Abstract

Along with population growth, diverse preferences and lifestyles, fluctuating prices, and increasing consumer financial capabilities, the need for animal protein-based foods such as meat has also increased. Increasing public awareness of the importance of balanced nutrition, population growth, and increasing financial capabilities of the community are factors that cause an increase in the desire to consume beef. Given the increasing need for meat and bones with relatively high community needs, special equipment is needed, namely a bone cutting machine, to help cut bones quickly. To make this machine, data was collected through observation and literature studies. The author used Solidwork 2020 to make the shaft of this bone cutting machine, then performed calculations manually. Based on the results of the shaft design, the torsional moment on the drive shaft was calculated as 13045 kg, the permissible shear stress was 4.1 kg/mm2, the main shaft diameter was 24 mm, the shear stress was 4.81 kg/mm2, the shaft length was 260 mm, and the torsional deflection was 0.72°. The results of the functional test of the bone cutting machine shaft can run according to plan. The results can be used as a teaching tool for mechanical engineering students, and the design of the cutting knife can be improved so that it can be used optimally and benefit society.

Abstract

The development of sugar palm plants in Indonesia is very prospective. Can increase farmers' income from sugar palm farming, as well as preserving natural resources and the environment. The application of post-harvest technology for palm fruit that is not yet optimal causes the production of palm fruit to be very low. So researchers are interested in designing a tool for processing kolang kaling. The general aim of this research is to design a fruit processing machine for kolang kaling fruit. The specific aim of this research is to analyze, design and build flatteners for kolang kaling machines. This research method uses the experimental method with a combination of qualitative and quantitative approaches, while the data analysis technique used uses quantitative techniques. The measurement results show that the length of time for peeling, flattening and separating palm seeds required by the designed machine is faster than manually. The time required by the machine designed to peel 10 kg of palm fruit is an average of 38.6 seconds, while the manual requires 470 seconds. After stripping, the flattening process is carried out. The results obtained in one rotation of the flattening shaft are that it can flatten 180 palm fronds in a time of 2 seconds. In conclusion, the designed palm fruit flattening machine can flatten palm fruit without taking a long time. The time required to peel palm fruit using a designed machine is more effective than the manual method.

Abstract

The Cantilever structure is a structure that is commonly found in general. This structure usually consists of a beam that is supported or fixed at one end, while the other end of the material used as a Cantilever beam works openly (without support) and has a specific load at its end. When a load is applied to the open side, the supported end will experience a moment that varies in value depending on the applied load. This type of structure is widely used, generally in the installation of CCTV in open areas and in street lighting. Based on this background, the author aims to conduct research related to the planned material strength, namely carbon pipes. In addition, the research is conducted to minimize excessive expenditures, meaning that the goal is to design something that is useful, affordable, and has good durability or resilience in its operation. In this study, the method used is data collection through literature studies, interviews, or direct observations of the positions of the poles that have been installed along the passed roads. The result of this research is a robust yet inexpensive single cantilever structure, thus it can be concluded that a good, strong, and load-resistant structure does not always have to be made at a high cost.

Abstract

Corn is a superior commodity owned by Indonesia. Apart from being a staple food, corn kernels are also used as chicken feed by grinding them using a grinding machine. But the processing of corn as animal feed is still relatively expensive. Breeders usually process corn to the mill because they don't have a grinding machine. Meanwhile, buying a grinding machine is not cheap. So to increase productivity and effectiveness in the livestock sector, it is necessary to develop technology or tools in this field. One of the technological developments that can be applied to this sector is the use of grinding machines for corn kernels. We made this machine with the aim of increasing efficiency and saving on animal feed costs. The design of this machine is carried out through the process of designing, selecting and calculating components, the stages of making and assembling the whole, as well as testing the machine. The machine was designed using Autodesk Inventor software to help design the whole. The control and electrical systems are designed using the Simurelay application. This machine has specifications of 250 watt motor power, 712 RPM rotation and 3.29 Nm torque which is capable of grinding dry corn kernels up to 30 kg/hour.

Abstract

Maggot black solder fly (maggot black solder fly) is the larvae of the black solder fly, many are found in various tropical countries, especially in Indonesia. On average, people in Indonesia dispose of food waste about 300 Kg every year, the amount of food waste is a problem that must be addressed. resolved Utilizing organic waste as a feed medium for black solder fly maggots is one way of processing and utilizing organic waste. The main driver of this machine is an electric motor. Power is transmitted through the pulley and the V- belt to the gearbox and then shaft to generate rotation. Here the electric motor and belt-pulley transmission have an important role. Namely, the electric motor as the main driver and the belt-pulley act as the power transmission system,which is where the selection of a V-bel for transmisi power has the advantage of producing greater power at a relative low voltage. So on this occasion the author designed a V-belt transmission, the pulley-shaft that is right for the black army fly maggot dryer.

Abstract

Dodol is a traditional Indonesian food made from glutinous rice, palm sugar, coconut milk, salt, and water. All the ingredients are mixed and stirred until reaching a certain thickness, usually requiring 4-8 hours of cooking time. During the mixing process, dodol must be continuously stirred to prevent it from burning or forming a crust. This design aims to create a machine that can assist in the dodol production process, particularly in the stirring process, to make it more effective and efficient. The method involves designing a dodol stirrer machine frame. The design of this dodol stirrer machine frame uses Autodesk Inventor Professional 2023, with a material of 4x4 cm angle iron with a thickness of 3 mm, capable of supporting a load of 10 kg. The stress analysis results for this dodol stirrer frame are sufficiently safe, with a value of 29.5 MPa, compared to the maximum limit of 147.3 MPa. The results from the frame manufacturing process, using welding with an SMAW machine and E6013 electrodes, show that the frame can support each component and does not experience excessive vibration when the dodol stirrer machine is operational.

Abstract

In the process of harvesting rice, farmers take rice grains or grain to dry. For small-scale farmers, grain drying is done manually with the help of solar heat. It is not effective because it depends on weather conditions. Rice grain drying machines on the market are generally for large capacities. This machine is not suitable for small scale farmers. Based on this background, a rice grain drying machine was designed for small production scale farmers. The limitations of this study only discuss the construction of the engine frame. The stages of the research carried out are; determine the initial specifications of the rice grain drying machine, make a design and test the design of the machine frame using Autodesk Inventor Professional 2017, manufacture the frame of the rice grain drying machine.
