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

ABSTRACTFor the regional goverment, the presence of the Solo – Kertosono toll road will be an alternative route free of obstacles abd reduce the travel time for vehicle users going to Solo from the direction of Kertosono and vice versa. So from that comfort and safety for users need to be considered in order to minimize the occurrence of traffic accidents.In this Final Project the methods used are he calculation of the soil carrying capacity of the Terzaqi method, manual security number with the Bishop method, security figures with the use of PLAXIS v8.2 and GEOSTUDIO 2018 applications. Where Mohr – Coulomb collapse adn plastic properties as a soil model. The purpose of this study is to evaluate and compare the calculation of soil analysis with exixting secondary data.Obtained soil carrying capacity of 578,374 kN/m2 and allowable carrying capacity of 444,903 kN/m2, safety factor (SF) of the three analyze resulted in a figure above 1,5 or a result above the safety rate in the long term. Keywords: Bishop, Geostudio, Plaxis, Soil Carrying Capacity. ABSTRAKBagi pemerintah daerah kehadiran jalan tol Solo – Kertosono akan menjadi jalur alternatif bebas hambatan dan mengurangi waktu tempuh bagi pengguna kendaraan yang akan menuju Solo dari arah Kertosono maupun sebaliknya. Maka dari itu kenyamanan dan keamanan bagi pengguna perlu diperhatikan demi meminimalisisr terjadinya kecelakaan lalu lintas.Metode yang digunakan adalah perhitungan daya dukung tanah metode Terzaqi, angka keamanan manual dengan metode Bishop, angka keamanan dengan penggunaan aplikasi PLAXIS v8.2 serta GEOSTUDIO 2018. Pada keruntuhan Mohr-Coulomb serta sifat plastis sebagai model tanah. Tujuan dari penelitian ini adalah untuk mengevaluasi dan membandingkan dari perhitungan analisis tanah dengan data sekunder yang sudah ada.Didapatkan hasil daya dukung tanah 578,374 kN/m2 dan daya dukung tanah yang diijinkan 444,903 kN/m2, angka keamanan (SF) dari ketiga analisis tersebut menghasilkan angka diatas 1,5 atau hasil diatas angka keamanan dalam jangka panjang.Kata Kunci: Bishop, Daya Dukung Tanah, Geostudio, Plaxis.

Abstract

Desa Gondang merupakan salah satu desa wisata di Kabupaten Kendal. Desa ini terletak  Cekungan Air Tanah Kendal Uangaran yang berfungsi sebagai Kawasan Resapan Air. Desa Gondang memiliki potensi pemandangan alam, hasil bumi, sumber daya air (146 mata air), dan tradisi lokal unik. Potensi tersebut dalam pemanfaatannya harus diberikan arahan pengaturan agar tetap lestari. Materplan desa wisata hijau merupakan sebuah upaya menarahkan investasi jangka Panjang agar lingkungan tetap lestari. Tujuan penelitian ini ini adalah untuk menjabarkan proses penyusunan mastaerplan desa wisata hijau di Desa Gondang, berdasarkan kearifan local. Penelitian ini menggunakan metode pendekatan Deskriptif kualitastif, dengan tahapan pengumpulan data dan informasi, analisis dan penyusunan konsep desain. Proses pengumpulan data dilakukan dengan wawancara mendalam, diskusi terfokus, serta pengamatan langsung. Analisis data dilakukan dengan memverikasikan parameter desa wisata hijaudengan fakta empiris, dan kemudian diabstraksikan untuk menyusun konsep masterplan desa wisat hijau. Produk akhir penelitian ini berupa arahan pengaturan program pengembangan.

Abstract

Gondang Village is a tourist village in the upper part of Kendal district with high morphological characteristics (tends to be hilly). Gondang village is currently developing as a tourist village, only tourism that is developing leads to mass tourism which is oriented towards bringing in large numbers of tourists. This condition is certainly very contrary to efforts to develop tourist villages which place more emphasis on conservation aspects. The consequence is an increase in disaster risk, both in the form of increased run off during the rainy season (increased flood discharge) and drought during the dry season in shaded areas, as well as increased ground movement. This community service aims to find solutions so that tourism village development efforts can still run, but can reduce disaster risk by disaster mitigation. The disaster mitigation in question is by regulating land use based on multiple disasters and improving the structural design of tourism supporting facilities and infrastructure.
