Abstract

The research was conducted about dirt pig compost with variation of composition, Toksicity of it was detected by influence to Growth Of Lombok Rawit ( Capsicum Frutescens). The composition of it is I ( pig dirt 40%, hay 40%, dregs know 18%, dolomit 20%), II ( pig dirt 60%, hay 22%, dregs know 13%, dolomit 2%), and III ( pig dirt 70%, hay 13%, dregs know 15%, dolomit 2%). Growth of microorganism in compost process cover two phase that is ferment phase and maturation Process of composting with composition of III ( pig dirt 70%, hay 13%, dregs know 15%, dolomit 2%) owning best quality. That shown from speed of maturation time posed at stability of temperature and pH reached at period six week, influence to growth of lombok rawit ( Capsicum Frutescens) tried give best level of growth that seen amount of leaf more than composition I and II.

Abstract

The capability of sandstone coated with Fe2O3 as adsorbent to reduce lead (Pb) content in solution has been stadied in this research. The adsorption process of Pb in solution by sandstone was carried out by immersing sandstone (uncoated A0) in Pb(NO3)2. Coating sandstone was done using Fe(NO3)3.9 H2O with different concentration as follows : 10 g (A1), 20 g (A2) and 30 g (A3) in 50 ml aquadest. To find out the optimum concentration of Fe(NO3)3 as coating agent. The adsorption process of coated sandstone was done by immersing them in Pb(NO3)2 solution. To determine the time of optimum adsorption, the sandstone (coated and uncoated) were immersed for a period of their equilibrium adsorption time. The absorbance of the filtrat resulted from adsorption process was determined by atomic absorption spectrophotometer at ? 217 nm. The result showed that optimum concentration of Fe(NO3)3 as coating agent was 20 g (A2) with the capability absorbing lead (Pb) 4.653 mg/g. The capability of A3 as adsorbent was 4.644 mg/g and the capability of A1 was 4.529 mg/g while the capability uncoated sandstone as adsorbent was 2.784 mg/g.

Abstract

This research was conducted to study the potential of the plants ‘useless’ as kiambang(Salvinia natans) which are easy to find, and not as valuable as textile dyeing waste handlingmedia. Treatment technique used is to replace the growth medium with the waste in questionin this case of waste taken in the dyeing industry. The concentration of methylene blueinwaste of  dye, and congo red, before and after treatment, determined by spectrophotometry.Fluid absorbance was measured at a wavelength of 664 nm for methylene blue and 496 nmfor congo red. Long time treatment used is 6, 12, 18, 24, 30, 36, and 48 hours. These resultsindicate that kiambang (Salvinia natans) is useful to lower BOD and COD of waste dyeing,although its ability to reduce the content of the dye congo red and blue methyl insignificant.This may be caused by too concentrated the dyeing waste.

Abstract

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).
