Tarigan, Cindy Adriani and Dr.Agr.Sc.Hagus Tarno,, SP.,MP (2020) Efektivitas Beberapa Metode Pengambilan Sampel Nematoda Mononchus Pada Lahan Wortel (Daucus Carota L.) Di Desa Tulungrejo, Kecamatan Bumiaji. Sarjana thesis, Universitas Brawijaya.

Abstract

Tanaman wortel yang umbinya di dalam tanah rentan terkena serangan Organisme Pengganggu Tanaman (OPT). OPT yang biasanya menyerang umbi wotel yaitu nematoda. Tidak hanya sebagai OPT, ada beberapa nematoda yang bersifat non-parasit (free living) seperti mononchus. Nematoda nonparasit tanaman yang hidup bebas sangat penting dan bermanfaat dalam dekomposisi bahan organik dan daur ulang nutrisi dalam tanah. Mengetahui jumlah/populasi di dalam tanah dapat dilakukan dengan mengambil sampel tanah. Tujuan dari pengambilan sampel tanah yaitu mewakili data suatu lahan. Metode pengambilan sampel nematoda di dalam tanah dengan menggunakan beberapa metode seperti zig-zag,diagonal,acak purposive, m-shape dan damaged area. Pada umumnya, para peneliti mengaplikasikan metode pengambilan sampel acak purposive. Perlunya pengujian atau pengkajian kelima metode tersebut dengan tujuan menemukan kefektivitasannya untuk menghemat waktu pengerjaan (efesiensi) di lapangan (lahan) dan keakuratan (efektif) pengambilan data berupa populasi/jumlah obyek yang ingin diamati oleh peneliti nematoda. Pengambilan sampel tanah dilakukan di lahan petani tepatnya di Desa Tulungrejo, Kecamatan Bumiaji,Kabuapaten Malang. Jumlah lahan yang diamati sebanyak 4 lahan dengan pengulangan pada tiap lahan sebanyak 6 ulangan . Penelitian ini menggunakan sampel tanah 100gr dan 10 gr sampel akar pada setiap pengulangan dengan metode ekstraksi whiteheadtray. Hasil populasi nematoda mononchus yang didapatkan yaitu 193 ekor, metode diagonal jumlah nematoda ;264 ekor, metode acak purposive; 511 ekor, metode m-shape; 413 ekor dan metode damaged area; 395 ekor. Populasi keseluruhan nematoda yang diidentifikasi yaitu 1.741 ekor. Peneliti menyimpulkan bahwa dengan metode pengambilan sampel acak purposive efektif dan efesien dengan rata-rata populasi 85,16 ekor.

English Abstract

Carrot plants whose tubers are in the soil are susceptible to attack by Plant Pest Organisms (OPT). The pests that usually attack the wotel tubers are nematodes. Not only as a pest, there are some nematodes that are non-parasitic (free living) such as mononchus. Free-living plant non-parasitic nematodes are very important and beneficial in the decomposition of organic matter and recycling of nutrients in the soil. Knowing the amount / population in the soil can be done by taking soil samples. The purpose of taking soil samples is to represent land data. The sampling method for nematodes in the soil uses several methods such as zigzag, diagonal, random purposive, m-shape and damaged areas. In general, researchers apply a purposive random sampling method. It is necessary to test or study the five methods in order to find their effectiveness in order to save processing time (efficiency) in the field (land) and to accurately (effectively) collect data in the form of population / number of objects that the nematode researcher wants to observe. Soil sampling was carried out in farmers' land to be precise in Tulungrejo Village, Bumiaji District, Malang Regency. The number of land observed was 4 with 6 repetitions for each area. This study used a soil sample of 100 gr and 10 gr of root samples in each repetition using the whiteheadtray extraction method. The results obtained were 193 mononchus nematode populations, the diagonal method of the number of nematodes, 264 individuals, purposive random method; 511 tails, m-shape method; 413 tails and damaged area methods; 395 individuals. The total population of identified nematodes was 1,741. The researcher concluded that the purposive random sampling method was effective and efficient with a population mean of 85.16 individuals.
