Abstract

There are still many uses of transportation means to move goods manually, even though there are many shortcomings in it. One of the drawbacks is that the push button must be continuously pressed by the operator until it reaches the desired place, this of course will take a lot of time and full concentration from the operator himself. In this final project, a prototype design of an Arduino Uno based automatic metal conveyance is designed to be able to move goods automatically. The design of the prototype for automatic metal conveyance based on Arduino Uno uses the infrared avoid obstacle sensor as object detection, DC motor as the main driver for moving goods, and uses LD micro software. The working method of the prototype design for this automatic metal transportation device based on Arduino Uno is when the automatic switch is turned on, the DC motor 1 works to transport the drum containing metal vertically (up and down) to the infrared avoid obstacle sensor, then the DC motor 2 will work horizontally (forward -back) heading to tubs 1, 2, and 3 to move metal automatically. Based on the test results that have been carried out, the design of the prototype automatic transportation tool based on Arduino Uno has a difference in the duration of time to transport metal with different loads, namely, if without load the time needed to transport goods is 94 seconds, with a load of 36.5 grams is 101 seconds. , and with a load of 111.1 is 103 seconds, with a time difference from no load to a load of 111.1 grams is 9 seconds.

Abstract

Renewable energy is energy that comes from natural elements and its availability will not run out because it is formed from sustainable natural processes. Renewable energy is an alternative energy to replace fossil energy because it is environmentally friendly and does not produce carbon emissions. Renewable energy sources come from sunlight, wind, water flow, geothermal, etc. One of the renewable energy potentials in Indonesia is wind energy with a total potential of 60.6 GW. Utilization of wind energy can be done by using wind turbines and windbelts to convert wind energy into electrical energy. Windbelt is a device consisting of a permanent magnet, coil and tape to produce electrical energy. When the oscillating band is blown by the wind, the magnet produces a change in magnetic flux, then the magnetic flux captured by the coil produces induced emf at both ends of the coil. In order for the power generated by the windbelt to remain at its maximum point even though the wind speed fluctuates, a Maximum Power Point Tracking (MPPT) system is needed. Therefore, in this study, an MPPT system was designed using the Perturb & Observe (P&O) algorithm by controlling the length and tension of the band based on the windbelt output voltage. The optimal voltage generated by the windbelt is 8.93 Volts without using the MPPT system, while when using the MPPT system the optimal voltage is 5.05 Volts. In testing the MPPT system using a load (condition 2), the output voltage has decreased drastically because the current generated by the windbelt is so small that it cannot pass through the load.

Abstract

Neutralizing household wastewater into clean water is currently one way to reduce groundwater use. In this final project, a neutralization system will be designed for residential wastewater into clean water. This system consists of, water level sensor, water ph sensor, microcontroller, pump, . Wastewater from each house is channeled into a holding tank. If the waste water reservoir is full and the clean water reservoir is empty, the wastewater from the reservoir is channeled into a water treatment tank to be processed into clean water with a pH value of 7 to 9. achieved. Meanwhile, if the waste water reservoir is full and the clean water reservoir is also full, the clean water can be channeled for the needs of the residents or flowed into the river. With this concept, residents' need for clean water from ground water can be reduced and the water discharged into the river is also clean water that does not pollute the river. The energy source for power supply to the system comes from solar energy which is stored using batteries. The process of neutralizing wastewater with injection / addition of aluminum sulfate / alum (Al2OH) and aluminum chloride (PAC) as much as 9 mL is able to raise the pH from 4.3 to 7.81 so the results have met the water quality standard.

Abstract

Chili plants really need to be considered both in terms of planting or watering, but they really need a place that has good soil levels and an ambient temperature that is not too hot or cold. If these plants can be watered automatically, it is likely that the quality of the plants will be good and will get good results. This study aims to design an automatic watering device that will be monitored remotely so that soil moisture is maintained. Where this final project has designed an automatic watering device and keeps the temperature inside the Green House automatically based on IoT and a monitoring system based on several prototypes controlled by Arduino mega2560 and NodeMCU ESP8266 as a data sending tool and connecting to Thinger.io which functions to display data, the pump will active to water the plants when the sensor value reading is above or more than 70% and the pump will stop when the sensor reading value is below or more than 50%, then the fan will turn on when the temperature value inside the green house is more than 28 degrees Celsius and the fan will turn off when the temperature value inside the green house is less than 28 degrees Celsius. The Soil Mousture sensor functions as a reader of the humidity value in chili plants and the DHT11 sensor as a reader of the temperature value in the Green House. Based on the TIPHON standard, QoS testing of monitoring system communications is included in the good category, for throughput testing the index value is 4, packet loss index value is 4, delay index value is 1, and jitter index value is 1.

Abstract

The laboratory has information that must be updated frequently to provide students with information regarding the presence of laboratory assistants. Therefore, in this study, digital signage will be used as an information medium that can display laboratory assistant presence data in real-time. Through digital signage, laboratory assistant presence information can be displayed digitally and accurately. The initial step of the program is to initiate the database. After the E-KTP is attached to the RFID, the database will check whether the identity on the card is recognized or not. If the card is registered on the attendance form, it will be displayed on digital signage. Based on the test results, the use of digital signage as an information board based on RFID as a method of identifying the presence of laboratory assistants has given good results. This system can display real-time and accurate attendance information through digital signage. In addition to testing the duration of the RFID reading when exposed to obstacles in the form of plywood and acrylic and when not exposed to obstacles, it shows variations in reading duration depending on the surrounding environment of the RFID reader. Furthermore, Quality of Service (QoS) testing was carried out, which showed very good results according to TIPHON standards. The test results show the lowest delay in the morning using a tethering network with a value of 11 ms and the highest throughput in the morning using a tethering network with a value of 736.649 bits/s. Packet loss and jitter are 0 each time.

Abstract

A flood is a natural disaster that occurs due to high rainfall and causes the overflow of rivers or streams that cause many losses to humans and can be an impact that causes electrical short circuits. This can certainly lead to harm such as injury, injury, even loss of life. In certain areas, many are still affected by flooding, especially in Jakarta and its surroundings. Many measures taken to deal with flooding have not been sufficiently effective, but few have cared for their own safety in the face of the effects of flooding. In this final assignment he designed a prototype model of an automatic power cutting system for flood disaster response homes. Designed on a 1:10 scale system with a height of actually 200 cm. Prototype models are made for simulation testing to facilitate the system in testing. The system consists of an ultrasonic sensor, an MCB, a servo, a traffic light indicator in the form of a light, a buzzer in the form of a sound, and an LCD 16x2 as a display of the sensor readings. The process in the system with the reading of the distance of the water surface uses the HC-SR04 ultrasonic sensor to produce a high value of water with the calculations on the program. And the calculation for the accuracy of the ultrasonic sensor readings uses the RMSE (root mean square error) formula and gets an RMSE value of 0.20 - 0.95 Cm where 0.20 Cm is the lowest RMSE value at 15 Cm water height and 0.95 Cm is the highest RMSE value at 10 Cm water height. The working principle of the system is to read the distance of the water surface to produce a high value of water, the high value of water is divided into 3 statuses, namely safe at a height of 0-7 Cm, alert at a height of 8-14 Cm, and flooding at a height of 15 Cm. At a height of 15 Cm and declare the flood status results that cause automatic power breaks.. Keywords : Fresidential flood, ultrasonic sensors, prototype model
