Abstract

Air lindi merupakan limbah cair yang berpotensi menimbulkan pencemaran lingkungan karena kandungan senyawa-senyawa yang bersifat toksik serta mikroorganisme patogen. Oleh karena itu, air lindi tidak boleh dibuang ke badan air tanpa penanganan terlebih dahulu dan diketahui kualitasnya. Penelitian ini bersifat deskriptif kualitatif yang bertujuan untuk analisis kualitas air lindi dari landfill TPA sampah Muara Fajar Kota Pekanbaru ditinjau dari aspek biologi, fisika, dan kimia. Sampel air lindi diambil dari 6 titik sampling yaitu pada parit pembuangan awal (inlet - PA), kolam proses pengendapan (K1), kolam proses anaerob (K2), kolam proses aerasi (K3), kolam proses penjernihan (K4) dan bak penampungan akhir (outlet - BPA). Parameter yang dianalisis meliputi pengukuran BOD, COD, pH, temperatur, NH3N, dan TSS yang ditentukan menggunakan metode standar. Selain itu juga dihitung indeks MPN menggunakan metode Most Probable Number dan deteksi keberadaan Salmonella dan Shigella menggunakan medium SSA. Hasil penelitian menunjukkan bahwa COD tertinggi dan terendah terdapat pada kolam PA dan kolam BPA dengan nilai berturut-turut yaitu 23.125 mg/l dan 3.750 mg/l. Nilai BOD tertinggi dan terendah pada kolam K3 dan kolam PA dengan nilai 1105,5 mg/l dan 393,4 mg/l. Nilai TSS tertinggi dan terendah pada kolam PA dan kolam K4 yang memiliki nilai 1,4 mg/l dan 0,7 mg/l. Indeks MPN tertinggi dan terendah pada PA, K1 dan BPA yang memiliki nilai ≥2400 dan <2. Salmonella sp. diketahui positif terdapat pada semua titik sampling, sebaliknya tidak ada Shigella sp. pada semua titik sampling. Nilai COD, BOD, dan indeks MPN dari air lindi untuk setiap titik sampling belum memenuhi baku mutu lingkungan, kecuali indeks MPN untuk kolam BPA telah memenuhi baku mutu lingkungan. Air lindi TPA Sampah Kota Pekanbaru belum dinyatakan layak sesuai dengan baku mutu lingkungan.

Abstract

Biogas is one of alternative energy sources that fulfills future fuel needs. This studyaimed to analyse the potency of sago waste as fermentation substrate for biogasproduction. This research was done experimentally by employing sago waste materialsobtained from Sago Factory Nambus River from District West Tebing Tinggi Sub-province Meranti and fresh cow rumen liquid was obtained from slaughterhouse inPekanbaru. The biogas volume was calculated by measuring the volume of water thatwas pushed every 3 days, where the volume of water driven was proportional to thevolume of biogas produced. The bacterial cell numbers was counted using plate countmethod employing Nutrient Agar (NA). The substrate fermentation temperature and pHwere measured every 3 days. The highest biogas volume was produced by fermenter III(45760 ml) containing solid sago waste, liquid sago waste, and rumen liquid with ratio 1: 1 : 1 and the lowest was produced by fermenter II (1600 ml). The total bacterialinvolved in biogas production ranges from 1,87x10 5 – 2,87x10 8 CFU/ml samples. Thetemperature and pH of substrate fermetation was relatively constant during biogasproduction. The results showed that sago waste is potential as substrate for biogasproduction.

Abstract

Indole Acetic Acid (IAA) is one of group of auxin phytohormones and plays a role to improve plant growth. Beside plants, fungi are also known to be able to produce IAA.This study aimed to select the ability of fungal isolates collection of Microbiology Laboratory, Faculty of Math and Natural Sciences University of Riau in IAA production. Fungal isolates were cultured in medium PDB (Potato Dextrosa Broth)enriched by tryptophan as a precursor of IAA. Indole acetic acid produced by fungi was detected by adding Salkowski reagent and determined quantitatively by the use of colorimetric method. The results showed that 47 fungal isolates were able to produce IAA. The highest IAA production was revealed by isolate RPL4-14 (646,75±0,35 ppm) and the lowest was shown by isolate RPL2-x (4,00±3,53 ppm) when they were culturedin PDB medium enriched by tryptophan. The fungal collection did not only produce IAA in the medium containing tryptophan, but also in the medium without tryptophan as shown by isolate RPL3-10, which has IAA concentration i.e 76,50±0,00 ppm and71,00±0,70 ppm, respectively. Isolates which produced the highest IAA concentration are identified as Penicillium sp.
