Abstract

Air is a layer of gas that covers the Earth. Clean air is air that is free of impurities or substances that can poison the body and is commonly found in areas where there are many plants. The realization is done through a combination of the TGS 2442 sensor on the detector with a high voltage system on the T-Box. The TGS2442 sensor is a high sensitivity sensor to carbon monoxide gas. Thus, the resulting carbon monoxide gas exhaust that has gone through the process will produce oxygen gas because the steel plate on the T-Box functions as a carbon binder. The amount of smoke, which is the output form, is already in the form of ppm, which can be found using the display on the serial monitor and by calibrating using a gas analyzer. The gas analyzer is in the lowest range, namely 100ppm, the sensor detects 116ppm with a percent error of 16%. And when the gas analyzer is in the highest range of 600ppm, the sensor detects 603ppm with an error of 0.5%.

Abstract

Seeing the condition of water availability with good quality which is starting to decrease, it is necessary to have water treatment before the water is suitable for use. Therefore, in this research, a more effective digital measuring instrument is designed to measure water quality in terms of pH and water clarity. The design of tools in the form of natural filtration and pH measuring devices. This study used several water samples, namely rainwater and well water from different locations. Based on the test results, the tool works effectively with a pH value that has been in the standard range from the start (6.5-9) after 4 times of filtration, which is between 6.82-7.60 so that the pH value of the water will be maintained in a condition that is fit for use. . For acidic and alkaline pH categories, it requires repeated processing to get the value according to the standard fit for use

Abstract

The use of electric power is significant to supply water pumps which are usually obtained from PLN electricity. The utilization of electricity from new renewable energy such as solar panel electricity and water turbines has not been used too much to cultivate hydroponic plants. Therefore, combining electric power (hybrid) between solar cells and water turbines is needed to supply electricity on hydroponic technology in conserving electrical energy for the future. Based on these problems, this study conducted various tests to create a design that could be used for energy use in hydroponic plants. The method used includes electrical and systematic design. The steps taken include the stage of literature study, designing, manufacturing hardware, integrating the system, and testing and analyzing the system. These theories can discover solar panels, solar chargers, battery endurance, thief joule circuits, and water turbines. This study uses several tests, including solar panels, solar chargers, battery endurance, thief joule series, and water turbines. Solar panels function to capture sunlight, solar chargers to store electrical voltage to batteries, battery endurance functions to find out how many batteries can store electricity, a series of thief joules to increase voltage, and water turbines to produce voltage. From all data tests, solar panels and water turbines are a source of voltage that the battery will store via a solar charger, and then from the battery, it will be supplied to the hydroponic circuit as a source of voltage.

Abstract

Mathematics is one branch of science that we have learned from an early age. Mathematics is the science of quantity, structure, space, and change. Mathematicians find patterns from rigorous conclusions drawn from consistent axioms and definitions, propose new conjectures, and construct truth. We often encounter a learning approach that becomes a problem in the real world as a context for learning by thinking more critically and skillfully in problem-solving and knowledge and concepts from the material to be learned. The success of learning can be seen from the results of learning. Therefore, learning methods related to technology are indispensable for practical activities with the object of study cannot be separated from theoretical learning. Learning theory makes us bored compared to the practice done directly in front of the computer with existing technology at the moment. One such technology is Web-Based Learning (WBL). Using the Web-Based Learning (WBL) method is expected to help develop its capabilities

Abstract

Currently, there are many Internet of Things (IoT) devices that use Wi-Fi networks to connect to the Internet. As the Wi-Fi network frequency band is used by many parties, the possibility of disconnecting the Internet connection with IoT devices is still high. In this research, we explored the performance of IoT on Wi-Fi networks in high traffic conditions. System testing in this study was carried out using several IoT devices at different distances from the AP. The experimental environmental conditions were also formed so that the Wi-Fi traffic was quite high, generated by software from several laptops. The test results showed that the packet loss in very crowded traffic conditions reached 100%. Round trip time (RTT) data transmission delay of less than 10 ms during normal conditions increased to thousands of milliseconds when the Wi-Fi network conditions were very heavy.

Abstract

At this time, almost all Public Street Lights (PJU) still use the type of mercury and SON-T lamps, even though the mercury and SON-T lamps absorb a considerable amount of electricity. Public street lighting is usually on almost all nights, and this is a waste of electricity. Public street lighting is usually on most nights and thus is a waste of electricity. Usually, when it is past midnight, the streets are quiet, so the street lighting should be reduced in intensity to save electricity.  Based on this problem, this research uses an experimental method (Experiment) to create a design to make efforts in saving electricity. The method used includes electrical and systematic design. The steps taken include the stage of literature research, designing, manufacturing hardware and software, integrating the system, and testing and analyzing the system. Considering these theories, we can know the programming of the microcontroller ATMega 328, Photocell Sensor, PIR Sensor, LED Lights, and Power Supply. This research using several tests, including testing Photocell Sensor, PIR Sensors, LDR Sensors, and LED Lights. Photocell sensor to detect conditions day or night. PIR sensor functions to detect movement, LDR sensor to detect movement, LED lights are used to increase and decrease light intensity. For all the tests above, the results obtained when the PIR and LDR sensors have not detected any movement will dim the intensity of the LED lights. After the PIR and LDR sensors have detected the movement of the LED lights, they will turn automatically bright.

Abstract

In this paper, the efficiency of photovoltaic panels is improved by adding two solar tracking systems. The solar tracking system is used to track the sun so that the photovoltaic always faces the sun. This system uses a dual axis consisting of a horizontal rotation axis and a vertical rotation axis. The motion of the horizontal axis of rotation follows the sun's azimuth angle from north to south. The motion of the vertical axis of rotation following the sun's azimuth angle from east to west is the vertical axis motion. Both types of movement are controlled using PID and Fuzzy controllers which are optimized with an artificial intelligence approach, namely Ant Colony Optimization (ACO). Experiments with PID control approach and CES control were optimized using the ACO method (Hybrid PID-CES-ACO method).   In this research, PID-CES-ACO was the best model, obtained on the horizontal axis of overshot 1328 pu, the smallest undershot was 0.116, and the fastest settling time was 0.183 s, on the vertical axis the smallest overshot was 1.246 pu, the smallest undershot was 0.044, the fastest settling time was 0.163 s
