Abstract

This study aims to determine the effect of modified natural zeolite as microbial immobilization medium for anaerobic decomposition of organic materials. The modification was Fe2+ impregnation into the ring-shaped zeolite. Three different concentrations of Fe2+ solution were used to impregnate the zeolite, i.e. 10 mg/L, 100 mg/L and 2000 mg/L. The wet impregnation process was conducted. Four variations of Fe2+ concentration deposited into zeolite were prepared, i.e. 0 mgFe2+/gZeo (as control), 0.0016 mgFe2+/gZeo, 0.0156 mgFe2+/gZeo and 0.3125 mgFe2+/gZeo. The modified zeolite was added to the batch anaerobic reactor, which filled with the volume ratio of liquid substrate and zeolite of 1:1 for all variations of media. Distillery spent wash was used as the substrate in this study. The soluble Chemical Oxygen Demand (sCOD) value of the substrate was homogenized at 10000 mg/L. Effluent digester of cow manure bio digester was added as inoculum. The volume ratio of distillery spent wash to the inoculum was 2:1. The anaerobic process was conducted for 28 days.The performance of four media in the anaerobic digestion of distillation spent wash was measured in terms of sCOD, total solid (TS), and volatile solid (VS). The comparison among media was more accurately and conclusively represented by sCOD value. The visual analysis of sCOD trend during 28 days indicated that zeolite with 0.0156 mgFe/gZeo resulted in the highest sCOD removal of 66.73%. Meanwhile, zeolite with 0.3125 mgFe/gZeo increased the production of biogas by the highest percentage of 43% to be compared to control. Generally speaking, the addition of Fe2+ into zeolit led to higher removal of sCOD and produced more biogas than control.ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penambahan zeolit alam termodifikasi sebagai media imobilisasi terhadap dekomposisi material organik pada proses anaerobic digestion. Modifikasi yang dilakukan adalah dengan cara mengimpregnasi ion besi(Fe2+)ke dalam zeolit yang telah dibentuk menjadi cincin Raschig. Impregnasi yang dilakukan adalah impregnasi basah. Dalam penelitian ini digunakan 3 variasi konsentrasi larutan Fe2+ yaitu 10 mg/L; 100 mg/L dan 2000 mg/L. Dari hasil impregnasi zeolit menggunakan ketiga konsentrasi tersebut diperoleh kadar Fe2+ yang terdeposit ke dalam zeolit berturut-turut: 0,0016 mgFe2+/gZeo; 0,0156 mgFe2+/gZeo; 0,3125 mgFe2+/gZeo dan 0 mgFe2+/gZeo digunakan sebagai kontrol. Zeolit termodifikasi Fe2+ kemudian ditambahkan ke dalam reaktor anaerobik yang dijalankan secara batch. Perbandingan volume media zeolit dan cairan adalah 1:1. Substrat yang digunakan berupa campuran limbah distillery spent wash dengan konsentrasi soluble Chemical Oxygen Demand (sCOD) 10.000 mg/L dan keluaran dari digester aktif kotoran sapi sebagai inokulum. Perbandingan volume distillery spent wash terhadap inokulum sebesar 2:1. Proses anaerobik dijalankan selama 28 hari. Jika dibandingkan dengan data Total Solid (TS) dan Volatile Solid (VS), hasil percobaan menunjukkan bahwa data analisis sCOD memberikan data yang lebih akurat dan konklusif untuk mengukur perubahan material organik dalam proses peruraian anaerobik menggunakan media imobilisasi. Dari keempat variasi kadar Fe2+ yang digunakan dalam penelitian ini, Fe2+ dengan kadar 0,0156 mgFe/gZeo memberikan efisiensi penurunan material organik (sCOD) tertinggi yaitu 66,73%. Sedangkan Fe2+ dengan kadar 0,3125 mgFe/gZeo mampu meningkatkan produksi biogas sebesar 43%. Namun secara keseluruhan proses peruraian anaerobik yang menggunakan zeolit termodifikasi Fe2+ menghasilkan biogas lebih banyak daripada kontrol (zeolit tanpa Fe2+).

Abstract

The production of crude palm oil (CPO) in Indonesia tends to increase over time. Palm oil mill effluent (POME) is the wastewater generated from the palm oil mill process with high organic content. POME is a potential source for anaerobic digestion due to its high organic content. The challenge of POME treatment using an anaerobic process is to enhance biogas production with high soluble chemical oxygen demand (sCOD) removal efficiency. The purpose of this study was to evaluate the effect of selected trace elements addition onto zeolite as immobilization media to the anaerobic digestion of POME in a fluidized batch system. Natural zeolite was used as the medium to immobilize microorganisms in an anaerobic fluidized bed reactor (AFBR). This study used three trace elements impregnated to natural zeolites, i.e. Ni2+, Zn2+, Mg2+. The result shows that Ni2+ and Zn2+ improve the methanogenesis process, prevent the accumulation of VFA as an intermediate product and increase the methane (biogas) production. Meanwhile, Mg2+ only reduced sCOD significantly but it did not affect methane production. Fluidization enhanced the performance of the POME anaerobic digestion process. The fluidization provide a positive effect to enhance biogas production and sCOD removal. The efficiency of sCOD removal in the entire reactors were 80.82%; 81.77%; 75.89% for AFBR-Ni; AFBR-Zn and AFBR-control respectively. The total volume of methane produced by the three AFBR were 163,04; 136,42; 62,79 (in ml CH4 / g sCOD) for AFBR-Ni; AFBR-Zn and AFBR-control, respectively. A B S T R A KProduksi crude palm oil (CPO) di Indonesia cenderung meningkat seiring bertambahnya waktu. Palm oil mill effluent (POME) adalah air limbah yang dihasilkan dari proses penggilingan kelapa sawit dengan kandungan organik yang tinggi. Tantangan dalam mengolah POME menggunakan proses peruraian anaerobik adalah untuk meningkatkan produksi biogas dengan efisiensi penurunan soluble chemical oxygen demand (sCOD) yang tinggi. Tujuan dari penelitian ini adalah mengevaluasi pengaruh penambahan trace element terseleksi pada media imobilisasi zeolit terhadap proses peruraian anaerobik limbah POME dengan sistem batch terfluidisasi. Zeolit alam berperan sebagai media imobilisasi mikroorganisme dalam anaerobic fluidized bed reactor (AFBR). Penelitian ini menggunakan tiga trace element yang diimpregnasikan pada zeolit alam yaitu Ni2+, Zn2+, Mg2+. Hasil penelitian menunjukkan bahwa Ni2+ dan Zn2+ sebagai trace element dapat meningkatkan proses metanogenesis dan mencegah akumulasi VFA sebagai produk antara serta meningkatkan produksi gas metana (biogas). Mg2+ sebagai trace element menurunkan sCOD dengan cukup signifikan namun tidak diimbangi dengan banyaknya metana yang dihasilkan. Fluidisasi meningkatkan performa dari proses peruraian anaerobik POME. Proses fluidisasi memberi pengaruh positif dalam meningkatkan produksi biogas dan soluble chemical oxygen demand (sCOD) removal. Nilai sCOD removal yaitu 80,82%; 81,77%; 75,89% berturut-turut untuk AFBR-Ni; AFBR-Zn dan AFBR-kontrol.

Abstract

The composition of waste in Indonesia is dominated by organic waste. The waste processing process must be improved to prevent pollution in the market environment. The bioconversion process using Black Soldier Fly larvae or maggots is an effective way to process organic waste. The aim of this study was to determine the effect of feeding on the initial maggot biomass to the addition of the final maggot biomass, determine the maximum maggot weight and determine substrate consumption. This quantitative research used a completely randomized design method consist of five treatments and four replications. The various feeding between total feed and larva were A treatment (270 gram: 150 gram), B (210 gram : 150 gram), C (150 gram : 150 gram), D ( 90 gram : 150 gram) and E ( 30 gram : 150 gras). The data analysis technique used variance test and Duncan’s mean difference test. The result showed that the addition of coconut pulp feed affects to the final weight of the maggot and the value of substrate consumption. The addition of coconut dregs feed which maximally affects to the final weight of the maggot showed in A treatment which ratio coconut dregs: larva (270 gram : 150 gram). The A treatment gave an average final weight of maggot 195 grams in 18 days. The maximum reduction of coconut dregs in the bioconversion process was observed in treatment E with a substrate consumption value of 55%.

Abstract

Sampah plastik  menjadi salah satu limbah padat yang di hasilkan oleh masyarakat. Sampah plastik sangat berbahaya bagi lingkungan karena plastik tidak mudah membusuk dan sulit diuraikan. Perlu adanya kesadaran dan peran aktif dari masyarakat untuk menangani permasalahan sampah plastic. Salah satu cara penanganannya yaitu dengan program 3R ( Reuse, Recycle, Reduce). Contohnya adalah bekas air kemasan yang sudah tidak memiliki nilai diolah dan di daur ulang menjadi sesuatu yang lebih bermanfaat dan memiliki nilai ekonomis.  Plastik tidak hanya menjadi sumber masalah tetapi di sisi lain sampah plastik justru memberikan peluang bisnis. Pelatihan daur ulang sampah plastik ini bertujuan agar peserta dapat memiliki keterampilan dan jiwa berwirausaha hasil daur ulang sampah plastik. Metode yang digunakan meliputi penyuluhan dan pelatihan serta praktek langsung. Hasil kegiatan menunjukkan bahwa program PkM dapat dilaksanakan dan direspon dengan baik oleh  ibu-ibu PKK Desa Bugel, Kecamatan Ciawi, Kabupatan Tasikmalaya. Peserta pelatihan terlihat sangat antusias dalam membuat aneka kerajinan dari sampah plastik.
