Abstract

ABSTRAKAreal pertanaman kapas di Indonesia tersebar di enam propinsi yaituJawa Tengah, Jawa Timur, Bali, Nusa Tenggara Barat, Nusa TenggaraTimur, dan Sulawesi Selatan. Pengembangan kapas 70% berada di lahantadah hujan dan 30% di lahan sawah sesudah tanaman padi. Di lahan tadahhujan biasanya kapas ditanam setelah jagung, kedelai atau kacang hijaudan selalu mengalami kendala kekurangan air selama pertumbuhannya.Karena kendala tersebut, produksi kapas berbiji ditingkat petani umumnyahanya mencapai 200 – 500 kg per hektar. Penelitian uji multilokasidilaksanakan di Asembagus dan Wongsorejo (Jawa Timur), Bayan (NusaTenggara Barat), dan Bantaeng serta Bulukumba (Sulawesi Selatan), dilahan tadah hujan pada tahun 2004 – 2006. Sebanyak 9 galur dan varietasKanesia 8 disusun dalam rancangan acak kelompok yang diulang 4 kali(tiga ulangan tidak mendapatkan tambahan pengairan setelah tanamanberumur 42 hari atau setelah pemupukan kedua), satu ulangan diberipengairan optimal sampai panen, yang digunakan untuk menghitungIndeks Kepekaan Terhadap Kekeringan. Kapas ditanam secara monokulturpada petak percobaan berukuran 50m 2 dengan jarak tanam 100 cm x 25cm, satu tanaman per lubang. Pengamatan yang dilakukan adalah : hasilkapas berbiji pada kondisi keterbatasan air, hasil kapas berbiji padakondisi pengairan optimal, indeks kerentanan terhadap kekeringan, skorkerusakan daun akibat serangan Amrasca biguttula, dan mutu serat. Padakondisi tidak mendapatkan tambahan pengairan, rata-rata potensi hasilgalur-galur yang diuji tidak berbeda nyata dengan varietas Kanesia 8 sertatoleran terhadap A biguttula dan mutu seratnya memenuhi syarat untukindustri tekstil di Indonesia. Galur-galur yang produktivitasnya mencapailebih dari 1.500 kg kapas berbiji/ha adalah (135x182)(351x268)9,(135x182)(351x268)10, dan (135x182)10. Dilihat dari produktivitas, keta-hanan terhadap A. biguttula, ketahanan terhadap kekeringan dan mutuserat, terdapat dua galur harapan yang dapat dilepas sebagai varietas baruyang sesuai untuk dikembangkan di lahan tadah hujan pada kondisi keter-batasan air yaitu galur {(135x182)(351x268)}9 dan galur (339x448)2.Keunggulan galur {(135x182)(351x268)}9 adalah lebih toleran terhadapkondisi dengan ketersediaan air terbatas dibandingkan dengan Kanesia 8,sedangkan produktivitas, ketahanannya terhadap A biguttula, serta mutuseratnya tidak berbeda. Keunggulan galur (339x448)2 dibandingkandengan Kanesia 8 adalah mutu seratnya lebih tinggi, sedangkan produk-tivitas serta ketahanannya terhadap keterbatasan air dan A. biguttula tidakberbeda.Kata kunci : Kapas, produktivitas, mutu serat, tahan terhadap kekeringanABSTRACTNew cotton lines adaptive to rain-fedCotton growing area in Indonesia extended in six provinces i.e.East Java, Middle Java, Bali, West Nusa Tenggara, East Nusa Tenggaraand South Sulawesi. Cotton area in Indonesia is mostly (70%) in rain-fed, and the rest is on rice-field after paddy (30%). On rain-fed areas,cotton is commonly grown after maize, soybean, or greenbean, that itsuffers from drought. This condition has resulted low yield ranging 200 –500 kg seed cotton per hectare. As a result, farmers income and farmersinterest in cotton cultivation are low . Multilocations trial were conductedin Asembagus and Wongsorejo (East Java), Bayan (West Nusa Tenggara),and Bantaeng as well as Bulukumba (South Sulawesi), on rain-fed area in2004 to 2006. 9 lines of cotton and Kanesia 8 were arranged in randomizedblock design with four replications three replications without irrigation 42days after planting and one replication with optimal irrigation for theestimation of drought susceptibility index. Monoculture cotton was grownin plots sized 50 m 2 with 100 cm x 25 cm plant spacing, one plant perhole. Parameters observed were seed cotton yield on water limitedcondition, seed cotton yield on full irrigation, drought susceptibility index,score of leaf damage caused by Amrasca biguttula, and fibre quality.Means of productivity level of the cotton lines on water limited conditionwere not significantly different to Kanesia 8, all of them were tolerant toA biguttula with fiber quality was suitable for textile industries inIndonesia. There were three lines reached productivity more than 1,500kg/ha i.e. (135x182)(351x268)9, (135x182) (351x268)10, and (135x182)10. From the trials, there were two promising lines i.e. lines(135x182) (351x268) 9 and (339x448) 2 which can be released as newvarieties tolerant to water limited condition. Lines (135x182)(351x268) 9was more tolerant to water limited condition than Kanesia 8, and it was notsignificantly different in productivity, tolerancy to A biguttula, and fibrequality. Lines (339x448)2 was superior on its fiber quality than Kanesia 8and its productivity as well as its tolerancy to water limited condition andA biguttula were not significantly different.

Buahnya diketahuimengandung minyak atsiri yang didominasi senyawa trans-anethol (90%)dan berkhasiat sebagai antiseptik, antispasmodik, antikanker, karminatif,pelega tenggorokan, obat bronkitis, serta digunakan dalam pembuatansabun, parfum, pasta gigi, juga krim kulit. Sebagai tanaman bernilaiekonomi, upaya perbanyakan anis perlu dilakukan. Perbanyakan secara invitro dengan teknik kultur jaringan merupakan salah satu metode alternatifyang dapat digunakan untuk menghasilkan bibit dalam jumlah banyak,seragam dan dalam waktu yang relatif singkat. Dengan penambahansitokinin sintetik tipe urea seperti thidiazuron (TDZ) dan tipe purin sepertibenzil amino purin (BAP) akan memacu inisiasi dan proliferasi tunas.Penelitian ini bertujuan mendapatkan media yang tepat untuk menginduksitunas anis yang optimal dengan penambahan BAP atau TDZ, mengetahuirespon pertumbuhan dan penampakan kultur akibat penambahan berbagaikonsentrasi BAP atau TDZ, serta mempelajari sinergisme yang terjadiantara keduanya. Pada tahap inisiasi, eksplan berupa tunas pucuk diinduksidi dalam media MS padat dengan penambahan BAP (0,1 mg/l; 0,2 mg/l;0,3 mg/l; 1 mg/l; 2 mg/l; 3 mg/l), atau TDZ dengan kisaran konsentrasiyang sama. Tunas terbanyak yang dihasilkan dari dua jenis sitokinin padatahap ini disubkultur ke dalam media yang ditambahkan jenis sitokininyang berbeda (TDZ ke BAP atau BAP ke TDZ) pada konsentrasi 0,3 mg/latau 3 mg/l. Pada media yang ditambahkan TDZ dihasilkan tunas anislebih banyak (3,62-6,28) dibandingkan pada media yang ditambahkanBAP (1,86-2,78), tetapi tunas yang dihasilkan pendek (roset). Sedangkantunas yang dihasilkan dalam media yang ditambahkan BAP beruas lebihtinggi tetapi jumlah tunasnya sedikit. Subkultur tunas anis ke dalam mediayang diperkaya dengan sitokinin yang berbeda meningkatkan jumlah tunasyang berproliferasi dan memperbaiki visual tunas.Kata kunci: Anis, Pimpinellla anisum L. ,  minyak atsiri, multiplikasi tunas,in vitro, TDZ, BAP, Jawa BaratABSTRACTApplication of purine and urea types of cytokinins inshoot multiplication of Anise (Pimpinella anisum L.) invitroPimpinella anisum L. or sweet anise is an annual–herbaceous plantbelongs to the Umbelliferae family. The fruit of anise contains of essentialoil, which is mainly consisted of trans-anethol (90%). Essential oils ofanise is mainly used as an antiseptic, antispasmodic, anticancer,carminative, expectorant and has also been used as component in soap,perfumery, tooth paste, and skin cream productions. Since this crop ismainly cultivated in sub tropical region, anise cultivation in Indonesia hasnot been performed. To obtain sufficient numbers of anise plantingmaterials in vitro propagation was conducted by applying benzyl aminopurine (BAP) and thidiazuron (TDZ). In this research TDZ or BAP wereapplied at various concentrations (0,1 mg/l: 0.2 mg/l; 0.3 mg/l; 1 mg/l; 2mg/l; 3 mg/l), to induce shoots in MS-solid culture media. The highestnumber of shoots obtained in those two type of cytokinins containingmedia from the initiation stage were subcultured into the mediasupplemented with different cytokinins (TDZ to BAP or BAP to TDZ) at0.3 mg/l or 3 mg/l levels. The results showed that medium with theaddition of TDZ resulted in higher numbers of shoot (3,26-6,28) than thatof medium with an addition of BAP (1,86-2,78). However, rosette shootswere dominant in TDZ containing medium. On the other hand, mediumwith an addition of BAP resulted in less numbers of shoots with tallernodes. Subculture of anise into different kinds of cytokinins increased thenumbers of proliferated-shoots and recovered the abnormal shoots.Key words : Anise, Pimpinellla anisum L, essential oils, shootsmultiplication, in vitro, TDZ, BAP, West Java

Field experiment on andrographis was conducted atCicurug Research Station from June to December 2006. The aim of thisexperiment was to obtain optimum dose of organic and natural fertilizersof andrographis – corn cropping pattern. The experiment was conductedusing factorial randomized block design and three replications, where theplot size was 3 m x 4 m and planting space was 30 cm x 40 cm. The firstfactor was cropping systems i.e. (1) P0 = monoculture and (2) P1 =intercropping of andrographis and corn (planting space of corn was 150cm x 20 cm), while the second factor was dose of organic and naturalfertilizers per hectare, i.e.: (a) D1 = 10 ton compost + 300 kg rockphosphate + 60 kg biofertilizer, (b) D2 = 10 ton compost + 300 kg rockphosphate + 60 kg biofertilizer + 300 kg zeolite, (c) D3 = 10 ton compost+ 500 kg rock phosphate + 60 kg biofertilizer, (d) D4 = 10 ton compost +500 kg rock phosphate + 60 kg biofertilizer + 300 kg zeolite, (e) D5 = 20ton compost + 300 kg rock phosphate + 60 kg biofertilizer, (f) D6 = 20 toncompost + 300 kg rock phosphate + 60 kg biofertilizer + 300 kg zeolite,(g) D7 = 20 ton compost + 500 kg rock phosphate + 60 kg biofertilizer, (h)D8 = 20 ton compost + 500 kg rock phosphate + 60 kg biofertilizer + 300kg zeolite, (i) D9 = 10 ton manure + 200 kg Urea + 200 kg SP36 + 100 kg.Treatment D9 is a recommended fertilizers dose, which was used as acomparative dose. The result showed that cropping pattern and naturalfertilizers dosage did not affect growth parameters, except number ofbranch. Cropping pattern and natural fertilizers dosage significantlyaffected number of branch. The highest number of branch of 32.92 wasachieved on fertilizers dosage of 10 ton compost + 500 kg rock phosphate+ 60 kg biofertilizer. The treatments significantly affected yield ofsymplicia of andrographis. The yield of symplicia of monoculture systemat the first harvest was 507.07 kg/ha and the second was 797.56 kg/ha,which was 18% and 15% higher than that of intercropped system. Yield ofcorn ranged between 3,278 kg/ha and 4,134 kg/ha. At the first harvest, thehighest symplicia yield (614.87 kg/ha) was achieved at the treatment ofinorganic recommended dosage, while at the second harvest the highestyield of andrographis symplicia (896.63 kg/ha) was obtained from thetreatment of 20 ton compost + 300 kg rock phosphate + 60 kg biofertilizerdan 300 kg zeolite. This value, however, was not significantly different tothe yield of the treatment of 10 ton compost + 300 kg rock phosphate + 60kg biofertilizer + 300 kg zeolite, which was 835.10 kg/ha.

Abstract

Morphological and physiological characteristics of Vinca at di fferent water stress levelsVinca (Vinca rosea L.) is one of the important medicinal crops as the sources of raw materials for traditional medicines. Its alkaloid is believed can reduce the risk of cancer, blood tension and diabetes diseases. Recently, vinca is only grown as ornamental plant in the garden, therefore, its cultivation methods is limited, especially its water stress tolerance, lite purpose of this experiment was to study the effect of water stess on the morphological and physiological characteristics of vinca. A pot experiment was conducted in the plastics house of the Research Institute for Spice and Medicinal Crops from November 1997 to March 1998. Factorial experiment consisted two factors and three replications was arranged in a randomized block design. Ihe irst factor consisted of two vinca varieties, those wee white flowers (WFV) and red flowers of vinca (RFV). While 4 different levels of water stress i.e., (I) 100% ield capacity (FC), (2) 80% FC, (3) 60% FC, and (4) 40% FC were used as the second factor. Parameters used for evaluating the effect of teatment consisted of morphological characteristics such as (I) plant height, (2) number of primary branches, (3) number of leaves, (4) leaf area (5) dry weight of stem, (6) dry weight of leaf, (7) dry weight of flowers and (8) dry weight of roots, and physiological characteristics observed including: (I) percentages of opened stomata and (2) free proline content of leaf. Results showed that interaction between varieties and water stress did not significantly affect the morphological nor physiological characteristics. Varieties significantly affected the morphological characteristics (except plant height), however they did not signiicantly affect physiological characteristics. Water stress significantly affected the morphological (except dry weight of roots) and free proline contents. Under 80% FC, vinca produced the highest growth and dry weight of plant however, the plant growth and dry weight wee inhibited under 60 and 40% FC. Under 40% FC, percentages of opened stomata deceased signiicantly. Moeover, proline content in the leaves signiicantly increased by water stess treatments.

Abstract

ABSTRAKMinyak goreng merupakan salah satu komoditas penting penghasildevisa bagi Indonesia. Penelitian ini bertujuan untuk mengkaji dampakkebijakan domestik dan perubahan faktor eksternal terhadap industriminyak goreng Indonesia, dengan pendekatan sistem yang menggunakanmodel ekonometrika dalam bentuk persamaan simultan. Data yangdigunakan adalah data sekunder yang terkait dengan produksi, volume danharga perdagangan domestik, volume dan harga ekspor, dalam bentuk dataderet waktu tahun 1978-2001. Pendugaan parameter dilakukan denganmetode two stage least squares (2SLS). Untuk mengevaluasi dampakkebijakan domestik dan perubahan faktor eksternal, dilakukan simulasimodel untuk periode 1992-1996 yang menggambarkan kondisi sebelumterjadi krisis ekonomi, dan 1998-2001 menggambarkan kondisi saat terjadikrisis ekonomi. Hasil simulasi menunjukkan bahwa peningkatan hargaCPO di pasar dunia pada kedua periode menyebabkan peningkatan ekspor.Kebijakan pengenaan pajak ekspor minyak sawit mentah (CPO) danpeningkatan harga minyak goreng sawit domestik cukup efektif menekanekspor. Pada periode 1992-1996 kebijakan pengenaan pajak ekspor CPOmenyebabkan penurunan penerimaan devisa 1,114 persen (Rp 17,092miliar). Peningkatan harga minyak goreng domestik pada periode 1992-1996 menyebabkan penurunan penerimaan devisa 21,458 persen (Rp329,187 miliar) tetapi pada periode 1998-2001 dampak tersebut dinetralisiroleh penurunan nilai tukar rupiah terhadap US$. Implikasi dari kondisidemikian adalah perlunya optimalisasi pajak ekspor. Penetapan pajakekspor pada tingkat yang menyebabkan penurunan penerimaan devisasebaiknya tidak dilakukan. Dampak peningkatan ekspor terhadappenurunan ketersediaan bahan baku minyak goreng domestik dapatdiminimalkan dengan mendorong reorientasi pasar minyak kelapa mentah(CCO) dari ekspor ke pasar domestik. Langkah yang diperlukan adalahmenghidupkan kembali industri kelapa dengan pengembangan industripengolahan lanjut minyak goreng berbahan baku CCO, seperti oleokimia,sehingga meningkatkan nilai tambah dan memberi insentif bagi petani danpelaku industri kelapa.Kata kunci : Minyak goreng, kebijakan domestik, faktor eksternal, modelekonometrika, simulasi kebijakan, penerimaan devisaABSTRACTThe impacts of domestic policy and external factorchanges on Indonesian cooking oil industriesCooking oil is an important commodity in the Indonesian economy,because of its role in foreign exchange revenue. The objective of this studyis to analyze the impacts of domestic policy and external factor changeson trade and foreign exchange revenue of Indonesian cooking oil industry.The study was conducted using a system approach by formulating aneconometric model of cooking oil industry, utilizing secondary data relatedto production, volume and price in domestic trade, export volume andprice, etc, in the time series for the period of 1978 to 2001. Two stageleast squares method was used for estimating the parameters. The result ofthis study showed that increasing world price of CPO would lead toimprove foreign exchange revenue. However, export tax on crude palm oiland increase of cooking oil domestic price effectively decreased theexport. In the period of 1992 to 1996 export tax policy on CPO decreased1,114 percent (Rp 17,092 miliar) of foreign exchange revenue. Increase ofcooking oil domestic price in the period of 1992 to 1996 caused foreignexchange revenue decrease 21,458 percent, but in the period of 1998 to2001 this impact was netralized by exchange rate of US$ to rupiah. Thoseimplicated that export tax must be optimalized. The impact of exportencrease on domestic supply of cooking oil raw material could beminimized by pushing CCO market oriented from export to domesticmarket and developing final process industry of coconut, for exampleoleochemical industry, to improve added value and incentive for thefarmers and for stakeholders.Key words : Cooking oil, domestic policy, external factor, econometricmodel, policy simulation, foreign exchange

Abstract

Evaluation of phenols and lignin in the root of hybrid patchouli (Pogostemon cablin Benth.) front protoplast fusionOne of the problems faced in patchouli production is nematode infection (Pratylenchus brachyurus). Improvement of the plant resistance to nematode in patchouli is dificult 10 be conducted through conventional method as the plant never llowcrs. One of the methods of improving (he plain resistance is by using protoplast fusion of Aceh patchouli (Pogostemon cablin, cv Sidikalang ) and Java patchouli (/' heyneanus. cv (iirilaya). It has been found thai Ihe plain resistance lo nematode is closely related to phenols and lignin content of the root Therefore. Ihe level of resistance of different clones of somatic hybrids lo nematode was approached by evaluating ihe content of phenols and lignin of the roots The study was conducted al the laboratory of the Research Institute for food Crop Biotechnology, Bogor in November 2000. Phenol content was determined with high performance liquid Chromatography (IIPI.C). while lignin content was determined with Klasou method. Result showed that Java patchouli (Girilaya) contained phenols and lignin respectively 76.53 and 21 900 pp. higher than those of Aceh patchouli (Sidikalang and Tapak Tuan) respectively 38 2-81 45 and 8 000-7 200 ppm. Phenol and lignin content in the somatic hybrids were dilferenl in Ihe respective pairs. In the fusion of Girilaya x Sidikalang. all clones contained phenol lower than those of Iheir parents, some clones (29%) contained lignin higher than Sidikalang but lower than (iirilaya. and the rest (71%) contained lignin lower than the two parents. Meanwhile, from Ihe fusion of Girilaya, Tapak Tuan. I clone (4%) contained phenols higher than those of (he two parents (97 ppm). 39% contained phenols higher than Tapak Tuan but lower than Girilaya (38.75-60.12 ppm) and the rests (60%) contained phenol lower than the two parents. Furthermore, the lignin content, of 78% somatic hybrids was lower than Girilaya but higher than Tapak Tuan, but the rest (22%) was lower than the two parents. Based on the distribution of phenols and lignin content. Ihe somatic hybrids can be categorized in three group The irst groups (5 clones) contained high phenols (higher than the average). Ihe second group (9 clones) contained high lignin. and Ihe third (I clone) contained high phenol and lignin.

Abstract

ABSTRAKTanaman kapas dengan bentuk daun yang menjari (okra) diharapkanbisa dikembangkan dengan sistem tanam rapat untuk meningkatkan hasilkapas berbiji. Penelitian lapang dilakukan di Kebun Percobaan Asem-bagus, Situbondo, Jawa Timur mulai Februari-Juli 2007 dan bertujuanuntuk mengetahui kesesuaian galur kapas berdaun okra pada sistem tanamrapat. Sistem tanam rapat yang dimaksud adalah sistem tanam monokulturdengan jarak tanam dalam barisan dirapatkan yaitu dengan jarak tanam100 cm x 10 cm (100.000 tan/ha). Percobaan disusun dalam rancanganacak kelompok dengan 3 ulangan dan 1 ulangan monokultur dengan sistemtanam normal (100 cm x 25 cm; 40.000 tan/ha). Perlakuan terdiri dari 14galur/varietas kapas yang terdiri atas 12 galur berdaun okra dan 2 varietasberdaun normal (Kanesia 8 dan Kanesia 13) sebagai pembanding.Paramater yang diamati adalah tinggi tanaman, lebar kanopi, jumlahcabang generatif, jumlah buah/tanaman setiap bulan mulai 60-120 HST.Bobot buah, jumlah buah terpanen dan hasil kapas berbiji diamati saatpanen. Hasil penelitian menunjukkan bahwa peningkatan populasi tanam-an menurunkan jumlah cabang generatif, jumlah buah dan bobot buah pertanaman. Semua galur okra yang dicoba pada sistem tanam rapat rata-ratahanya meningkatkan hasil kapas berbiji 2,12% dibanding pada populasinormal. Rata-rata hasil kapas berbiji galur okra pada populasi rapat adalah2.315,8 kg/ha dan pada populasi normal 2.293,2 kg/ha. Selanjutnya hasilkapas berbiji berdaun normal Kanesia 8 dan Kanesia 13 pada populasirapat masing-masing 2.159 dan 2.179 kg/ha dan pada populasi normal1.983 kg/ha dan 2.525 kg/ha. Galur okra 98040/3 dan 98048/2 menghasil-kan produksi tertinggi pada populasi rapat (masing-masing 2.640 kg/hadan 2.627 kg/ha) dan pada populasi normal (2.688 kg/ha dan 2.807 kg/ha).Kedua galur okra tersebut mempunyai potensi hasil yang lebih tinggidibanding kapas berdaun normal (Kanesia 8 dan Kanesia 13) baik padapopulasi rapat maupun populasi normal.Kata kunci: Gossypium hirsutum L., tanam rapat, daun okraABSTRACTSuitability of Cotton Lines with Okra Leaves UnderNarrow Interrow SpacingOkra leaf cotton crop may have a potential increase in the seedcotton yield under narrow inter row spacing. Okra leaf cotton lines weretested in relative performance under high interrow spacing. The field trialwas conducted at the Asembagus Experimental Station, Situbondo, EastJava from February to July 2007. Okra leaf cotton lines were planted asmonocrop with plant spacing of 100 cm between rows and 10 cm withinrows (100,000 plants/ha). Experiment was arranged in a randomized blockdesign with three replicates. In addition, one plot was allocated formonocrop with normal inter row spacing (100 cm between rows and 25 cmwithin rows; 40,000 plants/ha). Fourteen selected cotton lines consistingof 12 lines with okra leaf and 2 varieties (Kanesia 8 and Kanesia 13) withnormal leaf as check varieties were tested. Cotton plant height, canopywidth, number of fruiting branches, and boll/plant were measured monthlyfrom 60-120 dap. Boll weight, number of harvested bolls, and seed cottonyield were counted at harvesting. Results showed that increased plantdensity resulted in reduced fruiting branches, boll count, and boll weight.The okra leaf cotton under high crop density system showed a yieldincrease by 2.12% compared to normal spacing. Average seed cotton yieldunder narrow interrow spacing was 2,315.8 kg/ha and the average yieldunder normal interrow spacing was 2,293.2 kg/ha. Okra lines cotton98040/3 and 98048/2 showed the highest yield under narrow interrowspacing (2,640 and 2,627 kg/ha) and under normal interrow spacing (2,688kg/ha dan 2,807 kg/ha). Both lines offered higher yield than those withnormal leaf under high interrow spacing and normal population.Key words: Gossypium hirsutum L., high interrow spacing, okra leaf
