Abstract

Liquid organic fertilizer has been developed to reduce the dependence of cultivated plants on inorganic fertilizers. based Oil palm fruit fiber, as a by-product of processing palm oil mills, potentially used as organic fertilizers. The purpose of this study was to obtain liquid organic fertilizer from fermented oil palm fruit fiber and analyze the effect of the fertilizer on the growth of oil palm seedlings. Two stages of the research were conducted. The first stage was processing the fibre into liquid organic fertilizer by chopping the oil palm fruit fiber and adding local microorganisms as activators. The fermentation process was carried out for 7 days. The second stage was applying fermented organic fertilizer (POC) to the oil palm growing media. The Completely Randomized Design Method was applied with 5 treatments, namely: P0 (subsoil with no fertilizer), P1 (soil + NPK), P2 (soil + 20 ml POC), P3 (subsoil + 40 ml POC), P4 (subsoil + 60 ml POC). The POC was applied once every week for 16 weeks. The results showed that liquid organic fertilizer had a significant effect on the height of palm seedlings at 4 MAP at 20 ml per seed. The oil palm seed growth tend to increase in several parameters observing in plant diameter, plant biomass and leaves greeness. Liquid organic fertilizer obtained from oil palm fruit fiber can be applied as alternative fertilizer in the prenursery. Further research related to the optimization of process producing liquid organic fertilizer and its application to other cultivated plants is highly recommended.

Abstract

Fiber (mesocarp fiber) is a solid waste generated in the oil palm factory which potentially used as fertilizer through composting. Addition of Azotobacter sp. in composting can increase nitrogen content, which improve the quality of compost. The purpose of this research was to determine the effect of the enrichment of Azotobacter sp. in composting of oil palm pressed fiber and analyzing the nutrient content and its potential as a planting medium of pakcoy (Brassica rapa). Descriptive method was used in the process of composting by assessing the physical and chemical properties of the compost produced. Fiber compost testing as a planting medium was carried out using a nonfactorial Randomized Complete Block Design in 3 variations of 30%, 50% and 70% treatment, and each mixed with subsoil. The results of compost physical parameters analysis showed the dark brown color, and the texture showed more crumb in the compost enriched with Azotobacter sp. The best pH was found in the compost treated with the addition of Azotobacter sp., which was 8.36. Analysis of compost application on pakcoy growth showed that the highest leaf area (69.73 cm2) and number of  stomata (36.4 mm2)-1) were found in the F2P2 treatment (Azotobacter Fiber Compost 50% + Subsoil 50%); The highest root length (28.38 cm), shoot dry weight (2.58 g), and root dry weight (2.26 g) were found in the F2P3 treatment (Azotobaacter Fiber Compost. 70% + Subsoil 30%). From the results of these experiments, the compost enriched with azotobacter has beneficial effects on crop growth could be attributed to soil amendments.

Abstract

Organic materials as industrial by-products are potentially used as alternative growth media composites with the aim of reducing the use of top soil and improving the quality of plants in the nursery. Mesocarp of palm fruit (fiber) and coconut fiber powder (cocopeat) are rich in plant nutrients. Composting of these by-products will be helpful in recycling and re-use of biodegradable waste useful for growing media. This research use Completely Randomized Design (CRD) one factor consist of 4 treatment. The treatment were (a). P0 = sub soil 100% (control), (b). P1 = 50% mesocarp fiber composts + 50% sub soil, (c). P3 = 50% cocopeat composts + 50% sub soil, and (d). P3 (mesocarp fiber 1 kg + cocopeat fiber 0.5 kg + 0.5 kg cattle dung) composts + sub soil 50 %. Growing media that consists of 50% mesocarp fiber and 50% sub soil (P2) was suitable as growing medium in early seedling. Compost of mesocarp fiber has the content of C-organic 52,28%, N 1,37%, C / N ratio 38,11%, P2O5 0,47%, K2O 0,89%, Mg 0,23%. The use of composted mesocarp fiber media mixed with 50% sub soil showed significant effect on the growth of seed diameter of oil palm seedlings at age 3 MAP.
