i SUMMARY Education is one of the areas that continues to change along with the development of technology. This is marked by the entry of the digital revolution era so that digitalization is very close in all aspects including education. The quality of teachers will affect the results of graduates from students obtained and teachers are people who play an important role in the implementation …
Coastal mangrove natural resources are very diverse, including microorganisms. Phosphate-solubilizing bacteria (PSB) are one of the microorganisms that can be utilized from the mangrove ecosystem. PSB can be used as a biofertilizer in agriculture to reduce excessive use of chemical fertilizers. The aim of this research is to isolate and characterize PSB from sediment and mangrove rhizosphere sa…
Bengkalis Island is one of the islands where 85% of the landscape consists of peatland, originally covered by native peat swamp forests. Over the past five decades, deforestation in this area has led to the near-total loss of this native vegetation. This study aimed to analyze the remaining fragments of peat swamp forest and characterize their ecological features. Field data were collected in t…
Staphylococcus is one of the microorganisms that often cause skin infections. The continuous use of antibiotics can lead to the possibility of resistance. Plant extracts such as Mangifera sumatrana and Ruellia tuberosa have the potential to inhibit the growth of pathogenic bacteria. Both plants contain bioactive compounds as antibacterial agents. The aim of this study is to determine the antiba…
The diversity of ants is influenced by habitat variations, as ants are highly sensitive to environmental changes. Ecological factors such as vegetation and microclimate can affect their distribution and abundance. This study aims to examine the composition, diversity, and evenness of ant species across different habitats within the University of Riau area. The research on ant species diversity …
Fiddler crabs (Uca spp.) have an important role in maintaining the balance of the food chain and nitrogen cycle in mangrove ecosystems. The Tanah Merah Village community utilizes mangrove wood in their daily lives which can damage and loss of mangrove vegetation ecosystems. Mangrove damage can cause loss of habitat for various types of aquatic biota, one of which is the fiddler crab. This study…
Feed consumption greatly affects chicken growth. Local feed ingredients have the potential as poultry feed ingredients, such as fermented cassava peel and papaya leaves. This study aims to determine the effect of providing fermented cassava peel and papaya leaf flour feed ingredients on the growth of native chickens, including weight gain, feed consumption, feed conversion, and protein consumpt…
Fusarium oxyforum f. sp cubense (Foc TR4) is agent of Fusarium wilt disease that significantly threaten banana existence. Two banana cultivars, awak and lilin, have been previously reported potential resistant against Fusarium wilt disease. NBS- LRR (Nucleotide Binding Site-Leucine Rich Repeat) gene is the largest group of R genes that play an important role in disease resistance. Purpose of th…
This research, conducted in Sepahat Village, Bengkalis Regency, Riau, aimed to reveal the morphological and morphometric characteristics of Avicennia alba pneumatophores in intertidal habitats experiencing sediment accretion. Pneumatophore samples were collected along transect lines, set at 10-meter intervals perpendicular to the coastline. From 34 excavatable pneumatophores, findings showed th…
Fusarium wilt disease caused by the fungus Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc TR4) is one of the main diseases of banana plants that can significantly reduce productivity and quality bananas. Previous study showed that three banana cultivars (susu merah, nangka and batu) were potentially resistant to Foc TR4. Therefore, purpose of this study was to analyze NBS-LRR sequence o…
Plankton are microscopic organisms that live on the surface of the water, whose movement follows the current, and can serve as bioindicators of aquatic ecosystems. The tributary of the Rokan River is located near residential areas, meaning various human activities can potentially affect the surrounding water quality. This study aims to identify the types of plankton that function as bioindicato…
Tetracera scandens (L.) Merr. That commonly known as ampelai kijang, is a plant traditionally used to treat respiratory disorders, hepatitis, diabetes, and HIV infections. In addition to its cultural significance, this plant contains various secondary metabolites with pharmacological potential. However, studies on its active compounds and applications is limited. This study aimed to characteriz…
