Traffic lights have a vital role as regulatory systems to control the vehicles flowed in urban networks. This research is based on the real case. The traffic lights are installed at a massive intersection of an urban network consisting of four sections. The systems control implements the modification of the Norwegian traffic lights states. The behavior of traffic lights states were modeled using Petri net method. For the model verification and validation, the invariants and simulation were applied. The purpose of the implementation of this control system was to reduce travel delays. The intersection performance level was good while the average travel delay on all sections was low. The method used for the testing was the comparison of the simulation results due to the settings that apply the standard system to the imitation of the reality of the system using modifications of the Norwegian traffic lights states. The control system was able to reduce the travel delays slightly. The average of Level of Service (LoS) index of the roads for all sections was at level D. It improved the performance of the intersection, but not yet significant. In addition to setting traffic lights, the presence of flyovers is urgent to improve travel delays.

The government promotes rural infrastructure development through Village Fund Allocation (ADD). In the process of planning, development and reporting the village government is given the broadest authority. This authority requires the village government to have the ability to prepare a Budget Plan (RAB) and report on the use of funds. The ability of village communities in preparing Budget Plan for the Talud is still minimal and training is needed to improve their abilities. The results of this training are expected to be beneficial for the people of Tladan Village, Kawedanan District, Magetan regency so that the infrastructure development program in the village will run better and achieved good quality.

Mathematical modeling assumes that the vehicle’s volume has a uniform pattern. Due to traffic lightssettings, the number of vehicles queue grows linearly. The reality, the stochastic arrivals of the vehiclescould be (1) in the randomized arrivals, (2) in the form of groups/ platoon, or (3) in the mixed arrivals. Itis observed that the arrival of the vehicles in the queue tends to have a normal pattern. The objective ofthis research is to study the implications of the arrival categories to the travel delay. For simulation, ituses the numerical method referring to the real state. The result indicates that the calculations of thetravel delay become precise for all vehicles.

The purpose of this research is to build the proper travel schedule of traffic flow at a signalized intersection that has a special barrier. There exists a train track on one arm. The closure of the railway gate is longer than the duration of a cycle of traffic lights which causes congestion. This research uses graphs representation 146 Tomi Tristono method. It is based on the reason that a directed of the planar graph can devote conflict-free of the traffic flow in the urban network. The result is a graph model traffic flow and a proper time travel schedule. The benefits can be used by relevant agencies as basic of vehicle traffic regulation especially while the railway gate closing and after the train crossing completely.

This paper presented the seismic evaluation of the existing building structure in Madiun city. The selected building analysis is Parkir Building of Pasar Besar Madiun city that located at Panglima Sudirman street Madiun city Indonesia. The structural system of this building is Moment Resisting Frame (MRF). The building structure is reinforced concrete. Seismic load calculation use equivalent static load analysis base on Seismic Resistance Design Standart for Building Structures (SNI 1726:2012). Pushover analysis of this building use software ETABS version 9.00. Aim of this research to know the performance level of this bulding. The pushover analysis is a relatively simple tool for Performance Based Seismic Evaluation (PBSE).

The rapid economy growth in Indonesia encourages the developments in all fields. One of them is the development of infrastructure on housings, transportations, and irrigation. Constructions of concrete building are used on the road, bridges, buildings, housing, and water buildings. A concrete is a material structure of building that made from mix of sand, gravel, cement and water as adhesive. All the materials of the concrete were derived from the nature. To avoid the excessive exploration of nature resource the method of recycling of used concrete to become new one were needed. The used concrete was used for coarse aggregate. To improve the quality of concrete from the used one, additional material was required, that is, fly ash. The test material were formed of cube of 15x15x15 cm in size. From the result of research, the analysis can be done in order to find the relationship between quantity of fly ash to be added and the quality of concrete can be formulated as y =-34.921x2 + 11.45x + 25.465, in which y is compressive strength and x is the percentage of fly ash. Thus, for maximum addition of fly ash of 16.4 %, it obtains the maximum compressive strength of concrete of 26.4 MPa and the age of concrete is 28 days. The method of recycling of used concrete and the use of fly ash to become the material of new concrete are safe environmentally, which can overcome the nature filthy especially from the waste of used concrete and coal. Therefore, this is in line with the principal of nature preservation, those are Reduce, Reuse dan Recycle.
