Eichornia Crassipes

Eceng gondok (Eichornia Crassipes) adalah tumbuhan yang tumbuh di perairan seperti danau, sungai dan rawa-rawa. Eceng gondok dapat dimanfaatkan sebagai pupuk organik yang terlebih dahulu harus dikomposkan. Kompos eceng gondok tidak hanya dapat membantu memenuhi kebutuhan unsur hara bagi tanaman, tetapi dapat membantu memperbaiki sifat fisik tanah.  Penelitian ini bertujuan untuk mengetahui kandungan unsur hara di dalam kompos eceng gondok dan memanfaatkan tanaman eceng gondok sebagai alternatif pembuatan kompos untuk media tumbuh tanaman di persemaian serta mengetahui efisiensi penggunaan aktivator EM4 pada proses pengomposan eceng gondok. Pembuatan kompos eceng gondok dengan metode semi anaerob menggunakan aktivator EM4 dilakukan dengan tujuan mempercepat penguraian bahan organik menjadi kompos. Proses pengomposan dilakukan selama 21 hari dan menghasilkan kompos jadi sebanyak 25,4 kg (17,15%) dengan parameter yang diamati meliputi warna, bau, suhu, kelembaban, pH, kadar unsur hara N, P, K ,Ca, Mg dan kadar C-Organik serta C/N bahan. Hasil analisis kualitas kimia kompos yang dihasilkan dari kompos eceng gondok dengan metode semi anaerob menggunakan aktivator EM4, untuk suhu rata-rata = 42,1 °C, Kadar unsur hara N = 2,00%, P = 0,582%, K = 1,87%, CaO = 2,358%, MgO = 0,390%, Kadar C - Organik = 19,29% memenuhi Standar SNI 19-7030-2004 kecuali pH = 7,82 melebihi standar.

Batur Lake is one of the natural lakes in the province of Bali where the activity of fishing, agriculture, tourism and housing available. This study aims to determine the effect of nitrate relation to the natural growth of the water hyacinth (Eichornia crassipes). Increased water hyacinth biomass in Songan station is the highest among the three other stations (Batur, Buahan, and Trunyan). At the end of the study (day 42 ), water hyacinth biomass of Songan station increased by 338.2 % from the initial weight, while at another station the increase weight  ranges from 75 % -158 %. The highest daily growth rate in Trunyan station 3.68% / day, and the lowest in station Buahan which only reached 0.88% / day. At the Songan station where are many floating net which contribute to increase nitrate. There is a tendency of growth of water hyacinth faster at higher nitrate conditions. Nitrate conditions ranged from 0,35 to 0,62 m /l which shows that the waters of Batur Lake classified into waters that have a high fertility rate (eutrophic).

The Eichornia crassipes fiber have potentially as a composite reinforcing material. The advantage of composites with natural fibers like to light weight, corrosion resistance, water resistance, attractive performance, and without machining process. The purpose of using natural fiber as an alternative material to replace glass fiber composite material with Eichornia crassipes fibers are friendly and cheap. The research material used Eichornia crassipes fiber, NaOH, Etanol, and H2O. Processing of Eichornia crassipes fiber is washing with water, natural drying ± 10 days in eviromental, fiber taking with steel brush. Dry fibre were subjected to 10%, 20%, 30% NaOH and ethanol solution with variations of immersion time of 2, 4, 6 hours, neutralization with H20, and drying at room temperature. The Single fiber tensile test specimens were made with variations of treatment type in NaOH and Ethanol solution (10%, 20%, 30%), immersion time of 2, 4, and 6 hours. Single fiber test specimens refer to standard ASTM D 3379. Optimum tensile strength test results on NaOH treatment 20% variation of immersion time 4 hours: 28.402 N / mm2 and on ethanol treatment 20% variation of immersion time 2 hours: 48.197 N / mm2.

Using biomass as a renewable energy source has earned tremendous interest from researchers in recent decades, especially because the technology is environmentally benign. This article reviews the recent methods for generating biogas from water hyacinth (WH, Eichornia crassipes), arguably the world’s most evasive aquatic macrophyte. Therefore, various economic, environmentally benign, and renewable procedures that enhance biogas production from WH biomass are reviewed. WH has been co-digested with numerous waste types, including poultry droppings, municipal wastes, animal tissue wastes, pig wastes, cow dungs, etc., recording varying success degrees. Other studies focused on optimizing the operation parameters, such as mixing ratio, contact time, pH, temperature, organic loading rate, etc. We observed that most attempts to generate biogas from WH alone were not promising. However, when co-digested with other biomasses or wastes, WH either increases the process rate or improves the methane yield content. Also, the potential of WH as a phytoremdiator-cum-biogas source was investigated. This chapter provides mathematical models, scale-up installation models, and specific experimental results from various studies to guide future study plans toward optimizing CH4 generation from WH co-digestion.

The present work has assessed sustainable vermiconversion of aquatic weed water hyacinth (Eichornia crassipes). The garden soil, water hyacinth and cow dung were taken in the following the combinations of 1: 2 : 1, 2: 1: 1 and 1 : 1: 2. Two species of earthworms Eudrilus eugeniae and Eisenia fetida was used for the experiment. The total nitrogen (0.18% in control and 1.68% in earthworm treated) and phosphate (0.63 % in control and 1.64 % in earthworm treated) levels were increased and toxic heavy metals zinc (7.66 ppm in control and 2.58 ppm in earthworm treated) and copper (6.68 ppm in control and 1.15 ppm in earthworm treated) were significantly decreased. The earthworm enriches the compost with various nutrients for plant and microbial growth. Plant growth studies were conducted in all the combination of water hyacinth, maximum growth of root length (8.9cm and 7.2 in control) and shoot length (21.6cm and 16.2 in control) observed compare to control. Gut microbial analysis revealed that Bacillus cereus, Micrococcus luteus were predominantly present in the earthworm. The study recommended that the aquatic weed compost was suitable of agricultural usage.

Tendo em vista a utilização do aguapé como adubo verde foram feitas determinações de macronutrientes (N, P, K, Ca, Mg, S) e de micronutrientes (B, Cl, Co, Cu, Fe, Mn, Mo, Ni, Zn) nas raízes, caules e folhas de amostras colhidas na zona rural de Ourofino, MG. Verificou-se que 1kg da planta inteira possui as seguintes quantidades de nutrientes: N-10,3g, P-1,6, K-49,0, Ca-25,8, Mg-10,5 e S-3,3; B-25mg, C@-10436mg, Co-l,9mg, Cu-10,2mg, Fe-8969mg, Mn-1415mg, Mo-2,3mg, Ni-4,0mg e Zn-41,6mg. Fez-se uma comparação entre os nutrientes contidos no aguapé e no esterco de curral e discute-se o seu possível uso como adubo verde, fonte de matéria orgânica e de minerais.
