Abstract

Penelitian dilaksanakan di Laboratorium Entomologi dan Fitopatologi Universitas Andalas Padangdari bulan Mei sampai September 2006. Tujuan penelitian untuk mengetahui patogenisitas isolat-isolat jamurentomopatogen terhadap stadia telur dan larva hama kubis Crocidolomia pavonana. Penelitian ditata dalam rancanganacak lengkap pola faktorial dengan 2 faktor, yaitu 7 isolat ditambah 1 kontrol dan 5 stadia larva hama kubis. Hasilpenelitian menunjukkan bahwa efektivitas masing-masing isolat jamur entomopatogen berbeda nyata terhadapberbagai stadia telur dan larva hama ulat kubis. Hasil uji patogenisitas menunjukkan bahwa jamur Beauveria (isolatBAP5 dan BPP1), Nomuraea (isolat NAP3), Metarhizium (isolat MAP1), Paecilomyces (isolat PPP4), dan Fusarium(isolat FPP3) adalah jamur yang virulen terhadap telur dan larva C. pavonana. Jamur B. bassiana mempunyai potensiuntuk dikembangkan sebagai agens pengendali hama kubis pada masa mendatang.ABSTRACT. Hasyim, A., Nuraida, and Trizelia. 2009. Pathogenicity of Entomopathogenic Fungi Isolates toEggs and Larvae of Cabbage Head Caterpillar, Crocidolomia pavonana F (Lepidoptera: Pyralidae). This studywas carried out at Entomology and Phytopathology Laboratory Faculty of Agriculture, Andalas University fromMay to September 2006. The objectives of this study were to assess the pathogenicities of the entomopathogenicfungi isolates to eggs and larvae of C. pavonana. A completely randomized design with 2 factors i.e. 7 isolates ofentomophatogenic fungi with a control and 5 larvae stages of cabbage caterpillars were used. The results showedthat there were significant difference in infectivity of all isolates tested to eggs and larvae stages of the caterpillar.The isolates of Beauveria (isolate BAP5 and BPP1), Nomuraea (isolate NAP3), Metarhizium (isolate MAP1)w,Paecilomyces (isolate PPP4), and Fusarium (isolate FPP3) were more virulence to eggs and larva stages of C.pavonana. Beauveria bassiana was potential for controlling C. pavonana in near future

Abstract

Tujuan penelitian adalah untuk mengetahui preferensi petani Brebes terhadap klon unggulan bawangmerah hasil penelitian Balai Penelitian Tanaman Sayuran (Balitsa) Lembang. Penelitian dilakukan di Desa Slatri,Brebes, pada bulan Juni sampai Agustus 2003. Metode penelitian yang digunakan adalah kombinasi antara percobaanlapangan dan penelitian partisipatif petani. Percobaan lapangan dimanfaatkan sebagai petak observasi bagi 20 petanipartisipan. Percobaan lapangan menggunakan rancangan acak kelompok. Perlakuan terdiri dari 9 klon unggulanbawang merah dan kontrol varietas lokal Bima Brebes dengan 3 ulangan. Data penelitian partisipatif dikumpulkandari jawaban tertulis petani partisipan pada kuesioner yang dibagikan peneliti pada saat petani melakukan observasilapangan. Hasil penelitian menunjukkan bahwa secara agronomis, daya hasil dan ukuran umbi klon unggulan Balitsatidak lebih unggul dibanding varietas lokal Bima Brebes kecuali klon No. 9. Di antara klon unggulan yang diuji,klon No. 8 merupakan klon yang paling potensial diadopsi petani karena pertumbuhan tanaman dan hasil panennyadisukai petani. Klon No. 9 kurang disukai petani karena warnanya pucat, sehingga perlu perbaikan warna umbiuntuk meningkatkan peluang adopsi oleh petani. Preferensi petani dan pemulia terhadap klon unggulan berbedasangat nyata. Klon No. 9 yang paling disukai pemulia namun kurang disukai petani. Penelitian preferensi petaniperlu diintegrasikan dalam penelitian perakitan varietas unggul untuk meningkatkan peluang adopsi varietas unggultersebut setelah dilepas.ABSTRACT. Basuki, R.S. 2009. Farmers’ Preferences in Brebes to Shallots Promising Clones Generatedfrom IVEGRI. The objective of the research was to understand farmer’s preferences to promising shallots clonescreated by the Indonesian Vegetable Research Institute (IVEGRI). Research was conducted in Slatri, Brebes, fromJune to August 2003. A combination of field experiment and farmer’s participatory was used in the research. Thefield experiment was used as an observation plot for 20 farmer participants. The field experiment was arranged in arandomized complete block design with 3 replications. The treatments consisted of 9 promising shallots clones and alocal variety of Bima Brebes as control. Data from farmer participatory research were collected from farmer’s writtenanswers on the questionnaire distributed by researchers. Results showed that agronomically the yield and tuber sizeof the promising clones, except clone No.9, were not significantly higher or bigger than that of local variety of BimaBrebes. Among the promising clones, only clone No.8 has the potential to be adopted by farmers because farmerswas in favor with the growth and tuber quality of the clone. In order to increase the potential adoption of clone No.9improvement of the tuber color from pale red to red is needed. Farmers and breeder preferences to the promisingclones were significant difference, due to the different criteria used in evaluating the clones. Research on farmerspreference should be integrated into the research on creating a new variety to increase the potential adoption of thenew variety after released.

Abstract

Penelitian ini dilaksanakan pada bulan April-November 2006 dan ditujukan untuk melakukan simulasibesaran serta distribusi surplus ekonomik yang merupakan dampak potensial introduksi varietas unggul bawang merahdi Indonesia. Studi ini memanfaatkan teknik analisis surplus ekonomik berdasarkan asumsi sistem perekonomiantertutup dan produk tunggal bawang merah yang bersifat homogen. Perubahan teknologi yang diakibatkan olehintroduksi varietas unggul bawang merah dapat meningkatkan total dan domestik surplus sebagai konsekuensi daripeningkatan reduksi biaya dan produktivitas. Peningkatan produktivitas akan meningkatkan manfaat penggunaanteknologi varietas unggul bawang merah searah dengan dampak peningkatan reduksi biaya input per hektar. Hasilanalisis mengindikasikan bahwa inovasi varietas unggul baru ke dalam subsektor bawang merah Indonesia memilikipotensi dampak yang tinggi terhadap kesejahteraan ekonomi masyarakat. Semua skenario yang disimulasikan untukvarietas unggul bawang merah menghasilkan manfaat ekonomis tinggi. Skenario terburuk (P8) menghasilkan manfaatnasional sebesar Rp. 4,9 milyar, sedangkan skenario terbaik (P5) menghasilkan manfaat nasional sebesar Rp. 631,4milyar. Petani bawang merah masih tetap dapat memperoleh keuntungan walaupun harga satuan luarannya lebih rendah,karena teknologi baru (varietas unggul) akan meningkatkan produksi yang dapat dipasarkan dan menurunkan biayaproduksi. Tingkat adopsi varietas unggul baru bawang merah akan berpengaruh besar terhadap besaran manfaat danpada gilirannya akan bergantung pula kepada premium benih yang harus dibayar petani. Untuk petani atau perusahaanbenih, keuntungan akan meningkat sejalan dengan semakin tingginya mark-up benih dalam kondisi tertentu, tetapijuga akan menurun jika tingkat adopsinya lebih rendah. Dengan demikian, ada semacam economic trade-off antaramark-up benih dengan tingkat adopsi.ABSTRACT. Adiyoga, W., T. A. Soetiarso, M. Ameriana, and W. Setiawati. 2009. Ex-ante Assessment of PotentialBenefits for Adopting a New High Yielding Shallots Variety in Indonesia. The study carried out in April-November2006 was aimed to simulate the size and distribution of the economic surplus generated by the introduction and adoptionof new high yielding shallots variety in Indonesia. This study employed the economic surplus technique assumingthe existence of a closed economy, and dealt with a single homogeneous good. Technological change brought by theintroduction of high yielding shallots variety increased the total and domestic surplus change as a consequence ofincreases in cost reduction and yield. Increases in yield per hectare increased the benefits of the high yielding shallotsvariety technology in the same direction as increases in the cost reduction in input per hectare. The results indicatedthat high yielding variety innovations applied to Indonesia’s agricultural sector had a potential positive economicimpact and increased the society’s economic welfare. All the scenarios simulated for the high yielding shallots varietyincreased the domestic economic surplus. The worst scenario (P8) produced national benefits of Rp. 4.9 billion, whilefor the best scenario (P5), the national benefits were Rp. 631.4 billion. Shallot farmers would gain more profit evenwithout raising the output price, because the technology would increase the marketable yield and lower productioncosts. The extent of adoption of the shallots variety would largely influence the magnitude of the domestic benefitsand depend among other factors on the seed premium farmers had to pay. For the seed grower/company, profits mightincrease with higher seed mark-up under certain conditions, but through lower adoption rates they might also decrease.There was therefore an economic trade-off between the seed mark-up and the adoption rates
