This study aimed to determine the antimalarial effect of the Strychnos ligustrina (SLW) wood extracts and to analyze its phytochemicals. The SLW powder samples were macerated with 100% ethanol (E100), 75% ethanol (E75), 50% ethanol (E50), 25% ethanol (E25), and aqueous (A100). The extracts were analyzed by LCMS/MS, and its in-vitro antimalarial activity was tested with Plasmodium falciparum. The results showed that the extract yields of E100, E75, E50, E25, and A100 were 4.3, 5.2, 5.3, 4.7, and 3.6%, respectively. The antimalarial activities of the A100, E25, E50, and E75 extracts were classified as active with IC 50 values of 38.6, 42.6, 42.9, and 43.7 μg/mL, respectively. But, the antimalarial activity of the E100 extract was classified as slightly active with IC 50 values of 87.4 μg/mL. The dominant compounds contained in the extracts of A100, E25, E50, E75, and E100 was the alkaloid compound,
Village life around the forest is inseparable from the existence of the forest. The use of raru as a forest product has been passed down from generation to generation in the community of Bonalumban Village, Tukka District, Central Tapanuli Regency, North Sumatra. The study of community perceptions and dependencies on Raru in Bonalumban village is needed to determine the potential of raru and encourage efforts to preserve raru. The method of selecting respondents is done by purposive sampling by selecting general respondents and specialized respondents. Data analysis uses descriptive statistics. Public perceptions about the existence of raru in nature are still plentiful so there is no public effort to regenerate. Community dependency on raru is grouped into four categories, that is for sale, palm wine concoctions, animal cages, and building materials. Raru harvesting activities by felling without being accompanied by cultivation activities causes the presence of raru vegetation to decrease.
The Pondok Buluh Training Forest is located in Simalungun Regency, North Sumatra, which has a fairly high diversity of flora, one of which is a plant from the Araceae family. Araceae is a family of taro that has potential for ornamental plants, medicinal plants, food and animal feed, therefore it is important to conduct research on Araceae species in this location to determine the diversity and potential of Araceae. From the results of the research, it was found that there were 13 species of Araceae which were included in 6 genera, namely Aglaonema, Alocasia, Diffenbachia, Homalomena, Schismatoglottis and Syngonium. The species are Aglaonema crispum, Alocasia arifolia, Alocasia sp., Alocasia longiloba, Alocasia sanderiana, Alocasia scabriuscula, Dieffenbachia seguine, Diffenbachia amoena, Homalomena cordata schott, Homalomena pendula, Homalomena rubescens, Schismatoglottis calyptrata, and Syngonium podophyllum. The potential of Araceae plants is as a medicinal plant, ornamental plant, vegetable pesticide and animal feed.
Desa Ria-Ria Kecamatan Pollung Kabupaten Humbahas, dipilih dan dipersiapkan sebagai lokasi dosen wajib mengabdi dari Universitas Sumatera Utara dalam program food estate dengan menerapkan sistem agroforestry melalui pola agrosilvopastural (ternak, kehutanan, dan pertanian). Humbang Hasundutan berpotensi karena terletak didataran tinggi yang memiliki curah hujan yang sangat tinggi dan agroklimat yang sesuai untuk budidaya holtikultura, oleh sebab itu agrosilvopastur cocok diterapkan. Sistem agrosilvopastur diharapkan dapat meningkatkan produktivitas lahan secara keseluruhan dan berkelanjutan yang dapat menjamin dan memenuhi kebutuhan hidup masyarakat petani. PKM ini dilaksanakan tanggal 20 November 2021 yang bertempat di kantor kepala desa Riaria Kecamatan Pollung, yang dihadiri anggota kelompok tani agrosilvopastur maju karya sebanyak 24 orang angggota kelompok. Hasil bersama mitra nantinya selain dapat memasarkan produksi rumput sebagai hijauan pakan ternak juga akan mampu memasarkan daging seiring dengan meningkatnya kebutuhan pasar daging dalam negeri. Dari kegiatan dosen wajib mengabdi, dapat memberdayakan petani dalam bidang agrosivopastural, peningkatan pendapatan, dan sekaligus kesejahteraannya
Abstract. Spinal fracture and dislocation are among the most feared injuries by patients and physicians alike, as the consequences can be devastating, ranging from mild pain and discomfort to severe paralysis and even death. Spinal trauma is commonly found in patients admitted to level-one trauma centers after serious accidents like traffic, falling, and sports accidents.Injuries of the cervical spine account for one third of spinal fractures and half to two thirds of all spinal cord injuries.In the thoracolumbar spine, the most common unstable fracture is the burst fracture. Altogether, burst fractures have been reported to account for about 15% of spinal injuries.Incidence of burst fractures peaked at the thoracolumbar junction and between levels T5 and T8. In 10% of cases,more than one burst fracture was seen, thereof 53% on noncontiguous levels. Main accident mechanisms were falls, traffic, and sports. Neurological deficit was highest in patients with burst fractures of the cervical spine, independent of accident mechanism, and lowest in thoracolumbar junction fractures. Burst fractures occur frequently in high energy traumas and are most commonly associated with falling and traffic accidents.Multiple burst fractures occur in 10% of cases, half thereof on noncontiguous levels.Access to the anterior thoracic spine via the transthoracic approach (via thoracotomy) can be used for decompression and fusion. To perform adequate decompression and stabilization of the thoracic spine, obtaining good exposure is a must. Preservation and protection of the vascular structures in the thoracic cavity is the key to such an exposure. Preoperative workup should include imaging modalities (plain rontgens, MRI/CT scan) to specifically define the area of decompression. If a tumor is being evaluated, CT angiography and embolization are helpful in preoperative planning. Assistance by a thoracic surgeon for exposure is highly recommended.
Indonesia is one of the countries with the highest biodiversity in the world. Forests are very diverse flora habitats. One of them is the diversity of understorey plants found in the Pondok Buluh Education and Training Forest Simalungun, North Smatra. The purpose of this study was to determine the diversity of understorey vegetation species found in the Pondok Buluh Education and Training Forest. This research method is by means of analysis of understorey vegetation with a size of 2x2 m with a total of 45 plots. There are 30 species of understorey found in the Pondok Buluh Education and Training Forest which consists of 13 families, namely Araceae with 12 species (40,00%), Arecaceae comprised 4 species (13.33%), Zingiberaceae 3 species (10.00%), Poaceae 2 species (6.67%), and Asteraceae 1 species (3.33%). Based on the use of understorey plants, 12 species (40%) are included in ornamental plant species, 12 species (40%) were included in medicinal plants, 3 species (10%) are included in handicrafts, 1 species (3.3) %) is included in the species of vegetable pesticide 1 species (3.3%) is included in the animal feed plant and 2 species (6.66%) utilization has not been identified.
The Universitas Sumatra Utara campus is included in a green campus. Identification of medicinal plants in a campus environment that has a large enough green open area is important to know the types that exist. The identification results can be used as a reference in the future to enrich medicinal plants around the campus and open up the knowledge of the community around the campus the importance of medicinal plants to be cultivated. This study aims to make an inventory of medicinal plants in the University of North Sumatra campus environment and the benefits of medicinal plants found. The method of collecting medicinal plant species was carried out by exploring the campus of the Universitas Sumatra Utara. There are 21 types of medicinal plants found on the campus of the University of North Sumatra. Medicinal plants, which are often used by the Indonesian people as spices or flavouring mixtures in cooking, include tamarind (Tamarindus Indica L), balanced (Solanum torvum Sw), coconut (Cocos nucifera L.), pandanus (Pandanus amaryllifolius) and lemongrass (C. citratus).
