Abstract

The Correlation Test and Path Analysis of Antrachnose Disease Resistance of Pepaya ABSTRACT. The aims of this research were to estimate the correlation coefficient among agronomic traits on antrachnose disease resistance of papaya and evaluate the direct and indirect effects of those traits on antrachnose disease resistance of papaya. The result showed that fruit length, flesh thickness, percent symptoms had positive correlation to severity disease and dry of fruit ripe, percent TSS, flesh fimness had negative correlation to severity disease. Path analysis applied an agronomic and resistance character on antachnose disease resiistance indicated that antrachnose disease resistance was directly affected by percent symptom. The largest compound path coefficient of agronomic traits on antrachnose disease resistance that percent TSS and flesh thickness via percent symptom.

Abstract

Exploration and Characterization of Mango Variety Resist of Cork bore in Nanggroe Aceh DarussalamABSTRACT. The basic knowledge about mango resistance of trunk bore in the field and laboratory is early step to make mango resistance breeding. The result of research could be positive correlation between resistance character and commercial character. The research consisted two parts, survey of varieties of mango on field and the resistance test of trunk borer of mango on laboratory. The survey was done by characterization of mango varieties on Aceh Besar and Banda Aceh. The laboratory research was held by varieties of mango (Arumanis, Gadung, Golek, Cengkeh, Apel and Local) the test of resistance of trunk borer of mango. All treatment was assigned in Completely Randomized Design with 3 replications. The observation was done on characterization of mango varieties, percent of damage, damage index, insect identification and soluble solids contents. This result showed that there are six varieties of mango (Arumanis, Cengkeh, Gadung, Apel, Golek and Local (cengkir) has be found on Banda Aceh and Aceh Besar. Percent damage of trunk borer of mango on Aceh Besar (50-100%) and intensity of damage (10-60%). Percent damage (0-100%) and intensity of damage (0-30%) on Banda Aceh is Lower than Aceh Besar. The soluble solid contents of mature fruit of Golek, Gadung, Cengkeh and Arumanis 13.90-15.68 0brix) higher than Apel and Local (11.54 and 12.72 0brix). Result of identification of insect that trunk borer og mangoes on Banda Aceh and Aceh Besar is Rhytidodera simulans Wh.

Abstract

ABSTRAK. Eksplorasi dan Penapisan Genotipe Kakao Plasma Nutfah Aceh untuk Memperoleh Genotipe Kakao Tahan Penyakit Busuk Buah,  merupakan penelitian dasar untuk mendapatkan informasi metode yang efektif dalam melakukan seleksi untuk memperoleh tanaman kakao tahan terhadap penyakit busuk buah. Tujuan penelitian pada tahun pertama ini adalah diperoleh sumber inokulum yang memiliki tingkat patogenisitas yang tinggi, diperoleh metode inokulasi yang efektif, adanya korelasi positif antara tingkat ketahanan di lapangan dan di laboratorium. Hasil penelitian menunjukkan bahwa dari hasil uji patogenisitas asal inokulum yang diperoleh dari buah yang bergejala dilapangan, hamper seluruhnya menunjukkan tingkat patogenesitas yang tinggi.  Metode inokulasi buatan yang efektif adalah dengan cara melukai dan menempel baik di daun maupun dibuah. Namun metode inokulasi untuk memperoleh genotype yang tahan pada buah adalah dengan menempelkan potongan inokulum tanpa dilukai. Pathogenicity Test  Isolate Some Black Pod Diseases of Cocoa Aceh and Evaluation of the Effectiveness of Inoculation MethodsABSTRACT. Exploration and Screening Genotypes Aceh Cocoa Germplasm Resistant to Acquire Genotype Cocoa Black Pod Disease, is a basic research to obtain information effective method of selecting to obtain cocoa plants resistant to fruit rot disease. The purpose of this study is the first year that has acquired a source of inoculum levels are high pathogenicity, obtained an effective inoculation method, a positive correlation between the level of resistance in the field and laboratory. The results showed that the origin of the inoculum pathogenicity test results obtained from symptomatic fruit in the field, almost entirely showed a high degree of pathogenicity. Effective method of artificial inoculation is to hurt and stuck both in leaf and pod. However, inoculation method for obtaining genotypes  resistant to the fruit is by gluing pieces of inoculum unharmed.

Abstract

Telah dilakukan evaluasi mutan-mutan kedelai Kipas Putih generasi ke 2 (M2) terpilih untuk mendapatkan galur berpotensi produksi dan kadar protein tinggi. Iradiasi sinar gamma dilakukan di Puslitbang Teknologi Isotop dan Radiasi BATAN,  Pasar Jumat Jakarta. Sebagai kontrol digunakan varietas Kipas Putih yang belum diradiasi. Penelitian dilakukan di Kebun Percoban Fakultas Pertanian Universitas Syiah Kuala, Darussalam - Banda Aceh yang berlangsung dari bulan Januari 2015 sampai bulan Mei 2015. Penelitian ini menggunakan rancangan acak kelompok (RAK) pola non faktorial. Penelitian ini  menggunakan 14 genotipe dan 1 genotipe kontrol varietas Kipas Putih tanpa radiasi, terdiri dari 2 ulangan sehingga terdapat 30 unit satuan percobaan. Parameter yang diamati adalah tinggi tanaman, jumlah cabang, jumlah polong, jumlah polong bernas, berat 100 butir biji, jumlah biji per tanaman, dan berat biji per bedeng, untuk kualitas biji dilakukan analisis kadar protein, lemak, serat dan abu. Hasil penelitian menunjukkan bahwa genotipe berpengaruh sangat nyata terhadap berat 100 biji tanaman, namun tidak berpengaruh terhadap tinggi tanaman, jumlah cabang, jumlah polong, jumlah polong bernas, dan jumlah biji sedangkan kadar protein tertinggi pada genotipe KP200-51 (G9) (39.01%), lemak KP200-52 (G10) (15,16%), serat KP200-10 (G5) (12,54%) dan abu KP200-28 (G6) (6,83%).

Abstract

Inhibited of Growth of Volvoriella volvaceae by Rhizopus sp some of cultivated mediaABSTRACT. The study was conducted in Dhampulo and Plant Protection Laboratory Agriculture Faculty of Syiah Kuala University during July to September 2011. The objective of the study were to know inhibited of growth of Volvoriella volvaceae by Rhizopus so all of cultivated media. The study was arranged in non factorial Randomized Completely Block design with six treatment and three replication. The treatments were straw media; cardboard box media; cane pulp media; sawdust media; water hyacinth media and fibrous shell. The result showed that Volvoriella volvaceae growth better on strow media than other media.
