Abstract

Order to determine the development of oil palm expansion in Rokan Hilir and to determine the influence of the expansion of oil palm plantations on the ability of carbon sequestration in Rokan Hilir. The method of analysis used in this study is descriptive qualitative method using the geometric mean. From the results of research on secondary data obtained, indicating the growth of oil palm land area affect forest area, based on the results of the calculation, oil palm plantations grew by 7.17%. Where in 2008 the garden area of 205,537 acres of oil palm, and then increased in 2013 to 271,169.02 acres, while the forest area shrank by 17.6%, whereas in the year 2009 forest area amounted to 683.070 acres, then in 2013 only amounted to 314,229 acres. It also effects the ability of carbon sequestration in forest areas, the ability of forest to absorb carbon decreases as the extent of diminishing returns and has been replaced by oil palm plantations, while the absorption ability of oil palm plantations are not forest's ability to absorb carbon. The ability of forests to absorb carbon in the year 2008 amounted to 52,185,760.42 mg / acres, while in 2013 only amounted to 24,006,733.29 mg / acres, so that carbon stocks were lost due to the development of oil palm expansion of 25744582.5 mg / acres.Keywords: forestry, oil palm plantation, carbon sequestration

Abstract

Jambu air cincalo memiliki aktivitas respirasi non-klimakterik dengan kadar air yang tinggi, sehingga penanganan pascapanen yang tidak tepat akan memicu pertumbuhan cendawan. Penelitian ini bertujuan untuk mengetahui pengaruh edible coating dari oleoresin daun kemangi dan menentukan konsentrasi yang tepat untuk memperpanjang umur simpan buah jambu air cincalo. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal, terdapat 4 perlakuan yang merupakan jenis konsentrasi oleoresin daun kemangi yang terdiri dari K0 (tanpa penambahan oleoresin), K1 (0,3% oleoresin), K2 (0,6% oleoresin) dan K3 (0,9% oleoresin) dengan 3 ulangan. Peubah yang diamati adalah susut bobot, total padatan terlarut, total asam buah, kandungan vitamin C dan organoleptik. Hasil penelitian menunjukkan bahwa perlakuan konsentrasi oleoresin daun kemangi berpengaruh tidak nyata terhadap peubah yang diamati, meliputi susut bobot, total padatan terlarut, total asam buah, dan kandungan vitamin C. Semua perlakuan dengan penambahan oleoresin maupun tanpa penambahan oleoresin daun kemangi cenderung memberikan hasil yang sama terhadap buah jambu cincalo.
