Abstract

This study aims to test the performance of fuzzy logic in the gasification process. Gasification is the process of converting solids into flammable gases. The gas produced becomes an alternative energy source, namely the Waste Power Plant (PLTSa). The research applies Mamdani's Fuzzy logic. Fuzzy logic was created using Matlab R2018b software. The results obtained indicate that the Mean Absolute Error (MAE) output of H2 on fuzzy logic training data is 6.57. The test results for CO fuzzy output MAE value of 1.12. The test results on CO2 MAE fuzzy are 1.18. In the CH4 test, the MAE fuzzy output is 0,84.

Abstract

The wind speed gauge in a wind tunnel plays an important role in the airflow simulation process so that it is similar to the actual conditions as desired. Wind speed measurement in wind tunnel mostly use manometer with special fluid (red manometer fluid) and the resulting data is in the form of analog data. The red manometer fluid is unavailable in Indonesia and its price is quite expensive so it becomes a challenge for wind tunnels that still use manometer. Therefore, it is necessary to make a new instrument for measuring wind speed that is easy to use by utilizing materials that are easily obtained but still apply the same measurement principles as a manometer in measuring wind speed in wind tunnels. The design of the wind speed measuring device can take advantage of microcontroller technology. The wind speed sensor design process goes through three stages including hardware design, software design, and system design. The hardware used for the system are an Arduino Uno R3 microcontroller, a differential pressure sensor MPXV7002DP, and an LCD. Research results obtain a wind speed sensor that can be used to measure wind speed in a low subsonic wind tunnel based on Bernoulli's principle that utilizes a pitot tube with a maximum speed of 30m/s. The wind speed sensor is an Arduino-based design that can display the wind speed measurement results on the LCD screen. The wind speed sensor was declared valid to be used to measure wind speed because there were no deviations from the wind speed measurement when compared to the measurement results from a calibrated anemometer.

Abstract

Along with the progress of the times and technology is currently increasing the number of motorized vehicles on the highway. However, this increase in the number of motorized vehicles is not matched by an increase in road volume capacity, causing traffic congestion. The purpose of this study was to find out information about traffic conditions at highway intersections. This research is a prototype that describes a four-way intersection that has infrared sensors in each path. This infrared sensor is used as a vehicle detector. Tests on the prototype made various traffic conditions that are relevant to the actual situation. This research utilizes the concept of the Internet of things (IoT) prototype which is made to be connected to the internet network so that users can find out traffic conditions remotely and in real time. One of the information media used in this research is Twitter. The results of this study indicate that the prototype made can work well. The infrared sensor used can work optimally and can detect vehicles precisely at a sensitivity range of 4.5 cm. The average delay in sending notification tweets is 18 seconds.

Abstract

The application of Internet of Things (IoT) technology will be one of the technologies that complements all fields along with the increasing use of smartphones. The purpose of this research is to design an on-off control system for lights and servo motors as door latch actuator based on IoT. The designed system can give commands on/off the lamp or door latch actuator and display the on/off indicators through an application on an Android smartphone. The system is designed using a Wemos D1 mini microcontroller as a processor, light sensor, infrared sensor, relay, servo motor, and RemoteXY app. Based on the test results, the system design has been successfully implemented and can be operated as an on-off controller via the internet with an Android smartphone. For each test performed, the system managed to provide an output that matches the given control input. The response time (delay) of the relay when on or off the lamp about 34,83 ms while the response time of the servo motor when opening and closing the latch takes about 38,93 ms. The notification shown corresponds to the state of the lamp and the state of the latch.

Abstract

One of the main sectors that uses the largest electrical energy in a country is the commercial sector. One of the parts of this sector is education. This sector has a sub-sector. It is called a building. Electrical energy conservation efforts are needed to streamline electrical energy consumption by looking at energy-saving opportunities. This research was conducted at Halim Building and Wiweko Building in Institut Teknologi Dirgantara Adisutjipto (ITDA), Yogyakarta. The research was conducted by taking energy audit data regarding the level of electrical energy consumption as seen from the Energy Consumption Intensity (IKE) parameter. The research method began with the data collection. Furthermore, the data were processed using Ms. Excel, SPSS, and Matlab. Statistics analysis with ANOVA was carried out to conclude what parameters affected IKE. The results showed that the IKE value of the Halim Building was 30,48 kWh/m2/year and the IKE value of the Wiweko Building was 24,16 Wh/m2/year. The IKE value was still significant in the efficient category following   ESDM & JICA Electric Power Development Co. LTD standards.

Abstract

Load imbalance that occurs continuously will decrease in the reliability of a system, the maximum limit for load imbalance, according to IEEE  Std 446-1995 is 20% in each phase. The design of a prototype for the management of 1-phase loading electrical energy using the Blynk platform as a user interfaces, monitor and controller. The phase shift method reduces the percentage value of the load imbalance in the electrical energy distribution system. An Energy Meter is used for measuring the electrical quantities and detecting unbalanced phases. Arduino Mega and ESP 8266-01 are used to communicate data as sending and receiving commands from Blynk, testing before balancing the measured load on the Energy Meter. The R phase has a current of 0.36 Ampere, The S phase is 0.71 Ampere, and 0.00 Ampere in the T phase. The percentage before load imbalance shows a value of 100%. After balancing the load, the measured current becomes 0.41 Ampere in the R phase, 0.44 Ampere in the S phase, and the 0.39 Ampere for T phase. The value of the load imbalance decreased to 17.7%.

Abstract

The high content of harmonics in an electric power system can cause several disturbances to the system, such as increasing power losses in the system, causing various damage to electrical equipment, and causing the use of electrical energy to be ineffective. Harmonics is caused by the operation of non-linear electrical loads. The interacting harmonic currents with the supply system impedance distorts the supplier's output current and voltage which in turn adversely affects the loads connected to the system and the supply itself. This study aims to analyze the quality of THD in Bubung Tujuh Hamlet, Sangku Village. In this study, THD measurements were carried out and analyzed the effect of harmonics on the power factor using a linear regression test. The results of the measurement and analysis of THDV ranged from 1.0% - 6.8%, with the final analysis of THDV still meeting the set standard of 5%. THDI ranged from 2.3% - 66.7% with the final analysis THDI did not meet the standard. THD of the village's electrical system is still at the standard limits set and THD(V) effect on PF.
