Abstract

Green line is one way to fulfill the existence of green open space in urban areas, it was covered by various types of plants from land cover crops to trees. The condition of trees in the green lane must be in good condition and healthy so it can comfort the road users. Considering the importance of trees in urban areas, the health of trees must be considered to prevent accidents which caused by trees along the road. The purpose of this research was to evaluate the health of trees on the green lane at Arifin Achmad street, Pekanbaru. This research was conducted by census method and scoring method that consisting of the health and quality of trees along Arifin Achmad street. The quality of trees in the green line at Arifin Achmad in Pekanbaru City were reviewed from stem health (75,59%) it means that the trees on the green lane were healthy. The quality of trees of threats to roads, sidewalks and drainage networks (81,66) classified into light category.

Abstract

Anthocephalus cadamba can be used as one of the alternative plantations because Anthocephalus cadamba is a fast-growing plant species. Disorders by disease attacks can reduce the quality and quantity of wood in the Anthocephalus cadamba stands. Diseases that attack a plant forest population can be very destructive and accompanied by symptoms and signs. Disease attacks will result imbalanced ecosystem if it is not properly considered. The purpose of this research was to determine the intensity of disease attacks on Anthocephalus cadamba stands. Research conducted on Anthocephalus cadamba stands that have an area of 2 ha with a plant distance of 3m x 4m using the survey method showed the intensity of disease attacks on Anthocephalus cadamba stands at Raya PasirPutih street was 24,75%. The most common criteria for the attack of Anthocephalus cadamba disease are mild attacks by 91,0%, then healthy by 5,5%, then moderate attacks by 2,5% and the least were severe attacks by 1,0% of 800 Anthocephalus cadamba stands.The disease that attacks the Anthocephalus cadamba stands were leaf spot, flour dew, soot dew and stem cancer.

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

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

Pests and diseases are recurring issues in the cultivation of forest plant seedlings, as they can reduce seedling quality and lead to economic losses due to seedling mortality. Identifying the types of pests and diseases is crucial for implementing more effective, efficient, and environmentally friendly control measures to maintain seedling quality. The methodology used in this study was a field survey with direct observation of seedlings affected by pests and diseases. Data collected included the types of pests and diseases observed in various seedlings, such as Annona muricata, Albizia saman, Archidendron pauciflorum, Parkia speciosa, Nephelium lappaceum, Pometia pinnata, Persea americana, Durio zibethinus, Garcinia mangostana, and Artocarpus heterophyllus. Observations were conducted over an eight-week period. The damage caused by pests and diseases in the BPDASHL nursery was categorized as relatively mild. Common pests identified included beetles, borers, and mealybugs. Meanwhile, diseases frequently observed were yellowing leaves, sprout collapse, stunted growth, and leaf spot.

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.

Abstract

Background: Industrial forest plantations, particularly Eucalyptus pellita, are widely cultivated for pulp and paper production. However, nurseries of E. pellita, including those in the R&D facilities of PT Arara Abadi, are frequently infested by pests such as Strepsicrates sp. Synthetic pesticides are commonly applied to manage these infestations, although their use may pose risks to the environment. As an alternative, botanical pesticides derived from Annona muricata leaf extract have gained attention. Therefore, this study aimed to evaluate the effectiveness of A. muricata leaf extract in controlling Strepsicrates sp. and to determine its optimal concentration for application in E. pellita nurseries. Methodology: The experiment employed a completely randomized design (CRD) consisting of four treatments with five replicates. Data were analyzed using Duncan’s New Multiple Range Test (DNMRT) at a 5% significance level. The treatments consisted of concentrations of 10 g/L, 20 g/L, 30 g/L, and 40 g/L. Observed parameters included room temperature, relative humidity, time to initial mortality, time to 50% mortality, daily mortality rate, and total mortality. Findings: A. muricata leaf extract was effective in controlling Strepsicrates sp. on E. pellita. The results indicated that the optimal concentration was 40 g/L, resulting in the shortest initial mortality time of 5.2 hours, a median lethal time (LT₅₀) of 22.58 hours, and  a total mortality rate of 100%. Contribution: The findings of this study indicate that A. muricata leaf extract at a concentration of 40 g/L has strong potential for application as an environmentally friendly, effective, and sustainable botanical pesticide, supporting integrated pest management in E. pellita nurseries and reducing reliance on synthetic chemicals
