Abstract

Emission of methane and carbon dioxide gas in the process of processing oil palm liquid waste PurposeThe purpose of this study was to know, calculate and evaluate the concentration of methane gas and carbon dioxide produced in each wastewater treatment plant (WWTP) pond.MethodThis research was a qualitative research, using case study design and explanatory approach. The object of this research was the emission of methane gas and carbon dioxide emitted from 12 WWTP ponds.ResultsThe highest COD and BOD decrement occurred in pond 4 of 39% COD and 61.2% BOD. The highest total methane gas emission was 1.49 x 109 kg hours-1 (1.49 x 106 tons hour-1) occurring in the morning, while the highest total carbon dioxide emission was 2.59 x 109 kg per hour (2.59 x 106 ton hour-1). ConclusionThe concentrations of methane and carbon dioxide gas produced by each WWTP pool varied greatly depending on temperature, residence time and the amount of mud. Methane gas emissions and carbon dioxide emissions occurred in each WWTP pool with the highest methane gas emission value occurring in pond 3 in the afternoon at 356,64 x 106 mg m-2minute-1 and the highest carbon dioxide emissions occur in pond 3 in the afternoon at 402.145 x 106 mg m-2minute-1. The decrease of COD value in whole anaerobic pool was 52,1% and the decrease of COD value in aerobic pool was 27,2%.

Abstract

Analysis of health risk due to lead (Pb) exposure in marine biota on the community around Kendari BayPurpose: To understand the risk level of health problem because of the lead exposure found on fish and shellfish that was consumed by community around Kendari bay.Methods: This study was an analytical observational through a cross sectional study design by combining Environmental Health Risk Analysis (ARKL) and Environmental Health Epidemiology (EKL) approaches. Population around Kendari bay was taken using proportional sampling criteria. The marine biotas in this study were 30 fish samples of 3 kind of most consumed fish and shellfish from 6 fishponds in Kendari bay. Measurement of lead content on it was made by Atomic Absorption Spectrometry (AAS).Results: The results of the study shows the lead content on fish and shellfish were 0,0027-0,0095 mg/kg and 0,1026-0,1097 mg/kg respectively while intake rapidity of fish and shellfish 0,0051 mg/kg/day and 0,016 mg/kg/day respectively. Health risk level of consuming contaminated fish was 1.29 while the contaminated shellfish was 4.03.Conclusions: The community around Kendari Bay has a risk of health problems (RQ> 1) due to lead exposure, therefore it needs to be controlled.

Abstract

Evaluating the use of anaerobic-aerobic biofilter to increase the quality of hospital wastewater Purpose: This study aimed to evaluate the anaerobe-aerobic biofilter systems effectiveness to treating parameters that are affected by the existing units. Methods: This study was conducted with quasi-experimental pretest-posttest approach. Sampling was done in peak hour, intermediate, and minimum wastewater discharge The data analysis used a comparison of quality standards and used the effectiveness level of wastewater treatment through the established formula. Results: The results showed that anaerobic-aerobic biofilter was highly effective in treating total coliform at peak discharge (99.9%), intermediate discharge (83.80%), minimum discharge (99.9%) and effective in processing COD parameters 70.13% at intermediate, and 74.60% minimum discharge. The results also showed anaerobic-aerobic biofilter was quite effective in treating BOD (54.59%) and TSS (50%) and less effective phosphate (40.7%). Data analysis showed that the results of wastewater treatment of provincial hospital in West Nusa Tenggara have met the established quality standards. Conclusion: An anaerobic-aerobic biofilter is effective to increase hospital wastewater to reduce environmental pollution. The impact of this processing will reduce environmental pollution.AbstrakTujuan: Penelitian bertujuan untuk mengevaluasi penggunaan sistem biofilter anaerob-aerob terkait efektivitas dalam mengolah parameter yang dipengaruhi oleh unit yang ada. Metode: Penelitian ini merupakan penelitian quasi experimental dengan menggunakan pendekatan pre-test dan post-test. Pengambilan sampel dilakukan pada saat debit puncak, menengah, dan minimum air limbah. Analisis data menggunakan perbandingan baku mutu dan menggunakan tingkat efektivitas IPAL melalui rumus yang telah ditetapkan. Hasil: Hasil penelitian menunjukkan biofilter anaerob-aerob sangat efektif mengolah total koliform pada debit puncak (99,9%), debit menengah (83,80%), debit minimum (99,9%) dan efektif dalam mengolah parameter COD 70,13% pada debit menengah, dan 74,60% debit minimum. Hasil penelitian menunjukkan biofilter anaerob-aerob cukup efektif dalam mengolah BOD (54,59%) dan TSS (50%) dan kurang efektif mengolah fosfat (40,7%). Analisis data menunjukkan bahwa hasil pengolahan air limbah rumah sakit provinsi NTB telah memenuhi baku mutu yang telah ditetapkan. Simpulan: Biofilter anaerob-aerob efektif meningkatkan kualitas air limbah rumah sakit. Dampak dari proses pengolahan ini akan  mengurangi pencemaran lingkungan.
