Bakso is a type of chicken meat ball that is commonly found in Indonesian cuisine. Currently, chicken meatballs are one of the processed chicken meat products that have a particular taste. The biggest energy contribution comes from protein, which reaches 60 percent, followed by fat as much as 38% and carbohydrates as much as 2%. The high public demand for processed products such as chicken meatballs has resulted in most shops, from stalls, school canteens, grocery stores, to supermarkets selling chicken meatballs. Before the existence of modern meat grinding machines, the process of grinding chicken meat was very difficult, but now, with advances in technology, there are many grinding machines on the market that simplify the process of grinding meat. The business of making and selling chicken meatballs has attracted the interest of several community business groups with small and medium scale businesses. In order for the business of producing and selling chicken to meet public demand both in terms of quantity and in terms of quality, good planning and management is needed. The design method used includes grinding machine product design. The result of the design that has been done is the output diameter of the meat with a size of 5 mm with the appropriate results (fine on average). Where the diameter of 2 mm and 3 mm produces chicken meat that comes out very slowly and is very smooth and causes the meat to melt and the chicken meat comes out fast and smooth. Thus, it can be concluded that a chicken meat grinder machine can grind 1 kg of chicken meat in 1 minute and the appropriate output hole size is 5 mm with a smooth and fast output of chicken meat.

Technological and economic developments are directly proportional to the industrial sector, especially in countries that are still developing. The food industry is one of them. Chocolate is one of the growing foods industri. The research on Comparison of the Drying Rate of Cocoa Beans Using a Dryer with Electricity and Solar Energy was carried out using an experimental method, namely with electricity coming from solar panels and then with electricity from PLN. The test aims to get a comparison of the effectiveness of electrical energy against solar panels. Cocoa beans that will be tested for drying before must be fermented first. The purpose of this test is to determine the drying time in a cocoa bean dryer with electricity and solar panels. This test uses the drying method using solar panels and uses electricity. Heat transfer in this test is conduction and convection. Test results are carried out in two stages. the first stage using electrical energy with the result of drying using cocoa beans weighing 2000 grams with a 271watt heater with the highest temperature of 43.6 0C can reduce the water content by around 59% from the mass of the 2000 gram sample weight of cocoa to 812 grams. The second stage is using solar panels where the drying process is divided into 2 stages, the first 8 hours with solar power and solar panels then the next stage using the help of batteries in the afternoon until evening. This stage can produce dry cocoa beans weighing 800 grams of dry cocoa beans from 2000 grams of wet cocoa beans. Thus, it can be concluded that the best drying using electric power can produce 812 grams of dry cocoa from 2000 grams of wet cocoa.

Palm is a type of palm whose potential for high economic value and can thrive in Indonesia. Nagari Andaleh Baruh Bukik is an area in Tanah Datar District that is a center of palm crop production and has the potential to be developed by its economy. Seeing a promising market, the idea was born to process ant sugar into brown sugar cubes by making a brown sugar cube printer. The manufacture of brown sugar cubes using the manual press method with a pressing system utilizes the principle of the 2nd type of leverage, where the load point is between the power point and the fulcrum. This pressing system works if the lever is pulled by the operator according to the specified depth limit, to restore the position of the lever to its original position is to take advantage of the spring force. It takes about 392 N to press the mold. By doing the calculation so that a mechanical profit is obtained 3 times, the total force required to press is 130.6 N. The safety factor equation is 69.76 N/mm2 ≤ 200 MPa with the largest curved moment being 130.87 N/mm2, so this tool is safe and will not be bent. Power arm length: 34.5 cm, weight arm length: 11.5 cm. Designing components and assembling brown sugar cube printers using the SolidWork application.

This study focuses on the discussion of the correlation of acoustic and dynamic characteristics of hybrid panels, namely Micro-perforated Panel (MPP) and Honeycomb (HC) structures. Acoustic characteristics in experimental studies are obtained by the sound absorption coefficient and Sound Transmission Loss. Meanwhile, the dynamic characteristics are obtained by the mode and frequency response analysis of numerical simulation methods. The results of these two characteristics serve as a benchmark for the development of experimental data studies/analysis. The purpose of this study is to obtain dynamic characteristics using mode and frequency response analysis through the finite element method. The development of this experimental study/analysis data is to overcome the drawbacks of experimental testing. The weakness obtained from experimental studies is that the stages are complicated and require a very large amount of money. The method in this study was carried out by numerical simulation using the finite element method using the Ansys 2019 R3 program. The results of this study obtained dynamic characteristics from the development of experimental study analysis methods using numerical simulations through the finite element method. Numerical simulation on the hybrid panel provides efficiency at the experimental testing stage. The results of the mode and frequency response analysis obtained by numerical simulation methods have similarities in the frequency range of high and low frequency values of sound absorption coefficient and soundtransmission loss.

Indonesia is an agricultural country with vast agricultural land and abundant natural resources. Thus, it is not surprising that the Indonesian agricultural sector has a very important role in economic growth, because this sector has great potential in absorbing a large number of workers as well as supporting food needs. West Sumatra is one of the corn-producing provinces in Indonesia with corn production in West Sumatra Province in 2020 of 935,716 tons or 59,465 tons less than the production target of 995,201 tons. Availability of corn supplies will greatly affect the livestock industry in general. If the supply of corn raw materials experiences scarcity, it will result in stagnation in the availability of animal feed. On the contrary, with the adequacy of corn raw materials, it will encourage the smooth supply of animal feed. This means that corn is very influential on the performance of livestock development and the provision of animal protein which is much needed in improving the quality of human resources. The purpose of this research is to be able to design and manufacture a corn sheller machine. The working principle of this machine is to rotate the shaft which aims to make the corn revolution motion towards the shaft and is held by the retaining wall at the bottom which will separate the corn kernels and the cobs. The research method used is applied research method.

Thus, it is not surprising that the Indonesian agricultural sector has a very important role in economic growth, because this sector has great potential in absorbing a large number of workers as well as supporting food needs. West Sumatra is one of the corn-producing provinces in Indonesia with corn production in West Sumatra Province in 2020 of 935,716 tons or 59,465 tons less than the production target of 995,201 tons. Availability of corn supplies will greatly affect the livestock industry in general. If the supply of corn raw materials experiences scarcity, it will result in stagnation in the availability of animal feed. On the contrary, with the adequacy of corn raw materials, it will encourage the smooth supply of animal feed. This means that corn is very influential on the performance of livestock development and the provision of animal protein which is much needed in improving the quality of human resources. The purpose of this research is to be able to design and manufacture a corn sheller machine. The working principle of this machine is to rotate the shaft which aims to make the corn revolution motion towards the shaft and is held by the retaining wall at the bottom which will separate the corn kernels and the cobs. The research method used is applied research method.
