Abstract

The use of electrical energy for each region is increasing every year, along with the community’s increasing needs. Surabaya, a metropolis in Indonesia, is listed as the third-largest user of electrical energy in Indonesia. The community has widely used solar panels as new renewable energy, such as in the construction of traffic lights, street lighting, and several households. This study aims to determine the daily performance profile of the daily value of voltage, current, and energy stored from solar panels with different types of solar panels, namely, using polycrystalline and monocrystalline solar panels mounted on the roof of the house. Data retrieval was carried out with an interval of data collection every hour when the sun is high enough until the afternoon (06:00 WIB – 18:00 WIB). The results showed that the average voltage value for monocrystalline solar panels was 21.09 V and polycrystalline solar panels were 19.32 V. In addition, the output current values for monocrystalline and polycrystalline solar panels were 0.903 A and 0.27 A. Meanwhile, the monocrystalline output power value was 19.72 W and polycrystalline 5.43 W. Based on the research data, it can be concluded that the energy stored in the battery and the efficiency value for each monocrystalline solar panel produces a higher output value than that produced by polycrystalline solar panels, 12,98%, and 4.04%. However, polycrystalline solar panels that produce a lower and stable electric current can extend the lifetime of the battery where the electric charge is stored from the solar panel.

Abstract

The East Surabaya area is one of the industrial and office centers. The high activity of the people in the city of Surabaya will affect transportation mobility which is marked by the growth of road traffic volume which continues to increase rapidly. This area has a lot of community mobility to and from the East Surabaya area. This caused congestion on several roads. Congestion is the main problem of transportation in urban areas. At certain hours there is often a spike in traffic volume that exceeds the capacity of existing roads. This is related to the starting hours of activities in East Surabaya and the ending hours of activities from East Surabaya which coincide, causing traffic jams. The East Surabaya area is divided into two times when the traffic volume increases, namely morning and evening. Based on this, this study aims to determine when there is a spike in traffic volume. The method used is a traffic volume survey, looking for peak hour volume based on cur/hour units and determining when peak hours occur. The results showed that the highest volume in direction 1 during peak hour occurred on Friday in Jalan Panjang Jiwo with a volume of 5947 cur/hour and direction 2 occurred on Friday on Jalan Jemursari. The average time for an increase in traffic volume in the East Surabaya area in the morning is 07.00 to 08.35 and in the afternoon is 15.35-18.00.
