Abstract

ABSTRAKSclerotium sp. merupakan jamur patogen baru pada tanamansambiloto (Andrographis paniculata Ness.) yang dapat mengakibatkankematian. Penyebaran jamur ini masih terbatas di KP Cimanggu, Bogordan KP Cicurug, Sukabumi, Jawa Barat. Tujuan penelitian adalah untukmengetahui  pengaruh  beberapa  faktor  lingkungan  seperti  suhu,kelembaban udara (RH), pH, dan cahaya terhadap pertumbuhan isolatSclerotium sp. asal sambiloto pada media PDA serta kisaran inangnya.Penelitian dilakukan di laboratorium dan rumah kaca Balai PenelitianTanaman Obat dan Aromatik (Balittro), Tahun 2005. Faktor lingkunganyang diuji yaitu suhu ruangan (20, 28, 35 dan 40) o C, kelembaban udara(RH 55, 75, 85, dan 100)%, pH (4, 5, 6, 7, dan 8) dan kondisi cahaya(terang, gelap, dan terang dan gelap selang 12 jam secara bergantian). Ujikisaran inang dilakukan terhadap 3 varietas jagung (ketan, pematung, dansokong) dan 3 varietas kacang tanah (jerapah, kelinci, dan simpai) sertatanaman sambiloto sebagai pembanding. Inokulasi dilakukan dengan caramenempelkan sclerotia jamur di bagian pangkal batang tanaman uji dekatpermukaan tanah. Pengamatan pertumbuhan jamur pada media agar yangdiperlakukan dan pengamatan intensitas serangan penyakit dilakukansetiap hari. Hasil penelitian menunjukkan bahwa isolat Sclerotium sp. asaltanaman sambiloto tumbuh baik pada suhu (20-35) 0 C, RH (55-100)%, danpada kisaran pH 4-8 serta pada kondisi terang atau gelap secara terusmenerus maupun bergantian selang 12 jam. Hasil uji kisaran inangmenunjukkan bahwa Sclerotium sp. dapat menyebabkan kematian tidakhanya pada tanaman sambiloto, tetapi juga pada dua varietas kacang tanah(simpai dan jerapah), sedangkan pada jagung tidak menyebabkan kematian(tahan). Hasil penelitian mengindikasikan bahwa isolat Sclerotium sp.yang berasal dari tanaman sambiloto mempunyai kemampuan bertahanhidup dan berkembang pada kondisi lingkungan yang luas (broadspectrum). Ketidakmampuan jamur tersebut menginfeksi tanaman jagungvarietas ketan, pematung, dan sokong dapat digunanakan sebagai salahsatu cara pengendalian patogen dengan sistem tumpangsari dan rotasi.Kata kunci : Sambiloto, Andrographis paniculata Ness, Sclerotium sp.,karakteristik, fisiologis, Jawa BaratABSTRACTPhysiological Characteristics of Sclerotium sp. Isolatedfrom SambilotoSclerotium sp. is a new destructive fungal patogen on sambiloto(Andrographis paniculata Ness.). The distribution of the patogen was stilllimited in Cicurug, Sukabumi and Cimanggu, Bogor, West Java. The aimof this experiment was to observe the growth of Sclerotium sp fromsambiloto under different environmental factors such as temperature,relative humidity, light condition, and pH on PDA medium as well as itshost range. The experiment was conducted in Indonesian Medicinal andAromatic Crops Research Institute (IMACRI) in 2005. The environmentalfactors tested were temperature (20, 28, 35, and 40) o C; relative humidity(55, 75, 85, and 100)%; pH (4-8); and light condition (continuosly on oroff and 12 hours on and off alternatively). The pathogenicity of theSclerotium sp. was tested against 3 varieties of corn (ketan, pematung, andsokong) and 3 varieties of peanut (jerapah, kelinci, and simpai) as well assambiloto as a comparison. Sclerotia of the fungus were inoculated on thestem base of the plant tested. Observation of the growth of the fungusunder different environmental factors and disease intensity on inoculatedplants was conducted everyday. The results showed that the growth ofSclerotium sp. isolate from sambiloto was affected by differentenvironmental factors. The isolate grew well at (20-35) 0 C, relativehumidity ranged from (55-100)%, pH ranged from 4-8, and lightcondition of both continuosly on or off as well as 12 hours on and offalternativelly. The isolate was pathogenic against sambiloto as well asagainst 2 varieties of peanut (simpai and jerapah), however, it was notpathogenic against all the corn varieties tested. The result indicated thatthe isolate of Sclerotium sp. from sambiloto was a broad spectrum fungalpathogen. The resistency of the corn varieties would be of value forcontrolling the disease through mixed cropping or rotation systems.Key words: Sambiloto, Andrographis paniculata Ness, Sclerotium sp.,physiological characteristics, West Java

Abstract

ABSTRAKMutasi in vitro dengan perlakuan mutagen dapat digunakan untukmeningkatkan keragaman genetika abaka melalui keragaman somaklonal.Penelitian yang dilakukan bertujuan untuk: (1) menentukan konsentrasioptimum EMS untuk induksi keragaman somaklonal dalam kultur kalusembriogen abaka, (2) meregenerasikan bibit abaka varian dari kalusembriogen yang diberi perlakuan EMS, dan (3) mengevaluasi tipe danfrekuensi keragaman karakter kualitatif dan kuantitatif di antara populasitanaman mutan abaka yang diperoleh dari regenerasi kalus embriogenyang diberi perlakuan EMS. Penelitian dilakukan mulai bulan Agustus2003 sampai Agustus 2006 di Laboratorium Kultur Jaringan dan KebunPercobaan Karangploso, Malang pada Balai Penelitian TanamanTembakau dan Serat, Malang (Balittas). Hasil penelitian menunjukkanbahwa 0,6% EMS merupakan konsentrasi optimum karena padakonsentrasi tersebut diperoleh keragaman somaklonal paling banyak.Varian yang diperoleh menunjukkan karakter kualitatif dan kuantitatifabnormal. Tipe varian tersebut umumnya bersifat negatif dan kurangmenguntungkan dibandingkan dengan populasi standar. Tipe dan frekuensikeragaman kualitatif dan kuantitatif pada klon Tangongon berbeda denganklon Sangihe-1, mengindikasikan adanya pengaruh genotipe terhadapkeragaman somaklonal. Varian dari abaka klon Tangongon denganproduksi serat tertinggi (161,0 g dan 154,0 g/tanaman) diperoleh dariperlakuan EMS 0,3% (T1 28.1.1 dan T1 11.2.2), sedangkan dari klonSangihe-1, hasil serat tertinggi (35,0 g dan 40,0 g/tanaman) diperoleh dariperlakuan EMS 0,6% (S4 28.1.0 dan S4 56.2.0). Produktivitas tersebutlebih rendah dibandingkan dengan produksi serat tanaman kontrol klonTangongon (193,0 g/tanaman) dan Sangihe-1 (70 g/tanaman).Kata kunci : Abaka, Musa textilis, keragaman somaklonal, EMS, muta-genesis, in vitro, hasil, Jawa TimurABSTRACTGenetic Variability of Abaca Variants Induced byEthylmethane Sulphonate (EMS)In vitro mutation with mutagen treatment can be used to increasethe genetic variability of abaca by inducing somaclonal variation. Theobjectives of the experiments were to (1) determine optimum concen-tration of EMS to induce abaca somaclonal variation, (2) produce abacalines from EMS treated embryogenic calli and evaluate their performancein the field, and (3) evaluate type and frequency of qualitative andquantitative variant characters among regenerated abaca lines. Thisexperiment was conducted in Tissue Culture Laboratory and KarangplosoExperiment Station of Indonesian Tobacco and Fibre Crops ResearchInstitute (ItoFCRI) Malang from August 2003 to August 2006. The resultsshowed that EMS treatment on abaca embryogenic calli induced variation,and the optimum EMS concentration was 0.6%. The variants exhibited anumber of abnormal qualitative and quantitative characters which weregenerally negative characters since they showed lower value as comparedto control population. The presence of different types of qualitative andquantitative variant characters was genotype dependent. Variants fromabaca clone Tangongon having the highest fibre yield (161.0 g and 154.0g/plant) were obtained from 0.3% EMS treatment (T1 28.1.1 and T1 11.2.2variants). While variants from abaca clone Sangihe-1 having the highestfibre yield (35.0 g and 40.0 g/plant) were obtained from 0.6% EMStreatment (S4 28.1.0 and S4 56.2.0 variants). The fibre yield of controlclones, Tangongon and Sangihe-1, were 193.0 g and 70 g/plant,respectively.Key words: Abaca, Musa textilis, induced mutation, somaclonalvariation, field evaluation, yield, East Java

ABSTRAKPegagan (Centella asiatica L.) adalah tanaman obat yangmengandung zat asiaticotik sebagai obat alzaimer dan penghalus kulit.Tanaman ini telah diperbanyak sejak tahun 2000. Penelitian dilakukan diLaboratorium Kultur Jaringan dan Rumah Kaca Kelompok PenelitiPlasma Nutfah dan Pemuliaan, Balai Penelitian Tanaman Obat danAromatik, Bogor dari bulan Januari 2000 sampai dengan Juni 2005.Penelitian ini bertujuan untuk melihat daya multiplikasi tunas setiapperiode subkultur dimulai dari tahun kedua sampai periode lima tahun.Media yang digunakan adalah MS + BA 0,1 mg/l. Pengamatan dilakukanpada jumlah tunas, jumlah daun dan visual tunas pada umur 2, 3, 4 dan 5tahun pada dua periode subkultur setiap tahunnya. Penelitian disusundengan rancangan acak lengkap, masing-masing terdiri atas 10 botol yangmerupakan ulangan dan setiap botol terdiri atas 1 eksplan. Untuk re-mediaterhadap tanaman yang terlihat berubah digunakan media MS + BA (0;0,1; 0,2; 0,3) mg/l. Selanjutnya untuk perakaran dilakukan pada media MS+ IAA (0,1 dan 0,2); MS + NAA (0,1 dan 0,2) mg/l serta MS + IBA (0,1dan 0,2) mg/l. Plantlet utuh yang terbentuk selanjutnya diaklimatisasi padamedia tanah + pupuk kandang dan tanah + sekam dengan perbandingan 1 :1. Hasil penelitian menunjukkan bahwa daya multiplikasi tunas optimumterjadi pada tahun ketiga, dan memasuki tahun keempat dan kelimamenurun yang diiringi dengan perubahan eksplan yang terlihat padatangkai daun yang terbentuk. Akar terpanjang dan terbanyak yangterbentuk didapat pada media IAA 0,2 mg/l dengan penampilan yangkurus dan rapuh. Keberhasilan aklimatisasi sangat rendah, tetapi plantletmampu beregenerasi dengan baik dan terlihat tumbuh normal. Dari hasilperbanyakan terlihat bahwa jumlah anakan, jumlah daun, panjang stolondan jumlah bunga lebih tinggi dibandingkan yang tumbuh pada mediasekam, berturut-turut : 6,77; 7,30; 46,50 cm dan 8,31. Sementara padamedia sekam komponen yang dominan adalah panjang tangkai daun yakni9,75 cm.Kata kunci : Pegagan, Centella asiatica L., multiplikasi, tunas, aklima-tisasi, penyimpanan, Jawa BaratABSRACTShoot multiplication and acclimatization of gotuloca(Centella asiatica L.) five years after conservation by invitro cultureGotuloca (Centella asiatica L.) is a medicinal crop containingasiaticotic as alzaimer and skin revitalizer.

Abstract

ABSTRAKMinyak nilam dan minyak daun cengkeh mempunyai arti pentingdalam ekspor minyak atsiri Indonesia, karena kedua jenis minyak atsiritersebut memiliki volume ekspor tertinggi. Sebagian minyak nilam danminyak daun cengkeh dihasilkan dari penyulingan yang masih mengguna-kan ketel penyuling terbuat dari logam besi, sehingga warnanya keruh dangelap. Keadaan tersebut menyebabkan kedua minyak tersebut sulit diteri-ma dalam perdagangan dan harganya lebih rendah. Minyak yang keruhdan gelap karena kontaminasi dari logam besi dapat dimurnikan dengancara kompleksometri, yaitu pengikatan logam menggunakan bahan kimiayang disebut bahan pengkelat (chelating agent). Penelitian pemurnianminyak nilam dan minyak daun cengkeh yang keruh dan gelap telahdilakukan di Laboratorium Pengolahan Hasil Balai Penelitian TanamanRempah dan Obat, Bogor, dari bulan Januari sampai April 2005.Rancangan penelitian yang digunakan adalah rancangan acak lengkap(RAL) dengan 3 perlakuan dan diulang 3 kali. Perlakuan yang diuji terdiriatas (1) jenis bahan pengkelat, yaitu etilen diamin tetra asetat (EDTA),asam sitrat dan asam tartarat; (2) konsentrasi pada masing-masingpengkelat terdiri atas 0,50%; 1,0% dan 1,50%; (3) lama waktu pengadukanyaitu 30; 60 dan 90 menit. Penilaian hasil pemurnian didasarkan padatingkat kejernihan minyak (%T), kandungan besi (Fe) dan kandungankomponen utama dalam minyak hasil pemurnian. Hasil penelitianmenunjukkan bahwa bahan pengkelat, konsentrasi pengkelat maupun lamapengadukan sangat berpengaruh terhadap tingkat kejernihan dankandungan besi dalam minyak hasil pemurnian. EDTA dapat memurnikanminyak nilam dan minyak daun cengkeh lebih baik dibanding asam sitratdan asam tartarat. Semakin tinggi konsentrasi pengkelat serta semakinlama waktu pengadukan dapat meningkatkan kejernihan minyak nilam danminyak daun cengkeh dan menurunkan kandungan besi didalam keduaminyak tersebut. Bahan pengkelat EDTA 1,50% menghasilkan minyakpaling jernih serta kadar Fe paling rendah. Pada minyak nilam kadar Feterendah 17,66 ppm dan pada minyak daun cengkeh 27,16 ppm. Kom-ponen utama dalam minyak nilam yaitu patchouli alkohol dan komponenutama dalam minyak cengkeh yaitu eugenol serta karakteristik lainnyadalam kedua minyak tersebut tidak dipengaruhi oleh perlakuan. Minyaknilam dan minyak daun cengkeh hasil pemurnian tersebut memenuhipersyaratan Standar Nasional Indonesia.Kata kunci : Nilam, Pogostemon spp., cengkeh, Eugenia aromatica,minyak nilam, minyak daun cengkeh, prosesing, pemurnian,kompleksometri, patchouli alkohol, eugenol, Jawa BaratABSTRACTPatchouly oil and clove leaf oil purification usingcomplexometry methodPatchouly oil and clove leaf oil have the biggest volume in the totalIndonesian essential oil export. Some of the oil is produced using ironmetal distilling apparatus. So that, as the result the oil produced is dirtyand has dark colour. Its quality is low and its price is lower. Purification ofthe dirty and dark oil can be carried out using complexometry method,where the iron metals are attachted by chelating agent chemical to form thecomplex compound. The purification experiment was carried out toevaluate the influence of chelating agents (EDTA, citric acid, tartaric acid)their concentration and duration of mixing on the quality of pure oilproduced. Material used was the crude patchouly oil and clove leaf oilfrom the small distilling industry in Purwokerto, Central Java. Theexperiment used a completely randomized design, arranged factoriallywith three replications. Parameters used for evaluating the effect of thetreatment were the clearness of the oil, iron (Fe) content, and the maincomponent (patchouly alcohol in patchouly oil, eugenol in clove leaf oil)of oil produced. Experiment was conducted in the Postharvest TechnologyLaboratory, Research Institute for Spice and Medicinal Crops, Bogor, fromJanuary to April 2005. The result of the experiment showed that the bestpurification method is using EDTA chelating agent of 1.50% concen-tration. Such a purification method produced the clearest oil and the lowestiron content in purified patchouly oil and clove leaf oil. Meanwhile, themain component content and other characteristics of both oil were notaffected by the treatment. Patchouly oil and clove leaf oil of thepurification method meet the Indonesian National Standard.Key words: Patchouly, Pogostemon spp., patchouly oil, clove, Eugeniaaromatica,  clove  leaf  oil,  processing,  purification,complexometry, patchouli alcohol, eugenol, West Java
