The growing number of motor vehicles on the street will increase the consumption of gasoline. At the national scale, gasoline consumption increased from 62.035.065 kiloliters in 2013 to 70.744.977 kiloliters in 2014. The increasing consumption of gasoline not only drains the  non-renewable fossil energy but also affects the environment due to gas emission generated by fuel burning. The carbon monoxide (CO) or carbon dioxide (CO2), hydrocarbon (HC), nitrogen oxide (Nox), particulate matter (PM), and sulfide (SO2) concentration in a congestion area such as the area around traffic lights is substantially high. This research aims to find the gasoline consumption and emission rate in intersections with traffic lights, and its effect on surrounding environment. The research was done by collecting traffic volume in two locations in Surabaya, at morning rush hours, which started from 6.20 A.M. to 8.20 A.M, then calculated the emission rate and gasoline consumption from traffic data. The data showed that the volume of gasoline consumed in one lane (out of four lanes) at the traffic lights for two-hour duration was 700 liters, and the total substance of PM, NO, SO2 produced were 353 grams, 15.166 grams, and 410 grams. The concentration of NO and SO2 at Dr. Soetomo intersection after one-hour emission was 3059 μg/m3 and 57 μg/m3, while that at Kertajaya intersection was 672 μg/m3 and 12 μg/m3, respectively. These pollutants were away above the tolerable limit to human health as suggested by WHO, which should not exceed 50 μg/m3 for PM, 40 μg/m3 for NO3 for NO, and 20 μg/m3 for SO2.

Aerosol samples were collected in Phoenix, Arizona on eleven dates between July 1989 and April 1990. Elemental compositions were determined for approximately 1000 particles per sample using an electron microprobe with an energy-dispersive x-ray spectrometer. Fine-fraction samples (particle cut size of 1 to 2 μm) were analyzed for each date; coarse-fraction samples were also analyzed for four of the dates.The data were reduced using multivariate statistical methods. Cluster analysis was first used to define 35 particle types. 81% of all fine-fraction particles and 84% of the coarse-fraction particles were assigned to these types, which include mineral, metal-rich, sulfur-rich, and salt categories. "Zero-count" particles, consisting entirely of elements lighter than Na, constitute an additional category and dominate the fine fraction, reflecting the importance of anthropogenic air pollutants such as those emitted by motor vehicles. Si- and Ca-rich mineral particles dominate the coarse fraction and are also numerous in the fine fraction.

The purpose of the study are to (1) review the main problems faced by the factory of Kepuruk Manunggal Karsa (MK), and (2) assessing the entrepreneur attempts to be able to solve the problems faced. The research was carried out using qualitative descriptive design. The results showed that (1) the lack of supply of raw materials as a result of lack of capital. Sequel is due, the difficulty of the plant to meet consumer demand (excess demand). (2), the system of capital used is circulating capital (capital turnover). Earned income used up to finance the operation of the plant. (3) Innovation has been done in the form of deal with bad weather (rain) as an effort of crackers drying process is by using the oven. (4) There has been no cooperation with financial institutions. (5) There is no organizational structure as a modern factory for traditionally managed by family management. (6) Marketing using modes of transportation carts and motor vehicles.
