Design Of Liquid Smoke Equipment With A Capacity Of 120 Ml Per Hour

Bakri Bakri Anuar — 2025-06-30

Liquid smoke is the result of pyrolysis of various types of biomass used in various industrial applications, including food preservation and waste treatment. This study aims to design and test a liquid smoke production device with a capacity of 120 ml per hour using six types of raw materials: coconut husk, coconut shell, straw, rice husk, corn cob, and corn stalk. The graph of the test results shows that the second experiment (test 2) produced a higher volume of liquid smoke than the first experiment (test 1), with the maximum volume reaching 310 ml. Nonetheless, the processing time varies depending on the type of raw material used. The results of this study show that optimizing the pyrolysis process can improve the efficiency of liquid smoke production, both in terms of volume and processing time. Thus, the device design used in this study has the potential to be further developed to increase production capacity and efficiency. Keywords: liquid smoke, pyrolysis, equipment design, production capacity, coconut shell.

Taro Crushing Machine Design Using Aluminum Knife Disc

Sir Anderson — 2025-06-30

There are many agricultural communities, one of which is taro, because the season is suitable for the territory of Indonesia. With the development of appropriate technological advances, technological tools that can process agricultural products can be found, so thinking about how to improve and ease work or process crops or process taro products to increase the selling price even better. The purpose of the research in general is to make it easier to slice taro for chip entrepreneurs, especially taro chips, and can also be operated for cutting or slicing such as tempeh, potatoes, sweet potatoes, carrots, etc. The specific purpose for making this tool is to know the capacity of the taro chopper, to know the components in the taro chopper and to analyze the results of the taro chopper cut. From the manufacture of the tool, it can be concluded that this taro chopper is operated semi-automatically using an electric motor. This machine display method is a single display with 1 type of blade that cuts the taro continuously. The design of this taro chopper machine requires power from an electric motor of 0.54 HP with a rotation of 2800 rpm. The production capacity of the taro machine every 60 minutes is able to stretch as much as 1536 kg.

Stability Analysis of Clay Soil Plus Sand, Cement and DIFA Soil Stabilizer Additives Using Unconfined Compressive Strength (UCS) Testing

Roza Mildawati — 2025-06-30

Tanjung pinang City is located in Riau Islands Province, has coral and kelanauan or kelempungan soil types, but in its implementation there is one location point along 50 meters where the subgrade does not reach the minimum standard density. The purpose of the study was to determine the value of soil density in the form of maximum dry weight and free compressive strength values obtained after a mixture variation of sand, cement and DIFA Soil Stabilizer. The research was conducted using experimental method of laboratory testing. Soil stabilization by mixing native soil plus sand, cement and DIFA soil stabilizer. The compositions carried out were native soil plus sand at 0%, 10%, 20% of the dry weight of the soil, cement 8% of the dry weight of soil and sand weight, and DIFA soil stabilizer 2% of the weight of cement. The testing methods were standard proctor and UCS tests to obtain the density value and free compressive strength value of the stabilized soil. The soil density value based on the standard proctor test is the dry weight value of native soil of 1,410 kg/m3, soil mixture plus 0% sand and 8% cement of 1,450 kg/m3, mixture of 10% sand and 8% cement of 1,470 kg/m3, and mixture of 20% sand and 8% cement of 1,490 kg/m3. The UCS test result of the original soil was 291.50 kN/m2. The test result of mixed soil with 0% sand, 8% cement and 2% DIFA soil stabilizer was 991.25 kN/m2. The test result of mixed soil with 10% sand, 8% cement and 2% DIFA soil stabilizer was 1,241.59 kN/m2. The test result of mixed soil with 20% sand, 8% cement and 2% DIFA soil stabilizer was 1,743.63 kN/m2.

Simulation Of Welding Strength Test Equipment Frame With A Capacity Of 20 Tons Using Solidwork 2020 Software

Torikkuljanna — 2025-06-30

This study aims to analyze the strength of the 20-ton capacity welding test equipment frame using SolidWorks software-based simulation. The simulation evaluates the stress distribution, strain, and safety factor of the frame structure when receiving the maximum load. Analysis using the finite element method (FEA) is performed by modeling the frame along with boundary conditions and loads that match the actual test conditions. The simulation results show that the maximum stresses in the structure are still below the yield limit of the material, so the frame is considered safe to use. The highest stresses are distributed at the top of the frame especially around the load application area, while the bottom and legs of the frame experience lower stresses. The minimum factor of safety obtained in the simulation is 6.6 which indicates that the structure has high reliability against the applied load. Based on these results, the welding test equipment frame design can be said to be strong enough and safe to use for testing with a capacity of 20 tons. However, design optimization can still be done to improve the strength of the structure.
