Abstract

We has been successfully creating a laboratory security system prototype based on Arduino Mega. This device assisted with PIR sensor (passive infrared) and RFID (Radio Frequency Identifier). In experiments carried out study the sensitivity of the PIR sensor at a distance of 0 meters, 0.5 meters, 1 meters, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 3.5 meters and 4 meters then at an angle of 00, 300, 450, and 600 with the source of motion is the human’s body movement. In this study data showed that at a distance of 2 .5 meters at an angle of 60 degrees PIR was not able to catch the source of human movement. At a distance of 2.5 meters below and 60 degrees could not catch the source of human movement. Otherwise at a distance more than 2.5 meters human movement can not be captured by the PIR sensor. At the RFID trial data obtained that the card can be read by an RFID reader within a maximum of 3 cm, with no barrier between the RFID reader and the card. The data condition also occurs when a thick paper is placed between the card and RFID reader as a barrier. While at the moment given the barrier is made from plastic the card can be read at a distance of 1 cm maximum. Keywords: Arduino, ATmega2560, Passive Infra Red (PIR), Radio Frequency Identifier (RFID), Security system.

Abstract

The water level detection sensor is a major component on flood early warning system. HC-SR04 Ultrasonic Sensor is usually used as a proximity sensor in a flood early warning system. The accuracy of the sensor is essential to support the effectiveness of a system. In this research, the calibration of HC-SR04 ultrasonic sensor using arduino microcontroller, which is it will be used on the prototype early warning system for floods. Calibration is done by taking reference to the warning status I, II, III, and IV of the Katulampa dam. The results showed that both sensor calibration can work well in the range of 14-250 cm, with a maximum relative error of 4.3%. The smallest change in distance that can be detected by the sensor by 1 cm with a maximum relative error of 0.91%. With the errors obtained, it can be said that the sensor is fit as a detector of the water level in flood early warning system prototype in 1:5 scale. Keywords: Ultrasonic Sensor, Arduino, Warning Status.

Abstract

This study used TCS 230 as color sensor to create colors’ album by identified output frequency of TCS 230 and measured RGB value for each color. TCS 230 converted light to electric signal by wave frequency. By using colored paper and facing to TCS 230, the LabVIEW presented its RGB value. From measurements taken, it appears that the sensor have been able to read the color, not just the primary colors (RGB) but also its derivatives. Sensors indicate that despite differences derived by naked eye color and RGB composition has only minor differences, the fixed sensor is capable of capturing the difference even though there are still errors. The amount of the average error for the color red and its derivatives is 28.0336%, while the average error in the measurement of derivatives and their blue color is 38.96% and the average error in blue and derivatives amounted to 32.99103%. Keywords:RGB,TCS 230, labVIEW, colors’ album.

Abstract

The main problem on solar energy is instability power which generated by the solar panels, because it depends on the sunlight intensity which accepted by the solar panels. The intensity of sunlight received by the solar panels can be maximized by installing solar panels with a right angle so it will be obtained the maximum output power. This study has been carried out optimization angle of the solar panels that will be used on the active prototype solar tracking system. The optimization is taking the theta (θ) angle on the x negative axis by using the angle 0ᵒ, 30ᵒ, 45ᵒ and 60ᵒ. The results showed that the average ouput power of the solar panels began to decline at 45ᵒ. To find the best angle we tried to set the optimization at 10o, 20o, 25o, and 40o. Based on these studies an maximum average power output is 73.17mW at the angle of 25o. Key words: solar panels, sunlight intensity, tilt angle, active solar tracker.

Abstract

Rebana/tambourine is a traditional musical instrument which is consist of many kinds. Rebana/tambourine was designed manually and received by the manufacturer with a sense of spirit and their own feelings based on their experiences. Human’s sense of hearing can distinguish between high and low tones, but cannot know surely what kind of tone was heard by them. It is very important for a musician to know whether the instrument is already generating correct tones. Because of that, this research was conducted to analyzed the characteristics of sunds frequency in tambourine/rebana. Tambourine/rebana is traditional musical instrument that do not have a standard tone yet as other musical instruments. Each tambourine generated has a difference in each of her tuning. So, it is hopefully that results of this research can be used to decide the standard of tambourine/rebana musical instrument. This research was conducted used software based on android that is android mobile phones. The android mobile phones has been equipped with an android device audio frequency counter which can directly display the value of the frequency of the sound of tambourines observed. By charging every area constantly, can be obtained the resonance frequency value of tambourine directly on the audio frequency counter column. average resonance frequency obtained from this research to tambourine successively from keplak, hadroh and bass is 750-1251 Hz, 681-1189 Hz, 630-1084 Hz, 503- 736 Hz, 270-448 Hz, 227,5-382 Hz, 146-332 Hz, 145-283 Hz. Keywords: Acoustic, tambourine.
