Abstract

The study aimed to observe the effect of different kind of raw materials of liquid smoke on the quality of smoke flavored catfish (Cryptopterus bichircis). The experimental was designed as completely randomized design (CRD). The treatment was soaking catfish into different kind of solution of liquid smoke, namely liquid smoke pyrolyzed from rice husk (A1), oil palm midrib (A2), and coconut shell (A3). The catfish were soaked into the liquid smoke at a concentration of 6% for 60 minutes. Parameters to evaluate the quality of smoke flavored catfish produced were the sensory value of appearance; smell; texture; and taste, proximate composition, the content of total phenol, total acid, and pH values. The results showed that the different kind of smoke source was indicating significant effect on aroma, but not on appearance, flavor, and texture of the smoke flavored catfish. The chemical characteristics were significantly affected on the pH value and the content of total phenols, but not significantly affected on water content and the content of total acid. Based on the results of the study concluded that the best treatment was the using of the raw material of liquid smoke coconut shell (A3) which have the characteristics of smoked fish with 7.00, flavor at 7.61, texture at 6.71, and aroma at 7.29 and containing a total phenol of 5.28 ppm and pH. 4.63.Keywords: catfish smoked flavor, coconut shell, palm fronds and rice husks.

Abstract

 Abstrak                The research was conducted in March 2017 located at Maninjau Lake, Tanjung Raya Sub-District, Agam Regency, West Sumatera Province. This study  aims to determine the development trend of fish floating cages business and tourism development in Maninjau Lake and to know what objects are affected by fish floating cages business in Maninjau Lake. The method used in this study is survey method, where the determination of respondents to visitors and businessman using accidental sampling method.               The result of this research have showed that the relationship between fish floating cages business trend with development of tourism is when fish floating cage began to increase every year showed a trend that increased significantly and otherwise tourism development in Maninjau Lake showed a declining trend. Tourism objects that are effected by fish floating cages business has an influence on income both before and after the development of fish floating cages. afforts that have been made by the govemment in the development of tourism in Maninjau Lake after the development of fish floating cages is to optimize the reduction the number of fish floating cages plots and continue to seek the formation of environmentally friendly fish floating cages. Keywords :  Maninjau Lake, Fish floating cages, Tourism

Abstract

The peat water has low pH and it can be improved by adding bentonite and lime. The use of lime, however, produced relatively large amount of sediment. To understand the effectiveness of combined bentonite and lime in osmofilter paper package to increase the pH, a study has been conducted on May- July 2016. Combination of 1,7 g bentonite and 1,7 g lime were wrapped using osmofilter paper and were immersed in 2 L of different pH (2,3,4,5 and 6) peat water. After being kept for 45 minutes, the water quality was checked. Results shown that the package of bentonite and lime was effective to improve the pH. In all treatments, the pH increased, ranged from 7 to 9, but the treated water has relatively high colour and organic matter solid.   The treated water was use to rear Cyprinus carpio seedlings. By the 4th day, the survival rate of these fish was 90%. Based  on data obtained, it can be concluded that the use of combined bentonite, lime and osmofilter paper is effective to improve the quality of peat water, but is may not effective in reducing the colour and organic matter. Keyword : Peat Water, Osmofilter paper, Bentonit and Lime

Abstract

 AbstractLubuk Siam lake is an oxbow lake that is located in the Siak Hulu sub-district, Kampar district. There were several human activities around the Lubuk Siam Lake such as agriculture and palm plantation. This study aims to understand zooplankton vertical distribution in that lake and it was conducted in February to March 2017. There were 3 stations, namely Station 1 (inlet area), Station 2 (fish cage area), and Station 3 (outlet area). In each station, there were 3 sampling points: at the surface, 2 secchi depth (126 cm) and 3 secchi depth (189 cm). Water samples were taken once/week for 3 weeks periode. Water quality parameters measured were: temperature, transparency, pH, nitrate, dissolved oxygen and free CO2 . Result shown that total abundance of zooplankton in station I: 945-1680 ind/L, Station II: 1365-2190 ind/L, and Station III: 1.230-2.085 ind/L. Water quality parameters measured were as follow : transparency 63 - 69 cm,  temperature  27.5 – 31.10C, pH 6.83 – 7.27, dissolved oxygen 4.0984 – 7.8399 mg/L, free CO2 5.296 – 15.981 mg/L, and nitrate 0.0694 – 0.1688 mg/L.Keywords: Lake, Lubuk Siam, Zooplankton

Abstract

This research was conducted in April 2017 which is located in Maninjau Lake Jorong Galapung Nagari Tanjung Sani, Tanjung Raya District, Agam Regency, West Sumatera Province. The purpose of this research is to know the characteristics of fish farmers, to know adaptation strategy conducted by fish farmers and to know the relationship of characteristics with fish farming strategy. The method used in this research is survey method. Respondent in this research is household of fish farmer counted 48 people.Based on the results of this study, it can be concluded that the characteristics of cultivators in terms of age belong to the old category (> 50 years), the characteristics of education are quite good, the characteristics of family dependents are small and the characteristics of the experience of cultivation are low. The adaptation strategies undertaken by the farmers are adaptation strategies for diversification of economic activities, mobilization of household members, utilizing social networks and work migration. Having seen the relationship between the characteristics of cultivators with adaptation strategies of fish farmers known age factor does not prevent respondents to keep looking for alternative jobs. On the characteristics of education, the strategies undertaken by respondents are not varied. The number of dependent respondents who on average in the small category did not make the respondent perform various adaptation strategies. While the experience long enough to be a cultivator does not prevent the cultivators to seek strategies outside cultivation.Keywords: Strategy, Adaptation, Lake Maninjau, Tubo Balerang
