Field Efficacy

The extract of Nicotiana tabacum L. var Virginia origin of Ponorogo (EHRE-Nt) was applied under field conditions against the coffee borer beetle Hypothenemus hampei (CBB). Three extract formulations containing 150, 300, and 450 ml of EHRE-Nt in 100 liters of water were prepared and sprayed on 0.5 hectares each. A nontreatment was applied as a control on 0.5 hectares of plantation. The intensity of the CBB attacks was observed for six weeks on a Robusta coffee plantation in the Kalibening area, South Semarang, Central Java, Indonesia. An extract formulation containing 450 ml of EHRE-Nt resulted in the lowest intensity of CBB attacks from weeks one to six (1.6% to 2.2%). The attacks of the control field were 11.3% to 13.5%. The highest efficacy level of 85.4% was obtained with the 450 ml EHRE-Nt formulation. These results demonstrate that EHRE-Nt has potential as a bioinsecticide for coffee berries from CBB attacks.

Tobacco (Nicotiana tabacum L.) is a plant used as a mixture of cigarettes, and recreational media especially for men. This study aimed to identify variations, and determine the relationship between tobacco cultivars in Central Java and Yogyakarta based on macromorphological and micromorphological characters. Sampling locations are determined by surveying locations in both regions. Tobacco samples found include 5 cultivars in Central Java namely 'Mantili', 'Uler Magetan', 'Garut', ‘Gober Boyolali’, 'Manila', and 3 cultivars in Yogyakarta namely 'Siluk', 'Java', and 'Virginia'. Characterization with 23 qualitative macromorphological characters including leaves, and stems, with 9 qualitative and quantitative micromorphological characters including trichome and stomata. Descriptive data analysis is done to obtain the typical character of each cultivar, followed by numerical analysis including scoring characters processed with MVSP (Multi Variate Statistical Package), clustering with UPGMA (Unweighted Pair Group Method with Averages), and calculation of similarity coefficients with Simple matching formula. The results showed variations in the macromorphological characters including the shape of the leaf lamina, the base of the leaf, the absence of leaf stalks, and type of leaf venation. Tobacco has anisositic stomata, and varies in terms of length, width, and density of stomata. Tobacco trichomes are glandular. The result dendrograms form two clusters (A and B) with the similarity index of each cluster above 0.80. Cultivars with close relationships such as 'Siluk'-'Java', and far relationship like 'Java'-'Manila'.

ABSTRACTCoffee Fruit Borer (CFB) (Hypothenemus hampeii) is an important pest that attacks the coffee fruit in coffee plantation. However, farmers have difficulty getting attractant, then need to look for alternative attractant derived from natural ingredients that exist around the farm, one of them such as chlorogenic acid compounds that exist in the coffee fruit. This research was conducted at 4 locations (2 sites in Sidikalang and 2 sites in Sumbul sub district with 5 stations and 5 treatments) used a randomized block design with 5 treatments, that are K0 (Control), K1 (25 ml chlorogenic acid compound), K2 (50 ml chlorogenic acid compound), K3 (75 ml chlorogenic acid compound), K4 (100 ml chlorogenic acid compound). The trap uses a perforated aqua bottle and is hung on twigs at a height of 1.2 m. The results showed that the highest CFB collection from SiR2K2 at Sidikalang location on Robusta coffee with 50 ml of chlorogenic acid by 53 individuals, meanwhile the lowest CBF trapped is control treatment at Sumbul location on Robusta coffee type (SuR4K0) by 14 individuals And treatment (SuR3K4) at Sumbul location with Robusta and 100 ml of chlorogenic acid was the best treatment to reduce the percentage of CFB attack. The percentage of CFB attack with air humidity shows significance at F=0,018, p <0.05 and air temperature with F = 0,030, p, 0.05, where both of these factors greatly influence the percentage of PBKo attack. While Pearson Correlation value analysis between moisture and percentage of attack that is                  r = 1,000*, show the higher of moisture hence will be higher percentage of attack. CFB control measures are carried out by catching female flying insects using a pulling compound (attractant) so that the population of CFB in the coffee plantation will be reduced. Keywords: Attractant, Chlorogenic Acid, Hypothenemus hampeii, Coffee Plantation, Dairi  ABSTRAKPenggerek Buah Kopi (PBKo) (Hypothenemus hampei) merupakan hama penting yang menyerang buah kopi. Akan tetapi petani kesulitan mendapatkan atraktan, untuk itu perlu dicari atraktan alternatif yang berasal dari bahan-bahan nabati alami yang ada disekitar petani salah satunya seperti senyawa asam klorogenat yang ada pada buah kopi. Penelitian ini dilakukan di 4 lokasi perkebunan kopi masyarakat dimana 2 lokasi berada di Kecamatan Sidikalang dan 2 lokasi lainnya berada di Kecamatan Sumbul, Kabupaten Dairi, Sumatera Utara. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 5 perlakuan yaitu K0 (Kontrol), K1 (Senyawa asam klorogenat 25 ml),  K2 (Senyawa asam klorogenat 50 ml), K3 (Senyawa asam klorogenat 75 ml), K4 (Senyawa asam klorogenat 100 ml). Tiap lokasi terdiri dari 5 unit dan tiap unit terdiri dari 5 perlakuan. Perangkap menggunakan botol aqua yang dilubangi dan digantung pada ranting pada ketinggian 1,2 m. Hasil penelitian menunjukkan perlakuan (SiR2K2) yaitu pada lokasi Sidikalang pada jenis kopi Robusta dengan asam klorogenat sebanyak 50 ml merupakan perlakuan terbaik dalam meningkatkan jumlah PBKo terperangkap yaitu dengan rataan 8,83 individu, sedangkan perlakuan (SuR3K4) pada lokasi Sumbul dengan jenis kopi Robusta dan penggunaan atraktan asam klorogenat sebanyak 100 ml merupakan perlakuan terbaik dalam menekan persentase serangan PBKo. Persentase serangan CFB dengan kelembaban udara menunjukkan signifikansi pada nilai F= 0,018, p<0.05 dan suhu udara dengan nilai F= 0,030, p,0.05, dimana kedua faktor tersebut sangat mempengaruhi persentase serangan PBKo. Sedangkan analisis nilai Pearson Correlation antara kelembaban dan persentase serangan yaitu r= 1,000*,menunjukkan semakin tinggi kelembaban maka akan semakin tinggi persentase serangan. Upaya pengendalian PBKo dilakukan dengan cara menangkap serangga betina yang terbang menggunakan senyawa penarik (atraktan) sehingga populasi PBKo di pertanaman  kopi akan berkurang. Kata Kunci : Atraktan, Asam Klorogenat, Hypothenemus Hampei, Perkebunan Kopi, Dairi.

Experiments were conducted to study the NO3− and Cl− interactions during uptake by burley tobacco (Nicotiana tabacum L., cult Ky 14) and the effects of their interactions on plant composition over long growth periods. Results indicated that NO3− or Cl− inhibited the absorption of the other anion by burley tobacco plants but did not influence the composition of cations. Positive linear relationships were found between NO3− and Cl− levels in solution, and the NO3− and Cl− contents in the plants in the laboratory and greenhouse studies. The inhibition of NO3− by Cl− during accumulation was also evident for tobacco plants grown under field conditions for longer periods. The interaction between NO3− and Cl− appears to be competitive during accumulation by burley tobacco. Competition between NO3− and Cl− during accumulation is proposed to be localized in the leaf cell rather than at the root–media interface.

ABSTRAK<br />Tembakau Temanggung merupakan komoditas penting bahan baku<br />industri rokok kretek, sumber pendapatan petani dan PAD Kabupaten<br />Temanggung. Selain itu, tembakau juga menjadi pemicu pertumbuhan<br />kegiatan ekonomi lainnya yang terkait dengan usahatani, seperti<br />transportasi, penyediaan sarana produksi pertanian serta penyediaan<br />lapangan kerja. Usahatani tembakau Temanggung menghadapi 3 (tiga)<br />masalah utama, yaitu: sifat tembakau Temanggung yang tergolong fancy<br />product, struktur pasar yang monopsonistik dan kondisi lahan usahatani<br />yang beragam (beragam menurut elevasi, arah lereng dan tingkat<br />kemiringan lereng). Kondisi lahan tersebut mengakibatkan mutu tembakau<br />menjadi beragam, dan cenderung menurun bahkan mengancam keber-<br />lanjutan usahatani tembakau. Penelitian ini dilaksanakan bulan Januari<br />2004 - Maret 2005 di sentra produksi tembakau Temanggung, yang<br />memiliki beberapa perbedaan berdasarkan elevasi, arah lereng dan tingkat<br />kemiringan. Untuk mengetahui ragam mutu dan produktivitas dianalisis<br />dengan sidik ragam. Untuk mengetahui pengaruh elevasi, arah dan<br />kemiringan  lereng  digunakan  analisis  regresi  berganda.  Dalam<br />menganalisis keberlanjutan usahatani, digunakan multi atribut non-<br />parametrik yang diolah dengan multidimentional scaling (MDS). Mutu dan<br />produktivitas tembakau Temanggung cukup beragam. Elevasi dan arah<br />lereng (slope aspect) merupakan faktor utama yang mempengaruhi mutu<br />dan produktivitas tembakau Temanggung. Mutu tembakau yang ditanam<br />pada lahan berelevasi di atas 1.000 m dpl, nyata lebih baik dibandingkan<br />dengan mutu tembakau yang ditanam pada lahan yang berelevasi kurang<br />dari 1.000 m dpl. Produktivitas tembakau yang ditanam pada lahan arah<br />lereng ke timur nyata lebih tinggi dibandingkan dengan produktivitas<br />tembakau pada lahan arah lereng ke timur laut dan utara. Tingkat<br />kemiringan lereng tidak berpengaruh terhadap mutu maupun produktivitas<br />tembakau. Indeks keberlanjutan usahatani tembakau Temanggung,<br />termasuk kedalam kategori cukup (IKb = 55,53 pada skala keberlanjutan 0<br />– 100).<br />Kata kunci : Tembakau, Nicotiana tabacum L., tembakau Temanggung,<br />mutu, produktivitas, indeks keberlanjutan, usahatani, Jawa<br />Tengah<br />ABSTRACT<br />Analysis of quality, productivity and sustainability and<br />development direction of tobacco farming in Temanggung<br />District, Central Java<br />Temanggung tobacco is an important commodity for cigarette<br />industry, farmers’ income and product domestic regional brutto (PDRB)<br />of Temanggung District. Tobacco stimulates economy activities, so that it<br />can grow other bussiness activities, such as transportation, agroproduct<br />and employment availability. Uncontrolled cultivation intensity and<br />market structure monopsonistic resulted in weak bargaining position of<br />farmer in marketing tobacco. Tobacco is a fancy product, it means that its<br />marketing and transaction are very determined by quality. These<br />conditions affected the sustainability of tobacco farm. This research was<br />carried out from January 2004 to March 2005 in the center of Temanggung<br />tobacco production, which varies in terms of elevation, slope aspect and<br />topography. Temanggung tobacco varies in terms of quality and<br />productivity. Elevation and slope aspect were the primary factors<br />influencing tobacco productivity and quality. The quality of tobacco<br />planted at farmer location at the elevation more than 1.000 m above sea<br />level (asl) with slope facing east, was significantly better than the quality<br />of tobacco planted at the elevation less than 1.000 m asl with slope facing<br />north-east and north. The tobacco productivity planted on the slope facing<br />east differed significantly with the tobacco productivity planted on north-<br />east and north slope facing. The slope did not significantly influence<br />tobacco quality and productivity. Sustainability index of tobacco farm<br />belongs to enough category (IKb = 55.53 at scale of sustainability 0 –<br />100).<br />Key words : Nicotiana tabacum L. Temanggung tobacco, quality,<br />productivity, sustainability index, farming system, Central<br />Java
