Abstract

Rice (Oryza sativa L.) is one of the main food crops for most Indonesians. Integrated agriculture or mixed agriculture is a concept of agriculture that supports sustainable agriculture by involving crops and animals in the same land to reduce external inputs, due to mutual support between one component and another. This research was conducted with the aim to see the effect of duck rice cropping patterns in reducing pest and weed populations in rice plants (Oryza sativa L.). The research was conducted on farmers' land in Keramat Gajah Village, Galang District, Deli Serdang Regency, North Sumatra Province. An experimental approach was used in the investigation, including treatments both with and without ducks. Ducks were introduced to the paddy field when the plants were 21 days old until the plants were 55 days old. The number of ducks used was 10 ducks per rante (400 m2). The data obtained were tested using paired t-test analysis. The outcomes demonstrated that, whereas the treatment using ducks did not significantly alter the population of gold snails, it did considerably alter the populations of earthworms (10 and 12 WATP) and weeds (8 and 10 WATP). Keywords: ducks, earthworms, gold snails, paddy, weeds

Abstract

Banyak penelitian telah dilakukan untuk mendeteksi jamur entomopatogen di dalam tanah menggunakan metode qPCR. Namun, beberapa penelitian menunjukkan bahwa metode qPCR belum mampu mendeteksi jamur di sampel tanah yang disebabkan oleh sedikitnya kemelimpahan jamur pada sampel tanah yang diuji. Untuk mengatasi masalah tersebut, pada penelitian ini dilakukan penambahan massa jamur target di dalam tanah pada tingkat tertentu melalui metode semi-kultur dengan tujuan untuk meningkatkan sensitivitas qPCR. Pertama, dipilih media selektif yang cocok untuk kultur keempat target jamur entomopatogen (Cordyceps militaris, Beauveria bassiana, Isaria fumosorosea, dan Metarhizium anisopliae). Kedua, dengan menggunakan media yang dikembangkan, hubungan antara unit pembentuk koloni (CFU) dan DNA tanah standar ditentukan. Ketiga, qPCR dilakukan terhadap ekstrak DNA yang diperoleh dari koloni jamur tiap level. Hasil menunjukkan bahwa media kultur tipe 3b menjadi media selektif yang terbaik untuk kultur jamur. Namun, hubungan linier dengan korelasi kuat antara suspensi jamur dengan nilai Ct belum dapat diperoleh sehingga metodologi semi-kultur tidak berhasil meningkatkan sensitivitas deteksi jamur entomopatogen dari sampel tanah menggunakan metode qPCR. Modifikasi ekstraksi DNA untuk meningkatkan kepadatan DNA dalam ekstrak perlu dilakukan untuk keberhasilan deteksi jamur entomopatogen.

Abstract

Waste-related environmental pollution can affect health and needs to be addressed seriously.   These days, the majority of organic waste is turned into eco-enzymes and fertilizer.   In addition, insects can be used as bioconversion agents to control organic waste in homes.   The Black Soldier Fly, or BSF fly, is the insect.   The ladies of the Aisyiyah Branch in Medan Denai, North Sumatra Province, are the partners of the Muhammadiyah Development Partnership Program (PKPM) in this project.  By using maggots as a bioconversion agent and teaching Aisyiyah mothers about the use of maggots as fish and poultry feed, the program aims to turn household trash into a product of economic value, which should raise household income.  The technique employed in this activity began with socialization followed by maggot cultivation training for mothers. Direct interviews were conducted as a way to evaluate activities for Aisyiyah mothers. The results achieved were an increase in knowledge about maggots by around 75% and 25% of Aisyiyah mothers understood maggot cultivation.

Abstract

The coconut rhinoceros beetle Oryctes rhinoceros is one of the key pests in oil palm plantations. Controls carried out by farmers always use insecticides, which can adversely affect the agroecosystem. Community Service Activities carried out to introduce and provide understanding to partner farmers about alternative controls that are more environmentally friendly by utilizing the natural enemies of predator ants Myopopone castanea. The method used in this service is the extension method. The result is that farmers understand that the ants they usually find in their oil palm plantations are friends for oil palm farmers, so their existence must be maintained so that they can benefit the farmers and the oil palm plantation environment.

Abstract

Plant pathogens such as Colletotrichum, Pestalotiopsis, and Phytophthora are major causal agents of significant yield losses in tropical horticultural crops. Among various biological control agents, Trichoderma species have been widely studied due to their antagonistic capabilities, rapid colonization, and ability to produce hydrolytic enzymes. Dual-culture and split-plate assays are commonly used to evaluate direct inhibition mechanisms and inhibition mediated by volatile compounds. This study aimed to evaluate the antagonistic potential of Trichoderma reesei against three tropical pathogens using both assay methods. The antagonistic potential of Trichoderma reesei against three major tropical plant pathogens—Colletotrichum gloeosporioides, Pestalotiopsis microspora, and Phytophthora palmivora—was assessed using dual-culture and split-plate techniques. In the dual-culture assay, T. reesei showed varying levels of inhibition across the tested pathogens. The highest mean inhibition was observed against P. microspora (89.37 ± 1.48%), followed by C. gloeosporioides (87.22 ± 2.01%), and the lowest against P. palmivora (84.37 ± 1.35%). Statistical analysis (GLM, F = 9.38; p = 0.0063) revealed significant differences among pathogens, with Tukey's test indicating that inhibition against Pestalotiopsis was significantly greater than against Phytophthora palmivora. The results indicate that Trichoderma reesei exhibits more effective antagonistic activity against Pestalotiopsis than against Phytophthora palmivora. This suggests that the inhibitory mechanisms of T. reesei are more specific and potent against certain pathogens, particularly necrotrophic fungi such as Pestalotiopsis. This specificity enhances its value as a biological control agent by demonstrating selectivity toward target pathogens. Another advantage of T. reesei is its ability to produce hydrolytic enzymes, such as chitinase and glucanase, that degrade the cell walls of pathogens. This enzymatic activity strengthens the effectiveness of biological inhibition without causing negative environmental impacts. Therefore, T. reesei has strong potential as an environmentally friendly alternative to synthetic chemical fungicides. Users are encouraged to integrate T. reesei with Integrated Pest Management (IPM) practices. Combining it with proper cultivation techniques—such as field sanitation, crop rotation, and the use of resistant varieties—will enhance overall disease control effectiveness. Additionally, environmental factors such as humidity, temperature, and soil pH should be considered, as they influence the activity of T. reesei. Optimizing these conditions will improve colonization and antagonistic activity of this microorganism in the field.
