An experiment on the immunization of Jambal Siam ( Pangasius hypophthalmus) withIchthyophthirius multifiliis vaccine was conducted in the Laboratorium of Parasitic and Fish Diseases,Faculty Fisheries and Marine Science of Riau University, and Laboratorium of Fish Health of FacultyFisheries and Marine Science, IPB. The objective of the study was to enhance immune system of the fishfry on the ichthyophthiriasis diseases. The vaccine was prepared by prolonged treatment of theron in waterbath of 47°C for 30 minutes. The vaccine was administrated to fish by immersion in aquaria. A completelyrandomized design (CRD) in factorial pattern (3 X 3 X 3) was carried out with dose and time as factors.Doses of treatment and time of immersion were of 1 ml/L, 2 ml/L and 3 ml/L as well as 15, 30 and 45minutes of treatment time respectively. To evaluate the effectiveness of vaccine in fish, a challenge test tofish was done at day 15 with theron 90.000 cell/ aquaria until rearing day 25 after vaccination. It revealedthat the best performance (p<0.5) were of dose 3 ml/L and time treatment of 15 minutes in that survivalrate of fish was 100% followed by dose 3 ml/L with time 45 minutes (63,3%). The total erythrocyte count,hematocrit level and hemoglobin of tested fish were fluctuated. The water quality were recorded including;dissolved oxygen range from 3,74 - 4,98 ppm; temperature 25 - 30°C and acidity of 4 - 6, quality were ofnormal range for fish. The optimal vaccine dose is 3 ml/l with 15 minute immersion.

Abstract

Human activities have had an impact on global warming due to greenhouse gas emissions. Greenhouse gas emissions resulting from industrial activities, transportation and human activities that use fossil energy sources. The purpose of this research is to analyze the increase of air temperature using CO2 and CH4 gas concentration data from 2010-2016, to know the effect of greenhouse gases on the increase of air temperature, and to analyze the most influential factors in increasing air temperature in Pekanbaru and Padang City. The research method used is survey method with assessment and processing of secondary data. The research results found that greenhouse gases in particular the concentration of CO2 gas affect the temperature rise in Pekanbaru and Padang City. The increase of air temperature in Pekanbaru City is 0.52 °C up to 0.61 °C higher than the temperature rise in Padang City 0,51 °C up to 0.60 °C. The correlation of CO2 gas concentration with temperature rise in Pekanbaru City influenced the increase of air temperature by 10.2%. Factors that affect the most increase in air temperature in Pekanbaru City is the number of vehicles and the number of hotspots whereas in the city of Padang temperature rise is influenced by the number of vehicles and the number of industries. Government policies are required in mitigation efforts to reduce the impact of increased greenhouse gas concentrations by tree planting, peatland management and zero burning land clearing
