Abstract

Woods are easy to ignite by fire. Increasing fire resistance with fire retardants is needed to increase safety and reduce losses due to fire. This research aimed to determine the fire resistance of Sengon wood treated with preservation of borax with a concentration of 5%, 10%, and 15% by cold immersion for five days. The fire resistance test used the ASTM E69-02 standard, while the statistical analysis (ANOVA) of the test data used a Completely Randomized Design at the 95% confidence level and the LSD test (Least Significant Difference test). The results showed of the physical properties of Sengon wood, the average value of air-dry moisture content was 14.08%, air-dry density was 0.33g/cm3, and oven-dry density was 0.30g/cm3.  In contrast, the LSD test showed a significant difference between the controls to the all-borax preservation treatments, but between 5%, 10%, and 15% borax treatments were not significantly different. The best fire resistance parameter values ​​were found in the 15% borax treatment, with the retention of 38.04 kg/m3, burning intensity 12.58%, combustion time 437.5 seconds, and effectiveness of 4.76. The fire resistance effectiveness value of all equipment cannot meet the ASTM E69-02 standard

Abstract

The composition of the adhesive content of Tannin Resorcinol Formaldehyde (TRF) is considered more environmentally friendly to use when compared to the phenol resorcinol formaldehyde (RPF) adhesive. In this study to test the strength of the adhesive, acacia (Acacia mangium) and pulai (Alstonia scholaris) were used. This study aims to determine: 1. The characteristics and quality of the adhesive composition of eucalyptus bark tannins, resorcinol and formaldehyde based on SNI 6/4567/1998; and 2. The strength of the gluing composition of eucalyptus bark tannins, resorcinol and formaldehyde on acacia and pulai wood syrup based on SNI 6/6049/1999. The research was conducted using a non-factorial Completely Randomized Design (CRD) consisting of 6 treatments of adhesive composition with 5 repetitions, in order to obtain 30 test samples. The data obtained from the research results were analyzed by means of variance using SPSS 20. Furthermore, if the variance results have a significant effect, further analysis will be carried out using Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results of the research that has been carried out, the six different adhesive compositions produce different values ​​in each treatment, except for treatment P1. P1 has the shape and appearance of a jelly-shaped adhesive so that it cannot be tested and applied to acacia and pulai wood glue. Treatments P2 to P6 can be applied and used for testing and bonding. The pH test and gelatinization test of all treatments were included in SNI 6/4567/1998, the P2 viscosity test did not pass SNI 6/4567/1998. The shear bond strength test was carried out to determine the strength of the adhesive referring to SNI 6/6049/1999, the average value of the best wet shear adhesion test in treatment P6 was 7.89 N/mm2 and the highest average value of shear bonding strength dry on P5 treatment of 26,09 N/mm2.

Abstract

Sugar palm is one of the leading committees widely used by the community as their source of income. The community uses and strives for this palm only relies on palm trees that grow naturally on their land in the forest. One of the constraints on the utilization of palm is the lack of information about the number of initial reserves to the final reserves of the utilization of natural resources. This Research was located in Lombo Village, Pitu Riase Subdistrict, Sidrap Regency, South Sulawesi Province. This study aims to calculate the final supply of raw materials of palm juice and palm sugar based on the number of palm trees owned by farmers. The collected data was done through observation and interviews with farmers involved in the palm sugar business as many as 32 people using census data collection. Data analysis is conducted by calculating initial inventory, addition, depletion (usage), and final supply of palm juice and palm sugar. The results showed that the final reserve amounts of raw materials sap as much as 6,183,799.3 liters. This condition indicates that the final reserves of palm sugar are sufficiently available for this region, with the use of palm juice amounting to 17.2% of the total initial inventory. The addition of stock palm trees can be done by replanting saplings to ensure the continuity of the palm sugar business.

Abstract

The vegetation has many roles, including the ability to reduce pollutants. Ketapang (Terminalia catappa L.) is a species of tree that is often recommended as a shade plant, because it has many advantages including as a pollutant reducing agent.The purposes of this study were to analyse the content of pollutants (lead (Pb), iron (Fe), and manganese (Mn)), and the dust content of ketapang leaves  and compare that pollutant and dust contents based on three area categories (highway, residential area, and vegetated area) in Samarinda City, East Kalimantan Province. The calculation of the number of vehicles that pass around the study site was carried out using the Traffic Survey application. Dimensional measurements of sample trees included diameter at breast height (DBH), tree height, and percentage of tree canopy. The analysis of pollutant contents was done by using AAS (Atomic Absorption Spectrophotometer) with a wet digestion process. The dust content was calculated using the formula where for the calculation of leaf area using millimeter blocks. The result showed that the highest Pb content (100.00 mg/kg), Fe content (347.00 mg/kg), and Mn content (564.00 mg/kg) were in ketapang leaves in Jalan M. Yamin, Jalan Pahlawan, and Jalan M. Yamin, respectively. The highest and lowest dust content were in ketapang leaves in Jalan Pahlawan (0.00316 g/cm2) and Perumahan Bumi Sempaja (0,00024 g/cm2). Based on the area categories, the highest Pb, Fe, Mn, and dust contents were in ketapang leaves that grow on the highway compared to residential and vegetated area. It can be caused by the large number of vehicles passing and canopy density. Information on the pollutant and dust contents in tree leaves can be taken into consideration in selecting plants in different areas.

Abstract

East Kalimantan is one of the areas that have the potential for various traditional medicinal plants. Melastoma malabathricum (known locally as karamunting, senduduk) is an invasive plant in the family of Melastomataceae with a potential medicinal plant. This study explored the potential of twigs and stem bark of Karamunting (Melastoma malabathricum) for its antioxidant and antibacterial activity. The twigs and stem bark of Karamunting were macerated to yield ethanolic extract. The phytochemical screening was evaluated by Harborne and Kokate methods. Antioxidant activity was evaluated by DPPH radical scavenging assay. Antibacterial activity was examined using agar well diffusion method against Propionibacterium acnes. The results showed that the ethanol extracts of twigs and stem bark samples display an ability to inhibit DPPH free radical by 82% and 88% at 50 ppm concentration. Antibacterial activity of the twigs and stem bark samples showed potent activity to inhibit the P. acnes growth with 11.3 mm and 11 mm inhibition activity. Based on the results, the twigs and stem bark of M. malabathricum plants display potential as a natural antioxidant and antibacterial agent.

Abstract

This study aimed to analyze the effectiveness of the smoking method using teak (Tectona grandis) wood waste in the agathis (Agathis sp) wood preservation process. The smoking process was done by putting teak wood waste into the combustion chamber and inserting agathis wood into the smoke room. The smoking duration was divided into 6 hours, 9 hours, and 12 hours with a maximum temperature ±70°C. The analysis carried out was an analysis of the chemical compound using GC-MS pyrolysis and testing the termite based on SNI 7207-2014. The results of GC-MS showed that the resin wood treated with smoking contained anti-termite compounds, namely phenolic, phenyl, and acid compounds, with the highest composition of 92.76% obtained from the duration of 12 hours of smoking. The termite test results showed that untreated wood had a higher weight loss and lower termite mortality than smoked wood. Meanwhile, the longer the smoking process, the lower the wood weight loss with the same mortality rate of 100%. It can be concluded that the smoking method using teak wood effectively increases the durability value of agathis against termites Coptotermes curvignathus.

Abstract

Rubber (Hevea brasiliensis) is a tree species developed in community forests because it has dual benefits in the form of wood and sap. Therefore, the condition of damage to rubber trees needs to be known as a support effort to produce high sap production and the health of smallholder rubber plants. This study aimed to determine the index value of rubber tree damage in the community forest of Ujung Gunung Village, Menggala District, Tulang Bawang Regency. Data collection is done by calculating the tree damage index value through the damage location parameters (X), type of damage (Y), and the severity of tree damage (Z) using a circular plot with a radius of 17.95 cm following the annular plot in the FHM cluster plot design. The results showed that from 111 samples of observations, the index value of tree damage was in the range of 1.2 – 5.5. The damage index includes damage to the rootstock, upper and lower stems, branches, and leaves with cancer damage type, damaged leaves, and dead branches. The location of the dominant damage occurred in leaves with the type of leaf damage, shoots, or shoots damaged with damage index values ranging from 1.2 - 1.9. However, the most significant damage index value occurred in tree damage with the location of the damage on the trunk, type of cancer damage with a severity level of 57%. Thus, the location of the trunk with the type of cancer damage significantly affects the tree's damage with the highest damage index value of 5.5, which can stop the tree from producing latex until death. Control measures can be taken by cleaning the remaining latex and applying fungicides to the stems. In addition, tapping that is organized and does not exploit can prevent damage to the stems.
