Abstract

Rice is one of the various types of food plants that are predominantly cultivated as a staple food for the Indonesian people. The importance of rice plants in cultivation cannot be underestimated, considering that more than half of Indonesia's population depends on this plant as a staple food. The problem is, each rice cultivation activity is closely related to the role of arthropods, both positive and negative roles. This study was conducted in conventional and organic rice fields in Brenjonk village with an altitude of 800 meters above sea level with an area of ​​600m² slowly. The research method applied during the study was the survey method or exploration method through plant selection with purposive sampling. Research parameters were obtained through direct observation of arthropods, pitfall traps, yellow sticky traps, sweep nets, and light traps. Insect identification was carried out using literature studies with naturalist applications and insect introduction books. The results of the observations showed that arthropods were found to act as pests, predators, parasitoids, pollinators and decomposers with a diversity index (H') of insects on land A (conventional) of 0.332 and land B (organic) of 0.358, the category is classified as low diversity.

Abstract

Seledri (Apium graveolens L.) merupakan tanaman rempah penting yang dibudidayakan di dataran tinggi. Salah satu penyakit yang dapat menurunkan produksi tanaman seledri adalah puru akar yang disebabkan oleh nematode parasit Meloidogyne sp. Pengendalian nematoda sampai dengan saat ini menggunakan pestisida yang toksik, sulit terdegradasi, dan berdampak negatif terhadap lingkungan. Upaya pengendalian biologis saat ini banyak dikembangkan, salah satunya penggunaan mikroorganisme bakteri endofit. Tujuan penelitian: mengetahui potensi bakteri endofit asal lahan basah Kalimantan Selatan sebagai agensia hayati nematode puru akar Meloidogyne sp pada tanaman seledri. Penelitian dilaksanakan dua tahap yaitu : eksplorasi bakteri endofit di lahan basah Kalimantan Selatan Bulan November 2021 dan uji vitro dilaksanakan di Laboratorium Kesehatan Tanaman Fakultas Pertanian Universitas Pembangunan Nasional “Veteran” Jawa Timur Bulan Desember 2021 menggunakan Rancangan Acak Lengkap. Uji dilakukan dengan cara 1 ml suspensi nematoda berisi ± 50 ekor juvenile 2 nematoda hasil ekstraksi dituang dalam 5 ml suspensi bakteri endofit berumur 48 jam yang dipanen menggunakan media NB dan diuji keamanan hayatinya dengan kode isolate BLR 1.2, BLR 1.3, BLR 2.1, BLR 2.2, BLR 2.3, BLR 3.2, AKL 2.1, AKL 2.2, AKL 3.1. Isolate kode BLR 2.2, BLR 1.3 ,BLR 3.2, BLR 2.1 merupakan isolate dengan jumlah mortalitas tertinggi dengan jumlah 50.67%, 45.33%, 49.33% dan 45.33% pada 12 jam setelah perlakuan
