    This research was conducted in 2013, in the waters of Lake Bandar Kayangan Samar Valley subdistrict Rumbai Pesisir city of Pekanbaru Riau Province. This study aims to analyze the extent of the tolerance of the quality of Lake Kayangan waters to fish farming (KJA) compared to the Standard Quality of PP No.82 of 2001 and analyze people activities around Bandar Kayangan Lake which led to the polluted waters as a result of daily activities. The method used is an experimental method by observing and measuring sample directly on rearing cages measure 1x1x1 m. Patin fries were stocked at the age of two weeks with the number ( 50 fries ) and 3 months time of rearing. Three units of cages were placed at each station that has been determined and Rumbai Freshwater Cultured Installation pond as control. Data were analyzed descriptively and statistically, the descriptive analysis performed on physical and chemical parameters of water based on PP No. 82 year 2001 and was associated with the growth and survival of Patin fry. Statistical analysis is using Analysis of Variance ( ANOVA ) and completely randomized design ( CRD ) with treatment of 3 times repetition. Growth and survival of Patin fry on each station were quite well where the average growth of absolute weight between 35.43-36.20 grams, the average growth rate of daily weight between 5.602-5.782%, the average of absolute growth inlength between13,61-14.10 cm, the average of daily growth in length between 2.285 - 2.321% and the survival rate between56-79%. The waters of Lake Bandar Kayangan is a waters that are so important for the life of people around Lake Bandar Kayangan especially for fish farming in Keramba Floating Net (KJA). The fish are nila fish, mas and gurami. From the results of interviews of researchers to the community around Lake Bandar Kayangan only certain types of fish are able to survive, this is due to the quality of water at Lake Bandar Kayangan can not be tolerated by other fish. But when the researchers tested the catfish seeds, the catfish still survive.

    Kayu Kelapa Sawit Peremajaan Kebun Sebagai Core Plywood Dan Penyimpan Karbon Di Provinsi Riau
    (2018-04-03) Siswoko, Endro; Mulyadi, Aras; Thamrin, Thamrin; Bahruddin, Bahruddin
    In 2016, the total area of oil palm plantation in Riau Province was 2,430,508 hectares. The treatment of oil palm waste from replanting activities via burning and decomposing may increases the amount carbon emission in the atmosphere which would cause global warming. This research aims to determine environment-friendly oil palm plantation management strategies, in particular oil palm trunks waste utilization as alternative staple source of making plywood core and carbon sequestration. This research took place at PT. Asia Forestama Raya’s (PT. AFR) factory in Pekanbaru, Riau Province. The data of this research was taken from 25 years-old replanted Tandum plantation owned by PT. Perkebunan Nusantara V Ltd. (state-owned) in Riau Province. Ninety one oil palm trunks were used for plywood core making test material. Based on technical aspect assessment (mechanical/physics), only 4 mm (three ply) plywood that passed all of the tests: adhesion shear strength, bonding strength, delamination, and moisture content. Oil palm tree has 223.68 kg C/trunk carbon biomass on average, or 28.63 ton C/ha. Carbon sink on core plywood was 53.68 kgC/trunk or 6.87 tonC/ha. Carbon dioxide stock -196.82 kgCO2/trunk, or -25.19 tonCO2/ha. The result of this research shows that oil palm trunks waste which was the biggest waste of replanting activities, could be used as an alternative timber/base source for plywood core that fulfills technical and also environmental aspects as carbon sequestration.
