Abstract

The purpose of this research was to see the opportunity of palm oil waste water utilization forreplacing anorganic fertilizer in growing crops. This research was using complete randomdesign in factorial design experiment using 12 kilograms of Podsolik that is mixed and filledin 40 x 40 centimeters plastic bags. Treatment that is used in this research was using wastewater Biological Oxygen Demand (BOD5) concentration (1000, 3000, 5000 and 7000)milligram per liter and urea fertilizer with dosage (0, 1, 2 and 3) gram and each treatmentwas three times replicated. The research was starting from February 28, 2010 to May 9,2010.Palm oil waste water that was used in this research gave significant difference result.Test result gave different result at all levels of waste water concentration except atconcentration of 3000 mg/l with 1000 mg/l. Interaction between treatment given was testedwith Duncan method and indicated that optimum dosage that can be used was 0 gram ofUrea fertilizer combained with waste water with BOD5 concentration 7000 mg/l.Utilizationof palm oil mill’s waste water with dosage 375 ml for 8 weeks after planting period orequivalent with 3 liters was not able to give crop result as good as comparison plant that isplanted, but waste water utilization to grow crop give good growth responses especially inmaize (Zea mays L.) that is tested. Utilization of palm oil’s waste water was suitable forbiomass production purposes but not for crop results. Utilization of palm oil mill’s wastewater especially in palm oil mill that has no plantation become one of solutions and efforts inreducing potential environmental damage caused by palm oil mill’s waste water, especiallywater and waterworks pollutions . It could be happen since waste water was not thrown awayto river but utilized to grow crops.

Abstract

Malaria is a disease caused by Plasmodium parasites. Year 2007 people infected with malaria District Sungai Mandau 57.37 per 1000 population. This study aims to determine ecological factors that affect the habitat of the Anopheles mosquito larvae in the village of Muara Kelantan District Sungai Mandau, Siak Regency in 2009. Depth of water, water flow, mud bottom, thecolor of brown waters, and temperature, salinity, pH water,and humidity on the waters in the village of Muara Kelantan suited for the life of the larvae of Anopheles spp. This is supported bythe density of mosquito larvae of Anopheles spp calm in the gutter, the gutter flow and swampland in succession 0,006 ind/ml, 0,078 ind/ml, and 0,004 ind/ml respectively.
