Abstract

The function of the frame on the electric motorcycle is to support the rider's load and where several motor components are combined, and also acts as the basic form of the motorcycle itself. The design of the electric motorcycle frame design also needs a finite element analysis. The analysis computes and produces formulas to estimate the actions that can be performed on the object, where this method involves dividing the structure into smaller elements connected by nodes or in other words, the discretization of elements. The objective of this research is to analyze the yield strength level of the electric motorcycle frame design under static loading conditions in accordance with the load safety standards of two-wheeled vehicles in Indonesia. The subject of this research is an electric motorcycle frame design with a naked bike frame type. The material used in the frame is aluminum alloy 6061 T6. The total loading during simulation is 265 kg. The quality of element discretization obtained in the electric motorcycle frame design is 0,278 with the size of each element of 5,5 mm. The maximum von Misses stress obtained is 125,3 MPa with a maximum deformation of 0,08618 mm and the safety factor is 2,154. The results of this study provide a statement that the electric motor frame design is able to withstand the load during simulation.

Abstract

Excavators are multi-purpose equipment that has various functions. To keep the excavator in top condition even though it’s used continuously, it’s necessary to carry out preventive maintenance on the excavator unit. Preventive maintenance is maintenance carried out on a unit to prevent unexpected damage and to find conditions that could cause damage when using the unit. The reality in the field is that there are many delays in implementing preventive maintenance on excavator. Delays that occur will have an impact on the excavator both in terms of unit condition and unit productivity. This study aims to analyze the effect of preventive maintenance on excavator units in the period February to June 2023 using the Physical Availability, Mechanical Availability, and Effective Utility calculation methods, as the potential lost costs that the company will incur if there is a delay in preventive maintenance on the excavator unit. The analysis results show that units with timely preventive maintenance have a higher average value of 28% for PA, 31.7% for MA, and 24.8% for EU. Delays in preventive maintenance affect the condition of the unit, where the lifetime of a component should be used longer. The estimated losses experienced by the company were estimated at IDR 433,700,000 per unit during the data collection period, from the total units that experienced delays in preventive maintenance.

Abstract

Banana leaf is a part of the banana that is rarely utilized and even used as waste by the Indonesian people. Inside the banana leaf there are fibers that can be used as a hybrid composite reinforcement material. The choice of glass fiber is because it has good strength value, light weight, and low price. This study has a goal to determine the effect of volume fraction on the tensile strength of hybrid composites of banana leaf fibers and epoxy-matrixed glass fibers. The fibers were soaked in 5% NaOH water. The volume fractions used were 40%, 50%, and 70% fiber. The specimen size standard used is ASTM D638-14 and the composite manufacturing method uses the Hand lay-up method. After conducting the tensile testing process, it was found that the 70% volume fraction had the highest tensile strength value with a stress value of 80.2 MPa and a strain value of 0.07%.

Abstract

Clutch discs in motor vehicles are commonly made from asbestos, a material that is hazardous and environmentally unfriendly. Therefore, there is a need for more eco-friendly alternatives by utilizing waste materials, such as glass waste and natural fibers. This study aims to evaluate the use of resin-based composites reinforced with natural fibers and glass waste as alternative materials for clutch discs. We tested various combinations of resin, natural fibers (coconut fiber, coir fiber), and glass powder to determine which composite offers the best hardness properties. Samples were divided into two groups with different compositions and tested for hardness using the Rockwell method. The results showed that the composite with a composition of 20% glass waste powder, 20% coir fiber, 20% glass powder, and 40% resin achieved the highest hardness, with a Rockwell hardness value of 70 HRB, which closely approaches the standard hardness for automatic transmission clutch discs.This research reveals the significant potential of using natural fibers and glass waste as sustainable and high-performance composite materials. The findings contribute to the development of green composite materials and offer a more environmentally friendly alternative in the automotive industry.

Abstract

Increasing fuel consumption efficiency and controlling fuel price increases and environmental impacts challenge manufacturers to think outside conventional vehicle systems by focusing on aerodynamic drag. Various efforts can be made to reduce aerodynamic drag, one of which is by delaying flow separation. Separation delay can be done by providing passive control treatment in the form of dimple and spoiler and active control in the form of blowing. This study aims to analyze aerodynamic drag by applying dimple, spoiler, and blowing to the upper side of the rear of the vehicle model using a computational method. Computational tests are carried out at an upstream speed of U0 = 20 m / s. Flow pattern analysis is presented to support the results of the drag coefficient (Cd) obtained. The results of the analysis show that the application of dimple, spoiler, and blowing to the upper side of the rear of the model successfully delays separation and reduces backflow and reduces the amount of drag (Cd).

Abstract

Given Indonesia's growing population and economic development, the country is experiencing a greater need for fuel. There are now a number of alternative fuels available to lessen the ongoing need on fuel oil. One of the most affordable, cleaner, and readily available fuels worldwide is liquefied petroleum gas, or LPG. The geometric design of the burner, the flow dynamics contained in the non-premix flame flow structure and its function to stabilize the combustion process play an important role in the mixing process between fuel and air. The purpose of this research is to ascertain how nozzle thread changes affect the flame characteristics of burning LPG (liquified petroleum gas) fuel. In order to create an effective and efficient burner design, thread variations can be used to establish the properties of the diffusion combustion flame, such as flame stability and combustion temperature. Data collecting findings indicate that nozzles with threads have a greater temperature value than nozzles without threads. The proportion of.

Abstract

Efforts to find new energy sources continue, including Renewable Energy Sources (RES). Biomass is an alternative source of renewable energy and one example of biomass is briquettes. Briquettes are solid fuels made from renewable organic materials derived from plants such as mangrove wood, coconut shells, and palm kernel shells. Thus, briquettes can serve as an alternative energy source to replace fossil fuels like coal. In this study, briquettes were produced using a briquette pressing machine with a screw conveyor method. The briquette materials used were palm kernel shell charcoal dan mangrove wood charcoal, with variations in funnel angles to observe the impact on briquette quality. The funnel angles tested were 55̊, 60̊ and 70̊. Three tests were conducted : density, hardness and Water Boiling Test (WBT),with five data points for each test. The best results were obtained for mangrove wood briquettes at a 55̊ funnel angle, with an average density of 1,12 grams/cm3, average hardness of 38,34 kg/cm2 and average WBT value of 5.785,02 kJ/kg. Funnel angle significantly influenced the quality of the produced briquette.

Abstract

The design of this briquette dough mixer machine is designed to mix briquette dough with a horizontal stirrer, the mixing knife used is a helix with two blades with different directions and sizes. This mixing machine uses a 1 HP AC motor with a motor speed of 1,400 Rpm, the engine also uses a 1:20 ratio gearbox, the rotation is obtained at 70 Rpm then reduced again to 50 Rpm using the pulley ratio so that the rotational speed achieved is 50 Rpm. The capacity of the mixing tube made is 10 kg in one mixing process, to be able to reach a capacity of 10 Kg requires matching the composition of the dough which consists of 5.75 Kg of charcoal, 0.287 Kg starch and 4.025 Kg water. In the process of mixing the dough, the starch is first dissolved in hot water, then slowly poured into the drum which has been filled with charcoal powder. Data collection was carried out by comparing 3 time variations, namely 10, 20 and 30 minutes. After mixing, the dough from each time variation was divided into 4 samples weighing 2.5 kg each and placed in different places. We can compare each time variation in terms of shape, texture and color so that we can analyze it. It was found from field experiments that to produce quality briquette dough, the mixing time was 30 minutes with an average power consumption of 2.49 KwH.
