Abstract

Sumatran Tiger is the one and only tiger’s species which is still survive by Indonesia after Bali Harimau and Java Harimau which is have become extinct already.The conversion of Forest become other landsuch asHTI(Industrial Plantation Forest) andpalm oilplantationsattend effect ofconflictbetweenhumansandtigers. The dataof this studyis expected tobe areference forconflictmitigation. This observation used by using transectmethod in 5 m width. The observation observe toward the sign ofthe existence oftigersandtheir animalspeciesin form oftrail, dirt, scratches, the rest of theanimal. Every existence of the tiger there will be a vegetation analysis by making plot. The Result found that there is existence of tiger at 3 transect and 3 segment of secondary forest, 3 transect and 6 segment at HTI. Meanwhile, there is no founding of tiger existence at palm oil. The effect transforming of conversion becoming palm oil is there is no existence of the tiger itself, it because of the high of human’s activity.

Abstract

The mangrove forest is plants that live in the mouth of the river and were able to survive in the tide. The area has a mangrove ecosystem in Bengkalis is Teluk Pambang Village and need to be developed into the ecotourism area. Ecotourism development goal is to protect the existing potentials in the mangrove forests and became one of the alternative sources in raising funds for conservation activities. This research purpose to identify the ecotourism potential of mangrove forest in Teluk Pambang Village, Bantan District Bengkalis Regency, to knowing the efforts and forms of conservation for the development of ecotourism and  to knowing the correlation of ecotourism potential as a supporting mangrove forest conservation. The method that used in analyzing the potential of ecotourism is based on the analysis of mangrove vegetation that expressed in the formula English et al. (1997) to obtain density and the importance of community structure of mangrove conservation, efforts and  forms was processed using a Likert Scale and the relation of potential ecotourism as a supporting mangrove forest data was processed by descriptive. The results of this research indicate that the ecotourism potential of mangrove forest in the Teluk Pambang Village, consists of very density  mangrove forest. Station I had a density of 2,967 ind/ha, station II has a density of 5,778 ind/ha and Station III has a density of 4,688 ind/ha, vegetation and wildlife are varieties and landscape of ecotourism still nature. Efforts and forms of conservation were managed by the Manage Group of Mangrove (KPM) Belukap, habits and knowledges of local communities (local wisdom) in Teluk Pambang Village and participation of respondents to the conservation efforts.

As a supporting tool that provides useful information for various purposes, booth in terms of education, social, economicand ecology. It is necessary to support the complete data by conducting research on the animals in the Arboretum of Riau University, especially mammals, to find out the large index of diversity and richness of mammals species contained in Arboretum of Riau University. This Research held on November 2016 until January 2017. Method used for this research is a line transectsmethod and trap.On research location obtained result isthere 9 of mammals from 6 family founded with 63 individual that founded. The index of species diversity in both dry line (1,93) and wet line (1,73) was moderate. Richness index varieties dry line  (1,97) wet line(1,80)  is low.Most of mammals on Arboretum of Riau University are animals living on forest floor  (teresterial), small flying mammals are met for while research only bats  and kind of living animals on canopy area crown and the middle of the canopy crown (arboreal).  Keywords: Mammals, Diversity, Arboretum

Abstract

This research aimed to investigate the best soaking time for areca seed in young coconut water to improve its germination. This research was carried out in Jalan Limbungan, Limbungan village Rumbai district, Pekanbaru city. This research started from early March to end of May 2005. The method esed in this research was non factorial of completely randomized design with 3 replications. Parameters in this research were the time germination, germination ability, speed of germination, plumulae length, root length, and dry weight of seed. The seed soaking treatments significantly affected all germination parameters except the root length and the best treatment for araca seed is A4 (24 hours of soaking).

Abstract

Intensive agricultural practices in the upper land of the Indragiri river bring about problem to  oxbow-lakes spreading out along in the middle and downstream of the river. Danau Sungai Sorik (DSL) typically included to oxbow-lake, situated in the middle part of Indragiri River, one of four big river in Riau Province, Sumatera. Since the catchment area of the lake were totally urban, accordingly the dynamic equilibrium of lake ecosystem were shifted. The lakes were reportedly degraded in terms of hydrological regime, high sedimentation, fully vegetated and low biological diversity. The local government has repeatedly normalized the depth of the lake in related to development of water attraction, restocking of invading species of fish, cage culture and rice field along the edge of the lake. The present papers aimed at characterizing and assessment of physicochemical and biological properties of the water. Further, potential threats on the sustainability of the lake were assessed. Based on chemical properties of water including BOD5, phosphate and Nitrate range were of (3.26-7.43), (0.11-0.13) and (0.229-0.433) m/L, respectively, were categorized into un-equilibrium or slightly polluted. The water transparency appeared low (25-29) cm, the pH of 6.0-6.5) and temperature of 31-32 0C. Apparently, the diversity index (H), dominancy index and similarity index of phytoplankton ranged from (0.9110-1.2211), (0.3201-0.6136) and (0.3939-0.6290, respectively. It suggested slightly dominated by certain species
