AbstrakSemakin banyaknya pemukiman yang dibangun di bantaran sungai di Yogyakarta membuat sungai tercemar limbah rumah tangga. Penelitian ini bertujuan untuk mengetahui efektivitas tanaman eceng gondok (Eichhornia crassipes), genjer (Limnocharis flava), dan semanggi (Marsilea crenata) sebagai fitoremediator dengan wetland system dalam pengolahan air limbah domestik. Tahap pelaksanaan penelitian fitoremediasi diawali dengan pengukuran parameter air limbah yaitu pH, suhu, DO, BOD, dan TDS. Setelah itu, dilakukan aklimatisasi tanaman pada reaktor yang berisi air dan wetland selama 1 minggu. Terdapat empat perlakuan (P1, P2, P3, dan P4) yang digunakan, yaitu P1: air limbah + wetland (sebagai kontrol), P2: air limbah + wetland + 1 eceng gondok, P3: air limbah + wetland + 1 genjer, P4: air limbah + wetland + 1 semanggi. Terdapat 2x pengulangan selama masa retensi 12 hari, 2 variasi pengenceran yaitu 10x dan 100x. Hasil penelitian menunjukkan bahwa tanaman genjer mampu meningkatkan kadar DO sebesar 50% dan menurunkan kadar BOD sebesar 78%, serta tanaman semanggi mampu menurunkan kadar TDS sebesar 41,4%. Angka ini mencerminkan bahwa penggunaan tanaman-tanaman tersebut memiliki potensi besar dalam membantu pemurnian air.Abstract The increasing number of settlements built along the river banks in Yogyakarta resulted in household waste entering the river. This study aims at determining the effectiveness of water hyacinth (Eichhornia crassipes), genjer (Limnocharis flava), and clover (Marsilea crenata) as phytoremediators, in a wetland system. Firstly, wastewater parameters such as pH, temperature, DO, BOD, and TDS are measured. After that, plants were acclimatized in the reactors containing water and substrate derived from a wetland for 7 days. There were four treatments applied in this research (P1, P2, P3, and P4), P1: wastewater + wetland (as control), P2: wastewater + wetland + 1 water hyacinth, P3: wastewater + wetland + 1 genjer, P4: wetland water + wetland + 1 clover. Each treatment was replicated twice during the 12 days retention period, and 2 variations of dilution of 10x and 100x. The results indicated that genjer plant was capable of increasing the DO level by 50% and lowering the BOD level by 78%, and the clover plant was able to decrease the TDS level by 41.4%. Those results reveal that the use of the plants has huge potential in helping water purification.

The Relationship

Water hyacinth (Eichhornia crassipes (Mart.) Solms) grows very vigorously and has a high content of nutrients. Cultivation experiments were conducted on water hyacinth to check whether it is worth using for water purification and to obtain guiding principles for the practical use of water hyacinth grown in natural water channels or ponds. The average dry weight, nitrogen and phosphate content in the biomass were 5.0%, 2.5% and 0.57%, respectively. The growth rate of the water hyacinth was higher from May to June than in other seasons. The logarithmic regression equation between the growth rate (Y) and solar radiation (X) was expressed by Ln (Y) = 0.0042X-4.92 with a coefficient of correlation of 0.768. The relationship between the concentration of nutrients in water (X) and in water hyacinth (Y) is expressed by Y = Cmax.X/(Ks+X). The relationship between the relative growth rate and the concentration of nutrients was also expressed by the same type of equation. The relationship between a harvesting interval and the total yield of the water hyacinth within a given period was expressed by a mathematical model. It was made clear from the model that the shorter the harvesting interval was, the more the total yield of the crop increased.

Ground water in general is clean and fresh. However, industrialization and urbanization together with intensified agricultural activity have led to increasing demands on one hand but to the potential for large scale release of contaminants on the other. Water pollution disturbs the normal uses of water for agriculture, public water supply, aquatic life, wild life and industry. An understanding of the various types of pollutants is of considerable importance to the efficient management of water resources. Inorganic pollutants discharged into natural waters consist of mineral acids, inorganic salts, metal compounds, complexes of metal and trace elements. The proposed investigation will evaluate the underground water quality of hand pump water and Tap water of Sirgitti in rural area and its surrounding industrial areas near 7 km from Bilaspur C.G. With this objective in mind, A new and low-cost technology for purification for water by water hyacinth (Eichhornia crassipes), is a feasible solution. Water samples were collected during the growth of water hyacinth. Water purification with low-cost treatment technology using water hyacinth. The common Water Hyacinth is vigorous growers known to double its population in only 12 to 15 days. In the Water Hyacinth area and the nearby area, water pH showed a decrease between the August and September sampling followed by an upward trend and stayed stable around 9.3 in the far water hyacinth area. Water transparency showed a slow increase in August and September, and then a gradual decline in October; generally, transparency was significantly lower in the water hyacinth area than in other areas. Water Hyacinth has been used in aquatic systems worldwide for waste water purification. It has tremendous capacity of absorbing nutrients and other substances from the water and hence brings the pollution load down. In the present study an attempt was made to find the potential of Water Hyacinth in the treatment of Tap and hand pump water near industrial area of Sirgitti. The parameters studied were pH, EC, DO, BOD, TDS, Salinity, Alkalinity and Turbidity. Six months of experimental investigation showed that water hyacinth reduced considerably all the physicochemical parameters and but increased the Dissolved Oxygen (DO) to a significant level therefore it is concluded that Water Hyacinth (Eichhornia crassipes) is highly efficient in purification of water in respect of physicochemical parameters.

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
