Insekta permukaan tanah merupakan organisme berperan penting sebagai bioindikator kualitas habitat. Penelitian bertujuan untuk mengetahui tingkat kesamaan, keanekaragaman, dan menghasilkan produk buku identifikasi insekta permukaan tanah pada beberapa tipe habitat di Kecamatan Lembah Sabil Kabupaten Aceh Barat Daya. Penelitian menggunakan metode survey eksplorative dan teknik purposive sampling. Subjek penelitian ini adalah seluruh insekta permukaan tanah pada berbagai habitat di Kabupaten Aceh Barat Daya, dan objek penelitian adalah insekta permukaan tanah pada 4 titik pengamatan di Kecamatan Lembah Sabil Kabupaten Aceh Barat Daya. Data penelitian dianalisis secara kuantitatif dan kualitiatif. Hasil penelitian diperoleh tingkat kesamaan insekta permukaan tanah pada kebun kopi dengan hutan sekunder 0,59, hutan pantai dengan kebun pala 0,29, hutan pantai dengan kebun kopi 0,36, hutan pantai dengan hutan sekunder 0,29, kebun kopi dengan kebun pala 0,42, dan kebun pala dengan hutan sekunder 0,48. Tingkat keanekaragaman insekta permukaan tanah dengan kriteria sedang yaitu pada hutan pantai (2,693), kebun kopi (2,538), kebun pala (2,253), dan hutan sekunder (2,431). Hasil uji kelayakan terhadap produk hasil penelitian yaitu 76% layak digunakan. Simpulan penelitian bahwa tingkat kesamaan insekta permukaan tanah di Kecamatan Lembah Sabil Kabupaten Aceh Barat Daya pada kebun kopi dan hutan sekunder dengan kriteria tinggi, sedangkan hutan pantai, kebun pala, dan hutan sekunder memiliki tingkat kesamaan yang rendah. Tingkat keanekaragaman insekta permukaan tanah pada empat tipe habitat dengan kriteria sedang.

Ground-dwelling insects organisms that play an important role as bioindicators of habitat quality. This study aimed to determine the similarity and diversity levels of soil-surface insects, as well as to produce an identification book across several habitat types in Lembah Sabil, Aceh Barat Daya. The research was conducted using an explorative survey method with purposive sampling. The subjects of this study were all soil-surface insects found in various habitats in Aceh Barat Daya, while the objects were insects collected from four observation sites in Lembah Sabil. Data were analyzed both quantitatively and qualitatively. The results showed that the similarity index of soil-surface insects was 0,59 between coffee plantation and secondary forest, 0,29 between coastal forest and nutmeg plantation, 0,36 between coastal forest and coffee plantation, 0,29 between coastal forests and secondary forests, 0,42 between coffee and nutmeg plantation, and 0,48 between nutmeg plantation and secondary forest. The diversity index of soil-surface insects was categorized as moderate, namely coastal forest (2.693), coffee plantation (2.538), nutmeg plantation (2.253), and secondary forest (2.431). The feasibility test of the research product showed a score of 76%, categorized as feasible. In conclusion, the similarity of soil-surface insects in Lembah Sabil Subdistrict was relatively high between coffee plantation and secondary forest, while coastal forest, nutmeg plantation, and secondary forest showed low similarity. Meanwhile, the diversity of soil-surface insects across the four habitat types was classified as moderate.
