Abstract

The stress-strain response of the basic concrete making material, i.e. the mortar and aggregates, are well known. In general, the aggregate behaves linearly up till failure, possessing a very high ultimate compression strength and stiffness. The behavior of mortar is non-linear, even at low loading levels. The resulting composite material, the concrete, exhibits a less stiff response, in combination with degradation in strength. This study looked into the influence of the centroid distance and configuration of a 100x100x50 mm mortar specimen. Two inclusion configurations were considered, parallel and diagonal to the line of loading with the distance variety. It was shown that the centroid distance and configuration strongly influenced the strength, the stiffness, and failure mode. The strength behavior had a minimum and a maximum bifurcation point, while the stiffness response increased, as a function of an increase in the inclusion-to-specimen volume ratio. Visual observation of the cracking pattern revealed that the initial cracking was always situated at the interface between the aggregate and mortar in tension and propagated through the mortar matrix. It was also perceived that the crack propagation path of the very dense, diagonally arranged inclusions deviated from the columnar configuration observed from the parallel inclusion formation.

Abstract

Faculty of Public Health is one of faculty in Diponegoro University which is inseparable from parking problems. Due to increasing the number of students and vehicles ownership, the parking space requirements are exceed its capacity. To determinate the parking space unit (SRP) using Pedoman Teknis Penyelenggaraan Fasilitas Parkir,1996. Current parking capacities based on SRP are 242 vehicles for students motorcycles, 37 vehicles for cars, and 32 vehicles for employees and lecturers motorcycles. Parking space requirements based on the survey results and analysis are 360 vehicles for students motorcycles, 18 vehicles for cars and 36 vehicles for employees and lecturers motorcycles. To reach the parking demands, it shall need several steps of optimization. The first  step is  rearranging parking configuration based on parking space requirements according to survey results. After parking configuration setup, parking space requirements have not been fullfilled. The second step is class rescheduling. It's needed in  order to get optimal parking demands. After class rescheduled, parking space requirements for students motorcycles became 310 vehicles. To solve the problem of parking space requirements which exceed its capacity, it is necessary to restructure or change the configuration of the parking supplies in an optimal order capacity of parking spaces to serve the parking demands. Optimize the configuration of parking spaces by changing the functionality of some of  cars parking to motorcycles parking thus the parking space being adequate.

Abstract

SNI 03-1726-2002 mentions that the seismic requirements for building construction design should be based on 4 accelerograms from 4 different earthquake events. One of them is El Centro (California, 1940). In 2010, Indonesian Earthquake revision team defined a new seismic hazard maps. Those efforts have led to revisalSNI 03-1726-2002, because after 2002, there was earthquakes, whose magnitude was bigger than the estimation before. This study will analyze the spectrum response that will be showed through maps of amplification factor distribution and acceleration spectrum on Semarang city area. From those maps, amplification factor value of El Centro earthquake will be compared to the others (Hector Mine, Kobe, and Loma Prieta). Also the comparison of acceleration spectrum value ( PGA, T=0.2, T=1) that caused by Earthquake El Centro and the others. The last is the comparison of  spectrum response that was the result of this study and the spectrum response from SNI 03-1726-2002.

Abstract

Pengekangan pada beton bertulang yang diakibatkan adanya confinement berpengaruh terhadap peningkatan kekuatan tekan beton pada daerah terkekang dalam menerima kuat tekan. Perbandingan jarak antar confinement dan sengkang merupakan salah satu variabel yang berpengaruh terhadap peningkatan kekuatan beton. Penelitian ini menyajikan studi mengenai pengaruh dari penggunaan confinement pada jarak yang berbeda dan mengevaluasi hasil dari 12 konfigurasi jarak sengkang dan confinement dengan menggunakan program Abaqus. Benda uji yang yang digunakan menggunakan 3 jarak sengkang masing-masing berjarak 70, 125 dan 200, sedangkan confinement berjarak, 70, 125, 200 untuk masing-masing jarak sengkang. Hasil analisis menunjukan bahwa pemasangan jarak sengkang semakin besar untuk jarak confinement yang sama, akan menurunkan daktilitas balok dan jarak confinement 70 mm dalam penelitian merupakan nilai optimal sebagai jarak antar confinement. Hasil analisis untuk model S7C70 memperoleh nilai daktilitas sebesar 4.65, untuk model S125C70 memperoleh nilai daktilitas sebesar 4.59, dan untuk model S200C70 memperoleh nilai daktilitas sebesar 4.58.

Abstract

SCGC Concrete (Self Compacting Geopolymer Concrete) has the advantage of being easier and more effective in casting, so it can be applied to strengthening building structures, including the Concrete Jacketing method and voute / haunch beam. This reinforcement method is a form of composite concrete application with different concrete ages, which consists of existing structures with conventional concrete material and jacket or haunch section with SCGC concrete material. This study aims to determine the characteristics in the form of direct tensile strength, flexural tensile strength, and pull off tests (bond test) to test the strength of adhesion between concrete joints. Making specimens consists of 4 x 4 x 16 (cm) flexural tensile test beams, and 15 x 15 x 60 (cm) pull off specimens, and direct tensile specimens in the form of numbers 8. The principle of making test specimens is done by casting twice The first casting is done on the first half of the mold, then wait until the concrete age is 28 days. Then a second casting is carried out in the next half, until the concrete age is 28 days. So that the total age of concrete in making connection test specimens is 56 days. From the results of this study it was found SCGC concrete has a higher adhesion than conventional concrete so that SCGC concrete can be applied for structural reinforcement.

Abstract

DTA Waduk Pendidikan Diponegoro merupakan wilayah yang berkembang pesat akibat berdirinya Universitas Diponegoro. Hali ini membawa dampak buruk akibat berkurangnya daerah resapan air di wilayah tersebut. Beberapa titik lokasi di DTA sering mengalami genangan air atau banjir saat musim hujan. Hal ini sangat mengganggu aktivitas warga. RW 2 Kelurahan Tembalang merupakan salah satu lokasi di DTA Waduk Diponegoro yang sering mengalami banjir. Berdasarkan hasil survey terdapat tiga titik rawan banjir/genangan di kawasan ini yaitu di Masjid Miftahurrohmah, Gg Maerasari 2 dan Masjid LPPU. Banjir/genangan tersebut disebabkan oleh lokasi titik yang lebih rendah dari kawasan sekitar sehingga menerima limpasan air hujan yang cukup besar saat hujan sedangkan saluran drainase eksisting tidak mampu menampung limpasan air hujan tersebut. Oleh karena itu, perlu dilakukan penataan kembali dan peningkatan fungsi jaringan drainase di DTA Waduk Diponegoro. Penataan drainase dilakukan dengan merencanakan jaringan saluran drainase baru serta melakukan perhitungan dimensi saluran sesuai dengan perhitungan debit limpasan air hujan. Hasil survey dan perencanaan penataan drainase ini kemudian disosialisasikan kepada warga RW 2 Kelurahan Tembalang. Hasil sosialisasi yang dilakukan dapat memberikan informasi terkait kondisi drainase RW 2 Kelurahan Tembalang dan memberikan solusi serta pengarahan kepada masyarakat dalam penataan drainase lingkungan mereka.

Abstract

Construction sector in Indonesia, especially for road construction projects are progressing very rapidly in recent years. Indonesia is intensively implementing the road construction project, from new road construction, road maintenance and repairs. Road construction sector in Indonesia is mostly using the conventional contract system, with a lump sum or unit price. In this conventional contract service user must fully bear the risks associated with the quality of work that is to be maintained. It required an innovative method in order to contract the service user and the service provider can be better off, for example with the system performance based contracting (PBC). This study will analyze the differences between the PBC system and conventional system by comparing the life cycle project, project coordination line, the construction, the maintenance period, and the budget plan contract. The research method used was a descriptive analytical methods and data collection through direct field observations and interviews with project case studies Construction Project Semarang-Bawen Road with PBC and Construction Project Semarang-Solo Highway. From the results, the fact that the PBC has a single stage system that is not present in the conventional contract there is system maintenance services. At  the PBC system imposed fines ranging from construction period while the conventional system of fines awarded the contract if the contract or is unable to complete the construction work by the duration of time that has been given. At the PBC system there is not planning consultant contracts while the conventional system, there are consultants planning consultant. At the PBC system maintenance is faster than the conventional contract system maintenance. The budget plan contract at the PBC system is higher than the conventional contract system’s budget plan contract.

Abstract

Construction also causes environmental pollution due to excessive cement production, so an alternative to cement is needed. Geopolymer is considered an alternative material to replace cement. This research compares three variations of mortar (PPC, geopolymer, and geopolymer with white soil) in a seawater environment. Research in the laboratory with 5x5x5 cm mortar specimens and test parameters for porosity, compressive and direct tensile strength, density, and absorption has been carried out. Microstructure due to immersion effect was also carried out but only on MGT15 mortar. The results showed that the PPC mortar had the highest compressive and tensile strength among the three variations, namely 27.80 MPa and 2.540 MPa at 28 days of age, the most negligible porosity and absorption were 1.124% and 76 gram/100cm2, and increased density after immersion. However, when immersing for 56 days, the decrease in strength reached 21%, while geopolymer mortar tended to be stable and even increased to 19%. Microstructure tests in the form of SEM and EDX on MGT15 showed the effect of seawater immersion, such as the presence of cracks, ettringite, and bad reactions. Soaking in seawater caused a decrease in some mortar strength supporting compounds and the appearance of 0.3% free chloride at 28 days of immersion.
