Abstract

Ornamental fish is one of the major export commodities, besides that, there are also many domestic marine ornamental fish hobbyists. The maintenance of seawater ornamental fish needs to pay attention to the level of salt or salinity so that the fish can survive. Manually adjusting the salt level of seawater is not efficient and must be checked continuously. Therefore, an automatic salt level controller is needed. In this study, the sensor design process was carried out using the YL-69 sensor and pump speed regulation. From the results of this study, it can be seen that the tool can balance the salt content according to the setpoint membership function fuzzy, which is 32-37 ppt for 564-768 seconds. The water discharge coming out of the pump can also be adjusted according to the difference in the salt content of the aquarium with the desired value.Keywords: Salinity, fuzzy, membership function.

Abstract

Aquaponics is a system of cultivating fish (aquaculture) and plants (hydroponics) together in a circulated/mutually beneficial ecosystem that uses natural bacteria to convert fish feed waste & residues into plant nutrients. Aquaponics aquaculture innovation is considered to play an important role in meeting the needs of fish and vegetables in the market. In addition to being economical, the potential of aquaponics cultivation can be a reserve for fish and vegetable needs in waters and rice fields. Water quality is a key parameter in aquaponics. To get optimal results, water conditions must be maintained, one of which is the pH of the water. The degree of acidity of the growing media and the sangan water affects the growth of fish and plants in aquaponics. If the pH level is too low or too high, it can interfere with the growth of fish and plants. The implementation of the fuzzy logic control method mamdani on controlling the pH of the water is a way to maintain the quality of the water in the aquarium, especially the pH so that the growth of fish and plants is optimal. Controlling the pH of water in aquaponics using the mamdani fuzzy logic method, by determining the membership function so that it can control the volume output of the pH up solution or pH down solution so that the pH of the water in aquaponics remains neutral. From the results of the study, the tool was able to control the pH of water in aquaponics in accordance with the desired membership function setpoint, namely 6.5 -7 with an average error of 0.14% regulating the output of the pH up and pH down solution volumes with the desired value.

Abstract

Water quality is one of the factors that must be considered so that the aquaponic system runs well. One of the important parameters in maintaining water quality is the degree of acidity (pH). Therefore, it is necessary to monitor and control the pH regularly. Control is carried out by adding a buffer solution to the aquaponic pond using a pump motor. Poor water pump performance can result in the incorrect addition of buffer solution according to the required calculation. Controlling the output volume of a mini water pump motor using the Sugeno fuzzy logic method aims to control the volume released according to predetermined calculations. From the research results, the system is able to control the pump output volume according to several predetermined setpoints, namely 25–350 mL with a maximum error steady state of 1% within 1.5–11.8 seconds by adjusting the speed of the pump motor according to the desired amount of solution.Keywords: pH, Fuzzy Logic Sugeno, mini water pump, setpoint

Abstract

Water quality is one of the main parameters in the aquaponic cultivation of tilapia and mustard greens. To produce tilapia and mustard greens that are healthy and fresh, the condition of the water in the aquaponics system must be maintained, one of which is the pH of the water. Tilapia and mustard greens require a pH range of 6 to 7, which is the optimal pH range for the growth of tilapia and mustard greens. Changes in the pH of aquaponic cultured water can adversely affect the lives of tilapia and green mustard, either directly or indirectly. Controlling the pH of water in aquaponic cultivation using the Sugeno fuzzy logic method involves determining the membership function so that it can control the administration of pH up (alkaline) and pH down (acidic) solutions. From the results of the study, the tool is able to control the pH of aquaponic aquaculture water according to the setpoint membership function that has been set, namely 6-7, and in several volumes of aquaponic cultivation ponds with a solution output of pH up and pH down according to the desired pH of aquaponic cultivation ponds with an error of 2.7%.Keywords: pH, Fuzzy Logic Sugeno, Membership Function, Volume, pH Up, pH Down

Abstract

A thermal camera can function well in various environmental conditions with low visibility and high contrast. Thermal cameras can be used to identify objects through semantic segmentation. The image obtained by the thermal camera on the Autonomous Electric Vehicle (AEV) can be used to segment the location of cars, roads, trees, buildings, etc. at each pixel. Fully Convolutional Network (FCN)-ResNet-50 is one of the ResNet models that can be used to segment roads. The results of the AEV route segmentation are then used to determine the steering direction. The process takes place by utilizing the OpenCV library to determine the Region of Interest (ROI), changing the HueSturation-Value (HSV) value. This process is used to change the road segmentation to white, while the other segmentation will change color to black. Because the white color has a value of 255, andthe black color has a value of 0, it can be calculated and obtained as a comparison of the values of each pixel of the road segmentation image between the right and left sides of the road segmentation image. From the research results, the guidance system through determining the direction of the steering based on the results of road segmentation using the results of deploying the FCN-Resnet-50 model was successfully carried out through several stages, such as determining the Region of Interest (ROI), changing the Hue-Sturation-Value (HSV) value, etc. The error in giving steering recommendations is caused by the FCN-Resnet-50 model used which still has a lot of segmentation faults.Keywords: Autonomous electric vehicles, Guidance System, FCN-Resnet-50, Steering, Semantic Segmentation

Abstract

Hydroponics is a method of cultivating plants without using soil media. Hydroponics utilizes water/nutrient mineral solutions needed by plants and other materials as a substitute for soil media. Plants need the right amount of nutrients to grow and develop optimally. This research aims to design a tool that can provide the number of nutrients automatically with nutrient levels that can be adjusted remotely with the concept of the Internet of Things. The control system used is Mamdani fuzzy logic withinput offsets for nutrient content and water level in the reservoir, as well as output for the duration of the nutrient and water pumps to reach a setpoint that can be determined via the Blynk IoT platform. The results showed an accuracy of 93.14% for nutrient control and 97.83% for water level control in reaching the setpoint. Keywords: Fuzzy Logic, Hydroponics, Internet of Things, Nutrition Control System.

Abstract

The performance of PEMFC is highly dependent on the level of oxygen supply to the cathode. The diffusion rate of oxygen through the cathode catalyst layer is influenced by factors such as the thickness and porosity of the layer, the oxygen concentration in the gas flow, as well as the temperature and pressure of the fuel cell. The level and quality of oxygen supply to the cathode play a crucial role in the fuel cell's performance. This research will discuss the analysis of the influence of increasing oxygen supply by increasing the oxygen content to the cathode and examine its effects on the performance of the Open Cathode PEMFC. This study utilizes a specialized system to support the measurement and reading of oxygen content values in the air using an oxygen sensor, as well as automation using a solenoid valve from a pure oxygen gas cylinder to achieve optimal oxygen content for the performance of the Open Cathode PEMFC. The research will be conducted by performing several experiments to increase the oxygen content in the vicinity of the fuel cell, which has been provided with a box-shaped space with a constant flow of hydrogen gas pressure into the fuel cell. Then, a hose will fill the space with pure oxygen gas mixed with ambient air from an air compressor to obtain the desired oxygen content value. The pressure of the oxygen gas and ambient air from this compressor is controlled by a solenoid valve. Subsequently, the voltage, current, and power output of the fuel cell will be measured from several experiments of increased oxygen content, which will be read using an oxygen sensor.

Abstract

Fuel cell is one of the environmentally friendly renewable energy generators. The fuel cell requires oxygen and hydrogen which act in the membrane so that it can generate electricity. The results of the reaction that occurs in the fuel cell are electricity, heat and water so that it is more environmentally friendly. However, as a generator of renewable electrical energy, fuel cells have several drawbacks, including the need for balanced oxygen and hydrogen pressure, proper working temperature and proper humidity in order to maintain the performance of the fuel cell itself. This fuel cell stack requires optimal humidity in order to maintain the performance of the fuel cell itself. An external humidifier is one of the solutions to keep fuel cell moisture in order to make its performance more efficient. In this study, a humidifier system is applied which utilizes vibrations from an ultrasonic humidifier to convert water into a gas phase and a fan as a medium for transporting water vapor to the fuel cell. Water in the gas phase will mix with the surrounding air which will be absorbed by the open cathode fuel cell. In this system, DHT 22 functions as a moisture detector around the fuel cell as feedback so that the controller can maintain the ambient humidity value.

Abstract

The parking area at Universitas Brawijaya which functions as a vehicle storage place for students and the academic community is often used by people outside UB because the condition of the portal in and out of the parking area is always open. In full parking conditions, students must enter the parking area to check the parking quota because there is no information on parking availability and this causes mobilization in the parking area to be disrupted. To overcome this problem, it is necessary to create an RFID-based smart parking monitoring system that functions to scan RFID tags as a condition for opening portals and parkingarea access. In this smart parking system, testing is carried out using a design (prototype) that is in accordance with actual parking conditions. The parking system is equipped with an RFID reader, servo actuator that functions as a portal, seven segment display as parking availability information and ultrasonic sensors as distance detection to close the portal. From the results of the study, the tools made are able to work according to the expected functions. Information on parking availability on the display is 100% in accordance with actual conditions, RFID reading positions are most effective at an angle of 90º with a maximum reading distance of 4 cm. RFID readers are capable of reading RFID tags a maximum of 2cm in the state where the RFID tag is in a wallet. The ultrasonic sensor in this study works with a maximum distance of 25 cm.
