Abstract

The distribution is an activity that is often carried out in various places, such as in schools, fairs, colleges, and other places. To attract the attention of visitors to want to take a proportion of the visitors reluctantly took a brochure distributed, because the distribution is less attractive, giving flyers with poor grammar, and disrespectful. In this study generated humanoid robot divider brochure with attractive looks, then the presence of this robot can help in the distribution process. This robot is equipped arm moves, sound, similar led eyes, and a mouth that serves to attract the attention of visitors to pick up a brochure distributed and process control using a microcontroller. The results of this study, the robotic arm can move, brochure paper can out one by one, and the robot can make a sound.

Abstract

Sensors that are able to identify the type of gas are needed in the industry. One of them is a Quartz Crystal Microbalance (QCM) sensor which can produce a constant resonance frequency. In this study, we intend to determine the sensitivity of the QCM gas sensors which are coated with different polymers. QCM gas Covered with polymer sensor based QCM aim to increase the sensors ability to absorb molecules on the surface of the QCM sensor. The sensor array coated with different polymer materials will produce different frequency response output patterns for each type of gas identified. The test results showed that the QCM sensor coated with OV 17 polymer material was more sensitive by producing sensitivity of 8.4 Hz /ml alcohol, 9.96 Hz /ml 2-propanol, 35.88 Hz /ml acetone, 39.64 Hz /ml benzene.

Abstract

The development of Hydroulic Regenerative Shock Absorber starts with presenting theories that work, and simulates them with numerical computing software to becompare with conventional shock absorber systems. The generation energy of the regenerative suspension system is only effective for high amplitude. When the amplitude is low, the generation energy will decrease as a result of bidirectional rotation and inertial losses. The greater the generator rotation, the higher current, and power generation. In the HMERSA fluid flow simulation 1 input and single output using the Fluid SIM software. the input given is 3 Hz on the hydraulic cylinder that is on the 4-wheel vehicle. The simulation was done by changing the hydraulic circuit and adding a check valve mechanism so that the rotation of the hydraulic motor becomes unidirectional. In this simulation there is no generator component because in the Fluidsim software does not provide these components in the simulation. The simulation using the Fluidsim software is intended to find out whether the hydraulic circuit that has been designed runs well marked by the rotation of the one-way hydraulic motor rotation. The design design of HMERSA with 1 input 1 output can run well marked from the rotation of the hydraulic motor into one direction when the conditions are expansion or compression. The torque value that occurs during an expansion condition is 1.1 Nm, while for the torque value that occurs when the compression condition is 1.6 Nm. The power generated from the hydraulic motor when the expansion condition is 1.6 Watt. Whereas when the compression condition of the power of the hydraulic motor that can be produced is 4 Watt.

Abstract

Everyone really needs air in the process of breathing, but they don't know how much ammonia (NH3) is in the air. Therefore it is necessary to monitor ammonia (NH3) levels in the room with an Internet of Think (IoT) based ammonia (NH3) concentration meter with Wemos D1 as a microcontroller and an MQ-137 sensor, with this measuring instrument you can find out the level of ammonia levels ( NH3) in the room in real time using the MQ-137 as an ammonia level sensor (NH3), a programmed Wemos D1 that can process the level of ammonia (NH3) levels in the air. From the experimental results that the MQ 137 sensor can be said to be linear because it gets the results of R2 = 0.9613216, the ammonia gas condition is more than 25 ppm, the buzzer and fan will turn on.

Abstract

Hydroponics is a way of farming that does not use soil as a planting medium, but its uses water that contains nutrients. In the growth of hydroponic plants, it can be affected by various factors, one of them is the delay in adding hydroponic water nutrients. This research aims to create a system monitoring nutrient levels and water availability in reservoir. Then, the microcontroller processes the data and sends the data with the help of NodeMcu ESP8266 to Firebase. The data in Firebase will be forwarded to Android using the MIT App Inventor software with Internet of Thing (IoT) technology. In this research, the hydroponic plants used are lettuce which has a nutritional value of around 560 - 840 in units of parts per million (ppm). As a result of testing, the sensor is not able to measure nutrient levels reaching 850 ppm and the xkc-y25 sensor can detect water in a full or reduced reservoir, all of these sensors data are measured in real time, and can be monitored via android.
