Abstract

Masifnya pembangunan perkotaan menyebabkan pemenuhan RTH terabaikan, hal ini membutuhkan keterlibatan seluruh pihak salah satunya adalah PT Kaltim Methanol Industri sebagai salah satu perusahaan di Kota Bontang juga berupaya pemenuhan RTH di Kota Bontang bisa dipenuhi salah satunya adalah dengan mengelola RTH secara mandiri, PT KMI mengelola taman metanol sebagai salah satu RTH yang berlokasi di Bontang Lestari. Penelitian ini bertujuan mengetahui serapan karbon dan keanekaragaman jenis vegetasi. Penelitian ini dilakukan pada bulan April hingga Mei 2023 menggunakan sistematik sampling dengan 22 plot yang merupakan 17,8% area lokasi. Pengambilan sampel dengan plot kuadrat 20 m x 20 m. Biomaasa pada taman metanol sebesar 377,98 ton/Ha, dengan kandungan karbon total sebesar 173,87 ton/Ha. Sehingga taman metanol memili kemampuan serapan karbon saat ini sebesar 637,58 ton/Ha. Terdapat 39 jenis dari 14 famili yang menjadi penyusun vegetasinya. Keanekaragaman di Taman Methanol tergolong ke dalam kategori sedang dengan tingkat kemerataan yang tinggi dan nilai dominansi yang rendah.

Abstract

East Kalimantan represents the lowland rainforest ecosystem with a vast number of macrofungi species in Indonesia. This study aimed to evaluate the diversity of macrofungi within the two different locations in East Kalimantan. The study was conducted in several phases, including planning, survey, preparation, sampling, and data analysis. Sampling was carried out systematically in 20 20 m plots. Collected samples were processed, photographed, and identified. Ecological indices, including the Shannon-Wiener diversity index, species evenness, and the Simpson dominance index, were calculated to provide a detailed analysis of the macrofungal community structure. This study found that location 1 recorded 24 species from 21 genera, while location 2 had 22 species from 20 genera. The Shannon-Wiener diversity index indicated moderate diversity at both sites, with values of 2.82 for location 1 and 2.65 for location 2. Daedaleopsis confragosa was the most frequent and dominant species in location 1, contributing 12.03% relative density, while Marasmiellus candidus dominated location 2 with 18.51% relative density. Species evenness was medium in both locations, and the dominance index was low, highlighting the ecological significance of these fungal species in their respective habitats. The results emphasize the importance of studying fungal ecology to support conservation and sustainable environmental management. The study revealed a wide variety of macrofungi that play vital roles in the tropical ecosystems of these two locations in East Kalimantan.
