Abstract

ABSTRAK : Penelitian mengenai proses pengolahan limbah dari pabrik pengolahan ikan menggunakan trickling filter bertujuan untuk mengetahui pengaruh sumber mikroorganisme terhadap pembentukan biofilm serta pengaruh biofilm dan variasi sirkulasi terhadap efektivitas penurunan Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), minyak dan lemak dari limbah pengolahan ikan. Penelitian ini diawali dengan pembuatan biofilm dari pecahan genting sebagai media menggunakan air limbah pengolahan ikan dan air sungai sebagai sumber mikroorganisme. Setelah biofilm terbentuk, air limbah dipercikkan ke dalam bak yang berisi biofilm tersebut sebanyak 4 kali sirkulasi. BOD, COD, TSS, minyak dan lemak diukur pada masing-masing sirkulasi. Data dianalisis dengan menggunakan ANOVA dua arah untuk mengetahui pengaruh sumber mirkroorganisme dan variasi sirkulasi pada efektivitas sistem dalam menurunkan parameter pencemar. Sumber mikroorganisme dari limbah pengolahan ikan lebih efektif dibandingkan air sungai. Analisis menujukkan bahwa sirkulasi 4 lebih Efektif dalam menurunkan BOD, COD, TSS, minyak dan lemak dengan persentase secara berurutan adalah 87,50%; 59,57%; 91,85%; dan 88,56%.   ABSTRACT : The research on waste treatment process from fish processing plant by using trickling filter aims to determine the  influence of source of microorganisms on biofilm formation, and the effect of biofilm and the number of circulation on the decrease of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), oil and grease. This study started with the formation of biofilm on roof tiles as the media, using fish processing waste and river water as the sources of microbes. The liquid waste was then trickled through the biofilm and circulated for four times. Samples were collected at each circulation and were analysed for their BOD, COD, TSS, Oil and fat concentrations. Data were analysed using two way ANOVA to determine the effect of microbe sources and circulation numbers on the effectivity of the system in decreasing the pollutant parameters. It was evident that biofilm formed by the fish processing waste was more effective than that by river water. The analysis also suggested that 4 circulations lower the BOD, COD, TSS, oil and grease most effectively, with the percentages of 87,50%; 59,57%; 91,85%, and 88,56% respectively.

Abstract

This paper discusses the speciation and bioavailability of Cu and Zn in sediments of  Benoa Bay during which the sediments were sieved in wet and dry conditions. The objective of the study was to determine the concentrations of Cu and Zn in various geochemical forms, therefore the bioavalabilities of the metals could be determined. The determination of the total concentrations of Cu and Zn in the sediments were carried out by the application of extraction with the mixture of HCl and HNO3 (3:1). The speciations of the metals were accomplished with the sequential extraction procedure. The metals concentration measurements were  performed by Atomic Absorption Spectroscopy technique with the calibration curve method. It was found that the total Cu concentrations in sediment sieved in wet and dry conditions were  178.4144 mg/kg and 179.9797 mg/kg, respectively. The speciation results for Cu in sediment sieved in wet and dry conditions were as follow: freely, leachable and exchangeable (EFLE) fraction 0.79 and 0.49%, Fe / Mn-oxide fraction 67.75% and 58.71%; organic and sulfide fractions 24.34% and 34.71%,  while resistant fraction 2.89% and 2.82%. Therefore, the bioavalable and resistant fractions of Cu in wet sieved sediment were 92,88 % and 2.89%, respectively, while those of dried sieved were 93,92 % and 2,82%, respectively. The total Zn concentrations in sediment sieved in wet and dry conditions were  195.4015  mg/kg and 196.9482 mg/kg, respectively. The speciation results for Zn in sediment sieved in wet and dry conditions were as follow: EFLE fraction 18.83% and 17.40%, Fe / Mn-oxide fraction 35.86 and 37.65%; organic and sulfide fractions 17.16% and 31.09%,  while resistant fraction 5.76% and 4.09%. Therefore, the bioavalable and resistant fractions of Cu in wet sieved sediment were 71.85% and 5.70%, respectively, while those of dried sieved were 86.14% and 4.09%, respectively.

Abstract

The purpose of this study was to analyze the impact of tourism on the water quality of Lake Beratan based on BOD and COD parameters. This research method uses descriptive quantitative through environmental analysis. Lake Beratan water sampling was taken at 3 points, point 1 representing settlements and agriculture, point 2 representing the middle of the lake, and point 3 representing tourist areas. The data obtained was compared with the Class 1 Lake Water Quality Standards, Government Regulation Number 22 of 2021. The results showed that the BOD parameters still met the quality standards, so there were not too many organic pollutants in Lake Beratan. While the COD parameter exceeds the quality standard at all points. This shows that chemical pollutants originating from domestic activities around Lake Beratan such as agriculture using fertilizers and pesticides as well as tourism activities such as restaurants cause an increase in the COD value.
