Abstract

Sentajo Protected Forest located in Kuantan Singingi Regency, Riau Province. There is no information about vegetation diversity in this location. Therefore this study was conducted. This study aimed to determine the diversity of vegetation, structure, and composition of each community in Sentajo Protected Forest. The study was conducted in April-September 2016. A sampling design was determined using systematic sampling with random start. The sampling intensity used was 5%. The parameters measured in this study were the importance value index, similarity index between communities, species diversity index, evenness index, dominance index, regeneration, as well as horizontal and vertical structures. Based on the type of soil, elevation, and slope, 6 communities were grouped from the dense coverage area (forested). The results showed that the Sentajo Protected Forest had 424 flora consisted of 254 species, and 102 families. Sentajo Protected Forest had similarity index between 18 - 64%, species diversity index of 2.62 - 4.15, evenness index of 0.59 - 0.86, dominance index of 0.02 - 0.08. The larger the diameter of the tree, the smaller the number of individuals. The stratification of the canopy had 5 layers of canopy. Sentajo Protected Forest regeneration was relatively good as the number of seedlings> saplings> mature trees.Key words: community, composition and structure, diversity, Sentajo Protected Forest.

Abstract

Tin mining activities in Siabu Village, Salo District, Kampar Regency, have environmental impacts, leading to soil pollution by heavy metals, particularly lead (Pb). This study aims to evaluate the potential and growth of five plant species (A. mangium, P. falcataria, S. macrophylla, I. cylindrica, and M. malabathricum) in phytoremediation of soil contaminated with lead from tin mining. The research employed a completely randomized design with five treatments and four replications, totaling 20 experimental units. Data were analyzed using SPSS 20.0, and if significant, further analysis was conducted using Duncan's New Multiple Range Test (DNMRT) at a 5% level of significance. The results of the research that had been conducted showed that the five types of plants had the potential to absorb the heavy metal lead (Pb) but with different absorption concentration levels. The highest absorption of lead (Pb) in the seedling group was P1 (A. mangium) treatment with the ability to absorb Pb metal at 6.33 ppm and the remaining Pb metal content in the soil of 14.18 ppm, while the absorption of heavy metal lead (Pb) which was highest in the lower vegetation group was treatment P5 (M. malabathricum) of 9.10 ppm with the remaining Pb metal content in the soil of 7.75 ppm.

Abstract

Acacia crassicarpa is one of the Fabaceae family which has been widely recommended for planting in the context of rehabilitation of critical lands as well as HTI development, due to its fast growth, wide adaptation, and resistance to unfavorable conditions. Acacia crassicarpa in the nursery is often attacked by various pests, one of which is the Paracoccus marginatus. Efforts to the use of Annona muricata leaf control Paracoccus marginatus currently carried out generally use chemical methods. extract is an alternative that can be used as an environmentally friendly pesticide. This study aims to determine the utilization of Annona muricata leaf extract to control Paracoccus marginatus in Acacia crassicarpa nursery and to determine the best concentration of Annona muricata leaf extract for the mortality rate of Paracoccus marginatus. This study used a completely randomized design method (CRD) consisting of 4 treatments and 4 replications with concentrations of vegetable pesticide solutions. P0 = control (without Annona muricata leaf extract), P1 = 10 g/l of water, P2 = 20 g/l of water, P3 = 30 g/l of water. The results showed that the botanical pesticide from Annon muricata leaf extract concentration of 30 g/l of water is the best concentration in controlling Paracoccus marginatus with the fastest initial time of insect death is 2.5 hours (2 hours 30 minutes), 50% fastest time of death (LT50) is 8.5 hours (8 hours 30 minutes) and total mortality amounted to 90 %.

Abstract

Nepenthes is a unique carnivorous plant, both in terms of shape, color and how to get food. The purpose of this study was to determine the diversity of Nepenthes species and determine how the characteristics of Nepenthes habitat in the Harau Valley Nature Reserve. This research has been conducted in December 2023 in Harau Valley Nature Reserve. The method used in the research was direct observation method with purposive sampling technique by making 20x20 meter plot in natural forest, and 2x2 meter plot in shrubs. The parameters observed were the number of Nepenthes found in each plot, temperature, air humidity, soil pH and light intensity. After identifying the species, 3 species of Nepenthes were found, namely Nepenthes albomarginata, Nepenthes eustachya, and Nepenthes gracilis with a total of 160 individuals. For the results of measurements of physical environmental factors in natural forests, the average temperature was 24.70°C, humidity 83.90%, soil pH 5.60 and light intensity 2882 lux, while in shrubs the average temperature was 27.90°C, humidity 74.3%, soil pH 5.20 and light intensity 3679 lux.

Abstract

Lebah Kelulut merupakan lebah tanpa sengat penghasil madu dari famili Apidae, hidup berkoloni 300-80.000 ekor terdiri dari ratu, jantan, dan pekerja. Ketersediaan pakan berkelanjutan penting untuk perkembangan koloni dan produksi madu, bersumber dari nektar, polen, dan resin. Penelitian ini bertujuan mengkaji karakteristik habitat dan sumber pakan lebah kelulut di Desa Baturijal Hulu, Kecamatan Peranap, Kabupaten Indragiri Hulu. Metode observasi lapangan menggunakan petak contoh untuk analisis vegetasi dan data habitat meliputi suhu, kelembapan, dan intensitas cahaya. Hasil penelitian menemukan tiga jenis lebah kelulut—Heterotrigona itama, Tetragonula leaviceps, dan Geniotrigona thoracica—dengan 90 koloni yang dibudidayakan dalam stup kayu dan log alami. Sumber pakan terdiri dari 30 jenis tanaman berbunga. Kondisi habitat di Desa Baturijal Hulu mendukung pertumbuhan koloni, berpotensi tinggi untuk budidaya lebah kelulut. Kata kunci: Lebah kelulut, koloni, habitat, sumber makanan, budidaya
