Riau Province has sandy soils (Dystrudepts) that are often used for oil palm plantations. This soil has a very fast percolation and high leaching risk, so it requires the selection of slow-release fertilizers namely Polyhalite and combined with KCl. The purpos…
ABSTRACT Sweet corn (Zea mays saccharata Sturt.) can be cultivated in acid soils with low nutrient availability. A combination of biofertilizer and NPK is required as biofertilizer alone is insufficient. To maintain microbial effectiveness, this study used Mucuna bracteata as a storage medium for biofertilizers.This research was conducted experimentally using a Completely Randomized Design (CR…
ABSTRACT The decline in maize production in Riau province is caused by the attack of plant disrupting organisms, namely armyworms (Spodoptera frugiperda J. E. Smith). S. frugiperda attacks meize plants in the vegetative phase up to the generative phase. The use of synthetic insecticides can cause negative effects. The solution to reduce the use of synthetic insecticides is to find alternatives…
ABSTRACT Rice plant (Oryza sativa L.) is a rice-producing plant and the main food commodity for the Indonesian population. intensification is one of the efforts to increase agricultural yields by fertilizing using both inorganic and organic fertilizers. The addition of organic materials such as solid waste and biological fertilizers can make the use of inorganic fertilizers more efficient. Thi…
ABSTRACT Shallot (Allium ascalonicum L.) is one of the horticultural crop commodities that is widely consumed by the community because it has various benefits. Shallot production in Riau Province is still categorized as low compared to other provinces such as North Sumatra and West Sumatra.

Freshwater mussel shell waste can act as a calcium precursor in the synthesis of hydroxyapatite. Hydroxyapatite serves as an active component in toothpaste formulation, functioning as an abrasive while also possessing the capability to inhibit the proliferation of bacteria responsible for dental plaque. This study aimed to evaluate the effect of adding hydroxyapatite into toothpaste on its …
Fermented fish sausage is a processed product from the fermentation process, where fish meat is mixed with additional ingredients such as salt, spices, and lactic acid-producing bacteria. Lactic acid bacteria can extend the shelf life of the product, help preserve by preventing the growth of spoilage bacteria, and can even produce food with a distinctive flavor. To accelerate the fermentation p…
