Research on invasive plant diversity in Sultan Thaha Syaifuddin Forest Park area has been done from July - sepetember 2017 by quadraticmethod. The plot is placed by purposive sampling consisting of 52 plots with a plot size of 5m x 5 m. The result of this research showed that invasiveplant composition was 7 families, 9 species and 1.775 individuals. Clidemia hirta has the highest important index value of 51.53% and Acaciamangium has the second highest important value index after Clidemia hirta is 34.46%. The diversity index of invasive plants is H '= 1.8. Clidemiahirta is a weed and invasive plant growing on agricultural land, logged over and an aggressive pioneer species due to its rapidly germination ofseeds, which invade open spaces, landslides, roadsides, paths, logged-over fields and humps forest and can grow fast and tolerant to shade. Acaciamangium is the second dominant species found after Clidemia hirta. Acacia mangium is known by the name of acacia, its rapid growth, good qualityof wood and its tolerant ability to various kinds of soil and environment.Keywords: composition, invasive aliens species, structure

Research studies on the composition of basic vegetation in Sultan Thaha Saifuddin Grand Forest Park area have been conducted from July to August 2018 with multiple plot vegetation method.. The plots placement was done by purposive sampling at two different land cover locations. The plot size sampling was 10x10 meters, 8 plots were located at the burnt location and 5 plots at the location of the bulian natural habitat. The results of the study found 37 families, and 80 species, where the family that has the highest number of species is the Moraceae family which is as many as 6 species. Plant species found in burned areas were 48 species, in non-burnt areas (bulian habitat) 29 species and in post-burned and non-burned area as many as 3 species.

Indonesia has approximately 30,000 species of medicinal plants based on the richness of the flora. Indonesia has the great potential to develop herbal products that are equivalent to modern medicine. The modern treatment has not been reachable by the whole community in Indonesia, only about 25% affordable and the rest are not yet affordable. The role of traditional medicine recipes become much helpful especially for people living in remote areas with minimal access. The research was conducted in April-May 2019 at Talang Rencong Traditional forest, Pulau Cage Village, Kerinci Regency, Jambi. The sample area of research was 1 Ha, or 5% of total area. The methods used in this research were participatory exploration and observation, data collection was conducted by tracing indigenous forests accompanied by local communities (Data is analyzed from any species found during research). The research in the indigenous forest Talang Rencong village Pulau Cage, Kerinci Regency, Jambi acquired 23 familia and 39 species of medicinal plants used. How to use from the herbs are divided into 25 species of medicinal plants that use drinkable, 6 species of medicinal plants are applied or pasted, 4 species of herbs are directly consumed, 1 species of medicinal plants is used to be washed, 2 species of medicinal plants used to be dipped in the eyes and 1 type of medicinal plants that use the input into perforated teeth The benefits of such medicinal plants are as breast cancer medicine, relieves itching for children, nail health remedy, uric acid medecine, removal bruising, uterine watering, appetite enhancer, diarrhea, toothache medications, jaundice medications, cough medicines, shortness of breath medication for infants, deep heat medications, reducing blood sugar levels, paralysis medications, lowering cholesterol, and medication for postnatal blood and uric acid.

Lowland forest vegetation can still be found on the Jambi University Campus, namely at the Jambi Mendalo University Educational Forest (HPUJM). Jambi University Educational Forest is administratively located in Mendalo Indah Village, Jambi Luar Kota District, Muaro Jambi Regency, Jambi Province. Vegetation communities are formed by the presence and interaction of the various types of plants that compose them. The form of interaction between plant species in a community is called an association. Associations can be in the form of positive associations and negative associations. This research was conducted to know the association between dominant tree species. This study used a purposive sampling method by determining a sampling area of 9600 m2 or 0.96 ha measuring 160m x 60m, divided into 24 sub-plots, each measuring 20m x 20m. Species having an Importance Value Index (IVI) of ≥ 10% were used as the association analysis. The 2x2 contingency table was used to analyze whether or not associations were present between tree species. The results showed, of 15 dominant tree combinations, there were only 4 associated combinations, namely the association between Aporosa lucida and Vitex pinnata, the association between Endospermum diadenum and V.pinnata, the association of Litsea ferruginea with Gironniera diadenum, the association of L. ferruginea with V.pinnata. Key words: association, dominant tree, lowland forest

This research was a mixed method which aimed to determine the effect of mathematical self-concept on mathematical communication skills and to describe mathematical communication skills in relation to mathematical self-concept. This research was conducted at SMP Negeri 2 Majene in the even semester of the 2021/2022 academic year. The subjects in this study amounted to 9 students of class VIII A SMP Negeri 2 Majene. The research design used was quantitative explanatory with descriptive method. The instruments in this study were tests, questionnaires, and interview guidelines. The data analysis technique used was quantitative analysis and qualitative analysis. The results of this study indicated that there was a positive and significant effect between mathematical self-concept and students' mathematical communication skills. In addition, this study also showed that subjects with high mathematical self-concept tend to be able to fulfill all indicators of mathematical communication skills including grammar skills, discourse skills, sociolinguistic abilities, and strategic abilities. Subjects with moderate mathematical self-concepts tend to be able to fulfill 3 indicators including grammar skills, discourse skills, and sociolinguistic abilities. The strategic ability indicator has not been met because the subject gave the wrong answer and was not able to explain the stages of completion. Subjects with low mathematical self-concept tend not to be able to fulfill all indicators of mathematical communication skills including grammar skills, discourse skills, sociolinguistic abilities, and strategic abilities.

The Forest of the Jambi Mendalo University Campus is one of the green open spaces in the Jambi University Campus environment and in the City of Jambi which has many functions and potential to be developed. Its main function is the source of oxygen and CO2 absorbent in the campus environment, the source of biodiversity of the germplasm of Sumatra's lowland forest ecosystems and as a means of education for students, elementary school students to high schools and the people of the city of Jambi. Until now data about existing plant species and their potential is still very limited. Existing research is limited to carbon sequestration, the distribution patterns of several tree species and the physical conditions of their environment. The study was conducted in 2019. Sample plots in the form of a single plot measuring 160 x 60 meters were placed purposively at the study site. Based on the results of the inventory and identification, there were 176 species (species), 116 genera (genera) and 55 families (families). Still found species of the Dipterocarpaceae tribe, namely Shorea leprosula, Shorea parvifolia and Parashorea sp. Of the 109 species of stadia seedlings, 58 species are classified as saplings, 23 species of shrubs, 20 types of liana, 4 types of herbs, 2 types of ferns and 2 types of palm. Keywords: The forest of the campus, permanent sample plot, The compotition of vegetation
