Yoghurt is one of the milk product obtained by fermented of milk with lactic acid bacteria (LAB). Nowadays, many people diversify yoghurt products so that they become more diverse, such as replacing sucrose. One of the alternative materials to replace sucrose is by using palm sap. Sucrose-rich palm sap can help LAB use the sucrose in the sap as an energy source and can carry out the fermentatio…
Yoghurt is a product obtained from fermented milk. Milk components containing lactose are used as a source of bacterial proliferation. One of the milk used in making yogurt is skim milk. Skim milk is a substrate used as a medium for growing bacteria. Making yogurt also requires sucrose as an energy source for lactic acid bacteria. Sucrose can also be obtained from palm sap as a sugar substitute…

Mucuna is an important and very useful ground cover crop for rubber and oil palm plantations. Mucuna has a long dormancy period, which is 1 – 2 months after the harvesting process. The use of chemical solutions is one of the effective ways to break dormancy. Solutions commonly used to break dormancy include potassium nitrate solution. The purpose of this study was to determine the germination…
Soybean (Glycine max (L.) Merrill) is one of the food crop commodities that play an important role in meeting national food needs, soybeans are one of the sources of vegetable protein that is quite affordable, when compared to other protein sources.

Fluctuations in cabbage (Brassica oleracea var. capitata L.) production in Indonesia are caused by several factors, one of which is the attack of cabbage crop caterpillar (Crocidolomia pavonana F.). Control using synthetic insecticides is the main choice of farmers in controlling Crocidolomia pavonana F., but it turns out that it can cause negative impacts such as pest resistance, recurrence, k…
Biofertilizer viability will decrease, a carrier material is needed that can maintain the shelf life of the biofertilizer. The carrier material used in this research as a storage medium was M. bracteata. This research aims to obtain the best shelf life from long storage of biofertilizer to support the growth and production of sweet corn. The research was conducted experimentally using a complet…
The low productivity of soybeans in Indonesia, especially in Riau Province, is due to suboptimal cultivation techniques and a decrease in nutrient levels in the soil.
