Abstract
Penelitian ini bertujuan untuk menentukan diversitas cacing tanah di Malang Raya, karakter tanah habitat dan kadar protein cacing tanah lokal serta pertumbuhan tiga spesies cacing tanah lokal pada media kompos limbah tanaman pisang dan jerami padi. Tanah beserta cacing tanah diambil menggunakan metode handsorting dari kebun jagung di Kabupaten Malang, selokan dan taman di Universitas Brawijaya, serta bantaran Sungai Brantas. Tanah habitat diukur kadar N total, keasaman (pH), kelembaban, dan kadar protein cacing tanah. Selain itu, limbah pelepah dan kulit buah pisang serta jerami padi dicacah, difermentasi dengan isi rumen sapi selama dua minggu, selanjutnya media dianalisis kadar N total, keasaman (pH) dan kelembaban. Pengukuran jumlah dan berat individu tiap populasi cacing tanah dilakukan di awal dan akhir masa pertumbuhan. Hasil penelitian menunjukkan bahwa cacing tanah yang ditemukan adalah Pontoscolex sp., Amynthas sp., Pheretima sp. dan Perionyx sp. Cacing Pontoscolex sp. termasuk Famili Glossoscolecidae, sedangkan tiga spesies yang lain termasuk Famili Megascolecidae. Spesies cacing tanah tersebut dibedakan berdasarkan tipe seta, klitelum, serta responnya terhadap rangsang sentuhan. Kadar N total tanah habitat berkisar antara 0,13-0,25%. Keasaman tanah habitat bernilai 7 kecuali di kebun jagung (pH 4). Kelembaban tanah habitat tertinggi terdapat di bantaran Sungai Brantas sebesar 77%, sedangkan kelembaban tanah di lokasi lain berkisar antara 33-41%. Kadar protein tertinggi dimiliki Perionyx sp. sebesar 44,58%. Perionyx sp. mampu bertahan hidup pada media limbah pisang dan jerami padi sedangkan Pheretima sp. dan Amynthas sp. tidak mampu bertahan hidup.
English Abstract
The aimes of this research were to determine local earthworm diversity, soil habitat characters and protein content, and to grow three local earthworm species in media composed by waste compost. Earthworms were collected using handsorting methods in maize field in Malang, sediment of drainage and park in Brawijaya University campus, and Brantas riverside area. Soils habitat were characterized by measuring N total, alkalinity (pH) and humidity. Each earthworm species was measured for protein content. Banana (stem and fruit leather) and rice straw waste fermented during 2 weeks, then analyzed for N total, alkalinity (pH) and humidity. The number and individual biomass of each earthworm were determined at the up and harvesty The result showed that the earthworm found were Pontoscolex sp., Amynthas sp., Amynthas sp., Pheretima sp. and Perionyx sp. Pontoscolex sp. is member of Family Glossoscolecidae, and others are grouped in Family Megascolecidae. Those earthworms were identified based on type of setae, clitellum and their response to touch. The N total content of soil habitat was 0.13 to 0.25%. Alkalinity (pH) of soil habitat was 7 except in maize field (pH 4). The highest soil habitat moisture was in Brantas riverside area (77%), however in the other locations ranged 33 to 41%. The highest protein content was achieved by Perionyx sp. (44.58%). Among them, only Perionyx sp. could grow in composted banana and rice straw waste.
