Forest is an ecosystem based on the complexity of its components. One of the components of a forest is soil. The importance of soil for human survival and growth for trees. In this ,research we analyzed the physical and chemical characteristics of soil in Sentajo Protected Forest. Soil samples were taken using composite and ring samples techniques. Soil samples were taken from five plot points measuring 20 m x 20 m in two depth level namely, 0-20 cm and 20-40 cm. mixed evenly to get one composite soil mixture. The results of research in Sentajo Protected Forest showed that the land in Sentajo Protected Forest was classified as acidic with a value of 3.68 - 4.34 with organic C content that is classified as low to high and a low KTK value. Moreover, the physical characteristics of the soil in Sentajo Protected Forest were more sandy texture. The values of moisture content, bulk density and porosity at a depth of 0 - 20 cm were higher when compared to a depth of 20 - 40 cm.

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.

The Indonesian government is committed to reducing carbon and greenhouse gas emissions through the Forestry and Other Land Uses (FOLU) Net-Sink 2030 scheme. Efforts that can be made to support the FOLU Net-Sink 2030 is by knowing the carbon storage potential in a forest area. This research aims to calculate the amount of potential biomass carbon storage in the talang forest. The methods used in this research are non-destructive sampling and destructive sampling. The method with destructive sampling for seedlings, understorey and litters, while for saplings, poles, trees and necromass with non-destructive sampling method. The calculation results showed that carbon stocks were trees (77.76 tons/ha), poles (9.56 tons/ha), saplings (7.99 tons/ha), seedlings and understorey (0.65 tons/ha), litters (1.20 tons/ha) and necromass (2.39 tons/ha). Aboveground carbon storage in the talang forest was found to be 99.56 tons/ha. The total aboveground carbon storage potential of the gutter forest was 7,933 tons of carbon. Key words:carbon, biomass, talang forest, FOLU Net-Sink 2030

Palm sap is a liquid produced from palm flower threads. Dates juice can be made into drinks, and sugar, liquid sugar, and block sugar. Many coffee shop companies use sap products and the business feasibility of selling sap products is unknown. This study aims to analyze the feasibility of the juice product business in Binawidya District, Pekanbaru City. Data collection uses observation methods, in-depth interviews, and library research. Sampling by census method. Data analysis was performed with quantitative descriptive analysis. The results of the study show that the total turnover of day shops and coffee shops exceeds the total costs of business actors. The total revenue that is greater than the total cost indicates that the palm juice product business is profitable. The largest total income earned is the coffee shop business with a nominal value of Rp. 46,115,003/mount. The level of income at the coffee shop is influenced by the service of processed palm juice products. The results of the R/C analysis of palm sap product companies in Binawidya District, Pekanbaru City, obtained for each sap product company is R/C ratio > 1, which means the company is profitable and the company is feasible to work on.

Plutella xylostella are one of the pests that attack BPDASHL (Watershed Management Agency and Protected Forest) nurseries in Pekanbaru. One of the plant seedlings attacked by this pest is the Phitecellobium jiringa. Pest control efforts that have a positive impact are botanical pesticides. This study aims to determine the best concentration of a mixture of Citrus aurantifolia leaf extract and Piper betle leaf against hanging Plutella xylostella pests on Phitecellobium jiringa plants. This study used a completely randomized design (CRD), with the treatments namely: P1 = a mixture of C. aurantifolia leaf extract and P. betle leaf 50 g/L, P2 = a mixture of C. aurantifolia leaf extract and P. betle leaf 100 g/L, P3 = a mixture of C. aurantifolialeaf extract and P. betle leaf 150 g/L, and P4 = a mixture of C. aurantifolia leaf extract and P. betle leaf 200 g/L. The observation variables in this study were temperature and humidity, the initial time of death, lethal time50 (LT50), daily mortality, and total mortality. The results showed that the application of botanical pesticide extract of C. aurantifolia leaf and P. betle leaf was efficient on the mortality of hanging P. xylostella pests with a total mortality result of 100%. The best the best concentration is a mixture of C. aurantifolia leaf extract and P. betle leaf 200 g/L (P4).

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.
