Analisis Karakteristik Dan Kebutuhan Parkir Di Pasar Tugu Bandar Lampung
Get PDFThe impact of the construction activity centers such as supermarkets, shops,traditional markets and others raises the need for adequate parking spacefacilities to avoid traffic congestion. Parking is an immovable state of a vehiclethat is temporary. One form of parking needs is in Pasar Tugu Bandar Lampung. However, because the existing parking area cannot accommodate the vehicle, a number of vehicles are parked along the road and causes congestion around the market. The purpose of this study was to find out and analyze the parking characteristicsin Pasar Tugu Bandar Lampung and to analyze the capacity and parking spaces needs in Pasar Tugu Bandar Lampung. The results of this study are the maximum accumulation of car is 15 vehicles while motorcycle are 116 vehicles. For the average duration of car is 19.6 minutes while motorcycle are 18.5 minutes. The results for the turnover of car parking are 1.1 vehicles/SRP/hour while motorcycle are 1.2 vehicles/SRP/hour. The maximum capacity of car parking is 31 vehicles/hour while motorcycle are 495 vehicles/hour. The parking space needs for Pasar Tugu Bandar Lampung is as much as 12 SRP for cars and 48 SRP for motorcycles. Keywords: parking, accumulated parking, parking duration, parking turnover, parking capacity, parking needs.
Review Design Pekerjaan Struktur Proyek Instalasi Rawat Jalan RSUD. Dr. H. Abdul Moeloek
Get PDFReview design proyek adalah kegiatan merekayasa perencanaan bangunan sehingga didapatkan perbandingan biaya material masing-masing. Tahapan dalam Review Design meliputi tahap pengumpulan data, penentuan metodologi, tahap analisis & pemodelan, desain & rekomendasi. Tujuan dari penelitian ini adalah untuk meninjau biaya bagian struktural dari bangunan rawat jalan seperti yang direncanakan dan membandingkannya dengan pilihan lain dari bahan konstruksi. Dalam studi ini, peninjauan hanya fokus pada pekerjaan struktural karena merupakan biaya terbesar dari keseluruhan biaya proyek. Material rencana untuk gedung adalah beton bertulang. Material alternative yang digunakan adalah baja untuk kolom dan balok serta komposit untuk pelat lantai. Dari penelitian ditemukan bahwa material yang ada yaitu beton bertulang memiliki biaya lebih rendah Rp12.029.919.096,05 dibandingkan bahan baja dan komposit yang menghasilkan biaya Rp20.732.428.550,38
Appropriateness Sensitivity Analysis of High Speed Rail Project
No full textHigh Speed Rail (HSR) is currently regarded as one of the most significant tecnological breakthrought in passenger transportation. Compare to a convensional train, a high speed train will shorten time travel. This study aims to evaluate the viability of high speed rail project based on financial analysis. The parameter used to analyse the financial viability are NPV, BCR, IRR, PP and Break Even Traffic Volume. The analyses also includes sensitivity analysis with a variety of discount rate, annual income and investment cost value. The result of financial viability analysis shows that the project does not meet the financial requirements. It is indicated by negative NPV value, IRR value of 0,27 to 2,28 smaller than the discount rate and PP value much longer than the concession period which are of 50 years. The result of Break Even Traffic Volume shows that the range of total demand number to reach NPV=0 are between 11,27 millions to 11,58 millions. The Number is very much greater than total passenger number of Argo Parahiyangan train in the year 2018 that is 4,38 millions/ year. Even though based on the financial viability analysis the High speed rail Jakarta-Bandung project is not be feasible. However, based on the economic and social benefits the project is crucial to solve traffic congestion, reduce the pollution rate, and save the time travel.Keywords :High-Speed Train, financial analysis, financial feasibility parameter
Potensi Fungsi RAP (Reclaimed Asphalt Pavement) sebagai Bahan Lapis Pondasi (Base)
Get PDFMaterial requirements for road pavement have increased along with major developments in Lampung Province. This causes the availability of aggregates to become thinner. One alternative replacement material is RAP (Reclaimed Asphalt Pavement). The aggregate in RAP becomes a potential that can be used as a basic material for road foundation layer. Therefore, research on the potential of RAP (Reclaimed Asphalt Pavement) if used as a base course material.This study uses RAP material obtained from the asphalt pavement layers on Soekarno-Hatta Street, Bandar Lampung. The results of the maximum dry density value obtained from three behaviors amount of blow is 1.965 grams / cm3, so that the resulting CBR value is 51%. This is caused during mixing and blows, the added water cannot enter perfectly into the RAP cavity. Because RAP granules are coated with asphalt so it is impermeable. So it can be concluded that the potential RAP used in this study cannot be used in road foundation layer class A but can be used as a road fondation layer class S. And if an additional of blows are made in each layer, RAP potentially can be used as a class B road foundation material.

Analisis dan Desain Elemen Struktur Beton Bertulang pada Gedung yang Memiliki Kolom Miring dengan Sistem Rangka Pemikul Momen Biasa (SRPMB)
Get PDFThe increasing development of high-rise building construction with unique design in Indonesia today can not be denied. The high-rise buildings must have earthquake resistance because of Indonesia is a country that has the risk of an earthquake. This requires a multi-storey structure designer to be able to design a multi-storey building structure with various conditions and configurations. Based on that problems, a building will be designed with unusual shape by inclining the entire main structural column with a slope angle is 80o. And as a comparison, another building will be designed which uses vertical column. The building plan will be located in Banjarmasin, South Kalimantan, Indonesia.The building plans with inclined and vertical column use reinforced concrete material with Ordinary Moment Resisting Frame (OMRF) as a structural strength system. This system is determined by the location of the building based on Indonesian Earthquake Map 2012. The result of the analysis and design is the building with inclined column has greater internal force compared to a building with vertical column and requires a reinforcement of 70.89% more than the building with vertical column.Keywords: earthquake, inclined column, building, concrete reinforcement, vertical column

Studi Eksperimental Perkuatan Balok Beton Bertulang dengan Wiremesh dan GFRP
Get PDFBalok beton bertulang adalah elemen struktur yang dapat mengalami kerusakan dan kegagalan akibat momen lentur. Kerusakan pada elemen ini dapat diperbaiki dengan perkuatan yang salah satunya adalah menggunakan Fiber Reinforced Polymer (FRP).Penelitian ini membahas perkuatan elemen balok dengan menggunakan perkuatan hybrid yaitu gabungan antara FRP dan wiremesh yang diikat dengan lem epoxy resin. Balok mempunyai bentang diantara dua tumpuan sederhana 1,5 m, lebar dan tinggi 15 cm. Balok diuji dengan dua beban titik secara bertahap dari nol sampai dengan runtuh. Balok yang diuji ada 6 buah, 2 buah balok tanpa perkuatan, 4 buah balok dengan perkuatan 2 lapis GFRP dan 2 lapis wiremesh.Hasil eksperimen menunjukkan bahwa balok dengan perkuatan mampu meningkatkan kapasitas beban sampai dengan 200% dibandingkan balok tanpa perkuatan. Beban retak awal (Pcr) balok dengan perkuatan juga meningkat 100% dibandingkan dengan balok tanpa perkuatan. Namun, balok tanpa perkuatan lebih daktail dibandingkan dengan balok dengan perkuatan
