Abstract

Clean water services in Pangkalan Lesung Subdistricts in Pelalawana Regency still relies from bottle water, boreholes, river water, springs and rainwater, the quality and quantity of these sources not quaranteed. The need for water in Pangkalan Lesung District in 2038 reaches 144,24 l/sec. so it is necessary to plan a drinking water supply system for the next 20 years using raw water from the Kuyo River. Based on th mass balance analysis, it is found that units capable of processing raw water with water quality are in accordance withPERMENKES number 492 in 2010. The processing unit are planned for intake, pre-sedimentation, neutralization, coagulation, flocculation, sedimentation, filtration, disinfection and reservoar is useful for waterstorage before distribution. The volume of reservoar required is 1869,3 m3and need to do the addition of the distribution pump with capacity is 60 l/s and head pump is 55 m to drain the water to service area. The creationof a distribution network using the software EPANET 2.0 with trial and error in inserting the value of the pipe diameter so that it meets the technical criteria for design. The budget required for planning a drinking watersupply system in Pangkalan Lesung District is Rp. 79.969.000.000,-Keyword: Pangkalan Lesung, Water Requirements, Production Units, EPANET 2.0, Distribution.

Abstract

The conventional composting technique of oil palm empty bunches takes several months or even a year to reach maturity because it has a high C / N ratio (64.46) and lignin polymer bond (27.60-32.50%) which hard to degrade. Using Merang Mushroom (Volvariella volvacea) as pretreatment before composting is expected to decrease lignin level and accelerate degradation of empty palm bunches. Merang Mushroom (Volvariella volvacea) is one of white rot fungus which able producing enzymes to degrade the lignin structure became simpler. The purpose of this study is determine the profil temperature in composting process of spent mushroom media by addition Palm Oil Mill Effluent (POME).This study was conducted by varying the comparison of TKSJ: POME (1: 0, 2: 1, 1: 1 and 1: 2 w / w) with in vessel composting model. The results showed the temperature in this process reachs standard SNI 19-7030-2004 (28-29 oC). Keywords: Merang Mushroom, POME, C/N and Composting

Abstract

Composting is one of the best methods for handling empty fruit bunch (EFB) waste. This research aims to learn effect variation of additions Palm Oil Mill Effluent (POME) in composting process of EFB spent paddy straw mushroom (Volvariella volvacea) toward C/N ratio. Palm Oil Mill Effluent (POME) was added gradually (in day 0, 7th, and 14th) and variation of substrate mixture (EFB spent paddy straw mushroom : POME) are 1:0; 1:1; 1:2; and 1:3. The result shows the composting process finish in the day 7th (faster than research estimate, with 1 time POME addition) and the best variation of substrate mixture is (D) (1:3). The mature compost has C/N ratio 13,07. Key words : EFB spent paddy straw mushroom, C/N ratio, Composting, POME

Abstract

Palm Oil Mill Effluent (POME) is highly polluting wastewater with high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in which can caused severe pollution to the environment, typically pollution to water resources. On the other hand, POME was identified as potential source to generate renewable bioenergy through anaerobic digestion. Anaerobic processes need seeding and acclimatization so the microorganism could be adapted. The acclimatization process used circulating batch reactor with worked volume 25 L and glucose and sequential waste ratio of wastewater 50:50 and 0:100 (% V/V). This research observed degradation of soluble COD and growth of VSS. Experiment results showed microbial consortium has been able to adapt to the new environment and degrade organic matter along with increasing waste volume ratio and decreasing glucose volume ratio.Keywords: Acclimatization, circulating batch reactor, Palm Oil Mill Effluent, Chemical Oxygen Demand, Volatile Suspended Solids

Abstract

Tofu industry is a domestic industry largely do not have sewage treatment units, wherewastewater directly discharge into sewers or water bodies without treatment. The aims ofstudy observation the ability of constructed wetland using T. latifolia to removal, COD andTSS. The research variations were plant and detention time. Constructed wetland reactorusing plastics with dimension 50, 36, 31cm, in length x width x height and soil mediathickness of 10 cm, 5 cm sand and 5 cm gravel. T. latifolia plant density 0, 0,5, 0,75 and 1g/cm2, and variations detention time 1,2, and 3 day. Optimal results were obtained in plantsTypha latifolia 1 g/cm2 and detention time day to 3 there are COD 200 mg/L and efficiency of92,70%; TSS 153 mg/L with efficiency 87,90%;. Anova analysis results α = 5% show thevalue COD 98,8%; and TSS 92,8%. Wich explains that the plant density factor and detentiontime affect the the concentration reduction COD and TSS.Keywords: Thypa latifolia, Constructed wetland, Detention time, Wastewater tofu.

Abstract

POME has high pollutants. POME is thick brown. The color of POME is associated with complex compounds derived from polymerization between the degraded products lignin and tannins, and POME has a high chemical composition and concentration of simple organic compounds. POME is a major source of water pollution because it is difficult to decompose and is dangerous for the environment. This research aims to investigate the characteristics of POME by analysis using ozonation. The results showed an decrease in COD from 58.144 mg/L to 56.181 mg/L. Keywords: POME, ozonation

Abstract

PM2.5 pollutant are very harmful to human because it has a very small size which can infect the human lungs easily. Distribution of particulate is very difficult to seen by human eyes. One of the ways to know distribution of particulate besides direct measurement in the field is using a model. The model used is AERMOD VIEW. This research was conducted to know the pattern of emission distribution from boiler and incinerator chimney in annual scenario by doing windrose analysis. The results of modeling show distribution of pollutant tends leads to the southeast and north from PTPN V Sei Galuh. Distribution of particulate from the source is affected by wind direction characteristic.Keywords: AERMOD VIEW, PM2.5, palm oil industry.

Abstract

Palm Oil Mill Effluent (POME) contains high concentrations of organic pollutants. The high organic concentration in POME makes it suitable reused as an energy source. This study aims to investigate the characteristics of POME and analyze the potential of POME. The results of this study indicate the concentration of total and soluble COD in POME 32,000 mg / L and 16,000 mg / L, VSS amounting to 6,000 mg / L and pH 4.2. With high organic concentration then POME can be utilized as bioethanol and biogas. Keywords: Palm Oil Mill Effluent (POME)

Abstract

The empty fruit bunch (EFB) is a solid waste from palm oil processing with the highest percentage of 23% per ton of the fresh fruit bunch (TBS), which has not been optimally utilized from the palm oil industry. EFB have 15-30% lignin components and complex chemical composition which is difficult to be degraded. To be easily converted into a simpler element, the bunches have to be firstly degraded. The utilization of the empty bunches as a medium to the growth of paddy straw mushroom (Volvariella volvaccea) is expected to degrade the content of lignin. The mushroom (Volvariella volvacea) produces extracellular enzymes in the form of LiP and MnP in degrading lignin. This study aims to study the effect of environmental conditions on the growth of straw mushrooms (Volvariella volvacea) on lignin degradation. This study has variation of seed mushroom weight of which 250 gr, 350 gr and control. The best results show that the highest percentage of lignin declining was found in the increasing weight of 250 gr paddy straw mushroom seeds which was 61%, with the achievement of optimum environmental conditions such as temperatures in the range 27.2-30.6 0C, pH 7.0-7.36 and water content of 42-85.2%. The conclusion of this study is that the optimum environmental conditions during the growth of the mushroom (Volvariella volvacea) become an important factor in the process of lignin degradation in the waste of EFB. Keywords : EFB, Lignin, pH, Temperature, Moisture content, Degradation
