Abstract

ABSTRACTThe rapid infrastructure development is one of the indicators on the country economic progress. Indonesia as one of the largest archipelagic countries in the world, should be prioritized the port infrastructure to support the maritime. One of the government’s solutions is infrastructure development of Kuala Tanjung port. This research analyzed bearing capacity and settlement of single and group pile foundation on port infrastructure of Kuala Tanjung so it is known that the port is safe to use. The data used are Standard Penetration Test data with soil stratigraphy that is clay and sand. The type of foundation used is Concrete Spun Pile 1000 mm and 600 mm with a pile length of 36 meters. The data are then analyzed by manual calculation and Allpile 6.5E program based on Reese method and methods such as Vesic and Converse-Labarre. The results showed that single pile foundations of 1000 mm and 600 mm each had allowable capacity (Qall) 492.78-538.81 ton and 110.65-128.31 ton, with vertical load (Q) of 330.90 ton, settlement 0.56-1.17 cm and 3.32-3.64 cm, lateral deflection 27.50 cm and 94.90 cm. While the 1000 mm and 600 mm pile group foundations respectively have Qall 8717.31-10796.29 tons and 2059.25-2566.32 tons, with Q of 6618 tons, settlement 0.56-1.68 cm and 3.32-3.64 cm, lateral deflection of 2.49 cm and 19.49 cm. The conclusion of the research indicates that the safe pile foundation used is 1000 mm group pile foundation. Keywords: Bearing Capacity; Foundations; Pile Foundation; Port Infrastructure; Settlement

Abstract

Abstract: Flooding problem still become serious problem in subdistrict Wonokerto of Pekalongan regency. There are six rivers that have the potential caused flooding in setelment area. In this research, the researcher wanted to do hydrological simulation at six rivers in Wonokerto. The hydrological simulation is done by calculating the inflow in the river in the form of flood discharge hydrograph design with nakayasu method, and evaluate the capacity of river catchment to flood discharge. Based the results research on six rivers, it is known that the river capacity is not able to accommodate the flood discharge when enters the river. The River water are also known  unable to flow by gravity caused of rob dikes that isolated the river water to flow into the sea, therefore to prevent overflow in the river needs and to prevent overflow and to control the river water level a pumping in rivers.Keywords: Hydrological Simulation, River Flood Control, Storage Evaluation, Pumping

Abstract

Abstract: Pekerjaan rehabilitasi saluran sekunder D.I Sidorejo menggunakan model pracetak dengan desain sambungan (male-female) empat sisi. Namun, pelaksanaan dilapangan pemasangan model ini mengalami kesulitan, membutuhkan waktu lebih lama dan kurang efisien. Tujuan studi ini adalah mengetahui Efisiensi Penggunaan Lining Precast Dengan Desain Sambungan (Male-Female) Dua Sisi Pada Pekerjaan Rehabilitasi Saluran Sekunder D.I Sidorejo. Bentuk penelitian ini adalah studi kasus, yaitu pada saluran irigasi sekunder di D.I Sidorejo Kabupaten Grobogan. Alat analisis yang digunakan adalah uji efisiensi. Hasil dari penelitian ini menunjukkan bahwa pemasangan lining precast empat sisi memiliki efisiensi 80% sedangkan lining precast dua sisi memiliki efisiensi 100% baik dari sisi waktu pemasangan maupun kapasitas pemasangan. Selain itu biaya pemasangan lining precast dua sisi lebih murah dibandingkan dengan empat sisi dengan selisih biaya pemasangan sebesar Rp 60.480.000 dengan efisiensi sebesar 80%. Keywords: D.I Sidorejo; Dua sisi; Efisiensi; Lining precast;

Abstract

ABSTRACTLocal traditional mining in the Bodri River Kendal regency increasingly concerned, this is of course if left unchecked will damage the river body, river channel, causing landslides, can even disrupt the stability of water buildings such as weirs and bridges. The purpose of this research is as an effort to Determine Non-Metal and Rock Mineral Mining Zonation Based on the Inflow and Outflow of Sediment in Bodri River of Kendal Regency, to obtain the areas which are allowed to be mined and the mining volume. This research is descriptive qualitative by doing direct observation, interview and documentation. Descriptive method is a method used to examine the status of human groups, an object, a condition and a system of thought and events that will occur. The purpose of this study is to create an explorative, systematics, factual and accurate facts on the specific case. The research results are sediment inflow to  the Bodri river is 103.327,40 ton/year, whereas the outflow is 379.459.46 ton/year, which mean the river morphology has serious problem caused by the mining activity. Keywords: Zoning, Mining, Non-Metal Material and Rocks, Sediment

Abstract

ABSTRACT             Floating house is a building, which stands or floats on water by relying itself on the weight and the area sunk as the load parameter compatible to the structure. This house can float or be placed on the seashore on the water. This research was conducted by comparing the magnitude of the floating force (Fa) of the three foundation materials of the houses, namely plastic drum, Styrofoam and bamboo. The materials were calculated based on the total load of the house (G), with the safety number of 1.5.  .The research result is the total load of the floating house structure (G) is 364.585,5 Newton (down), the floating force (Fa) magnitude of plastic drum as the foundation material is 549,814 Newton (upward), Styrofoam as the foundation material is 552,720 Newton (upward), and Bamboo as the foundation material is 540,883  Newton (upward). The amounts of the foundation materials for plastic drum are 232 pieces, for Styrofoam are 56 sheets, and for bamboo are 3900 sticks.  Keywords: Floating house, floating foundation, floating force, plastic drum, Styrofoam,                 bamboo
