Abstract

Purbalingga regency since five years has been the center of pepper production in Java Island. This study was conducted from May to September 2017 to analyze the financial performance of pepper farming and its economic impact on the development area. Data and information analysis is done qualitatively and quantitatively. Qualitative analysis uses cross tabulation, then interpreted descryptionally, while quantitative analysis includes: (1) RAVC and MBCR for assessing financial performance; and (2) ΔRAVC and ROI for projected potential economic impacts. The results showed that application of fertilizer technology with <50% recommended dosage only increased RAVC IDR 1.7 million/ha/year with MBCR = 1.53. RAVC contribution of mixed crops reached IDR 12.5 million/ha/year with MBCR = 3.79. The application of fertilization and multiple cropping technology encourages greater pepper productivity increase than BEP productivity and pepper prices in year 2017 is also greater than BEP price, so the application of fertilization technology provides postive benefits for the financial performance of pepper farming. The potential economic impact of pepper technology application reached IDR 1 billion/year up to IDR 3.6 billion/year with ROI = 11.37% to 81.37% may still be enhanced by: (1) encouraging the application of fertilization technology, and (2) encouraging farmers to adopt the fertilization technology and multiple cropping correctly, given that pepper productivity is still far below genetic potential. Therefore, efforts are needed to accelerate adoption of innovation.Keywords: white pepper, technology, financial performance, economic impact AbstrakKabupaten Purbalingga sejak lima tahun terkahir telah menjadi sentra produksi lada di Pulau Jawa. Teknologi budidaya yang dilakukan para petani masih beragam sehingga mempengaruhi terhadap kinerja keuangan serta dampak ekonominya. Penelitian ini dilakukan pada bulan Mei sampai dengan September 2017 untuk menganalisis kinerja finansial usahatani lada serta potensi dampak ekonomi penerapan teknologi pemupukan dan polikultur. Analisis data dan informasi dilakukan secara kualitatif dan kuantitatif. Analisis kualitatif menggunakan tabulasi silang, kemudian diinterpretasi secara deskriptif, sedangkan analisis kuantitatif meliputi: (1) RAVC dan MBCR untuk menilai kinerja finansial, dan (2) ΔRAVC dan ROI untuk proyeksi dampak ekonomi. Hasil penelitian menunjukkan bahwa penerapan teknologi pemupukan dengan <50% dosis anjuran hanya meningkatkan RAVC Rp1,7 juta/ha/th dengan MBCR=1,53. Kontribusi RAVC tanaman campuran mencapai Rp 12,5 juta/ha/th dengan MBCR=3,79. Penerapan teknologi pemupukan dan polikultur mendorong peningkatan produktivitas lada lebih besar dari pada BEP produktivitas dan harga lada pada tahun tahun 2017 juga lebih besar dari pada BEP harga, sehingga penerapan teknologi pemupukan dan polikultur memberikan manfaat posistif bagi kinerja finansial usahatani lada. Potensi dampak ekonomi penerapan teknologi pemupukan dan polikultur lada mencapai Rp 1 miliar/th sampai dengan Rp 3,6 miliar/th dengan ROI= 11,37% sampai dengan 81,37% masih mungkin ditingkatkan dengan pendekatan: (1) mendorong peningkatan areal penerapan teknologi pemupukan, dan (2) mendorong petani menerapkan teknologi pemupukan dan polikultur secara benar, mengingat capaian produktivitas lada masih jauh di bawah potensi genetis. Untuk itu diperlukan upaya untuk mempercepat adopsi inovasi secara berkesinambungan. Kata kunci: lada putih, teknologi, kinerja finansial, dampak ekonomi

Abstract

Colour alternation and et/tylene changes during ripening tobacco leaves cultivar Madura and its effect to the quality of slice Madura tobaccoThe colour change and elhylene production in the leaves of Madura tobacco (Nicotiana tabacum) during ripening was studied at "Labora¬ torium Biokimia Pusat Antar Universitas Pangan dan Gizi Universitas Gadjahmada Yogyakata" and "Laboratorium Inti dan Atom Jurusan I'isika, FMIPA Universitas Gadjahmada Yogyakata". The change of colour was measured with Chrommameter CR-200. while the production of ethylcne, ACC (1-aminocyclopropanc-l-carboxylic acid) and MACC (malonyl-ACC) were measured with Photoaccuslic Spectroscopy, from the sample of 100 kg tobacco leaves cv. Jepon grown from April to September 1995 in Plakpak, Pcgantenan, Pamekasan, East Java. The experiment was designed as a completely randomized design in three replicates. The leaves samples were taken randomly from the mature middle leaves Results showed that endogenous ethylcne production al the irst day al a level of 169 ppb. was able to initiate ripening. Conversion percentage of ACC to ethylcne for 8 days ripening increased from 7.7 up lo 61.4 %. F tests least signiicantly different (1%). showed that yellow intensity signiicantly increased on the second day. This indicated thai ripening process was stated on the second day. On the other hand green intensity significantly decreased at the ifth day, thus no chlorophyl degradation. Brightness was signiicantly observed on Ihe third day of ripening, meaning that ripening stated on the third day. Based on the three criteria, the best ripening period was from the third lo the ilth day. This implies that the farmers will have three day periods of ripening which can be arranged to overcome the shotage of man power for slicing the leaves.

Abstract

Penyakit busuk (soft rot) pada daun tanaman lidah buaya (Aloe vera) disebabkan oleh F.rwima chrysanthemi pertama kali dilaporkan di Kcpulauan Kaibia tahun 1992. Pada awal tahun 2001, gejala pcnyakil busuk daun juga ditemukan pada tanaman lidah buaya di Semplak, Jawa Barat. Mengingat kerusakan yang ditimbulkan berupa pembusukan pada daun dan pangkal batang yang parah dalam waktu singkat, maka diduga penyebabnya cukup ganas dan dikhawatirkan dapat menjadi kendala pengembangan tanaman lidah buaya yang akhir-akhir ini sedang banyak diminati. Tujuan penelitian ini adalah mengidcntifikasi penyebab penyakit tersebut. Penelitian dilakukan di Laboratorium Bakteri Balai Penelitian Tanaman Rempah dan Obat, dari bulan April - Agustus 2001. Contoh daun lidah buaya sakit berasal dari kebun petani di Semplak, Bogor. Setelah melalui pengamatan gejala penyakit diikuti dengan prosedur isolasi dan pemumian patogen. maka diperoleh isolat kultur baktei yang bentuknya bulat dan pinggirnya tidak rata serta berwarna putih pada medium sukrosa pepton agar. Kultur baktei tersebut bersifat patogenik dan menimbulkan gejala penyakit sama seperti di lapangan, setelah diinokulasikan melalui pelukaan pada daun lidah buaya. Hasil karaktcrisasi morfologi, kultur dan biokimia isolat baktei tersebut menunjukkan sifat ncgatif untuk pewamaan Gram, pigmen fluorescn, oksidasc, dan produksi asam dari unsur karbon laktosa dan dulsitol. Sedangkan karaktcr positif diperoleh dai pengujian oksidasi/fermentasi, lesitinase, pembusukan jaringan umbi kentang, sensitivitas terhadap eitromisin, pertumbuhan pada suhu 37° C, NaCI 5%, serta menghasilkan asam pada medium mengandung manitol Inokulasi pada umbi ubi jalar menyebabkan pembusukan dalam waktu yang singkat. Berdasarkan data tersebut dapat disimpulkan bahwa penyebab penyakit busuk daun pada tanaman lidah buaya di Semplak adalah Erwinia chrysanthemi.Kata kunci: Aloe vera, busuk daun, Erwinia chrysanthemi, Bogor ABSTRACT Characteristics o/Envinia chysanthemi causing bacterial soft rot ofAloe (Aloe VeraJThe bacterial sot rot of aloe, caused by Erwinia chrysanthemi, was first identified in Caibbean Island in 1992. In early 2001, similar symptoms were found on the aloe plants grown in Semplak, Bogor, West Java. Based on its symptom and progressively spread, especially on the leaf and basal stem, it appeared that the disease was serious and therefore threatened the current development of die plants. This study was conducted in the laboratory of the Research Institute for Spice and Medicinal Crops, Bogor, in April - August 2001. The objective of the study was identifying the cause of the sot rot disease of aloe in Semplak, Bogor. Diseased leaves of aloe were obtained from Semplak. Following the examination of the symptoms, isolation and purification of he causal agent, the bacteial isolates were found. They were round, white colony characteistics on sucrose peptone agar medium. The isolate was pathogenic and caused similar disease symptoms following the artificial inoculation on the wounded aloe leaf. Based on the morphological, cultural, and biochemical analyses of the isolates, it was found that the isolates gave negative reactions for die following characteistics: Gram staining, production of fluorescent pigment, oxidase, and production of acid reaction from lactose and dulcitol. The isolates, on the other hand, gave positive reaction from: oxidation/fermentation, IcciOiinase. and maceration of potato and sweet potato, sensitive to crythromycin, growth at 37 °C, and growth on agar medium containing NaCI 2%, as well as acid production from manmtol. Based on these data, it can be concluded that the pathogen causes sot rot of leaf of aloe in Semplak is Erwinia chrysanthemi. This is the irst repot on (he finding of die disease in Indonesia. More attention is required to stop the spread of the disease.Key words: Aloe vera, sot rot. Erwinia chrysanthemi, Bogor

Abstract

Vanilla shoot rot disease (VSR) is one of important disease that potentially reduces Indonesia’s vanilla production. The VSR disease is prevalently developing in the nursery, but due to the extreme climate change, the disease occurrence in the garden has increased recently. A present study was aimed to assess the effectiveness of Trichoderma sp. and non-pathogenic Fusarium (NPF) in controlling the VSR disease in the garden. An experiment  was conducted in a vanilla garden at KP Sukamulya, Sukabumi November 2015 - July 2016.   The study consisted of five treatments that were application of Trichoderma sp. substrate (T) onto the vanilla tips, spraying the conidial suspension of FusNP (F), a combine application of Trichoderma sp. and FusNP (TF), synthetic fungicide mancozeb (M)  and the control (K). The treatments were arranged in a randomized block design, replicated five times each.  The variables measured were the incidence and severity of VSR diseases monthly, residue of synthetic fungicides and rainfall. The results showed that application of Trichoderma sp. sp. and NPF  reduced  the disease severity of VSR   3 % and 5 % respectively than the one of control. While the fungicide application was 3% lower than the control.   The VSR disease progress is affected significantly by rainfall period.  Keyword: vanilla shoot rot disease, Phytophthora capsici. Bioagent. AbstrakPenyakit busuk pucuk vanili (BPV) merupakan salah satu penyakit penting vanili yang  berpotensi mengurangi  produksi  vanili di Indonesia.  Penyakit  BPV di Indonesia umumnya merusak pembibitan, namun akibat perubahan iklim yang ekstrim, serangan penyakit BPV pada tanaman vanili dewasa di kebun mengalami peningkatan. Penelitian dilakukan untuk mengetahui keefektifan Trichoderma sp. dan Fusarium non patogenik (FusNP) dalam mengendalikan penyakit BPV di kebun vanili. Penelitian lapangan dilakukan di KP Sukamulya, Sukabumi mulai November 2015 - Juli 2016. Pengujian residu fungisida sintetik dilakukan di Laboratorium Residu Bahan Agrokimia Balai Penelitian Lingkungan Pertanian, Laladon Bogor. Penelitian terdiri atas lima perlakuan yaitu pemberian substrat Trichoderma sp. (T), penyemprotan suspensi konidia FusNP (F), kombinasi Trichoderma sp. dan FusNP (TF),  fungisida sintetik mancozeb (M) dan kontrol (K). Perlakuan disusun dalam rancangan acak kelompok (RAK), tiap perlakuan diulang sebanyak lima kali. Variabel yang diamati adalah gejala dan keparahan penyakit, curah hujan, dan residu fungisida sintetik. Data dianalisis dengan Uji Tukey pada selang kepercayaan 95%. Hasil penelitian menunjukkan bahwa Trichoderma sp. dan FusNP cukup efektif mengendalikan penyakit BPV di lapangan, setara dengan keefektifan fungisida sintetik yaitu kejadian penyakit berkisar 2 - 5%, sedangkan kontrol mencapai 32%. Perkembangan penyakit BPV dipengaruhi oleh curah hujan, semakin tinggi curah hujan semakin tinggi intensitas serangan penyakit BPV. Penggunaan fungisida sintetik secara intensif menyebabkan pencemaran lingkungan berupa residu pestisida pada daun, buah, dan tanah rizosfer vanili..Kata kunci: busuk pucuk vanili, Phytophthora. capsici, agens hayati. ABSTRACTVanilla shoot rot disease (VSR) is one of important disease that potentially reduces Indonesia’s vanilla production.
