Abstract

Alstonia scholaris is one of the plant indigenous and able to grow rapidly. In the application of fertilizer should be can improve the yields a plant including Alstonia scholaris. Solutions offered as used fertilizer local, the use of waste as fertilizer need to be improved. One of effective way is to take advantage of waste rubber (leaves) be the fertilizer the form of liquid smoke. The purpose of this research is to determine the growth seedling Alstonia scholaris by administering liquid smoke of litter leaves rubber as fertilizer liquid. This study conducted by the method of the Complete Random Design (CRD) with 4 treatment 3 times repeat with each experiment consist of 10 plants so obtained 120 units plants. The results that the application of liquid smoke influential growth seedling Alstonia scholaris dose is best P2 (3 ml/L water), by showing the result of 100% percent of life seedling, growt of plant height is 16,98 cm and dry weight of plant is 29,97 g.

Abstract

Antochephalus cadamba is a local Indonesian plant that grows very fast and can thrive in tropical forests. Good quality Antochephalus cadamba seeds are needed to make sure the success of the planter and good results. Local Micro Organism (LMO) is a solution of the decay of organic materials derived from plant residues, animal feces, and humans, which contain more than one element. Local Micro Organisms are micro-organisms that are used as starters in making solid organic fertilizers and liquid fertilizers. The aim of the study was to find the effect of Local Micro Organism fertilizer on the growth of Antochephalus cadamba seedlings and the best dose of LMO fertilizer to trigger the growth of seedlings. This research was carried out with an experimental method using a non factorial Completely Randomized Design, LMO fertilizer consisting of five treatments with four replications, to get twenty experimental units. The results that the application of LMO fertilizer on the growth of Antochephalus cadamba dose is best 60 cc/plant, by showing the result of 100% percent of life seedling, growt of plant height is 15,03 cm and dry weight of plant is 35,11 g.

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.
