Abstract

This research introduces the design of a multifunctional animal feed chopper machine using a gasoline engine as the driving system. The gasoline engine used is Ecolite TE160 5.5 HP which can provide reliable power and performance to drive the feed chopper machine. The test material used is banana stems which are effectively finely chopper to obtain consistent and high quality chopper results. This design methodology includes identification of needs, mechanical design, material selection and testing of the tool. The working method of this machine is to insert the banana stem into the input hopper where the chopper knife rotates using a gasoline engine as the driving source. The chopper blade is specially designed with sharpness and thickness that suits the needs needed to get maximum and effective chopper results. The frame of this multifunctional animal feed chopper machine uses L 35 mm x 35 mm x 2.5 mm profile steel with a size of 105 cm long x 35.5 cm wide x 72.5 cm high. From the data obtained, the engine rotation used is 2500 Rpm. The results of testing this machine can be concluded that the heavier the material to be chopper, the longer the chopper time obtained, the thickness obtained is consistently 1.3 cm thick. Overall the development of a multifunctional animal feed chopper machine represents a significant advancement in pemp technology

Abstract

Furthermore, in the development of this potato peeling machine, human resources play a crucial role. The This study presents the development of a potato peeling machine focusing on structural reliability and efficiency. Human resources play a crucial role in this development. The machine uses L-shaped iron profiles and stainless steel plates, aligning with sustainable and recyclable materials for environmental compatibility.An analysis of the machine's shaft, made of AISI 1045 steel with a 20 mm diameter, shows high structural reliability for efficient potato peeling. The machine is designed with a 5 kg capacity, integrating 30x30x3 mm L-shaped iron profiles and stainless steel plates. Powered by a 1/4 HP electric motor, the machine measures 500 x 500 x 892 mm, including a peeling cylinder of 35 cm diameter and 34 cm height, with shaft support from P204 bearings.Frame structure analysis under a total load of 50 kg reveals maximum and minimum stress values of 69.44 MPa and 2.055e-11 MPa, both below the ASTM A36 steel yield strength limit of 250 MPa. Maximum and minimum displacements are 0.39076 mm and 1.00e-30 mm. Safety factor analysis yields maximum and minimum values of 1.217e+13 and 3.575, exceeding the recommended range for static loads. In conclusion, the heavy-duty machine frame is safe and suitable for the proposed design, ensuring safety and optimal performance. The machine combines structural reliability with operational efficiency, ideal for peeling potatoes. The use of high-quality materials and detailed structural analysis ensures durability and performance, setting a new benchmark for agricultural equipment.

Abstract

Technological developments are currently increasingly rapid and the impact of these developments is that various kinds of design technologies will emerge, especially in the fields of mechanical engineering and automotive methods. Therefore, a lot of research and analysis is needed, one of which is the braking load on the drum braking test equipment through brake pressure parameters using a GX 160 robot type machine. The aim of this research is to determine variations in the braking test equipment on load. The method in this research is data collection through literature study, observation and experimentation. The type of tool in this research is a drum braking test tool. In this study the load was varied from 0 gr to 1300 gr. The research results showed that torque level values ranged from 1,225 Nm to 6.37 Nm, power values ranged from 21,142 Watts to 652,725 Watts, and different rpm rotations due to additional load would reduce the rotation (rpm) ranging from 1663 to 979 rpm, and It was obtained that Pertamax fuel consumption levels ranged from 0.157 ml/s to 0.862 ml/s and Pertalite fuel consumption ranged from 0.157 ml/s to 0.961 ml/s.

Abstract

The increasing amount of plastic waste is one of the main challenges in current waste management. One solution that can be implemented is processing plastic waste into value-added products, such as paving blocks. This study aims to design and develop an efficient melting machine for processing plastic waste into paving blocks. The methods used in this research include the design phase using Solidworks 2022, prototyping, and testing of the melting machine. During the design phase, an analysis of the melting machine requirements was conducted, including capacity, operating temperature, and safety aspects. The design of the melting machine was carried out by considering ergonomic aspects, energy efficiency, and the ability to produce high-quality paving blocks. This process involved the use of materials resistant to high temperatures and thermal insulation materials to maintain optimal operating temperatures. The melting machine was then tested under various operational conditions to evaluate its performance. The melting machine must reach the required operating temperature of 200°C to melt plastic waste without damage. PET (polyethylene terephthalate) plastic waste processed into paving blocks has a compressive strength of 11.09 MPa and meets Class D quality standards in accordance with SNI 03-0691-1996

Abstract

This research discusses the analysis of the rotary system sand sieving machine frame with a capacity of 10 kg using Solidworks 2018 with the Finite Element Analysis (FEA) Method. This research aims to overcome manual problems in the sand sieving process in building construction by developing an efficient and reliable automatic machine. Technology is identified as a basic need of modern society because of its ability to increase efficiency and productivity in various activities. Sand, as an important construction material, must be sieved from rocks and gravel before use. Current manual sieving processes require a lot of effort and time, prompting the need for automated solutions such as the rotary sand sieving machine designed in this research. Machine design focuses on frame strength as the main component that supports operational loads. The frame strength analysis was carried out using Solidworks 2018 with the FEA method to ensure its safety and resistance to a load of 10 kg. The analysis results show that the machine frame can bear operational loads well. The maximum stress that occurs in the frame is 9.248 N/m2, far below the yield strength of the material used. The maximum deformation (displacement) that occurred was 1,058 mm, mainly concentrated in the critical areas analyzed. Safety factor analysis shows that the frame meets safety standards with a safety factor of 2.7, exceeding the expected value for construction industry applications
