Abstract

Ghimbo Potai Banned Indigenous Forest is a prohibited forest that has a variety of wood species and non-timber forest products used by communities around the forest, along with the times, the use of non-timber forest products began to decline. The purpose of this study was to determine the types of non-timber forest products that are used by the community in Ghimbo Potai Banned Indigenous Forest and to determine the contribution of non-timber forest products to the community income around Ghimbo Potai Banned Indigenous Forest . This research was conducted with a qualitative descriptive method. The number of respondents was 170 respondents from Koto Tibun Village and Pulau Tinggi Village. The result show that Ghimbo Potai Banned Indigenous Forest still has non-timber forest products that can still be used such as chempedak (Artocarpus integer), petai (Parkia speciosa), long jack (Eurycomma longifolia), rattan (Calamus rotang), rambutan (Nephellium sp.), langsat (Lansium domesticum Corr), tampoi (Beccauera sp.), tempunik (Artocarpus rigidus), durian (Durio zibethinus), jelutong (Dyera costulata), terap (Artocarpus sp.), pulasan (Nephelium mutabile), dogfruit (Archidendron pauciflorum) and the eyebrowed thrush (Turdus obscurus). The contribution of non-timber forest products in Koto Tibun Village was Rp. 596,400,000.00 per year, so the percentage of non-timber forest product revenue to total income was 19.56% and Pulau Tinggi Village no longer takes or utilizes existing non-timber forest products in Ghimbo Potai Banned Indigenous Forest .

Abstract

The breeding of Timor deer at the University of Riau was successful due to the high adaptability of the Timor deer outside their habitat. Maintaining the success of Timor deer breeding at the University of Riau the need for direct observation of the environment and the availability of food at the likely location of Timor deer breeding to avoid undesirable things. This research was conducted to be a reference for better management of Timor Deer's breeding efforts at the University of Riau. The materials and tools used are moisture meters, measuring instruments, cameras, compasses, tape measures, ropes, pH meters and clinometers. The method of investigation used is the census method using the path system. The study area of 2.07 ha with the census method records the water conditions, the topography, the protection of the canopy, the vegetation, the temperature and the humidity, which were not previously known. For an investigation area of 2.07 ha, a plot of 20 m width and 5000 m length is needed by drawing a line of intersection for population indications observed in the prospective breeding area. The results showed that the physical location of the potential stag breeding at Riau University could very well be determined and developed as a breeding ground for Timor stags. Suitability of Timor-Deer habitat (Cervus timorensis) at potential breeding grounds of the University of Riau supports various forest types, shade trees, feed types, roofing stratification and plant vegetation for the Timor-Deer breed (Cervus timorensis). The availability of biotics in breeding candidates is considered appropriate for the survival of the Timor-deer.

Abstract

Mangrove forest have a diversity of potential benefits for human life, so they need to be maintained so that their utilization can be sustainable. The surrounding community must be the main actor in the management of mangrove forests so that the benefits can be felt directly by the community. This study aims to determine the level and form of community participation in the management of Mangrove Forests in Rawa Mekar Jaya Village, Sungai Apit District, Siak Regency. Data were collected through observation, closed interviews with 73 respondents, in-depth interviews, and documentation studies. Data were analyzed descriptively qualitatively and processed with percentage techniques. The results showed that 69.87% of respondents had a low level of participation in all stages of mangrove forest management because management tended to be exclusively carried out by the Rumah Alam Bakau Tourism Conscious Group. 71.23% of respondents has a low level of participation at the decision making stage, implementation stage, and evaluation stage. 72.60% of respondents has a low participation rate at the stage of enjoying the results. Respondents who participated highly at every stage of management were those who joined the Rumah Alam Bakau Tourism Conscious Group. Forms of community participation in the management of mangrove forests are contributions of ideas / thoughts, energy, skills, and goods (property).

Abstract

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.

Abstract

Soil macrofauna is a part of soil biodiversity that plays an important role in the improvement soil physical, chemical and biological properties. Fires that occur will affect the activity and presence of soil macrofauna which helps the decomposition process of organic materials such as providing better environmental facilities (Micro Habitat). This research aims to know species diversity and population density of soil macrofauna on burned and unburned land in The Rumbio Customary Forest. The research was carried out in The Rumbio Customary Forest and the Soil Laboratory Faculty of Agriculture University of Riau. The sampling of soil macrofauana was carried out on burned and unburned land in The Rumbio Customary Forest and also for measurement of soil physical-chemical factors. The research used the hand sorting method. This research showed that the population density of soil macrofauna on unburned land is higher if compared to burned land.
