Queuing in the bus station often causes traffic jam which will influence the run of the system owing to the fact of the special of the BRT system. It was after analyzed the fact of the BRT system, created the model about the probability of the vehicle reaching the station without queuing and other service index by use of the queuing theory in order to calculate the number of BRT parking space. The calculating result which is based on the Shangshe bus station of Guangzhou BRT system show that the model is reasonable and effective.

The object of the study is the improvement of traffic management on the main street and road network of the city. Actually, there are many techniques that allow simulating the traffic flows with sufficient accuracy. One of such models is a mathematical model, which allows calculating the main characteristics of a traffic flow on the basis of a few initial data and is considered as a queuing system.Modeling allows pre-determining the impact of traffic management measures on the existing street and road network without creating interference for drivers, making changes to the design of road, increasing the traffic volume, as well as involving the possible overloaded areas.An analysis of the researches of scientists who have considered similar methods in their works had been performed. The fundamental flaw of the mentioned works is that in none of them the study of the model of a real road section was performed for verifying of the model adequacy. Modeling allows understanding more accurately the behavior of an object with less approximations than mathematical models, and provides less researching and forecasting of the system behavior with significant changes in the initial concepts. It is indicated that for the first approximation it is expedient to use mathematical models, and for clarifying the characteristics – to use non- mathematical methods, in particular, simulation.It is proved that simulation is a powerful tool for studying the behavior of real systems. It is mainly used to study situations and systems that can be described as queuing systems.Using the queuing theory, it becomes possible to perform certain calculations and determine indicators of effectiveness of the queuing system.Obtained result of the indicators will help to determine the street and road network areas where a traffic jam may form for any reason, where the road will be overloaded. This makes it possible to develop a high-quality algorithm for quick elimination of traffic jam.

Terminal Dara is the center of community activities in meeting the needs for movement from one place to another with various purposes used by the people of the of Bima City and Regency. Terminal Dara has experienced a decline and an increase in the number of transportation from year to year; this condition makes facilities and operational performance at the Dara Terminal become very important. The purpose of this study is to determine the operational performance and facilities as well as the current area of Dara Terminal facilities. The method used in this study is a direct survey in the field for primary data by recording the bus license plate, time of entry and exit of buses and visitors vehicles at the entrance and exit gate and recording the number of passengers and users of waiting rooms, the number of seats in passenger waiting rooms, and bus station facilities. Data collection is carried out for three days with duration of 13 hours each day.Based on the results of the analysis of the performance that has been carried out, the value for the bus queue analysis ρ = 2.11> 1 indicates that there is a queue of bus services at Dara bus station. The highest value of arrival average time headway is 17 minutes 22 seconds and the departures average time headway is 12 minutes 23 seconds. The highest departure load factor is 81.44% in the ANGDES and the highest load factor is 73.64% in ANGDES too. The parking space requirement for cars and motorbikes of 128 m² can still be served by vehicle parking area in bus station, while the parking area for bus is not able to serve bus which parked in the bus parking area with the value of parking space needs 902.5 m² while the area the current bus parking area is 631.25 m². Based on the results of the performance analysis that has been done, the value obtained for bus queue analysis ρ = 2.11> 1 indicates that there is a queue of bus services in Dara Terminal. The time between the highest average arrivals is 17 minutes 22 seconds and the time between the highest average departures is 12 minutes 23 seconds. The highest departure load factor was 81.44% at ANGDES and the highest arrival load factor was 73.64% at ANGDES as well. The need for parking spaces for private cars and motorbikes of 128 m² can still be served by the terminal private vehicle parking area, while the parking area for buses is not able to serve buses that park in the bus parking area with a value of 902.5 m² of parking space while the area the bus parking area is currently 631.25 m². Based on existing survey results, the bus departure lane and passenger lounge of Terminal Daral need to be renovated, or they can relocate the terminal to a wider area.

Sumedang tofu is one of favorite foods for Indonesian society. But many sellers or producers are not aware to the food safety of sumedang tofu. The aims of this study were to analyze the microbial, formalin, and lead (Pb) contents in ready-to-eat sumedang tofu which were sold in traffic jams area in Cicurug, Ciawi, and Cisarua. The analysis were carried out by Total Plate Count (TPC) testing for microbial analysis, potassium permanganate reaction (KMnO4) testing for formaldehyde analysis, and atomic absorption spectrophotometry (AAS) method for lead content analysis in the samples. The results obtained for the microbial analysis were sumedang tofu that were sold in the traffic jam areas of Cicurug, Ciawi, and Cisarua contained contaminant above the treshold (1.4 x 105 colonies / gram to 2.2 x 105 colonies / gram of microbes). All of the samples of sumedang tofu were positive containing formaldehyde. Otherwise, there were no lead (Pb) content in all samples regarding to AAS analysis. This study concluded that the ready-to-eat sumedang tofu those were sold in traffic jam area in the Cicurug, Ciawi, and Cisarua were not suitable for consumption because it contained exceed microbial contamination and formalin which are harmful for human health.Keywords : formalin, microbes, sumedang tofu, lead, traffic jam
