The high availability of slurry from palm oil mill effluent, solid, and boiler ash with their nutrient contents make those three materials are potential to be processed become organic fertilizer in the form of pellet so it tends to has slow release characteristic. This research aims to analyize characteristic of organic fertilizer pellet from slurry of palm oil mill effluent as slow release fertilizer by analyzing its physical characteristics, NPK content, and NPK releasing rate in soil.Slurry was processed become solid fertilizer in the form of pellet using pellet mill with tapioca adhesive 5%. Pellet was made from slurry, solid, and boiler ash which were mixed with ratio 1:1:1, 1:2:2, 2:1:1, 2:2:1, 2:1:2, 1:0:0 (only slurry). This research ware analysis of physical characteristis (length, diameter, and density) and analysis of NPK content. N content was analyzed using Kjeldahl method, P content using spectrophotometer, and K content using Atomic Absorbtion Spectrophotometer (AAS). Then it was continued with analysis of NPK releasing content in latosol soil.The average length of pellets was 31–48 mm, diameter was 5,42 – 6,28 mm, water content was 0,426 – 0,976%, particle density was 1,04 – 1,34 g/cm3, and bulk density 0,49–0,63 g/cm3. Organic fertilizer pellet in six formulas contained N+P2O5+K2O about 5,93–8,08%. The highest content (8,08%) was produced from 1:0:0 pellet, followed by 2:1:2 formula (7,53%), and 1:2:2 formula (7,25%). Until the 10th days, the releasing of N element was about 1,99 – 3,18%, P element was 0,063– 0,075%, and K element was 43,54 – 62,26%.

Organic fertilizer can yield higher production compared to regular fertilizer if properly applied. Thus, it can be a solution to improve nutrient content of soil. The biggest source of bio slurry in plantation is from Palm Oil Mill Effluent (POME) and cow dung biogas. This research aimed to analyze the residue’s potential from the result of biogas processing and bio slurry from POME as slow-release fertilizer pellet. Bio slurry was processed into pellet through densification process using pellet mill. The research was arranged in a Randomized Block Design method with five slurry compositions as treatments, including 70:30, 60:40, 50:50, 40:60, and 30:70 (ratio of biogas slurry and POME slurry), each consisted of three replications. According to the data obtained, fertilizer pellets had characteristics of 25 – 29 mm of length, 5.23 – 5.85 mm of diameter, 0.44 – 0.53 g/cm3 of density, 54.78% - 81.96% of durability, and 7.81% - 8.57% of moisture content. Based on density and durability aspects, 30:70 composition was the higher. Macronutrient content of the five compositions were 1.88% - 2.72%, in which on day 22, N, P, and K release was 0.36 – 1.01%, 73.51 – 97.48%, and 3.19 – 7.85%, respectively. Meanwhile, on day 17, the nutrition solution conductivity of all compositions had already reached 0.80 – 1 mS/cm.

Production of agricultural wastes is increasing while soils are progressively losing organic matter due to intensive cultivation and climatic conditions. This makes the recycling of organic wastes a useful alternative to incineration, landfill or rubbish dumps. The effects of two agro- wastes and mineral fertilizer on growth and yield of leaf amaranth were assessed in a pot experiment at the Teaching and Research Farm, Ekiti State University, Ado-Ekiti. Treatments consisted of poultry manure (PM) and palm oil mill effluent (POME) each applied at 8 and 16MT/ha while NPK 15-15-15 was applied at 150, 200kgha-1 and no fertilizer as control. Seeds of amaranthus caudatus variety were sown in plastic pot (50x20x40cm) containing 20kg top soil. Treatments were arranged in a randomized complete block design replicated three times. Data were taken on plant height, stem girth, number of leaves plant-1, leaf area, root length, fresh weight, dry weight, edible yield and above ground plant weight at 6 weeks after planting. The results revealed that the agrowastes significantly (p<0.05) resulted in better performance of leaf amaranth. Application of 16MT/ha PM gave the highest fresh and edible weight of 211.23 and 98.80g respectively. POME also performed better than NPK fertilizer in some of the parameters measured. This indicated that PM and POME could serves as an alternative sources of nutrient to mineral fertilizer for leaf amaranth and also a sustainable fertility management strategy for crop production.

Processing of palm oil generates enormous quantities of wastewater commonly called palm oil mill effluent (POME). The aim of the research was to evaluate the effect of POME as organic fertilizer on Melaleuca cajuputi seedling. The research was conducted at PT. Bukit Asam from November 2016 until March 2017. POME used was from PT. Bumi Sawindo Permai at Tanjung Enim, South Sumatera. POME from Fat pit, cooling pond, anaerob pond and maturity pond were applied to seedlings at nursery with different concentrations of POME Fat pit (625, 417, and 208 mL), Cooling pond (695, 463, dan 232 mL), Anaerob pond (738, 492, dan 246 mL), and Maturity pond (968, 645, dan 323 mL). The result showed that POME from Anaerob pond 246 mL increased the growth of M. cajuputi with plant high 47.35 cm and stem diameter 5.57 mm and total dry weight of CM (Calopogonium mucunoides) was 26.83 g.Key words: ex-coal mine soil, Melaleuca cajuputi, POME

The aims of this study was to investigate the characteristics and physicochemical changes of vermicompost during composting of palm oil mill effluent (POME) sludge processed by epigeic earthworm (E. eugeniae) within 60 days. The value of macronutrients, micronutrients and heavy metals and pH in vermicompost comes out to be (pH8.3), carbon (C) (45.2%), CN ratio (18.1%), phosphorus (P) (5.02%), ferum (Fe) (0.6%), copper (Cu) (16.8 ppm), zink (Zn) (119.54 ppm), mangan (Mn) (1049.86 ppm), potassium (K) (0.81%), nitrogen (N) (2.5%), calcium (Ca) (11.42%) and magnesium (Mg) (2.99%), and was compared with compost from EFB-POME sludge and compost from mesocarp fiber-POME sludge. In addition, the amino acid content in vermicompost detected was very low as compared to raw POME. Meanwhile, three types of fungus were detected in vermicompost which are fromPaecilomycessp.,Fusariumsp. andPenicilliumsp. The results suggested that POME sludge could be recycled to form compost by using vermicomposting technology, as well as act as a good organic fertilizer.
