Abstract

Tree growth is closely related to the process of photosynthesis. So far the rate of photosynthesis in elements of secondary forests has not been known, especially in pioneer species. At the same height of the place and micro-climate conditions, the rate of photosynthesis of pioneer species of secondary forest has a different rate of photosynthesis. This study aims to determine the ability of the rate of photosynthesis of some secondary forest pioneer tree species in order to support reforestation efforts on degraded forests and at the same time looking for the kinds of pioneers who have a high absorption of CO2 gas in an effort to reduce global warming caused by emissions CO2 gas in the air. The survey results noted there are 6 common pioneer tree species grow at the sites. Trema orientalis had the highest CO2 assimilation value which is equal to 20,350 μmol m-2s-1, followed by the Macaranga triloba (17,198 μmol m-2s-1), Omalanthus populneus (14,097 μmol m-2s-1), Mallotus paniculatus (13,118 μmol m-2s-1), Macaranga tanarius (12,862 μmol m-2s-1) and Weinmannia blumei (10,058 μmol m-2s-1). Research conducted during the rainy season (September 2010). During measurement, the light radiation in the upper leaf surface between 63,583 to 363,750 μmol m-2s-1, air temperature 21,8 to 26,70C, air humidity 75,8-89,8%, light intensity 2483,3 to 28701,7 Lux, soil pH 5,8 to 6,3 and soil moisture between 50,7 to 71,7%.

Abstract

Leaf NPK fertilizer experiments on pitcher plant (Nepenthes neglecta and ventrata) conducted in May 2008 to March 2009 in a greenhouse, Botany Division, Research Center for Biology-LIPI, Cibinong Science Center, Cibinong. The objective is to study the effect of leaves NPK fertilizer on the growth of the two Nepenthes species tested. Experiments using Random Complete Factorial Design with two factors, namely the two Nepenthes species and threedoses of fertilizer each treatment repeated six times. Growth parameters measured include; long shoot leaves, plant height, number of leaves, number of mature pitchers and growth pitchers. Results showed that the dose of NPK fertilizer provided (2 and 4 ml / lt) have no effect on plant height and number of leaves, but little effect on the number of mature pitchers thanthe control plants. The statistical tests also showed no interaction between the two Nepenthes species with a given dose of fertilizer on the growth of plants. Minimum-maximum temperature recorded in the greenhouse during the experiment was 22.20C and 38.50C. Meanwhile, air humidity between 43,6-64,7%.Key words: Leaf NPK fertilizer, plant growth, pitcher plant

Studi potensi serapan Karbondioksida (CO2) pada beberapa jenis pohon tumbuh cepat dilakukandi hutan rawa gambut, Hampangen, Kalimantan Tengah, pada bulan September, 2012. Sebanyakdelapan belas individu dari enam jenis pohon dipilih sebagai sampel pengukuran. Setiap individudiukur daun muda dan daun tua. Laju serapan CO2 dan parameter fisiologi lainnya diukur denganalat portable Lci ADC Bioscientific Ltd. Photosynthesis system, kandungan khlorofil daun denganalat Chlorophyll meter tipe SPAD-502 merk Minolta, Intensitas cahaya dengan alat Lux meter,suhu dan kelembaban udara dengan alat hygrometer digital, pH dan kelembaban tanah denganmenggunakan soil tester. Hasil penelitian dapat dilaporkan bahwa, Nilai laju penyerapan CO2bervariasi di antara individu satu dengan individu lainnya, demikian pula di antara jenis tumbuhanyang diukur, yakni terendah 4,49 µmol/m2/s dan tertinggi 34,11 µmol/m2/s.

Abstract

Guna mengetahui struktur dan komposisi vegetasi hutan di Taman NasionalLore Lindu Sulawesi Tengah telah di laksanakan pada bulan Mei 2002. Studi dilakukan di 2 lokasi yakni desa Salua (0,5 ha pada 550-640 m dpl.),kabupaten Donggala, and desa Kaduwaa (0,5 ha pada 1100-1150 m dpl),kabupaten Poso. Penelitian dengan “Quadrate-methode” ini mengungkapkan bahwa vegetasi hutan di Salua memiliki jumlah pohon, spesies, jenis dan famili lebih besar daripada di Kaduwaa; namun demikian kepadatan di Salua lebih rendah daripada di Kaduwaa. Vegetasi tersebut di Salua didominasi oleh Palaquium obtusifolium, Toona sureni, Pterospermum celebicum, dan Canarium hirsutum; sedangkan di Kaduwaa oleh Santiria laevigata, Ficus sp., Cryptocarya tomentosa, Semecarpus longifolia, dan Syzygium operculata. Selanjutnya penelitian ini mengungkapkan bahwa komposisi vegetasi pohon di Salua dan Kaduwaa adalah berbeda, tetapi memiliki struktur yang relative sama. Dan akhirnya diungkapkan bahwa komunitas tumbuhan di dua lokasi penelitian adalah berbeda (Indeks kesamaan Sorensen 19).

Abstract

Ecological studies on the Nepenthes species at Barito Ulu, Central Kalimantan, Indonesia were conducted between August 2005 and September 2006. Surveys and two small plot inventories were used to determine the diversity and population of Nepenthes at the study site. We found eight Nepenthes species around the BaritoUlu study area: N. albomarginata, N. ampullaria, N. gracilis, N. hirsuta, N. rafflesiana, N. reinwardtiana, N. stenophylla, and N. hispida. Plot A was dominated by N. rafflesiana with one other species found; whilst in plot B we found five species but it was also dominated by N. rafflesiana. In plot A, the one year stem length growth rate of N. albomarginata was faster than N. rafflesiana (5.0 and 3.5 cm respectively). While in plot B, N. gracilis (21.7 cm) and N. reinwardtiana (13.1 cm) showed faster growth rates than N. albomarginata (5.2 cm), N. rafflesiana (7.0 cm) and N. stenophylla (8.5 cm). Generally, the habitat of Nepenthes in the study site is heath forest.

Abstract

Bawean Island is a remote and tiny island, located approximately 150 km north of Surabaya. In this island it is known to habituate an endemic deer called Bawean deer (Axis kuhlii Mull. Et. Schleg). The animal is protected both nationally and internationally. Understanding the forest as the habitat for this deer is an important step toward the management and the development of the whole habitat. This study was conducted on September 2001 in three locations, known to be the habitat for Bawean deer, that was the Kumalasa, Patarselamat and Pudakit Barat villages. The forest type at study sites was lowland secondary forest. There were 114 species from 90 genus and 56 families. Number of species and trees density at Audacity Barat villages are bigger than Patarselamat or Kumalasa villages. In all study sites, Syzygium lepidocarpa, Irvingia malayana, Garcinia dioica, and Microcos tomentosa are common species.Trees height in three location were under 25 m tall, and stem diameter class were highest among 10-20 cm. Species richness (Ss) ranged from 22,7 to 55,7%. The plant communities in Patarselamat and Pudakit Barat were relatively same, but different with Kumalasa village.

Abstract

The degradation rate of forest in the recent 5 years increases rapidly,particulartly in Sulawesi. The biggest damaged comes from the human impact,which spreads to the conservation area. As a result, the areais decreased,whereas its function and its potency have not been explored. The ecologicalresearch has been conducted in Soloi forest, Suaka Margasatwa Buton Utara inMay 2003. The objectives of this work are to study the condition, which belongto. 75 general and 35 families with density of trees are 277 individual (stemdiameter > 10 cm ), and 1140 sampling ( 2-9,9 cm stem diameter ). The foresttype is low land primary forest, which dominated by Casearia rugulosa,Diospyros pilosanthere, Cleistanthus myriantus, Canarium hirsutum, andDrypetes longifolia. In the forest structure, trees with 10-20 cm stem diameter isin the first rankwith the total number 57,02%, then followed by the trees with 20-30 cm diameter (20,22%). In general, the forest condition in research site isgood, although a few areas are damaged due to illegal loging.
