Abstract

Ferns or Pteridophyta are lower plants from the Cryptogamae division, which can be distinguished between roots, leaves, and stems. Ferns have great ecological importance, namely as understory plants that contribute to the long-term sustainability of forest ecosystems by mixing soil litter, as ground cover vegetation, as producers in the food chain, and as one of the pioneer plants in the succession of forest ecosystems. This study aims to determine the species, diversity index, and distribution pattern of ferns based on different vegetation in the Forest Area of Bukum Village, Sibolangit District, North Sumatra. The method used in this research is an exploratory survey method with a purposive sampling technique. The results of this study were 39 species found in the Forest Area of Bukum Village, 21 species in the watershed vegetation, 16 species in the Coffee Garden vegetation, and 14 species in the Primary Forest vegetation. The diversity index in the watershed vegetation is 2.32, the coffee plantation is 2.02, and the primary forest is 1.86. Based on the results of the diversity index, it shows that the diversity of ferns in the Forest area of Bukum Village is classified as moderate so the community is said to be stable. The Morisita index on the river flow vegetation is 1.43, the coffee garden vegetation is 2.13, and the primary forest vegetation is 2.05. The results of the Morisita index from each vegetation indicate that the distribution pattern of ferns in the Forest Area of Bukum Village is grouped because the environmental conditions required by ferns are not uniform.

Abstract

This study investigates the diversity and composition of phytoplankton as a bioindicator of water quality in the mangrove ecosystems of Merdeka Beach, Bagan Kuala Village, Serdang Bedagai. Sampling was conducted at three sites representing long-term rehabilitation (2010–2025), recent rehabilitation (2024–2025), and mangrove ecotourism areas. Phytoplankton abundance and diversity were analyzed using ecological indices, including Shannon-Wiener Diversity Index (H’), Trophic Diatom Index (TDI), and Percentage Pollution Tolerance Value (%PTV), alongside physicochemical water parameters. Results indicate spatial variation in water quality and phytoplankton communities. Station 1 showed moderate abundance and high diversity, indicating ecological stability. Station 2 exhibited increased abundance but lower diversity, reflecting transitional conditions. Station 3 demonstrated the highest abundance and pollution-tolerant taxa, consistent with elevated nutrient levels due to human activities. TDI and %PTV values corroborated these findings, identifying Station 3 as hypertrophic and heavily polluted. These results highlight the utility of phytoplankton as sensitive indicators of environmental quality and the effectiveness of rehabilitation efforts. The integration of biotic indices and water parameters provides a robust framework for ongoing ecological monitoring and coastal management strategies, particularly in mangrove ecosystems undergoing anthropogenic pressure and restoration.

Abstract

Butterflies belong to the order Lepidoptera which has essential roles such as pollinating insects (pollinators), evaluating environmental quality, and indicators of habitat change. The research aims to determine the types of butterflies, diversity, relative abundance, and dominance index in the Sibayak II Forest area of North Sumatra. This research is a quantitative descriptive research by combining the cruising method and the VES method. Sampling was carried out at three altitudes 1300-1500 masl, 1500-1700 masl, and 1700-1900 masl using insect nets. The results obtained were 31 species of butterflies from 6 families, with the highest number of individuals from three heights, namely Mycalesispatiana in Sibayak II Forest, North Sumatra. The index value of butterfly species diversity in Sibayak  II Forest with an average value of 2.67 is included in the medium category. The relative abundance index value of the most abundant butterfly species is the Mycalesis patiana with a discount of 34%. The overall butterfly dominance index value is 0.124. Based on the species diversity index, relative abundance and dominance index indicate environmental conditions in accordance with the life cycle and food sources as well as the distribution of host plants in Sibayak  II Forest.

Abstract

Kandungan karbon tersimpan terdapat pada permukaan tanah sebagai biomassa tumbuhan, sisa tumbuhan yang sudah mati (nekromasa), maupun dalam tanah sebagai bahan organik tanah. Tulisan ini memaparkan tentang  bagaimana kandungan karbon tersimpan pada hutan primer dan hutan sekunder. Cadangan karbon pada berbagai kelas penutupan lahan di hutan alam berkisar antara 7,5 – 264,70 ton C/ha. Pada hutan primer cadangan karbon berkisar 15,02 – 264,70 ton C/ha. Cadangan karbon terendah terdapat pada hutan bukit kapur dan tertinggi pada hutan alam primer dataran rendah dan dipterokarpa. Hutan alam sekunder  memiliki cadangan karbon berkisar 7,5 – 249,1 ton C/ha, dengan cadangan karbon terendah pada hutan bekas bakaran dan tertinggi pada hutan bekas tebangan. Cadangan karbon hutan alam primer lebih tinggi dari pada hutan alam sekunder yang disebabkan oleh keanekaragaman jenis tumbuhan pada hutan alam primer lebih tinggi dibandingkan dengan hutan sekunder sehingga pengembalian karbon organik ke dalam tanah berjalan dengan cepat dan penyimpanan biomassa hasil konversi karbon bertambah besar seiring dengan semakin banyaknya karbon yang diserap pohon tersebut.

Abstract

This study aims to assess the diversity index, relative abundance, and evenness of soil insects in the Hutan Desa Serdang, Tahura Area, Karo District, North Sumatra. The methods used include pitfall traps and bait traps with a purposive sampling approach at three observation stations: primary forest, secondary forest, and pine forest. The results show that a total of 1,427 insect individuals were found, comprising 8 orders, 13 families, and 20 species. Odontomachus brunneus exhibited high relative abundance, followed by Entomobrya handschini and Solenopsis invicta, which fall into the category of moderate relative abundance. The diversity index of soil insects is categorized as moderate, with an value of H' = 2.0, indicating a balanced ecosystem with a sufficient variety of species. Meanwhile, the evenness index of soil insects is classified as high, with a value of H'= 0.7. This indicates a uniform distribution of species without particular dominance, thus supporting ecological balance and good soil ecosystem quality.
