Abstract

Increased noise caused by human and industrial activities can cause health problems, such as stress, affecting sleep quality, and having negative effects on long-term health, usually such as hearing problems, high blood pressure, and depression. This study aims to make a noise-measuring instrument, examine the comparison of the results of sound intensity level measurements, and examine the damping ability of polyurethane. The sensor used in this study is the FC-04 sound sensor which functions as a sound intensity level meter that works by changing the sound scale to an electrical quantity. The data that has been obtained is a comparison of the measurement results using the factory standard sound level meter (SLM) and an artificial noise measuring instrument which is analyzed using the calculation of the percent deviation. As for the measurement data of the damper material polyurethane before and after, analyzed using reduction effectiveness calculations. The results of measuring the sound intensity level using the factory standard SLM and an artificial noise meter obtained an average value of the sound intensity level of 72.67 dB and 67.77 dB. From the results of the two measuring instruments, the percentage deviation of the measuring instrument is 6.7% with minimum and maximum percentage deviation values of 3.1% and 11.7%. The results of the measurement of the reduction effectiveness value of the damper material polyurethane using factory standard SLM and artificial noise measurement tools of 14.7% and 14.8%.

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%.

Abstract

Jeruk madu merupakan tanaman yang banyak dibudidayakan di negara-negara yang memiliki iklim tropis, termasuk negara Indonesia. Salah satu daerah yang banyak membudidayakan jeruk madu itu terdapat di daerah Berastagi, Sumatera Utara. Untuk pemilahan buah jeruk madu yang akan diproduksi masih digunakan secara manual dengan bantuan manusia dan memakan banyak waktu. Seiring berkembangnya teknologi, maka diciptakanlah alat pemilah buah yang bisa membedakan warna, bentuk, ukuran dan berat. Dengan alat sortir buah yang berbasis arduino uno yang akan mengontrol sensor TCS3200, sensor Load Cell dan juga sensor Infrared, akan menghasilkan alat sortir buah jeruk madu yang akan memilah berdasarkan warna, massa dan menghitung jumlah buah yang disortir. Dimana jeruk madu yang akan disortir dengan alat ini memiliki 4 keadaan, yaitu jeruk madu hijau berat, jeruk madu hijau ringan, jeruk madu kuning berat dan jeruk madu kuning ringan. Hasil pembacaan dari pemilahan warna TCS3200 yang berupa nilai RGB dari setiap buah dan hasil pembacaan sensor load cell yang memiliki deviasi rata-rata sebesar 0,52%.
