Abstract

Forest has an opponent function in climate change issue, as carbon sink and carbon source. Reducing emission from deforestation and forest degradation (REDD) is the mechanism to tackle green house gas emission from forest sector. The economic analysis of those projects in Indonesia has not conducted yet, moreover the benefit and cost analysis of REDD on forest management unit. The research was conducted in the unique site, at Industrial Forest Plantation PT. SBA WI, South Sumatera. Benefit and cost analysis and break-even cost analysis were conducted to evaluate project feasibility. The research result shows that forest management was not feasible if the role of the project aimed to product wood or reducing emission only which conducted in mutual. If the project aims to reach both roles together, it is very attractive. Break-even cost of reducing emission and carbon sequestration in PT. SBA WI Rp.29.000,- per ton CO2e equal to US$3,17. It was lower than the cost in Bolivia, Ghana, and Nepal and also cheaper than carbon price in voluntary market.

Abstract

Peningkatan CO2 di atmosfer yang berpotensi menghasilkan pemanasan global telah menjadi perhatian bagi kehidupan manusia. Lautan mengandung lima puluh kali lebih besar CO2 daripada atmosfer dan menjadi penyangga yang membatasi konsentrasi CO2 dalam atmosfer. CO2 mengalami perubahan secara terus menerus antara udara-lautan dan konsentrasi CO2 di dalam laut dikendalikan oleh parameter fisika, kimia, dan biologi. Perubahan konsentrasi CO2 antara udara-lautan dapat ditentukan dari interaksi gas dan perbedaan konsentrasi CO2 antara udara-lautan. Perubahan CO2 antara udara-lautan dapat dikaji dari studi kecepatan angin, koefisien gesekan kecepatan angin yang diperoleh dari satelit ALOS/PALSAR di daerah Selat Badung dan Selat Lombok, salinitas, dan juga dengan SST yang diperoleh dari satelit MODIS. Hasil analisis menunjukkan bahwa koefisien perubahan CO2, perbedaan tekanan CO2 antara udara-lautan, dan CO2 flux antara udara-lautan secara berturut-turut yaitu 0.303±0.006 (rata-rata±standar deviasi) (mol m-2 month-1µatm-1), 17.94±10.79 ?atm, and 5.35±3.26 (mol m-2 month-1), dengan nilai maksimum dan minimum dari koefisien perubahan CO2 secara berturut-turut terjadi pada bulan Agustus dan Februari.

Abstract

Studi ini meneliti pengaruh faktor-faktor lalu lintas lokal terhadap tingkat kebisingan di jalan arteri di Bali dengan studi kasus jalan Bypass I Gusti Ngurah Rai dan Sunset Road. Model regresi sederhana dan regresi berganda disusun dengan variabel-variabel volume dan kecepatan lalu lintas serta nilai kebisingan yang diperoleh dari hasil pengukuran tingkat kebisingan di kedua jalan arteri tersebut. Model yang disusun terdiri dari 1 variabel tidak bebas dan 8 variabel bebas menggunakan perangkat lunak SPSS versi 15. Hasil studi ini menyimpulkan bahwa volume lalu lintas dari sepeda motor dan jarak pengamatan kebisingan dari garis tengah jalan terdekat sangat berpengaruh terhadap tingkat kebisingan. Volume sepeda motor berpengaruh sebesar 26.7% terhadap tingkat kebisingan dan gabungan volume sepeda motor dan jarak pengamatan kebisingan dari garis tengah jalan terdekat berpengaruh sebesar 46.9% terhadap tingkat kebisingan. Semakin besar volume lalu lintas dari sepeda motor semakin tinggi pula tingkat kebisingan. Kebijakan di bidang transportasi seperti pengurangan jumlah sepeda motor di jalan raya dan pada saat yang bersamaan memperbaiki kualitas angkutan umum merupakan alternatif untuk mengurangi tingkat kebisingan. Penelitian ini juga menyarankan suatu studi lanjutan untuk menentukan jarak pengamatan yang ideal dari garis tengah jalan pada saat pengukuran tingkat kebisingan di jalan.

Abstract

Research concerning of propagation of a wild-extinct fern Lygodium circinnatum had been done at Faculty of Agriculture, Udayana University, Denpasar Bali Indonesia. At some places in Indonesia, as well as Bali, this species is used as materials for making handicraft. In Bali, the species grows wildly in the forest and it is almost extinct due to over gathering. This study aimed to find out method for domestication of L. circinnatum, therefore this wild species can be cultivated, provided materials for making handicraft and might solve the problem of extinction. Various media for growing spores of L. circinnatum in vitro and ex vitro were trialed. In conclusion, full strength of MS media without sugar was the most appropriate media for growth and development of spores of L. circinnatum in vitro. While for ex vitro, the appropriate media were paddy silt-soil and decomposed leaf either with or without addition of foliar fertilizer. However, we suggested ex-vitro cultivation was more appropriate, the technique was much easier and the spores grew faster compared to those of in-vitro.
