Extraction and characterization of humic acid from plantation’s solid organic waste composts Ekstraksi dan karakterisasi asam humat dari kompos limbah padat organik perkebunan. Menara Perkebunan, 68 2 Namun, metode tkkz dan substances. However, there is little information on karakteristik asam humat asal kompos tersebut belum extraction and characteristics of HA from the SOW- banyak diteliti.

Oleh karena itu suatu rangkaian originated composts. An investigation has been penelitian dilakukan dengan tujuan memperoleh paket conducted to determine extraction and characterisation teknologi ekstraksi dan menetapkan karakteristik asam of HA from empty fruit bunches of oil palm EFBOPhumat asal kompos tandan kosong kelapa sawit cocoa pod husks CPHand tea cutting residues TCR.

Pengomposan dilakukan melalui tahapan involved SOW collection, shredding, mixing with pengumpulan limbah organik padat perkebunan, bioactivator, incubation, and harvesting.

The results pencacahan, pencampuran dengan bioaktivator, showed that conventional extraction method using inkubasi dan pemanenan. Hasil penelitian NaOH solution under air atmosphere could be used for menunjukkan bahwa metode ekstraksi konvensional pilot scale extraction of humic acids Has. Jumlah that of CPH. The composting period tkis the extraction asam humat yang dihasilkan dari kompos asal TKKS method under air or N2 gas were not significantly dan SPT lebih banyak apabila dibandingkan dengan affected the amount of the humid acid obtained.

Pemurnian asam with lower molecular komps fractions and humat asal ketiga jenis LPO perkebunan dengan predominated by aspartic and glutamic acids.

kojpos Introduction characterization of HA isolated from different materials Deiana et al. Several methods are organic N sources for callus development available for the extraction and isolation of HA. HAs are less Extraction procedures and extracting reagents of susceptible to microbial degradation than low HA have been developed based on the principles molecular weight acids and represent a potential where humic materials are soluble in dilute base.

Moreover, humic substances are used were predominantly of intermediate and low widely in modern agriculture as humic fertilizer molecular-weight compounds. Sodium hydroxide that has been produced on industrial scale Garcia solution, despite its oxidation effects, was the best et al.

The commercial HAs commonly solvent tested for the extraction which were taken from lignite or leonardite, coal, peat, and representative for a wide range of soil humic other geologic deposits that inconsistent, limited substances Kpmpos et al.

Compost of solvent under air to meet condition of extraction.

Humic acid obtained from Kertajaya, Rajamandala, from fractions of soil organic matter are highly and Montaya estates, West Java. Experiment were attributed to the quality and quantity of the carried out at Ciomas Experimental Garden for functional groups, especially oxygen Challa et composting and Analytical Laboratory of al.

Composting procedures have followed Shimadzu. In Characterization of macromolecular brief, composting steps involved SOW collection, structure of HAs can be conducted in several shredding, mixing with bioactivator, incubation, ways, such as infrared spectrophotometry. Shredding was conducted on-site, analyses were performed for identification of whereas composting was carried out at Ciomas functional groups of HAs in the extracts.

Infrared Experimental Garden, Bogor. Dosages of IR spectra were recorded from to bioactivator were 0. The first factor was the types of SOWs, whereas the second one was levels of Results and Discussion incubation periods 0,7,14,21 and 28 d. HAs were extracted from plantation’s SOW composts Extraction and purification of humic acid from by three times of mL of 0.

In EFBOP, humic extraction was repeated by the same solvent under acid concentration increased with increasing N2 gas. Purification of HAs was conducted by incubation period up to two weeks Similar results LKB Elution pressure was assured by were obtained from CPH experiment in which, the peristaltic pump Mity Flex at constant flow HA concentration at two weeks was about E6 ratio was g. However, TCR compost contained determined according to the procedure described increasing HA concentration with increasing by Tan The slope of the spectral curve period of incubation.

The highest HA to identify molecular weight of HA was concentration of TCR occurred at fourth weeks expressed as ratio of the absorbance at and incubation These results nm E4: Statistically, there is no significant effect of Characterization of HAs extracted from incubation period on HA concentration.

It has sulphur element was determined by the method as been shown that there was not significantly described by Tan et al. Types and different between extraction conducted by concentrations of amino acids were analyzed at using NaOH solution under air and under N2 Integrated Laboratory of Bogor Agricultural atmosphere. Low molecular weight components of and simpler procedures than that of by N2 humic substances have proved to be biologically atmosphere.

The amount of extractable HAs active, because they are absorbed slightly better concentration depends on origin and type of the by plants and show higher metabolic activity than SOWs. Similar results have been reported by the higher ones Garcia et al.

The Martin et al. It can be noticed that HAs with high than 5. The presence of amino acids in the HA composts may have a high potential on the plant structure offers the possiblility of using these growth.

The similar results have been reported by Goenadi Infrared spectroscopy has been used on HA extracted from Histosols peat extensively in the past to characterize HAs and soils and Tan from tropical and temperate very useful to identify three different types of region soils.

However, the carbon elements of humic fractions. All the spectra showed a strong HA from EFBOP, CPH, and TCR composts absorption band at – cm-1, – containing large variety of amino acids in which cm-1, and cm-1, respectively the types and numbers are dependent on crop Figure 3. Tan reported that HAs exhibits types. The predominant amino acids on the three a strong absorption for C-H vibrations at SOWs investigated are aspartic and glutamic cm-1, and stronger absorption for both acids Table 2.

Aspartic and glutamic acids have carbonyl and carboxyl vibrations of COO – form similar structure, differing only in their number of at and cm The amino acid cm Therefore, absorption band at concentration of TCR compost was relatively cm Orlov assumed as silica gel contamination.

The structure reported that most of the amino acids of absorption spectra of HA from that of found in the HA was predominated by aspartic plantation’s SOWs were similar, differed only in acid-serine-glycine, whereas Coelho et al. Amino acid concentration g.

However, the role TCR has been confirmed. By using conventional of HAs on crops and microbes needs further method using NaOH solution under air condition, study.
