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

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

As one of the main fillers in concrete and asphalt mixtures, aggregate must comply with the required material standards. Aggregate sieve analysis is one of the tests that must be carried outbefore making a concrete Job Mix Formula (JMF). Aggregate sieve analysis testing is an important step to determine the size of the aggregate particle used in concrete mixtures and asphalt mixtures. Aggregate sieve analysis testing aims to analyze the aggregate grain size distribution, determine the maximum grain size of the aggregate used, ensure its conformity with technical specification standards and evaluate its impact on the quality and performance of construction materials. In this study, the combined percentage or percentage of coarse aggregate and fine aggregate was determined using analytical methods. This method involves using a series of sieves specific sizes to separate and measure the proportion of particles from the aggregate to be tested. Previous research shows that the distribution of aggregate gradations effect the stability, strength and durability of construction materials. The aggregate used as a test sample came from the Batang Kuranji river. The coarse aggregate used is 2000 grams in surface dry condition (SSD) and 1000 grams for fine aggregate. Dry surface condition on the aggregate were obtained after the aggregate was dried in an oven for 24 hours. The maximum aggregate size used for this test is 40 mm. Finenes Modulus (FM) of the material used as a test sample has accordance the required material fineness value. The results of the sieve analysis test provide a recommendation for a combined percentage of coarse aggregate of 64.8% and fine aggregate of 35.2%. Besides that, from the aggregate sive analysis test, it is known that the FM values obtained were 7.22 for coarse aggregate and 3.09 fine aggregate in the Batang Kuranji river.

Abstract

 Padang State Polytechnic (PNP), one of the first 17 polytechnics in Indonesia, is committed to creating a comfortable academic environment with adequate facilities and harmonious interaction between lecturers, staff, and students. Collaboration with many companies has increased the number of students and study programs admitted each year. However, the construction of facilities and infrastructure has reduced green open space by 26.88%. The construction of Buildings AB and E in 2012 has impacted the comfort and health of Building F users, obstructing air circulation and natural lighting, and increasing the demand for water and waste management. Recommendations are needed to convert Building F into a green building according to the Minister of Public Works and Housing Regulation No. 21 of 2021 to optimize natural resources, reduce environmental impact, and enhance comfort. This research aims to develop retrofit recommendations, including replacing window openings, adding green areas, planning natural lighting, and improving waste and wastewater management systems. Data was collected through literature review, observation, quantitative methods, interviews, and documentation. The initial assessment of Building F scored 21.81% according to the Checklist for Existing Buildings in the Green Building Performance Assessment, indicating a significant need for improvement. The implementation of the recommendations will potentially increase Building F's score to 70.30%, placing it in the "MADYA" category, reflecting better sustainability and efficiency standards.. This demonstrates the success of the recommendations provided and the potential to improve building performance in the future
