Abstract

This study aims to assess the diversity of butterflies (Lepidoptera: Rhopalocera) at the location of the PT Pertamina Geothermal Energy (PGE) Lumut Balai Geothermal powerplant, Muara Enim, South Sumatra. This rapid survey was carried out on 4-15 June 2023, taking place in 7 locations namely Cluster 5, Cluster 6, Cluster 7, Cluster 9, Cluster 10, APL 17 and APL 18. The method used is the direct observation method by walking along a 1000 meter transect line (Yustian et al., 2017) in each type of habitat (secondary forest, mixed shrub secondary forest, coffee plantation , open areas and secondary forests near to rivers/water sources). The results obtained in this rapid survey are that there are 5 butterfly families consisting of Papilionidae, Pieridae, Nymphalidae, Hesperiidae and Lycaenidae with a total of 51 species and 254 individuals. The highest diversity index based on Shannon's diversity index and Margaleff's species richness index is in APL 17 with a secondary forest habitat type near to coffee plantations (H'=3.14, R=7.08) and the lowest is in Cluster 9 (H'=2.11, R=3.23) which is a secondary forest near to a geothermal power plant. Meanwhile, the highest evenness index was found in APL 17 (E=0.97) and the lowest in Cluster 7 (E=0.87) with a riparian habitat type. During the research, protected species were recorded, namely Troidesamphrysus and Troideshelena.

地热发电厂地区的蝴蝶多样性：南苏门答腊省穆拉埃尼姆市 Pt.

本研究旨在评估南苏门答腊省 Muara Enim 的 PT Pertamina 地热能源公司 (PGE) Lumut Balai 地热发电厂所在地的蝴蝶（鳞翅目：Rhopalocera）多样性。本次快速调查于 2023 年 6 月 4 日至 15 日进行，共涉及 7 个地点，即第 5 组、第 6 组、第 7 组、第 9 组、第 10 组、APL 17 和 APL 18。采用的方法是直接观察法，即在每种栖息地类型（次生林、混合灌木次生林、咖啡种植园、开阔地和靠近河流/水源的次生林）中沿 1000 米横断线行走（Yustian 等人，2017 年）。本次快速调查的结果显示，共有 5 个蝴蝶科，包括凤蝶科（Papilionidae）、蝶科（Pieridae）、蛱蝶科（Nymphalidae）、蝶属（Hesperiidae）和蝶属（Lycaenidae），共计 51 个物种和 254 个个体。根据香农多样性指数和 Margaleff 物种丰富度指数，APL 17 的多样性指数最高（H'=3.14，R=7.08），属于次生林生境类型，靠近咖啡种植园；第 9 组的多样性指数最低（H'=2.11，R=3.23），属于次生林生境类型，靠近地热发电厂。同时，均匀度指数最高的是 APL 17（E=0.97），最低的是第 7 组（E=0.87），属于河岸生境类型。在研究过程中，记录到了一些受保护物种，即 Troidesamphrysus 和 Troideshelena。
