Abstract

Cabai merupakan salah satu komoditas pilihan bagi petani karena mempunyai nilai jual yang tinggi. Pengusahaan cabai dilakukan secara intensif tanpa mempertimbangkan prinsip pertanian berkelanjutan sehingga mengakibatkan timbulnya ledakan organisme pengganggu tanaman (OPT), penurunan kesuburan tanah, dan pencemaran lingkungan. Selain itu, introduksi sistem pertanaman monokultur dan varietas modern menyebabkan hilangnya keragaman genetik, sebagai contoh 70% spesies burung dan 49% spesies tanaman kini terancam. Hal ini diperparah oleh perubahan iklim yang meningkatkan serangan OPT dan menurunkan produksi cabai antara 25-100%. Pengendalian OPT ramah lingkungan akhir-akhir ini dikembangkan dalam usaha tani cabai untuk menurunkan penggunaan pestisida sintetis. Oleh karena itu, perlu dikembangkan teknologi yang dapat mengatasi dampak variabilitas iklim dan kejadian cuaca ekstrem. Indikator keberhasilan pengendalian OPT ramah ling-kungan ialah (1) keseimbangan ekosistem tetap terjaga; (2) biodiversitas tetap lestari; (3) residu pestisida minimal; dan (4) biaya produksi menurun. Teknologi pengendalian OPT ramah lingkungan dapat diterapkan bila pemerintah berfungsi sebagai fasilitator melalui kebijakan dengan memberikan insentif kepada produsen untuk mengadopsi cara pengendalian OPT ramah lingkungan dan insentif bagi konsumen yang mengonsumsi produk bersih. Dukungan terhadap kegiatan penelitian pengendalian OPT ramah lingkungan perlu pula ditingkatkan. Peraturan perundangan dalam diseminasi dan implementasi pertanian berwawasan lingkungan perlu pula diperkuat.

Abstract

Penggunaan insektisida kimia sintetis secara intensif di lapangan dapat mengurangi populasi musuh alami, sehingga mengakibatkan populasi hama meningkat. Bemisia tabaci merupakan salah satu hama penting pada tanaman cabai merah yang dapat menyebabkan kerusakan langsung dengan cara menghisap cairan tanaman dan tidak langsung menularkan penyakit virus kuning. Cara pengendalian yang ramah lingkungan merupakan faktor penting dalam menekan kehilangan yang diakibatkan oleh serangan B. tabaci. Penelitian bertujuan untuk mengetahui kompatibilitas insektisida nabati yang berasal dari minyak serai dengan predator Menochilus sexmaculatus dalam menekan populasi B. tabaci. Penelitian dilakukan di Laboratorium dan Rumah Kasa Balai Penelitian Tanaman Sayuran mulai bulan Juni sampai dengan Desember 2009. Penelitian menggunakan metode pencelupan (dipping method)  untuk kutukebul, film kering (dry film), dan odor effect untuk predator M. sexmaculatus. Rancangan percobaan yang digunakan ialah acak kelompok terdiri atas enam perlakuan dan empat ulangan. Perlakuan yang digunakan ialah enam konsentrasi minyak serai yaitu 5.000, 4.000, 3.000, 2.000, 1.000, dan 0 ppm sebagai kontrol. Untuk menentukan nilai LC50 dan LT50 digunakan analisis Probit. Hasil penelitian menunjukkan bahwa aplikasi minyak serai pada konsentrasi 2.000-5.000 ppm efektif menekan populasi nimfa B. tabaci instar I dan II, sedangkan untuk instar III dan IV pada konsentrasi 3.000-5.000 ppm dengan nilai penekanan sebesar 92-98% bila dibandingkan dengan kontrol. Nilai LC50 untuk nimfa B. tabaci instar I-IV berturut-turut sebesar 1.266,48, 1.755,81, 2.305,46, dan 2.343,59 ppm.  Pada konsentrasi 2.000 ppm, LT50 minyak serai  untuk nimfa B. tabaci ialah sekitar 2,95 hari setelah perlakuan. Minyak serai yang aman untuk larva predator M. sexmaculatus ialah pada konsentrasi 1.000 ppm bila diaplikasikan secara kontak dan 1.000-2.000 ppm bila diaplikasikan sebagai odor effect. Minyak serai pada konsentrasi 1.000-5.000 ppm aman terhadap imago M. sexmaculatus. Konsentrasi 2.000 ppm minyak serai merupakan konsentrasi yang sesuai diaplikasikan sebagai insektisida alami untuk pengendalian B. tabaci, aman dan kompatibel dengan  predator M. sexmaculatus. Berdasarkan hasil penelitian ini diketahui bahwa minyak serai dan M. sexmaculatus memiliki potensi dalam mengendalikan B. tabaci pada cabai.There is a tendency of diminishing  the number of natural enemies caused by utilization of non-selective insecticides that lead to serious consequences for pest population dynamics. Bemisia tabaci is an extremely polyphagous pest that causes direct damage and can act as a viral vector on hot peppers causing yellow virus disease. The activity of natural enemies can be exploited by employing propers conservation and augmentation techniques. Natural enemies might play roles to control of  B. tabaci on hot peppers. The study was conducted in the Laboratory and Screenhouse of IVEGRI from June to December 2009. The objective of this study was to determine compatibility of citronella oil with M. sexmaculatus to control B. tabaci. Dipping methods, dry film, and odor effect were used in this study. Randomized completely block design with six treatments and four replications was used in this study. The treatments were citronella oils at different consentration 5,000, 4,000, 3,000, 2,000, 1,000, and 0 ppm as a control and stages of B. tabaci (1st, 2nd, 3rd, and 4th instars) and M. sexmaculatus. Probit analysis was used to ditermine LC50 and LT50 value. The results indicated that  citronella oils at concentration of 2,000-5,000 ppm was effective to control nymphs of B. tabaci at 1st and 2nd instar , while 3,000-5,000 ppm for 3rd and 4th instar. The first two nymphal stages were more susceptible to citronella oil compared to the third and fourth nymphal stage. LC50 value for first to fourth nymphal stage was 1,266.48; 1,755.81; 2,305.46, and 2,343.59 ppm respectively. The LT50 occurred at 2.95 days in all instar stages.  Menochilus sexmaculatus  predators were  highly susceptible to the essential oil vapours and the selective toxicity ratio varied depending on the methods and stages. Citronella oil at 1,000-2,000 ppm was compatible with M. sexmaculatus larvae on odor effect and 1,000 ppm on dry film method. Menochilus sexmaculatus adult more tolerant to citronella oil compared to larvae stage at concentration 1,000-5,000 ppm. Concentration 2,000 ppm of citronella oil was the appropriate concentration applied as bioinsecticide for B. tabaci, safety and compatibility for M. sexmaculatus. Based on the study known citronella oil and M. sexmaculatus  had potential to be incorporated in controlling B. tabaci  on hot peppers.

Abstract

Liriomyza huidobrensis merupakan hama baru pada tanaman kentang. Hama ini pertama kali dilaporkan menyerangtanaman kentang di Puncak, Jawa Barat pada tahun 1994 dan diduga telah resisten terhadap berbagai jenis insektisidadari golongan organofosfat, karbamat, dan piretroid sintetik. Upaya pengendalian hama tersebut diarahkan pada pro -gram pengendalian hama terpadu (PHT). Dalam pro gram tersebut penggunaan insektisida hanya dilakukan apabilapopulasi hama sudah mencapai ambang pengendalian dan jenis insektisida yang digunakan harus selektif. Tujuanpenelitian untuk mengetahui selektivitas 13 jenis insektisida yaitu insektisida yang efektif terhadap hama L.huidobrensis tetapi tidak membahayakan parasitoid Hemiptarsenus varicornis. Metode penelitian yang digunakanadalah metode pencelupan dan umpan beracun (masing-masing terdiri atas enam konsentrasi insektisida yang diujidan empat ulangan). Data mortalitas dikoreksi menggunakan rumus Abbott. Untuk mengetahui nilai LC50 digunakananalisis probit, sedangkan selektivitas insektisida ditentukan dengan membandingkan nilai LC50 insektisida terhadapL. huidobrensis dengan nilai LC50 H. varicornis. Hasil penelitian menunjukkan bahwa insektisida bensultap 50 WP,siromasin 75 WP, dan abamektin 18 EC merupakan insektisida yang pal ing efektif (LC50 masing-masing 3,92; 7,20;dan 0,54 ppm) untuk mengendalikan L. huidobrensis dan mempunyai sifat selektif (SR<1) terhadap parasitoid H.varicornis. Insektisida klorfenapir 100 SC, dimehipo 400 WSC, dimetoat 400 EC, karbosulfan 200 EC, danamamektin 19 EC merupakan jenis insektisida yang mempunyai daya racun cukup tinggi terhadap parasitoid H.varicornis.Kata kunci : Selektivitas; Insektisida; Liriomyza huidobrensis; Hemiptarsenus varicornis; Parasitoid.AB STRACT.

Abstract

Clubroot is one of the important diseases affecting members of the Cruciferae family.  This disease is caused by soil-borne pathogen, called Plasmodiophora brassicae. The pathogen produces motile spores called zoospores. This pathogen results in a drop of cruciferous plant productivity. The objectives of this research were to identify specific Trichoderma species in three districts in Sumatra Utara and to evaluate the potency of T. harzianum (both local species from Berastagi and species developed by Indonesian Vegetable Research Institute (IVEGRI)) to control the disease and then comparing them with the application of synthetic fungicide. The research was conducted in a greenhouse of Research Installation and Application of Agricultural Technology (IP2TP), Berastagi, North Sumatera from April‒September 2018, using Completely Randomized Design (CRD) with eight treatments: C1 (control-without Trichoderma), C2 (T. harzianum IVEGRI obtained from corn substrate 2 g/polybag), C3 (T. harzianum IVEGRI obtained from rice substrate 2 g/polybag), C4 (T. harzianum IVEGRI obtained from corn substrate 4 g/polybag, C5 (T. harzianum IVEGRI obtained from rice substrate 4 g/polybag), C6 (local T. harzianum obtained from corn substrate 2 g/polybag), C7 (local T. harzianum obtained from corn substrate 4 g/polybag) and C8 (synthetic fungicide Nebijin). Each treatment contained 10 polybags of plants. These treatments were replicated four times. The results exhibited there were 3 Trichoderma species found in Berastagi: T. harzianum, T. viride and T. koningii. Also, 4 g of local T. harzianum (corn substrate) has better performance (0% disease incidence and 0% disease severity) compared to other treatments.

Abstract

This study aimed to discover the strategies for learning Arabic in increasing students' interest in studying mufrodat material for class VII Mts Al Khiriyah Bandar Lampung. The monotonous strategy causes a lack of students' interest in learning Arabic. This study used descriptive qualitative methods with student research subjects—data collection techniques using questionnaires, interviews and documentation. Interest is one of the student's internal factors significantly influencing learning success. High interest in learning will make students enthusiastic and can easily achieve the competencies to be achieved. To motivate students, certain strategies are needed in learning. This study's results indicate an increase in student learning interest in class VII Mufrodat material at MTs Al Khairiyah Bandar Lampung in terms of the results of interviews and student questionnaires. CTL (Contextual Teaching and Learning) and PAKEM (Participatory, Active, Creative, Effective) use strategies to enhance learning.
