Abstract

The iodine clock reaction is a chemical reaction that consists of two different colorless solutions mixed into one container to produce a colorless solution and a few moments later the solution turns dark blue. This color change is used as a timer for the stopping mechanism for the chemical-powered car prototype in the Chem E Car team of Universitas Brawijaya. The injection syringe used to inject the iodine clock solution can affect the reaction time of the iodine clock solution due to the difference in pressure at the time of injection so the mixing speed varies. The injection system of iodine clock solution aims to reduce the error of the reaction time of the solution so that it becomes more constant. The system is also equipped with the Internet of Things (IoT) concept which aims to monitor the state of the iodine clock solution such as the temperature of the solution because the competition time is quite long, about 10 hours so that the iodine clock solution must be monitored while not in use. This study uses the YF-S401 sensor as an indicator of the volume of the iodine clock solution. In addition, the system uses an actuator, namely a solenoid valve as a valve for the ex

Abstract

Air pollution from motor vehicle fumes has become a big problem for the environment. The existence of electric vehicles is an effort to reduce the problem of air pollution. However, electric vehicles that use battery resources have a weakness in battery lifetime. To overcome this, we need a system where the battery life when used so as not to run out quickly, namely with a regenerative braking system. Simulation of the regenerative braking system for controlling a DC motor based on fuzzy-PID auto-tuning is a simulation of the regenerative braking system using a bidirectional DC-DC converter and controlling it using auto-tuning fuzzy-PID. This system simulation aims to obtain appropriate control with the system and determine changes in the SOC value of the battery from the resulting regenerative braking. From the system simulation results, it can be seen that the actual speed of the DC motor and changes in the SOC value of the battery can be seen by knowing the value of the performance parameters of the controls made. Index Terms— electric vehicle, regenerative braking, bidirectional dc-dc converter, DC motor, auto-tuning fuzzy-

Abstract

ABSTRACT Screw turbine (Archemedes Screw) is a turbine that utilizes the head and water flow per second flowing in the irrigation channel. This water flow will move the turbine screw. The turbine screw movement will rotate the connecting shaft between the turbine and the generator (producing mechanical energy). The shaft will drive the generator so that the mechanical energy from the shaft will be converted into electricity in the generator. This turbine operates at low speed and is newly developed in Indonesia. But as a new turbine technology, until now there are still very few theories or references available regarding the design of screw turbines. The main components of this power generator are the turbine, speed booster (gear and pulley), Boost DC Converter and battery. In measuring water discharge, the floating method is used to calculate the available water discharge. The electric power generated will be stored in a 12v 7.5 Ah battery. The generator power of the device is designed to reach a maximum point, when the water discharge is 134 liters per second, with a voltage of 5 volts which will be increased the voltage to 12.5 volts and a current of 0.53 Ampere as the battery power supply.

Abstract

This study discusses how to reproduce HHO (Hydrogen Hydrogen Oxygen) gas by water electrolysis process with electrolyzer wet cell or wet type. The method used in this research is experimental. The design of this tool is divided into 3 main stages, manufacture of containers, manufacture of water traps, and manufacture of gas flowmeters. The container measuring 120 mm x 100 mm x 140 serves as a place for the process of separating water molecules (?2?) into its constituent compounds, namely hydrogen (?2 ) and oxygen (?2 ) or it can be called water electrolysis. The electrode used is a graphite with measuring of graphite electrode is 140 mm x 20 mm x 20 mm. 20 grams of Potassium hydroxide (KOH) serves as a catalyst to help accelerate the process of separating water molecules in electrolysis. The container will be connected to a water trap and then a gas flowmeter or gas measuring instrument. This study shows that designing a wet type HHO gas generator with a pure DC source and a PWM source will have a correlation between HHO gas production and variations of the distance between two electrodes. At a distance of 2 cm the electrode produces HHO gas of >1200 ml with a pure DC source within 15 minutes. For an electrode distance of 4 cm the HHO gas produced is 1200 ml with a pure DC source within 15 minutes. And for an electrode distance of 6 cm the HHO gas produced is 880 ml with a pure DC source within 15 minutes. Meanwhile, at a distance of 2 cm from the electrode with a PWM source of HHO gas, the resulting HHO gas is >1200 ml in 15 minutes. For an electrode distance of 4 cm with a PWM source of HHO gas, 1030 ml is produced in 15 minutes. And for the electrode distance of 6 cm with a PWM source of HHO gas, 690 ml is produced in 15 minutes.Keywords: electrolyzer wet cell, HHO gas, distance of electrodes

Abstract

Water quality is the main parameter in the cultivation of freshwater ornamental fish and marine ornamental fish. To get healthy ornamental fish, water conditions must be maintained, one of which is the pH of the water. Generally fish need a water pH in the range of 6.5 to 8.5, which is considered the optimal range for good fish growth. Changes in the pH of seawater can adversely affect the life of marine biota, either directly or indirectly. Controlling the pH of water in marine ornamental fish using the Mamdani fuzzy logic method, by determining its membership function so that it can control the speed of pumping acid or alkaline solutions. From the results of the study, the tool can control the pH of seawater according to the setpoint membership function that has been set, namely 6.5-8.5 for 368-478 seconds by adjusting the pump output discharge according to the difference between the pH of the aquarium and the desired value.Keywords: pH, Fuzzy Logic Mamdani, Membeship Function

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

This study discusses the effect of the hydrophobic layer on the surface of the polyethylene insulator on the leakage current and flashover voltage with variations in exposure to ultraviolet light. This research was conducted by varying the conditions of ultraviolet irradiation on the insulator, test voltage, and also the test conditions in the form of dry and wet conditions. Variations in the duration of ultraviolet irradiation were for 0 hours, 24 hours, and also 48 hours. The insulator used is also divided into 2, an insulator with coating and a non-coating. Initial testing of the contact angle to determine whether the insulator is hydrophobic. Furthermore, distribution simulations and electric field efficiency calculations were carried out using FEMM 4.2 software, so that dielectric strength values could be calculated. After that, leakage current and flashover tests were carried out with voltage variations of 4kV, 8kV, 12kV, 16kV, and 20kV. The results obtained in this study are the greater the value of the test voltage given, the greater the value of the leakage current, while the flashover voltage has an inverse relationship with the leakage current. The greater the leakage current, the smaller the flashover voltage. In insulators with a hydrophobic layer, the value of the leakage current and flashover voltage can be improved. In addition, the addition of the duration of irradiation causes the value of the leakage current to be greater and the flashover to decrease in value.Keywords— insulator, leakage current, flashover, hydrophobic, polyethylene
