Abstract

Waste is an environmental problem that is increasing along with population growth and public consumption. To solve this problem, an automatic device that controls the opening and closing of the trash can without direct touch is developed using an Arduino Nano microcontroller, HC-SR04 ultrasonic sensor, VL53L0X LIDAR, and MG996R servo motor. This research aims to evaluate the responsiveness of the sensor in detecting objects, the effect of the interaction of distance, angle, and object thickness on the sensor response time and aims to determine the effect of garbage volume on the response time of the indicator LED light. The test was conducted using the experimental method of distance variation of 20 cm, 30 cm, 40 cm, and 50 cm; angle variation of 0°, 10°, and 20°; and thickness variation of 10 mm, 65 mm, and 120 mm. Data analysis using multiple linear regression research methods shows a P-Value of 0.409 for the ultrasonic sensor with ɑ of 0.05, if the P-Value > ɑ, then H0 is accepted and H1 is rejected which mean that there is no significant effect of the interaction between distance, angle, and thickness of the object on the response time of the trash can lid opening sensor.

Abstract

Plastic waste, particularly High-Density Polyethylene (HDPE), poses a serious threat to the environment due to its extremely long decomposition time. One effective recycling method is the extrusion process, in which process parameters such as nozzle diameter and heating temperature significantly affect the production rate and the quality of the resulting filament. This study aims to analyze the effect of nozzle diameter and heating temperature on the production rate and diameter uniformity of recycled HDPE plastic filament. The method used is an experimental approach with a quantitative design, utilizing a single-screw type extruder machine. The tested parameter variations include two nozzle diameters (1.75 mm and 2.85 mm) and three temperature levels (200°C, 240°C, and 280°C). The results of the analysis, using factorial ANOVA and control charts, show that both parameters significantly influence production performance. The highest production rate, approximately ±1.0 kg/hour, was achieved with the 2.85 mm nozzle and 280°C temperature combination, while the combination of the 1.75 mm nozzle and 200°C temperature produced the most consistent filament diameter and the best quality, with a resulting diameter of 2.84 mm, which is very close to the target of 2.85 mm. Higher temperatures increase flow rate due to decreased viscosity, but also carry the risk of thermal degradation. This study provides practical guidelines for optimizing the HDPE recycling process through extrusion.

Abstract

Finding the appropriate thickness for the trash can. Will use the 3d printer method to make specimens and carried out by experimental methods that require several specimens to be tensile tested and the planned result is to find a strong thickness by knowing what thickness and layer will be used next. This research was conducted at the workshop of the Polytechnic of the State of Malang, there needs to be an innovation where the author makes several experiments  with  a  thickness  of  3  mm,  4  mm  and  the  last  one  is  5  mm  with  a  layer combination of 0.1 mm, 0. 2 mm and 0.3 mm to find out at what thickness and using what layer we should use, When we have found the thickness and what layer we should use we can make another trash can using 3d printing, and in using 3d printing parameters we must use 100% infill, From the results of data analysis using statistical software shows that the p-value is 0.000 with α of 0.05 which means the p-value ˂ α, then H0 is rejected and H1 is accepted.
