Abstract

Agricultural wastes able to provide profit value if utilized properly for example made into organic fertilizer. Organic fertilizer production requires microbial decomposers to help the decomposition process. This research aims to isolate and identify the characteristics of microbial decomposers found in straw compost, soil sediment from tempe lake and soil from exfarm. In this research, conducted microbial isolation. Microbial exploration of compost material, soil organic matter and soil deposition material is mixed with physiological solution then grown on PDA, further purification of the unwanted microbes. In this study only used the media to grow the asparagine fungus to see the growth of macroscopic and microscopic fungi. The results showed that there are seven isolates of the fungus from different material extraction. The extracted compost material to produce two fungi are Aspergillus sp. and Penicillium sp., Tempe lake sediment soil shows three types of fungi with Aspergillus Sp. and two types Zygomisota, while soil from Exfarm also shows two types of fungi are Aspergillus sp. and Penicillium sp. The growth rate of each different fungal isolates based sources although of the same type

Abstract

In Indonesia, there is not much use of potassium fertilizer for plants. Generally, farmers are more familiar with nitrogen and phosphorus fertilizers than potassium. This is caused potassium is expensive and hard to find, so there should be another alternative for easily and economic potassium fertilizer. This study aims to analyze the effect of organic liquid fertilizer produced from banana stem and coconut fiber to increase Potassium in soil and maize growth on ex-cassava cultivation land in Moncongloe Bulu Village, Moncongloe District, Maros Regency. The study used randomized block design within two factors and replied for three times. The first factor is coconut liquid fertilizer with 4 levels; SK1 (50 ml/pot), SK2 (100 ml/pot), SK3 (150 ml/pot) and SK4 (200 ml/pot). The second factor is banana liquid fertilizer with 4 levels; BP1 (25ml/pot), BP2 (50ml/pot), BP3 (75ml/pot) and BP4 (100ml/pot), so there are 27 total of treatment units. The results showed that coconut liquid fertilizer significantly affected plant height, number of leaves, dry matter weight, dry root weight, matter weight, root weight, organic carbon, cation exchanged capacity, percentage Potassium of maize, and gained the highest average of Pottassium increasing in soil. Nevertheless, it has not significant effect to soil pH.

Abstract

Kehadiran bakteri metanotrof pada daerah rhizosfer padi sangat dibutuhkan untuk mereduksi metan yang dihasilkan oleh bakteri metanogen, sehingga tidak terjadi emisi gas metan ke atmosfer. Penelitian ini bertujuan untuk melakukan koleksi dan seleksi bakteri methanotrof asal rhizosfer tanaman padi yang mampu menghasilkan enzim metan monooksigenase. Pengambilan sampel dilakukan secara acak pada tiga fase pertumbuhan tanaman padi yaitu fase vegetatif, reproduktif dan pematangan. Koleksi isolat dilakukan dengan metode isolasi dan pemurnian. Seleksi isolat dilakukan dengan pengujian reaksi gram, motil, indol, aerob/anaerob dan aktivitas enzim monooksigenase dianalisis dengan metode kolorimetrik.  Hasil penelitian diperoleh 52 koleksi isolat bakteri. Berdasarkan reaksi gram terseleksi 22 isolat gram negatif, berdasarkan analisis kolorimetrik  diperoleh 10 isolat  menghasilkan enzim metan monooksigenase.
