    Abstract
    The use of liquid waste from palm oil mill, PT. Cipta Agro Sejati, to the community-owned oil palm plantation area which was distributed by land application system, will affect the physico-chemical soil which in turn affects the presence of soil insects that live and are active in the soil. This study aims to analyze the community composition and species of soil macrofauna insects that act as bioindicators in the community-owned oil palm plantation area which has been fed with liquid waste from the palm oil mill of PT. Cipta Agro Sejati, in Ampean Rattan Hamlet, District of Parit City, Simpang Kanan District, Rokan Hilir Regency, Riau Province. The study was carried out in July 2021. Determination of the sampling plot locations was done using Purposive Sampling method. Meanwhile, sampling of soil macrofauna insects was carried out using the Quadratic and Hand Sorting methods. From this study, it was found that in insects class the highest number of species was found in Block III, which was 13 species, followed by Block I with 10 species, and the least was in Block II with 8 species. The highest total density value in block III was 2944.5. Coptotermes curvignathus showed the highest frequency of presence with the value of 33.33%. The first order in the composition of soil macrofauna insects with a KR value of 71.72% was Macrotermes gilvus. Odontoponera tranversa and Oecophylla longinoda were found as bioindicators of soil macrofauna insect.
     
    Adanya pemanfatan limbah cair pabrik kelapa sawit PT. Cipta Agro Sejati ke areal kebun kelapa sawit milik masyarakat yang dialirkan dengan system aplikasi lahan (Sistem Land Application), keadaan ini akan berpengaruh terhadap fisik-kimia tanah yang akan mempengaruhi keberadaan insekta tanah yang hidup dan aktif di dalam tanah. Penelitian ini bertujuan menganalisis komposisi komunitas dan spesies insekta tanah yang berperan sebagai bioindikator pada areal perkebunan kelapa sawit milik masyarakat yang dialiri dengan limbah cair pabrik kelapa sawit PT. Cipta Agro Sejati, di Dusun Ampean Rotan, Kepenghuluan Kota Parit, Kecamatan Simpang Kanan, Kabupaten Rokan Hilir, Provinsi Riau. Penelitian Dilaksanakan pada bulan Juli 2021. Penentuan lokasi plot sampling dilakukan dengan metode Purposive Sampling. Sedangkan pengambilan sampel makrofauna insekta tanah dilakukan dengan metode Kuadrat dan Hand Sorting. Dari Penelitian ini didapatkan kelas insekta dengan jumlah spesies yang paling banyak didapatkan pada Blok III, yaitu sebanyak 13 spesies, kemudian diikuti oleh Blok I sebanyak 10 spesies, dan yang paling sedikit pada Blok II sebanyak 8 spesies. Nilai kepadatan total tertingggi pada blok III sebesar 2944,5. Frekuensi kehadiran (FK) yang tertinggi dijumpai pada spesies Coptotermes curvignathus dengan nilai 33,33%. Urutan komposisi makrofauna insekta tanah yang pertama dengan nilai KR 71,72% adalah Macrotermes gilvus. Spesies makrofauna insekta tanah sebagai bioindikator adalah Odontoponera tranversa dan Oecophylla longinoda.
