Abstract

Various negative impacts of pesticides must be avoided by applying management principles that have as little negative impact on the environment as possible using an integrated pest management (IPM) approach. This study aimed to examine the diversity of arthropods and the feasibility of farming in IPM and conventional fields on soybeans. Arthropod sampling was carried out in September–December 2021 using a yellow pan trap, yellow sticky trap, and visual methods. The arthropod population found was analyzed using the T-test, and the level of arthropod diversity was calculated based on the diversity index (H'), species richness index (R), evenness index (E), and dominance index (C). The feasibility of farming on both fields was calculated using the R/C ratio and BEP prices. The results showed that the number of arthropods in IPM and conventional fields was significantly different. In both fields, the diversity index value was in the medium category, the species richness index value and the evenness index value were in the high category, and there was no dominance in both fields. Even though it belonged to the same category, the index value of arthropod diversity in the IPM field was higher than in the conventional field. In IPM and conventional fields, the R/C ratio values were 1.01 and 1.06, respectively, while the BEP value in IPM and conventional fields was IDR 10,601.44 and IDR 10,075.14.

Abstract

Rice, as a staple food, is widely produced across Indonesia. However, bacterial leaf blight (BLB) in rice is caused by Xanthomonas oryzae pv. oryzae (Xoo) has been reported to cause significant crop yield losses. The continuous use of chemical bactericides to control BLB is not environmentally sustainable. This study investigated the potential of the Binahong plant as a botanical pesticide to suppress the growth of Xoo bacteria. Binahong is readily available in Indonesia and can be propagated generatively and vegetatively. The research employed a Completely Randomized Design (CRD) experimental method to evaluate the effectiveness of Binahong leaf extract against Xoo pathogens in vitro at various concentrations (0.5%, 1%, 1.5%, 2%) alongside positive and negative controls. In-vivo observations were made on several parameters: seed germination percentage, disease incidence, incubation period, and plant length. Data analysis revealed that Binahong leaf extract inhibited the growth of Xoo bacterial colonies in vitro at all tested concentrations (0.5% to 2%). Furthermore, soaking rice seeds in Binahong leaf extract was effective in vivo at all concentrations, demonstrating significant differences compared to the negative control and no significant differences compared to the positive control.

Abstract

Leaf miners (Liriomyza sp.) are one of the pests affecting shallot plants. Attacks by Liriomyza sp. on shallot plants lead to tuber rot and leaves drying out, resembling burn damage. One control method is to utilize trap plants and refugia. Trap plants are specific species that attract pests, diverting them from the main crop. Refugia, on the other hand, are areas where pests can seek shelter, reducing their impact on the main crop. This study aimed to assess the impact of trap plants and refugia on the population and attacks of Liriomyza sp. in shallot crops. The research was conducted from June to September 2021 at the experimental field of the Faculty of Agriculture in Jatimulyo Village, Lowokwaru District, Malang City, East Java. Observation parameters included the population of Liriomyza sp., damage intensity, population of natural enemies, plant height, and number of leaves. The results indicated that different types of trap plants significantly influenced the population of Liriomyza sp. and damage intensity compared to the control treatment. However, different trap plant types did not significantly affect the population of natural enemies. The natural enemies identified included Vespidae, Coenosia sp., and Opius sp. Additionally, various trap plant types did not significantly impact plant height and the number of leaves.

Abstract

Complex rice systems are a type of farming system that provides shelter for various insects, thereby reducing pests and plant diseases while enhancing farmer's economies. Plants and other components integrated with rice enhance beetle diversity and abundance in complex rice systems. This study aimed to determine the diversity and abundance of beetles in a complex rice system and the factors that can influence them. The study was conducted on a complex rice system farm in Sukorejo Village, Gondanglegi District, Malang Regency. Observations were made five, seven, and nine weeks after planting the rice. Beetles were sampled using pitfall traps and farmcop traps. The results showed differences in the diversity and abundance of beetles between farms with monoculture systems and those with complex rice systems. However, plant age, temperature, and humidity did not correlate with beetle diversity and abundance. This research concludes that complex rice systems are better than monoculture systems.

Abstract

Soil is a habitat for many types of microbes that have a role in maintaining soil nutrition, and most of them grow around plant roots. Factors that are quite influential in the growth process are the hormone auxin, which has a role in stem bending and stimulates differentiation. This study aimed to obtain a genus of IAA hormone-producing rhizosphere fungi (Indole-3-Acetic Acid) and determine the effect of environmentally friendly and conventional land cultivation on the diversity of IAA hormone-producing fungi at Agrotechnopark UB Cangar Garden. Fungi isolates were cultured on Potato Dextrose Agar (PDA) and Potato Dextrose Broth (PDB) media enriched with tryptophan as a precursor to form IAA. IAA measurements were carried out qualitatively by adding the Salkowski reagent and quantitatively by measuring the absorbance. As many as 10 rhizosphere fungal isolates were obtained from environmentally friendly land and 8 fungal isolates from conventional land, which produced IAA hormones. The fungal genera obtained included Acremonium, Aspergillus, Colletotrichum, Fusarium, Penicillium, and Trichoderma. Environmentally friendly cabbage fields (average: 283.8 ppm) showed higher yields than conventional fields (average: 140.9 ppm) in producing IAA hormones. There was a correlation between soil pH and organic matter on fungal diversity, with a correlation value of 0.878. The diversity index value of rhizosphere fungi was 1.359; the evenness index was 0.845, and the dominance index was 0.302 on environmentally friendly land. The diversity index value of rhizosphere fungi was 1.213; the evenness index was 0.875, and the dominance index was 0.344 on conventional land.
