Water Weed

Water hyacinth is the world's worst water weed that is responsible for many environmental and economical problems. Nigerian fresh waters have been infested with this aquatic weed. In this work, a Natural Convection Mixed Mode Solar Dryer for drying water hyacinth to about 10% of its moisture content was constructed and tested as a component of controlling its infestation of the River Benue. The performance of the dryer was compared with the traditional open–air sun drying as the control for drying water hyacinth in Makurdi, Benue State Nigeria. The water hyacinth was dried for 8 hours each day for 4 days. 500g of water hyacinth on wet basis was dehydrated by about 437g on dry basis in 20 hours in the dryer while the control required 32 hours. The dryer was found to be technically more suitable for drying water hyacinth both in terms of the drying rate and quality of the dried product.

Industry Wastewater

In the processing of chips using cassava (Manihot utilissima), it will produce waste in the form of solid and liquid waste. The liquid waste of processing cassava chips contains organic compounds that are easily decomposed and cause unpleasant odors. If the liquid waste is discharged directly into the environment, it will cause pollution and damage the environment. One of the steps that can be used to overcome this problem is phytoremediation. The purpose of this study was to determine the best treatment in the processing of cassava chips industrial wastewater so that the liquid waste is safe to dispose of into the environment. In this study, using two types of aquatic plants, namely water hyacinth (Eichhornia crassipes) and kiambang (Pistia stratiotes) and using alum to remediate liquid waste. This research was conducted experimentally using a jar with a diameter of 15 cm and a height of 25 cm with 3 repetitions of each treatment. The data obtained were analyzed descriptively to determine the best treatment that can be used for remediation of cassava chips industry wastewater. The results showed that the use of water hyacinth plants (Eichhornia crassipes) could improve the quality of wastewater so that it is safe to dispose of into the environment.

Negative Impacts

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.
