Abstract

Meat is one of the agricultural commodities needed to meet protein needs, because meat contains high quality protein, which is able to contribute complete essential amino acids. The purpose of this paper is to design, analyze the static strength of the frame based on theoretical calculations and simulations on solidwork 2018 software. This machine consists of a frame, reservoir, grinding shaft, transmission, and electric motor. The results of the design obtained a Meat Grinding Machine with Length: 610 mm, Width: 500 mm and Height: 750 mm. The material used is 2024-O Alloy with a modulus of elasticity of 72,400 N/mm2. The load force obtained is 576.32 N. And the value from the analysis is the displacement value of 0.174 mm and for theoretical calculations, the displacement value is 0.176 mm. So, the value of the percentage error is 1.176%. For the von Mises value of 68,970 MPa, and for calculations based on the theory, the von Mises value is 52,499 MPa. So, the value of the error percentage is 0.238%. And for the value of the safety factor obtained a value of 1,087, and for calculations based on the theory, the value of the safety factor is 1.428. So, the value of the error percentage is 0.313%.

Abstract

The learning outcomes of grade VI students at SD Negeri 2 Klunggen are still low, with an average score of 55.24. The formulation of the problem in this study is how the learning process with the Mind Map method can improve the learning outcomes of class VI SDN 2 Klunggen students. The purpose of this study is the Mind Map learning process to improve motivation and learning outcomes of class VI students. his research was conducted on the sixth grade students with a total of 22 students. Research planning is carried out collaboratively with colleagues. The results of the research that occurred during the action research was an increase in the average learning from 55.24 in the initial conditions to 66.67 in the first cycle and 83.33 in the second cycle. In addition, the results of the study are also related to the increase in student learning mastery from 23.81% in the initial conditions to 66.67% in the first cycle and 95.24% in the second cycle. It is concluded that the action through the use of the Mind Map learning model can improve student learning outcomes.

Abstract

Chili plants are plants that are very popular with farmers because they have high economic prices and are easy to cultivate in the highlands and lowlands. One of the chili pest attacks is the whitefly (Bemisia tabaci Gennadius) which is a virus vector that can reduce chili production. Whitefly pest control (Bemisia tabaci Gennadius) still uses chemical pesticides so that alternative controls are needed using vegetable pesticides, one of which is shallot skin extract. The treatment used in this study consisted of 5 treatments namely water control, chemical control and 3 treatments with shallot skin extract concentrations (2%, 4% and 6%) which were repeated 4 times. This study used two application methods, namely the application of shallot skin extract directly to the plant and the application of shallot skin extract directly to the test insect (Bemisia tabaci Gennadius). The results of the study showed that onion skin extract had the highest mortality, namely 27.5% by direct application to plants and 35% by direct application to test insects (Bemisia tabaci Gennadius). at the concentration of shallot skin extract 6%.
