Abstract

Green belt is one of efforts in reducing urban air pollution level by planting trees along the road to absorbing pollutants. The purposes of this study are: (1) to know the Willingness to Pay (WTP) to reduce air pollution in Tarakan city, (2) to identify the factors that affect WTP. Locations of residential yard plantings are located on the roadside at the content exceeding the Threshold Limit Value. WTP method was used in calculating the community's willingness to pay for the planting of vegetation absorbs pollutant. The result of this research is that people are willing to pay (WTP) for IDR.7.325.98. The new prices are obtained by WTP is smaller than the current price set. And from the results of field's collected data there is only one variable that significantly affects the WTP of respondents, is the treatment cost.

Abstract

India and Indonesia are privileged with abundant biomass resource potentials, 23 Giga-watt (GW) and 50 GW equivalents respectively, yet both countries harvest small proportions, with fundamentally different deployed policies and articulated strategies. In this regard, this paper focuses on analyzing evolution and deployment of different policies and execution of strategies by two countries. It analyzes the effects of the biomass energy policies and executed strategies in India and Indonesia with a holistic approach. Such an approach takes the policy and strategy of the whole biomass energy sector rather than a segmented and separated sector as biofuel, biogas, biodiesel, etc. Furthermore, how they have resulted in different outcomes is also addressed. Our analysis shows that India's biomass energy policy has evolved from incremental to more radical changes, while Indonesia's policy remains incremental. India has also a relatively more unified biomass energy strategy than Indonesia. India has been more focused on technology development and deployment along with strong institutional creation, whereas Indonesia has not been able to create any biomass sector supporting strong institutions. Therefore, in terms of biomass energy utilizations, India has demonstrated better performance than Indonesia.

• New composite based on recycled LDPE and corn husk fibers has been prepared.

Abstract

Responding to the community demand for disposal of environmental problematic agricultural and polymer waste, composite sheets using recycled low-density polyethylene (R-LDPE) and corn husk fibers were prepared by melt compounding and compression molding. These composites were prepared in different concentrations (5, 10, 15, and 20%) of powder corn husk with 125 μ particle size based on R-LDPE matrix. Beside the importance of property improvement, an additional incentive was responding to the social demand for the disposal of environmental problematic agricultural waste. The influence of loading rate on R-LDPE crystallization behavior, mechanical, and swilling properties were investigated. Increasing in fiber loading led to increased moduli and tensile strength while hardness was decreased. X-ray diffraction (XRD) examinations indicated that introducing fiber to R-LDPE matrix did not change characteristic peak position. The thermal stability of the prepared composites was evaluated using differential scanning calorimetry (DSC) which displayed that the R-LDPE had significantly larger peak heat flow during cooling run than the blank R-LDPE, indicating higher crystallization rates for R-LDPE. The prepared composites materials can be used in packaging applications.
