Ovens sold in the market have many features that make them easier to use but are not suitable for the needs of Small and Micro Enterprises (SME), namely large capacity, multifunction, use of gas fuel, energy-saving, and ease to operate. It is necessary to design and manufacture an oven according to the needs of SME users. The purpose of this study is to design, build, assess the feasibility, and evaluate the operating energy usage of the oven. The oven design process uses the French’s model and Quality function deployment (QFD) methods. Experiments to test the oven’s feasibility. The study’s result is that oven design validated user requirements by design experts, manufacturing experts, and users (SMEs). The oven prototype has shown performance to reduce water content according to food products with a distribution permit in Indonesia. The energy consumption of oven prototype has been compared to an electric oven similar capacity that showed that there is an energy-saving of 6.8%. Based on validation of design and product feasibility and calculation of oven energy consumption, the oven meets the small and medium enterprises (SME) users’ needs.

“…FEM has evolved into an effective and widely used numerical approach for engineering analysis and design [5]. The study revealed that the smaller the size of the material, the smaller the value of the safety factor, and the cheaper the material costs when selecting the structural design of a machine based on FEM and assessment of material prices [6]. In addition, the structural strength of mechanical components is only tested under static loading not under thermal load.…”

“…In addition, the structural strength of mechanical components is only tested under static loading not under thermal load. Several finite element method studies [2][3][4][5][6][7][8][9][10][11][12] establish the stress and deformation values of the design. It is quite expensive to test the developed product directly in the laboratory since the mechanical form of the product must be verified.…”

This study aims are to analyze stress and displacement using Finite Element Method (FEM) of the three components design of powder packaging machine. The safety factor (SF) is calculated to compare with the design acceptance criteria, more than two. The frame is made of ASTM A36 steel angle bar, while the camshaft and sealer sleeve of AISI 1018. Steel angle bar widths of 40x40 (mm) and 50x50 (mm) with a thickness of 3,4,5 (mm) use for the frame design variant. The diameters of the camshaft design variants are 0.75”, 1”, and 1.25”. Then, the sealer sleeve variant utilizes thicknesses of 10, 12, and 14 (mm). Loading assumption during adverse operating conditions, such as when there is an obstacle or jam. Through the finite element method results, increasing the thickness of the frame also the sealer sleeve, and increasing the diameter of the camshaft, produced a decrease in the value of von mises stress and displacement. The safety factor for all variants of frame thickness was more than two, indicating that all designs were safe and acceptable. Nevertheless, there is one design failure on the camshaft and sealer sleeve because the SF value is less than two.

“…The design results will be tested statically using software to determine the strength of the chassis design and the factor of safety. Before designing the chassis, several things must be considered as a design reference; here are some general considerations described by Dahlan [2], (1) Types of loads and stresses caused by loads, (2) Types of component movement, (3) Type of material, (4) Shape and size of components, (5) Ergonomics, (6) Safety of operation, (7) Cost.…”

Compared to conventional vehicles, the advantages of electric vehicles are more significant acceleration, no exhaust emissions, making electric vehicles more environmentally friendly, minimal maintenance because there are not many components used in electric cars. This research method is used to develop the chassis design of an electric trike, and then the chassis design is analysed using Solidworks software. The chassis with a thickness of 2.4 mm weights 29.6 kg with a maximum value of stress, displacement, strain, and other factors. Safety as follows: 7,582 x 107 N/m2, 2,567 mm, 3,368 10−4 and 3.5, 2 mm thick chassis weighs 25 kg with maximum stress, displacement, strain, and safety factor values as follows: 1.079x108 N/m2, 3.160 mm, 3.981 10−4 and 2.5 then the chassis thickness of 1.6 mm weights 20.3 kg with the maximum stress, displacement, strain, and safety factor values as follows: 1.809 x 108 N/m2, 4.190 mm, and 9.388 10−4. Chassis with a thickness of 2 mm using a rectangular tube and ASTM A53 material has a safety factor value that is by the requirements and the maximum stress value on the chassis does not exceed the allowable stress value and weight.
