Abstract

The increasing of human’s activities caused the pollution load going up. It affected the amount of the Winongo River’s capacity. One of the river management attempts was find out the amount of the capacity with a modeling method. The modeling program in this research was Qual2Kw. The research method was supported by the secondary and primary data treated by the Qual2Kw program. This research was divided in three scenarios. The trial results showed that the BOD concentration in the along of the river was 16 mg/L, the DO concentration was 2.4 mg/L, 7 of pH, and 26oC of temperature. The condition of BOD from the upstream to the downstream in the existing condition had exceeded the quality standards, 3 mg/L. The attempts to decrease the pollution load capacity of Winongo River by 2012 was decreasing the pollution load from the point source 959.25 kg/day and from the diffuser source was 193.75 kg/day. The another effort was making the IPAL Komunal in each sub-districts. Keywords: Winongo River, capacity, Qual2Kw

Abstract

Waste management in particular catalyst waste of oil cracking industry has been many proposed by land disposal, but waste management by all at once reuse still be increased. This research are laboratory scale and application activity by make concrete roof-tile. The concrete roof-tile materials are used portland cement, fine coarse (sand), mill, and catalyst waste. The using of catalyst asadditif materials with compotition 0 %, 10%, 20 %, 30%, 40 %, 60 %, 80 %, and 50 %. The result of testing shown bending strength at 10 %, 20%, and 30% of catalyst waste are more than the normal concrete roof-tile ( 0% waste). That are 1,20, 12,33, and 11,00 kg/cm2 for10%, 20 %, 30%, % waste at the time that bending strength of normal concrete roof-tile is 10.97 kg/cm2. Testing of permebility shown that all of the sample are impermeable of water. The leaching experiment of heavy metal Cr, Pb, Zn, Ni and Cu on monolite matrix (concrete roof) by Toxicity Characteristic Leaching Procedure (TCLP) shows that the leaching of heavy metal is under standard. The greater leaching is Ni, that is 1,179 mg/L for 50% proportion of waste.

Abstract

Waste management is one of the criteria for the evaluation of Green campus and sustainable university. Organic waste takes place in concern because of the domination of waste in university, such as food waste and dry leaves waste. Mismanagement in dry leaves will promote the campus area to look dirty. One method to control the dry leaves waste is the vermicomposting process. The purpose of this research is to evaluate the macronutrient content of dry leaves compost after the vermicomposting process. The research was conducted in the Faculty of Civil engineering and Planning, Universitas Islam Indonesia, Yogyakarta. The vermicompost sample in this study refers to the quality standards according to SNI 19-7030-2004 regarding compost quality standards. The results of vermicompost content value are obtained on day 56 is Phosphor amounting to 0.194%, amounting to 0.129% Potassium, and C / N ratio of 7.73. From the data that has been obtained can be concluded that the results of vermicompost are less effective as organic compost compared to the standards.
