The Biological subject in class VIII has a fairly high level of difficulty and is closely related to everyday life. One of the class VIII are quite difficult to grasp and is closely related to life is the material excretion system. The characteristics of the material in this excretion system places emphasis on contextual learning process because of the demand to link between the subject matter…
Kepungan sialang is a vegetation system in the Tesso Nilo National Park area which is one of the traditional forest management systems to conserve the remaining natural forest surrounding sialang trees, and also creates a communal nesting site favored by the big bee Apis dorsata. This study aims to reveal the characteristics of forest cover, floristic structure, and physical structure (phy…
A Stingless bee (Tetrigona apicalis) is a bee that is widely cultivated by people in Indonesia. The most important factor in beekeeping is the availability of a source of feed to meet the needs of bees. This research was conducted in Tanjung Sari Village, Meranti Islands Regency, Riau Province. The purpose of this study was to determine the diversity of bee food sources based on the pollen …
Water apple (Syzygium aquaeum (Burm.F.) Alston) is a plant that has properties in healing various diseases because it contains chemical compounds of flavonoids, phenolics, and tannins. One way to propagate S.aquaeum is by leaf cuttings. Vegetative propagation by leaf cuttings allows more seedlings to be obtained than through stem or shoot cuttings. Efforts to increase the success of cuttin…
The area “Hutan Adat Imbo Putui” Kampar Regency, Riau is a tropical rain forest located in Petapahan Village. The soil around the forest area is one of the sources of actinomycetes diversity. Actinomycetes are microbes with potential in the medical and pharmaceutical industries because they can produce various secondary metabolites, one of which is antibacterial. This study aims to isol…
Tembesu (Fagraea fragrans) is a family Loganiaceae including high value timber species that have advantages in terms of ecology and economy. Increasing demand for Tembesu wood, high use intensity results in unbalanced overexploitation with inadequate planting, so that the existence of Tembesu is increasingly threatened. Conventional propagation of Tembesu has several problems so that in vi…
Coconut is one of the economic plants that is widely cultivated by people in Indonesia. It’s thought that the maintenance of stingless bee colonies in coconut cultivations can increase fruit production through pollination services. This research was conducted in Tanjung Sari Village, Meranti Islands Regency, Riau Province. The results of the observation of the condition of the coconut cu…
Citrus (Orange) is one of the important plantation commodities in Indonesia. Oranges have a high morphological variation that may cause taxonomic problems. One of important taxonomic evidence is the characteristics of stomata. This study aimed to investigate stomatal characteristic of Citrus from Pekanbaru, Riau Province. The sampling was carried out using the exploration method. The stoma…
Synthetic plastic has the disadvantage of being difficult to decompose in nature, causing environmental problems. To overcome the problem of accumulation of plastic waste, the use of environmentally friendly plastics (bioplastics) is one solution. Bioplastics are made from natural polymers such as starch, cellulose, and fats. Polyhydroxyalkanoate (PHA) is one of the building blocks of biopl…
Grasshoppers are animals that can be found in everyday life. Grasshoppers are able to live in almost all terrestrial ecosystems. This study airned to determine the orthoptera grasshopper species community in the Rumbio Customary Prohibition Forest. Kampar Regency, Riau Province. Observations were made from August to September 2020 on five different lines: the first line of Koto Naghago, the…
Conventional plastic is difficult to degrade and can pollute the environment. Therefore, an alternative to conventional plastic is needed by using bioplastics that are more easily biodegradable. The purpose of this study was to obtain potential bacterial isolates to produce PHA as raw material for bioplastics from industrial waste of sago and tofu in Riau. PHA-producing bacteria were isolat…

Syzygium cumini L. Skeels or Duwet (Java plum) is a plant that belong to the Myrtaceae family. Duwet plants contain secondary metabolites such as flavonoids, tannins, and contain essential oil. The content of secondary metabolites in duwet leaves has great potential to be used as medicine. Identification of metabolites at the tissue level, synthesis sites or storage sites for pharmacologic…
Several research results stated that some students often experienced conceptions that tended to be wrong on the concepts of Photosynthesis and Plant Respiration. This concept is the most important concept in studies in biology because this concept studies the transfer of energy and matter in an ecosystem. Conception that tends to be wrong or a concept that is different from scientific agreement…
