Abstract

Soybeans and mung beans are legumes that can be processed into various types of food or complementary foods. One of the processed products made from soybeans or mung bean which can be used as a half product is soybean flour or mung bean flour. This study aims to analyze the effect of differences in RPM on the performance of the disc mill for grinding flour products and the level of fineness of the resulting flour products. The study used a Factorial Completely Randomized Design (CRD) which consisted of 2 factors, namely the rotational speed (RPM) and the material. The rotational speed consists of 3 treatment levels, namely 1186 RPM (R1), 1862 RPM (R2), 2495 RPM (R3). The type of material consists of yellow soybeans (K1), black soybeans (K2) and mung beans (K3). The research parameters consisted of flouring capacity, flour moisture content, flour yield and flour fineness. The data were analyzed using the ANOVA test, followed by the BNT test at a significance level of = 5%. The results showed that RPM and material affected the flouring capacity, moisture content and flour yield. The highest flouring capacity was flouring mung beans with a speed of 2495 RPM (R3K3) of 41.77 kg/hour, while the lowest capacity was at a rotational speed of 1186 RPM. for yellow, black and green soybeans. The water content of mung bean flour (10.87%) was higher than that of yellow and black soybean flour. The level of fineness at RPM 2495 on yellow soybeans, black soybeans and green beans produces flour with a medium fineness level. Keywords: Flouring Capacity, Level of Fineness, Mung Bean Flour, Soybean Flour, Yield.

Abstract

Eggs are one of the sources of protein, fat, minerals, and vitamins that are good for the body. Eggs are prone to deterioration in quality caused by physical damage in the form of cracks that can occur during packing, transportation, and storage. One way to prevent damage is by the salting method. Therefore, it is necessary to soak in a salt solution to become salted eggs. The purpose of this study was to determine the effect of the level of salt concentration and temperature during the immersion of eggs in a salt solution to obtain quality salted eggs. The temperatures used in this research of 50ᵒC, 55ᵒC, 60ᵒC, and 65ᵒC, and salt concentrations of 15%, 20%, and 25%. The parameters observed were the measurement of the salt concentration of the salted egg, the changing color in the salted egg yolk, and the taste test for the saltiness of the salted egg. The results obtained by soaking salted chicken eggs at 60ᵒC at a concentration of the salt solution (15%, 20%, 25%) have met the SNI standard quality of 2% because the higher the concentration of salt solution given, the salt content in the egg will also increase. The taste level of saltiness in salted egg chicken obtained an average score of 3 with the taste of egg with salty egg, in which the salt solution increases according to temperature and concentration. The color of the eggs produced at 60ᵒC and 65ᵒC changed from normal yellow to orange-colored yolk eggs. The increase in temperature and the concentration of different salt solutions on the salted egg yolk color is affected by diffusion currents, and It causes the taste of the salted egg to turn salty. Keywords: Chicken Salt Eggs, Salt Solution, Soaking.

Abstract

The development needs of the population that continues to increase cause a mismatch in land use. This can make it possible to reduce water catchment areas in any areas with dense building growth. The use of cement in both housing and road construction results in reduced water absorption areas because cement has properties that make it difficult to absorb water, so water will become stagnant. Therefore, a cement substitute is needed to cover the shortage of cement. The addition of corn cobs in the paving block mortar is expected to increase its water absorption without reducing the compressive strength of the paving blocks. This is done to reduce corn cob waste and save on staple food costs. as well as being used as a useful product innovation in reducing corn cob waste. After printing is complete, the porous paving blocks are dried in the sun and conditioned for approximately 21 days, then the porous paving blocks are ready to be tested. The experimental design consisted of 4 treatments, namely C1, C2, C3, and C4. For the density test, values were obtained with an average of 1.327 g/cm3 – 1.628 g/cm3. For the infiltration test, a value of 0.274 mm/s was obtained. Whereas the visible test is obtained with the appropriate form of paving texture obtained on factor C4 because the resulting texture is good and there are no gaps or defects when the paving has been printed. The highest value from the water absorption test occurred in the C4 treatment with a value of 23.91%. The effect of corncob waste on Porous Paving Blocks in this study is that the more corncob waste fiber is used, the more porous paving block cavities will be, and vice versa if using less corncob waste fiber, the pore cavities will be larger. produced on porous paving blocks will be less. Keywords: Corn Cogs,  Paving block Porous.

Abstract

The multi-purpose animal feed chopping machine is one of the feed chopping tools that many farmers use to help speed up the chopping of raw materials that will be used as animal feed. The chopping machine can be operated optimally if the machine is ergonomic so that it is safe and comfortable to operate. This study aims to analyze the ergonomics of a multi-purpose animal feed chopper in terms of anthropometry, operating workload and the level of work fatigue specifically for the chopper. This research uses quantitative methods which are supported by literature studies regarding the design of creating machine dimensions. The parameters in this study are: (1) anthropometric data consisting of Standing Finger Tip Height (TJUB), Standing Vertical Reach (JVB), and Standing Horizontal Reach (JHB); (2) the recommended weight limit that can be lifted by the operator (RWL), and (3) cardiovascular load (CVL). The research results stated that the height of the chopper hopper (100 cm) was classified as ergonomic because it was still between TJUB (66.10 cm) and JVB (183.95 cm). The operator's position from the hopper should not exceed JHB (66.00 cm). The recommended load limit (RWL) is 5.38 kg. Operation of the machine chopper section does not cause work fatigue with an average CVL of 10.71% (≤ 30%). Keywords: Anthropometry, CVL,  Pulse Rate, RWL, Work Fatigue.
