    Fluctuation Of Chemical Properties For The Soil and Water Pond Podsolic Red Yellow On Ponds Soil Ages and CaCO3 Liming
    (2013-07-15) Putra, Edi; Syafriadiman
    This research was conducted from October to November 2012 at Environmental Quality Cultivation Laboratory Fisheries and Marine Science Faculty of Riau University. The purpose of this study was to determine the quality of the soil and water conditions are best based on age groupings podzolic red yellow pond bottom soil. Experimental method was used and complete random design (CRD) was applied. The treatments consist of pond ages ranging from 0-5 years old for O1; 6-10 years for O2; 11-15 years for O3; 16-20 years for O4. The results fluctuation chemical properties of the soil either at trial without liming and with liming show leaning enhancement improvement the soil quality with the age difference and enhancement content KBOT, soil Nitrate, and soil Phosphate increased with the use of lime CaCO3. The range of water quality parameters during the study classified as either, as if pH about 6 -7,3, and temperature about of 24-32 0C. Some water quality still relatively deficient as if DO about 2,1-3,67 ppm, water nitrate about of 0,014-0,063 ppm,and hardness about of 12,727-48,783 ppm.

    The research was conducted from April until June 2012 at Soil and Water Quality Management Laboratory Fisheries and Marine Science Faculty of Riau University. The aim of the reseeu-ch was to know effect of CaCOs lime to the pond bottom soil of chemical fertility and the water quality. The method used was experiment and randomized block designs with 1 factor is CaCOalime, with 5 level of treatments doses of CaCOslime from 0 g/m , 6.67 g/m^, 56.00 g/m^, 112.00 g/m^, and 168.00 g/m^, and 2 groups is new pond age (0- 4 years old) and old pond age (5-10 years old). The result indicated that the some doses of CaCOalime to increase in pH soil pond ageO-4 years and 5-10 years is 168.00 g/m^ (P4). These conditions resulted to increase inthe initial pHrange from5.0-5.8to6.7-7.1, C-organic about 0.75%, N-total of approximately 0. 07%, KPK approximately3.2 to 3.8me/100g, C/N ratioaroundlO.O to 11.1. Thewater quality improvementin bothage groupsoccurred frompH 5.7to 7.7, increase inturbidity, hardness, increase inthe dissolved oxygenat pond age5-10 years old andconcentration ofhitratein thepondage ofD-4 years old.

    Multiple Regression Water Quality Parameters Model for The Napoleon Fish (Cheilinus undulatus) Growth in The Sedanau Island Cages, West Bunguran District, Natuna Regency, Riau Island Province.
    (2013-07-18) Frengky; Syafriadiman; Pamukas,Niken Ayu
    The research was conducted from October until December 2012 in The Sedanau Island Cages, West Bunguran District, Natuna Regency, Riau Island Province. The aim of the research was to improve the regression equation of water quality parameters and the Napoleon fish (Cheilinus undulatus) growth. Water quality, was obtained from 5 stasions. Results shown that fishes were commonly reared for 3 months and total growth during the rearing period were, 24 - 25 g in 1st month, 26 - 28 g in 2nd month and 31- 32 g in 3rd month. While the quality in The Sedanau Islands was : temperature 29 - 310C, brightness 100 - 320 cm, current speed 0.16 - 2.20 m/s, pH 7-8, oxygen 4.35 - 9.86 mg/l, NH3-N 0.001 - 0.037 mg/l, Phytoplankton density 48107 - 54385 cells/ml, zooplankton density 11388 - 19345 cells/ml. Regression equation of fish growth and water quality parameters were as follow : temperature y = -0.708x + 49.34 R² = 0.017;r = 0.131, brightness y = 0.016x + 24.66 R² = 0.120; r = 0.378,current speed y = 2.962x + 26.34 R² = 0.426 ; r = 0.653, pH y = -2.016x + 43.21 R² = 0.092 ; r = 0.30, oxygen y = -0.915x + 34.71 R² = 0.137 ; r = 0.37, NH3-N y = -49.58x + 28.84 R² = 0.016 ; r = 0.13. Results shown that current speed and oxygen was made the strongly available with LPH the Napoleon fish as follow : current speed : 42% and Oxygen : 13.7%.

    PERBAIKAN PROSES PEMBELAJARAN MATA KULIAH BUDIDAYA MOLUSKA Dl PROGRAM STUDI BUDIDAYA PERAIRAN FAKULTAS PERIKANAN DAN ILMU KELAUTAN, UNIVERSITAS RIAU
    (2014-11-21) Syafriadiman; Ahmad, Yani; Rusliadi
    Projck porbaikan pwHcn pombojajaran mala kuliah Budidaya Moliuka ini bcrtujuan uiituk mcningkatkan pongetahuan dalam pomahaman dan ponalaran mahaniswa Icrhadap matcri-materi perkuliahan yang dibcrikan. Pcnggunaan metode konibinnsi ccramah, tanya jawap, diskusi, kcrja lapangan dan dcmonstrasi, melengkapi sarana perkuliahan (papan tulis dengan OHP/OHT, hand out, diktat, kaset vidio, teks book berbahasa Indonesia dan berbahasa Inggris), pemberian tugas-tugas kepada mahasiswa dan mcmvariasikan soal-soal yang diujikan, terbukti tclah dapat meningkatkan kualitas pembelajaran matakuliah Budidaya Moluska pada semester genap Tahun Ajaran 1999/2000. Prosentase nilai A dan B pada semester genap tersebut adalah mcningkat dibandingkan dengan semester-semester sebelumnya. Sebaliknya, prosentase nilai C dan D pada semester genap tersebut adalah lebih kecil bila dibandingkan dengan semester-semester sebelunmya. Jadi, dapat disimpulkan bahwa penggunaan metode dan sarana pembelajaran yang berbeda dapat meningkatkan prosentase nilai A dan B serta penunman nilai C dan D. Oleh karena itu, penggunaan metode pembelajaran yang dilakukan pada semester genap Taliun Ajaran 1999/2000 adalah dtsarankan untuk pembelajaran mata kuliah Budidaya Moluska atau mata kuliah yang lainnya, supaya kualitas pembelajaran lebih baik.

    (2013-07-16) Sirait, Ranny; Hasibuan,Saberina; Syafriadiman
    The research was conducted from January to March 2013 in a Laboratory Environment Quality cultivation, Fisheries and Marine Science Faculty of University of Riau. The purpose of this research is to know the basic podsolic red yellow soil quality a mixture of organic fertilizer quail droppings and inorganic fertilizers from Urea, SP36 and KCl and water quality. The method used in the experiment was Randomized Complete Design with 6 degrees of treatment with 3 replication. The treatment used in this experiment was (without treatment), proportion of 100% organic fertilizer (75,96 g): 0% inorganic fertilizers (0 g; 0 g; 0 g), proportion of 70% organic fertilizer (53,17 g): 30% inorganic fertilizers (0.25 g; 0.04 g; 0.14 g), proportion of 50% organic fertilizer (26,59 g): 50% inorganic fertilizers (4.16 g; g; 0,68 2.26 g, proportion of 30% organic fertilizer (7.98 g): 70% inorganic fertilizers (5,82 g; 0.95 g; 3.16 g), proportion 0% organic fertilizer (0 g): 100% inorganic fertilizers (8.25 g; g; 4,52 1.36 g). Result showed that the provision of organic and inorganic mixed with different dose effect on the quality of soil as soil pH, soil organic matter, cation exchange capacity and posphate. Treatment that can provide the best influence on the characteristics of the land base of the pond is the proportion of 50% organic fertilizer:50% inorganic fertilizers.

    (2016-04-12) Syafriadiman; Pamukas, Niken Ayu; Huri, Eryan
    Research of Toxicity of industrial palm oil waste water and sub lethal test to Oreochromis sp. has been conducted on February 1st to March 1st 2009 in Aquaculture Technology Laboratory, Fisheries and Marine Science Faculty University of Riau. Objective of this research is to determine the concentration of a test material or the level of an agent that produces a deleterious effect on Oreochromis sp. during a short-time exposure under controlled condition. In this study, static 96-h acute toxicity tests were carried out using Oreochromis sp. as test organisms. Probit analysis using the computer software EPA and graphical method were used to caculate the 96-h LC50 depending on data suitability. Results of the 96-h LC50 and Biological Savety Level of the industrial palm oil waste water were 126,06 ml/l and 1.26 ml/l respectively
