The purpose of this study was to examine the effect of the type of color and light intensity of the light emitting diode (LED) Light traps on the type and number of insect pests in rice plantations. The research was conducted from November 2017 to March 2018, in Kencong Village, Jember Regency. The data collection method used Scan sampling, for 11 weeks, one week interval, starting at 07.00 p.m. to 04.00.a.m. The number of plots was 4 pieces, each 100 m2. The distance between the plots is 100 meters. Light traps in each plot, red, yellow, blue and white. Each color consists of 4 light intensities, namely 3 watts, 5 watts, 7 watts and 9 watts. Observation parameters: types and number of insect pests catches. The different types and numbers of insect pests caught were using the Kruskal-Wallis test. The normality of the data used the Shapiro-Wilt test. Statistical significance p < 0.05. Correlation between lamp color and light intensity, using the Spearman correlation test. Data were analyzed using SPSS version 23.0. The conclusions of the study were: The types of insect pests at various colors and intensity of LED light traps showed similarities, consisting of 5 orders, 6 families and 6 species. The red LED trap light indicates the highest number of pest catches. The number of insect pest catches of red LED was 475 individuals. A light intensity of 9 Watts indicates the highest number of insect pest catcheswere 568 individuals. The spearman correlation coefficient between the type of LED color and the light intensity (r) = -0.415.

Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan Trichoderma  spp. terhadap penyakit karat daun Phakopsora pachyrizi Syd pada tanaman kedelai Edamame. Penelitian ini dilakukan di Desa Dukuh Mencek, Kecamatan Sukorambi, Kabupaten Jember, dimulai Desember 2019  sampai Maret 2020. Metode penelitian ini membandingkan dua areal tanaman Edamame dengan perlakuan berbeda dalam pengendalian penyakit karat daun. Areal pertama menggunakan Trichoderma spp. konsentrasi 108 CFU dosis 500 liter per ha, pupuk kandang kotoran sapi, dosis 5 ton per ha, mulsa jerami 5 ton per ha. Biourine 1 liter dicampur 10 liter air dengan cara disemprotkan pada tanaman. Areal kedua menggunakan fungisida berbahan aktif Metalaksil konsentrasi 2 gram/liter, dosis 500 liter per ha, Urea 150 kg/ha, SP-36 150 kg/ha, KCl 100 kg/ha., pupuk daun Gandasil D. Peubah yang diamati: daya hambat Trichoderma spp tehadap pertumbuhan P.pachyrizi, intensitas serangan, jumlah dan berat polong per rumpun. Data dianalisis menggunakan perangkat lunak SPSS versi 23.0. Kesimpulan penelitian adalah: daya hambat Trichoderma spp terhadap P. a pachyrizi 106 CFU adalah 25%, 108 CFU adalah 50% dan 109 CFU adalah 75%, Intensitas serangan P. pachyrizi perlakuan fungisida Trichoderma spp adalah 0,70 persen, lebih rendah dibanding Metalaksil yaitu 1,17 persen. Jumlah polong perlakuan fungisida Trichoderma spp adalah 20,88 polong per rumpun, lebih rendah dibanding Metalaksil yaitu 29,76 polong per rumpun. Berat polong perlakuan fungisida Trichoderma spp adalah 41,66 gram per rumpun, lebih rendah dibanding Metalaksil yaitu 51,72 gram per rumpun.
