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

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

Agroforestry is a forestry and agriculture plant utilization system using sustainable land management to gain more products. Falcataria moluccana is a forestry plant that has been cultivated mostly in an agroforestry system by the Indonesian people, particularly on Java Island. Appropriate F. moluccana species selection and planting space in an agroforestry system are expected to improve plant growth and suppress the damage level that occurred in F. moluccana. The agroforestry system with F. moluccana and rice plant (Oryza sativa) is one of the alternative ways to support the national food needs. This study aimed to analyze the growth of various provenances of F. moluccana at the age of 14 months and analyze the productivity of IPB 3S rice in two planting spaces of F. moluccana. This study used a completely randomized two-factorial design, with the first factor being the provenance of F. moluccana, i.e., Solomon F1, Solomon F2, and local Kendal, and the F. moluccana spacing of 1.5 m x 3.0 m and 1.5 m x 1.5 m was the second factor. The F. moluccana growth parameters, rice plant growth parameters, and rice plant productivity in agroforestry systems were analyzed using an analysis of variance (ANOVA). If a significant effect on each parameter at a 5% confidence level occurred, the parameters were further analyzed with Duncan's Multiple Range Test (DMRT). The study found that provenance had no significant effect on the growth of 14-month-old F. moluccana. The results also showed that the growth of 14-month-old Solomon F2 had a relatively higher value on the parameters of height and diameter. The highest productivity of IPB 3S rice was found in the local F. moluccana shade at a spacing of 1.5 m x 1.5 m, reaching 0.201 tons/ha. The highest rice productivity was due to the magnitude of the light intensity received by rice of 5414.30 lux.

Abstract

Sorghum (Sorghum bicolor L.) and nypa fruit skin fiber (Nypa fruticans Wurmb.) can be used as raw materials in the manufacture of eco-friendly particleboard (PB) using natural adhesives based on citric acid and sucrose. This study aimed to determine the characteristics of PB from sorghum and nypa fruit skin fiber using citric acid-sucrose adhesive and also to determine the optimum composition of raw materials and adhesives in the manufacture of PB. The PB panel was made by mixing raw materials and adhesives with variations in the composition of nypa fruit skin fiber:sorghum raw materials 100:0, 25:75, 50:50, and 0:100, and variations in the concentration of citrate-sucrose adhesive were 20% and 30%. The target dimensions and density of PB were 25 cm x 25 cm x 0.9 cm and 0.8 g/cm3, respectively. The PB was hot-pressed for 10 min at 200oC with a pressure of 11 MPa. The physical and mechanical properties of PB were determined using the Japanese Industrial Standard (JIS) A 5908:2003 standard. The results showed that the PB has average values of moisture content of 11.94%, density of 0.79 g/cm3, water absorption of 52.96%, thickness swelling of 13.21%, modulus of elasticity of 1029.55 N/mm2, modulus of rupture of 6.46 N/mm2, internal bonding of 0.18 N/mm2, and screw holding power of 43.12 N. Variation of raw materials composition has a significant effect moisture content, water absorption, thickness swelling, modulus of elasticity, and modulus of rupture. Applying 30% adhesive content significantly affected water absorption, thickness swelling, and screw holding power. Keywords: citric acid-sucrose, nypa fruit skin, particleboard, sorghum

Abstract

Ficus hispida and Ficus racemosa are Moraceae species that commonly grow on riverbanks. Actions to propagate generative plants required more observation due to mutualistic symbiosis between F. hispida and F. racemosa with Ceratosolen solmsi and Ceratosolen fusciceps as pollinating insects. This study aimed to obtain data on seed production, germination, and the interaction of F. hispida and F. racemosa with pollinating insects. Research activities included seed extraction, seed germination testing, and calculation of the number of pollinating insects found in syconia. The results showed that the number of entered insects was related to syconia's receptive phase and diameter. F. hispida produced 3679 seedlings, while F. racemosa produced 2086 seedlings in one period. The number of seeds could cover a 6 ha area with a 4 m x 4 m spacing of planting. The germination percentage of F. hispida and F. racemosa was low to moderate. F. hispida seed germination was only 57.2% and F. racemosa was 68.6%. Thus, the seed should be germinated immediately after extraction. Keywords: Ficus hispida, Ficus racemosa, germination, seed production

Abstract

Badung is one of the regencies in Bali province, which is formed by varied landforms with different characteristics. The objective of this study was to identify environmental issues that arise in volcanic and fluvio-volcanic ecoregions in terms of abiotic, biotic, and cultural aspects. The method used to determine the sample in this study was purposive sampling. Meanwhile, the methods used in data collection were surveys and interviews, then analyzed using an ecoregion concept approach and based on resources in the research study area. The research study approach uses a descriptive-analytical approach. The results showed several environmental issues in the research area, mainly caused by human activities, such as agriculture, nature tourism, and fishery. However, several issues were insufficiently coped. Among them, there is an incompatibility in the use of water springs and the accumulation of garbage around the springs in Sibangkaja Village. It might be due to the lack of awareness of the surrounding community towards household waste management. In addition, the handling of river pollution from liquid and solid waste in Sangeh Village has not been managed optimally.

Abstract

Post-treatment of bamboo-oriented strand board (BOSB) through thermal modification can be an alternative to improve BOSB quality. This study aimed to analyze the effect of post-thermal treatment duration on the physical and mechanical properties of BOSB. Three-layers BOSB with a target density of 0.7 g/cm3 was made with the core layer perpendicular to the surface and bonded with 8% phenol-formaldehyde resin. The BOSB produced was then thermally-modified at 160°C for 1, 2, and 3 h. The physical and mechanical properties of BOSB were determined based on JIS A 5908-2003 standard. The results showed that the physical properties of the thermally-modified BOSB increased while the mechanical properties decreased compared to the untreated BOSB. The moisture content (MC), water absorption (WA), and thickness swelling (TS) of BOSB decreased with the increase in post-thermal treatment duration. The decrease in MC, WA, and TS of the thermally-modified BOSB reached 38.60%, 11.92%, and 33.26%, respectively. In addition, the decrease in modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding of the thermally-modified BOSB reached 19.18%, 23.15%, and 53.51%, respectively. The results showed that TS, MOE, and MOR of the thermally-modified BOSB still could meet the 0437.0 standards for commercial OSB (Grade O-1). Keywords: bamboo-oriented strand board, Dendrocalamus asper, physical and mechanical properties, post-thermal treatment, treatment duration

Abstract

The planning of wetland essential ecosystem area (EEA) conservation and preservation activities is important to support ecosystem stability, including the mangrove ecosystem. These activities should consider the ecological, economic, and social aspects. This study aimed to analyze the indicator of the mangrove ecosystem to support the planning program of EEA conservation in Muara Kali Ijo, Pantai Ayah, Kebumen. The research method used the mapping and planning analysis of the EEA conservation program using the indicator of mangrove density, mangrove diversity, and environmental indicators. The results showed that mangrove density in Muara Kali Ijo was 1,500-4,300 trees/ha (moderate to very dense) and was dominated by Rhizophora mucronata and Rhizophora styllosa. The potential of total dissolved solids, water salinity, potential hydrogen, dissolved oxygen, biological oxygen demand, and nitrate had a good condition to support the mangrove's life and growth. The ecosystem essential planning also had activity to conserve and preserve the Crocodylus porosus. The planning of ecosystem essential was developed in 18.5 ha, divided into five zones: mangrove preservation area of 5.90 ha, mangrove utilization area of 6.40 ha, mangrove arboretum of 4.40 ha, mangrove rehabilitation area of 1.30 ha, and specific utilization area of 0.5 ha. The wetland EEA in Muara Kali Ijo has important value in preserving the area from coastal disaster and increasing economic value with tourism and other activities.

Abstract

This research aimed to analyze the change in chemical composition of the betung bamboo (Dendrocalamus asper) strands after alkali immersion treatment under various immersion times. The bamboo culms were converted into strands with the target length, width, and thickness of 70, 25, and 0.5 mm, respectively. Strands were alkali immersion-treated with 1% NaOH solution for 1, 2, and 3 h. Preparation of powder for chemical component analysis refers to the Technical Association of the Pulp and Paper Industry (TAPPI) standard T 264 cm-07 regarding the preparation of wood test samples for chemical analysis. Structural and non-structural bamboo strand chemical components such as holocellulose, alpha-cellulose, hemicellulose, klason lignin, and extractives were analyzed. The results showed that alkali immersion treatment decreased the hemicellulose content from 21.55% before treatment to 20.30% after 3 h immersion. Thus, it changed the holocellulose and alpha-cellulose composition. Alkali immersion treatment also changed the extractive substances dissolved in cold water, hot water, 1% NaOH, and ethanol-benzene solution. The decrease in hemicellulose, molecular weight lignin, and extractive substances would be beneficial for bamboo-oriented strand board manufacture to improve strand adhesion, dimensional stability, mechanical properties, and durability against biological agents attack. Keywords: alkali immersion times, alkali immersion treatment, bamboo, chemical components, pre-treatment

Abstract

Forests have a role as carbon sinks and come under the spotlight when the world is facing the climate change problem. Urban forests have functions as the most effective carbon sinks. Banda Aceh City only has 7.15 ha of urban forest, and the vegetation that grows in the urban forest is essential for carbon emissions reduction. This study aimed to determine the potential tree biomass and carbon sink value in the BNI Urban Forest, Banda Aceh City, Indonesia. This study used vegetation analysis by inventory method with the census sampling method. The diameter of all trees was measured, and tree biomass, carbon stocks, and carbon sequestration were calculated. This study identified 16 tree species in the BNI Urban Forest with a total of 318 individuals, showing Casuarina equisetifolia as the most dominant tree (163 trees). The above-ground biomass, carbon stock, and carbon sequestration by the vegetation in the BNI Urban Forest were 24.66 tons/ha, 11.59 tons/ha, and 42.51 tons/ha, respectively. This study presented the vegetation conditions and the potential of carbon sequestration, which can be used to monitor and evaluate the benefits of the existence of urban forests in Banda Aceh. Keywords: carbon sequestration, carbon stock, green open space, tree biomass, urban forest
