Abstrak. Hypothenemus hampei penggerek buah kopi merupakan hama penting pada tanaman kopi yang dapat menurunkan kualitas dan kuantitas biji kopi. PBKo dapat menyerang buah kopi mulai dari buah yang masih hijau sampai buah masak. Salah satu alternatif pengendalian hama PBKo adalah penggunaan ekstrak biji kopi sebagai atraktan. Tujuan dilakukan penelitian ini yaitu untuk mengetahui keefektifan ekstrak biji kopi sebagai atraktan untuk mengendalikan penggerek buah pada tanaman kopi arabika di Kabupaten Aceh Tengah. Penelitian ini telah dilaksanakan sejak bulan April sampai September 2021. Pemasangan perangkap dilakukan di Kecamatan Lut Tawar Kabupaten Aceh Tengah sedangkan identifikasi dilaksanakan di Laboratorium Hama Tumbuhan Program Studi Proteksi Tanaman, ekstraksi biji kopi dilaksanakan di Laboratorium Analisis Pangan Fakultas Pertanian Universitas Syiah Kuala. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor yang diteliti yaitu: (1) Konsentrasi ekstrak biji kopi yaitu, E0: 0%, E1: 20%, E2: 30%, dan E3: 40%, (2) Faktor ketinggian perangkap yaitu, T1: 75 cm, T2: 150 cm. Parameter yang diamati adalah jumlah imago betina H. hampei yang terperangkap, persentase buah yang terserang H. hampei serta serangga lain yang terperangkap. Berdasarkan hasil pengamatan jumlah imago H. hampei betina yang terperangkap, bahwa rerata pada perlakuan ekstrak biji kopi pada pengamatan minggu 1, 2, 4, 5 setelah pemasangan dilihat bahwa ekstrak biji kopi berpengaruh sangat nyata, tetapi berpengaruh tidak nyata pada pengamatan minggu ketiga. Jumlah H. hampei yang terperangkap dengan populasi tertinggi yaitu pada pengamatan pertama perlakuan ekstrak dengan konsentrasi 30% dengan rerata mencapai 1,759. Perangkap ekstrak biji kopi konsentrasi 30% lebih efektif mengendalikan hama H. hampei di Kecamatan Lut Tawar Kabupaten Aceh Tengah, dibandingkan dengan konsentrasi 20%, 40% dan pada perlakuan kontrol hama PBKo paling sedikit terperangkap.Kata kunci : Hypothenemus hampei, ekstrak Biji kopi, kopi Arabika. The effectiveness of coffee bean extract as an attractant to control fruit borer (Hypothenemus hampei Ferr.) on arabica coffee plants in Central Aceh Regency Abstract. The coffee berry borer Hypothenemus hampei is an important pest on coffee plants that can reduce the quality and quantity of coffee beans. H. hampei can attack coffee cherries ranging from green fruit to ripe fruit. One alternative for controlling H. hampei pests is the use of coffee bean extract as an attractant. The purpose of this study was to determine the effectiveness of coffee bean extract as an attractant for controlling fruit borer pests on Arabica coffee plants in Central Aceh District. This research was carried out from April to September 2021. The arrests were carried out in Lut Tawar District, Central Aceh Regency, while identification was carried out at the Plant Pest Laboratory of the Plant Protection Study Program, coffee bean extraction was carried out at the Food Analysis Laboratory, Faculty of Agriculture, Syiah Kuala University. This study used a factorial randomized block design (RAK) with 2 factors studied, namely: (1) The concentration of coffee bean extract, namely, E0: 0%, E1: 20%, E2: 30%, dan E3: 40%, (2) The trap height factor is, T1: 75 cm, T2: 150 cm. The parameters observed were the number of trapped female H. hampei imago, the percentage of fruit attacked by H. hampei, and other trapped insects. Based on the results of observations of the number of trapped female H. hampei imago, that the average coffee bean extract treatment at weeks 1, 2, 4, 5 observations after installation was seen that coffee bean extract had a very significant effect, but had no significant effect on the third week observation, Total H. Hampei trapped with the highest population, namely in the first observation of extract treatment with a concentration of 30% with an average of 1.759. The 30% concentration of coffee bean extract traps was more effective in controlling H. hampei pests in Lut Tawar District, Central Aceh Regency, compared to concentrations of 20%, 40% and the H. hampei pest control treatment was the least trapped.Keywords: The coffee berry borer, coffee bean extract, arabica coffee.
Abstrak. Salah satu alternatif yang dapat digunakan dalam budidaya tanaman sebagai mikrohabitat yang dapat menjadi tempat berlindung yang nyaman bagi musuh alami, menyediakan sumber pakan berupa nektar dan mendukung komponen interaksi biotik dalam suatu ekosistem, seperti polinator (serangga penyerbuk) adalah tanaman refugia. Tujuan dari penelitian ini adalah untuk mengetahui kehadiran serangga parasitoid pada pertanaman cabai merah dengan tanaman refugia. Penelitian ini menggunakan metode deskriptif kuantitatif. Tanaman yang dibudidayakan dalam penelitian ini antara lain cabai merah varietas LABA F1, tanaman refugia yaitu Tagetes erecta L., Zinnia elegans dan Cosmos caudatus. Hasil Penelitian ditemukan jumlah individu serangga pada sistem budidaya tanaman cabai merah dengan tanaman refugia adalah 3.618 individu yang tergolong dalam 8 ordo dan 29 famili. Ordo serangga dengan komposisi 41,95% merupakan komposisi tertinggi yang ditemukan berasosiasi pada pertanaman cabai merah dengan tanaman refugia yaitu Ordo Hymenoptera yang juga merupakan ordo dari serangga- serangga parasitoid yang ditemukan pada lahan penelitian.Abstract. One alternative that can be used in plant cultivation as a microhabitat that can be a comfortable shelter for natural enemies, provides a source of food in the form of nectar and support components of biotic interactions in an ecosystem, such as pollinators (pollinating insects), is the refugia plant. The purpose of this study was to determine the presence of parasitoid insects on red chili plants with refugia plants. This study uses a quantitative descriptive method. The plants cultivated in this study include red chilies of the LABA F1 variety, refugia plants, namely Tagetes erecta L., Zinnia elegans and Cosmos caudatus. The results of the study the number of individual insects in the red chili cultivation system with refugia plants was 3,618 individuals belonging to 8 orders and 29 families. The order of insects with a composition of 41.95% was the highest composition found associated with red chili plantations with refugia plants, namely the Order Hymenoptera which is also an order of parasitoid insects found in the research area.
Paracoccus marginatus is one of the important pestson papaya. This study was conducted to evaluate the presence of one of the Chrysopa predators, Plesiochrysa ramburi to papaya invested by P. marginatus. The study used the non-factorial design with the factor of the number of predators (1, 3, 5, 7), which was released to oneovisac of P. marginatus. All treatments in the experiment had five replications. Descriptively, this study showed that the presence of Pl. ramburi, positively, affected the resilience of the plant, in this case through the mechanism of population control of P. marginatus. The presence of predators, negatively, affected P. marginatus eating behavior, which was reduced food intake behavior, which was influenced by feeding behavior. Thus it could increase plant resilience. If the presence of predators negatively affected pest eating behavior, the presence of predators could positively influence plant resilience.
The mealybug, Paracoccus marginatus is one of the important insect pests in papaya (Carica papaya L.). The high potential for damage caused by this pest poses a threat to the production of papaya in Indonesia. The aim of this study was to evaluate the intensity of P. marginatus attack on papaya by observing variables such as plant varieties, planting seasons and cultivation methods. The area of observation plots was about 2.000 m2. The cultivation technique applied was monoculture with a spacing of 2.5 m x 2.5 m. Thirty plots of plants were collected from each plot of plants using diagonal sampling technique. The total number of leaves and the number of leaves attacked were recorded. Damage intensity was determined based on the category: no attack (score 0), mild 1-25% (score 1), moderate 26-50% (score 2), severe 51-75% (score 3), and very severe 76-100% (score 4). The attack intensity was higher in the dry season than rainy season. The results show that attack was higher in the dry season that rainy season. The intensity of the attack was also higher in Thai varieties both in the rainy and dry seasons. More intensive pest control shall be applied in the dry season and in the introduced varieties.
