The Malayan sun bear (Helarctos malayanus) is one of the large terrestrial carnivore species inhabiting tropical forests of Kalimantan and Sumatra. The species plays important role in tropical ecosystems. However, this species faces threats that are mainly driven by human activities in the form of habitat loss and fragmentation due to human development such as settlements, encroachment, logging…
Trichoderma sp. PNE4 has the potency to inhibit the growth of Colletotrichum sansevieriae, the cause of anthracnose disease in the Sansevieria trifasciata plant. Tapioca waste, bran and corn are used as a carrier for Trichoderma sp. PNE4. The objective of this study was to find out the effectiveness of several carrier media, and determine the viability of Trichoderma sp. PNE4 in different sto…

The analysis of durik-durik (Syzygium sp.) from Riau has been done using a DNA barcode namely rpl16 intron. The methods included sampling, total DNA extraction using Genomic DNA Mini Kit Plant (Geneaid), Polymerase Chain Reaction (PCR), electrophoresis, …
Kampar Kiri River is the Kampar River flow which has a function as a source of freshwater fish. Generally the fish species found are consumption fish so that the river is one of the fisheries production centers in Riau and also as a transportation, toilet washing bath, agriculture and household waste disposal. This greatly affects the availability of fish resources in the Kampar Kiri River, one…
Siak Regency is an area that has high vegetation heterogeneity with different habitat types. Differences in habitat types are thought to affect the diversity of cerambycid beetles in the Siak Regency area. The effect of differences in habitat types in Siak District on the diversity of cerambycid beetle species has not been studied. This study aims to determine the diversity of cerambycid beetle…
Lubuk Siam Lake is a Lake that gets runoff flooding from Kampar River. This Study Aims to determine teh content of Pb heavy metal be found in water, sediment, gilss and heart of baung fish (Hemibagrus nemurus) in Lubuk Siam Lake Siak Hulu Subdistrict. Pb heavy metal content was tested using Atomic Absorption Spectometry (AAS) heavy metal analyzer. Pb content of heavy metal that accumulates in w…
Rawa Mekar Jaya mangrove ecosystem is one of the snake habitat, this area is also an ecotourism area. Ecotourism activities have the potential to reduce the habitat quality of wild animal including snakes, thus possibly affecting the diversity of snakes there. Therefore, this research aims to determine the diversity of snakes in Rawa Mekar Jaya mangrove. Data retrieved using the Visual Encounte…
Pandan (Benstonea sp.) is one of the most important plants in Kajuik Lake located in Langgam, Riau Province, Indonesia. This plant has been previously idetified in 2017 with the result that pandan is a member of Benstonea, but has not been identified to species level. Therefore, further DNA barcoding analysis using intergenic spacer located in plant chloroplast genome need to be performed. The …
Mangosteen (Garcinia mangostana L.) from Bengkalis is a commodity fruit native to Indonesia which has the advantage to grow in swampy areas. Limitations of the seed and the slow rate of growth is a challenge in the mangosteen plant propagation. Propagation of shoots in the mangosteen can be produced quickly with nodule induction in vitro. This study aims to investigate the influence and determi…
Mung bean (Vigna radiata (L) R. Wilckzek) is one of the most beloved grains types by consumers. However, the yield of mung beans in Riau Province has decreased since 2011 due to the reduced cultivating mung beans land.
