Abstract

The improper use of pesticides can lead to significant negative impacts on both the environment and human health. This study evaluates horticultural farmers' compliance with recommended pesticide practices in Ogan Ilir Regency, South Sumatra, and examines the effects on pests, diseases, natural enemies, and pesticide residues in their products. This research used a direct survey method on horticultural crop cultivation land in Ogan Ilir Regency, South Sumatra, and sent plant samples to be tested for pesticide residue levels. The results showed that low-compliance farmers had high pest populations, high disease incidence, and fewer natural enemies, while high-compliance farmers had low pest populations, low disease incidence, and more natural enemies. Pesticide residue tests indicated that products from low-compliance farmers contained Amitraz residues of 0.02 mg/kg and Chlorantraniliprole residues of 0.14 mg/kg, while medium-compliance farmers had Amitraz residues of 0.02 mg/kg and Chlorantraniliprole residues of 0.18 mg/kg. No pesticide residues were detected in products from high-compliance farmers. The study concludes that adherence to recommended pesticide use significantly influences the balance of agricultural ecosystems and the safety of agricultural products.

(pp. 731–742).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).There are many factors that prevent Indonesia from exporting mustard fruits to other countries, one of which is that mustard fruits spoil quickly. Mustard fruit is an agricultural product that cannot be stored for a long time, so it is at high risk in marketing. This field practice aimed to identify insect species found on mustard fruit in the ATC (Agriculture Training Center) field and in places overgrown with mustard fruit inside the Sriwijaya University Indralaya campus. This field practice uses direct survey methods and insect identification using the Google Picture Insect application. The results showed that 4 different orders and 7 different families were found. The insect orders are Diptera, Hemiptera, Hymenoptera, and Lepidoptera. For the Diptera order, 2 families were found, namely D. melanogaster from the Drosophilidae family and B. dorsalis from the Tephritidae family. The Lepidoptera order also found 2 families, namely O. subnotata from the Erebidae family and L. omnivora from the Psychidae family. As for the other 3 orders, each insect order only found one family. Of all the insects identified, C. pennsylvanicus and P. manihot were the two most common insect species found on the three observed sawo plants. The number of fruit flies found on sawo plants was 83, the intensity of attack on sawo fruits was up to 29.61%. Based on the results found there are 7 species of insects and 1 species of spiders that are found to live in mustard plants. The 7 insect species are Drosophila melanogaster, Bactrocera dorsalis, Phenacoccus manihot, Tartessus ferrugineus, Camponotus pennsylvanicus, Orvasca subnotata, Liothula Omnivora, and the spider species found is Telemonia dimidiate. The ant species Camponotus pennsylvanicus can be found in all parts of the sawo plant. Insect species in the ATC field included B. dorsalis, P. manihot, C. pennsylvanicus, and O. subnotata. And one spider species found in the ATC field is the spider species T. dimidiata. Meanwhile, at least 3 insect species were found in fisip fruit plantations. Insect species found in fisip fruit plantations are D. melanogster, T. ferrugineus, and L. omnivora.

Sugiarto, M.H., Irsan, C., Warman, A., Laila, M.R., Nuraini, F., Putri, O.A. (2024).Phytophagous and Entomophagous insects on bitter gourd (Momordica charantia L) plants in North Indralaya District, Ogan Ilir Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 843–853). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Phytophagous insects are plant-eating insects or what are usually called herbivores. These phytophagous insects are referred to as pests if their eating behavior on plants causes economic losses. Meanwhile, predatory insects or entomophages are a group of natural enemies that are very important in helping reduce pest populations. This research aims to identify and determine insect species that live on plants or around plants and their role on plants and other insect species. Research was conducted on 2 vegetative and generative bitter melon fields among farmers in North Indralaya District, Ogan Ilir Regency, South Sumatra Province in September 2021. The observation method was carried out using 2 traps, namely the pan trap and the pitfall trap. This observation was carried out every morning at a distance of 12 hours for pan traps and 24 hours for pitfall traps within 1 week. Observations on bitter melon plants show that arthropod species use pan traps. The results obtained were 7 orders, 16 families and 17 species of arthropods on bitter melon plants which were successfully identified using pan traps and 6 orders and 9 families and 8 species of arthropods which were successfully identified using pitfall traps.

Umayya, L.N., Irsan, C., Mulawarman, M., Shobiha, S.N., Fani, G., Apriyani, M., Aulia, H., Mirsya, S.A. (2024). Insects found on duku plants (Lansium domesticum Corr) in Muara Enim Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 212–220). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cultivation of duku plants has obstacles such as applying of low cultivation technology and interference from Plant Disease Organisms (OPT). Therefore, we need to know the identification of pests that attack duku plants in the area to determine what pest species are causing damage to duku plants. The method used is direct observation and interviews. The results of observations carried out in farmers' duku gardens in Kepur Village, Muara Enim Regency show that insects that have the potential to become pests consist of 6 species, such as red caterpillars, fruit flies, ladybugs, tree termites, plutellidae larvae, and dompolan lice, in contrast other pests attack duku plants are bats and ants. Red caterpillars attack the skin on duku stems, termites attack the lower stems, dompolan lice attack the fluid on the leaves, ladybugs attack young fruit and fruit flies attack the inside of the fruit. Production can be reduced by up to 50-100 kg/stem due to pest attacks on duku plants. Dompolan lice attack duku plants which have a symbiotic relationship with ants. From this description, it was found that tree termite pests are the pests with the highest population and most insects attack the stems of plants. To develop duku production, further research is needed to control pests on duku plants.

(pp. 127–134).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Grasshoppers are animals that belong to the insect class. The diversity of grasshoppers can influence the diversity of parasitoids and predators in an ecosystem. Environmental factors are factors that influence the presence of grasshoppers in a habitat. The aimed of  this research was to the morphology of stick grasshoppers (Eurycnema goliath) kept on Red Shoot Plants (Myrtaceae) is to observe and describe the morphology of grasshoppers, including body structure, color and size related to their adaptations. This research also aims to assess the interaction of grasshoppers with red shoot plants, such as food preferences and their impact on plant growth. The method used in this research is a survey method by observing and directly measuring the length of the stick grasshopper (E. goliath). The data obtained from these observations are presented in the form of tables and pictures and the results of the observations obtained are described. The results obtained from this research are to understand the life cycle of stick grasshoppers starting from eggs, nymphs, and then imago. The stick mantis eggs are dropped to the ground by the female imago to hatch among the leaves. When entering the nymph phase, the stick grasshopper begins to climb up the stem of the plant that is its habitat. In the first instar nymph phase, the stick grasshopper is whitish brown, then in the second instar the color changes to light brown. The third and fourth instar nymph phases show a change in color to brown, while in the fifth instar, the stick grasshopper is greenish brown. The imago phase is marked by a color change to green. This research shows that keeping stick grasshoppers on plants of the Myrtaceae family helps understand their morphology and type of reproduction. This animal is included in the group that undergoes incomplete metamorphosis.

Abstract

Vector-borne disease such as Dengue Hemorrghagic (DHF), transmitted by Aedes aegypti and Aedes albopictus, remain a significant public health concern in Indonesia. Controlling these disease often involves insectides; however, the negative impact of chemical insecticides have prompted interest in organic alternatives derived from plants. Certain weeds, including cogon grass (Imperata cylindrica), wild sugarcane (Saccharum spontaneoum), and needle grass (Andropogon aciculatus), have shown potential as botanical insecticides. Research findings showed that weed root extracts significantly affect larval mortality rate of Ae. Aegypti. At 1000 ppm, larval mortality was significantly higher compared to 100 ppm and the control, while treatments of 1 ppm and 10 ppm showed similar results to the control. Probit analysis revealed that I. cylindrica root extract achieved an LC50 of 974.99 ppm within 24 hours, indicating it could kill 50% of Ae. Aegypti larvae. Within 48 hours, the LC50 dropped to 889.20 ppm. Toxicity tests further revealed significant differences in Ae. Aegypti egg-laying abilities when treated with extracts. Analysis of variance yielded p-values of 0.000 for egg hatching within 72 and 96 hours, highlighting significant differences across samples. These findings suggest the extracts influence mosquito reproduction, warranting further studies to assess the quality of egg hatched from larvae exposed to these treatments. The potential of botanical insecticides derived from weeds represents a promising step toward sustainable mosquito control in the fight against vector-borne diseases.

Abstract

Community Service in IoT-Based Organik Rice Farming Assistance, conducted through demonstration plots. The goal is to address productivity issues in rice farming on floodplain swamp lands. This issue can be addressed by applying a sustainable farming approach that combines technology with organic materials. The activities held with the Tunas Baru farmer group in Kotadaro Village have shown positive results. The group’s 27.5-hectare land, which had low productivity in the second season, has shown improvement due to increased soil fertility and a significant reduction in pest and disease attacks below harmful economic thresholds. The technology used in this program includes pH monitoring sensors, and NPK content sensors, among others. Additionally, the program teaches the production of soil conditioners such as biocompost, liquid Beauveria, and liquid Trichoderma. Over 83% of the farmer group members involved in the program understand the long-term benefits and the potential for increased productivity due to the adoption of sustainable farming practices with a technological approach.

Abstract

The use of pesticides is one of the control alternatives that is widely used by farmers. However, continuous and inappropriate use of pesticides can have negative impacts on humans and the environment. This research aims to determine the relationship between the level of farmer compliance in using pesticides and pest attacks, disease, natural enemy populations and product safety. The research was conducted in two areas, namely Tanjung Lago and Pemulutan by interviewing farmers and direct observation of rice fields. The variables observed were the percentage and intensity of pest attacks, plant disease. and natural enemy populations. The level of farmer compliance is connected to field data and the correlation efficiency is calculated. The relationship between farmer compliance in the use of pesticides against pests and disease is negatively correlated, and positively correlated with the population of natural enemies.  Using herbal pesticides according to the dosage can reduce the negative impact of pesticides on the environment.

Abstract

An alternative method for controlling Spodoptera frugiperda applies entomopathogenic fungi (EPF). The present research aimed to determine the impact of the endophytic EPF  on the growth and development of S. frugiperda. Twenty molecularly identified isolates of the endophytic EPF were used in seed treatments with the fungal suspension 1 × 1010 conidia.mL-1. The endophytic EPF that colonized corn leaves eaten by the neonate S. frugiperda larvae was able to significantly decrease the body weight of the larvae and pupae. The endophytic EPF could prolong the developmental time of all instar larvae and pupae.  The endophytic EPF could raise larval and pupal mortality and reduce the ability of adults to emerge from pupae,  and decrease egg laying by females.  The lowest percentage of adult emergence was observed in the adults from larvae consuming corn leaves colonized with Beauveria bassiana JaGiP and JgSPK isolates, which were 34.67% and 24%, respectively. Consequently, a reduced adult emergence could lead to a high cumulative death rate of 76% from larvae to adults. Finally, the endophytic EPFs negatively affect S. frugiperda growth and development.  B. bassiana JaGiP and JgSPK isolates are the most pathogenic fungi in inhibiting the growth and development of S. frugiperda. They are promising candidates for controlling S. frugiperda in the corn field.

Abstract

In the North Indralaya sub-district, annual crop agriculture, including annuals, melons, and watermelons, relies on conventional cultivation methods using expensive synthetic chemical fertilizers and pesticides to enhance production and combat pests and diseases. This community service initiative aims to educate and implement integrated control practices for sustainable annual crop cultivation while providing knowledge on pest and disease management in Tanjung Seteko Village, Indralaya District, Ogan Ilir Regency. The project, part of Sriwijaya University's integrated community service program, seeks to transform the village into a vegetable center in Ogan Ilir. The activities involve socializing integrated control methods through focused group discussions, practical sessions on biostimulant preparation, and field application. Farmers actively participate, posing questions about optimal annual crop cultivation and integrated control solutions. Preliminary results indicate that combining biostimulants with integrated control effectively manages pests and plant diseases. Continued intensive support aims to enable farmers in Tanjung Seteko village to adopt integrated control practices successfully, contributing to the village's potential as a vegetable center in Ogan Ilir.
