“…Cacing tanah yang ditemukan di lokasi penelitian terdiri dari tiga jenis yaitu Pontoscolex, Microscolex, dan Pheretima. Pontoscolex memiliki panjang tubuh berkisar antara 45-120 mm, diameter 2-3 mm, jumlah ruas berkisar antara 120-167 (Jayanthi et al, 2014). Genus ini berwarna keputih-putihan dan agak kecoklatan, belum pada ruas 15/16-21/23, kelongsong dinding pada punggung menebal, ruas-ruas masih terlihat jelas, dan warnanya kekuningan, lubanglubangnya sensitif seperti tiga pasang dan terletak di 6 / 7-8/9, alat kelamin laki-laki pada 20/21 septa atau di belakang daerah klitoris (Suin, 2003).…”

Kegiatan pemanenan kayu umumnya menggunakan alat-alat berat yang berdampak pada aspek ekologi dimana terjadi kerusakan pada tanah. Tujuan dari penelitian ini adalah mengetahui dampak pemanenan hutan terhadap sifat biologi tanah dan kandungan karbon di BKPH Sengguruh KPH Malang. Pengambilan contoh tanah dilakukan secara acak, pengambilan contoh cacing secara acak dengan metode hand sorting dan untuk isolasi jamur dan bakteri dengan menggunakan agar cawan. Dari penelitian yang dilakukan diketahui terjadi penurunan kandungan bahan organik tanah pada lahan setalah pemanenan dari kelas agak tinggi menjadi rendah, ditemukan tiga jenis cacing yaitu Pheretima, Pontoscolex, dan Microscolex yang mengalami penurunan kepadatan individu pada pasca pemanenan dari 39,54 individu/m² menjadi 16,87 individu/m2. Jumlah koloni jamur dan bakteri pasca pemanenan mengalami penurunan pada koloni jamur dari 2,54 x 104 CFU/ml menjadi 0,88 x 104 CFU/ml dan pada koloni bakteri dari 22,58 x 105 CFU/ml menjadi 17,6 x 105 CFU/ml. Hasil perhitungan estimasi karbon ini diharapkan dapat berfungsi sebagai dasar untuk menghitung estimasi karbon dalam Vegetasi Hutan Jati dalam Skala Nasional.

“…On the contrary, according to Brata [14], earthworms are rare in soils with a pH below 4, since the optimum acidity (pH) for earthworms is 6,8-7,2. According to Jayanthi [15], to maintain the water content in the body of earthworms, soil moisture is needed for the respiratory process. Whereas according to Febrita [8], good humidity for earthworms is between 15%-50%.…”

The research objective was to find out the potential of earthworms (Lumbricus sp.) in residential environments, rice fields, and cattle farms in Anrelli Village, Kulo District as an environment-based biology learning resource. The research used a descriptive study with a descriptive-qualitative research method. The research population was all Lumbricus sp., in Anrelli Village, Kulo District. The research samples were all Lumbricus sp., from three locations with an area of 1 x 1 m and a depth of 0-30 cm. The supporting samples of the study were the physical, chemical, and biological soil conditions. The sampling techniques used purposive sampling with Hand-Sorting method. The data analysis technique is descriptive-qualitative with an inductive approach on the subject of Animal World in 10 th grade according to KI.3 and KD. 3.3. The supporting sample used the Morario formula. The research results were Lumbricus terrestris, Lumbricus castaneus, and Lumbricus rubellus. The earthworms morphologies that can be observed by students as learning resources are body size, skin/body surface, body-color, segments, setae, clitelium, and prostomium. These findings can be integrated as an environment-based biology learning resource by explaining the classification principles of living things in five kingdoms.

“…Pheretima sp. can survive and reproduce with relatively wide environmental conditions and locations (Jayanthi 2014), as geophagus species (live on the surface of the ground), able to live in low pH and organic matter, such as ultisols (Anwar 2009). According to Yusnaini et al (2008), the Pheretima sp.…”

The abundance and biomass of earthworms are affected by soil tillage and fertilization. This research aimed to study long-term 32nd-year soil tillage and nitrogen fertilization on the population and biomass of earthworms under Zea mays L. The research was conducted using a randomized block design (RBD) which consisted of two factors. The first factor was the soil tillage that was Intensive Tillage (IT), Minimum Tillage (MT), and No-Tillage (NT). The Second factor was nitrogen fertilization that was N0 = 0 kg N ha-1 and N1= 200 kg N ha-1. Data of earthworm population and biomass were tested using analysis of variance and continued with the least significant difference (LSD) test at the 95% significant level. The population and biomass of earthworms at MT or NT were higher than IT. The population and biomass of earthworms in the plots without fertilization were higher than those at 200 kg N ha-1. There was an interaction between the soil tillage and N fertilization on earthworm biomass observed 60 days after planting at a 0-10 cm depth. There was a positive correlation between soil pH and earthworm population and biomass before the tillage phase.
