Abstract

Budidaya kopi Liberika pada umumnya dibudidayakan di bawah naungan. Namun di beberapa daerah, budidaya kopi Liberika menggunakan sistem tanpa naungan. Perbedaan intensitas naungan akan berpengaruh terhadap iklim mikro dan keberagaman komponen organisme dan mikroorganisme termasuk keberagaman serangga. Tujuan penelitian ini adalah mengetahui perbedaan keanekaragaman serangga pada 3 intensitas naungan. Berdasarkan hasil penelitian yang dilakukan di Kebun Percobaan Wirolegi, Jember, Jawa Timur pada bulan September hingga Oktober 2022 didapatkan hasil bahwa indeks keragaman serangga pada intensitas naungan 2:1 tergolong sedang dengan nilai 1.9, sedangkan untuk intensitas naungan 1:1 dan perlakuan tanpa naungan tergolong rendah dengan nilai 1.4. Ordo serangga yang dapat dijumpai pada naungan 2:1 adalah Arachnida, Coleoptera, Diptera, Hymenoptera, dan Orthoptera dengan 10 famili serangga. Sedangkan ordo serangga yang banyak dijumpai pada naungan 1:1 dan tanpa naungan adalah Arachnida, Coleoptera, Diptera, Lepidoptera, dan Orthoptera dengan masing-masing 9 famili dan 7 famili serangga.

Abstract

Meloidogyne spp. is a root-knot nematode that can cause damage to plants up to 68%. The common control is the use of pesticides, but in the long term, it can damage the soil, so it is necessary to use biological agents that can control Meloidogyne spp. without causing environmental damage. The purpose of this study was to determine the ability of endophytic bacteria to control root-knot nematodes Meloidogyne spp.. The method used in this study was the exploration of endophytic bacteria from the Wonorejo mangrove ecotourism area, Surabaya using purposive sampling method. The five best endophytic bacteria were tested further with antagonistic tests. This test was carried out in vitro using 3 concentrations, namely 106, 108, and 1010 CFU/ml with 3 repetitions. The obtained results were tested using probit analysis to obtain the LC50 values. It was found that LC50 values for the most effective concentration to kill 50% of the Meloidogyne sp population is 109 and 1010 CFU/ml. It was also revealed that the isolate that is most capable of controlling Meloidogyne spp. nematodes is isolate A43. Keywords: Antagonist test, Endhopic bacteria, LC50, Mangrove, Meloidogyne spp.
