Abstract

In the process of hatching eggs in poultry, stable temperature and humidity are needed so that the eggs can develop properly. Poultry eggs, especially chickens take 21 days to hatch with a temperature of 37°C – 39°C and humidity of 50% – 60%. The study aims to produce an incubator that is able to monitor temperature and humidty based on arduino microcontrollerswith an internet of things (IoT) system and determine the stability of temperature and humidity values in the incubator. Test were carried out by incubating 6 eggs in an incubator with the result that 5 eggs hatched perfectly and 1 other egg did not develop properly. The conditions of temperature and humidity during the hatching process are classifed as stable, namely termperatures between 37.34°C – 38.34°C and humidity between 52.80% – 56.40%. The system is able to read and send the readings of temperature and humidity sensor values to the Blynk aplication properly.

Abstract

Noise can be reduced by using materials that can dampen and absorb sound. Sound absorbing materials have an important role in room acoustics. This study aims to apply egg trays to the walls of MTs Islamiyah Tanjung Kasau classrooms. The study was conducted by measuring the noise level before and after the implementation of the egg tray on open and closed doors and windows in the MTs Islamiyah Tanjung Kasau classroom at 20 different points. The source of the sound comes from the sound generated by the activity of vehicles on St. Sei Langgei Perk Village. Tanjung Kasau during school operating hours. The tool used to measure noise levels in this study is a sound level meter (SLM). Data processing uses Surfer Golden V16 Software to create a contour map of sound distribution. The noise level generated in the classroom before the implementation of the egg tray when the doors and windows were open and closed was 61.39 dB and 59.41 dB. These results did not meet the standards in accordance with KEPMENLH No. 48 of 1996 concerning the Noise Level Standard for Schools, which is 55 dB. Then an acoustic absorbing material was added to the classroom using egg tray material to reduce noise in the MTs Islamiyah Tanjung Kasau classroom. The noise level after the application of the egg tray in open condition is 53.47 dB, in closed condition is 49.99 dB.

Abstract

Indonesia is a tropical country whose renewable energy sources have not been optimally explored and developed. The advantages of a tropical climate are rain and heat, which should be put to good use to become a renewable energy source. One of the beneficiaries is the energy produced by rainwater using piezoelectricity. With the pressure of rainwater on the piezoelectric, the piezoelectric can produce electrical energy that can be stored for use. The amount of energy that can be generated directly depends on the piezoelectricity used and the rainfall. The method used in this research is to do experimental testing. The generated electrical energy is stored in a 12 V dry battery which has been rectified from AC (alternating current) to DC (direct current) using rectifier diodes. The results of the electrical input voltage are processed using the Arduino Uno microcontroller via a voltage sensor and stored using a data logger shield with an SD card and data. The results of this study show that the largest voltage and current are generated at 110.5 mm rainfall and a voltage of 35.50 V and a current of 209.95 mA is obtained. While the smallest voltage and current are generated at 9 mm rainfall and obtained a voltage of 2.89 V and a current of 17.1 mA.

The purpose of this research is to find out how to design and build a flood early warning system so that it can be connected to the internet network can directly send information, design the Blynk application so that it can receive information, and to find out the flood early warning system that has been built using solar panels. The design of an internet of things-based water level monitoring tool using the blynk application requires several components, namely, arduino uno wifi, ultrasonic sensor HC-SR04, buzzer, led, LCD, Brushless pump dc, and solar panels. The results of measuring water levels using the HC-SR04 sensor have a low error rate with a comparison of the HC-SR04 sensor with a ruler of 1.97%. The time it takes to send the sensor reading notification is 4.42 seconds. A flood early warning system that is connected to the blynk has been realized, marked by the success of the system in measuring water levels and being able to send notifications to the blynk with the right size and status. There is also the average time of sending messages or data to the blynk application in all conditions using arduino uno WiFi is 4.42 seconds. From the results of testing data on solar panels without a load and using a load, the voltage and current of the solar panels are influenced by weather conditions, if the weather is cloudy, the voltage and current generated by the solar panels will decrease.

Abstract

Garbage is one of the biggest problems faced by many cities in the world, the lack of awareness to dispose of waste in its place causes waste to scatter and pollute the surrounding environment. This research aims to design an automatic trash bin based on the Arduino microcontroller and to find out how the automatic trash can works with the HC-SR04 ultrasonic sensor based on the Arduino Uno microcontroller. The design of this system uses Arduino Uno. The results of the input and output tests show that the HC-SR04 ultrasonic sensor has a low error rate of 1.2% at a distance of 25 cm and a high of 6% at a distance of 10 cm. The trash can opens the lid automatically at > 30 cm to detect the capacity of waste that has been disposed of into the trash container with a height of 20 cm., the proximity sensor will detect the type of waste being disposed of, and the LCD will display the type of waste that will be disposed of and the servo motor will activate the mechanical system of this device. If the trash can is full, a warning will be sent via the buzzer and the SIM800L GSM module via SMS. The working system of the automatic trash can as a whole can work well according to the design that has been made.

Abstract

Coffee is one of the plants that is widely cultivated in tropical countries such as Indonesia. Coffee plantation commodities at least contribute a lot to the Indonesian economy, which creates foreign exchange, farmer income, industrial raw materials, employment, and regional development. This research aims to design coffee bean dryer equipment using a heater as a heating element instead of sunlight for the process of drying coffee beans. When the temperature has reached 60°C, the heater will turn off briefly, and if the set time has not expired, the heater will always be alive. If the humidity does not decrease, the fan will fail. In this research, using experimental research procedures where each measurement is used effectively by each sensor so that the measurement results of each sensor are accurate. From the test results, it can be concluded that the initial weight before drying was 1000 grams, while the weight after drying was 880 grams.

Abstract

The problem that people often face, both at home and in public places, is noise that disturbs concentration and comfort. Noise can be measured by sound level measurement, namely by measuring the intensity or loudness of sound in hertz and sound waves in decibels (dB). Then noise can be reduced by materials that can absorb sound, one of which is glass wool. The purpose of this research is to make a noise-measuring instrument, find out the effectiveness of damping materials, and compare the results of measuring noise levels. The measuring instrument for noise in this study is the sound level meter (SLM) using a KY-037 sound sensor programmed with Arduino Uno as a microcontroller. The results of noise measurements using a factory standard SLM and noise measurement tool KY-037 obtained an average factory standard SLM measurement of 72.23 dB and the average measurement of the KY-037 noise meter is 67.67 dB. From the measurement results with the two tools, the difference in comparison is 4.56 dB with a percent deviation of 6,33%. Then the results of testing the glasswool sound-dampening material with a comparison of the two measuring devices obtained that each sound intensity absorption was 17.9 – 28.5 dB and the effectiveness of the reduction was 21.8% – 34.9%.
