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

One of the pests that attacks Eucalyptus pellita is Paracoccus marginatus. Currently, chemical pesticides are used to control these pests, which can harm health and the environment. As a result, we need a more environmentally friendly alternative biopesticides that comes from a combination of Carica papaya leaf and Tinospora crispa stem extracts. The aim of this research was to determine the effect of Carica papaya leaf and Tinospora crispa stem extracts on Paracoccus marginatus pests in eucalyptus nurseries and to determine the best concentration for controlling Paracoccus marginatus pestsThe experiment used a completely randomized design (CRD) with 4 treatments and 4 replications. The treatments consisted of different concentrations of Carica papaya leaf and Tinospora crispa stem extracts (20, 40, 60, and 80 g/l). This was followed by a DNMRT test at 5% confidence level. The results showed that the combination of Carica papaya leaf and Tinospora crispa stem extracts significantly affected Paracoccus marginatus mortality. The best concentration of the extract mixture was 80 g/l, which resulted in the fastest mortality rate, with an LT50 of 26.41 hours and 100% total mortality.

Abstract

Bukit Cadika Pine Forest Bangkinang is one of the pine forests in Bangkinang Riau. Pine is a type of tree that is classified as a fast-growing type and does not require special requirements in its planting, so pine can spread naturally to areas south of the equator. The existence of understory plants can also function as soil protectors from rain grains and surface flow and play a role in increasing organic matter in the soil. This study aims to determine the diversity of understory plant species in Bukit Cadika Pine Forest stands Bangkinang. Data collection methods and lower plant samples were carried out in pine stands through direct field observations using the path/transect method. The placement of paths in this study was carried out using purposive sampling technique with a total of 5 paths made and a distance of 1 m between paths with a path length of 100 m. The data obtained in the field were analyzed using the data collection method. Data obtained in the field were analyzed using the Shannon-Wiener diversity index, species evenness index and important value index. The conclusion in this study found as many as 13 species with a total of 201 individuals and 12 families that were successfully identified and the species diversity index in Bukit Cadika pine forest stands amounted to 2.18 which is included in the moderate category.

Abstract

Mangrove diversity in Indonesia, including in Sonde Village, Rangsang Pesisir District, and Meranti Islands Regency, is one of the country's assets that is very important both ecologically, socially, and economically. This study aims to determine the diversity of mangrove species in the Tuah Sonde Forest Farmer Group Community Forest area. The method used was transect with random start with vegetation data collection conducted from June to July 2022. Data analysis includes quantitative descriptive analysis by calculating the Important Value Index (IVI) and the Shannon-Wiener Diversity Index (H'). The results showed that there were six mangrove species found in Sonde Village, namely Rhizophora apiculata, Ceriops tangal, Bruguiera cylindrica, Xylocarpus granatum, Sonneratia alba, and Avicennia marina. Sonneratia alba species dominated at the tree level with the highest INP of 167.66%, while Rhizophora apiculata dominated at the seedling and sapling levels with INPs of 111.52% and 76.74% respectively. The species diversity index (H') at the seedling and sapling level shows a medium category, while at the tree level is in the low category. Mangrove species diversity in Sonde Village is influenced by environmental factors such as tides and human activities, especially illegal logging which has the potential to reduce the sustainability of mangrove ecosystems in the region.

Abstract

Swietenia mahagoni can grow on marginal land and is suitable for use as a revegetation plant. Peat is classified as marginal soil due to its high organic acid content and low levels of macronutrients. One approach to improving the productivity of peat soil is the application of ameliorants, one of which is oil palm boiler ash. This study aimed to evaluate the effect of mixing peat with oil palm boiler ash and to determine the optimal composition of this mixture for the growth of mahogany seedlings. A completely randomized design (CRD) was employed, consisting of five treatments with four replications, resulting in a total of 20 experimental units. The planting media compositions tested were: P0 = 100% peat soil (control), P1 = 10% boiler ash + 90% peat soil, P2 = 15% boiler ash + 85% peat soil, P3 = 20% oil palm boiler ash + 80% peat soil, and P4 = 25% oil palm boiler ash + 75% peat soil. Data were analyzed using SPSS version 26.0. The application of oil palm boiler ash had a significant effect on the growth of mahogany seedlings. The optimal composition was 15% boiler ash and 85% peat, which resulted in an average seedling height increase of 10.01 cm and an average dry weight of 6.61 g.
