Abstract

Pelatihan Pengukuran Diameter Pohon untuk Menduga Kandungan Biomassa Karbon di Hutan Alam merupakan upaya kolaboratif antara Jurusan Kehutanan, Universitas Riau dan Rimba Satwa Foundation (RSF) dalam meningkatkan pemahaman dan keterampilan dalam estimasi biomassa karbon di hutan alam. Pelatihan ini bertujuan untuk meningkatkan keterampilan pengukuran diameter pohon dan kemampuan estimasi biomassa karbon bagi para mahasiswa dan anggota Rimba Satwa Foundation. Workshop dilakukan dengan metode kombinasi teori dan praktik lapangan. Peserta diberikan pemahaman tentang konsep biomassa karbon, pentingnya pengukuran diameter pohon, dan teknik-teknik pengukuran yang digunakan. Setelah itu, mereka langsung terlibat dalam praktek lapangan dengan melakukan pengukuran diameter pohon dan menghitung estimasi biomassa karbon. Hasil pelatihan menunjukkan peningkatan signifikan dalam keterampilan pengukuran diameter pohon dan pemahaman mengenai estimasi biomassa karbon. Kolaborasi antara Jurusan Kehutanan dan Rimba Satwa Foundation dalam pelatihan ini memberikan dampak positif dalam peningkatan keterampilan dan pemahaman peserta. Pelatihan ini diharapkan dapat menjadi model bagi upaya-upaya konservasi lingkungan yang melibatkan berbagai pihak terkait dan membantu dalam upaya pelestarian dan pengelolaan hutan alam secara berkelanjutan.

Abstract

Pengenalan jenis dan perawatan pohon merupakan kegiatan yang akan sangat bermanfaat untuk menambah pengetahuan anak-anak sekolah dasar, dimana pada kegiatan ini mereka akan diajarkan dasar-dasar dari pengenalan jenis pohon serta bagaimana merawat tanaman. Dengan kegiatan ini diharapkan anak-anak sekolah dasar akan lebih mengetahui bahwa pohon memiliki ciri-ciri, jenis dan karakteristik yang berbeda beda dan juga mereka akan lebih peduli dengan tanaman yang ada disekitar mereka dengan cara merawat tanaman tersebut. Kegiatan ini dilakukan beberapa tahapan yaitu pertama kali adalah observasi pengetahuan jenis dan cara perawatan pohon kepada anak-anak sekolah dasar, kemudian pemberian edukasi dan praktik secara langsung bagaimana cara pengenalan jenis pohon dan juga merawat tanaman. Kemudian yang terakhir adalah evaluasi anak-anak sekolah dasar mengenai pemahaman mereka mengenai edukasi yang diberikan dengan cara melakukan tanya jawab. Adapun kesimpulan dari pengabdian kepada masyarakat ini adalah edukasi lingkungan dapat melatih siswa untuk bertanggung jawab, mencintai alam, dan memahami pentingnya pelestarian lingkungan. Kegiatan ini tidak hanya memberikan pengetahuan teoritis, tetapi juga pengalaman praktis yang mendukung terciptanya lingkungan belajar yang berkelanjutan dan berdampak positif bagi masa depan.

Abstract

The decline in productivity of Acacia seedlings (Acacia crassicarpa) in Industrial Plantation Forests is caused in part by attacks of mealybug pests (Paracoccus marginatus). Using chemical insecticides in pest control can negatively impact health and the environment, so more environmentally friendly alternatives are needed, such as plant-based insecticides. This study aims to determine the concentration of noni leaf extract on the mortality of mealybug pests. A completely randomized design (CRD) was employed, consisting of four treatments with different concentrations of Morinda citrifolia leaf extract (30 g/l, 40 g/l, 50 g/l, and 60 g/l), each replicated three times. The observed parameters included the time of initial death, Lethal Time 50 (LT₅₀), and total mortality percentage. The results indicated that the use of Morinda citrifolia leaf extract of 60 g/l was the most effective, with an average time of 8,67 hours, LT₅₀ of 24,67 hours, and total mortality rate of 100% for Paracoccus marginatus.

Abstract

Forest degradation in river basins can cause soil erosion and landslides in upstream areas, as well as flooding in downstream areas, thereby expanding critical land areas. To reduce the extent of critical land, comprehensive forest and land rehabilitation efforts must be undertaken with the involvement of multiple stakeholders. Activities conducted in Tapung Sub-district, Kampar Regency include reforestation of the Imbo Putui Traditional Forest area, seedling planting along the Tapung River, roadside planting, school ground plantations, and similar initiatives. This research aims to identify the roles of various stakeholders in forest and land rehabilitation (RHL) activities in Tapung Sub-district, Kampar Regency. This study employs qualitative methods, collecting data through observation, in-depth interviews, and documentation studies to obtain both primary and secondary data. Data analysis was conducted using descriptive qualitative techniques. The research findings reveal that multiple stakeholders are involved in forest and land rehabilitation activities. Forest farmer groups play an implementation role in community nursery and village nursery programs to provide seedlings required for forest and land rehabilitation activities, with funding facilitated by BPDASHL Indragiri Rokan, which serves as the program initiator and supervisor. DLHK Riau Province and KPH Suligi Batu Gajah function as coordinators and facilitators in seedling procurement and distribution to communities. KODIM 0313/KPR serves as protector and activity supervisor. Community-based forestry extension officers act as catalysts, mediators, motivators, and educators within the community. Private companies also contribute as financial and material supporters through corporate social responsibility program implementation.

Abstract

The Replica of Istano Basa Pagaruyung is Minangkabau traditional house building in the form of a rumah gadang which is made with the guiding of the palace that ever existed before. Istano Basa Pagaruyung has been destroyed three times in the year 1837 due to the war, in 1996 and in 2007 due to burning. The existence and preservation of this traditional house must be maintained because it is a cultural symbol of Minangkabau society. This study aims to determine the type and criteria of wood used in making replica Istano Basa Pagaruyung based on public perception. This study uses snowball sampling method that has been implemented in October 2016 in Replica Istano Basa Pagaruyung. Criteria of wood used as raw material for reproduction of Istano Pagaruyung based on community perception that is hardwood, straight and have dark color. Under construction, the wood used should not be wet. Wood cutting system that is wood can not be felled in a flowering state, because at the time the wood has a delicious smell so favored by insects. Types of wood used are Toona sureni, Shorea leprosula Miq., Anisoptera costata Korth and Ptetospermum spp.

Abstract

Unmanned aerial vehicle is one way to get the information of spatial data that photographed in detail small objects on the land with coverage area that is not too broad. The photo shoot was done in the Riau University Arboretum and surrounding areas. The location of the photo shoot on the research including scientific development zone to study forest ecosystems, activities of Student Affairs and the place that usually visited by community. This research aims to mapping and to know the land cover in the Riau University Arboretum and to know value of the accuracy test of the aerial photography from the unmanned aerial vehicle. The aerial photography is analyzed by visual interpretation, the maximum scale based on spatial resolution and use omission commission testing accuracy to compare the value of the observed object in the field and aerial photograph. The bounderies of Riau University Arboretum is not in the field physically, so the Riau University Arboretum as a landmark. The result of the maximum scale is 1:100 with 2.77 cm spatial resolution, so it seems clear the land cover in the aerial photography i.e. vegetation, buildings, and undeveloped land. The result of accuracy test that was conducted showed that the percentage of accuracy reaches 95%, so that the data from the unmanned aerial vehicle can be utilized for mapping a region.
