Abstract

Indonesia has a vast forest area. The extent of Indonesia's forests is one of the natural resources are prone to damage due to human interests in meeting their needs. One of the damage that often occurs when current is forest fires. Forest destruction accounts for 20-25% of global CO2 emissions that contribute to climate change or global warming. Unspoiled forest with a diversity of plant species are long-lived and litter is a place to store a lot of carbon stocks (C) the highest. The aim of this study was to determine the diversity of plants and the amount of carbon stock above ground level in the forests of the Bukit Barisan of Padang, West Sumatra. Tree biomass was calculated on a plot of 20x20 m, 10x10 m pole, stake 5x5 m, for counting down plant biomass and litter on the plot with a size of 2x2 m (National Standardization Agency, 2011). Biomass calculated by the Ketterings et al. formula (2001). In Bukit Barisan Forest Area, West Sumatra, derived carbon content was 16.029,70 ton/ha. Diversity type was highest at tree level on Station 1, classified as very high diversty with diversity index (H’) 3.10.

Abstract

Recently, climate change is the one of most important environmental issue. Climate variability can be recorded by tree growing through the growth ring. Growth ring formed by cambial activity were examined in wood anatomy. In Sumatra, there are three ecotypes Pinus merkusii, namely ecotypes Kerinci, Tapanuli, and Aceh which can be distinguished morphologically. This study aims to knowing the wood anatomical characteristics of the three ecotypes and determine the potential as climate indicator. This study was conducted in October 2014 until June 2015. Sample of Kerinci ecotype was collected in Kerinci Seblat National Park, Tapanuli ecotype in Dolok Sibualbuali Natural Reserve and Aceh ecotype in Gunung Leuser National Park on a height of 130 cm using increment borer and cut on the main stem 5×5 cm for anatomical sample. Results from this study indicate that ecotype Kerinci and Tapanuli showed earlywood and latewood boundary exposing the clear growth ring, whereas in Aceh ecotype unclear. Tapanuli ecotype have the thickest tracheid diameter than ecotype Kerinci and Aceh. Ecotypes of Kerinci, Tapanuli, and Aceh has homoceluler and uniseriate ray where Aceh ecotype have the longest ray. Furthermore, Kerinci and Tapanuli ecotype have potential as climate indicator eventhough showed negative correlation, that Tapanuli ecotype show the best result and recommended in dendrochronology study.

Abstract

Growth ring trees are formed by activity of the cambium which is influenced by the changing seasons.   In the tropical are not all of  trees species produce  the growth ring, because the season of  tropics is more uniform throughout the year and does not show sharp distinction between the periods of high rainfall and period of low rainfall. This study has concentred on several tree forest areas in Siberut National Park, Mentawai Islands. Samples were ollected by using borer on the main stem on the height of 130 cm. To see or not to see growing circle with to be checked macroscopically and microscopically. The macroscopic examination was done polished core by several grades of sandpaper in the transverse surface Tree species which have growth ring continued to microscopic observation with making slice anatomy. Based on 46 species of trees were examined, and  6 species were with found a growth ring in the number of cell mixture early wood and late wood from these species.

Abstract

Hutan Tropik memiliki sumber cadangan karbon sangat besar yang dapat berubah akibat perubahan kondisi hutan yang disebabkan oleh aktivitas  manusia, termasuk penebangan dan perkebunan sehingga mengancam perubahan iklim dunia. Kajian analisis dilakukan untuk menetahu struktur vegetasi dan kandungan karbon pada tiga kondisi hutan di Pulau Siberut sebagai upaya mitigasi perubahan iklim. Untuk mendapatkan data biomassa bagian atas tanah dan serasah digunakan metode plot berpetak.  Hasil Penelitian didapatkan 38 spesies dan 122 individu tumbuhan pada hutan primer, 22 spesies dan 49 individu pada hutan bekas tebangan serta 45 spesies dan 120 individu pada hutan tanaman campuran. Kandungan karbon bagian atas tumbuhan hidup pada hutan primer 1.359.884,68 kg/ha, hutan bekas tebangan 610.429,67 kg/ha  dan hutan tanaman campuran 360.793,70 kg/ha.  Kandungan karbon pada serasah hutan primer 774,49 kg/ha, hutan bekas tebangan 521,36 kg/ha dan hutan tanaman campuran 766,20 kg/ha.

Abstract

The study about leaf anatomy of Bilberry (Vaccinium korinchense RILD.) at altitude gradient on the Talang Mountain has been carried out in October to December 2015. The goal research is to compared that leaf thick tissues Bilbellry at altitude gradient. The sample were collected at Talang Mountain. The research used survey method and purpossive sampling with five altitude gradient (2200-2529 meter above sea level). Leaf section was maked at the Plant Structures developments Laboratory, Department Biology, Faculty of Mathematics and Natural Sciences, Andalas University. Data analysis used Kruskal-Wallis test. The results showed that leaf thickness, palisade and spongy thickness various between altitudes is sequentially 434-685 ?m, 183-322 ?m and 175-283 ?m . While epidermis thickness and cuticle thickness did not differ significantly between altitudes.
