Mangrove (Rhizophora sp.) is one of timber forest products that have long been used and marketed traditionally in Tembilahan Subdistrict. Wood of Rhizophora sp. is utilized because it has use value needed by the inhabitants as a raw material for building construction. The high need for wood of Rhizophora sp. while the use value is still low leads to continuous exploitation. This research is conducted as a basis to measure how far the inhabitants value the existence wood of Rhizophora sp., especially in Tembilahan district through identification of determinants wood of Rhizophora sp. price. The purpose of this research is to identify the determinants factor wood of Rhizophora sp. prices in the market of District Tembilahan Indragiri Hilir. The approach being used in this research is Descriptive Qualitative analysis method. Data were obtained from in-depth interviews, field observations and document studies. Informant retrieval was done by Snowball Sampling and Census. The selling price wood of Rhizophora sp. offered to consumers varies considerably. The selling price wood of Rhizophora sp. in Tembilahan sub-district is determined by the interaction of demand and supply in the market. The traders wood of Rhizophora sp. in Tembilahan sub-district are the price taker and the established markets are perfect competitive markets.

Rhizophora mucronata is mangrove that has called propagul fruit type. The part that extends to propagul (hypokotil) served is as a food reserve while the Propagul germinate and become seedlings. The type of vivipari propagul is propagul which has germinated before falling from the tree. The Rhizophoraceae propagul has germinated in the fruit, bugles and expands from the fruit when the fruit is still above the mother tree. The purpose of this study was to determine the success rate at nurseries and the best cutting rate of propagul. This research was carried out with a completely randomized design method (CRD) with 4 treatments that is; (P0) without propagul, (P1) propagul cutting 25%, (P2) propagul cutting 50%, (P3) propagul cutting 75%, with triplicate each experiment consisting of 10 plants, with the total of 120 units of plants used. Based on the results of the research, propagul cutting did not affect the success nursery rate by showing the yield of 100% seedlings, the best propagul cutting presentage is 25% with a growth rate of 6.91 cm.

Private forest of Aritonang village is on customary land which is the inheritance of the ancestors in the form of gift/wages by Raja Aritonang to Ompu Guru Sukkunon (a descendant of the Ompusunggu clan) and Ompu Guru Solupa (a descendant of the Rajagukguk clan) are managed based on customary rules. The purpose of this research was to identify the customary rules that apply and to find out the benefits of customary rules in the management of private forests in the customary land of the village of Aritonang. This research was conducted in Aritonang village, Muara Distric, North Tapanuli Regency in April - May 2019. This research used purposive sampling technique to selection of informants. Namely the male lineage and the female lineage of Guru Sukkunon and Guru Solupa who live in hamlet 1 of Aritonang village as much as 36 families, Non-descendant communities Ompu Guru Sukkunon and Ompu Guru Solupa (relatives) who are domiciled in hamlet 1 of Aritonang village as many as 6 families and Batu Binumbun village community who border directly with customary land of Sihuting in Aritonang village as much as 1 family. And this research used qualitative descriptive analysis to analyze the data. Customary rules that apply in the management of Aritonang’s Sihuting private forest cover the process of granting and inheriting management rights of the land land, the time span of use and omission of land, types of plants that are allowed to be planted and/or cared for, yields, establish houses, and determination of sanctions for violators of customary law. The benefits of customary rules in the management of Aritonang’s Sihuting customary forests are the maintenance of order and justice in the process of granting and managing the management rights of customary land.

In visual way, distinguishing mangrove land cover located in Kembung river Bengkalis is hard to do especially if it is using far remote sensing technology. However by applying spectral analyze method, this problem is possibly fixed. It started by taking area sample (training area) 3x3 pixels as many as 10 areas for each classes of land cover, then the result obtained is analyzed by statistical variability test before continued to DMRT test to measure the ability of separation by using separability. Based on the analysis of variability to the spectral value of sattelite vision Sentinel-2A that F-hit (17,626) higher than F-tab (1,98), it showed the treatment has significant effect. The result of DMRT test on reflectancy value of spectral sattelite vision sentinel-2A can be classified into five spectral groups and DMRT test to the mangrove land cover consisted of four groups. Meanwhile, based on separability test there are 36 class pairs, 32 (90,9%) can be separated each way, while 4 (9,1%) can not be separated.

Alstonia scholaris contains flavonoids, tannins, triterpenoids, resins and alkaloids. Alkaloid compounds, tannins and flavonoids of plant origin can inhibit weed growth. Alkaloid compounds, tannins and flavonoids work by suppressing the hormone auxin and the hormone gibberelin so that weed growth is inhibited. This study aims to determine the potential of Alstonia scholaris leaves in inhibiting the growth of weed Cyperus rotundus. The inhibition of Cyperus rotundus growth can be seen from changes in leaf color/population phytotoxicity, number of leaves, and height of Cyperus rotundus. The research used Cyperus rotundus leaves which were mashed into flour and then extracted by macerating with alcohol 96% . The results of the extract of Cyperus rotundus leaf flour consisting of a concentration of 0 g/l (control), 25 g/l, 50 g/l, 75 g/l, and 100 g/l were applied to Cyperus rotundus. Pure extracts are given with different concentrations to determine the concentration that is effective in suppressing the growth of Cyperus rotundus. Vegetable herbicides of Cyperus rotundus leaves with a concentration of 50 g/l became the solution to control the enchanted grass weeds that are environmentally friendly without using synthetic herbicides. With the results of phytotoxicity P2= 40.00%, wet weight P2= 1.53 g, and dry weight P2= 0.91 g.

Unmanned aerial vehicle is one way to get the information of spatial data that photographed in detail small objects on the land with coverage area that is not too broad. The photo shoot was done in the Riau University Arboretum and surrounding areas. The location of the photo shoot on the research including scientific development zone to study forest ecosystems, activities of Student Affairs and the place that usually visited by community. This research aims to mapping and to know the land cover in the Riau University Arboretum and to know value of the accuracy test of the aerial photography from the unmanned aerial vehicle. The aerial photography is analyzed by visual interpretation, the maximum scale based on spatial resolution and use omission commission testing accuracy to compare the value of the observed object in the field and aerial photograph. The bounderies of Riau University Arboretum is not in the field physically, so the Riau University Arboretum as a landmark. The result of the maximum scale is 1:100 with 2.77 cm spatial resolution, so it seems clear the land cover in the aerial photography i.e. vegetation, buildings, and undeveloped land. The result of accuracy test that was conducted showed that the percentage of accuracy reaches 95%, so that the data from the unmanned aerial vehicle can be utilized for mapping a region.
