Abstract

Tofu industries are food industries which use a lot of water, both for operational system and as a basic material for production.Tofu industries produce liquid sewage which contains high organic subtances. Liquid sewage of tofu industries is one of the sources ofcontaminants, so that it is needed to have an appropriate waste processing. In order to overcome liquid sewage problem, a wasteprocessing is to reduce and eliminate dangerous materials and pathogenic microorganisms. Biological treatment is the commonest way inhandling the liquid waste from food industries. One of the biological processing that can reduce the contaminants content in liquidindustrial sewage is activated sludge. This activated sludge can also metabolize and break up the contaminants in the sewage and thisprocessing uses sludge.This research was carried out in order to know the growth rate of microbe biomass in activated sludge from 3 types of sludgetaken from the ditches of the tofu industries, the sludge taken from Pesanggaran Slaughterhouse and the sludge taken from Badung Riverwhich were composed into 4 compositions and then were seeded, than tested to get 4 sludge composition in order to reduce COD in tofuindustrial sewage. The parameters used were physical and chemical views. This research was done by measuring the changes in VSSvalue of the four sludge compositions which were seeded and the COD of the four tested sludge compositions.This research used factorial Randomized Completed sampling that consisting of 2 factors and three repetitions, that is the firstfactor was composition sludge and the second one ws incubation period and then were analyzed by using descriptive comprative analysisand uni –variant analysis.The result of this research shown that the best sludge composition used as activated sludge was the sludge composition takenfrom the ditches of tofu industries was 50 %, the sludge taken from Pesanggaran Slaughterhouse was 25% and the sludge taken fromBadung River was 25 % with had VSS of micobe biomass growth of 2265 mg/L and was able to reduce COD of tofu industrial liquidsewage up to 46.645 mg/L.

Abstract

This study was conducted at the Village of Delodbrawah, Jembrana Regency, Bali. It was aimed to know the managementpattern available at the Village of Delodbrawah, the effect of maintenance to the water quality of shrimp pond and river, vegetationcondition and river biota. The study was conducted for approximately 3 months in each pond starting from January up to May 2007.Shrimp ponds found in the Village of Delodbrawah use intensive and semi intensive management with open system where thechange its water maximaly from well and river. Semi intensive pattern used vitamin C as a mixture of food and the intensive one usedgarlic (Allium sativum L) as antibiotic. The use of natural antibiotics can increase the age of the shrimps up to 96 days before it washarvested. While the one using other probiotics, the age of the shrimps was 88 – 90 days shorter after it was harvested.The data of water quality showed that pond 1 that used intensive system had more stable water quality parameter and supportthe culture compared with other blocks. At the end of the culture of PO4 and NO2 tends to increase blooming plankton such asChlorella sp, Oscillatoria sp, Cyclotella sp. But it did not affect the quality of river water which was still under the threshold ofstandard quality of water class III Government Regulation of the Republic of Indonesia Number 82 of 2001 concerning theManagement of Water Quality and Water Pollution Control.Vegetation around the shrimp ponds were dominated by Nipah (Nypa fruticans Wurm) in the location nearing the river estuary.From the production data pond 1 had the best production, related to the nipah functioning as bioremediator of surrounding waters.The other location is near palawija plants. The most prominent river biota is kijing (Bivalvia) which looked bigger and many innumbers in the location where there are two disposal channels, pond disposal and agricultural channel that transports higher organicsubstance to be disposed to the river. Affectiveness of the intensive pond management optimally produces the oldest age of 96 days, the harvest of 3,964 – 4,271kg/1500 m2, Survival Rate (SR) of 98% and Feed Convertion Ratio (FCR) of 1,32

Abstract

Ayung river is one of the longest rivers in Bali. The upstream of the river is in regency of Bangli, Badung, Buleleng, Tabananand downstream is located in Padang Galak beach, East Denpasar Sub-regency. As the sample of the study, the water of the river wastaken from the stream entering the city of Denpasar. The sample was taken in five different points and for each point was taken twice. Thefirst was taken at 5 p.m, and the second was at 6 a.m. This study aims at finding out the rate of radioactive content of Ayung river water inthe city of Denpasar.The water sample was analyzed in Radiometry Analysis Group of Radiation Physics and environmental research centre andNuclear Technique Development, Jalan Taman Sari 71 Bandung – 40132. The process of counting was conducted in this place in order toknow the rate of the element activities and then identification of elements contens in the sample. The result of the counting and identifyingwas compered with standard grade of radioactivity in the area.The element of identification result and the amount of activity rate found showed that the element were natural radioactiveelements, the content: 40K (Kalium-40), 234Th (Thorium-234), 233Th (Thorium-233), 228Ac (Actinium-288), 114mIn (Indium-114m). Thehighest activity of radioactive elements in each sample point: in E2 point content element 40K with the activity 2.08 Bq/lt, in point A1 234Thwith the activity 16.34 Bq/lt, in point E1 containts 233Th with activity 598.29 Bq/lt, in point E1 and E2 contain 228Ac with the activity939.63 Bq/lt. The height of activity value of the counting and identifying elements was still under the rate of the highest level.The result of the study showed that radioactive elements 40K had the tendency of increasing radioactivity. The same thinghappened to 233Th at the peak of energi 185.00 keV. The content of its radioactive tends to exist in each point of sample point and theactivity tends to increase. Though the rate of radioactivity content was still under the highest permitted level (1x104 Bq/lt for 40K and7x102 for 233Th) bu the case needs to be watched out that the dangerus grade pollution would take place.
