Abstract

The research was conducted from December 2014 to January 2015 in the Laboratory of Water Quality Management Faculty of Fisheries and Marine Sciences, University of Riau Pekanbaru. The Objective of the research was to obtain an overview of COD and BOD value changes during the study on container or media life of fish Snakeskin Gourami (Trichogaster trichopterus Blkr) by given palm oil effluent with different doses. The method used in this study is an experimental, 5 treatments and 3 replications. The treatment used in this study is P0: no palm oil waste (control), P1: 1,286 ml/L P2 : 12,86 ml/L, P3 : 25,72 ml/L, P4 : 38,58 ml/L. The results showed that each containers research by palm oil waste with different doses decreased the velue COD and BOD. The highest the COD value of 185,33 mg/L with descreased to 80,67 mg/L, and the highest the BOD value of 101,33 mg/L descreased to 41,33 mg/L, and COD value of this research is the lowest in the control treatment that is the COD value of 9.67 mg/L, and the lowest is in the BOD value of the control that is equal to 5 mg/L.Key words : Changes, COD, BOD, Palm Oil Waste, Trichogaster trichopterus

Abstract

The aim of the research was to observe the consumer acceptance on the nugget made of catfish, snail and the combination of them. The raw material used as the main ingredients were that used were catfish, snail and combination of them at 5 level, 100% catfish (A1), 100% snail (A2), combination of 75 % catfish, and 25% snail (A3), 50% catfish and 50% snail (A4), and combintion of 25% catfish and 75 % snail (A5). The result showed that the highest consumer acceptance was produced by the treatment of A1 and A3. The best nugget produced was performed by the highest value of appearance, aroma, taste and texture. Based on the proximate composition, combination of 75% catfish and 25% snail (A3) produced nugget that contained 54,56% mouisture, 24,21% protein, 7,44% fat, and 4,48% ash.Keyword : : catfish, snail, nugget, consumer acceptance

Abstract

The research was conducted on 18th March to 23rd April 2015 atBrackishwater Aquaculture Development Center Jepara, Central of Java. The aimof this research is to determine the optimum percentage of feed in shrimpsenlargement activity. The Completely Randomized Design was applied in thisresearch with one factor and three replication. Treatment consist of feed pellets; P1(15% from biomass/day), P2 (25% from biomass/day), P3 (35% frombiomass/day), P4 (45% from biomass/day) and P5 (55% from biomass/day). Awhite shrimp (Litopenaeus vannamei) in length of 1,62 cm and body weight of0,05 g were reared in bucket (15 unit) with 120L capacity and density of 100tail/bucket. During experiment, the shrimps were fed on pellets four times daily.The results showed that the different percentage of feed gave effect for whiteshrimp growth. The best percentage of feed is 25% from biomass/day (P2) wasoptimum and gave the total weight with 0,934 g, total length 4,042 cm, specificgrowth rate 9,76%, and survival rate with 95,33%.Keywords : Litopenaeus vannamei, percentage of feed, growth rate

Abstract

Industrial rubber waste liquid is one of environmental issues that shall be handled as it is commonly discharged and potentially contaminate aquatic environment. This waste contain high organic material and it need to be processed. To understand the effectiveness of combination of plastic bottle biofilter media and emergent aquatic plant for remediation of that waste, a study has been conducted from December 2014 to March 2015. The waste was processed through plastic bottle biofilter media and then flown to phytoremediation unit that was completed with Limmnocharis flava and Echinodorus palaefoliu. The processed waste was then used to rear Cyprinus carpio, Pangasius pangasius and Oreochromis niloticus seeds, 20 fishes/ aquarium (15 L). Water samplings were conducted 3 times, once/ 2 weeks. The water was taken from 5 sampling points, they were in the inlet and in the outlets of the 1st biofilter, 1st phytoremediation, 2nd biofilter and 2ndphytoremediation units. Survival rate of the fish by the end of the research was noted. Results shown that the use of plastic bottle biofilter media and emergent plant phytoremediation process was effective to reduce the organic pollutant. Before being treated, the BOD and COD were 260 mg/L and 400 mg/L respectively. After being treated, the BOD reduced into 28 mg/L and the COD reduced into 60 mg/L. The effectiveness of the processor was 85% for the BOD and 80% for the COD. By the end of the research, survival rate of the fish was ranged from 90% - 100%. Based on data obtained, it can be concluded that the use of plastic bottle and emergent plant is effective for reducing organic materials in rubber industry waste water.Keywords : Plastic bottle, Limmnocharis flava, Echinodorus palaefoliu, Industrial rubber waste liquid

Abstract

Liquid wastes originated from tofu industries are rich in organic materials and it is potencial as basic materials for liquid fertilizer. To process the waste into liquid fertilizer, however, addition of EM4 and water hyacinth powder as N, P and K sources is needed. To understand the effectiveness of addition of water hyacinth powder in increasing the N, P and K content in the liquid waste, a study has been conducted on February to March 2015. Treatments applied were different concentration of water hyacinth powder. In 10 L of tofu liquid waste, there was 10 ml of EM4 and 24 gr (P1); 72 gr (P2); 120 gr (P3); 168 gr (P4) and 216 gr (P5) water hyacinth powder were added. The waste was fermented for 12 days and the N, P and K were analyzed. The quality of the fertilizer was tested by using it for fertilizing Azolla microphylla. Results shown that the highest N content was in the P3 (10,290.48 mg/l), the highest P content was in P5 (99.53 mg/l) and the highest K content was in P2 (12.59 mg/l). The N, P and K content in this fertilizer, however, is lower than the standard value SNI No.70/Permentan/SR 140/2011. Even though the growth of A. microphylla fertilized with the liquid fertilizer was slightly higher than the plant grown in the water, but it was significantly lower than that of the plant fertilized with chicken manure. This fact indicates that the quality of the liquid fertilizer made from tofu liquid waste was lower than the chicken manure fertilizer.Keyword: Tofu liquid waste, water hyacinth powde, Liquid Fertilizer, Azolla microphylla

Abstract

The objective of the research was to determine the effect the quality of freshwater mussel rendang with in varied weight, those were: weight 100 g (A1), 200 g (A2) and 300 g (A3). The method used was experiment and composed by using completely randomized design. The results showed that different weight of freshwater mussel meat affected to the quality of rendang produced. The highest quality of rendang was produced by the treatment of the using of 100 g mussel meat (A1) shown by the value of appearance 7.93%, scent 7.72%, sense 7.40% and texture 7.16%. The proximate composition consisted of moisture 54.03%, ash 3.14%, fat 14.85%, protein 23.23% and minerals that consisted of Ca 0.021 mg/g, K 0.019 mg/g, Na 0.035 mg/g, Fe 0.017 mg/g, heavy metals Cd 0.003 mg/g and Pb 0.008 mg/g.Keywords: Freshwater mussel, rendang, weight

Abstract

Periphyton is a group of aquatic microorganism that grew in the surface of natural substrates such as rock, wood, plants and aquatic animals. A research aims to understand the periphyton composition in the Salo River was conducted in April to May 2015. Sampling were conducted in 3 stations, they were in the upstream (St1), midstream (St 2), downstream (St 3), 4 times, once/ week. Results shown that there were 42 periphyton species present and they are belonged to 4 classes, namely Bacillariophyceae (28 species), Cyanophyceae (6 species), Chlorophyceae (7 species) and Dynophyceae (1 species). The abundance of periphyton in the upstream, midstream and downstream Salo River is significantly different, there were upstream (630 cell/cm2), midstream (1,499 cell/cm2), and downstream (4,545 cell/cm2) respectively. Periphyton abundance in the Salo River in general was around 630 – 4,545 cells /cm2.Keywords : Salo River, Periphyton, Composition
