Abstract

Bending and rolling service providers in Subang Regency are still minimal, based on observation data in five workshops, there is only one workshop that provides bending and rolling services, in addition, in the manufacture of the bending roll machine, it is necessary to have an electrical installation as the power that drives the drive system and analysis of the calculation of the drive system as planning to determine and install the drive system to be used. This final project is a qualitative descriptive study with the stage of data collection, wiring diagrams and calculations, installation, testing, and analysis.  The results of the study can be concluded that: (1) the electrical installation uses two main components including a 1 phase 1.5 HP electric motor and a 15 A cam starter 3, (2) the analysis of the calculation of the drive system includes the calculation of the power of the motor drive with the results: driving torque = 269 , 66 Nm, Driven torque = 210.66 Nm, calculation of the final rotation ratio of the roller with the results: the final rotation ratio n3 = 39.94 rpm, chain calculation ratio with chain speed results: v = 0.15 m / s, the amount of chain workload = 88 kg, comparison of theoretical calculations with technical calculations (measured tests) which include electric motors: (1400 rpm): (1403 rpm) difference = 3 rpm, speed reducer = (46.6 rpm): (59.93 rpm) difference = 13.33 rpm, main shaft sprocket = (39.94 rpm):(32, 83) difference = 7.11 rpm.

Abstract

This study aims to schedule and implementation preventive maintenance on fruit fly catching tools with a solar powered Arduino system. Maintenance of these tools is expected to be able to help chili farmers in eradicating fruit fly pests that can cause crop failure for chili farmers. The stages carried out by the research team in the process of making and implementing a maintenance schedule for fruit fly traps. This research is a type of development research. Making a preventive maintenance schedule starts with making observations, then grouping components, making schedules, expert validation and implementation. The data obtained from the observations were analysed qualitatively descriptively. The results showed that: (1) Making a maintenance schedule for fruit fly traps starting from observation, component identification, initial planning, validation and implementation of the maintenance schedule; (2) The implementation of a preventive schedule with inspection and small repair methods is carried out on the main frame and electrical system; (3) Implementation of Inspection on frame manufacturing with a total of 100' Minutes and Small Repair with a total of 80; minutes during a four-month machine maintenance schedule. Meanwhile, the implementation of Inspection on the electrical system with a total of 240 minutes.

Abstract

Plastic waste remains a significant unresolved issue due to extensive usage and lack of public awareness. It continues to be a problem in both rural and urban areas. The difficulty in eradicating plastic waste means that it will continue to accumulate if not addressed seriously. This study aims to develop equipment for processing plastic waste, including the main frame, component holder, heating tube, and screw extruder. This type of research falls under research and development (R&D) and involves the following steps: identifying potential and problems, gathering information, product design, design validation, and design improvement. The study findings are as follows: 1) The main frame is constructed using black hollow iron 30x30x1.6 mm; 2) Design drawings for the main frame, tube holder, heating tube, and screw extruder in both 2D and 3D formats are provided. These drawings include dimensions and work symbols in accordance with drawing rules; 3) The Von Mises Stress test on the main frame, conducted with a 100 kg load, indicates that the highest tension is located above the end of the middle support, with a value of 73.09 MPa. This value is far from the melting point. The part with the lowest stress is the lower frame, with a value of 0.02 MPa; and 4) The Von Mises Stress test on the tube holder, conducted with a 50 kg load, shows that the highest stress is at the bottom, with a value of 1.813 MPa. This value is far from the melting point. The part with the lowest stress is the lower seat of the side, with a value of 0.001 MPa.
