter of pile with 6 pieces, and the bridge’s pillar is 60 cm of pile 15 pieces. While the main reinforcement diameter is 22 mm as much as 6 pieces, with Ø10 strap and 250 mm distance.  Keywords: Foundation, Pillar, Pile, Pile Carrying Capacity

Abstract

Provinsi Lampung merupakan gerbang Pulau Sumatera, sehingga pembangunan infrastruktur saat ini semakin berkembang pesat. Pembangunan konstruksi tersebut sangat erat berkaitan dengan daya dukung tanah karena tanah merupakan material yang berperanan penting dalam menopang suatu konstruksi. Untuk mengetahui kekuatan daya dukung tanah yang baik maka dilakukan pengujian CBR. Sampel tanah yang dipakai diambil dari daerah Tirtayasa, Sukabumi, Bandar Lampung. Terdiri dari sampel CBR proctor standar dan modified tanpa rendaman, dan CBR tekanan sebesar 5 MPa, 10 MPa, 15 MPa menggunakan tiga sampel tanah pada masing-masing tekanan. Dari hasil penelitian di laboratorium menunjukkan bahwa hasil CBR proctor tanpa rendaman standar dan modified yaitu sebesar 3,3% dan 5,8%. Sementara nilai CBR tekanan tanpa rendaman standar 5 MPa, 10 MPa, 15 Mpa yaitu sebesar 2,6%, 3,8%, 5,8%, serta CBR tekanan tanpa rendaman modified yaitu sebesar 5%, 6%, 8,3%. Dari hasil tersebut nilai CBR proctor baik standar maupun modified berada di antara tekanan 5 MPa dan 10 Mpa.
