Abstract

Sugio Village Market is a traditional market located in Sugio Hamlet, this market is the only market in Sugio sub-district therefore this market is always crowded with people who want to shop for basic necessities every day. Market activity that causes an increase in the volume of vehicles entering and leaving the sugio market at certain hours makes it difficult for some vehicles to find a place to park. The method used in this study is a field survey by recording vehicle license plates in and out of the parking area. From the vehicle data is then analyzed to obtain accumulation, duration, parking volume, parking turnover rate, parking index and parking space needs. The results of this research were that the highest parking accumulation for motorbikes was 29 vehicles, while the highest accumulation for cars was 9 vehicles, the highest parking volume for motorbikes was 118 vehicles and the highest parking volume for cars was 12 vehicles, the highest average parking duration for bicycles. motorbikes are 1.91 hours/vehicle while for cars it is 3.5 hours/vehicle, the maximum parking capacity which can accommodate motorbikes is 204 vehicles/hour and to accommodate cars is 3 vehicles/hour, the highest parking index for motorbikes of 1.56 and the highest parking index for cars is 3.5, the highest parking turnover rate for motorbikes is 0.549 vehicles/srp/hour and the highest parking turnover rate for cars is 0.400 vehicles/srp/hour, for parking space needs additional area is needed land of 31.5 m2 for parking on the east side and 19.85 m2 for parking for motorbikes on the south side, while for cars an additional parking area of 113.75 m2 is needed in the area on the south side.

Abstract

In this study, Unisla's solar electric vehicles uses five 100Wp solar panels assembled in series so that it has a total power of 500Wp. The design of this solar cell power monitoring system uses ESP32 as a microcontroller with the concept of Internet of Things (IoT) so that the device can be connected to the internet in real-time. The sensors used to read the current and voltage flowing from the solar panel are the ACS712 sensor and the voltage sensor is a voltage divider circuit made from resistors with R1 66100 Ohm and R2 3200 Ohm values respectively. Of the 10 test samples, the average error value of the voltage sensor used had a fairly good accuracy, with an average error of only 0.301%. This shows that the measurement difference between the sensor and the multimeter is relatively small. Meanwhile, the measurement difference between the ACS712 sensor and the power supply is very small, ranging from 0.01 to 0.02 Amperes with an average error of 0.01%. This shows that the measurement deviation of the ACS712 sensor compared to the reference value is very small, making it reliable for current measurement applications. The power monitoring tool developed was successfully implemented on Unisla Solar Electric Vehicles in real-time. Tests show that the appliance can read the voltage, current, and power generated by 5 solar panels assembled in series with a total power of 500Wp. The highest rated voltage data is 73.12Volts at 14.00, while the lowest data is 65.22Volts at 17.00, the rated highest rated current is 7.11A at 12.00, while the lowest current is 1.10A at 17.00, the highest rated power is 505.65Watt at 13.00, while the lowest power is 71.74 Watts.

Abstract

With the increasing use of concrete in the construction sector, the demand for its constituent materials, particularly cement, has also continued to rise. This study utilizes Lapindo mud as a partial substitute for cement, based on the fact that Lapindo mud contains chemical compounds similar to the main components found in cement. The objective of this research is to determine the effect of using Lapindo mud as a partial cement replacement in concrete. The study was conducted using an experimental method and referred to the Indonesian National Standard (SNI) 03-2834-2000 for concrete mix design. A total of 12 cylindrical specimens were prepared with a target compressive strength of 250 kg/cm² (K-250). The planned Lapindo mud replacement levels were 0% (normal concrete), 2%, 4%, and 6% of the cement content. Compressive strength tests were performed at 28 days of curing using a Compressed Test Machine. The average compressive strengths obtained for concrete mixes with 0%, 2%, 4%, and 6% Lapindo mud were 20.95 MPa, 19.06 MPa, 18.26 MPa, and 17.02 MPa, respectively. Based on the results, it can be concluded that an increase in the percentage of Lapindo mud in the mix leads to a decrease in the compressive strength of concrete.
