Abstract

In this paper, an automatic pet feeding machine is built using the 3D Printer machine and an opened source control system to help people with busy activities to be able to feed their pets on time. The machine is built using 3D Printer machine. The control system is built using the NodeMCU ESP8266 platform module and ultrasonic sensors. The controlling device uses a smartphone that is installed blynk application software that has the principle of the Internet of Things. The machine works by opening it’s valve to control the water’s discharge, a servo motor to open the feed container, as well as a timer to regulate the time of feeding. The valve can be set in 4 conditions. There are 10 degrees, 20 degrees, 30 degrees and up to 40 degrees. Then for the feed distance’s display it will provide information about the distance of the feed to the sensor, for a maximum distance of 9 cm in accordance with the distance sensor attached to the roof of the feed container with the sensor attached to the bottom of it. This machine can work continuously and automatically as long as there is an electricity source in the house and the owner holds the control of the blynk application software on their phone.

Abstract

The cleaning process plays an important role in producing hygienic porang tubers, so that later chips and porang flour have good quality. Currently, the home industry for processing porang tubers still uses a simple method, namely using a manual washing machine so that it requires a lot of energy and a long time. One alternative to increase efficiency and productivity is to make a porang tuber washing machine. In planning this machine, it begins with field studies and literature. Planning in designing this machine includes planning for motor power, shaft, bearing, pulley-belt, sprocket-chain and budget design, after calculating and getting results it is necessary to conduct experiments to get conclusions from this machine. In planning the calculation of the machine, it requires a motor power of 2.2 HP with a motor rotation of 1400 rpm and a shaft rotation of 35 rpm, a force of 25.6 N, a torque of 1.920 N.mm, the selling price of the tool is Rp. 15,970,000 and the payback period is achieved in 228.4 days or 28.5 weeks or 7.1 months

Abstract

Light fishing techniques are widely used to improve marine fish catches by adjusting the spectrum and intensity of light-emitting diodes (LEDs) to attract specific species. Grouper (Epinephelus spp.) are known to respond well to red light, although the optimal light intensity remains unclear. This study proposes a dual system consisting of a pulse-width modulation (PWM)-based red LED brightness controller and an artificial intelligence (AI) fish detection module using the YOLOv4 algorithm. LED brightness was varied at duty cycles of 50, 100, 150, 200, and 250 (1 kHz), producing luminous flux values between 120 and 650 lm. Field experiments conducted at the Pamekasan coast using 10 grouper samples showed that 80% of fish aggregated at a duty cycle of 150 (~420 lm at 1.5 m). ANOVA results (p0.05) indicated significant differences among light intensities, with the highest attraction observed at this level. These findings suggest the existence of an optimal light intensity threshold. Further studies with larger samples and multi-site experiments are required to validate these results and evaluate ecological impacts.
