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

The existence of urban forests should be referred to as a place to preserve the environment, seeing from the start of the density of settlements that cause less and less space as a place to preserve the environment. The Bungin Island City Forest area in Koto Teluk Kuantan Village is one of the potential tourist destination objects to be offered when tourists visit Jalur City. The aim of this research was to examine the structure and composition of the stands in the Bungin Island City Forest, located in Kuantan Singingi Regency. The research method used systematic sampling method by collecting data directly at the research location. Variables observed were the number of individuals, diameter and height of trees. Vegetation data collection was carried out using the creation of a square plot unit measuring 20 m x 20 m with the determination of the plot location using systematic sampling with random start, namely taking sample plots systematically and randomly started. The data that has been obtained is analyzed descriptively quantitative which is done to obtain a clear picture of the state of the urban forest. The results of the study obtained 23 plant species in the urban forest of Bungin Island with the highest importance value index (INP) is duku plant with a value of 47,10 at the tree level, which means that this plant is the dominant species in the urban forest of Bungin Island. The conclusion of this study shows that the urban forest of Bungin Island is composed of 23 species grouped in 20 families and the composition of the stand is composed of 228 plants with the highest canopy statification in stratum C (subcanopy) followed by stratum B (canopy), stratum D (understory) and stratum A (emergent).

Abstract

Gajah sumatra adalah salah satu sub spesies gajah asia yang masih hidup di Indonesia, Sub spesies ini masuk kategori sangat terancam punah (critically endangered) menurut IUCN. Kawasan hutan sebagai home range gajah pada saat ini banyak berubah fungsi menjadi lahan perkebunan, pemukiman dan jalan, menyebabkan terjadinya konflik gajah dengan manusia. Dampak konflik gajah dan manusia tidak jarang menimbulkan kerugian-kerugian baik dari pihak manusia maupun gajah. Salah satu daerah yang sering terjadi konflik gajah adalah Giam Siak Kecil. Tujuan penelitian ini adalah Mengumpulkan informasi mengenai kondisi masyarakat, pengetahuan, dampak ekonomi, sikap, perilaku dan pandangan, serta informasi mengenai sebaran gajah sumatra, intensitas dan mitigasi konflik gajah sumatra. Pengumpulan data menggunakan metode wawancara menggunakan grid 5 x 5 km2, setiap grid terdiri dari tiga orang responden dengan kriteria minimal bertempat tinggal dua tahun di daerah tersebut. Data dianalisis secara deskriptif kualitatif. Hasil penelitian ini menunjukkan bahwa masyarakat Giam Siak Kecil pada umumnya mengetahui tentang gajah dikarenakan mayoritas masyarakat mempunyai pekerjaan sebagai petani dan gajah sering berada di wilayah perkebunan masyarakat yang mengakibatkan konflik antara masyarakat dan gajah. Masyarakat Giam Siak Kecil umumnya memandang gajah sebagai satwa yang berbahaya dan hama untuk perkebunan. 67 orang yang diwawancarai terdapat 27 orang yang berdampak ekonomi dan 40 orang tidak berdampak. Sebaran gajah sumatra di Giam Siak Kecil meliputi 14 desa, intensitas konflik gajah dengan manusia tahun 2022 sebanyak 19 kali.

Abstract

This study aims to evaluate the sustainability level of management of the Kepau Jaya Special Purpose Forest Area (KHDTK) in Kampar Regency, Riau Province, based on four main dimensions: ecological, economic, socio-cultural, and legal and institutional. The analytical method used was Multidimensional Scaling (MDS) with the Rap-SPFA tool, which was modified to assess multidimensional sustainability status. The analysis was conducted by measuring the sustainability index of each dimension using a scale of 0-100. The results showed that the overall level of sustainability was in the less sustainable category with an index of 49.56. The ecological, economic, and legal and institutional dimensions are the main focus in management, while the socio-cultural dimension is in the moderately sustainable category with an index of 68.03. The proposed sustainable management strategies include ecosystem-based zoning, utilization of non-timber forest products (NTFPs), increased community involvement, and institutional strengthening through inter-stakeholder synergies. Improving infrastructure, NTFP-based economic development, and community education are prioritized in an effort to support more effective management. The implementation of this strategy is expected to improve the sustainability of Kepau Jaya KHDTK management while improving the welfare of the surrounding community
