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.

Antochephalus cadamba is a local Indonesian plant that grows very fast and can thrive in tropical forests. Good quality Antochephalus cadamba seeds are needed to make sure the success of the planter and good results. Local Micro Organism (LMO) is a solution of the decay of organic materials derived from plant residues, animal feces, and humans, which contain more than one element. Local Micro Organisms are micro-organisms that are used as starters in making solid organic fertilizers and liquid fertilizers. The aim of the study was to find the effect of Local Micro Organism fertilizer on the growth of Antochephalus cadamba seedlings and the best dose of LMO fertilizer to trigger the growth of seedlings. This research was carried out with an experimental method using a non factorial Completely Randomized Design, LMO fertilizer consisting of five treatments with four replications, to get twenty experimental units. The results that the application of LMO fertilizer on the growth of Antochephalus cadamba dose is best 60 cc/plant, by showing the result of 100% percent of life seedling, growt of plant height is 15,03 cm and dry weight of plant is 35,11 g.

Scorodocarpus borneensis becc. is one of the type that is increasingly endangered in natural forests. Borneensis is a special type of wood, especially in Riau, so it is used as a raw material for community industry such as shipbuilding, masts and door frames. The cultivation efferts of resulted in the use wood in nature as a place for the preparation of wood, the effect of planting media composition on growth of Scorodocarpus bornensis Becc. the composition of the best growing media for growth of S.bornensis Becc. Extract the experiment was done by using complete randomized design (CRD) consisting of 4 treatments. Each treatment consisted of 3 replications and used 10 replications each time, with a total total of 120 pieces. Response measured to see the influence of S.bornensis Becc. Revocation on seedling growth is the percentage of seedling life, high seedling increase, increase in the number of leaves on seedlings, dry weight and top root ratio. The difference in the composition of the planting media affects the growth S.bornensis Becc. On average media compositions (clay + trichokompos 1: 1) with the finest results. The P1 (clay + trichokompos 1: 1) treatment showed the best result as a media composition S.bornensis becc. are percentage of live seedlings 93,3 %, high growth of 20,63 cm, and dry weight of 7,48g.

In 2015 a major fire occurred again, one of them in the Rimbo Panjang Village Tambang Subdistrict, Kampar Regency. Until the year 2016-2017, cases of forest and land fires in the Rimbo Panjang Village decreased drastically than the number of hotspots in the previous year. This proves that the existence of supporting factors in efforts to decrease the number of hotspots of forest and land fires that need to be known. The purpose of this research is to determine the main factors supporting the reduction of forest and land fires and to know the efforts made by related parties to reduce forest and land fires in Rimbo Panjang Village. The methods in this study using AHP (Analytical Hierarchy Process). The results of this research indicate that the factors supporting the decrease of forest and land fires at the criterion level are climatology (0.382) and technique (0.204). Furthermore, the main factors supporting the reduction of forest and land fires to the factor level are drilling well (0.295) and the presence and role of MPA ( 0.210). Efforts that have been made by related parties are drilling wells and canal blocking and coordination and cooperation by all parties in the control, monitoring and prevention of forest and land fires.

The community forests management of Styrax spp.becomes a culture and the source of life and social prestige of a family which is measured by the size of the Styraxspp. garden owned and has even become part of the life of the Sytraxspp. farmerin HumbangHasundutan, especially Simarigung Village. As time goes by, many Styraxspp. farmers are turning into horticultural farmers to sufficethe needs of farmers. The purpose of this research is to know the pattern of cultivation of Sytraxspp. plants, to know the contribution of Sytrax spp. plants to household income, and the factors causing the low income of Styrax spp. farmers in Simarigung Village. Sampling method were taken by simple random sampling. The study population was all the head of the family in the Village Simarigung as many as 225 families. The research sample is 20% 25 families of 125 families who manage Styrax spp. The results showed that the major contribution to the community forests of Styraxspp. about household income in the Village Simarigung around Rp. 10.810.000,00- Rp. 22.220.000,00/year and overall was 47.64% or Rp. 457.390.000.00/year. In research show that the management of Sytrax spp. is still traditional and monoculture.The low income of Styraxspp.due to old age and younger Styraxspp. that cannot be notched and lack of maintenance can reduce the quantity and quality of Styraxspp. resin production.

Lahan gambut di Provinsi Riau dapat dimanfaatkan dan dikelola di bidang pertanian dengan menerapkan sistem agroforestri, Salah satunya di Desa Dayun yang terletak di Kecamatan Dayun, Kabupaten Siak, Desa Lalang yang terletak di Kecamatan Sungai Apit, Kabupaten Siak, dan Desa Lalang Tanjung yang terletak di Kecamatan Tebing Tinggi Barat, Kabupaten Kepulauan Meranti. Faktor yang mendukung untuk menerapkan sistem agroforestri ialah sistem agroforestri berupa jenis produk yang dihasilkan yang sangat beragam dibanding, namun pengembangan agroforestri dipengaruhi oleh tanggapan masyarakat atau persepsi. Penelitian ini bertujuan untuk mengkaji persepsi masyarakat terhadap agroforestri pada lahan gambut di Provinsi Riau. Penelitian ini menggunakan metode snowball sampling dan pengumpulan data diperoleh melalui wawancara mendalam, observasi, dan studi dokumen. Data yang diperoleh dari hasil penelitian dianalisis dengan analisis deskriptif kualitatif. Hasil penelitian menunjukkan bahwa persepsi masyarakat terhadap agroforestri pada lahan gambut di Provinsi Riau dapat dilihat dari pola penanaman dan pemilihan jenis tanaman agroforestri yang sesuai pada lahan gambut. Masyarakat juga beranggapan bahwa agroforestri pada lahan gambut sudah memberikan kontribusi baik dari aspek sosial ekonomi maupun ekologi. Adanya beberapa tanggapan/persepsi mengenai pertimbangan dan persiapan dalam menerapkan agroforestri pada lahan gambut. Masyarakat juga memberikan tanggapan yang baik terhadap keberlanjutan agroforestri dan berharap agroforestri dapat diterapkan seterusnya.
