Abstract

The objective of this study is to assess the influence of palm shell biofilter aplication in degrading organic pollutant in fermented soybean cake waste industryat aerobic system. This study was carried out in fermented soybean cake industry atTampan region, Pekanbaru. The total amount of wastewater that produced from onesmall industry fermented soybean cake is around 2 m3/day, and now is collected inwastewater drainage. Wastewater treatment of aerobic system. Basically thiswastewater treatment relies on bacteria in degrading pollutants. The use of palmshell is to increase specific surface of media for attaching bacteria. The systemconsist of one reactor that is made of 5 mm glass, and the volume reactor 140 liter.The reactor was equipped with one circulating pump and blower in the aerobic zone.It took 30 days for seeding micoorganism. The reactor were run in four differentresident time, namely 4 hours, 3 hours, 2 hours and 1 hour. The raw water used inthis experiment is waste water from tofu and fermented soybean cake industries thathave organic compound around 594.08 – 1276.64 mg/l. The water for physical andchemical analysis is sampled daily. It took from raw water and aerobic colum ofreactor. The results from 192 physical and chemical parameters from 24 watersamples showed that the palm shell biofilter gives a little influence to degradeorganic pollutant. The efficiency process in decreasing organic compund valuearound 6.47 – 16.48%, TSS 32.47 – 97.19%, TDS 7.89 – 19.25%, ammonia 0.66 –2.75%, total phosphate 1.76 – 5.13%, and nitrate 3.24 – 6.99%. The shorter retentiontime, the less removal efficiency of organic matter, TSS, TDS, ammonia, totalphosphate and nitrate.Key words : Biofilter, Biofilm, Wastewater Treatment, Aerobic Reactor, Organic Waste, Waste of Tofu and Fermented Soybean Cake Industry.

Abstract

A study aims to find out the domestication and triggering gonadal maturation techniques of Thynnicthys thynnoides obtained from Kampar River, Riau has beenconducted from June to August 2009. Fish samples were kept in 1 x 1 x 1 m cages,30 fishes/ cage. Fishes were fed on three types of food namely dried Tubifex, shrimppellet (without vitamin E addition) and shrimp pellet that is enriched with vitamin E(100 gram/ kg ). The food provided was 5% of total fish body weight/ day.Result shown that fish domestication can be conducted by keeping them in the cagesthat are placed in the area where the fish are captured. During the first week, fisheswere not fed and in the following weeks they were provided with the treated fed. Thebest result obtained in the fishes that are feed with shrimp pellet that is enrichedwith vitamin E. During the research period (8 weeks), 12 fishes were sampled and 5of them were in the 4th gonadal maturity level, their maturity indices was 15.603%,fecundity 19,516 eggs, egg diameter 1.07 mm and semen volume produced 0.945 ml.Key words : domestication, maturity indeces, fecundity egg diameter

Abstract

This research was conducted from July - August 2010 in Sungai BakauRegion, Sinaboi Sub Distric, Rokan Hilr Regency, Riau Province. This research aimsto identify spesies mangrove in Sungai Bakau region, lokan abundance and also tounderstand the relationship between mangrove density with abundance of bivalvia.The result showed that 9 species of mangrove were found: Avicennia marina,Avicennia alba, Rhizophora apiculata, R. mucronata, Bruguiera gymnorhyza, Soneratiaalba, S. coseolaris, and Nypa fruticans. Density of mangrove between 743 – 2.001trees/ha. In each stasion, there were 2 kinds of bivalvia such as Polymesoda expansa andPharus sp. The abundance of bivalvia 3.400 – 5.645 organism/m2. The highestabundance was obtained in the 3rd station (5.645 organism/m2), while the lowest was inthe 2nd station (3.400 organism/m2). To found out relation between mangrove densityand bivalvia abundance, the data were analized by using simple linier regretion.Theregression line test between mangrove density with abundance of bivalvia showed theequation Y=686,486 + 2,470 X with determine coefisien (R2) is 0,980.Keyword : mangrove, bivalvia, density, abundance, Sungai Bakau

Abstract

The aims of the research are : 1). to identify both the potential and the typesof utilizations of mangrove ecosystem carried out by the local society, 2). to analyzethe economic values of the mangrove ecosystem, and 3). to analyze the alternativesof the strategic utilization for mangrove ecosystem. The number of respondents is58 deriving from fishery household (RTP) and non RTP. The data were thenanalyzed by using consumer surplus, Total Economic Value (TEV) and MultiCriteria Analysis (MCA).The results show that biggest utility is the one of crabs that reaches Rp113,647,959 with the surplus consumer of Rp 27,780,612. The highest optimumprofit from arang bakau utilization amounts to Rp 360,732 for 11 (eleven)households, while the lowest profit is obtained from the utilization of prawn pondwith Rp 424,839. The biggest proportion is from the indirect utilization with apercentage of 85,58 % with a value of Rp 116,375,900,400 per year. Furthermore,the Total Economic Value of the mangrove forest ecosystem in East Bintan Districtcovering 2 ha for ponds, 1100 ha for HPHH licency and 3354,29 ha of mangroveforest amounts to Rp 135,977,965,849 per year. The utiliation alternatives put aspriorities, based on the balance between indicators for both efficiency criteria andecology criteria, between the efficience and equity criteria in the level oef interestrate 0f 10 % are as follows : firstly, utilization alternativ III (100 % mangroveforest), secondly, utilization alternative II (1100 ha mangrove forest by licencyHPHH and 33356,29 ha mangrove forest. Nevertheless, the utilization alternativ Ican not be given as choices in this management because utilization of prawn pondnot efficient.

Abstract

The objective of this study is to assess the influence of zeolit biofilteraplication in degrading organic pollutant in waste of tofu industry at combinationanaerobic-aerobic system. This study was carried out in tofu industry at Tampanregion, Pekanbaru. The total amount of wastewater that produced from one smalltofu industry is around 15-20 m3/day, and now is collected in wastewater drainage.Basically this wastewater treatment relies on bacteria in degrading pollutants. Theuse of zeolit is to increase specific surface of media for attaching bacteria. Thesystem consist of one reactor that is made of 5 mm glass, and the volume reactor 140liters. The reactor was equipped with one circulating pump and blower in the aerobiczone. It took 3 weeks for seeding micoorganism.The raw water used in this experiment is waste water from tofu industriesthat have organic compound around 1554 - 2539 mg/l. The water for physical andchemical analysis is sampled daily. It took from raw water and anaerobic-aerobiccolum of reactor. The results showed that the zeolit biofilter gives a big influence todegrade organic pollutant. The efectivity process in decreasing organic compundvalue ± 90% better than non zeolit biofilter.
