Abstract
Air pollution caused by exhaust emission of motor vehicles especially the two wheels contain a wide range of harmful gases that can cause disease. Therefore, emission tests are indispensable in controlling the emissions of gas that are loose into the air. However, not many people know the importance of emission testing. In addition to the emission results can not store periodic data, the available emission test devices are also very limited. Therefore, the author proposes the feasibility “Test Monitoring system for motorised vehicles with Arduino-based Internet of Things”. In data retrieval use a simple linear regression method. In this tool the x-axis is the ADC value of the sensor while the y-axis is the value of gas levels. The greater the ADC value, the greater the PPM value is generated. Emission test data storage using the Internet of Things method. The Data that has been saved can be viewed through websites and Android apps. After several tests, there were 3.05% error percentage for HC gas and 3.91% for CO gas and data could be stored in the database. Overall this tool is worthy of use to measure the exhaust emissions of motorised vehicles.

Abstract
Electrical vehicle is a vehicle that uses one or more electric motors or traction motors as its driving force. Electric vehicles first appeared in the mid-19th century, when electricity was chosen as the propulsion in vehicles. At that time, electric vehicles offered greater comfort and easier operation than gasoline-powered cars. However, since the advancement of the internal combustion engine, the existence of this technology has been less competitive. The decline in the use of vehicles with electric power at that time was due to the quite expensive price, but on the other hand EV has the advantage of a very good level of environmental friendliness, because there is no exhaust gas coming out of the engine. To get a power source, EV uses electrical energy stored in the battery, because it is necessary to charge the battery embedded in the vehicle before using it. Without realizing it, the use of motorbikes has negative things including incomplete combustion results, resulting in air pollution and on the other hand the materials to operate it are also running out and running out. The electric motor can be the answer to various problems that exist today and even in the future, because the electric motor has better efficiency than the combustion motor. The disadvantage of an electric motor is that the price is quite high when compared to a combustion motor, but on the other hand, such as the maintenance and efficiency of the energy source of an electric motor, it is far superior. In addition, with the electric motor, it can overcome the problem of natural resource fuel, which is increasingly shrinking.

Abstract
The transportation sector plays an important role in realizing a smart city. The increase in the number of vehicles is currently not supported by an increase in road capacity. Traffic jams or congestion will occur in many places. Congestion will increase the accident rate, bad effect on economic growth, and increase gas emissions. Effective traffic management is necessary to reduce congestion levels and its side effects. A traffic light is one of traffic management methods. Traffic lights control the flow of traffic at road intersections, zebra crossings, and other traffic flow points. Conventional traffic lights work on a pre-programmed time sequence. This system is effective if the vehicle density is relatively constant. The density of vehicles from various directions fluctuates with time. To increase the effectiveness of using traffic light, an adaptive system is needed. In this study, a simple adaptive traffic light mechanism was developed based on congestion on the road using computer vision. Vehicle congestion is detected using the YOLOv3 object detection which detects the type of vehicle. The detection system used by YOLOv3 with pretrained weight COCO has a true positive value for motorbikes of 60%, cars (light vehicles) 93%, and trucks/buses (heavy vehicles) 100%. The processing speed of the Jetson Nano mini-PC with the OpenCV library on the GPU is 2 times faster than the process with the CPU.

Published: March 2021

Abstract
The main purpose of utilizing lignite coal in Indonesia is to decrease fuel costs in electricity and Greenhouse Gas emissions. Still, on the other hand, it will affect the reliability and plant performance. This paper attempts to evaluate 340 MW subcritical coal-fired power plant’s performance and reliability by comparing the impact of coal utilization below boiler design toward the baseline and identifying the significant factors that lead to plant efficiency and reliability. Performance tests conducted using the standard procedures at four segments of load, i.e., 50%, 65%, 80%, and 95%, with two scenarios: (1) use 3500 kcal/kg of coal calorific value, and (2) use 4500 kcal/kg of coal as the baseline. There are no adjustments during the test and all measurements, including pressure, temperature, flow, bomb calorimeter, etc., already calibrated. The results show that during 3500 kcal/kWh, 100% of the load is unable to reach. Plant performance becomes higher up to 2930 kcal/kWh, boiler efficiency decrease to 80.4%, and fans current increase to maximum capacity. The study’s conclusion suggests that the utilization of LRC must be considering the energy amount to the boiler.

Abstract
Enhancement of heat transfer by employing nanofluids have obtained important consideration over the past two decades. Nanofluid types are appropriate as the alternative working fluid for many different fields, such as automotive, air conditioning, electronics, nuclear applications, and power generation. Flow behaviour structure and heat performance and the hydrodynamic thermal characteristics of Al2O3 Nanofluid under different concavity (dimple) configuration parameters, are numerically analysed through using ANSYS FLUENT technique.
The Nanofluid is used in a three-dimension circular pipe with modified varying dimple diameters (d = 1, 2, and 3 mm) are applied for computational calculations and compared with a smooth plain pipe under different operating conditions. The outcomes of CFD analysis are presented the generation of more turbulence flow near pipe wall area can effectively improve heat transfer in dimple pipe due to the vortex flow can cause more destruction in boundary flow layer that leads to of boundary layer thickness to become thinner hence the shear stress at pipe wall is augmented. Moreover, The Nu number of dimple diameter of 3 mm is higher than other cases. The average value is 51% higher than the normal pipe. Furthermore, the dimple pipes’ performances with a concavity diameter of 1 mm have advantages than other concavity diameters under similar corrugation conditions.

Abstract
A failure phenomenon on induced draft fan (IDF) shaft became a crucial attention in Power Plant with capacity 350 MW because the failure is catastrophic without early warning information. Also, the failures on the IDF shaft occurred in a short period within two months. This paper reported an investigation and evaluation of the root cause of the failure by vibration data monitoring and material analysis. The objective of the investigation and evaluation is to identify the main root cause and specific symptoms of IDF shaft failure. According to the data collection and analysis result, each phenomenon indicated an identical vibration pattern, however, the duration of each step is different. A series of tests of shaft samples was carried out to get comprehensive information, such as chemical composition test, tensile test, hardness test, microstructural examination (SEM), and fractography examination. The shaft repair procedure was also evaluated. The results were showed that multi initial of micro-scratch and martensitic embrittlement played an important role in the shaft failure. Micro-scratch triggered high-stress concentration on shaft surface. Martensitic embrittlement was found on weld metal and heat-affected zone.

Abstract
On the basis of full compatibility with advanced telecommunications computing architecture (ATCA) standard, micro telecommunications computing architecture (MicroTCA) standard has a evident advantage over ATCA in terms of space, cost and scalability. The MicroTCA standard has become a popular platform in high energy physics. For the advanced mezzanine card (AMC) installed in the MicroTCA chassis, module management controller (MMC) is a prerequisite to fulfill its function. Although there are many MMC solutions, most of their firmware work in polling mode and rarely use the real-time operating system (RTOS). In order to overcome the lack of real-time performance in polling MMC solution, the novel firmware is developed based on FreeRTOS, which is an open source real-time operating system. This firmware implements the basic functions of MMC, such as hot swap, power management, firmware upgrade, and adds the feature of serial command debugging. To verify the difference in real-time performance between the FreeRTOS and the polling solutions, the interrupt reaction time test is carried out on both solutions. The test shows that the average interrupt reaction time of the FreeRTOS solution is about 300 ms shorter than that of the polling method. This result proves that the FreeRTOS-based solution can significantly improve the real-time performance of transaction processing.

Published: March 2021

Abstract
Bank instability as a result of flow fluctuations may lead to massive bank erosions and subsequent damage of adjacent properties. Continuous erosion process promotes change in the river morphology, sedimentation problems due to the presence of secondary currents and local scouring at piers downstream of the erosion point. Knowledge on the extent of erosion should facilitate river engineers to resolve issues on river training works and river sedimentation problems. A study has been carried out in the field to quantify the amount of eroded materials using erosion pins that were driven into the ground normal to the bank surface. The erosion pins consist of 6 mm diameter metal rods and 60 cm – 80 cm in length. A spatial variation profile for rates of erosion has been identified with units expressed in unit cm per day. The defining parameters for bank erosion rates have included near-bank velocity, Ub, water depth, Y, stream bank geometry and soil bearing capacity. Development of empirical equations had used multiple linear and nonlinear regression techniques to determine the significant erosion predictors. It takes into consideration the coefficient of determination (r-squared) and Root-mean square error (RSME) as determinants for best predictors. Accuracy of developed equations is measured using the discrepancy ratio, D.R. This is the ratio of predicted to measured erosion rate. Analysis suggest that the equation derived using polynomial function (order-2) gave better accuracy compared to the equation derived using linear and power functions. An accuracy of 75% has been obtained. Scatter plots of the predicted to the measured erosion rates have shown to be between 0.5 – 2.0 within the line of good agreement.
