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.

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.

Papaya is one of the fruits that are liked in the community because of it has a sweet taste and rich in vitamin C. In Indonesia papaya is abundant and the price of it is relatively low so that papaya gets wasted easily. Therefore, it is necessary to process the product to extend the shelf life and increase the value-added papaya fruit. Papaya flour is a product of new innovations of flour from the fruit besides papaya flour is food processed products to increase the value-added agricultural produce. In this study used the temperature treatment and type of papaya, with successive research procedures namely taking papaya fruit, peeling, slicing, soaking, drying, grinding, and sieving. The results showed that the temperature of drying can affect the moisture content of papaya flour, color, aroma, and vitamin C. The best quality of papaya flour is at 70°c, which is 23 with the desired color and aroma, resulting in an average water content of 4.9678% and vitamin C content that tends to be higher with a value of 420, 0667 (mg/100g). Drying with papaya type treatment does not significantly affect the moisture content of flour, color, aroma and vitamin C content. Keywords: Aroma, Drying, Flour, Papaya, Vitamin C

In Lampung cassava stem waste is abundant, its existence is very disturbing, it is only thrown away and burned, it has not been utilized. Its use as an insect repellent is one of the value-added treatment efforts. The purpose of this study was to study the effect of tapioca glue adhesive concentration on the characteristics of mosquito coils at several concentrations of cassava stem powder and nutmeg powder. The treatment, the concentrations of cassava stem powder, nutmeg powder, and tapioca glue adhesive were; a) 16.67%, 26.04%, 58.34%, b) 16%, 24%, 60%, c) 15.38%, 23.07%, 61.53%, d) 14.81 %, 22.23%, 62.9%, and e) 14.28%, 22.32%, 64.28%. This research was conducted to study the physical characteristics (moisture content, density, shatter resistance index, combustion rate, smoke distribution, and organoleptic tests). The method used in this study was a completely randomized design measured using the Indonesian Industrial Standard (SII) No. 1113-84. The results showed that the variety of treatments with the addition of tapioca adhesive in the manufacture of mosquito coils had a very significant effect on moisture content, density, shatter resistance index, and burning time.

This study aims to determine the effect of substrate composition on biogas production from a mixture of cow dung and elephant grass using semi-continuous digester. Fresh cow dung and elephant grass were obtained from Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. Elephant grass was knife-chopped, crushed using a blender and then mixed with cow dung at a total solid (TS) ratio between elephant grass and cow dung varies from 35:65 (P1), 40:60 (P2), 45:55 (P3), and 50:50 (P4). This mixture was then diluted with tap water until its TS content reach 5% and was used as substrate. Four semi-continuous digesters (labeled as P1 to P4) having a capacity of 36 L and working volume of 28 L were initially loaded with 22 L of diluted fresh cow dung (dilution ratio of 1:1) as a starter (source of bacteria) and were left until stable condition. When the biogas was produced, the prepared substrate was added daily into the respective digester at a loading rate of 500 mL.d-1. Parameters to be observed included daily temperature and pH of the substrate, daily biogas production, TS and VS content, and biogas quality. The results showed that the digester worked at average pH of 6.9 and the daily temperature 26.3 to 29.7°C. The total biogas production for 60 days was 608.4, 676.8, 600.0, and 613.3 L, respectively for P1, P2, P3, and P4. Biogas yield after the substrate achieving the designed composition was 254 (P1), 260 (P2), 261 (P3), and 271 L.m-3 of the substrate (P4). The addition of elephant grass up to 50% could maintain high production of biogas.
