Abstract

ABSTRAKPenelitian lapang dilakukan di Kebun Percobaan Balai PenelitianTanaman Tembakau dan Serat di Muktiharjo, Pati dengan tekstur tanah liatberdebu mulai tahun 2007 sampai 2009. Penelitian bertujuan untukmengetahui respon pengairan terhadap produksi dan kadar minyak bijijarak pagar. Jarak pagar ditanam pada bulan Februari 2007. Percobaanmenggunakan rancangan petak berjalur dengan tiga ulangan yang terdiridari dua faktor, yaitu faktor pertama : provenan IP-1A, IP-1M, dan IP-1P,dan faktor kedua yaitu kriteria pengairan : kontrol (tanpa pengairan),pengairan saat kandungan air tanah mencapai 35, 50, dan 65%. Pengairandiberikan selama musim kemarau. Pemangkasan pertama dilakukan padatahun II yaitu awal musim hujan (September 2008). Hasil penelitianmenunjukkan bahwa tambahan pengairan hanya diperlukan pada tahunpertama. Produksi biji jarak pagar tidak dipengaruhi oleh irigasi mulaitahun II sehingga tanaman jarak pagar tidak memerlukan tambahanpengairan selama musim kemarau dan dapat beradaptasi pada berbagaiketersediaan air tanah terutama pada daerah dengan curah hujan tahunan1.200-1.500 mm. Produksi biji IP-1P pada tahun I mencapai 258,7 kg/halebih tinggi dibanding IP-1A yaitu 148,11 kg/ha bila diairi saat kandunganair tanah 65%. Bila tidak diairi atau pengairan terbatas, produksi biji IP-1Adan IP-1P akan menurun masing-masing 37-59 dan 17-31%. Pada berbagaiperlakuan pengairan pada tahun II dan III, kisaran produksi biji 842-975dan 818-966 kg/ha. Pada tahun II, tanaman IP-1P menghasilkan produksibiji tertinggi (1.369 kg/ha) dibanding IP-1A (737 kg/ha) dan IP-1M (631kg/ha). Selanjutnya pada tahun III, produksi biji IP-1P (1.268 kg/ha) tetaplebih unggul dibanding IP-1A (902 kg/ha) dan IP-1M (416 kg/ha).Keunggulan IP-1P dibanding provenan lainnya adalah kemampuannyayang lebih tinggi dalam membentuk cabang produktif dan buah. Tambahanpengairan selama musim kemarau pada tahun I selain untuk meningkatkanproduksi biji juga meningkatkan kandungan minyak biji IP-1A dari 27,26menjadi 29,89% dan IP-1P dari 26,54 menjadi 30,05%. Selanjutnya padatahun II, tambahan pengairan sampai kandungan air tanah 50% tidakmempengaruhi kandungan minyak biji IP-1A, IP-1M, dan IP-1P.Kata kunci: Jarak pagar, ketersediaan air tanah, pengairan, produksi biji,kandungan minyak bijiABSTRACTEffects of irrigation on seed production and oil content ofthree provenances of physic nut (Jatropha curcas L.)A field experiment was conducted at the experiment station ofIndonesian Tobacco and Fiber Crops Research Institute in Muktiharjo, Pation a soil texture of silty clay for three years from 2007 to 2009. Theexperiment aimed to investigate the response of irrigation on productionand oil content of jatropha seed. Jatropha was planted in February 2007.The experiment used a striped plot design with three replicates. Itconsisted of two factors, firstly three provenances : IP-1A, IP-1M, and IP-1P, and secondly four irrigation levels : control (no irrigation), irrigationwhen available soil water content reached 35, 50, and 65%. Irrigation wasapplied during the dry season. The first pruning was done in the secondyear during rainy season (September 2008). The results showed thatsupplementary irrigation was needed only in the first year. The productionof jatropha seeds was not affected by irrigation from the second year on.The plants did not require additional irrigation during the dry season andthey well adapted to different soil available water, especially in areas withannual rainfall of 1,200-1,500 mm. When no irrigation supply or underinsufficient moisture content, the seed yield of IP-1A and IP-1P decreasedby 37-59 and 17-31%. In the second and third years, seed production of allirrigation treatments ranged from 842-975 and about 818-966 kg/ha. IP-1Pproduced the highest seed yield (1,369 kg/ha) compared to IP-1A (737kg/ha) and IP-1M (631 kg/ha) second year. In the third year, seedproduction of IP-1P was 1,268 kg/ha which was still more superior thanIP-1A (902 kg/ha) and IP-1M (416 kg/ha). Compared to the other twoprovenances, IP-1P was higher ability in producing productive branchesand fruits. In addition to increase in seed production, supplementaryirrigation during the dry season in the first year also increased seed oilcontent from 27.26 to 29.89% for IP-1A and from 26.54 to 30.05% for IP-1P. Furthermore, in the second year an additional irrigation to soilavailable water of 50% did not affect the seed oil content of allprovenances.Key words: Jatropha curcas L., soil available water, irrigation, seedyield, seed oil content

Abstract

ABSTRAKTembakau Temanggung merupakan komoditas penting bahan bakuindustri rokok kretek, sumber pendapatan petani dan PAD KabupatenTemanggung. Selain itu, tembakau juga menjadi pemicu pertumbuhankegiatan ekonomi lainnya yang terkait dengan usahatani, sepertitransportasi, penyediaan sarana produksi pertanian serta penyediaanlapangan kerja. Usahatani tembakau Temanggung menghadapi 3 (tiga)masalah utama, yaitu: sifat tembakau Temanggung yang tergolong fancyproduct, struktur pasar yang monopsonistik dan kondisi lahan usahataniyang beragam (beragam menurut elevasi, arah lereng dan tingkatkemiringan lereng). Kondisi lahan tersebut mengakibatkan mutu tembakaumenjadi beragam, dan cenderung menurun bahkan mengancam keber-lanjutan usahatani tembakau. Penelitian ini dilaksanakan bulan Januari2004 - Maret 2005 di sentra produksi tembakau Temanggung, yangmemiliki beberapa perbedaan berdasarkan elevasi, arah lereng dan tingkatkemiringan. Untuk mengetahui ragam mutu dan produktivitas dianalisisdengan sidik ragam. Untuk mengetahui pengaruh elevasi, arah dankemiringan  lereng  digunakan  analisis  regresi  berganda.  Dalammenganalisis keberlanjutan usahatani, digunakan multi atribut non-parametrik yang diolah dengan multidimentional scaling (MDS). Mutu danproduktivitas tembakau Temanggung cukup beragam. Elevasi dan arahlereng (slope aspect) merupakan faktor utama yang mempengaruhi mutudan produktivitas tembakau Temanggung. Mutu tembakau yang ditanampada lahan berelevasi di atas 1.000 m dpl, nyata lebih baik dibandingkandengan mutu tembakau yang ditanam pada lahan yang berelevasi kurangdari 1.000 m dpl. Produktivitas tembakau yang ditanam pada lahan arahlereng ke timur nyata lebih tinggi dibandingkan dengan produktivitastembakau pada lahan arah lereng ke timur laut dan utara. Tingkatkemiringan lereng tidak berpengaruh terhadap mutu maupun produktivitastembakau. Indeks keberlanjutan usahatani tembakau Temanggung,termasuk kedalam kategori cukup (IKb = 55,53 pada skala keberlanjutan 0– 100).Kata kunci : Tembakau, Nicotiana tabacum L., tembakau Temanggung,mutu, produktivitas, indeks keberlanjutan, usahatani, JawaTengahABSTRACTAnalysis of quality, productivity and sustainability anddevelopment direction of tobacco farming in TemanggungDistrict, Central JavaTemanggung tobacco is an important commodity for cigaretteindustry, farmers’ income and product domestic regional brutto (PDRB)of Temanggung District. Tobacco stimulates economy activities, so that itcan grow other bussiness activities, such as transportation, agroproductand employment availability. Uncontrolled cultivation intensity andmarket structure monopsonistic resulted in weak bargaining position offarmer in marketing tobacco. Tobacco is a fancy product, it means that itsmarketing and transaction are very determined by quality. Theseconditions affected the sustainability of tobacco farm. This research wascarried out from January 2004 to March 2005 in the center of Temanggungtobacco production, which varies in terms of elevation, slope aspect andtopography. Temanggung tobacco varies in terms of quality andproductivity. Elevation and slope aspect were the primary factorsinfluencing tobacco productivity and quality. The quality of tobaccoplanted at farmer location at the elevation more than 1.000 m above sealevel (asl) with slope facing east, was significantly better than the qualityof tobacco planted at the elevation less than 1.000 m asl with slope facingnorth-east and north. The tobacco productivity planted on the slope facingeast differed significantly with the tobacco productivity planted on north-east and north slope facing. The slope did not significantly influencetobacco quality and productivity.

Abstract

The attack of Mimegralla coeruleifrons on ginger plants and its role in carrying pathogens of wilt diseaseRhizome flics Mimegralla coeruleifrons (Diplera; Micropezidae) ac frequently oten found in the diseased ginger rhizome caused by Ralstonia solanacearum, bill it has nol been known which one made the irst damage. Experiments were conducted at laboratory and green house of the Research Institute for Spice and Medicinal Cops from September 1998 to I'cbruary 2000. to examine the attack of M coerulefrons on healthy and disease ginger plants and its role in carrying the pauiogen. Hie experiments consisted of three parts, ink-station of the fly in healthy and diseased ginger plants, disease tansmission and detection of R solanacearum in M coeruleifrons larvae and adults, fiingcr plants were grown in pot containing, sterile media The pots were placed in the field and the plants were inoculated with R solanacearum and iininoculatcd. then they were caged or uncaged. Adult lies (33 - 35 pairs) were introduced into the cage. The uncaged plants were allowed to be naturally invested by the flies. Disease transmission used adult Hies which were collected from diseased ginger plantation. The lies were fed with suspension of R solanacearum. then introduced into cages containing healthy ginger plants. The flies were also directly caged on healthy plants Detection of/?, solanacearum in larvae and adults was carried out by isolation on selective medium and ELISA techniques. Results showed that M coerulefrons mostly attacked the inoculated ginger plants. Tliere was no evidence of Iransmission of R solanacearum by the fly. whereas nearly 50% of the ield collected lics carried R solanacearum. These results tend to suggest that the attack of M. coerulerons occured ater the ginger has been infected by wilt disease and the ly can be a carrier of/? solanacearum.

Penelitian ini dilakukan dalam tigatahap, yaitu : 1) respon tunas pada media perbanyakan, menguji mediamultiplikasi tunas dengan media sitokinin tunggal yaitu : MS + BenzilAdenin (BA) 0,5; 1,0; 1,5 dan 2,0 mg/l; tahap 2) respon tunas pada mediakombinasi sitokinin dan auksin, yaitu : MS + BA 0,5 mg/l + NAA 0,1mg/l; MS + BA 0,5 mg/l + NAA 0,5 mg/l; MS + BA 1,0 mg/l + NAA 0,1mg/l dan MS + BA 1,0 mg/l + NAA 0,5 mg/l. Tahap 3) Daya multiplikasidan penampilan tunas setelah subkultur pada media yang sama. Masingmasingpercobaan disusun dengan rancangan acak lengkap, dan terdiri atas5 ulangan. Parameter pengamatan meliputi jumlah tunas, tinggi tunas danjumlah ruas serta penampilan visual. Hasil penelitian menunjukkan bahwapada tahap pertama, penggunaan media MS + BA 0,5 menghasilkanjumlah tunas yang paling banyak dibandingkan yang lain, tetapi tidakberbeda nyata pada jumlah ruas dan tinggi eksplan. Sementara pada tahapdua, jumlah tunas terbaik didapat pada media dengan auksin rendah baikpada kombinasi sitokinin rendah dan tinggi. Sementara untuk jumlah ruasmedia terbaik adalah media dengan konsentrasi BA tinggi yangdikombinasi dengan NAA. Untuk tinggi tunas, media terbaik adalah MS +BA 1,0 mg/l + NAA 0,5 mg/l, tapi ditemukan eksplan yang menguning.Pada tahap ketiga, dari hasil subkultur kembali terlihat bahwa tunas yangbersumber dari pucuk pertumbuhannya baik sementara tunas yang berasaldari ruas ke-2 dan 3 sebagian menguning.Kata kunci : Ficus deltoidea Jack, tunas, induksi, in vitro, BA, NAAABSTRACTIn vitro shoot induction of Mistleteo fig (Ficus deltoideaJack) in Murashige & Skoog (MS) media with addition ofBA and NAAMistleteo fig (Ficus deltoidea) is one of endangered medicinalplants and used for female aphrodisiac. In vitro multiplication of the plantwas done to find a number of shoots. This experiment was conducted intissue culture laboratory of Germplasm and Breeding of IMACRI fromJanuary to December 2007, and aimed to find best media for shootmultiplication. This experiment was carried out in three steps: step 1)shoot respon in multiplication media using single cytokinin : MS + BA(0.5; 1.0; 1.5 and 2 mg/l); step 2) shoot respon in multiplication media ofcombined cytokinin and auxin : MS + BA 0.5 mg/l + NAA 0.1mg/l; MS+ BA 0.5 mg/l + NAA 0.5 mg/l; MS + BA 1.0 mg/l + NAA 0.1 mg/l andMS + BA 1.0 + NAA 0.5 mg/l; and step 3) viability and visualization ofthe shoots after subcultured in the same media. The experiment wasarranged using completely randomized design with 5 replicates. Theparameters observed were of shoots and nodes, shoot height andperformance. The results in the first step showed that MS + BA 0.5 mg/lmedia resulted in the highest number of shoots, but they were notsignificantly different in the number of nodes and shoots height. In thesecond step, highest number of shoots was found using low concentrationof auxin combined with low and high concentration of cytokinin. Bestmedium for number of nodes was MS with high concentration of BAcombined with NAA. For shoot height, the best medium was MS + BA0.1 mg/l + NAA 0.5 mg/l, but the shoots turned yellow. In the third step,after subcultured, the shoots originated from plant tips performed well,however, those taken from second and third inter nodes partially turnedyellow.Key words : Ficus deltoidea Jack, shoot, induction, in vitro, BA, NAA

Penelitian menggunakantanaman yang tidak berbunga akibat panjang hari normal dan tanamanberbunga akibat penambahan cahaya empat jam, pukul 18.00-22.00 mulaiumur 30 hari. Penelitian menggunakan rancangan acak kelompok 5perlakuan, yaitu B 0 (tanaman berbunga dibiarkan), B 1 (tanaman berbungadipotong bunganya), B 2 (tanaman berbunga diletakkan pada kondisinormal), B 3  (tanaman tidak berbunga dibiarkan), dan B 4 (tanaman tidakberbunga dipotong pucuk). Hasil penelitian menunjukkan bahwapemotongan bunga meningkatkan mentol dan menekan menthofuran.Penghentian penambahan cahaya 4 jam pada tanaman berbungamenjadikan tanaman merunduk, kadar mentol menurun dan menthofuranmeningkat. Pemotongan pucuk dapat menurunkan kandungan mentol danmeningkatkan kandungan menthofuran.Kata kunci : Mentha, Mentha piperita L., pemotongan bunga, pucuk,pencahayaan, kandungan mentol, kandungan menthofuranABSTRACTThe effect of inflorescent pinching , bud pinching, andnormal light period on peppermint (Mentha piperita L)Experiment on the effect of pinching the inflorescent, pinching thebud, and normal light period on peppermint (Mentha piperita L) wascarried out at the experimental garden Lembang of Research Institute forSpice and Medicinal Crops, West Java, from January to July, 2000. Thestudy was conducted with two steps i.e. The first step was manipulation ofphoto period using TL lamps and the second step was distillation andanalisis of peppermint oil from their products with gas chromatographyand mass spectrometry. The experiment, 5 treatments were given i.e.using long day treated plants, 3 treatments are given i.e. control, pinchingthe inflorescent and with holding light supplement (four hours lightsupplement at the age of 30 days), and using control plants, 2 treamentsare given i.e. no pinching and pinching of terminal bud (control or normallight period). The result showed that pinching the inflorescent elevate thementhol and reduce the menthofuran content. Pinching the bud of nonflowering plants can reduce the menthol and increase the menthofurancontent.Key words : Peppermint, Mentha piperita L, inflorescent pinching, bud,pinching, light period, menthol content, menthofuran content

Abstract

AbstrakMinyak kelapa murni (Virgin Coconut Oil/VCO), yang komponen utamanya adalah asam lemak rantai medium (ALRM) bermanfaat untuk bayi, sehingga perlu dimanfaatkan pada pengolahan biskuit dengan penambahan minyak kedelai (MKD) sebagai sumber asam lemak esensial. Penelitian dilaksanakan di Balit Palma dan Laboratorium Teknologi Hasil UGM-Yogyakarta pada tahun 2010. Tujuan penelitian mempelajari karakteristik biskuit yang disubstitusi VCO dan MKD serta mengetahui mutu secara in vivo menggunakan tikus sebagai hewan uji. Penelitian menggunakan Rancangan Acak Lengkap (RAL), dengan 7 perlakuan perbandingan VCO dan MKD, yaitu (1) Formula A=VCO : MKD = 12 : 5 ; (2) B=VCO : MKD = 13 : 4 ; (3) C=VCO : MKD = 14 : 3 ; (4) D=VCO : MKD = 15 : 2 ; (5) E=VCO : MKD = 16 : 1 ; (6) F=VCO : MKD = 17 : 0 ; (7) G=kontrol. Hasil analisis enam formula biskuit yang ditambah VCO, kadar air 4,16-4,76%, lemak 25,12-28,54%, protein 12,92-14,53%, abu 0,69-0,82%, karbohidrat 51,55-56,66%, dan kalori 467-520 kkal. Jumlah ALRM Formula A, B, C, D, E, dan F berturut-turut 10,19; 9,42; 11,51; 11,29; 14,58; dan 16,83%. Komposisi asam lemak linoleat berturut-turut 1,71; 1,76; 1,73; 1,75; 1,28; dan 0,01%. Kenaikan berat badan tikus tertinggi yang mengonsumsi formula dengan penambahan VCO adalah Formula A (6,33%) dan terendah Formula F (2,54%). Demikian juga Protein Efisiensi Ratio (PER) tertinggi Formula A (4,39) dan terendah Formula F (2,06). Berdasarkan jumlah ALRM dikaitkan dengan asam lemak esensial linoleat dan PER, formula terbaik berturut-turut adalah A, B, C dan D.Kata kunci: VCO, formula biskuit, asam lemak

Abstract

The contribution of estate subsector to the income of the farmers living in the forest and in the ■urronding area is still low. This study was caried out socioeconomic and their roles in improving their welfare. The study was conducted rom August to October 2000 in three forest management systems (1) system of Hak Pengusahaan Hutan (HPH) which was represented by Sukamulya and Siabu villages, Bangkinang, Kampar District, and Rambah Jaya Village, Rambah Hilir, Rokan Hulu District; (2) System of Hutan Taman Nasional which was represented by Andongrejo and Eaat Java Province; (3) System of Hutan Sosial (Perum Perhutani) which waa represented by Kedung Urang Village, Cilacap Subdistrict, and Sawangan Village, Jeruk Legi Subdistrict, Cilacap District, Central Java Province. Sample villages were chosen through purpose sampling method. The data were analyzed desciptively and comparative and approacted through socioeconomic indicators and criteria. The results of the research indicated that the socioeconomic condition of the estate farmers living in the forest and in the surrounding are was lower compared to those of the area was lower compared to those of the rice farmers and others farmers. The average income of the estate farmers ranged between Rp 360 860.00 and Rp 523 550.00. The range of income distribution (Gini ratio) was 0.295 to 0.430. Out of the three forest mana¬ gement systems, the village of Hutan Taman Nasional was better than those of two other systems, where the income level waa Rp 432 000.00 Gini ratio was 0.320; structure and inrastucture was moderate.
