Abstract

Duck eggs are a source of animal protein that has a delicious taste, easy to digest and highly nutritious so that it is loved by many people. In addition, eggs are easily damaged by the length of the trade chain and the improper storage process. The processed form of duck eggs, which until now is the best known and most favored by the people of Indonesia, is salted eggs. This study aimed to determine the effect of soaking salted eggs in bay leaf juice (Eugenia polyantha Wight.) at different concentration levels on the content of free fatty acids (FFA), total volatile bases (TVB) and antioxidants in smoked salted eggs. The experimental design used in this study was a completely randomized design (CRD) consisting of 5 treatments with 4 replications. The treatments consisted of: P0= Duck eggs + 0% bay leaf juice, P1 = Duck eggs + 25% bay leaf juice, P2 = Duck eggs + 50% bay leaf juice, P3 = Duck eggs + 75% bay leaf juice, P4 = Duck eggs + 100% bay leaf juice. The results showed that the effect of using salted egg soaking in bay leaf juice (Eugenia polyantha Wight.) showed a very significant effect (P<0.01) on FFA, TVB and antioxidants. It was concluded that the addition of bay leaf juice with a concentration of 25 to 100% in smoked salted eggs was able to reduce the number of free fatty acids, reduce the content of total volatile bases (TVB) and increase antioxidant activity. The use of the best concentration of 100% bay leaf juice is the lowest FFA 0.10 (%), the lowest TVB 2.32 (mgN%) and the lowest antioxidant 88.59 (mg/g).

Abstract

Stock trading is a popular financial instrument worldwide. In Indonesia, the stock market is known as the Indonesia Stock Exchange (BEI), and one actively traded stock is PT Bank Central Asia (BBCA). However, predicting stock price movements is challenging due to various influencing factors. Investors use fundamental and technical analyses for decision-making, but results often vary. Machine learning, particularly random forest regression and linear regression algorithms, can be used for stock price forecasting. In this paper, we compares these two machine learning methods to forecast BBCA stock prices, aiming to provide more accurate and effective solutions for investor's investment and trading decisions. The evaluation results of cross-validation mean squared error (MSE), root mean squared error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE) for linear regression were 0.12848, 0.35807, 0.29570, and 0.0036%, respectively, while for random forest regression were 27473.76, 158.04, 142.70, and 1.7153%. These findings indicate that linear regression outperforms in forecasting performance.

Abstract

Cabbage waste fermented liquid (Brassica oleracea) is a type of fermented liquid that contains lots of vitamins and other important nutrients that are beneficial for broilers. This study aims to determine the effect of adding fermented cabbage waste to the percentage of weight and length of the digestive organs of broilers including the weight of the proventriculus and ventriculus. This research was carried out from March to May 2021 at the Laboratory of UIN Agriculture Research and Development Station (UARDS) Faculty of Agriculture and Animal Husbandry, Sultan Syarif Kasim State Islamic University, Riau. The research material used 80 DOC broilers (CP 707). The research method was an experiment using a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments consisted of P0 (control drinking water), P1 (2 ml of fermented cabbage waste/liter of drinking water), P2 (3 ml of fermented cabbage waste/liter of drinking water), and P3 (4 ml of fermented cabbage waste/liter of water). drinking water). The parameters measured were the percentage of weight of the proventriculus and ventriculus. The results of the analysis of variance showed that the administration of fermented cabbage waste in drinking water to broilers did not have a significant effect (P>0.05) on the percentage of weight and length of the digestive organs of broilers. The conclusion of this study is that the administration of fermented cabbage waste liquid to a level of 4 ml/liter of drinking water in broilers has not been able to increase the weight and length of the digestive organs of broilers
