Abstract

This study was intended to evaluate the nutritional value of instant noodlesfortified with catfish flour. Instant noodles were prepared from a mixture of wheatflour (50%), sweat potato flour (10%), egg (15%), salt (0,7%), water (23%),cooking oil (0,3%) and Carboxy Methyl Cellulose (1%). The noodles wereprepared by fortifying the mixture with catfish flour at a level of 0%, 5%, 10%,and 15 % respectively. Instant noodles was evaluated for sensory quality andproximate composition (moisture, protein, carbohydrate, and fat). The resultshowed that instant noodles fortified with 15% of catfish flour has the bestsensory and proximate quality. Moisture, protein, carbohydrate, and fat for theinstant noodles was 3,88%, 36,67%, 21,00%, and 9,03% respectively.Keyword : Catfish flour, instant noodles, Pangasius hypophthalmus

Abstract

This research has been done on the Bakuok Lake in Aursati Village Tambang Subdistrict District Kampar in March - April 2014. This research aims to understand the vertical profile of phosphate in this reservoir. The research used survey method. The sample’s were taken from three station and vertically in three sampling point. The parameters of water quality measured were observed pH, dissolved oxygen (DO), brightness, temperature and depth. Sampling vertical based on transparency, namely at surface, 11/2 Secchi depth and in the bottom of lake. The result shown the concentration of phosphate at the surface: 0,01 mg/L – 0,03 mg/L; in the 11/2 Secchi depth; 0,04 mg/L – 0,09 mg/L; and the bottom of lake: 0,09 mg/L – 0,17 mg/L. The vertical profile of phosphate showed the concentration increased with the increment of depth. The water quality parameter were temperature 29,6oC – 30oC; transparancy 74,3 cm – 93,7 cm; depth: 208 cm – 332 cm; pH: 6 and dissolved oxygen (DO): 1,78 mg/L – 5,33 mg/L. The concentration of phosphate in Bakuok Lake showed the tropic status was mesotropic and all the water quality still support the aquatic organisms life.Keywords : Phosphate, the vertical profile, Bakuok Lake

Abstract

This study was intended to evaluated fat concentration of catfish surimi prepared by different washing methods. Catfish were teken from fish pond culture in Pekanbaru. The fish were filleted, ground and the mince was grouped into three parts which washed respectively in cold water without salt, cold water + 0,3% saltfor 30 minutes and without soaking. The fish then was pressed; and the surimi was evaluated for fat, protein, TVB, pH and yield. The result showed that the fat of surimi washed in cold water without salt has the best quality. Fat concentration for the surimi washed in cold water without salt, cold water + 0,3% salt and without washing was 5,138%, 5,794%, 6,454% respectively. Protein TVB, pH and yield for surimi washed in cold water without salt were 14,186%, 11,52 mgN/100g, 6,798 and 25,01% respectively; for surimi washed in cold water + 0,3% salt were 13,93%, 9,28 mgN/100g, 6,848 and 23,17% respectively; and for surimi without washed were 15,846%, 16,64 mgN/100g, 6,848 and 28,72% respectively.Keywords: Surimi, Fat, Reduction, Cold water, Salt

The study aims to understand morphological and meristical characteristics,relative growth and condition factor of Mystus nigriceps living in the Pinang LuarOxbow has been conducted on Januari to Maret 2014. The results There were 132fishes (23-184 mm TL and 2-40 gr) which collected and measured. There are sevencharacters that will be calculated meristic and 27 morphometric characters that willbe measured in this study. Meristical characteristics of fins were as follows D.I.7,P.II.10-22, V.10-12, A.8-9 C.16-23. Twenty seven morphological characteristicswere measured and to understand the growth pattern, each character length wascompared with Total Length (TL) and was reflected as percent of the TL. Therelative growth patterns of the morphological characteristic measured is thecharacteristic growing faster than that of the TL.. Lenght-weight relationship shownthat m. nigriceps male growing isometric and m. nigriceps female allometric positive(male b=2,968 and female 3,092).

Abstract

The research has been done on february 2014 in Sungai Alam Village, Bengkalis Subdistrict,Bengkalis Regency, Riau Province. A research aims to understand the Productionand Decomposition Rate of Mangrove Litter in Sungai Alam Village. There were 3 stationsand 3 plots in each station (station 1 in the mangrove conservation, station 2 in the goodmangrove forest and station 3 in the mangrove exploited wisely). In each plot, 1 net 1 x 1 m2were placed mangrove dominant. This net 2 meters above the mangrove forest floor. The bag(nets 20 cm x 10 cm) was filled with 10 grams litter and used for studying the litterdecomposition rate. The bag were placed in forest floor still be suffused of water. Sampel forlitter production, decomposition rate and water quality were taken once of 7 days (3 times).Results shown the highest litter production was ini St 2 (52,5 gr/m2/day) and thelowest was in the St 1 (25,151 gr/m2/day). Decomposition rate of the litter in each samplingpoints was relatively low in the 1st week and become faster in the 3st week. The highestdecomposition rate litter mangrove (lief, stick, flower or fruit) was in the St III, while thelowest was in the St 1.Keywords : Mangrove litter, litter decimposition rate, Sungai Alam, Riau

Abstract

The waste water originated from rubber factory contain high concentrationof organic matter. Direct disposal of these waste to waters may negative impactsto aquatic organisms. To reduce the risk, the waste should be treatment. Theseresearch conducted from Desember 2013 – February 2014. The study aims tounderstand the effectiveness of biofilter and aquatic plants reactors to reduceorganic pollutants in the waste water originated from the rubber factory and thenused these water as fish life media. The water quality measured were BOD5 andCOD, beside it measured survival rate of fishes in the aquarium. Sampling forwater quality and fish were conducted 3 times, once/ two weeks. The resultsshown effectiveness BOD5 range 82,6% – 87,8% and COD range 80,8% – 84,4%.But in the control (without biofilter and aquatic plants shown low effectiveness ofBOD5 and COD were 50,1 – 55,1% and 38,2 – 44,5% respectively. Survival rateof Pangasius hypopthalmus (80%), Oreochromis niloticus (76,67%), andCyprinus carpio (70%) and in the control, survival rate of Pangasiushypopthalmus (56,67%), Oreochromis niloticus (36,67%), and Cyprinus carpio(23,33%). Based on data obtained, it can be concluded that the biofilter andaquatic plant was effective to reduce BOD and COD content in the rubber factorywaste water.Keywords: Rubber waste water, Biofilter, Aquatic plants

Abstract

This study was conducted from September-December 2013 in the tofu factory which is located on Kubang Raya street, Tarai Bangun village, Kampar distric, Riau province. The purpose of this research is the aims is to know the decrease of nitrate and phosphate in tofu liquid waste. The research used anaerob and aerob reactor as treatmen and without media as control. Results of combination treatment anaerobic - aerobic reactor biofilter with Eichhornia crassipes (Mart) Solms) of media can reduce nitrate levels during the observation of the effectiveness reaches 40,0-74.2 % and phosphate can be dropped with 46,2-72.3% effectiveness. For other parameters also are in accordance with the quality standards that have been established, such as pH 7, temperature 28 0C, and DO of 3.76 mg / l. While the media processing unit without (control) can also reduce levels of nitrate and phosphate, but the effectiveness of processing lower when compared to the unit of media. Where the effectiveness of 15,1-21.8 % for nitrate and phosphate effectiveness decline to reach 16,1-26.6%. processed of tofu wastewater is feasible to use for live media Sepat rawa (Trichogaster trichopterus) and Nila (Oreochromis niloticus) except Pantau janggut (Esomus sp). This is evidenced by the survival of Sepat rawa reaches 86.67 %, Nila 70%, and Pantau janggut only reached 46.67 % during 2 weeks of testing.Keywords : Nitrates, Phosphates, waste water, biofilter, plastic bottle, Water hyacinth
