Published: May 2020

Abstract
Potential Vertical Evacuation Site (PVES) from tsunamis, namely as shelter, is an alternative evacuation solution for the coastal communities in Padang City to people from tsunami despite off to using horizontal evacuation routes. PVES building as evacuation shelter is not identified yet as a proper shelter regarding as structural, management and social impact for safety and it needs recommendation and technical data for better routes and evacuation. The accessibility of PVES’s does not technically measure from the community who will evacuate to it. They just acclaimed as shelter just designed resistant from the earthquake and the location just based on the Tsunami Evacuation Map in 2011 and Stanford University research evaluation for vertical evacuation buildings. The adequacy of evacuation routes to PVES need to be confirmed and have a prior recommendation for surround community how to get there safely. Based on traffic Google Map data create a real-time simulation for people act with their activity and it will project the how they reaction if they need to evacuation to PVES promptly. This study will obtain level of travel time vulnerability, capacity and evacuation ratio for West Sumatra Governors Escape Building as a first building had been built as PVES in Padang City, West Sumatra.

Abstract
Unlike developed countries, traffic characteristics in developing countries are dominated by passenger cars and also motorcycles. For example is Indonesia where more than 70% of transport mode share is contributed by motorcycles and a number of the riders are below age indicating poor law enforcement. This figure is suspected to worsen the transport negative impacts like road accidents as well as congestion level due to poor behaviour of motorcycle riders. Therefore, any efforts to reduce the trip number by mode of motorcycles on the road as well as improving their rider behaviours are necessary. For example is by managing motorcycle parking facilities like in this research. The results of this study suggest motorcycles were used as the primary transport mode for low income people mainly for studying and working. Further, motorcyclists tend to park for long time period with parking areas located about 50 meters from the activity centres. Off-street parking facilities are preferred than on-street parking. These findings are expected could be a considerable contribution for policy makers in minimizing the negative impacts of transport, in particular related to motorcycle usage.

Published: May 2020

Abstract
This Automatic broadcast transmission control is a device that functions to replace a manual switch to an automatic switch with a programmed starting timing process. This device consists of an LED VU Display as an indicator of the voice signal input, a monostable multivibrator as a timer, an Arduino Uno as the main control, and an 8 channel relay module as a substitute for a manual switch. This tool works when the voice signal is active, then relays 1 to 8 will be active, but if the voice signal is off, relays 8 to 1 will be deactivated gradually. On off this channel relay is determined by programmed timing. The results of the experiment show that the active and non-active time of the relay can be programmed in stages with a time difference of 1 second for each relay. Automatic Transmission Control with 8 Relays using Arduino Control is able to automate switching from manual switching to programmable automatic switching.

Published: May 2020

Abstract
Power quality becomes a severe problem due to the increasing use of nonlinear electrical loads, complex electric power systems on smart grids, inverters in renewable power plants, and electronic control equipment. Power quality problems include variations in voltage or current such as sag, swell, flicker, spike, overvoltage, undervoltage, interruption, transient, harmonics, and frequency fluctuations. Research on power quality disturbances mostly applies signal processing and transformation methods such as Fast Fourier transform, S-transform, and Wavelet. In this paper, we use empirical mode decomposition methods and statistical parameters to analyze power quality disturbance signals. It gives more detailed characteristics of power quality disturbances. We conducted a six-step analysis to get a percentage of each power quality disturbance signal. The developed method provides a preliminary description of the power quality characteristics from the percentage values of RMS, range, and energy levels at the first IMF. The positive percentage indicates the existence of power quality disturbances contains flicker and swell, while negative indicates contain harmonics, sag, and transient.

Abstract
Fires of land and forest happened in Riau, give negative impacts to people and its environment. This research discusses about analysis of Wireless Fire Detector as Early Warning System of Peat-land Fire using LM35 Temperature-Sensor, Transmitter-Module(HC-12), Receiver-Module(HC-12), Arduino-ProMini, to produce outputs on LED, LCD, Buzzer. Peat-land fire Detector works when peat land is burning, so its heat spreads through aluminum stem. This temperature is read by Temperature-Sensor1-Temperature-Sensor4. Output of every sensor is sent to each Transmitter-Module(FU1–FU4) in Arduino-ProMini control block. After that, Transmitter-Modules(FU1–FU4) send the readings of sensor to Receiver-Module(FU5). In one time, only one data is received by Receiver-Module from Transmitter-Module. Then, it goes to Arduino-ProMini and processed to get outputs on LCD that display ID of FU1–FU4, Peat-land Status by three activated LEDs, Peat-land temperature. If Green LED is active, means Peat-land not burned. Its temperature is 0°C–21.9°C. LCD displays of SAFE Condition, Buzzer OFF. If Yellow LED is ON, means Peat-land burned underground. Its temperature is 22°C–28.4°C. LCD shows BE-CAREFUL Condition, Buzzer ON. If Red LED is active, means Peat-land burned on the ground. Its temperature is 28.5°C–50°C. LCD displays DANGER Condition, Buzzer ON. This equipment works as its framework.

Abstract
This study aims to model and validate the PM10 concentration from the transport sector and its relationship to the characteristics of traffic, wind speed and wind direction. PM10 was analyzed using the gravimetric method. Sampling were taken twice, with the first sampling carried out at 3 monitoring points representing the different angles of arrival of the wind direction towards the road (α), i.e. 0°, 30° and 60°. For validation, a second sampling was carried out at 0°, 45° and 90° angles. The statistical analysis used correlation and regression tests. Validation tests were carried out using the Pearson Product Moment formula and the Two Variance Test. The sampling results showed that the highest concentration was on a road with an angle of 60° with a concentration of 107.748 μg/Nm3 (number of vehicles 3,219 units and wind speed 0.3 m/s). The lowest concentration was at an angle of 0° with a concentration of 19,298 μg/Nm3 (number of vehicles 680 units and wind speed of 0.98 m/s). Increased traffic volume and density was found to be proportional to the increase in PM10 concentration. Vehicle speed and wind speed have an inversely related relationship with increasing PM10 concentration. There was a decrease in PM10 concentration in traffic volume from α 90° to 60° by 26%, α 90° to 30° by 29% and α 90° to 0° by 61%. There was a decrease in PM10 concentration at the traffic density from α 90° to 60° by 17%, α 90° to 30° by 33% and α 90° to 0° by 51%. The results of the Two Variance Test showed there to be no significant difference in the yield variability between the two PM10 parameter concentrations. This is indicated by the value of the Test Ratio (RUf) being lower than the Critical Point. The validation test conducted using the Pearson Product Moment formula shows that the two equations tested can be declared valid and used to determine the concentration of PM10. This is indicated by the value of R (correlation coefficient) having been calculated as greater than the value of the R table for all parameters.

Published: May 2020

Abstract
The riverbed around the abutment can experience scouring caused by flow, because its is always directly related to river flow. Abutment can obstruct the flow of rivers causing changes in flow characteristics which in turn will cause local scouring around these buildings. Toe Scour around abutment will be very dangerous and cause loss of stability on the bridge. The case of structure failure on Batang Kalu bridge in Korong Pasa Usang Nagari Kayu Tanam, Padang Pariaman Regency on Monday (10 December 2018) is a clear example of toe scouring. A case study of toe scour was on the Batang Kalu River bridge structure has been carried out. Rainfall data closest to the study location, Kandang Empat Station was used to minimize the errors in the calculation of flood discharge design. Numerical modeling with HEC RAS and scouring estimation with some empiric equation was conducted to predicting scour depth on abutment. Simulation results show scour depth results to an average of 2.731 m and close to the scour depth that occurred in the field (2.83 m). Results showed that the local scouring in the Batang Kalu River bridge structure can be suspected as the influence of the increasing river steepness. Discharge that is triggered by heavy rain with a long duration and increased river flow velocity due to steepness has the potential to create a very intense scouring. Increasing of steepness may have been caused by sand mining activities in the upper reaches. Further studies are needed to see the potential slope changes due to exploitation in the Batang Kalu River upper reaches.

Abstract
Heavy equipment in the mining industry is an essential instrument in achieving the company’s production targets. But on the other hand, heavy equipment is complicated and expensive equipment. These problems can be overcome by leasing the equipment to an external agent. In the lease contract between the lessee and lessor, it is discussed about the maintenance strategy of the equipment that will be rented by the lessee. This research presents a real-time monitoring scheme based on multi-sensor data installed on the machine. Case studies from this research were carried out on excavator units in heavy equipment rental companies. The Mahalanobis Taguchi System (MTS) method is used to handle multi-sensor data. Multi-sensor data is grouped into normal condition groups and abnormal condition groups. The variables used to monitor excavator conditions include vibration, pressure and temperature sensors. Based on the results of the calculation of the excavator threshold conditions using the Mahalanobis Distance (MD) measurement technique, the threshold of normal conditions is (-2.137 to 4.121). In contrast, in abnormal accumulator conditions (4, 331 to 39, 458), pump failure (40, 956 to 138, 048), valve failure (2708, 104 to 3404, 187) and the threshold in the condition of the cooler failure is (10736.160 to 11434.151). This research shows that the MD-based CBM scheme produced can detect, identify, and isolate the failure of excavator components under study.

Abstract
Basic Health Research data in 2018 show that around 95.5 percent of Indonesian people less consumption of fruit and vegetables. This condition then leads to the suspicion of vitamin and mineral deficiency in Indonesia people. Several methods have been used to detect vitamin and mineral deficiency, such as convolutional rule-based and certainty factor method. However, these methods are less adaptive to adapt to the changes in symptoms when detecting vitamin and mineral deficiencies. This paper proposes an artificial neural network (ANN) using backpropagation (BPN) to detect the vitamin and mineral deficiencies in the human body. Using 107 input of physical symptoms and 17 output of the type of vitamin and mineral, the architecture of the ANN consist of 107-50-17 neurons for the input layer, hidden layer, and output layer respectively. Based on some trial and error experiments, can be determined the epoch, the learning rate, and the error rate to produce the optimal result of the detection. This experiment using 623 epochs, 0.0517 error rate, and 0.1 for the learning rate. The performance measurement conducted using precision, recall, and F-score, for each class output. The experiment shows the proposed ANN using BPN reaches an accuracy level of 73%.

Published: May 2020

Abstract
The development of systems and technology in the industry especially in the supply chain sector currently has a significant influence on the speed and accuracy along the supply chain. This is one of the reasons to build a container loading and unloading service company located in Surabaya. Terminal Teluk Lamong is the one and only Indonesian company that applies the green port concept with renewable loading and unloading equipment technology. One of the unique and prominent renewable concepts is the docking station, which aims to speed up unloading activities. Because the condition of container unloading activities is more common, this research focuses on container unloading activity only. Currently, the port has five yards available with 30 docking gates on the unloading side. The problem is the yard occupancy ratio (YOR) in unloading activity which has a low percentage value (27%). Even though the percentage value should be around 60%, therefore the value of yard utility didn’t optimal yet. A discrete-event simulation (DES) aims to help classify which yards are suitable for unloading activities and the rest for loading activities. The model verification is obtained “no error” and model validation is less than 5%. For all scenarios conclude that the best scenario is to use three-yard containers with six gates of docking for each yard.
