Abstract

Dieback disease caused by Lasiodiplodia theobromae is an important disease on the nutmeg tree in Aceh Selatan. The disease has been widespread in the district. One alternative to control the disease is the use of antagonistic fungi from the nutmeg tree to inhibit the development of the cause of the disease. In vitro experiments were carried out by evaluating 4 types of antagonistic fungi from the nutmeg tree to L. theobromae. The aim of the study was to determine the potential of in situ soil fungus as an antagonistic agents against L. theobromae, the cause of dieback disease on the nutmeg tree in Aceh Selatan. Microbial isolation using serial dilution method. The fungus test which was successfully isolated as an antagonist candidate was carried out through the dual culture method. The results showed that four fungi namely; Trichoderma harzianum, T. virens, T. asperellum, and Talaromyces pinophilus have the potential as antagonistic agents against pathogens cause dieback disease on the nutmeg tree in Aceh Selatan, with inhibitory power ranging from 66-100% in vitro.

Abstract

Dieback disease caused by L. theobromae has destroyed nutmeg plantations in Aceh Selatan. Until now, effective control has not been found, while farmer continue to use pesticides that have a negative impact on the environment. Therefore, biological control is an alternative to environmentally friendly control that is being promoted. The purpose of this researth was to control dieback by inducing resistance using three spesies of Trichoderma (local isolates) from the Nutmeg. The three isolates were isolates of plant origin and the nutmeg seeds used are one year old. This researth used a randomized blok design with three species of Trichoderma (T. virens, T. asperellum, and T. harzianum), three doses (5, 10, 15 g), and three replicates.The variables observed were the incubation period, disease incidence, length of stem discoloration, height of the plant, and plant wet weight. Thr result showed that all species of Trichoderma tested were able to induce systemic resistance and promoted plant growth, by inhibiting the incubation period, disease incidence, length of discoloration, increasing height and weight of plant. The treatment of T. virens 10 g was the best treatment result compared to the others.

Abstract

This study aimed to identify the honesty level of students in online exams assisted by supervisory robots on the autoproctor application as an effort to improve the quality of online learning. The sample of this study were 34 students majoring in Physics Education FKIP USK who were selected randomly. Data were collected from test results using a google form embedded the autoproctor to detect student honesty during online exams and student response results from an honesty questionnaire based on four indicators developed by Ashton, M. C, et.al namely: sincerity, fairness, greed avoidance, and modesty. The data were analyzed using quantitative descriptive analysis. This study shows the honesty level of students recorded by the application is medium level and is supported by the results of honesty questionnaire responses. The response results show the level of honesty is in the very high to the medium range, while the test results using the autoproctor are in the very high to the very low range. There were some students who detected high honesty levels based on the results of the questionnaire responses but were detected very low on the autoproctor application. In applications, it was found evidence of fraud by students but they were not true after further observation, so it was necessary to inform the rules that must be obeyed using this application before the test. The findings of this study could be the basis for sustainable professional development using the autoproctor application in detecting student honesty in online exams

Komparasi Keanekaragaman Serangga pada Tanaman Cabai Merah, Cabai Rawit dan TomatAbstrak. Pola penanaman monokultur merupakan penanaman satu jenis tanaman pada satu satuan luas lahan tertentu. Menurunnya produktivitas dari ketiga komoditi tersebut di Provinsi Aceh disebabkan oleh pengelolaan agroekosistem yang tidak berimbang antara faktor abiotik dan biotik. Salah satu penyebab ketidakseimbangan agroekosistem tersebut akibat penggunaan pestisida yang tidak sesuai dengan prinsip PHT (Pengelolahan Hama Terpadu). Perangkap yang digunakan dalam penelitian ini adalah yellow sticky trap. Peubah yang diamati meliputi populasi serangga, indeks keanekaragaman, indeks kelimpahan. Pada pertanaman cabai merah terdapat 7 ordo serangga dengan total serangga 752 individu. Pada cabai rawit terdapat 6 ordo dengan total serangga 824 individu, sedangkan pada tanaman tomat terdapat 7 ordo serangga dengan total serangga 855 individu. Ordo diptera yang paling dominan yaitu 12 famili, sedangkan ordo yang paling sedikit ditemukan pada ordo lepidoptera 1 famili. Nilai indeks keanekaragaman antar ketiga tanaman berkisaran (2,80-2,93), indeks kelimpahan antar ketiga tanaman berkisaran (00,7-00,9). Comparative Diversity Of Insects On Red Chillies, Chillies And Tomatoes Abstract. The monoculture planting pattern is the planting of one type of plant on a certain unit of land area. The decline in productivity of these three commodities in Aceh Province was caused by the unbalanced management of the agroecosystem between abiotic and biotic factors. One of the causes of the imbalance in the agroecosystem is the use of pesticides that are not in accordance with the principles of IPM (Integrated Pest Management). The trap used in this research is yellow sticky trap. The variables observed included insect population, diversity index, abundance index. In the red chili crop there are 7 insect orders with a total of 752 insects. In cayenne pepper there are 6 orders with a total of 824 insects, while in tomato plants there are 7 insect orders with a total of 855 insects. The most dominant order of Diptera was 12 families, while the least order was found in the order of lepidoptera 1 family. The diversity index value between the three plants ranged (2.80-2.93), the abundance index between the three plants ranged (00.7-00.9).
