Abstract

Tujuan penelitian ini ialah untuk menelaah peranan burung sebagai agen penyebaran benalu yang menginfeksi tegakan jati di Kebun Benih Klonal (KBK) Padangan. Rancangan penelitian berupa Petak Contoh Pengamatan (PCP) terdiri atas Petak Ukur Pengamatan (PUP-PUP) berukuran 50m x 50m sebanyak empat PUP dalam unit PCP dibedakan pada tingkat serangan benalu ringan, sedang, berat dan kontrol. Metode penilaian peranan burung menggunakan focal animal sampling dengan cara pengamatan perilaku burung yang berinteraksi dengan jenis benalu dominan Dendrophthoe pentandra pada jati; dilengkapi inventarisasi jumlah, kelimpahan relatif, dan penyebarannya menggunakan metode IPA (Index ponctualle de’Abondance). Hasil pengamatan menunjukkan terdapat tiga kelompok peranan burung sebagai agen penyebaran benalu ialah: 1) specialist frugivor ialah pemakan buah yang menangani buah benalu secara lengkap dengan cara defekasi, regurgitasi, dan pecking meliputi cabai jawa (Dicaeum trochileum), cabai polos (Dicaeum concolor), cabai gunung (Dicaeum sanguinolentum), dan khusus cucak kutilang (Pynonotus aurigaster) yang menangani buah benalu secara regurgitasi dan pecking dianggap sebagai secondary dispersers, 2) generalist frugivor yang menangani buah benalu secara tidak lengkap dianggap penyebar tambahan (occasionally dispersers) meliputi madu sriganti (Nectarinia jugularis), cinenen pisang (Orthotomus sutorius), madu jawa (Aethopyga mystacalis), 3) opportunistic frugivor yang tidak menangani buah benalu atau berkaitan tidak langsung dengan penyebaran biji benalu sebanyak 13 jenis burung lainnya. Parameter populasi burung menurut jumlah, kelimpahan relatif dan penyebarannya yang luas mencakup lima urutan teratas ialah cabai jawa (D. trochileum), madu sriganti (N. jugularis), bondol jawa (Lonchura leucogastroides), sepah hutan (Pericrocotus flammeus), cucak kutilang (Pynonotus aurigaster).

Abstract

Arbuscular Mycorrhizal Fungi (AMF) is a type of fungus that can form a symbiotic mutualism with most plants. Some AMF can only be symbiotic with a certain plant species. This research aims to determine and obtain the genus AMF from black cumin (Nigella sativa L.) accessions from America, Turkey, Hong Kong, Slovenia, India, and Kuwait accessions which had been grown in West Java, Indonesia. Three samples from each accession, four replications each, were collected for examination. The results showed that six generas of AMF were found in the rhizosphere of black cumin: Glomus, Gigaspora, Acaulospora, Scutellospora, Dentiscutata, and Entrophospora. The genus Glomus was predominantly found in the Indian accession, i.e. 96.42 spores.Keywords: black cumin, diversity, fungi, exploration, AMF

Abstract

Evaluation of land rehabilitation (revegetation) activities is necessary for measuring the extent of success of the ongoing activities in rehabilitating and recovering degraded lands. One way for evaluating the success of land rehabilitation (revegetation) is by determining the changes of micro enviroment. The objective of this research was to study the changes of micro environment in various types of revegetated land cover, including scrub/bush land (SB), agricultural land (TP), monoculture teak (JM) and mixed crops (TC) in Ciliwung upper watershed. Research results showed that the highest air temperature and soil temperature were obtained at SB, respectively at 32.8 °C and 26.5 °C, and the lowest at TC, respectively at 28.1 °C and 20.7 °C. Relative humidity and soil moisture were highest at TC (72.3% and 96%) and lowest at SB (60.8%), and the lowest soil moisture occurred at JM (45%). The highest infiltration rate occurred on TP (475.5 mm h-1, very rapid), followed by JM (117 mm h-1, fast) and TC (80 mm h-1), and the lowest at SB (17.65 mm h-1, medium slow). Erosion reductions occurred after 6 years of the revegetation activities with the following results:TC (96,676.1 ton year-1 ha-1), JM (10,790 ton year-1 ha-1), TP and SB (52,867.9 ton year-1 ha-1 and 24,612.6 ton year-1 ha-1). The micro environments for all land cover types were better after revegetation activities.

Abstract

This study aimed to find out the lead tolerance of sengon (Paraserianthes falcataria) seedling based on growth performance, tolerance index, and ecretion and accumulation of organic acids content. Seedlings were exposed to lead (Pb) with the concentration of 0, 0.5, 1, 1.5, 5, and 10 mM in liquid nutrient culture for 4 days in order to investigate secretion and accumulation of oxalic, malic, and citric content, and for 15 days to examine growth performance and olerance index. The result showed that tolerance index and growth performance of engon seedling were insignificant (p > 0.05) to the rising of Pb concentration up to 1.5 mM with tolerance index at least 95%, and even caused an increase of fresh weight. However, the tolerance index and growth of sengon decreased significantly due to Pb exposure of 5 and 10 mM. Among the three organic acids, citrate was most dominant as compared to malate and oxalate. Secretion of citrate increased significantly (p < 0.05) with the rising concentration of Pb 0.5, 1 and 1.5 mM, reaching to 0.464, 0.540, and 0.587 µg mℓ-1, respectively, or rising according linear line (r = 0.9, p < 0.5). Citrate accumulation showed inconsistent pattern with the rising Pb exposure. The result suggested that sengon seedling have a slightly tolerance to lead by secretion of organic acid especially citric acid.

Abstract

Forest exploitation and conversion to other landuse may cause lost of biodiversity, including most important dipterocarp trees species, i.e. Shorea leprosula and Shorea laevis. The objective of this study was to determine the rarity status of the two important shorea species, i.e. S. laevis and S. leprosula, based on IUCN criteria, their habitat characteristics, and their association with other species, as one of the basis for determining their conservation strategy as a part of forest management. This study was conducted in three types of ecosystem (virgin forest, secondary forest, and fragmented forest) in Muara Teweh, Central Kalimantan. Methodology used in this research includes vegetation and tree diversity analysis. Study results showed that both S. laevis and S. leprosula were included within category of “low risk” in the 3 types of ecosystem in the forest area being studied. Habitat characteristics which determined the absence of S. laevis in the virgin forest habitat was the soil permeability which was too low, whereas other soil chemical and physical properties in the three types of ecosystems were relatively similar. Presence of S. laevis were positively associated with species of S. uliginosa, Dialium platysepalum, Dipterocarpus ibmalatus, Palaquium rostatum, Vatica rasak, Adinandra sp., and Memecyclon steenis. On the other hand, S. leprosula were positively correlated with S. kunstleri, Castanopsis sp., Shorea sp., Quercus bennettii, Castanopsis argentea, and D. hasseltii.
