Abstract

HTI is an industrial plantation forest built in order to increase the potential and quality of production forests by implementing intensive silviculture to meet the needs of industrial raw materials such as wood processing, pulp, and paper. In South Sumatra there is HTI PT. Musi Hutan Persada (MHP) which is one of the largest industrial plantation forest companies in Indonesia. Initially, PT, MHP only planted and produced Acacia Crassicarpa, Acacia Auriculifomis, Acacia Mangium, but now it has been combined with Eucalyptus pellita which is one of the priority types developed in HTI management to obtain its wood fiber. This study was conducted to determine the Eucalyptus pellita plants attacked by pests, the percentage of pest attacks and the level of damage caused by pests. The research method used is a quantitative method, by making transects and observations of Eucalyptus pellita attacked by pests. There are three types of pest attacks found, namely the Zeuzera coffea pest attack on Eucalyptus pellita plants with symptoms of fractures at the base of the stem, swelling and hollow stems. Homona coffearia pest attacks with symptoms of perforated leaves and cut leaf edges or bite marks from pests. Symptoms of Helopeltis sp attacks with symptoms of punctures on the leaves that can cause the leaves to dry and die or if they are still growing the surface of the leaf skin cracks and shrivels. The percentage of Zeuzera coffea pest attacks occurs more in old plants at the age of 6 months only ± 0.002%, the age of 16 months increases ± 0.0277% and at the age of 26 months it is even higher to 0.0580%. While for Homona coffearia and Helopeltis sp pests, they attack young plants more, the older the plant the percentage of pest attacks decreases. During the two-month observation, the percentage of Homona coffearia attacks decreased from 0.0048% to 0.0030%. Likewise with the percentage of Helopeltis sp attacks 0.0090% to 0.0089%. The level of damage to plants due to Zeuzera coffea pests increases with increasing age in plants aged 6 months (0.0004%), 16 months (0.0071%), 26 months (0.0076%). While the level of damage due to Homona coffearia and Helopeltis sp decreases with increasing age of the plant, damage from leaf rollers from 0.0012% to 0.0007%. The level of shoot damage from 0.0023% to 0.0022%.

Abstract

This study was conducted to compare the effectiveness of two planting locations (pond and riverside zone) and two seedling sources (propagule and naturally sourced seedlings) on the growth of the mangrove species Bruguiera sexangula, which is not endemic to the study site. The research employed a quantitative experimental method. The results of this study show that the source of propagule-derived seedlings has a very significant effect on plant growth. Statistically, propagule-derived seedlings produced significantly better growth in all parameters (height, diameter, number of leaves, and root length) compared to naturally sourced seedlings. Meanwhile, the factors of planting location (pond and riverside zone) and treatment combination did not show statistically significant differences. Although descriptively the riverside zone location gave better results in some parameters, the differences were not strong enough to prove that certain locations or treatment combinations were superior to others. The conclusion of this study confirms that in mangrove rehabilitation efforts in non-endemic areas, the selection of seedling propagule sources is an important factor in achieving successful growth.

Abstract

This study aims to analyze the growth of Rhizophora apiculata in the silvofishery system in Simpang Tiga Jaya Village, Tulung Selapan District, Ogan Komering Ilir Regency, South Sumatra Province. The research was conducted to compare the effects of two planting locations—pond and riparian areas—and two types of seed sources, namely propagules and natural wildings, on the growth and survival rate of Rhizophora apiculata. A quantitative experimental method was used, with observations conducted over 4 month on variables such as plant height, stem diameter, number of leaves, root length, and root weight. The results showed that seedlings originating from propagules exhibited higher growth rates and survival percentages compared to wilding seedlings. The highest survival rate was observed in treatment M2S2 (riparian location + propagules) at 76.67%, followed by M1S2 (pond location + propagules) at 72.22%. Soil analysis revealed that the pond location had higher nutrient content, thus supporting more optimal plant growth. Overall, the source of seedlings was identified as the main factor contributing to the successful rehabilitation of Rhizophora apiculata within the silvofishery system.

Abstract

This study aims to examine and analyze the effects of pond planting sites and riparian area planting sites on the growth and development of Bruguiera gymnorrhiza seedlings, as well as to evaluate the survival and growth performance of seedlings originating from propagules compared to those naturally collected from the wild. A quantitative experimental method was employed in this research. The research data were analyzed using ANOVA. The findings indicate that the growth performance of Bruguiera gymnorrhiza seedlings in pond planting sites was superior to that in riparian planting sites with respect to plant height, stem diameter, number of leaves, and root length. Furthermore, seedlings derived from propagules demonstrated better growth outcomes compared to those collected from the wild, particularly in terms of plant height, stem diameter, number of leaves, root development, and survival rate.

Abstract

The Red River Protected Forest is close residential areas, resulting in intensive interactions between communities and protected forest. Directed on the management, extracting forest products not wood and services environment. One management services environments that are going to a business and can be administered in the forest are participating in the scheme incentives services mechanism store and carbon spare. When management will follow the incentives stock and absorb carbon REDD+, so then calculation carbon stock early to important and necessary. This study aims to calculate the amount of savings mobilized carbon the upper surface of the in a protected forest the red river KPHP Meranti. The value of the amount of savings mobilized carbon the above ground of them in the long term, can be used as a baseline to participate in the program REDD+. The data stands in the form of a stake through the stake, with a pole and trees in every type veils and the diameters of tree height measurement (DBH) taken from secondary data the results of previous studies that will be used as a means of calculation stands biomass. The result of this research is saving through the largest carbon in the field were in the protected land cover of secondary 259.3474 Ton/C, second largest carbon savings are covered land shrub with the saving of carbon stock 21.8023 T/c and the smallest carbon stock is in plantations by land cover the carbon stock of 6.2881 Ton/C.

Abstract

Bukit Siguntang Forest, an urban forest on a hill filled by trees that are believed to be a tomb complex of Malay kings. As an ecosystem, Bukit Siguntang Forest also consists of various understorey. Because of the tourist location, the understorey of Bukit Siguntang Forest tends to be easier to encounter cleaning which is considered as weed and disturbs beauty. The study purpose was to explore the aesthetic potential of the understorey vegetation of Bukit Siguntang Forest. The study method used vegetation analysis with the plot measuring 2m x 2m, which was followed by species identification. The results showed that the understorey identified as dominating species with aesthetic potential were Asystasia gangetica, Bidens pilosa, Borreria laevis, Drymaria cordata, and Mimosa pudica. The understorey which is included in herbs and shrubs had beautiful flowers, unique leaf shapes, and attractive colors. These plants provide the beauty of their parts so that they can be applied to form a flower bed, green coverage and refreshing scenery. However, the growth of understorey also needs to be controlled. That is because understorey can grow rapidly, so that will be growing too densely and messy planting mode.Keywords: aesthetic function, Bukit Siguntang, tourism, understorey vegetation.
