Abstract

Endophytic fungi have been reported to promote plant growth and resistance to biotic and abiotic stresses. This study aimed to determine the effect of endophytic fungi application isolated from the sengon (Falcataria moluccana) seeds on the growth of sengon. The seed-borne endophytic fungi were applied when the session was three weeks old by sprinkling each suspension of endophytic fungi (103 to 106 spores/ml) on the soil around the plant roots. The experimental parameters evaluated were height, diameter, and total wet and dry weight. This study showed that endophytic fungi treatment has no significant effect on the stem diameter, total wet weight, and water content; but significantly affected the height and total dry weight. Cladophialophora sp. and Ascotricha sp. fungi increased the height growth of sengon, while Aspergillus sp. fungi increased the total dry weight against the control. Ochroconis sp. treatment was not significantly different from the control. The shoot-root ratio values range from 1.13-1.43, indicating that the seeds already have roots supporting plant growth. The Dickson quality index range from 0.65-1.03 suggested that the seedlings have good biomass distribution. Consequently, endophytic fungi have the potential to increase the growth of sengon seedlings. Keywords: endophytic fungi, Falcataria moluccana, seedling growth, sengon

Abstract

Cajuput (Melaleuca cajuputi) has the potential to be developed with monoculture and agroforestry patterns in ex-coal mining land. This study aimed to analyze the oil yield and cineole content of cajuput planted with monoculture and agroforestry and patterns in ex-coal mining land. The research design used a split-split plot design with three factors: planting pattern, fertilizer dosage, and lemongrass (Cymbopogon nardus) plant spacing. The variables measured included the oil yield and cineole content of cajuput. This study was conducted in cajuput monoculture and agroforestry patterns with lemongrass G2 variety and Sitrona 2 Agribun variety, with various spacing. The study was conducted for six months, with one harvest of cajuput leaves in the sixth month. The results showed that lemongrass's planting pattern and plant spacing significantly affected cajuput oil yield. However, treatment of the dosage of fertilizer had no significant effect on cajuput oil yield. The treatment of lemongrass plant spacing only significantly affected cineole content, but planting patterns and fertilizer dosages had no significant effect. The cajuput agroforestry with the Sitrona 2 Agribun variety produced the highest oil yield (2.84%) and cineole content (50.70%), compared to the monoculture pattern and cajuput agroforestry with G2 variety. The lemongrass plant spacing of 0.5 m x 0.5 m produced the highest oil yield (2.73%) and cineole content (52.98%) compared to 1 m x 1 m plant spacing Cymbopogon nardus. Keywords: agroforestry, cineole, essential oil, ex-coal mining, Melaleuca cajuputi

Abstract

Amorphophallus is a protected and endangered plant. Some Amorphophallus species can only grow in certain environmental conditions. Differences in environmental conditions could cause differences in morphology and distribution of Amorphophallus. This study aimed to obtain the morphological characteristics of Amorphophallus and study the distribution of its population at several altitudes in Mount Poteng, Raya Pasi Nature Reserve, West Kalimantan. The study used an exploratory survey following the river's flow at the Raya Pasi Nature Reserve, especially in Mount Poteng. The results found three species of Amorphophallus: Amorphophallus borneensis (109 individuals), Amorphophallus gigas (9 individuals), and Amorphophallus hewittii (27 individuals), showing clustered distribution patterns with a Morista index of > 1. The similarity index of six comparisons for each altitude showed five altitudes with similar categories and one altitude with a very different category. The results revealed that the Amorphophallus distribution positively correlated with air temperature and soil temperature but negatively correlated with air humidity. However, all correlations were weak. The morphological differences of the three Amorphophallus species were in the forms of the stem pattern, stem height, and fruit shape. The distribution of Amorphophallus can be found at an altitude of 200 − > 500 masl, which is not far from the river flow. Keywords: altitude, Amorphophallus, Mount Poteng, Raya Pasi Nature Reserve

Abstract

Data on the biodiversity is essential to support the Forest Area with the Special Purpose (KHDTK) of Gunung Bromo as an educational forest and training center. This study aimed to obtain basic information on undergrowth vegetation composition under pine stands. Furthermore, the important value index (IVI), species diversity index (H'), species richness index (R), and evenness index (E) were determined. The data was systematically obtained by marking 35 plots of 2 m × 2 m. The distance between plots was 100 m. The results showed that the undergrowth vegetation consisted of 39 species from 26 families. The habitus of undergrowth vegetation was herb (15 species), shrub (14 species), liana (3 species), fern (6 species), and palm (1 species). Eragrostis tenerum was the dominant species with an IVI of 58.84%). Centrosema pubescens showed an IVI of 18.38%, while the other species showed less than 10%. Furthermore, H' was classified as moderate (2.35), R was classified as moderate (4.69), and E was classified as uneven (0.64). This condition indicated that the undergrowth species that grew in KHDTK of Gunung Bromo was limited and uneven. It was considered due to inhibiting factors such as allelopathy in pine leaf litter and low light intensity. Undergrowth species that grow in KHDTK of Gunung Bromo showed several potential utilizations, such as medicinal plants (30 species), ornamental plants (9 species), food sources (5 species), forage (4 species), culture and crafts (4 species), and conservation (3 species). Keywords: important value index, KHDTK of Gunung Bromo, species composition, species diversity, undergrowth vegetation

Abstract

Mangrove forest in North Central Timor Regency is dominated by Rhizophora sp. The highest number was found in Tuamese Village, namely Rhizophora apiculata and Rhizophora mucronata. The biomass productivity in mangrove forests varies according to age, dominant species, and locality. It shows differences in carbon uptake and storage at the level, type, and place of growth. This study aimed to analyze the carbon content and carbon uptake of R. apiculata and R. mucronata at the stake level to the tree level in two plots with the size of 2,000 m2 each. The method used was allometric equations, while the power discrimination test used an independent sample t-test. The result showed that R. apiculata and R. mucronata had the same potential in producing biomass and necromass as well as in storing and absorbing carbon. The total biomass was 77.21 Mg/ha, which can absorb and store carbon, respectively, 141.68 Mg/ha and 36.61 Mg/ha. This research data provides an overview of the potential of biomass in meeting carbon trading standards as an effort to succeed in mangrove conservation in Tuamese Village. Keywords: Biomass, Carbon uptake, Rhizophora apiculata, Rhizophora mucronata

Abstract

The objective of this study was to evaluate the use of bagasse-activated charcoal for reduced formaldehyde emissions and their effect on the physical, mechanical, and biological properties of particleboard. Activated charcoal was made by carbonizing bagasse at 300°C for 2.5 h, followed by carbon activation using a 0.1M HCl solution for 24 h. Particleboards were made of a mixture of bagasse and wood particles with a ratio of 100:0, 75:25, 50:50, 25:75, and 0:100. The concentrations of activated charcoal used in manufacturing particleboards were 2, 4, and 6% based on the dry weight of the particles. Particleboards were made with a target density of 0.7 g/cm3 and hot-pressed at 140°C for 10 min with a pressure of 35 kg/cm2. The observed parameters were formaldehyde emission levels, physical properties, mechanical properties, and biological properties of particleboards. The results showed that the more activated charcoal added in the manufacture of particleboards decreased formaldehyde emissions of the panel. Based on the SNI 5008.2:2016, the overall formaldehyde emission value of particleboard in this study with activated charcoal is in the F* category. The addition of activated charcoal improved the physical, mechanical, and biological properties of particleboards in terms of increased density, decreased water content, water absorption, and thickness swelling, increased modulus of elasticity, modulus of rupture, internal bonding, and screw withdrawal, as well as increased resistance to termites. The particleboard with the addition of 6% activated charcoal showed better mechanical, physical, and biological properties. All physical and mechanical properties of particleboard met the JIS A 5908-2003 Type 8 standards, except for the modulus of elasticity. Keywords: Activated charcoal, bagasse, biological properties, formaldehyde emission, mechanical properties, particleboard, physical properties

Abstract

Tree health monitoring of risky trees is necessary, especially in areas with a high level of accessibility, such as in hotels and tourist areas. The increased accessibility of hotel visitors and the green space require increased awareness of the risk of falling trees. This research aimed to estimate the amount of internal decay and damage of living trees, with special attention to the large tree in the open space of R Hotel Rancamaya. Tree health monitoring was carried out using two approaches, namely visual observation Sonic Tomography method. The visual parameters were observed following the standard method of the International Society of Arboriculture. A total of 8 trees consists of four types of plants such as Melia azedarach, Durio zibethinus, Falcataria falcata, and Ficus subcordata. The eight trees visually showed no significant damage to their organs. The results of internal trunk inspection by PiCUS-3 Sonic Tomograph also showed a similar result with decay or weathering ranges ranging from 1-3% in healthy trees, except for the stem base of tree 7 (M. azedarach) with weathering of 18%. Handling that needs to be done on six trees at the green area hotel is through light pruning and installing warning signs so that visitors and staff are careful in the tree area. Substantial pruning is recommended specifically for tree 7 because there is significant weathering, and it could be dangerous if the tree is not appropriately handled. The assessment showed that mitigation, warning signs, and physical handling are essential to prevent any unpredicted fallen trees, especially for tree 3 (D. zibethinus) and tree 7 (M. azedarach).

Abstract

Canarium (Canarium indicum) seeds have mechanical dormancy, i.e., seeds have a hard outer seed coat, which causes inhibition of germination. Mechanical dormancy can be broken by mechanical and chemical scarification. One way of chemical scarification is water soaking. This study aimed to analyze the initial effect of temperature of the soaking water and duration of soaking on the germination of canarium seeds. The research design used was a two-factor experiment in a completely randomized design. The first factor is the different initial water temperature and the second factor is soaking duration. The initial water temperature consists of 60°C, 70°C, 80°C, 90°C, and 100°C, while the soaking duration consists of 0 h, 24 h, 48 h, and 72 h. The results showed that the initial water temperature had a very significant effect on germination percentage, peak value, mean daily germination, and germination value. The soaking duration did not significantly affect germination percentage, mean daily germination, and germination value, but it significantly affected the peak value. The interaction of initial water temperature and soaking duration significantly affected the germination percentage, mean daily germination, peak value, and germination value. The initial water temperature and soaking duration affected the germination of canarium seeds. Keywords: Canarium indicum, dormancy, germination, initial temperature, soaking duration

Abstract

Solomon sengon is a provenance of sengon that grows faster than other local sengon species. The species is often cultivated in an agroforestry system, which can be combined with rice as the staple food in Indonesia. Competition between those two components to obtain the sunlight and nutrients is getting higher as sengon grows. LIPI and IPB have discovered several rice varieties. However, there has not been much research done on agroforestry between Solomon sengon (Falcataria moluccana) and rice (Oryza sativa) varieties. This study aimed to analyze the growth of Solomon sengon at 14 months old and the productivity of several rice varieties. This study used a completely randomized factorial design with two factors, namely the tree spacing factor of Solomon sengon type F2 (1.5 m × 3 m and 1.5 m × 1.5 m) and the factor of upland rice varieties (LIPI Go 1, LIPI Go 2, and IPB 9G) also lowland rice (IPB 3S). Parameters observed were sengon growth and rice productivity. Data were analyzed statistically using the analysis of variance (ANOVA) test and the Duncan test with a confidence interval of 95%. The results showed that the 14-month-old Solomon sengon with a tree spacing of 1.5 m × 3 m has a higher diameter, height, and canopy area than a tree spacing of 1.5 m × 1.5 m. The rice varieties of LIPI Go 1, LIPI Go 2, IPB 9G, and IPB 3S planted under 14-month-old sengon with a tree spacing of 1.5 m × 3 m have higher productivity than rice planted under sengon with a tree spacing of 1.5 m × 1.5 m. Rice varieties significantly affected several rice growth parameters. IPB 3S has the optimum growth and production in this study. IPB 3S is the variety with the highest number of tillers per clump and the highest number of productive tillers per clump. IPB 3S is the variety with the highest number of tillers per clump and the highest number of productive tillers per clump. Keywords: agroforestry, rice, Solomon sengon, tree spacing
