ABSTRAKSecara ekologis, Danau Rawa Pening kondisinya telah banyak mengalami perubahan yang diindikasikan oleh tidak terkontrolnya pertumbuhan tanaman akuatik seperti eceng gondok yang umumnya berkaitan dengan proses eutrofikasi. Tujuan dari penelitian untuk mengetahui kualitas perairan berdasarkan struktur komunitas plankton pada perairan yang ditumbuhi eceng gondok di Rawa Pening. Penelitian ini dilaksanakan pada bulan Oktober sampai November 2016. Metode yang digunakan adalah observatif dan pengambilan teknik sampling secara purposif dan uji laboratorium. Lokasi pengambilan sampel yaitu stasiun 1 merupakan daerah yang terdapat eceng gondok cukup tinggi (kerapatan tinggi dengan persentase berkisar >70-100%). Stasiun 2 merupakan daerah yang terdapat eceng gondok relatif sedang (kerapatan sedang dengan persentase berkisar 40-70%). Stasiun 3 merupakan daerah yang terdapat eceng gondok relatif rendah (kerapatan rendah dengan persentase berkisar <40%) serta stasiun 4 merupakan daerah yang tidak terdapat eceng gondok. Hasil penelitian menunjukkan bahwa kelimpahan Fitoplankton berkisar 620-15690 Ind/L. Jenis Fitoplankton yang ditemukan terdiri dari 4 kelas yaitu Chlorophyceae, Bacillariophyceae, Cyanophyceae , Xanthophyceae. Kelimpahan Zooplankton berkisar 620-1608 Ind/m3. Jenis Zooplankton yang ditemukan terdiri dari 5 kelas yaitu  Zoomastigopora, Pytomastigopora, Euglenaphyceae, Rotiferaceae Ciliata, Crustacea. Kualitas perairan di Danau Rawa Pening masih pada batas-batas yang layak untuk kehidupan plankton.Kata Kunci: Plankton, Eceng Gondok, Danau Rawa Pening.  ABSTRACT                Ecologically, Lake Rawa Pening has been extensively amended condition indicated by the uncontrolled growth of aquatic plants such as water hyacinth which is generally related to the process of eutrophication. The goal of the research is to find out the quality of the waters of the plankton community structure based on waters covered by water hyacinth in the Lake Rawa Pening. This research was carried out in Oktober and November 2016.  The method used is observatif field and taking of sampling in purposive and laboratory. The location of sampling is divided into four stations and each station is divided into two points. Station 1 is that there is water hyacinth is quite high (high density with a percentage ranging <70-100%). Station 2 is the area contained relatively water hyacinth are medium density (percentage of 40-70%). Station 3 is the station contained water hyacinth is relatively low (low density with a percentage ranging from 40%) as well as station 4 is there is no water hyacinth. The results showed that Phytoplankton abundance range 620-15690 Ind/L.  Types of Phytoplankton found consists of 4 classes namely Chlorophyceae, Cyanophyceae, Bacillariophyceae, Xanthophyceae. The abundance of Zooplankton range 620-1608 Ind/m3. Types of  Zooplankton found consists of 5 classes, namely Zoomastigopora, Pytomastigopora, Euglenaphyceae, Rotiferaceae Ciliata, Crustacea. The quality of the waters of Lake Rawa Pening is still within the limits that are reasonable for the life of the plankton. Saprobik index (SI) of 2 and the value of Tropical Saprobik Index (TSI) of 1,33 this indicated that these waters are in a phase of Oligosaprobik toward β-mesosaprobik.. Keywords: Plankton, Eichhornia crassipes, Lake Rawa Pening.

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.

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.
