Abstract

Extreme climate change affects human life. One of the causes of climate change is the increase of CO2 gas in the air. Forests can absorb CO2 from the air and store it in the form of tree biomass through the process of photosynthesis. One of the forests that can absorb and store carbon is Pertamina Hulu Rokan (PHR) forest, therefore it is necessary to conduct research on estimating the carbon content of PHR Forest area. The methods to be used in this research are non-destructive sampling and destructive sampling methods. The method with harvesting is only for seedlings, undergrowth and litter, while for saplings, poles, trees and necromass with the method without harvesting. Aboveground carbon storage in PHR forest was found to be 95.37 tonnes/ha. The largest carbon stocks were from trees (68.96 tonnes/ha), poles (13.06 tonnes/ha), necromas (5.70 tonnes/ha), litter (3.72 tonnes/ha), saplings (3.54 tonnes/ha) and the smallest carbon stocks were seedlings and understorey (0.39 tonnes/ha).

Abstract

The potential of Non-Timber Forest Products (NTFPs), in general has not been optimally utilized. The processing of NTFPs for the people of Koto Sentajo Village is still not the primary source of income for the community but is part of fulfilling daily living needs. This study aims to determine the types of NTFP utilization and their contribution to the economy of the community in Koto Sentajo Village. This study uses a qualitative descriptive approach, and primary data were collected through observation and in-depth interviews using purposive sampling techniques. Data were analyzed quantitatively. The results of this study found that the types of NTFPs utilized by the people of Koto Sentajo Village are fruits and medicinal plants; the types of fruits are keranji (Dialium indum), tampui (Baccaurea macrocarpa), geruntang (Phoebe grandis), cempedak (Artocarpus fretessii), forest durian (Durio zibethinus), kulim (Scrodocarpus borneensis), petai (Parkia speciosa), and barangan (Castanopsis argentea). In contrast, the types of medicinal plants most widely utilized are sepico (Eurycoma longifolia Jack) and rosam (Dicranopteris linearis). The contribution of NTFPs to the people's economy in Koto Sentajo Village is 5.6% of the total income of the community, or around IDR 1,519,851/person/year, to the average total income of IDR 26,983,265/person/year

Abstract

The decline in productivity of Acacia seedlings (Acacia crassicarpa) in Industrial Plantation Forests is caused in part by attacks of mealybug pests (Paracoccus marginatus). Using chemical insecticides in pest control can negatively impact health and the environment, so more environmentally friendly alternatives are needed, such as plant-based insecticides. This study aims to determine the concentration of noni leaf extract on the mortality of mealybug pests. A completely randomized design (CRD) was employed, consisting of four treatments with different concentrations of Morinda citrifolia leaf extract (30 g/l, 40 g/l, 50 g/l, and 60 g/l), each replicated three times. The observed parameters included the time of initial death, Lethal Time 50 (LT₅₀), and total mortality percentage. The results indicated that the use of Morinda citrifolia leaf extract of 60 g/l was the most effective, with an average time of 8,67 hours, LT₅₀ of 24,67 hours, and total mortality rate of 100% for Paracoccus marginatus.

Abstract

The use of Scorodocarpus borneensis Becc as wood causes its availability in nature to decrease. An alternative step to utilize and maintain the availability of Kulim in nature is to utilize Scorodocarpus borneensis Becc’s bark extract. The bioactive substances and scent of Scorodocarpus borneensis Becc are considered capable of repelling insects and replacing DEET in chemical mosquito repellent raw materials. The use of Kulim wood extract is considered to be far better than the use of chemicals that can affect human health. This research was conducted in three laboratories, namely the forestry laboratory, organic chemistry laboratory and natural synthesis and chemical engineering laboratory. The parameters to know the quality of the extract from the bark of the Scorodocarpus borneensis Becc’s branch were yield observation, color observation, odor test and skin sensitivity, phytochemical test and the extract effectiveness test against mosquitoes which were expected to be in accordance with the criteria of the pesticide commission of the Department of Agriculture in 1995. The results showed that the yield from Scorodocarpus borneensis Becc’s wood extract was found to be worth 0.83%, the color of the extract was brown because it used water solvent, the distinctive aroma of the Scorodocarpus borneensis Becc was not found in the extract because it was dominated by tannins and the extract felt warm on the skin, phytochemical tests showed that the kulim extract contained substances such as saponins, phenolic, steroids and tannins as well as the effectiveness test of the extract against mosquitoes found a protection result of 44% which has not been able to meet the standard of repellent protection criteria from the Pesticide Commission of the Department of Agriculture in 1995.

Abstract

Wood was a construction raw material that has long been developed before the advent of concrete and steel technology. The need of wood raw materials for construction was increasingly increasing while the availability of high quality wood was increasingly scarce. Therefore, in order to meet this an effort was needed to produce raw materials to replace wood, its was the development of laminated products or glulam made of bamboo apus (Gigantochloa apus) as structural and construction materials. Based on this, this study was conducted to determine the quality of glulam from Gigantochloa apus by using styrofoam adhesives based on number and pattern of layer arrangement. Sample was made of Gigantochloa apus with sized 30cm × 10cm arranged with the number and pattern of layer arrangement that have been determined. This study uses a complete randomized design combination with two treatments. Factor A was the number of layers (three layers, four layers and five layers) and factor B was the arrangement pattern (diagonal, horizontal and vertical). The physical and mechanical properties of glued laminated beams of Gigantochloa apus were tested based on JAS 234: 2003 Standard. The results showed that the quality of glulam met the physical properties of moisture content. While the mechanical properties of MOE and MOR did not meet the standards, so they did not be use as structural materials. Combination with horizontal, diagonal and horizontal lamina arrangement patterns gives the best results on the mechanical properties of glulam.

Abstract

Bamboo is one of the non-timber natural forest products that has the potential to be used as raw material for wood substitutes because bamboo has many advantages. If for wood with high durability, it takes time from planting seedlings to be ready for harvest is 30-40 years and even then after cutting down the seeds must be planted again, but bamboo takes up to 4-5 years to be ready to be harvested. The problem that arises is that bamboo has a limited dimension so that it requires lamination technology that can shape bamboo into a dimensioned material according to construction needs. Lamination technology is an alternative way of processing bamboo that is relevant to achieving the expected goals. Lamination can make the strength of betung bamboo far higher than solid wood blocks. Tests carried out by physical and mechanical tests of betung bamboo lamination using JAS 234: 2003. Testing the physical properties of the betung bamboo includes a wood density test for moisture content testing, and thickness swelling. The mechanical properties of the betung bamboo include the modulus of rupture and modulus of elasticity tests. The lamination test has variations in the number of layers A1 (3 layers), A2 (5 layers), and A3 (7 layers) with 3 replications each. Betung bamboo density obtained an average of 0.316 gr/cm3 to 0.453 gr/cm3, the average moisture content of betung bamboo was 11.386% to 12.444%, and the average thickness swelling test was 0.240% to 0.293%. Modulus of rupture test is 210,160 kg/cm2 to 925,963 kg/cm2, and the modulus of elasticity test shows an average of 0.916 kg/cm2 to 925,963 kg/cm2. The physical properties of the betung bamboo (Dendrocalamus asper) meet the JAS 234: 2003 standard is the moisture content, for the density and thickness swelling bamboo betung lamination is not required in the JAS 234: 2003 standard. The mechanical properties of betung bamboo laminate for MOE values are equivalent to wood strength classes II-IV and MOR are equivalent to wood strength classes V.
