Abstract

In order to achieve an energy-efficient vehicle, many aspects had to be considered, including the weight of the vehicle's body. The weight of the vehicle's body depends on its design and materials. As part of the energy-efficient initiatives, the design of the energy-efficient car developed by a Mechanical Engineering Team of Universitas Andalas needs to be redefined to improve its performance due to its active participation in national competition. Autodesk Inventor software's capability supported a reverse engineering strategy to enhance the car body design. Meanwhile, the appropriate car body material was selected using the Analytic Hierarchy Process (AHP). Furthermore, the improved car body design was evaluated using an academic version of ANSYS R1 and Fluent software. A weight reduction of 8 Kg is gained due to improving the new car body design and with the achievable thickness of 3.4 mm. Accordingly, it could minimize the Coefficient Drag (CD) of the new car body design to 0.066275. This result indicates a further improvement of the new energy-efficient car body design that would accelerate the car's performance and gain better results in the next national energy-efficient vehicle competition.

Abstract

A paradigm shift in waste management needs to be carried out in a sustainable manner. Education regarding residents' awareness and skills in applying the principles of reduce, reuse, recycle, and replant (4R) is very important to deal with waste problems from the source. Waste banks that involve women's participation serve as social capital in community-based management. In Nagari Pungguang Kasiak, Padang Pariaman Regency, Indonesia, a waste bank is implemented by integrating the 4R principles through the collection and sorting of dry waste, managed with a banking-like system, where what is saved is waste, not money. Community empowerment is carried out through counseling, education, and training with emancipatory participation methods, as well as interactive dialog within the community. In addition, building partnerships and cooperation mechanisms between waste bank managers and stakeholders is very important. The Sehati Waste Bank in Nagari Pungguang Kasiak has provided tangible benefits to the community, such as reducing waste volume, improving environmental cleanliness, and increasing economic independence. The economic benefits obtained from waste savings also contribute to electricity payments and food purchases. This program plays a role in creating a cleaner, greener, and healthier environment. With integrated waste management, community creativity and innovation can be encouraged, thereby improving the overall welfare of residents.

Abstract

The advantage of biolubricant compared to mineral oil is that biolubricant can ensure environmental sustainability. This research aims to investigate sustainable biolubricants of virgin coconut oil (VCO) and olive oil on wear behaviours with different fatty acid compositions and surface roughnesses in the mixed lubrication regimes. Tests were carried out on pin-on-disc equipment at a speed of 500 rpm with loads of 50 and 100 N. We used two types of biolubricants and surface roughness of the disks (0.8 and 6.3 µm). The research results show that the lauric acid content in VCO could reduce the wear rate of the disk. The surface roughness of the disc had a significant influence on the wear rate for both biolubricants; the smoother the surface of the disc, the more wear rate will decrease. The effect of surface roughness of the disc with both biolubricants could reduce the scar width of the disc and the scar diameter of the pin. The scar width of the disk was higher when compared to the scar diameter of the pin; by using VCO, there was a decrease of percentage in scar width of 32% by using smooth surface. VCO could be a promising sustainable bio-based lubricant in the future, especially in the mixed lubrication regimes

Abstract

This community service activity aims to increase the awareness and skills of Empowerment Family Welfare (PKK) members in managing inorganic waste, encouraging household economic independence through a waste bank-based savings system. The program was implemented at the Pungguang Kasiak Village Office, Lubuk Alung District, Padang Pariaman Regency. A participatory and educational approach was used in this activity, consisting of socialization regarding the importance of waste management, technical training in waste sorting, weighing and assessing waste with economic value, and forming structured working groups under the coordination of the PKK. The activity also includes monitoring and evaluating the effectiveness and impact of improving the family economy. The activity results show that this approach can empower PKK members as agents of environmental change and drive forces for the family economy through sustainable household waste management.

Abstract

Wear of razor blades often occurs when a man shaves his facial. In this paper, the observation of wear characteristic with different types of material and lubricant is investigated. The experiment was conducted on 6 students of the Mechanical Engineering study program with uniform beards and mustaches for 6 weeks. Each week, the wear from the surface of each blade was observed using an optical microscope. Two types of razors were investigared with different materials based on the price, which are consisted of cheap razor (type-A) and expensive razor (type-B), each of which has 3 blades. There were three types of lubricants used, namely: water, liquid soap, and foam. The result shows that type-B razor is better than type-B razor because the material has a high carbon content based on chemical content from testing with Energy Dispersive X-Ray (EDX). Foam lubricant can slow down the wear on razor blades. The 1st blade razor wears out faster than the 2nd and 3rd bladem, respectively.
