Keanekaragaman Capung (Odonata) Di Tepi Sungai Kali Desa Kali Kabupaten Minahasa Sulawesi Utara

Abstract

Capung merupakan komponen keanekaragaman hayati yang memiliki peran sebagai bioindikator pencemaran lingkungan. Penelitian ini bertujuan untuk mengidentifikasi spesies dan menganalisis keanekaragaman capung di Sungai Kali Desa Kali, Kabupaten Minahasa, Sulawesi Utara. Pengambilan sampel dilakukan dengan mengunakan metode purposive random sampiling. Penelitian ini dilaksanakan pada tepi sungai kali yang terletak pada tiga tipe habitat yaitu di tepi sungai hutan sekunder, tepi sungai perkebunan dan tepi sungai permukiman. Masing-masing habitat dibuat tiga garis transek dengan panjang 300 Meter. Komposisi capung yang diperoleh terdiri dari 6 famili, 19 spesies dan 1.785 individu. Famili yang paling banyak ditemukan jumlah spesiesnya adalah Libellulidae. Spesies yang memiliki kelimpahan yang tertinggi Neurothemis ramburii dan Ortetrum pruinosum. Indeks kekayaan spesies di Sungai Desa Kali di kategorikan rendah, indeks keanekargaman di kategorikan sedang dan indeks kemerataan spesies tergolong dalam ketegori tinggiDragonfly is a biodiversity component that has a role as a bioindicator of environmental pollution. This study aims to identify species and analyze the diversity of dragonflies in Kali River Kali Village, Minahasa Regency, North Sulawesi. Sampling is done by using purposive random sampling method. This research was carried out on the river banks which are located in three habitat types, namely on the banks of secondary forest rivers, plantation banks, and residential riverbanks. Three transect lines were made on each habitat with a length of 300 meters. The dragonfly composition obtained consisted of 6 families, 19 species and 1,785 individuals. Most of the species are from family Libellulidae. Species with the highest abundance are Neurothemis ramburii and Ortetrum pruinosum. The species richness index in the Kali River River was categorized as low, the economic index was categorized as moderate, and the species evenness index was classified as high

Keanekaragaman Jenis Capung Di Lanskap Pertanian Goalpara-Perbawati Kabupaten Sukabumi Provinsi Jawa Barat

“…Nilai H' yang diperoleh di lokasi penelitian relatif tidak berbeda jauh jika dibandingkan dengan berbagai penelitain lain seperti Ilhamdi et al (2020), Lino et al (2019) maupun Zaman et al (2018). Nilai H' yang tinggi didukung oleh kualitas habitat yang baik sehingga mendukung tingginya keanekaragaman jenis capung yang dijumpai (Amrullah, 2018), sebaliknya bahwa nilai H' yang rendah mengindikasikan bahwa lingkungan kurang baik (Suaskara & Joni, 2020) seperti kualitas air yang rendah maupun penurunan debit air.…”

Community Structure of Dragonflies (Odonata) at Garahan Resort, Sempolan, Perhutani, Forest Management Unit (KPH) Jember

“…The utilization of dragonfly nymphs as water indicators are attributed to their inability to thrive in polluted water environments [9]. Furthermore, dragonflies have a crucial function as pest control agents, specifically as predators and natural adversaries of noxious organisms [10].…”

“…These encompass a range of geographical features, including lowland and highland regions, coastal areas, swamps, rivers, lakes, and ponds. Dragonflies are typically observed near bodies of water [10]. Furthermore, dragonflies can also be observed in forested regions.…”

Diversity and Abundance of Dragonfly (Anisoptera) and Damselfly (Zygoptera) at Sabo Dam Complang, Kediri, East Java, Indonesia

“…The diversity and abundance of dragonflies (including damselflies) (Lino, Koneri, and Butarbutar 2019) have an important role in the ecosystem in maintaining the balance of the food chain (Riyaz 2021). Dragonflies are flying insects that are predators of many small insects (Bell and Hitchomb 1961), including mosquitoes (Syarifah, Narti, and Fahma 2018) and flies (Safrudin and Maulana 2020).…”

“…Dragonflies can be regarded as predators (Kumar and Hwang 2006) because of their role in the food chain, which eradicates pest populations (Kandibane, Raguraman, and Ganapathy 2005;Purba and Yulminarti 2018). Dragonflies can also be used as environmental bioindicators (Lino, Koneri, and Butarbutar 2019) because their presence in the waters can indirectly indicate clean water (Husnia 2019).…”
