Abstract

ABSTRACTKetahanan tanaman terhadap serangga hama berdasarkan karaktermorfologi bulu (trichom) pada daun merupakan salah satu cara potensialmengurangi penggunaan insektisida kimia dalam pengendalian hama.Serangga hama pengisap Bemisia tabaci pada tanaman kapas juga dapatdikendalikan dengan menggunakan varietas kapas resisten berdasarkankarakter morfologi bulu daun. Penelitian peranan kerapatan bulu daunpada tanaman kapas terhadap kolonisasi B. tabaci Gennadius dilakukan diKebun Percobaan Pasirian, Kabupaten Lumajang, dan di LaboratoriumEntomologi Balai Penelitian Tanaman Tembakau dan Serat Malang, mulaiApril hingga Juli 2005. Tujuan penelitian adalah untuk mengetahuiperanan kerapatan bulu daun pada beberapa aksesi plasma nutfah kapasterhadap kolonisasi B. tabaci. Perlakuan terdiri atas 11 aksesi plasmanutfah kapas yang dipilih berdasarkan penilaian visual pada karakterkerapatan bulu daun yang mewakili kerapatan bulu rendah hingga tinggi,yaitu: (1) KK-3 (KI 638), (2) Kanesia 1 (KI 436), (3) A/35 Reba P 279 (KI257), (4) Acala 1517 (KI 174), (5) Asembagus 5/A/1 (KI 162), (6) 619-998xLGS-10-77-3-1 (KI 76), (7) DP Acala 90 (KI 23), (8) TAMCOT SP21 (KI 6)), (9) Kanesia 8 (KI 677), (10) CTX-8 (KI 494), dan (11) CTX-1(KI 487). Penelitian disusun dalam rancangan acak lengkap (RAL) dengan10 ulangan. Paramater yang diamati adalah jumlah bulu daun, telur dannimfa pada 1 cm2 luas daun, serta jumlah imago B. tabaci pada daunketiga dari atas tanaman. Hasil penelitian menunjukkan bahwa kerapatanbulu daun berkorelasi positif dengan kolonisasi B. tabaci (R=0,9701).Semakin tinggi kerapatan bulu daun, semakin meningkat kolonisasi B.tabaci. Kolonisasi B. tabaci lebih tinggi pada CTX-1, CTX-8, Kanesia 8,dan KK-3 (150-250 individu/cm 2 luas daun) karena tingkat kerapatan buludaun juga lebih tinggi (150-300 helai/cm 2 luas daun) dibanding TAMCOTSP 21, DP Acala 90, 619-998xLGS-10-77-3-1, Asembagus 5/A/1, Acala1517, A/35 Reba P 279, dan Kanesia 1 yang memiliki kerapatan bulu daun(0-100 helai/cm 2 luas daun) dan tingkat kolonisasi B. tabaci (<100individu/cm 2 luas daun) lebih rendah.Kata kunci : Kapas, Gossypium hirsutum, plasma nutfah, hama, Bemisiatabaci, trichom, kolonisasi, Jawa TimurABSTRACTRole of trichome density of cotton leaf to colonization ofBemisia tabaci GennadiusTrichome-based host plant resistance offers the potential to reducechemical insecticides used in insect pest control. Cotton whitefly, Bemisiatabaci can be controlled by using resistant variety based on trichomedensity as plant morphological characteristics. The study on the role oftrichome density of cotton accessions on the colonization of B. tabaci wascarried out at Pasirian Experimental Station at Lumajang, and atEntomology Laboratory of Indonesian Tobacco and Fiber Crops ResearchInstitute (IToFCRI ) in Malang from April to July 2005. Treatmentsincluded 11 cotton accessions, viz. (1) KK-3 (KI 638), (2) Kanesia 1 (KI436), (3) A/35 Reba P 279 (KI 257), (4) Acala 1517 (KI 174), (5)Asembagus 5/A/1 (KI 162), (6) 619-998xLGS-10-77-3-1 (KI 76), (7) DPAcala 90 (KI 23), (8) TAMCOT SP 21 (KI 6)), (9) Kanesia 8 (KI 677),(10) CTX-8 (KI 494), and (11) CTX-1 (KI 487). The experiment wasarranged in completely randomized design with ten replications.Parameters observed were trichome density, number of eggs and nymphson one cm2 of leaf and adult of B. tabaci on 3rd highest leaf of cottonplant. The result showed that trichome density was positively correlatedwith B. tabaci colonization (R=0,9701) in which higher trichome densityof cotton leaf has resulted in great colonization of B. tabaci. Bemisiatabaci colonisation was higher on CTX-1, CTX-8, Kanesia 8, and KK-3(150-250 individu/cm2 of leaf) due to dense trichome (150-300trichomes/cm2 leaf) as compared with other accessions, viz. TAMCOTSP 21, DP Acala 90, 619-998xLGS-10-77-3-1, Asembagus 5/A/1, Acala1517, A/35 Reba P 279, and Kanesia 1 which showed less density of leaftrichome (0-100 trichomes/cm2 of leaf) and B. tabaci colonization (< 100individu/cm2 of leaf).Key words : Cotton, Gossypium hirsutum, cotton accession, pest,Bemisia tabaci, trichome, colonization

Abstract

Biology of egg parasitoid ('Ooencyrtus malayensis Ferr.) ofpepper bug on alternate egg host (Nezara viridula L)Pepper bug (Dasynus piperis China) is an important pest of pepper. The pest widely spread in most pepper plantations of Indonesia. The level of the pest attack varied depended on crop cultivation treatment. Ooencyrtus malayensis is one of natural enemies which is able to control the population of pepper bug in plantation. The objective of this research was to study some aspects of the egg parasitoid biology by using eggs of Nezara viridula as the alternate host. This research was designed in a completely randomized block with four replicates. Dasynus piperis was collected from Bangka island and reared in Laboratory of the Research Institute for Spice and Medicinal Crops (RISMC ). Nezara viridula was fed with cowpea bean. This reascarch was conducted from July 1998 to February 1999. Experiment was divided into seven steps such as oviposition. pre adult period, production of parasitoid per host egg. egg preference, infestation period effect of cold storage (4°C) and parasitoid population. Research results showed that there were 85.5 parasitoid produced during its life time. Pre adult period lasted from 12 to 16 days, alternate host produced 3 parasitoids. The parasitoid pefeed the host of 0-2 days old. The eggs could be stored for 25 days in a efrigenerator (4°C). The longer the infestation and the larger number of parsitoid infested the larger numbers of parasitoid produced.

Abstract

Ideal land for growing rubber tree has increasingly limited. Hence farmers and companies were looking for alternative planting of rubber tree in non-conventional areas such as the land of tidal swamps. The study was conducted at Bangun Harjo Village, Air Sugihan Regency, Ogan Komering Ilir (OKI) District, South Sumatera Province, Indonesia from 2005 to 2014. The study was aimed to test the adaptability of six rubber clones in tidal swamps. The design used was a Randomized Block Design with rubber clones as treatment and three replications. Clones planted were IRR 39, IRR 118, IRR 220, PB 260, RRIC 100, dan BPM 24. In each treatment there were 40 rubber trees and 15 rubber trees as samples. The parameters observed were stem girth, bark thickness, and latex yield. The data were statistically analyzed using ANOVA, followed by Duncan Multiple Ranges Test (DMRT) at 5% levels. The results showed that rubber trees in tidal swamps would be able to mature tapping at the age of 60 month after planting (5 years) as long as using the recommended treatment. The growth of stems of each clone at the age of 12-60 month after planting in tidal land have different growth response. However, at the age of 60 BST the highest significant girth growth was IRR 39 (48.66 cm) while the lowest was the BPM 24 (44.17 cm) clone. The average yield per tree per taping (g/t/t) from 1st to 3rd years the highest was IRR 220 (26.23 g/t/t) and the lowest was IRR 39 (15.85 g/t/t). IRR 220 is adapted to tidal swamps.Keyword: Adaptability, rubber clones, tidal swamps, growth  AbstrakLahan yang ideal untuk pertumbuhan tanaman karet semakin terbatas sehingga banyak petani dan perusahaan mencari lahan alternatif untuk pengembangan karet di daerah non-konvensional seperti lahan pasang surut.

Abstract

Research on the effect of azadirachtin A isolated from neem tree (Azadirachla tndica A Juss) on msect Dolleschalia polibete. the most poten¬ tial insect destroying Graptophyllum pictum crop was caried out at the Entomological laboratory duing November 1997 to May 1998 The objective of the research was to evaluate the effect of azadirachtin A on some biological aspects of D. polibete. The formulation was obtained from FID Parry Ltd. (India), containing 1% azadirachtin A. The concentration recommended was 2-4 ml of formulation It of water or equal to 20-40 ppm of azadirachtin A The insects tested were obtained by reaing them in a screen house. Research was arranged in a completely randomized design, and randomized block design (for ovicidal). 6 treatments and 4-6 eplications. The treaments were concentrations of azadirachtin A (I) 80 ppm (2) 40 ppm (3) 20 ppm, (4) 10 ppm. (S) 5 ppm and (6) 0 ppm. Research consisted of three activities, i.e. effect of neem extract on (1) insect mortality and the survival rate. (2) as antifeedant, and (3) asovicidaon the insect. Results showed that azadirachtin A killed the insect slowly, it needed 3-10 days. Azadirachtin A acted as a growth inhibitor shown by the fact that at 5 and 10 ppm azadirachtin A, some pupae became malformed adults and other pupae died in a failed molt attempt Azadirachtin functioned as an antifeedant on some adult insects where the pupae were malformed and died on antifeedant and inhibit about 40% of feeding deference. Azadirachtin A also acted as an ovicidal inhibited about 50% egg-hatching.

Kadar kolesterol totaldiukur menggunakan metode CHOD-PAP, kadar kolesterol LDLmenggunakan metode PVS, kadar kolesterol HDL menggunakan metodeCHOD-PAP dan kadar triasil gliserol menggunakan metode GPO-PAP.Hasil penelitian menunjukkan bahwa konsumsi 0,945ml/hari VCO dan3,78ml/hari emulsi VCO selama 7 hari dapat menurunkan kadar kolesteroltotal, kadar kolesterol LDL, serta meningkatkan kadar kolesterol HDLdarah tikus Wistar secara signifikan (=0,05), sedangkan penurunan kadartriasilgliserol hanya ditunjukkan oleh konsumsi emulsi VCO (=0,05).Dengan demikian, emulsi VCO yang diperkaya dengan sari buah nenasberperan lebih baik dari VCO murni dalam menurunkan kolesterol padahewan uji tikus.Kata kunci: Virgin coconut oil (VCO), emulsi VCO, profil lemakABSTRACTEffect of Virgin Coconut Oil (VCO) Emulsion Diet onLipid Profile of White Rats (Rattus norvegicus)Virgin Coconut Oil (VCO) is a functional food product that ispopular in the society. VCO-emulsion is a VCO emulsified with pineapplejuice. This study was conducted to find out the effect of VCO-emulsiondiet on lipid profile of mouse (Rattus norvegicus) strain wistar which wasalready treated by inducting hyperlipidemia using lard (180g/100g) andyolk (4ml/days). This research was conducted from January to December2009 at the Laboratory of Coconut and Other Palm Trees ResearchInstitute (BALITKA), the Laboratory of FMIPA Sam Ratulangi UniversityManado, the Laboratory of Experiment Animal Research Unit GadjahMada University Yogyakarta, and the Laboratory of PAU IPB Bogor.Eighteen mice were randomly divided into 3 groups. Group I was thecontrol group treated with aquadest only, group II was treated with VCO-emulsion diet, and group III was treated with pure VCO diet. The contentof total cholesterol, HDL, LDL, and triacylglicerol were measured at theend of the treatment using enzymatic method. In this study, there weresome methods used for measurements: CHOD-PAP method for level oftotal cholesterol, PVS method for level of LDL cholesterol, CHOD-PAPmethod for level of HDL cholesterol, and GPO-PAP method for measuringlevel of triacylglicerol. The study results showed that diet of 0.945ml/daysof VCO and 3.78ml/days of VCO emulsion for 7 days significantlydecreased the level of total cholesterol and the level of LDL cholesterol,and increased the level of HDL cholesterol in the blood of Wistar mouse(α=0.05). Whereas it was shown that only by diet of VCO emulsion(α=0.05) decreased the level of triacylglicerol. Thus, VCO emulsionsignificantly lowered cholesterol in the experimental mouse better thanpure VCO diet only.Key words : Virgin coconut oil(VCO) , VCO emulsion, lipid profile

Abstract

ABSTRAKSanurus indecora merupakan salah satu hama utama yangmenyerang tanaman jambu mete di Propinsi Nusa Tenggara Barat. DiLombok Timur, hama ini diserang oleh cendawan Synnematium sp.Berdasarkan hal tersebut perlu penelitian untuk mengetahui apakahcendawan tersebut dapat digunakan untuk mengendalikan S. indecora.Penelitian yang bertujuan untuk mengetahui peranan Synnematium sp.dalam pengendalian S. indecora dilakukan di Desa Pohgading, KecamatanPringgabaya dan di Desa Wanasaba, Kecamatan Wanasaba, KabupatenLombok Timur dari bulan Juni sampai September 2004. Penelitian terdiriatas dua kegiatan yaitu di tingkat pot (bibit) dan lapang. Penelitian ditingkat pot terdiri atas tiga kegiatan yaitu aplikasi cendawan terhadap telur,nimfa, imago pada bibit jambu mete (10 telur/ serangga/ bibit). Rancanganyang digunakan ialah acak lengkap dengan empat perlakuan dan diulangenam kali. Pengamatan dilakukan terhadap jumlah telur atau seranggayang mati karena terserang Synnematium sp. mulai satu sampai tujuh harisetelah perlakuan. Penelitian lapang menggunakan rancangan acakkelompok yang disusun secara faktorial dengan dua macam faktor yaitupola tanam dan konsentrasi Synnematium sp. Parameter yang diamatiadalah populasi S. indecora, tingkat serangan, jumlah bunga hermaproditsebelum perlakuan dan jumlah buah yang berkembang. Hasil penelitianmenunjukkan bahwa cendawan Synnematium sp. yang diaplikasikan padanimfa S. indecora dan bibit menyebabkan kematian serangga tertinggimencapai 98,33%. Kematian serangga pada ketiga macam konsentrasiSynnematium sp. baik pada telur, nimfa dan imago tidak berbeda nyata.Dalam penelitian ini konsentrasi terkecil yaitu 20 g/l atau setara dengankonsentrasi spora 1,64 x 10 8  sudah efektif menyebabkan kematian S.indecora. Penurunan populasi S. indecora oleh Synnematium sp. efektifdengan konsentrasi 20 g/l sebesar 24,14% dibandingkan dengan kontrol.Tingkat serangan berkorelasi positif dengan populasi serangga.Kata kunci: Jambu mete, Anacardium occidentale L., hama, Sanurusindecora, pengendalian hayati, Synnematium sp. NusaTenggara BaratABSTRACTThe role of Synnematium sp. in controling Sanurusindecora JACOBI (Homoptera : Flatidae)Sanurus indecora is one of major pests attacking cashew plants inWest Nusa Tenggara Province. In East Lombok, this insect pest wasattacked by fungi of Synnematium sp. Based on that, the experiment wasconducted to find out whether the fungi could be used to control S.indecora or not. The objective of the experiment was to examine the roleof Synnematium sp. in the controlling S. indecora. It was carried out inPohgading, Pringgabaya and Wanasaba, District of East Lombok fromJune to September 2004. The experiment consisted of two activitiesnamely polybag stage and field activities. Polybag stage activitiesconsisted of three activities namely application of Synnematium sp. oneggs, nymphs, adults on seedling (10 eggs/insect/seedling). Theexperiment was arranged in a completely randomized design with fourtreatments and six replications. Observation was conducted on the numberof dead eggs, nymphs and adults attacked by Synnematium sp. from one toseven days after treatment. While field activities used a randomized blockdesign arranged in a factorial with two factors i. e. plant pattern andconcentration of Synnematium sp. Parameters observed were population ofS. indecora, the degree of attack, the number of hermaphrodite flowersbefore application and the number of developed fruits. Research resultsshowed that Synnematium sp. sprayed to nymphs of S. indecora andseedling caused the highest mortality of S. indecora that reached 98.33%.Mortality of S. indecora on the three concentrations either on eggs,nymphs and direct application to adults was not significantly different. Inthis experiment, the smallest concentration i.e. 20 g/l or equivalent withconcentration of spore 1.64 x 10 8  was effective to cause the death of S.indecora. The decrease of S. indecora population by Synnematium sp. waseffective with concentration of 20g/l as many as 24,14% compared withcontrol. The degree of attack was positively correlated with population ofS. indecora.Key words: Cashew, Anacardium occidentale L., pest , Sanurus indecora,biological control, Synnematium sp.
