Abstract

Body flexibility is one of the factors that greatly helps physical health because it can help in prevention, help restore muscle, and improve efficiency in various physical activities. One method to measure the body speed level is Sit and Reach Test using the Sit and Reach Box Scale measurement tool. Technically, this measuring instrument is still manual, simple and its production is still very limited. Therefore we need a measuring device to use electronic components to help process better and better in terms of which can be adjusted to good or bad by using the parameter norm Sit and Reach Test. The purpose of this study is to design a flexibility measuring instrument using a microcontroller based proximity sensor. This tool works with the arduino unu microcontroller as the main controller, HC-SR04 ultrasonic sensor as a distance reader for body flexibility, LED indicators and speakers as a sign of body flexibility, then LCD and delphi 7 applications using serial communication as a display of body flexibility.

Abstract

Palu is municipality located in equator where solar radiation is abundantly available. therefore, utilization of solar energy is potential. solar energy technology has some advantages, such as are of renewable energy, having no pollution an d available everywhere. recently, the use of solar energy technology, especially photovoltaic, has been used widely such as battery charger using photovoltaic. charging battery with photovoltaic as source, has been limited by instability of photovoltaic output voltage. so voltage input of battery is also fluctuated. This research applies cuk converter to increase and decrease the voltage from photovoltaic. to stabilize the output of cuk converter at 13,8 V. PID control is applied with Kp,Kd,Ki, and setpoint are 0.5, 0.25, 0.02, and 110 respectively. The result shows that use of cuk converter can raise and decrease the source voltage by regulating duty cycle, as well reduce ripple of photovoltaic voltage. the average efficiency of the cuk converter is 79 % when charge the battery. the duration time needed to charge fully the battery is 2-4 hours.

Abstract

The need for fish is increasing every year. Because it is increasing every year, fish farming must be increased in line with the use of improved fish farming technology. So that it requires an adequate technological structure and mechanization. Based on this background, the arduino-based floating robot for feeding freshwater pond fish is designed to be able to apply technology that is useful in feeding farmed fish. The arduino based floating robot fish feeding freshwater fish pond using Arduino Mega 2560 as its microcontroller, 4 Sharp 2Y0A21 sensors that function to detect pond walls, RTC functions as a timer so that it can feed fish according to the time set on the tool, LCD functions as the information viewer of the tool, the L298N motor driver controls the DC motor and the servo motor functions as the opening or closing of the food valve on the appliance. In the test, the arduino based floating robot fish feeding freshwater fish pond is able to float in water and can feed fish based on the time available on the tool. The Sharp 2Y0A21 sensor as a pool wall detector has a distance reading in the range of 1 millimeter to 10 centimeter. The robot can avoid the pool wall with a span of 3 - 7 seconds, this is influenced, among others, by surging water, wind, sensor response, and DC motors.

Abstract

The PDAM is still using an analog flow meter. For PDAM customers, information on analog flow meters is difficult to access and convert into payment amounts. With an analog reading system, the PDAM officer still records using the manual method of the customer's total water consumption data. From the problems above, we need a digital reading system that can display customer water consumption and payment data that can be accessed by customers. The reading of the volume of water consumed by PDAM customers via SMS is a device designed based on the Arduino Uno microcontroller, equipped with the ability to monitor water usage in real time using SMS media. The reading of the volume of water consumed by PDAM customers uses a water flow sensor that functions to read the flow of water that passes and provides pulse output. Arduino Uno receives pulse output from the water flow sensor which is then converted into a number that shows the number and tariff of water usage of PDAM customers. The LCD displays information on total usage, usage rates, time and date in real time. The SIM800L module sends SMS based on orders received from customers and PDAM officials. The results achieved in this study are the water flow sensor is able to read the amount of water consumption of PDAM customers with an average deviation of 0.034%. Tests show the results of payment conversions are in accordance with the PDAM payment model in Palu City.

Abstract

Utilization of synchronous generators on micro-hydro Power plant (PLTMH) need direct monitoring with some parameters such as voltage and current. From the results of the monitoring, the information can be obtained whether the synchronous generator installation is appropriate and produce the expected output power. In some studies, the results of current and voltage measurements are still done by manual use of multimeter, so that the data obtained can not be recorded continuously. The purpose of this research is to create a monitoring system on synchronous generators using arduino-based data logger. Monitoring system using data logger is equipped with timing system. Based on the research that has been done can be concluded that the monitoring system on synchronous generators using arduino-based data logger can record current, voltage, and power in real time resulting from generator performance and then record or save the data into the form of CSV file (comma separated values) every 2 seconds into the micro SD and the data can be displayed through Microsoft Office software namely Microsoft Excel.

Abstract

In rural areas, free-range chickens are raised naturally, that is, the eggs are incubated by their parents directly so that the breeding of chickens is not optimal, because the native hens are only able to incubate a few eggs. Therefore an automatic chicken egg incubator is needed. Egg incubators that use automatic controllers in order to facilitate the hatching process, get maximum hatching results as expected and be able to find hatching information remotely by sending information via sms gateway. The hatching temperature is 37-380C and turning the eggs every 8 hours, starting from the eggs being put in the incubator until the eggs hatch. The data from the sensors will be processed in the diarduino and sent to the hatchery owner via SIM800L V.2 when the sound sensor detects the sound of the hatched egg. The information about the eggs that have been hatched comes from the sound sensor, even though the farmer is not in the hatchery. Experiments were carried out using 20 chicken eggs as a sample. The results of the successful hatching test were 4 chickens with a 20% success percentage, due to a power cut during the hatching process.
