Abstract

The tidal land in Rawa Pening’s region is land that has been formed as caused of up and down water level process of Rawa Pening’s lake. The wide of tidal land that can be used are fluctuated beetwen dry and rainy seasons. The main used of tidal land is for rice field. The wide of tidal land that can be used for rice field beetwen elevation + 462,30 m and +463,30 m are 812 Ha, between elevation + 462,05 m and +462,30 are 218,51 Ha. There are some species of paddy that has been cultivated in that area, are IR-64, GH barito, ciliwung, cisadane, membramo and mentik. Mean of paddy yield is about 2,5 – 5 ton/ Ha.

Abstract

Eco – engineering without civil’s construction design for the Siak riverside’s protection can be applied at the part of river has riverside’s weak damaged. The riverside’s protection system with eco – engineering without civil’s construction as the effort to make stronger the riverside with vegetation components. The used of local vegetation is the best choice for eco – engineering system. The identification of vegetation on the Siak river’s corridor as long as desa Merempan Hilir to choose the plants to make the eco – engineering withoutcivil construction’s design has been done. Some kind of plants have been choosen i.e :rumput teki (Cyperus rotundus), rumput kumpai (Hymenachne acutigluma) rumput akar wangi (Vetiveria zizanioides), karangkunan (Ipomea carnea), bambu kuning (Bambusa vulgaris), pandan (Pandanus, sp), bintaro (Cerbera manghas), rengas (Gluta renghas),kempas (Koompassia malaccensis), jawi – jawi (Ficus, sp) and meranti (Shorea, sp).Key words : desain eko – engineering tanpa turap, perlindungan tebing, tanaman lokal

Abstract

Eceng gondok (Eichornia crassipes (Mart)(Solms) is a floating plants that creates problems on the maximum of waters utilization. On the other side, eceng gondok is a potential organic matter that can be used for a growing media. The utilization of the organic matter for growing media will support of organic farming and minimize the use of chemical materials. Process of eceng gondok decomposition can produce a growing media with high nutrients contain for plants growth. The experiments of growing media from eceng gondok for sawi hibrid plants show positive respons in which the plant has freshly growth and free of diseases.

Abstract

Tondano is a natural and biggest lake in North Sulawesi which some strategic functions i.e for irrigation, source of drinking water, hydropower, freshwater culture, tourisms, overflow control. Wide of Tondano Lake is about 46 – 51 km2. There are 35 streams as inlet and one outlet only is Tondano Stream. Tondano Lake has some problems caused by many activities both in downstream area or around of the lake. People’s activities such as land clearing for plantation in downstream area, freshwater cultureand daily people’s activities around of the lake had been organic material contribution in the lake waters. It has caused of water hyacinth booming (Eichornia crassipes (Malt) (Soms), erosion and sedimentation. Nowadays water hyacinth has been covered about 20% of Tondano Lake’s wide. Besides reduce of waters quality, water hyacinth booming has been made problems for hydropower and traffic in lake waters to the outlet. Because of that problems, Tondano Lake needs concern for intensif management.Key Words : strategic functions, ecosystem, erosion, sedimentation, water hyacinth.
