The purpose of this study was to determine whether P60 could induce resistance in local Aceh chili varieties to begomovirus and compared with national varieties. This research was conducted at the Experimental Farm, Genetics and Plant Breeding Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh, from March to July 2021. This study used a factorial randomized block design. The tested factors consisted of two factors. The first factor is bio priming. The second factor consists of four local Aceh chili varieties, namely: V1 = Odeng, V2 = Lanyoe, V3 = Super Lamando and V4 = LamandoLapaben and one national variety, namely V5 = Baja F1 as a comparison variety. The results showed that the best local Aceh variety was LamandoLapaben for the variables of resistance response, incubation period, disease intensity, disease incidence, stem diameter, and crown width. The best local variety Aceh Lanyoe on plant height and dichotomous height parameters. Giving P60 can reduce the percentage of disease incidence by 52.00% and slow down the process of emergence of disease symptoms (incubation period) 27.11 DAP. The best combination treatment was the LamandoLapaben variety, which was 1.41 milligram Units-1 (Umg)-1.
Abstrak. Penelitian ini bertujuan untuk menguji aktivitas ekstrak etil asetat babadotan dari berbagai ketinggian tempat dan konsentrasi terhadap pertumbuhan gulma bayam duri. Penelitian ini dilaksanakan di Laboratorium Ilmu Gulma Program Studi Agroteknologi dan Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Banda Aceh, serta Laboratorium Analisis Kimia Fakultas Matematika dan Ilmu Pengetahuan Alam (FMIPA), sejak September 2017– Januari 2018. Bahan yang digunakan adalah benih bayam duri, yang diperoleh dari Kecamatan Delima Kabupaten Pidie dan daun babadotan yang diperoleh dari 3 daerah dengan ketinggian yang berbeda yaitu Kecamatan Indrapuri Kabupaten Aceh Besar (19 mdpl), Kecamatan Lembah Seulawah Saree Kabupaten Aceh Besar (261 mdpl) dan Kecamatan Takengon Kabupaten Aceh Tengah (1259 mdpl) dengan konsentrasi 5, 10 dan 15% sebagai bioherbisida. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) pola faktorial 3 3 dengan 3 kali ulangan. Faktor pertama yaitu ketinggian tempat dengan 3 taraf dan faktor kedua konsentrasi dengan 3 taraf. Ekstrak yang dihasilkan pada ketinggian tempat yang berbeda dan konsentrasi ekstrak etil asetat berpengaruh nyata terhadap laju tinggi, jumlah daun, diameter batang, persentase pengendalian dan panjang akar. Terdapat interaksi antara ketinggian tempat dan konsentrasi terhadap persentase pengendalian pada 7 dan 14 HSA. Ekstrak yang dihasilkan pada ketinggian 9 mdpl dengan konsentrasi 10% dapat mengendalikan gulma bayam duri hingga 100% pada 7 HSA.The Test of Effectiveness Whiteweed Ethyl Acetate Extract (Ageratum conyzoides L.) from Various Altitudes And Concentration Against the Growth of Spiny Amaranth Weed (Amaranthus spinosus L.)Abstract. This study aims to examine the activity of ethyl acetate fraction of whiteweed extract from various altitudes and concentration againts the growth of spiny amaranth. This research was conducted at Laboratory of Weed Science, Agrotechnology Department, and Experimental Garden, Agriculture Faculty, Syiah Kuala University Banda Aceh, and Laboratory of Chemical Analysis Mathematics Faculty and Natural Science, from September 2017 to January 2018. The materials used is spiny amaranth seed that obtained from Subdistrict of Delima, District of Pidie and babadotan leaves obtained from three regions with different altitude that is Subdistrict of Indrapuri, District of Aceh Besar (19 masl), Subdistrict of Subdistrict of, District of Aceh Besar (261 masl) and Subdistrict of Takengon District of Aceh Tengah (1259 masl) with each concentration 5, 10 and 15% as bioherbicide. This research using Randomized Completely Design with Factorial pattern which has 3 × 3 treatments and 3 replication. The first faktor is altitude and second is concentration of ethyl acetate extract. Ethyl acetate extracts that produced in different altitudes and concentrations were significantly influence the high rate of spiny amaranth, number of leaves, stem diameter, control percentage and root length. There is an interaction between altitude and concentration on the percentage of control at 7 and 14 HSA. Extracts produced at an altitude of 9 masl with a concentration of 10% can control spinach weeds up to 100% at 7 HSA.
The productivity of pepper plants is strongly influenced by climatic and weather conditions as well as pests and diseases. One of the major losses in chili farming is the pest attack, such as whiteflies (Bemisia tabaci Genn.), a virus vector. Evaluation of the resistance of pepper plant germplasm against Begomovirus infection needs to be carried out, evaluate genetic diversity, estimate heritability values, and obtain a selection character for the resistance of chili plants Begomovirus. This research was conducted at Experimental Garden, Faculty of Agriculture, Universitas Syiah Kuala, and the Laboratory of Genetics and Plant Breeding, Faculty of Agriculture, Universitas Syiah Kuala from January to May 2020. Three varieties Gada, Anies and Selekta with seven test genotypes i.e F6 Gada, Seloka 4-10-2-2, F5136074-1-4-3, F5074136-2-3-2, F5074035-2-1-2, F5074035-2-4-2, F5074077-1-1-3 were screened for their resistance against Begomovirus. This study was designed using a non-factorial Randomized Block Design (RBD) and scoring parameter Begomovirus symptom. Tukey’s HSD, the standard deviation of genetic variance, heritability, and correlation were performed to analyze the data. The lowest disease intensity occurred in genotype F6 Gada with a percentage of 12.08% disease intensity (slightly resistant), and the highest level of disease intensity occurred in F5074035-2-4-2 with a percentage of 30.94% (susceptible). Variables symptom scoring, disease intensity, and incubation period were the most effective variables for selecting pepper resistance against Begomovirus infection based on broad-sense heritability values.
The purpose of this study was to determine the type of rhizobacteria isolates indigenous that have the potential as biocontrol agents on the pathogen Synchytrium pogostemonis that causes budok disease on patchouli. The research was carried out at the Seed Science and Technology Laboratory of the Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University and the Experimental Garden of the Sektor Timur, Faculty of Agriculture, Darussalam Banda Aceh. The time of the study began from January to May 2021. This experiment was arranged based on a completely randomized design with a non-factorial pattern with 15 treatments consisting of 14 rhizobacterial isolate treatments and a control treatment (without rhizobacteria). Each treatment was repeated 3 times. The results showed that isolates of rhizobacteria PS 4/5 and PS 5/6PK were the best treatment as biocontrol agents against the pathogen S. pogostemonis that causes budok disease in patchouli based on disease incubation period, intensity of disease attack, weight of wet stover, and weight of dry stover. The results of the peroxidase enzyme activity test showed the highest activity in patchouli treated with PS 6/3A rhizobacteria isolates with an absorbance value of 1.66 U ml-1.Keywords: Patchouli (1), Plant (2), Rhizobacteria (3), Indigenous (4).

Deconstruction in short story "I Want My Son to Become a Murderer" shows a binary opposition which leads into an understanding that there is no hierarchy opposition. Derrida deconstruction in literary work aims to show logical and rhetorical non-equivalence between what explicitly written and what is implicitly hidden in the text. The deconstruction study shows how the contradictions should be uncovered from the text which called dissemination. The result of the analysis shows the opposition found are: (1) opposition between title and story; (2) opposition between the story and the footnote; (3) opposition between intuitive comprehension and logical reasoning; (4) opposition between fact and fiction; (5) opposition between “I lyric” and many people; and (6) opposition between the writer and the reader.
