Abstract: AUSTRIA, VINCE ANGELO C. and TATAD, LEMUEL G. Design and Development of Briquette Quality Checker. Undergraduate Design Project. Bachelor of Science in Electronics and Communication Engineering. Cavite State University, Indang, Cavite. December 2018. Adviser. Ms. Nemilyn A. Fadchar. The main objective of the project was to design and construct a briquette quality checker machine. Specifically, it aimed to: design and develop a quality checker control system; develop and fabricate quality checker control system of briquetting machine; develop software to control the system; test and evaluate the reliability and performance of the system through pilot testing; and conduct cost computation of the study. The design project was composed of four parts- the panel box, drying machine, tumbling test machine and drop test machine. The panel box composed of microcontroller which controls the test machine, motor drivers control the steps and angle of the gear and servo motor, power supply supplies 12VDC to the system, PCB board controls the fan and oven, voltage regulator regulates 5V power supply and LCD display to view temperature and time. The drying machine Composed of heater, a nickel-chromium wire, linear rail, and, thermocouple to regulate the optimum temperature at 1005±2 degrees centigrade, vent to release the moisture on the briquette and a load cell which measures the weight of the briquette until the briquette has 10 percent moisture content. The tumbling test machine composed of gear motor, metal sheets, steel bars, mild steel casing and screws and threads. And the drop test machine composed of beam sensor which checks whether the briquette is accept or failure, gear motor to rotate the sensor and brushes, and limit switch for safety control during idle. The project was tested and evaluated at the Engineering Science Building of the College of Engineering and Information Technology. Testing was done by putting 60 briquettes by six batch were gathered to record the performance the machine system using the designed and developed device/system and the established measurements. The other parameters (reliability) were evaluated by running a trial test. Based on the results of the evaluation, the system was said to be functional, usable, and reaches 93.33 percent accuracy in sensor weighting before drying and 95 percent in sensor weighting after. The tumbling time accuracy was 85 percent and the briquette that falls directly to the drop test was 95 percent. The drop test machine accuracy in determining whether the briquette is passing or failed was 93.33 percent. The reliability of the machine during trial test drying test was 92 percent, in the tumbling test was 83 percent and drop test was 86 percent. For the compressive strength test of the briquettes, we obtained results from OneLab in UPLB. The results show that the strength of the briquettes from the quality checker were better than the commercially available briquettes. For further improvement, the proponents recommended to have an exactly 2cm hole net to be used in the sieving machine, a round tube to be used fall test machine in case of cylindrical object, replacing a mechanical timer on the oven to reduce noise, and Use of different methods in assessing the quality of the briquettes. The total cost of the design project was PhP 42,340.75.
