    (2018-03-12) Budijono, Budijono; Hasbi, Muhammad; Purwanto, Eko; Harahap, Sampe
    Ceratophyllum demersum is a type of drowning macrophytics that plays a key role in freshwater ecosystem and is commonly used in phytoremediation of heavy metals in water. This preliminary study focused on assessing the ability of C. demersum in accumulating heavy metals (Pb and Zn) into their body tissues from heavy metals contained in the water of the Siak River. This plant is grown in natural condition (S. Siak) at different water depth (0,5,5,1 m) with aquatic plant floating raft. Measurement of water samples and water retrieval as well as entire plant tissue per depth for calculated heavy metals at different time intervals (6, 12, 18, 24, 30 days). The results show that the Siak River has been contaminated with Pb and Zn and the concentration of Pb> Zn in C. demersum with each Pb of 0 - 1m water depth is 12.641 mg / kg, 15.659 mg / kg and 16.604 mg / kg of initial concentration of 0.158 mg / kg. The average absorption rate and Pb accumulation per depth are 78.86%, 97.92% and 103.89%, respectively. It was concluded that phosemediation of heavy metal Pb in Siak River was effective with C. demersum up to a water depth of 1 m.

    KULTUR MIKROALGA Chlorella sp. DALAM MEDIA AIR GAMBUT YANG DIPERKAYA DENGAN NUTRIEN CAMPURAN LIMBAH CAIR ORGANIK
    (2019-11) Singal, Christina Lydia; Budijono, Budijono
    Microalgae have a big role in handle of water pollution control that able cultured by peat water media. Peat water has a low nutrient contain and should be riched by organic alternative nutrient came from slaughterhouse and tofu liquid waste. The liquid waste tofu industry is around 20 million m3/year while the slaughterhouse contributes about 30,000-52,500 liters/day. These liquid wastes contain high organic matter such as nitrate and phosphate and have not been utilized to the maximum that can be used if released directly into water bodies. The purpose of this research was to study the effect of tofu liquid mixture and slaughterhouse used as nutrients in the growth of Chlorella sp. on peat water media. This research was conducted in May 2019 at the Greenhouse of the Faculty of Fisheries and Maritime Major, University of Riau, that using 5 types of treatment with different levels of concentration. The operational volume of each experimental unit was 3 liters which was then added by Chlorella sp. a total of 75 ml (2.5%). The results of this research indicate the growth and abundance of Chlorella sp. about 7,415 x 109 cells/l in the handling of P3 (60%) and there was a decrease in the value of Nitrates from 0.342 mg/l to 0.110 mg/l and Phosphate values from 27.356 mg/l to 17.511 mg/l. Similarly, other water quality parameters such as dissolved oxygen with an increase from 3.50 to 4.10 mg/l,, pH increased 8 and temperature according to the optimal limit of 33oC which indicates good water quality. The Conclusions are tofu industry liquid waste and slaughterhouse can be used as nutrients needed by Chlorella sp. in its growth and to improve water quality for the better. Besides Chlorella sp. has a lot of potential and benefits in daily life.

    PEMANFAATAN HASIL FERMENTASI DARI CAMPURAN SISA PRODUKSI INDUSTRI TAHU DAN MINYAK KELAPA SAWIT TERHADAP PERTUMBUHAN Chlorella sp. PADA MEDIA AIR GAMBUT
    (2019-11) Fitra, Muhammad; Budijono, Budijono
    Tofu and palm oil industries produce a lot of residual production of high organic matter. With the addition of EM4, the residual production can be accelerated decomposition into a nutrient-rich material so that it can be utilized for the growth of Chlorella sp. This study aims to determine the benefits of fermented tofu industry residuals and palm oil for the growth of Chlorella sp. on peat water media conducted in March - October 2019 at the FPK Alga Research Center Laboratory of the University of Riau. Samples of the remaining tofu industry production were taken in Pekanbaru City and the Palm Oil Mill at PTPN V Tandun and peat water from the Kuala Terusan River in Pelalawan Regency. The number of treatments in this study were seven treatments consisting of P0 + (0% + 400 mL Dahril Solution 1), P0- (0%), P1 (40%), P2 (45%), P3 (50%), P4 (55 %), and P5 (60%), where the% value in each of these treatments is the result of the fermentation of the remaining production of the two industries in the operational volume of 3 L. Each treatment was added with 300 ml of Chlorella sp. with a culture period of 14 days. The parameters measured were abundance and biomass of algae, nitrates, phosphates, DO, CO2, chlorophyll-a, pH, temperature. The results showed the best media at P3 (50%) with an initial abundance of 785 x 106 cells / L to 12,812 x 109 cells / L and biomass 0.84 mg / L on the 8th day. Nitrate concentration from 11.76 mg / L decreased to 0.11 mg / L, phosphate from 39.82 mg / L to 0.43 mg / L. The DO value increased to 5.67 mg / L, CO2 decreased to 3.35 and the pH increased to 7. It was concluded that the fermented mixture of the remaining industrial production of tofu and palm oil could be used as a nutrient for the growth of Chlorella sp.

    PEMANFAATAN NUTRIEN DARI HASIL CAMPURAN SISA PRODUKSI RUMAH MAKAN DAN INDUSTRI TAHU UNTUK KULTUR Chlorella sp.
    (2019-11) Sihombing, Michael Halomoan; Budijono, Budijono
    Pressure on aquatic is now becoming heavier due to the contribution of residual production discharges. Restaurants or domestic and tofu industry is one of the biggest contributors. Restaurant wastewater is the most dominant because it occupies about 60-70% of water bodies, while tofu industry is capable of producing 15-20 m3 of waste to process 1 ton of soybeans into tofu. Both of these activities can produce large amounts of waste water and pollutants that contain nitrates and phosphate as nutrients for the growth of microalgae such as Chlorella sp. This study aims to look at the effect of a mixture of tofu and restaurant wastewater as a fermented nutrient that is easily absorbed for the growth of Chlorella sp. This type of microalgae has the ability to absorb carbon, produce oxygen, absorbent pollutants, natural food, etc. The study was conducted in May 2019 using 5 different mixtures of liquid waste and controls. Each unit had an operational volume of 3 liters, added about 75ml of pure Chlorella sp. seeds and cultured for 7 days. Research results show that the growth of Chlorella sp. increased from 1,008 x 109 cells/L to 7,461 x 109 cells/L in the temperature range of 30-40.6 oC with P5 (100%) treatment on the 5th day. The value of dissolved oxygen (DO) has increased from 2,67 mg/L to 5,50 mg/L. Chlorella sp. utilizing nitrate and phosphate so that it decreased from 8,1167 mg/L and 54,4137 mg/L to 0,128 mg/L and 14,508 mg/L. Peat media which has an acidic pH range of 4-5 has increased to 8-9. The discoloration of water which was originally yellowish to dark green, indicates that the nutrients from the waste mixture can be an alternative nutrient in increasing the abundance of microalgae especially Chlorella sp. in peat waters.

    PENINGKATAN KUALITAS AIR GAMBUT MENGGUNAKAN DOSIS CAMPURAN KAPUR TOHOR, TAWAS DAN PAC DALAM KEMASAN OSMOFILTER
    (2019-11) Liani, Rahma; Budijono, Budijono
    Most of the Bengkalis areas are peatlands which save a very large quantity of water, but the quality is low, so that its use is limited to fill clean water needs or to support fisheries activities. Many studies have shown alum coagulant and PAC (poly allumunium chloride) can improve the low quality of peat water, but the finding of the coagulant dose partially or in different mixtures that are highly dependent on the characteristics of peat and limited reported the coagulant is available in a practical package. The aims of this study is to determine the quality of peat water coming from the island of Bengkalis in the range of pH 2 - 6 with a dose of lime mixture of 0.5 gL- 1, alum 0.34 gL-1 and PAC 0.56 gL-1. The research was conducted in March-October 2019 at the FPK Waste Management Laboratory, Riau University, using the experimental method. The processed peat water was tested by bioindicator Chlorella sp. Water quality parameters observed were pH, color, organic matter, turbidity, temperature, CO2 and growth of Chlorella sp. The results have shown a mixture of lime 0.5 gL-1, alum 0.34 gL-1 and PAC 0.56 gL-1 could increase the conditioned pH from 2-6 to 6-9 and a decrease in color from 1441 TCU to 39.7-154.7 TCU, turbidity from 24.2 NTU to 1.72-4.08 NTU and organic matter from 520.2 mg / L to 23.6-28.7 mg / L and abundance of Chlorella sp. increased from 224,000-308,000 cells / ml to 1,296 x 106 -1,648 x 106 cells / L. It was concluded that the mixture of lime thor, alum and PAC was able to improve the quality of Bengkalis peat water with a pH of 2-6 and suitable to fill the needs of clean water and fisheries activities.
