Kuantitas endospermakelapa Genjah kopyor asal Pati bervariasi antara skor 1–6. Keragamangenetik yang rendah dalam varietas dan tinggi antar ketiga varietas (coklat,hijau, dan kuning) memperkuat pelepasan ketiganya sebagai varietas lokal.Selain itu, keragaman genetik antar tanaman dalam varietas yang rendahmendukung penggunaan ketiga varietas lokal sebagai tetua dalam programperakitan varietas kelapa kopyor unggul baru. Tetua yang dipilih dapatdiseleksi intra-varietas berdasarkan persentase buah kopyor per tandandan skor kuantitas endosperma yang tinggi.Kata kunci: Keragaman morfologis, keragaman intra dan antar varietas,kuantitas endospermaABSTRACTKopyor dwarf coconuts are mutants from Pati, Central Java havinghigh economic values. However, morphological and genetic diversities ofthis coconut were still limited. Morphological and genetic diversity dataare needed for breeding program. The research objectives were to evaluateintra and inter-specific diversity based on morphology, endospermquantity, and SSR alleles. Field evaluations were conducted in Pati whilelaboratory activities were at Plant Molecular Biology Laboratory,Department of Agronomy and Horticulture, IPB. Three populations ofkopyor dwarf varieties (brown, green, and yellow) were evaluated. Thirtytrees were sampled for each population. The average of morphologicaldata were used to construct cluster analysis. Endosperm quantity wasscored (0 – 9) based on a single nut sample. Ten palms were analyzedusing five SSR loci for each population and used to determine geneticdiversity of populations. Results of observations indicated intra-varietymorphological and SSR allele variations among kopyor dwarf was low.However, inter-variety variations were high. The endosperm quantityscores among kopyor dwarf coconut ranged from 1–6. The low intra-variety and high inter-variety variations among the three kopyor dwarfcoconut supported their release as different local varieties. Moreover, thelow intra-variety phenotypic and genotypic diversities among kopyorbrown, green, and yellow dwarf coconut support their use as parents fornew and superior kopyor coconut variety development in the future. Forsuch purpose, however, it is necessary to conduct intra-variety selection toidentify desirable parents based on high kopyor fruit percentage per bunchand for high kopyor endosperm quantity.Key words: Morphological diversity, intra and inter variety diversities,quantity, endosperm

Tujuan penelitian adalah untuk meningkatkan keragaman genetik lada varietas Petaling 1 menggunakan mutagen kimia kolkhisin. Biji lada direndam dalam larutan kolkhisin konsentrasi 0; 0,01; 0,03; dan 0,05% selama 4 jam dan disemai pada bak pasir. Masing-masing perlakuan diulang 3 kali  dan  setiap ulangan  terdiri atas 300 biji.  Pengamatan dilakukan  terhadap  persentase  perkecambahan  dan  fenotipe  tanaman, persentase tumbuh, tinggi tanaman, serta jumlah ruas dan daun pada umur dua bulan. Selanjutnya, sebanyak 20 individu dari total benih yang tumbuh dipilih berdasarkan rata rata penggabungan dari tanaman terpendek dan tertinggi. Individu terpilih diamati tinggi tanaman serta jumlah ruas dan daun pada umur empat bulan. Untuk melihat ragam genetik dilakukan analisis kandungan DNA dengan flowcytometry. Hasil penelitian menunjukkan bahwa perlakuan kolkhisin 0,01 dan 0,05% menghasilkan persentase perkecambahan benih di persemaian lebih tinggi. Pada lada mutan  vegetatif generasi  ke-0,  perubahan  morfologi  terindikasi  pada konsentrasi 0,03%.  Pada  generasi  mutan hasil  perbanyakan/turunan vegetatif pertama  perubahan  morfologi  pada  tanaman terjadi  pada perlakuan 0,05%. Namun, tidak ada perbedaan yang nyata pada tingkat ploidi lada pada semua perlakuan termasuk kontrol.Kata kunci:  Piper nigrum L., ragam genetik, mutan, kolkhisin, fenotip ABSTRACTEffect of Colchicine on the Phenothypic Performance of Pepper (Piper nigrum L.) Mutant and Ploidy analysisGenetic variability of pepper (Piper nigrum) in Indonesia was low, so it was needed to increase its variability. Research was conducted at the green house of Indonesian Spices and Medicinal Crops Research Institute, Bogor from January 2012 to June 2013. The aim of the research was to increase the genetic variability of pepper (Petaling 1) using chemical mutagen colchicine. Seeds of pepper were soaked in colchicine solution with several concentration (0; 0,01; 0,03; and 0,05%) for four hours, and then germinated on sand media. Every treatment consisted of 300 seeds and replicated three times. The parameter observed were germination percentage, plant phenotype, growth percentage, plant hight, number of node and leaves two months after planting. Further, from total seedling growth, 20 individual were selected based on average combined from highest and shortest plant. The selected individual observed their plant height, number of node and leaves on four months. Flowcytometri analysis from  the  selected  seedling  was  conducted to  find  interplant  genetic variabilities. The result showed that application of colchicin 0,01 and 0,05% performed the fast germination on the nursery compared with control, but no significant differencet on the growth parameters. In the mutant generation 0, the changes on morphology showed on 0,03% and at the first vegetative generation, the changes were indicated in plants from  0,05%  of  colchicine  treatment.  Flowcytometri  analysis  showed  no  significant differences on ploidi level of all treatments including control.Keywords:   Piper   nigrum,   genetic   variability,   mutant,  cholchicin, phenotype

Abstract

The role and potency of natural enemies in controlling HeUcoverpa armigera Hubner in cottonHeUcoverpa armigera. known as the cotton bollworm, is one of cotton productivity limiting factors. Efforts in controlling this pesl have been directed lo (he use of its natural enemies, viz. parasiloids. predator and insect pathogens in conservation techniques The study was conducted in two activities. The irst activity was the inventory of parasiloids and predators of// armigera. which was conducted from 1986 to 1999 in the cotton development area in Central Java (Rembang, Pati, and Grobogan).  East Java (Situbondo, Banyuwangi, Tuban. and Lanongan), NIB (Menangabaris. Lokopriya, and Sandubaya), and NTF (Maumere, Wailiti. and Larantuka). The second activity was to sludy the potency of dominant parasiloids and predators in cotton, which was conducted in 1999/2000 in the Research Instalaiion for Tobacco and Fibre Crops, Asembagus. The objectives of the study were to evaluate Ihe diversity of natural enemies, particularly parasiloids and predators, and their role in controlling Ihe population of // armigera in cotton. The inventory of parasiloids and predators was conducted to 15 and 21 species, respectively. The predominant parasiloids were Trichogramma-loidea armigera Nagaraja (egg parasitoid) and Eriborus argenteopilosus Camreon (larval parasitoid). The predominant predators were Deraeocoris indianus Carvalho, Campylomma diversicornis Rcuter (Hemiptera Miridae). Paederus fasciatus Curtis (Coleoptera Staphylinidac) and Coccinellid beetles (Coleoptera Coccincllidac). These predators feed on eggs and small larvae of //. armigera. The potency of these parasiloids and predator, as mortality factors of the pesl, was quantitatively studied in insecticide sprayed and unsprayed cotton ields. The egg and larval parasiloids caused mortality of //. armigera eggs and larvae as high as 65% and 21%, respectively. The predators suppressed // armigera population by 82%, so that its population was lower than that of the plots treated with insecticide. These suppressions resulted in a significantly lower damage of cotton fruiting bodies (4.3-8.0% on sprayed plots vs.1.7-3.4% on unsprayed plots) and hence, a signiicantly higher production of seed cotton ( I 838 kg/ha on sprayed plots vs. 2 170 kg/ha on unsprayed plots). Thereore, // armigera population on collon basically could be managed by its natural enemies below its action threshold, when Hie natural enemies were allowed to build up their population.

Abstract

The physical and chemical properties of the growing medium for root trainer of rubber are critical to support plant growth. This study aimed to obtain the best medium for growing rootstock rubber seedlings in the root trainer.  Rubber clone PR 300 seeds were germinated for 21 days, then raised in root trainer pots for five months. The treatments evaluated were a mixture of cocopeat, Rawapening peat, and manure at different ratios.  The experiment was designed in a Randomized Block Design, three replications, 30 plants per replicate, totaling 720 plants. The observed variables were N, P, K, Mg, C-organic content, pH, and cation exchange capacity of cocopeat, peat, and manure, as well as plant growth (height, stem diameter, wet weight, and dry weight). ANOVA used for analyzing data, followed with the Duncan Multiple Range Test at 5% level. The results showed that there were three best root trainer media for PR 300 rubber rootstock seedlings were a mixture of cocopeat + peat (1:1), cocopeat + peat + manure (1:2:1), and cocopeat + peat + manure (2:1:1). The growth and compactness of the roots are outstanding, so the seedlings are easily removed from the root trainer pots without significant damage. Based on the initiation and cost, the best root trainer medium is a mixture of cocopeat + peat + manure (1: 2:1). It is necessary to study the use of other types of peat soils apart from Rawapening. Also, it needs to be observed further plant growth after inoculation with the stem and after planting in the field.Keywords : Planting medium, Rawapening peat, rubber clone PR 300.

Abstract

Rearing of Helopeltis antonii Sign (Hemiptera; Miridae) on cucumberfruit and cashew shootHelopeltis antonii is well known as a major pest of cashew, cacao and tea plantations A suficient number of the insect is frequently needed for esearch purposes. Rearing of // antonii on cucumber fruit was conducted from October 1997 to May 1998. Under laboratory condition. total eggs layed were 3.2 per female per day, while female longivity was 18.9 days. Egg period was 6.1 days and the total hatched was 93.5 percent. The egg and the irst unlil the ifth instar nymph periods were 6.1; 2.3; 2.0; 1.8; 1.9 and 3.2 days espectively. The adults emerged from earing of 10, 20 and 30 newly hatched nymph were 7. 13. and 17 insects or 71.3; 65.0, and 58.0 percent respectively. Eggs and nymph periods on cashew shoot almost the same as on cucumber fruit. The hatched eggs on cutted cashew shoot was 12 percent, while on the shoot of cashew seedlings was 89.0 percent This study indicated that cucumber fruit is very suitable and easier as well as more economical for mass rearing of // antonii.

Abstract

ABSTRAKIndonesia terkenal kaya akan keanekaragaman hayati, termasukjenis tumbuhan yang mengandung bahan aktif insektisida. Tanamankamandrah (Croton tiglium L.) merupakan salah satu tanaman obat yangbanyak terdapat di wilayah Indonesia dan telah dimanfaatkan sebagaiinsektisida nabati. Penelitian ini bertujuan untuk mengetahui karakteristikfisiko-kimia minyak kamandrah pada berbagai tingkat kematangan sebagailarvasida nabati terhadap larva nyamuk demam berdarah dengue (A.aegypti). Penelitian dilakukan di Laboratorium Balai Penelitian TanamanRempah dan Aneka Tanaman Industri (Balittri) Sukabumi, Balai BesarLitbang  Pascapanen  Pertanian  Bogor,  Insektarium  LaboratoriumParasitologi dan Entomologi Kesehatan FKH IPB Bogor, dan Biofarmaka-LPPM IPB Bogor, mulai bulan Februari sampai Desember 2010. Minyakkamandrah diperoleh dengan ekstraksi menggunakan pengempa hidrolikpada suhu 65 o C dan tekanan 7,9 MPa pada buah kamandrah dengan tigatingkat kematangan yang berbeda: warna kulit buah hijau kecokelatan,cokelat kehijauan, dan cokelat penuh. Minyak yang diperoleh selanjutnyadianalisis bilangan asam, kadar asam lemak bebas, bilangan peroksida,indeks bias, berat jenis, dan nilai warna minyak, serta uji larvasidaterhadap larva nyamuk A. aegypti instar III. Penentuan nilai lethalconcentration (LC) dilakukan dengan metode probit analisis (FinneyMethod). Hasil penelitian menunjukkan bahwa berdasarkan nilai LC,rendemen, dan mutu minyaknya, buah kamandrah yang berwarna kulitcokelat penuh lebih berpotensi sebagai larvasida nabati terhadap larva A.aegypti. Rendemen minyak kamandrah 20,42% dan nilai LC 50 adalah132,67 ppm (24 jam) dan 70,08 ppm (48 jam). Minyak tersebut memilikibilangan asam 8,76 mg KOH/g minyak; kadar asam lemak bebas 4,36 mgKOH/g minyak; bilangan peroksida 3,59 meq O/100g minyak; indeks bias1,4783; bobot jenis 0,9466 g/ml; dan warna meliputi nilai L* 73,03; a*3,26; dan b* 64,13. Minyak kamandrah berpotensi dapat dimanfaatkansebagai larvasida nabati dalam pengendalian vektor penyakit DBD.Kata kunci : Croton tiglium L., kematangan buah, minyak kamandrah,larvasidaABSTRACTEffect of Maturity Level of Fruits on Larvicidal Activityand Physico-Chemical Properties of Kamandrah (Crotontiglium L.) OilIndonesia is famously rich in biodiversity, including species of plants thatcontain active ingredient for insecticide. Kamandrah plant (Croton tigliumL.) is one of many medicinal plants found in parts of Indonesia and it hasbeen used as an insecticidal plant. The objectives this research were todetermine the physico-chemical characteristics and larvasidal activities ofoil extracted from kamandrah seeds with varying levels of maturity asbotanical larvicide for mosquito dengue fever. The expreriments wereconducted in the Laboratory of Indonesian Spice and Industrial CropsResearch Institute (ISICRI) Sukabumi, Indonesian Center for AgriculturalPostharvest Research  and  Development (ICAPRD),  InsectariumLaboratory of Health Parasitology and Entomology, Faculty of Veterinaryof Bogor Agricultural University (IPB), and Biopharmaca IPB Bogor,from February to December 2010. The oil was obtained through extractionusing hydraulic pressurer at 65 o C temperatures and 7.9 MPa pressures ofkamandrah fruits with three different maturity levels : brownish green,greenish brown, and fully brown color of fruit skins. Oil gained was thenanalyzed its acid number, free fatty acid content, peroxides number,refractive index, specific gravity, and oil color values, as well as the oillarvasida test against mosquito larvae A. aegypti instar III. Determinationthe oil lethal concentration (LC) values was tested using probit analysismethod (Finney Method). The results showed that based on the values ofLC, content, and quality of the oil, full-brown colored kamandrah fruits aremore potential as larvivida against A. aegypti larvae. Oil content of thekamandrah was 20.42% while LC 50 values were 132.67 ppm (at 24 hours)and 70.08 ppm (at 48 hours). The acid number of the oil was 8.76 mgKOH/g oil; free fatty acid level of 4.36 mg KOH/g oil; peroxide number of3.59 meq O/100 g oil, refractive index of 1.4783; density of 0.9466 g/ml;and the color values were 73.03, 3.26, and 64.13 for L*, a*, and b*,respectively. Therefore, kamandrah oil is very potential to be used aslarvicide for controling the vector of dengue disease.Key words: Croton tiglium L., fruit maturity, kamandrah oil, larvicide
