Abstract

Karakteristik penyerapan air dari biji jagung, sorgum, dan hanjeli  selama perendaman dipelajari pada dua jenis larutan yaitu pH netral dan alkali, serta pada tiga suhu yang berbeda yaitu 30, 45, dan 60 °C.   Persamaan Peleg digunakan untuk mengetahui laju penyerapan air dan kapasitas penyerapan air maksimum serta untuk menentukan kadar air kesetimbangan. Kinetika absorpsi mengikuti hukum difusi Fick. Nilai koefisien difusi meningkat karena peningkatan suhu dan jenis larutan perendaman. Hasil perhitungan nilai koefisien difusi berkisar 1,61 – 1,82x10-11 m2s-1 untuk sorgum; 1,97 – 2,64x10-11 m2s-1 untuk hanjeli; dan 4,80 – 5,66x10-11 m2s-1 untuk jagung. Perendaman pada larutan alkali menghasilkan nilai energi aktivasi yang lebih kecil. Persamaan Arrhenius dapat digunakan dengan baik dalam pendugaan nilai koefisien difusi berdasarkan nilai energi aktivasi dan suhu perendaman.

Abstract

Cherry tomatoes (Lycopersicum esculentum M.) are a type of tomato that many people like because they taste sweet and are rich in vitamins. However, conventionally cherry tomatoes have not been widely cultivated in Indonesia because besides of susceptible to disease, cultivation techniques in open fields are not well understood by many farmers either. This research aims to determine the appropriate size of the nutrient jar and hydroponic system. The experiment used a completely randomized design (CRD) which was arranged factorially with three replications. The first factor is the size of the nutrition jar which consists of 3 levels, namely 500 mL (P1), 1500 mL (P2), and 2500 mL (P3). The second factor was the type of hydroponic system consisting of Wick System (HW), Dry System (HD), and Floating System (HF). The results showed that the nutrient jar size had a positive effect on evapotranspiration, number of leaves, root length, number of flowers, fruit weight, and water content of the fruit.  The hydroponic system significantly affected the number of flowers, root length, fruit weight, and in general the Wick System (HW) had better performance compared to the Dry system (HD) and the Floating system (HF).  The interaction of the two treatment factors was not significant.  The data showed that the 1500mL Wick System (P2HW) was the most optimum treatment, based on the parameters of evapotranspiration/consumption of nutrient (2.6-3 liters), number of leaves 17 leaves), root length (23.4-25.1 cm), and fruit weight (14.1-15.22 grams) as well. Keyword : Cherry tomatoes (Lycopersicum esculentum M.), hydroponic, nutrient jar size. wick system

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.
