Abstract

The presence of invasive plants in a habitat will cause significant disturbances, especially in decreasing the abundance of biodiversity. The high competitiveness of invasive species causes native species to lose in competition. Invasive species have spread in many places, one of which is in the Bukit Langkisau City Forest. However, data on the types of weeds and vegetation types in the habitats invaded by weeds in the Bukit Langkisau City Forest are not yet available. Vegetation analysis was carried out in the Bukit Langkisau Painan City Forest, West Sumatra. The study used a survey method by laying out plots by purposive sampling, which made 15 plots at each level of vegetation. The plot is 10 x 10 m for observation of tree-level vegetation, the plot is 5 x 5 m for sapling vegetation and for understorey vegetation the plot is 2 x 2 m. The results of the vegetation analysis recorded 87 species of which there were 32 invasive species. The dominant families were found such as Fabaceae family, Meliaceae for tree level, Piperaceae for sapling level and Poaceae for understorey level. The highest Importance Value Index for tree vegetation, sapling and understorey was found in the invasive species Swietenia macrophylla (IVI = 44.69%), Piper aduncum (IVI = 85.08%), and Imperata cylindrica (IVI = 33.67%). The Vegetation Diversity Index in the Bukit Langkisau City Forest is the tree level (1.90), sapling (1.26) and understorey (1.78) which are all classified as moderate. KEYWORDSPlant invasive, urban forest, composition, structure, diversity index

Abstract

The Silokek Geopark area, Sijunjung Regency, is one of the tourist areas in West Sumatra Province which has a high level of biodiversity, which can be disrupted due to the presence of invasive plants. A study has been carried out which aims to determine the composition and structure of undergrowth in habitats invaded by weeds in the Silokek Geopark tourist area, Sijunjung Regency. This research was conducted from September to December 2022 using the quadratic method and plotting by purposive sampling with a plot size of 10 x 10 m with a sub-plot measuring 2 x 2 m. The composition of undergrowth in the habitat invaded by weeds found 24 families, 38 genera, 38 species, and 1049 individuals. Among the undergrowth found, there were 12 families, 20 genera, 20 species and 532 individuals of invasive plants with the dominant family being Asteraceae (30.41%), and the co-dominant family being Nephrolepidaceae and Poaceae with a percentage of 17 each. .83% and 11.63%. The highest important value index was in Nephrolepis biserrata (28.42%) and the lowest was in Musa acuminata (0.76%). The most dominant weed species was Mikania michranta with an IVI of 18.79%. The diversity index of the understorey plants in this area is categorized as high with a diversity index (H' = 3.24). Weed plant species are more successful in dominating open and disturbed areas with high levels of light intensity, gaps or wide gaps and forest edges can be utilized by invasive plant species to grow optimally.

Abstract

Bellucia pentamera Naudin, the proliferation across Indonesia, notably in Sumatra, has the potential to lessen biodiversity there. On the other hand, little is known about the effects of its invasion on plants and the ecology. The objective of this study was to evaluate the genetic makeup and structural characteristics of saplings and the understorey vegetation in the B. pentamera-infested Lembah Harau sanctuary forest zone. Vegetation analysis was conducted in the sanctuary Lembah harau forest with two levels of dominance: Station 1 was lightly invaded by B. pentamera, and Station 2 was heavily invaded by B. pentamera. Purposive sampling is used in the plot method. The findings found that the number of sapling species at stations 1 and 2 was 18 and seven, respectively. Station 1 had 38 species of understorey, while station 2 had 26. The Melastomataceae family dominated the sapling strata and understorey at stations 1 and 2. The B. pentamera species has the highest Important Value Index sapling at Stations 1 and 2. While in the understorey, station 1 has the highest Importance Value Index (24.45%) and the highest B. pentamera species (59.10%). Both stations have a moderate Diversity Index (H') for sapling and understorey levels. The Community Similarity Index (IS) of sapling and plant levels at stations 1 and 2 is relatively low.

Abstract

Threats that can cause loss of biodiversity include the presence of invasive foreign plants. One of these invasive plants is from the Melastomataceae family with the species Bellucia pentamera Naudin, and this species can trigger a decline in ecosystem diversity. B. pentamera contains a chemical compound that can be used as an herbicide, phenolic, and flavonoid compounds, which can retard the growth of other plants that surround them like noxious weeds. Bioherbicides need to be used as an environmentally friendly alternative drug control method to overcome and reduce their adverse effects. This research was carried out to determine the impact and concentration of administering B. pentamera leaf extract on the germination and growth of Chromolaena odorata. The study used experimental methods with a completely randomized design (CRD) with six variations consisting of treatment of 0, 10, 15, 20, 25, and 30% with a four-time repetition. The research results showed the effect of giving greater concentrations of B. pentamera leaf extract, causing the germination and growth of C. odorata to be increasingly hampered. Providing extracts with concentrations of 20% and 25% are effective for inhibiting the germination and growth of C. odorata.

Abstract

Plant extracts are one biostimulant sources that have the potential to increase plant growth and yield. Portulaca contains secondary metabolites, macro and micronutrients, and amino acids, which have the potential as biostimulants. The research aims to determine the best type of solvent in the Portulaca extraction process as a biostimulant. The method used in this study was a Completely Randomized Design (CRD) with three treatments (aquadest, ethanol, and methanol) and nine replicates. The application of Portulaca extract extracted with several solvents significantly affected root length parameters of kale, with the most extended the root length of 15.80 cm. However, it did not have a significantly different effect on other parameters. Based on the proximate analysis, Portulaca extract extracted with ethanol solvent produces a protein content of 25.26%.

Abstract

The utilization of rice washing water waste from households has not been optimized, even though it contains a large amount of essential nutrients for plant growth. This waste can be utilized as natural fertilizer for horticultural plants. Rice washing water provides various benefits for plants, is easily accessible to farmers, and is also environmentally friendly. Additionally, its price is very affordable so it can be accessed by farmers. The purpose of this activity is to increase knowledge and understanding of the community in making Liquid Organic Fertilizer (LOF) derived from rice washing water waste, as well as to reduce the use of chemical fertilizers by shifting to organic fertilizers to maintain soil and environmental quality. This activity was conducted in Nagari Lawang, Matur District, Agam, West Sumatra. The method used was through lectures and demonstrations of liquid organic fertilizer (LOF) production. The results of this activity showed that the interaction between the organizers and participants had a positive impact, improving skills, and motivating PKK mothers in plant cultivation. The home garden is seen as a productive land for nutrition and income, but there are obstacles such as lack of knowledge and capital. Overcoming these obstacles requires increasing technical knowledge and providing capital. Furthermore, this activity also resulted in increased knowledge and active participation in the process of making liquid organic fertilizer. The conclusion of this activity is to increase knowledge and skills in making LOF, motivating intensive plant cultivation. Public interest in making LOF from waste is high, increasing knowledge and skills in producing organic fertilizer for successful plant cultivation.
