Abstract

Penelitian dilaksanakan di kebun kopi rakyat di Kecamatan Purba Kabupaten Simalungun (± 1.100 m dpl),  pada 4 jenis tingkat umur kopi yang berbeda. Waktu pelaksanaan penelitian bulan Februari - April 2019. Tujuan penelitian adalah untuk mengetahui intensitas serangan hama Hypothenemus hampei Ferr pada berbagai tingkat umur tanaman sebelum dan sesudah pemasangan atraktan serta untuk mengetahui jenis antraktan yang efektif untuk pengendalian Hypothenemus hampei Ferr. Penelitian menggunakan rancangan acak kelompok. Faktor yang diteliti yaitu intensitas serangan hama penggerek buah kopi pada lahan pertanaman umur 3, 5, 7, dan 9 tahun dan pengujian 3 jenis senyawa atraktan sintesis merek dagang yaitu Hypotan 500 SL, Koptan dan Antrakop 500 L untuk memerangkap serangga penggerek buah kopi. Parameter pengamatan yaitu intensitas serangan penggerek buah kopi sebelum pemasangan atraktan, jumlah penggerek buah kopi yang terperangkap atraktan, jenis serangga lain yang terperangkap selain Hypothenemus hampei Ferr, dan intensitas serangan penggerek buah kopi setelah pemasangan atraktan. Hasil penelitian, bahwa penggunaan atraktan sebagai perangkap hama pada pertanaman kopi umur 5 tahun, 7 tahun, dan 9 tahun mampu menurunkan intensitas serangan Hypothenemus hampei Ferr dari kategori intensitas serangan sedang menjadi kategori intensitas serangan ringan. Efektifitas jenis atraktan yang digunakan relatif tidak berbeda untuk memerangkap hama Hypothenemus hampei Ferr.

Abstract

Salah satu jenis penyakit yang sering menyerang tanaman jagung adalah penyakit hawar daun yang disebabkan patogen jamur Helmithosporium sp. Untuk mengendalikan penyakit, petani cenderung mengandalkan pestisida sintetis yang bisa menyeb abkan resistensi hama dan penyakit, menimbulkan pencemaran lingkungan, bahkan merugikan kesehatan manusia. Untuk mencegah dampak negatif pestisida sintesis perlu alternatif lain, misalnya dengan memanfaatkan agen hayati. Dewasa ini telah berhasil dikembangkan produk agen hayati yang diharapkan dapat menggantikan ketergantungan penggunaan pestisida sintesis. Pelaksanaan penelitian menggunakan rancangan acak lengkap, dilakukan di rumah kasa. Faktor yang diteliti ialah pemanfaatan agen hayati Tribac untuk mengendalikan penyakit hawar daun tanaman jagung, dengan menguji 4 tingkat konsentrasi berturut-turut 0,1%, 0,2%, 0,3% dan 0,4% dan 1 perlakuan pembanding tanpa pemberian agens hayati Tribac. Intensitas serangan hawar daun tanaman jagung dihitung menggunakan rumus : I = { ∑ (ni x vi) / (Z x N) } x 100%. Hasil penelitian menyimpulkan, agen hayati Tribac efektif mengendalikan penyakit hawar daun tanaman jagung yang disebabkan pathogen Helminthosporium sp. Tingkat konsentrasi aplikasi agen hayati Tribac 0,4% menghasilkan intensitas serangan yang terendah.

Abstract

In Simalungun Regency of North Sumatra, pest attacks of coffee fruit grinder Hypothenemus hampei Ferr are scattered throughout the coffee producing sub-district, with the intensity of moderate – heavy attacks. The widespread spread and high intensity of attacks, because generally farmers do not make control efforts by various limitations. Including technical culture practices, farmers do not all implement agronomical strategy that can prevent pest attacks. Field experimental was conducted on 2 types of coffee plantations with different of agronomical acts, using randomized design methods of series groups. Factors studied were the influence of protective trees and experiments tested 3 types of attracktant traps to control the attack of H. hampei Ferr. The research aimed to determine the incidence level of H. hampei Ferr pest attacks on protective tree-lined and treeless coffee plants and to determine the effectiveness of attracktan traps controlling coffee fruit grinding pests. To obtain the data, the experiment was made on both types of land. The calculated parameter were : (1). Intensity of attack of coffee fruit grinding pests before the installation of attracktant. (2). Number of coffee fruit grinders trapped attracktant, (3). Other types of insects trapped besides H.hampei Ferr, and (4). The intensity of coffee fruit grinding attacks after attracktant installation, was calculated using the formula: Is = {A/(A+B)} x 100% (Is = attack intensity, A = number of stricken seeds, and B = healthy number of seeds). Inferred, the intensity of attacks by coffee fruit-growing pests on coffee plantations with protective trees was lower than that of coffee plantations without protective trees. The use of attracktant traps on coffee plants with protective trees and without protective trees, is able to decrease the intensity of attacks from heavy category to medium. The effectiveness of 3 (three)attracktant types of Hypotan 500 SL, Atrakop 500 L and Koptan L to trap the pest H. hampei Ferr on a coffee field with protective trees and without protective trees was relatively no different.

Abstract

The purpose of this study was to determine the effectiveness of the herbicide dose level with the active ingredient glyphosate with the addition of 4 types of surfactants to control weeds in oil palm fields. The study used a separate plot design method with a randomized block trial pattern, testing the herbicide dose levels of 2, 3 and 4 liters of herbicide glyphosate/ha (as the main plot) and the addition of surfactant types (as subplots). The types of surfactants tested were Biosurfactant DEA, Biosurfactant DEA-3, Agristic (commercial surfactant) and Spreader (commercial surfactant) with a concentration of 0.5 ml/liter of herbicide solution. From the analysis of research data, it is known that the dose levels of 2, 3 and 4 liters per hectare of the herbicide glyphosate with the addition of 4 types of surfactants, did not show significantly different effectiveness in controlling weeds in oil palm plantation areas. The addition of DEA Biosurfactant, DEA-3 Biosurfactant, Agricultural Surfactant and Spreader Surfactant into the glyphosate herbicide solution did not significantly increase the effectiveness of the herbicide to control weeds in oil palm plantations. The herbicide glyphosate with the addition of 4 types of surfactants was effective in controlling Asystasia gangetica and Cyrtococcum oxyphillum weeds, but was not effective in suppressing the growth and development of Syngonium podophyllum and Adiantum latifolium weeds.
