PENGARUH WAKTU FERMENTASI DAN KOMPOSISI LIMBAH KULIT BUAH AREN (Arenga pinnata) DENGAN STARTER KOTORAN SAPI TERHADAP BIOGAS YANG DIHASILKAN

Sugar palm or commonly called as Aren (Arenga pinnata) is a multipurpose crop. The widely use of sugar palm for food industries, generates sugar palm leather waste which can be used as a biomass for biogas production. This study aims to determine the quality and the quantity of biogas made from a mixed of sugar palm leather waste and water using batch anaerobic digester system and to evaluate the economic potential of biogas production from the mixture. Research carried out by mixing sugar palm leather with water in a ratio of 1:13; 1:11,5; 1:10; 1:9; and 1:8 (w/w) with cow dung as a starter mixed with water in an anaerobic digester batch system. Observed variables are biogas, biogas composition, Total Suspended Solid (TSS) and Chemical Oxygen Demand (COD) and analyzed fermentation slurry for every 3 days. pH for this study is set in the range of 6,4-8. The largest volume of biogas production is found at a ratio 1:11,5 (w/w) mixture of sugar palm leather and water that is 637 mL for total waste 1,5 L with 60,983 % methane contain. TSS removal percentage obtained was 88,10 %and percentage of COD removal by 82,43%. Slurry produces unqualified TSS and COD with the standard quality of liquid waste. The economic potential of sugar palm leather waste and water for producing biogas is beneficial.

Water used for washing carcasses of slaughtered animals and slaughter house is referred to as abattoir wastewater. This study was designed to investigate the microorganisms associated with abattoir wastewater and to establish the biodegradation potential of abattoir wastewater microbiota. Isolation of the microbes was carried out using pour plate technique. The total viable count for the microbes’ ranges from 2.5×104 - 4.6×105 cfu/mL. Results revealed that all the physicochemical parameters exceeded the permissible limits (total dissolved solid (TDS) 1748mg/L, total suspended solid (TSS) 176mg/L, biochemical oxygen demand (BOD5) 91 mg/L and chemical oxygen demand (COD) 227 mg/L). Microorganisms isolated include Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Bacillus anthracis, Aspergillus niger, A. flavus, Mucor sp, Trichophyton quickeanum and Penicillium sp. Some of the microbes were observed to have biodegradation potential by their ability to grow on mineral salt media (MSM) incorporated with starch, cellulose, crude oil, kerosene and diesel as the sole source of carbon and energy. This study suggests that abattoir wastewater harbors microorganisms that could be hazardous to public health when discharged into the environment untreated hence the need for strict monitoring. These microbes isolated could be employed as agent of bioremediation of wastewaters. Key words: Abattoir; Biodegredation; Isolation; Microbiota; Wastewater

Average Analysis

The efficiency of biogas production in semi-continuous anaerobic digester is influenced by several factors, among other is loading rate. This research aimed at determining the effect of hydraulic retention time (HRT) on the biogas yield. Experiment was conducted using lab scale self-designed anaerobic digester of 36-L capacity with substrate of a mixture of fresh cow dung and water at a ratio of 1:1. Experiment was run with substrate initial amount of 25 L and five treatment variations of HRT, namely 1.31 gVS/L/d (P1), 2.47 gVS/L/d (P2), 3.82 gVS/L/d (P3), 5.35 gVS/L/d (P4) and 6.67 gVS/L/d (P5). Digester performance including pH, temperature, and biogas yield was measured every day. After stable condition was achieved, biogas composition was analyzed using a gas chromatograph. A 10-day moving average analysis of biogas production was performed to compare biogas yield of each treatment. Results showed that digesters run quite well with average pH of 6.8-7.0 and average daily temperature 28.7-29.1. The best biogas productivity (77.32 L/kg VSremoval) was found in P1 treatment (organic loading rate of 1.31 g/L/d) with biogas yield of 7.23 L/d. With methane content of 57.23% treatment P1 also produce the highest methane yield. Biogas production showed a stable rate after the day of 44. Modified Gompertz kinetic equation is suitable to model daily biogas yield as a function of digestion time.Article History: Received March 24th 2018; Received in revised form June 2nd 2018; Accepted June 16th 2018; Available onlineHow to Cite This Article: Haryanto, A., Triyono, S., and Wicaksono, N.H.

In this paper three sustainable approaches are made in waste management option. Firstly primary treated domestic sewage is treated by aquatic macrophytes using duckweed, water hyacinth and water lettuce. Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Phosphate, Nitrates are tested before and after. Result indicates in terms of water quality, almost all three plants shows same removal efficiencies. BOD and TSS removal efficiency is attained more than 95%. COD and TDS removal is reached upto 50% for almost all plants. Secondly the used aquatic macrophytes for wastewater treatment is again used for generation of biogas (water lettuce unit, duckweed unit, water lettuce unit). In addition to three aquatic macrophytes, sludge is collected from aquatic macrophyte unit for generation of biogas. Comparison is made with conventional cow dung biogas unit. Result indicates water lettuce and duckweed produce biogas at earlier stage itself and water hyacinth takes some time for starting of biogas production. This may be due to the structure and texture causes some time for decomposition. Sludge gives maximum biogas generation among all experimental setup. Also in this study cow dung did not give biogas more may be due to poor blend ratio of cow dung with water is one of the reason.

Kualitas air di suatu wilayah yang merupakan salah satu indikator lingkungan dapat dievaluasi menggunakan parameter fisika, kimia, dan biologi. Indeks Kualitas Air Indonesia (IKA-INA) dapat digunakan untuk menilai kondisi kualitas air secara menyeluruh pada lokasi dan waktu tertentu. IKA-INA dihitung dengan menggunakan sepuluh (10) parameter yaitu pH, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), NO3, NH3, Total Phosphate (TP) dan fecal coliform. IKA-INA tersebut merupakan indeks kualitas air yang dapat memberikan informasi secara sederhana. Dalam pemanfaatannya, tidak semua data parameter dalam IKA-INA tersebut dapat terpenuhi karena adanya data tidak valid atau data yang hilang. Kajian ini bertujuan untuk memberi alternatif rumusan IKA-INA dengan parameter yang tidak lengkap atau jika tidak semua data dalam parameters tersebut tersedia. Metode yang digunakan dalam menyusun rumusan adalah dengan melakukan koreksi faktor bobot parameter IKA-INA terhadap parameter yang hilang dan nilai Q (nilai sub-indeks). Setelah itu dilakukan uji coba pada nilai baku mutu air dalam Peraturan Pemerintah No. 22/2021 Lampiran VI serta pada data kualitas air sungai yang mewakili kualitas baik dan buruk. Hasil uji coba menunjukkan bahwa bobot parameter terkoreksi dapat digunakan untuk penanganan parameter yang hilang dalam penilaian kualitas air dengan metode IKA-INA. Hasil IKA-INA dengan parameter hilang yang menggunakan bobot terkoreksi dan hasil IKA-INA dengan parameter lengkap mayoritas memberikan status IKA yang tidak berbeda, kecuali untuk parameter fecal coli dan parameter yang mempunyai kadar jauh berbeda terhadap kondisi air secara keseluruhan.
