Rancangan percobaan yang digunakan adalah kelompok lengkap teracak dengan dua faktor dan empat ulangan, setiap ulangan terdiri atas empat tabung kultur yang ditanam satu eksplan. Percobaan dilakukan secara terpisah pada dua kultivar bawang merah, yaitu Bima Brebes dan Tiron. Faktor pertama adalah konsentrasi ribavirin, yaitu 0, 5, 10, 15, dan 20 mg/L. Faktor kedua adalah ukuran eksplan (shoot tip), yaitu 1,1–2,0 mm dan 2,1–3,0 mm. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ribavirin menekan tinggi tunas cv. Bima Brebes, waktu muncul daun, tinggi tunas, dan jumlah daun cv. Tiron. Ukuran shoot tip yang lebih besar (2,1–3,0 mm) dapat meningkatkan persentase tumbuh eksplan dan mempercepat waktu muncul daun pada cv. Bima Brebes dan Tiron. Konsentrasi ribavirin yang diaplikasikan pada dua ukuran shoot tip masih belum dapat mengeliminasi virus OYDV pada kedua kultivar bawang merah.KeywordsBawang merah; In vitro; Ribavirin; Shoot tipAbstractChemotherapy is an apllication of chemistry compound (ribavirin) that has antiviral activity to inhibit virus multiplication in plant tissues. The objective of the experiment was to evaluate the effect of ribavirin concentrations on shoot tip growth of shallot for OYDV eradication. The experiment was cunducted at Tissue Culture Laboratory 3, Agronomy Department and Plant Virology Laboratory, Plant Protection Department of IPB from October 2015 until June 2016. The experiment was arranged in a completely rendomized block design with two factors and four replications. Each experimental unit consisted of four bottles with one explant in it. The first factor was ribavirin concentrations, i.e. 0, 5, 10, 15, and 20 mg/L. Second factor was shoot tip sizes, i.e. 1.1–2.0 mm and 2.1–3.0 mm. The experiment showed that increasing ribavirin concentrations suppressed the shoot length of cv. Bima Brebes, and it also inhibited the time of leaf to emerge, shoot length, and leaf number of cv. Tiron. Increasing shoot tip size (2.1–3.0 mm) influenced percentage of explant growth and speed the time of leaf emergance of cv. Bima Brebes and Tiron. Ribavirin concentrations used in this treatment did not eradicate OYDV in both shoot tipe sizes of the two cultivars.","PeriodicalId":420744,"journal":{"name":"Jurnal Hortikultura","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116895496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pemilihan lokasi dan responden dilakukan secara purposive, yaitu dengan menentukan sebanyak 45 petani yang berasal dari 10 kelompok tani yang menanam krisan di masing-masing wilayah. Untuk mengetahui tingkat kepentingan kebutuhan inovasi teknologi dalam pengembangan agribisnis krisan berkelanjutan digunakan skala Likert lima tingkat, yaitu sangat penting, penting, cukup penting, tidak penting, dan sangat tidak penting. Penilaian kepentingan dilakukan berdasarkan perkiraan besarnya tingkat kepentingan suatu inovasi teknologi dalam pengembangan sistem agribisnis krisan. Penilaian pelaku usaha terhadap nilai kepentingan relatif jenis inovasi dari masing-masing subsistem agribisnis merupakan dasar pertimbangan untuk menentukan tingkat prioritas dalam program penelitian ke depan dengan kategori utama, prioritas, maupun potensial.KeywordsIdentifikasi; Inovasi teknologi; Krisan; Pelaku usahaAbstractInnovation is a key component in increasing competitiveness. Informations of technology innovation is necessary in determining the priority of research programs that meet the needs of users. The purpose of this study was to obtain information on the type of technological innovation required by business actors to develop chrysanthemum cultivation. The study was conducted in West Java, Central Java, and Bali in January-December 2014. The selection of location and respondents was done purposively by determining as many as 45 farmers from 10 farmer groups planting chrysanthemums in each region. To know the importance level of technological innovation in the development of sustainable chrysanthemum agribusiness was used five-level Likert scale, that is very important, important, important enough, unimportant, and very unimportant. Assessment of interest is based on the approximate level of importance of a technological innovation in the development of chrysanthemum agribusiness system. The appraisal of business actors on the relative importance of different types of innovation from each agribusiness subsystem is the basis of consideration to determine the priority level in future research programs with major category, priority category, and potential category categories.","PeriodicalId":420744,"journal":{"name":"Jurnal Hortikultura","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124893385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upaya untuk meningkatkan produktivitas bawang merah sesuai dengan potensi hasilnya terus diupayakan, namun terkendala oleh ketersediaan benih bawang merah bermutu dalam jumlah cukup sepanjang tahun bagi petani. Untuk mengatasi hal tersebut diupayakan dengan memproduksi biji botani bawang merah (true shallot seed =TSS). Penelitian sebelumnya menyatakan penggunaan TSS potensial untuk mengurangi biaya benih dan meningkatkan hasil panen bawang merah. Tujuan penelitian untuk mengetahui kelayakan finansial produksi biji botani bawang merah/TSS di tiga provinsi di Indonesia. Penelitian dilakukan pada bulan Juni hingga Desember 2016 di Desa Gurgur, Kecamatan Tampahan, Kabupaten Tobassa, Sumatera Utara, Desa Tulungrejo Kecamatan Bauji Kota Batu, Jawa Timur, dan di Desa Gumeng, Kecamatan Jenawi, Kabupaten Karang Anyar, Jawa Tengah.

Hasil penelitian menunjukkan bahwa produksi TSS di Sumatera Utara dan Jawa Timur memberikan keuntungan yang sangat baik, yakni sebesar 602,7 juta dan 356,3 juta rupiah dengan nilai R/C berturut-turut 3,44 dan 2,63.

Efforts for increasing shallot productivity to fit its potential yield are continuously pursued. However, these efforts are mostly constrained by the availability of high quality shallot bulb seed and its accessibility to be used by farmers along the year. An alternative planting material that recently has been promoted is the use of true shallot seed (TSS). Preliminary findings suggest a promising potential of TSS use because it may not only reduce the seed costs, but also may increase the yield. The objective of this study was to assess the financial feasibility of TSS production in three provinces of Indonesia. The study was conducted from June to December 2016 in (1) Gurgur Village, Tampahan Subdistrict, Tobassa District, North Sumatera, (2) Tulungrejo Village, Bauji Subdistrict Batu, East Java, and in (3) Gumeng Village, Jenawi Subdistrict, Karang Anyar District, Central Java. Data were analyzed by using an enterprise budget method. The results suggest that TSS production in North Sumatera and East Java provides positive profit as much as IDR 602.7 million (R/C = 3.44) and IDR 356.3 million (R/C = 2.63), respectively. Meanwhile, because of unfavorable climatic condition, TSS production in Central Java experiences a loss as much as IDR 184.3 million, with the R/C of 0.41.","PeriodicalId":420744,"journal":{"name":"Jurnal Hortikultura","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114747864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
