Abstract

ABSTRAKS   Pengujian balok beton eksternal ini menguji tentang pemanfaatan tulangan eksternal sebagai pengganti tulangan pada beton. Pemasangan baja tulangan eksternal direncanakan bukan dari batang baja tulangan yang berpenampang lingkaran, melainkan baja lips channel yang memiliki lekatan, dan pengekangan pada balok beton. Lips channel sebagai perkuatan di tepi luar balok beton akan menggantikan baja tulangan beton yang tertanam di dalamnya, sehingga jarak antara titik berat lips channel di serat tarik (bawah) dan titik berat daerah tekan balok beton lebih besar. Material terluar beton yang memiliki nilai regangan yang lebih kecil dapat tergantikan dengan baja. Penggunaan tulangan eksternal baja lips channel pada balok beton yang menerima beban lentur sangat menarik diteliti, khususnya cara mengurangi bahkan meniadakan slip antara baja lips channel dan beton. Mutu beton rencana adalah f’c 45 MPa (K500) dengan panjang uji benda 180 cm, lebar 12,5 cm, tinggi 18,5 cm. Kata kunci : Baja Lips Channel, beton bertulang, Slip   ABSTRAKS   Testing of concrete beams externally tested on the use of external reinforcement in concrete reinforcement instead. Installation is planned external reinforcement steel rods instead of steel reinforcement Berpenampang circle, but lips steel channel with coherence, and restraints on concrete blocks. Lips channel as reinforcement at the outer edge of the concrete block will replace the concrete reinforcing steel embedded in it, so the distance between the center of gravity in the fiber channel lips pull (bottom) and gravity concrete beams hit area larger. Concrete outer material has a smaller strain values ​​can be replaced with steel. The use of external reinforcement steel in concrete beams lips channel receiving bending loads very interesting study, particularly how to reduce and even negate the slip between the steel and the concrete channel lips. Quality concrete f'c plan is 45 MPa (K500) with a lengthy test object 180 cm, width 12.5 cm, height 18,5 cm. Keywords: Steel Lips Channel, Reinforced Concrete, Slip

Abstract

Work on the building project requires a material that is more complex and involves many parties so that the building project has a high complexity compared to other civilian buildings. One of the complexity of such problems in the procurement of materials. Some of the things that causes this problem is the existence of an uncertainty in the supply of construction materials. Reinforcement steel is the main ingredient in development , especially the construction of the building. The need of reinforcing steel required at each work ranging from foundation work , beams , plates and columns. Therefore, the availability of steel reinforcement is a major priority so that there should be no delay in procurement. Delays of this material may be caused by uncertainties in procurement activity. Uncertainties in the procurement of materials sourced from four stages: stage supply chain activities supply, control, process, and demand. The stages of the supply chain to be a reference to analyze the possibility of delays in the procurement of a material. Thus, this study aims to determine how much time minimum and maximum time delay procurement of materials, the maximum possible delay in work activities and work activities that are most likely and dominant risk that affects the delay procurement of materials for steel material. The major delays in the procurement of material obtained from the analysis of probability and risk impact with monte carlo method and application assistance crystal ball. In the procurement of steel material analysis showed that a minimum delay of 2.20 days,17.05 days maximum, the maximum possible delay in work activities 15.05 days, and delays in work activities that are most likely 9.24 days. Sources of risk that affect the delay is on the demand stage that ordering additional material due to design changes, material delivery delays due to financial problems, and ordering additional material due to changes of function space.

Abstract

Terminal Mangkang which was a type-C terminal, is now upgraded to be a type-A terminal, located in the western side of Semarang City. Terminal Mangkang, specifically the urban transit area, has several issues, for instance the lack of vehicle circulation system due to several meeting points of the arriving and departing vehicles. Besides, passengers get on and off the vehicles at improper places. Therefore, is a necessity to evaluate the efficiency of vehicle circulation system at the urban transit area terminal. Data was collected by giving questionnaires to 100 respondents with a sampling method, and recording method of vehicle circulation time. The questionnaire consists of ten questions focusing on travel origin and destination, type of public transit choice, and movement pattern of passengers on and off vehicle inside and outside the terminal. The result showed that majority of passengers (54%) came from western side of the city and 40% passengers used NBAK (Non Bus Angkutan Kota/ Non-Bus City Transport). For passenger movement pattern, the majority of passengers (47%) get off the vehicle inside the terminal, located at the entrance after the inclining road of TPR 41% passengers would wait for the vehicle at the exit way outside the terminal. According to the performance comparison of each type of terminal, recomendation type 2 model has seventy-eight-second of efficiency on circulation time compared to the existing terminal circulation. This type 2 model will decrease the tendency of passengers to switch vehicles outside the terminal. This study recommends a rearrangement of terminal layout to facilitate the activity of circulating passengers for each type of vehicle operating in the public transport terminal. The type 2 model may be considered by the stakeholders in the rearrangement of the terminal layout.

Abstract

Ahmad Yani Airport in Semarang is one of the international airport in the Province of Central Java . International airport status is used because there is a flight plan to foreign country and Ahmad Yani Airport worthy to serve the airlines. However, the facilities and services that exist not suitable for international-class airport. Therefore, these airports continue to be developed in order to serve the demand for overseas flight, both domestic and international flights increased from year to year. It can be from Semarang and head to Semarang. The development includes the development of the infrastructure of the airport land and air sides which are divided into two phases. With the completion of the first phase of development, Ahmad Yani Airport will have a wider terminal in the North of  runway, ample parking space, covering an area of 61.344 m2 apron and two taxiways. Development of second phase will make Ahmad Yani Airport has an area of 78.313 m2 apron that can accommodate 12 Boeing 737-900 aircraft class and 8 pieces taxiways, 2 pieces exit taxiways and 1 piece parallel taxiway. This Final Thesis will analyze the air side of the Ahmad Yani airport that has runway formed, taxiway and apron at the existing condition, the development of the first phase and the second phase of development. This analysis will have predicted number of passengers in the plan of year which will then be converted into the number of aircraft at busy times. Results of the predicted number of aircraft will be on an analysis for the air side capacity of the Ahmad Yani Airport in the development plan that has been done by Ahmad Yani airport, so that it will be known the air side ability of the Ahmad Yani Airport to the demand in the plan year. This analysis refers to the rules that set up by FAA. Results of the analysis showed that when the condition of existing air side in the form of runway, taxiways are still able to serve the demand of flight but the capacity of the apron are not able to serve so for prediction of the next 5 years in the first phase of development there will be over capacity. However, with the development at the Ahmad Yani Airport, aircraft servicing predictions for the next 5 to 10 years can already be served by a taxiway and apron but rapid exit taxiway should be built for runway’s component, so that it can increase runway capacity at peak hours.

Abstract

Kemacetan merupakan suatu permasalahan pada sektor transportasi yang sampai saat ini masih belum ditemukan solusinya. Bahkan, jalan tol yang merupakan suatu sarana untuk mengurangi kemacetan ternyata tidak luput dari kemacetan itu sendiri. Penelitian yang dilakukan difokuskan pada jalan tol Brebes Timur yang baru saja selesai dengan studi kasus arus mudik 2016. Pengumpulan data terkait kasus Brebes Timur, meliputi data lalu lintas pada ruas Kanci-Pejagan, serta lalu lintas pada tiap Gerbang yang diteliti, yaitu Gerbang Tol Pejagan, Brebes Barat, dan Brebes Timur. Tujuan dari penelitian ini adalah untuk mengetahui faktor penyebab kemacetan serta memberikan salah satu solusi dari kemacetan melalui simulasi sistem buka tutup pintu gerbang yang ada pada ruas tol yang diteliti. Metode yang digunakan adalah simulasi dari sistem buka – tutup dilakukan tanpa adanya survei data langsung, dikarenakan kasus yang diangkat sudah lama terjadi. Simulasi ini memanfaatkan data sekunder dari operator jalan tol yang bersangkutan. Analisis pada pembahasan meliputi kapasitas maksimal dari tiap gerbang, antrian yang terjadi, serta simulasi sistem buka tutup gerbang tol dengan alternatif penambahan gardu dan pembatasan antrian sebesar 3 km, 4 km, dan 5 km. Hasil dari analisis adalah simulasi dilakukan dengan menetapkan batas antrian pada tiap gerbang untuk menentukan kapan waktu sistem buka dan tutup itu dimulai. Kesimpulan dari studi ini yaitu faktor penyebab dari kemacetan yang ada adalah tingkat kedatangan yang sangat besar (2584 kend/jam pada Gerbang Tol Brebes Timur, 976 kend/jam pada Brebes Barat, 1742 kend/jam pada Pejagan) yang tidak sebanding dengan kapasitas pelayanan yang ada, dinyatakan dengan besaran . Jika  semakin mendekati 1 maka gerbang semakin jenuh, jika   maka gerbang tidak mampu melayani tingkat kedatangan yang ada (1,076 pada Gerbang Tol Brebes Timur, 0,813 pada Brebes Barat, 0,967 pada Pejagan). Simulasi yang paling efektif untuk dilakukan adalah simulasi dengan batas antrian sebesar 4 km dengan waktu pelayanan tiap gardu 12 detik dan tanpa adanya penambahan jumlah gardu. Sebagai tindak lanjut dari studi ini adalah perlu adanya data yang lebih lengkap agar perhitungan yang dilakukan lebih rinci dan mendalam, serta ketika simulasi dilakukan perlu adanya komunikasi yang baik antar gerbang tol terkait untuk menginformasikan arus dan panjang antrian yang terjadi untuk menentukan pembukaan dan penutupan gerbang yang dilakukan.

Abstract

Siliwangi road is one soars and populous Primary Arterial Road in the Semarang City, so often there is congestion on the roads. Result of frequent congestion on the roads, air pollution which occurs also higher. This study aims to determine how high the air pollution that occur and to provide recommendations for alternative solutions to tackle congestion at the intersection whole observatories, so as to minimize the air pollution that occurs. Traffic survey at the intersection whole observatories done during the morning Peak hour, afternoon Peak hour and evening Peak hours. Survey results are then processed by the Manual Kapasitas Jalan Indonesia (MKJI) 1997 Synchro SimTraffic Program 7.0. Initially, the green time adapted to the needs of the existing condition, then the following adjustments were made in the form of changes in the geometric intersection to accommodate existing traffic conditions. Adjustment of the traffic conditions and the geometric path then known how much pollution that occurred at the intersection. At the intersection of the existing conditions in whole observatories already reached saturation performance , with the calculation of the degree of saturation of the synchro program 7 that almost all of them are above the 1.00 figure. With the adjustment Optimization green time to Simpang whole observatories provide DS to decrease Morning Peak condition that is equal to 5.82%, 5.82% Peak Afternoon, Evening Peak 9.89% and the change in geometric intersection (lane additions of 3.7 m) on condition Morning Peak, Peak Afternoon, Evening Peak resulting decrease in DS respectively 23.80%, 8.95%, and 14.58%. Although not all perform well and there are still some poor performers approach (indicators of poor performance where the value of the degree of saturation exceeds the ideal value of the degree of saturation (DS>0.75). Use of Public Transport assuming 50% removal of the car was replaced with highly efficient use of BRT in reducing the number of DS on condition Morning Peak , Peak Lunch, Afternoon Peak resulting decrease in DS respectively 60.84%, 47.01%, and 61.97%. The scenario design is done well enough for the level of handling performance in the short term. So, it can be concluded that the performance of intersections that were reviewed for the better.

Abstract

Lokasi blackspot di Provinsi Jawa Tengah tersebar di berbagai wilayah, 56 titik berada di Jalan Pantura. Dari jumlah tersebut, sembilan titik merupakan tikungan dan empat titik diantaranya adalah tikungan tajam. Kecelakaan pada tikungan dapat disebabkan oleh kondisi geometrik, kecepatan kendaraan dan kesalahan manusia. Penelitian ini dimaksudkan untuk mengetahui karakteristik kecelakaan pada tikungan rawan kecelakaan ditinjau dari aspek geometrik, kecepatan dan persepsi pengemudi.Lokasi penelitian berada di Jalan Losari Kabupaten Brebes, Sidorejo Kabupaten Pemalang, Plelen Kabupaten Batang dan Juwana Kabupaten Pati. Data yang diperlukan adalah data kronologis kecelakaan, geometrik tikungan, serta kecepatan operasional kendaraan dan persepsi pengemudi untuk mengetahui karakteristik pengemudi saat melewati tikungan.Komponen geometrik tikungan yang dievaluasi adalah radius tikungan, panjang lengkung spiral, superelevasi, lebar lajur, lebar bahu dan lebar median. Berdasarkan pengamatan, aspek geometrik yang umumnya tidak memenuhi standar teknis, adalah radius, lebar lajur, lebar bahu, dan median. Dari aspek kecepatan, kecepatan operasional di lokasi pengamatan lebih tinggi dari kecepatan teoritisnya kecuali di Tikungan Juwana. Kecelakaan di tikungan yang tidak mempunyai median (Tikungan Plelen dan Tikungan Juwana), didominasi oleh tabrakan jenis head on. Selain itu, tingkat fatalitas kecelakaan (EAN) cukup tinggi dibandingkan dengan tikungan yang mempunyai median. Pada tikungan yang mempunyai median (Tikungan Losari dan Tikungan Sidorejo), jenis tabrakan yang dominan adalah rear end dan Angle. Ketidaktersediaan rambu dan kurangnya lampu penerangan pada tikungan menyebabkan tingginya jumlah kecelakaan. Tikungan dengan radius yang lebih besar memiliki kecepatan operasional kendaraan yang juga tinggi. Rekomendasi penyelesaian untuk permasalahan tersebut adalah penambahan rambu lalu lintas, perbaikan superelevasi, penambahan lampu penerangan jalan dan median.

Abstract

Persona Hotel located on the main route from Bekasi to Jakarta, in area Jatiwaringin 60. Hotel Persona will be built vertically with the number five floors consisting of four floors and a roof floor.Building structure designed use Special Moment Resisting Frame System based on Concrete requirements for structural building Codes (SNI 2847-2013) Analysis of seismic loading was conducted using equivalent static method based on Indonesian Earthquake Resistant Building Codes (SNI 03-1726-2012). In designing this building structure, we used the concept of capacity design. The purpose of this concept was to provide enough ductility by designing plastic hinges on beam. In order to guarantee  plastic hinges are formed on the beams, the columns should be designed to be stronger than the beams (Strong Column Weak Beam). The foundation was designed as bored pile, because the soil in that area was hard soil type. The results of the structural analysis show that the Hotel Building structure was able to withstand the designed earthquake loading.
