Abstract

Ornamental fish enthusiasts sometimes busy with other matters that take a long time so they do not have time to care for their pet fish. Therefore it is needed automation in maintaining fish in the aquarium. This study aims to make it easier to maintain ornamental fish in the aquarium by automate feeding activities, replacing water, and adjusting water temperatures. This automation uses the prototype method so that it is easy to improve continuously, data collection is done by collecting several articles related to the title taken by the author. NodeMCU is used as a temperature sensor data reader, pH, Ultrasonic and servo data receiver, relay to turn on the valve, pump, heater, fan. The results of the data will be sent wirelessly to smartphones via the Blynk application. The results of this study are a tool that can feed according to a predetermined schedule, replacing water according to the acidity of the water's pH, and adjusting the temperature to its natural habitat. Thus this automation tool will be useful for fans who are busy with their work, especially those who often go out of town in days.

Abstract

The development of medical equipment with advanced technology can provide convenience in providing services to the community. One of the equipment that is in the hospital and most often used is an IV. In its use, manual infusion is used to determine the volume of the infusion and must be monitored every hour or even minute by the nurse. This is considered quite difficult, especially in the era of the Covid-19 pandemic where minimal interaction is required from 2 individuals. This is done by utilizing sensor technology to monitor the patient's condition so that the frequency of the nurses checking the condition of the infusion is getting less. Therefore, in this research, manufactured of an infusion monitoring system using aweight sensor (Load Cell) based on the ATMEGA 328 microcontroller was carried out. The sensor of this monitoring system uses a Load Cell Weight Sensor with the HX711 module which is integrated into the ARDUINO UNO MCU. The output of the system is displayed on a 16 x 2 mm LCD as well as a Macro Excel which will display the percentage value of intravenous fluids in the PC and real-time automatic data logging into the macro excel. The infusion used uses Nacl fluid infusion. The test results of the system as a whole show that the data for measuring levels (%) of intravenous fluids can be sent and displayed on the LCD and PC. The incoming data is converted into a table at certain time intervals according to the user's choice into the operator. The experiment was carried out 10 times by looking at changes in the contents of the infusion fluid over time in 11 stages where the LED lights up when the weight of the infusion reaches 40 - 46 grams. Then, the buzzer and LED have turned on when the weight of the infusion is less than 5 grams. From the experiment, it can be concluded the 10% setpoint alarm works well, i.e. when the infusion load is less than the 1% set point, the buzzer and LED will light up until the intravenous fluid is replaced with a new one.

Abstract

Extracting the information from an online job advertisement might be a little tricky. The information is wrapped with redundant information, called boilerplate, that is not related to the job at all. The information also needs to be segmented and classified into the right class or groups. After the information has been classified, it is easier to find the features (e.g., required skills and required education) that make the later processing faster.

Abstract

Natural fibers have the ability to reinforce polymeric materials. In this work, sugar palm fibers were added as a reinforcement agent to a polypropylene (PP) matrix to form biocomposites. Flexural strength measurement in accordance with ASTM D790-17 was carried out on PP composites with the sugar palm fiber content changed from 0 to 30 wt.% in 5 wt.% steps. The flexural strength data show a composition dependence on the fiber content with a maxima (52.09 MPa) obtained in 15 wt.% fibers. Sugarcane bagasse-PP composite together with wood board composite and neat PP as existing materials by automotive industry were used as reference material in the study. This sugar palm fiber-PP composites offer lower density in comparison with wood board composites and PP. The area density of the composites is in the range of 1285-1635 g/m2 for the composition studied while PP and wood board have area density of 1466 and 1700 g/m2 respectively.
