Abstract

Nagari Simawang has strong agricultural potential, yet the community faces limited yard utilization, dependence on costly chemical inputs, and low awareness of sustainable farming practices. This community service program aimed to enhance the knowledge and skills of residents, particularly women’s groups (PKK) and farmer groups, through practical and eco-friendly agricultural innovations. Activities were conducted in January 2026 using counseling, demonstrations, and participatory training. The program introduced three innovations: (1) microgreens cultivation using cocopeat media for limited spaces; (2) liquid organic fertilizer production from rice washing water and onion peel waste; and (3) botanical pesticide preparation from mature papaya leaves. The results indicated high participant enthusiasm, active engagement, and improved ability to independently apply the introduced techniques. In addition, participants gained greater awareness of household waste utilization and sustainable farming systems. Overall, these simple technologies proved practical and effective in strengthening household food security, reducing production costs, and promoting environmental sustainability in Nagari Simawang. Keywords: microgreens, liquid organic fertilizer, botanical pesticide, food security, sustainable agriculture

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.

Abstract

This study aims to analyze biomass quantity, carbon reserves, carbon sequestration, and to determine the environmental value of carbon sequestration in the agroforestry area of LPHN Sungai Buluh Padang Pariaman. This is because agroforestry areas can also play a role in carbon sequestration in addition to their economic function for the community. This study was conducted using purposive sampling to determine the location of 30 observation plots. Data collection was carried out using destructive sampling for undergrowth and litter data and non-destructive sampling for tree and sapling strata data. The results of this study were a total biomass of 280.768 tons/ha, total carbon reserves obtained from the biomass value of 131.955 tons/ha, and total carbon sequestration of 484.294 tons/ha. Meanwhile, the environmental service value of carbon sequestration was IDR 82,566,423,881.28/ton/year. The environmental service value obtained from this research location is relatively low compared to studies conducted in other locations, primarily due to the limited vegetation types and small study area.

Abstract

Ecosystem condition, biomass, and carbon storage in mangrove forests are highly dependent on the presence of mangrove species in coastal ecosystems. Conversely, the presence of a dominant species alters ecosystem mechanisms; for example, Nypa fruticans Wurmb. Biomass, carbon storage, and potential carbon sequestration were estimated in a coastal area dominated by N. fruticans. Sampling was conducted by laying out multi-level plots along transect lines representing different vegetation types. Biomass on the ground surface was calculated by applying species-specific allometric equations to convert biomass to carbon and CO2 equivalents, and then computing the total carbon stocks. Biomass was calculated at 140.21 tons/ha, with a carbon stock of 66.11 tons/ha, yielding a carbon sequestration potential of 241.82 tons/ha. It is obvious that N. fruticans, the dominant species as the biggest carbon store, is accompanied by low diversity of native mangrove species. Ecological imbalance between N. fruticans and other species persists despite increased total carbon storage. Management efforts must be implemented to support biodiversity and carbon sequestration in coastal mangrove forests. Keywords: biomass, carbon stock, mangrove, Nypa fruticans, carbon sequestration

Abstract. Solfiyeni, Syamsuardi, Chairul, Mukhtar E. 2022. Impacts of invasive tree species Bellucia pentamera on plant diversity, microclimate and soil of secondary tropical forest in West Sumatra, Indonesia. Biodiversitas 23: 3135-3146. The invasion of alien species in a region can alter species diversity. Bellucia pentamera Naudin is considered an alien invasive plant that has spread from Mexico to tropical America, and it is now invading some areas in Indonesia, including the tropical forest of Sumatra. Yet, the effects of its invasion on vegetation and the abiotic environment are not yet well understood. The objective of this study was to investigate the impacts of B. pentamera on species diversity and structure of vegetation, and microclimate and soil conditions of secondary tropical forests in West Sumatra. Vegetation analysis was conducted in secondary forest Bukit Tengah Pulau, South Solok, with three levels of dominance of B. pentamera namely: site 1 and 2 (60% and 16% dominance of B. pentamera respectively) and site 3 (no individual of B. pentamera). Sampling was conducted using a nested plot to collect data for tree, sapling and understorey vegetation for each site. The results showed the total number of tree species at sites 1, 2, and 3 were 23 species, 46 species, and 74 species respectively. For sapling, 20 species were found at site 1, 31 species at site 2, and 58 species at site 3. For understorey plants, 13, 16 and 36 species were detected at site 1, 2 and 3 respectively. The number of species at tree and sapling levels differed significantly among sites. The basal area also differed significantly among sites but not for sapling level. Site 1 was dominated by B. pentamera with Important Value Index (IVI) 130.8%), followed by Croton argyratus (27.63%), and Ficus variegata (26.47%). At site 2, B. pentamera dominated with IVI of 33.68%, followed by Lepisanthes sp. (20.01%) and Sizygium sp. (14.44%). Site 3 was dominated by Palaquium warsurifolium with IVI of 21.15% followed by Croton argyratus (20.02%) and Macaranga hypoleuca (13.21%). Diversity index (H') for tree-level was moderate at site 1 (H' = 1.78) and high at sites 2 and 3 (H' = 3.48 and 4.05). Similarly, the index for sapling was moderate at site 1 (H'= 2.12) and high at sites 2 and 3 (H'= 3.22 and 3.84). For understorey, the diversity index was low at site 1 (H'= 0.82) and moderate at sites 2 and 3 (H'= 1.8 and 2.86). Sites invaded by B. pentamera had a lower soil water content and higher temperature and light intensity, although they had higher nitrogen and phosphorus contents. Our findings suggest that the invasion of B. pentamera had negative impacts on plant biodiversity and microclimate, yet the impact was not clear cut on the soil.

Abstract. Solfiyeni, Mukhtar E, Syamsuardi, Chairul. 2022. Distribution of invasive alien plant species, Bellucia pentamera, in forest conservation of oil palm plantation, West Sumatra, Indonesia. Biodiversitas 23: 3667-3674. Bellucia pentamera has been found in disturbed forests across Indonesia, but little is known about how it spreads under its tree canopy. The spread of the invasive plant B. pentamera in the PT KSI conservation forest area was investigated. The goal of this research is to study B. pentamera's strategy for exploiting forest gaps horizontally and vertically on degraded forest vegetation invaded by B. pentamera at various degrees of invasion. An Unmanned Aerial Vehicle (UAV) and direct field mapping are used for the mapping approach. Aerial photographs revealed 40 B. pentamera trees and 32 non-B. pentamera trees in forest areas with varying degrees of B. pentamera invasion (based on the ratio of B. pentamera non-B. pentamera: dense and loose). Bellucia pentamera trees were distributed evenly in a large gap and randomly in a small gap/space between the canopy, whereas sapling and seedling B. pentamera trees were distributed in groups, uniformly and randomly, according to microhabitat conditions under the canopy of B. pentamera and non-tree trees. Bellucia pentamera seedlings and saplings were detected under the parent tree's canopy rather than in the canopy gaps. Different responses were seen in seedlings, saplings, and juvenile stages concerning the explanatory factors investigated and between the two stands. The purpose of the study was to determine the factors that influence the distribution of the B. pentamera species in conservation forest areas with different compositions of existence, both vertically and horizontally, using drones and direct measurements in the field.

Abstract. Solfiyeni S, Fadhlan A, Aziz A, Syahputra G, Azzahra A, Mildawati M. 2024. Vegetation diversity and habitat suitability modeling of the invasive plant Bellucia pentamera in Conservation Forests of West Sumatra, Indonesia. Biodiversitas 25: 781-791. The invasive plant Bellucia pentamera has spread to several regions in Indonesia, including the province of West Sumatra. Mapping the distribution of this invasive plant needs to be done to facilitate its management. offers a comprehensive approach to delineate the potential ecological range of a species and assess habitat suitability. This study aimed to evaluate the impact of B. pentamera invasion on vegetation diversity, conduct potential distribution mapping, and assess B. pentamera habitat suitability in West Sumatra conservation forests. The study utilized observational methods to determine coordinate points for B. pentamera presence and conducted vegetation analysis. The results from the vegetation analysis revealed disparities in composition and structure across three study areas, with diversity indices ranging from 2.60 to 3.84. The similarity index between study areas was relatively low, below 50%. The MaxEnt analysis delineated suitable locations for B. pentamera using the ROC curve (AUC) model, yielding values of 0.947 for training data and 0.923 for testing data. MaxEnt modeling identified suitable habitat for B. pentamera concentrated at Lima Puluh Kota, Tanah Datar, Padang, Solok and South Solok districts. This study's findings indicate a broad distribution of this species, with over 5% of the habitat deemed suitable for B. pentamera.
