Abstract

The waste of empty palm fruit bunches (EFB) as compost material and as fiber material needs to go through a decomposition and chopping process to simplify the processing process. The empty palm fruit bunches (EFB) chopping machine has now been developed in various regions using various types of transmission, propulsion, and also various models. The design of chopping machines is also increasingly diverse in line with the increasing market demand for processed products from empty palm fruit bunches (EFB). Based on these conditions, an appropriate transmission system is needed to lighten the workload of the machine, increase production yields, and save production costs. From the results of the research, it was found that the empty palm fruit bunches chopping machine with a total capacity of 100 kg / hour was tested. The machine is driven by an electric motor with a power of 4 kW and a rotational speed of 1440 rpm, which is transmitted using a pulley and belt open drive transmission system. The power from the machine is transmitted to the cutting section to chop the empty palm fruit bunches well

Abstract

Soil conditions significantly impact plant growth. Liquid fertilizer is used to optimize plant growth, and soil moisture is crucial too. Insufficient moisture causes withering, while excess leads to reduced soil oxygen. To monitor soil moisture, researchers developed an IoT-based Smart Urban Farming device using ESP32 microcontroller and 6 soil moisture sensors. The system operates through CNC Milling with X and Z axes movement. ADC pin on ESP32 reads sensor values, controlled and monitored by thinger.io. The device can work automatically or manually. Input and output testing ensures performance assessment. Soil moisture sensor testing yields 2091-3998 bits range, stepper motor testing shows 1.96% highest error, and water pump testing takes 0.05 seconds/milliliter. Mustard plants use a 60% set point for soil moisture, and the pump activates at 55%. The device shows good performance with an error range of 0.03% - 0.08%, demonstrating the effectiveness of the smart urban farming system.
