Abstract

Pengkajian terhadap kesanggupan membayar masyarakat willingness to pay (WTP) bagi peningkatan kualitas udara disekitar ruas jalan dengan metoda langsung (Contingent Valuation Methode). Pengambilan sampel bersifat acak sejumlah 892 responden terdiri dari 446 responden masyarakat dan 446 pemerhati lingkungan. Data diolah secara statistik dan WTP yang diperoleh untuk peningkatan kualitas udara 25% dan 50% untuk kelompok masyarakat adalah Rp. 13,225,- dan Rp. 15.290,- , untuk kelompok pemerhati lingkungan Rp. 21.280,- dan Rp. 23.105,-. Evaluasi besaran manfaat untuk ruas jalan kajian dengan dimensi panjang jalan 1 km dan jarak 100 meter ke dalam dari tepi jalan diperoleh manfaat berkisar Rp. 5.950.125,- dan Rp. 6.880.500,-.

Abstract

Abstract Result of air quality at road sides for Nox, SO2, O3, CO and SPM10, were still below ambient quality standard, with the average from morning till afternoon were NOx : 0,0127 ppm, SO2: 0,0251 ppm, O3 : 0,0535 ppm, CO: 0,0610 ppm, and SPM10: 54,4 ug/M3. The average hydrocarbon was more than air quality standard. The result of evaluation with ISPU on busy time where was classified as medium which was cause by the SPM10. Meanwhile, average lead (Pb) contain in tea leaf was 5,00 ppm in dry plant.

Abstract

Erosion is really a problem in slope areas where the length andinclination of slope influence surface flow and erosion. Double increase of flow in speed leads to the increase of eroding granular soil up to thirty-two fold. When the length of slope is two-fold, the erosion will be 1.5 times. Research result in Indonesia indicated that the degree of erosion in deforested lands reached 120-400 tonnes/ha/year. Such case will obviously give negative impact on road drainage system. Therefore, erosion control technology in roadside slopes should be developed. The purpose of the research is to find out the influence of slope inclination and vegetation on the degree of erosion at the inclination either above or under 60â—¦. Furthermore, erosion control technology is also discussed. To achieved the purpose, the research was done and laboratory prototype of erosion control with vegetation was made. Field research of erosion control technology using vetiver grass combined with bahia grass was carried out. Research showed that the degree of plant lushness and the lushness of slope cover, by covering > 70% of slope, eroding land is almost zero. Planting of vetiver will effectively reduce the degree of erosion when it is planted in lines and bahia grass is planted in between. Key word : control soil erosion, vegetasi, vetiver grass

Abstract

Development of urban traffic volume has reached 15% per year. Transportation is a mayor cause of air pollution, 70% of air pollution is generated from vehicle exhausts. Air pollution parameters from motor vehicles such as carbon monox ide (CO), Nitrogen oxide (NOX), Methane (CH4), Non Methane (NonCH 4), Sulfur dioxide (SOx) and Paticulate (SPM 10) contribute heavily to global warming. Monitoring result of air pollution in urban roads such as Surakarta, Yogyakarta, Semarang, Surabaya, Denpasar (Bali), and Serang (Banten), and other cities passed by North Coast Road links showed that the air quality in this area nearly the limit line or standard air quality ambient especially Nitrogen oxide (NOx), suspended particulate matter (SPM10) and hydrocarbon (HC). The range of air quality ambient for CH 4 : 1,0 – 1,97 ppm, NonCH4 : 1,5 – 3,78 ppm, NOx: 0,06 – 0,490 ppm, SOx: 0,001 – 0,276 ppm, CO : 0,01 -11,53 ppm and particulate (SPM 10): 6,0 – 260 ug/m3. According to Ministerial decree of Environment no. 45/1997. monitoring result with air pollution index (ISPU) showed that the condition was categorized “moderate” which mean the air quality will not affect on human health or animals, but can damage plants and aesthetics-value. Some correctives and measures to minimize air pollution are as follow : a.Consideration and application policy with environment regulations become important steps to the whole cycle road-projects. b.Social participation in environmen tal management as vehicle owners,road user and community of road environment. c. utilization of and environmental fuel and vehicles. d. The application of air pollution reduction technology such as landscape arrangement by restoration of vegetation. Key words : air pollution, vehicle, urban

Abstract

General condition network of national roads in 2005 indicated 11% (3.809 Km), their condition were heavily damage, 8% (2.770 Km) light damage, about 81% (20.050 Km) in good condition. The increased damage of roads is caused by some factors: specification of construction is not appropriate and supervisor or implementer is not professional and nature disaster etc. But environmental factor often is forgotten. Studying of environment for building and increasing of roads based on Kepmen Lingkungan Hidup No. 17/2001 and Kepmen Kimpraswil No.17/2003 it’s clear, it must be equipped with AMDAL or UKL/UPL but the documents in realization are not benefit so that it is ignored and never to make survey too. Result of studying for some documents AMDAL or UKL/UPL inroads sector, damaged roads will not increase if the document are arranged professionally and responsibility, user has to do the suggestion in document. Technical studying of environment needs to the attention for increasing the roads plan age are tophographie data, soil data, social-economic survey, hydrology data (drainage system) and vegetation condition around the project area, including in environment control plan. That control on decrase road damage about 5-20%. Keywords : Environmental Control, Roads Contraction
