Published: February 2020

Abstract
Soybean commodity is an essential and strategic food crop because food is an essential need for human beings. Aceh is one of the provinces in Indonesia which has become the center of soybean production. However, in recent years, Aceh’s soybean production has declined; this is due to the growing interest of farmers in soybean farming. This study aims to analyze the causes of reduced interest of farmers in soybean commodity farming and to map farmer’s interest in soybean farming. The research method used was descriptive qualitative and collecting data using survey techniques. The results showed that soybean farmers in Pidie Jaya District had good interest and knowledge about soybeans, while soybean farmers in Central Aceh Districts and East Aceh Districts had low interest in soybean affairs and quite good farming ability. The cause of the reduced interest of farmers in soybean business decreased by the low selling prices at the farmer level, pests, prices, and also the limited market that accepts soybean commodities. The percentage of soybean farmers in Aceh Province, which still operates soybeans in Aceh Province, is 27%, while 73% have switched to other commodities.

Abstract
A series of study aimed to improve egg production, egg quality and immunity resulted by cross-breeding with Arab chickens and laying chickens has been observed on 400 chickens of 5-month old of hens was used and treatment was divided into 2 groups: medium and heavy type hens. Randomized Block Design was used and hens were fed on a laying diet contained 18% of crude protein content and 2900 kcal/kg of metabolism energy. Parameters observed were the number of daily eggs (hen/day), clutch, egg weight, egg shape, shell thickness, Haugh unit (HU) and the total percentage of egg production during one production cycle. Immunity was observed by thymus size and time of thymus regression. The results showed that daily and total egg production, clutch spacing, egg weight, egg shape, hemp thickness, Haugh unit (HU) of egg in both heavy and medium type were significantly higher than pure local chicken. However, all the parameters of egg production and egg quality on the type of weight were significantly higher than the light type. In terms of immunity, time of thymus regression on crossbreed hen type occurred at 14-16 weeks of age. It concluded that crossbreeding between local chicken increased egg production and egg quality on derivatives of local chicken. It was also informed that the immunity of derivatives of local chicken resulted by crossbreeding against endemic diseases was better than that of in natural breed chicken.

Abstract
Research on the optimization of the quality and antimicrobial ability of yogurt using a combination of starters (Lactobacillus acidophilus and Streptococcus thermophilus) and dates puree with different levels has been carried out to determine the changes in the quality of yogurt in terms of lactic acid levels, protein content, syneresis and also looking for an antimicrobial ability which was measured based on of inhibition zone formed against the tested bacteria (E.coli and S aureus). A completely randomized design (CRD) factorial pattern was applied consisting of 2 factors, those are factor A which is the level of starter, a1 = 2.5 percent, a2 = 5 percent, and factor B which is the level of dates puree namely b0 = 0 percent, b1 = 10 percent, b2 = 20 percent and b3 = 30 percent. The results showed that the level of dates puree had a very significant effect on lactic acid levels but not so with the starter level. The combination of treatments (P <0.01) affects the protein content but there was no interaction between treatments. Furthermore, there is interaction between treatments and it decreases the syneresis value significantly. It can be concluded that the levels of lactic acid, protein and syneresis of yogurt still have the best quality obtained in the treatment of 5 percent starters and the addition of 20 percent of dates puree. On the other hand, it had a weaker antimicrobial ability
