<![CDATA[Tofu liquid waste with protein content is one of the wastes that has economic value, because the content of organic compounds and nutrients contained in it is still relatively high. Oyster mushroom is a type of wood mushroom that has a higher nutritional content than other types of wood mushrooms. Market demand for oyster mushrooms continues to increase. The need for oyster mushrooms is still relatively high and its fulfillment is still limited, therefore it is necessary to add nutrients from the outside, where tofu liquid waste can be used as an alternative growing medium for oyster mushrooms. This study aims to determine the extent to which tofu liquid waste has the potential as a substitute for mixing planting media in accelerating the growth of mycelium of oyster mushroom (Pleurotus ostreatus). This type of research is a pure experiment using a completely randomized design (CRD) using 4 treatments (0% concentration, 25%, 50%, 75% and 100%) and 5 replications. Parameters observed were the increase in length, thickness and color of the mycelium. Data were analyzed using 5% ANOVA (Analysis Of Variance) with the help of SPPS for windows program. The results of the value analysis based on the increase in length, thickness and color of the mycelium were 1.737 cm (t-count = 2.911 > t-table = 0.094); thick (t-count = 0.688 > t-table = 0.411) and white (t-count = 1.219 > t-table = 0.001).]]>

<![CDATA[Eggs as a staple food for the community are increasingly in demand because they are very easy to obtain, easy to process and have high protein content. Duck eggs stored at room temperature can only last 10-14 days, after which the eggs have decreased in quality. The purpose of this study was to determine the effect of using betel nut seed solution as a preservative on the storage time and quality of duck eggs. This type of research is a True-experimental study with a Completely Randomized Design (CRD), two factorial, consisting of concentration treatments (0%, 15%, 30%, 45%, and 60%) and storage time treatments (14 days, 21 days, and 28 days) with 3 replicates. Chemical and physical test data were analyzed using the ANOVA test (5%) using SPSS for Windows version 20.0. The interaction of betel nut seed solution concentration and storage time gave no significant effect on the pH value (Fhit = 1.125 < Ftab = 1.375), Yolk Index (Fhit = 1.002 < Ftab = 1.454), and Weight Loss (Fhit = 0.614 < Ftab = 0.638). However, the length of storage of duck eggs had a significant effect on the yolk index (Fhit = 21.821 > Ftab = 21) and weight loss (Fhit = 12,569 > Ftab = 12.001).]]>

<![CDATA[Peanut (Arachis hypogaea L.) is a legume crop and is one of the second highest yielding secondary crops after soybeans. Peanut production in Indonesia tends to fluctuate and is still not able to meet the needs of the community every year. To produce quality seeds, one of the ways that plant breeders do is by crossing. The cross in this study was a peanut cross between the national variety and the local Bima variety. The purpose of this study was to determine the vigor and viability of peanut sprouts from crosses between national and local varieties of Bima. This research is included in pure experimental research. The design used in this study was a completely randomized design. The data in the research that has been collected through observation and documentation methods are then analyzed using ANOVA One Way. Based on the results of the study, the data on viability parameters were obtained, namely: the highest percentage of germination was obtained by F1A seeds (Rhinoceros Variety x Local Bima) with a value of 86.66% while the lowest percentage of germination was F1C seeds (V. Kancil x Local Bima) with a value of 20%. For the parameter of germination speed, the F1 seed which had the highest seed germination speed was F1E (V. Pelanduk x Local Bima) with a value of 2.33/day while the lowest germination rate was F1C (V. Kancil x Local Bima) with a value of 0.58/day. From all research data, it was found that data from all parameters experienced significant variations or differences with P Value < 0.05 in each treatment.]]>
