The effect of intercropping chili with cabbage on pests and plant disease in Kerinjing Village Pagar Alam city. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp.101-113. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red chili (Capsicum annuum) belongs to the family Solanaceae and is one of the vegetable commodities that has many benefits, high economic value. The aim of this field practice is to find out the difference in intensity of pest and disease attacks on intercropping and monoculture chili plants. This field practice was carried out in Kerinjing Village, Dempo Utara District, Kota Pagar Alam, South Sumatra. The reseach uses the case method by deliberate sampling in a field by counting the number of mounds in the field and determining the sample on the mound to be observed. On the two fields that were observed were found pests and diseases that attacked the chili plants namely mandibular pests and curly diseases, yellow disease and leaf spot disease. The average intensity of mandibular pest attacks on monocultures is 2.7% while on intercropping is 11.12%. The mean intensity of attacks of curly diseases was 33.87% in monocultures and 22.35 in intercropping. In jaundice, the mean intensity of attack was 14.87% in monoculture land and 8.25% in intercropping land while the mean intensity of spotting was 5.67% in monoculture land and 1.30% in intercropping land. From the observations that have been made that there is no significant difference between monoculture land and intercropping land for pests and diseases of chili plants. Weather affects the attack of pests and diseases on both fields, where dry weather affects the spread of disease-causing vectors so that the intensity of the attacks is higher. And also the use of crop rotation that is not right also exacerbates the level of pest and disease attacks on chili plants.

Sutarma FA, Rhomadon AG, Asrul MR, Fitriyani D, Rahma FA, Anggraini HL, Umayah A, Gunawan B, Arsi A.  2022. Inventory and identification of ladybug (coleoptera: coccinellidae) on solanaceae crops in Ogan Ilir Regency, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 450-457. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The ladybug (Coleoptera: Coccinellidae) is considered to have an influence on the cultivation of solanaceae crops because there are many types as biological control agents for plant pests and as phytophagous insects. The purpose of this study was to determine the types of ladybugs on Solanacae crops in Ogan Ilir Regency, South Sumatra, Indonesia. The sampling method used 2 techniques with insect nets swinging infinity on the plant canopy and direct collection techniques, namely taking directly by hand. Sampling of the ladybug in the field was carried out 3 times in each field. Sampling of the ladybug was carried out in the morning at around 07.00-10.00 am. Based on the results of sampling in the field, the beetles found were Coccinella sexmaculata, Verania discolor, V. lineata, C. repanda, and Epilachna admirabilis. This ladybug has different morphological characteristics, body size, and distribution between predatory ladybugs and phytophagous ladybugs. The species of ladybug that acts as a natural enemy is most commonly found in chili plantations. The predatory ladybug can control the attack of A. gossypii on eggplant and chili plantations. Coccinellidae phytophagous is a plant-eating ladybug that is commonly found in eggplant plantations. The conclusion in this observation is that there are 5 species of ladybug, 4 predatory ladybugs and 1 phytophagous ladybug. Research related to the identification and inventory of the ladybug (Coleoptera: Coccinellidae) needs to be improved as information on the types of ladybug species is useful in the management of solanaceae cultivation in order to further increase solanaceae crop yields in Ogan Ilir Regency.

Santoso A, Bustommi A, Setiawan IT, Rahayu RI, Miranda RD, Sembiring RS, Umayah A, Gunawan B, Arsi A. 2022. Population of fruit flies besides using methyl eugenol on chili plants in Ogan Ilir Regency, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 120-128. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The attack of fruit flies (Bactrocera spp.) on red chili plants is one of the important problems in the red chili production process. In general, farmers still choose to use synthetic pesticides in controlling fruit flies. However, this control method has a negative impact, namely it can cause resistance and resurgence of the target pest. This review aimed to provide information about the benefits of compounds through bioattractants combined through the application of attractant traps in controlling fruit flies. This writing method uses a literature study which is analyzed and developed into an easy-to-understand review. Extraction contains methyl eugenol reaching 70-96%. The liquid compound methyl eugenol can be an attraction for male fruit flies. The trap attractant system has the ability to stimulate the interest of fruit flies and can be used for a long time. The application of trap attractants causes sexual communication disorders so that mating disorders occur in fruit flies. The conclusion obtained from the writing of this scientific paper is that the methyl eugenol compound in chili plants can be used as a control system.

Istiqomah H, Abbellia D, Triani L, Mevika N, Khodijah SS, Yuliana Y, Umayah A, Gunawan B, Arsi A. 2022. inventory and identification of rice predator insects in Ogan Ilir District, South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 552-561. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Rice (Oryza sativa) is one of the plants that is an important commodity in Indonesia, various efforts have been made to increase rice production, but often encounter obstacles, one of which is the presence of organismal pests, especially insects. Therefore, it’s necessary to have the role of natural enemies in the form of predatory insects in controlling rice pests. This study aimed to determine the number and types of predatory insects found in rice plants in three villages, namely Muara Penimbung Village, Tanjung Sejaro Village, Sakatiga Village, Indralaya District, Ogan Ilir Regency, South Sumatra. This research method was carried out by observing and using yellow traps installed in the rice fields to catch predatory insects. From the research results in the three villages, there are predatory insects with four different orders, namely the order Odonata, order Coleoptera, order Hemiptera, and order Diptera. The order Odonata (dragonfly) consists of 4 species: Pantala flavescents, Orthetrum sabina, Agriocnemis minima, Orthetrum Chrysis. Then the order Coleoptera (beetle) found consisted of 4 species: Epilachna admirabilis, Paederus fuscipes, Micraspis discolor, Diekeana admirabilis. order Hemiptera found 1 species, namely: Andrallus spinidens. One species of the order Diptera, namely: Asilidae sp. So, it can be concluded that predatory insects on rice plants are very diverse and consist of various orders that can be used as natural enemies to control insect pests or plant pests. Further education is needed about the important role of predatory insects as natural enemies of plant pest control.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 504-512. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The increase in the demand for eggplant production is not accompanied by an increase in the amount of production, which is caused by the low productivity of eggplant due to insect pests attack. This study aimed to determine the intensity of insect pests on eggplant in Ogan Ilir Regency, South Sumatra. The method used is a survey or observation in the field to observe the species of insect pests, symptoms, and the intensity of insect pests by taking 20 random plant samples (random sampling). This research was conducted on three fields with different locations. Insect pests found included mealybug (Planococcus citri), whitefly (Bemisia tabaci), leafhopper (Empoasca fabae), ladybug (Epilachna sparsa), weevil (Hypomeces squamosus), and tobacco cutworm (Spodoptera litura). Symptoms of the dominant pest attack in the form of hollow leaves caused by Spodoptera litura larvae. The level of damage from S. litura occured in the vegetative phase where the larvae eat young leaves. The data obtained were analyzed by One-Way ANOVA followed by the Honest Significant Difference (HSD) test at the 5% level. The results showed that the highest attack intensity of Spodoptera litura was in Timbangan Village (26.8 ± 1.92)% so that the attack rate could be categorized as high. The intensity of attacks in Permata Baru Village is (15.6 ± 2.70)% and the attack rate is categorized as medium. The smallest attack intensity was in Tanjung Pering Village (8.4 ± 12.07)% so that the attack rate was categorized as low.

Indayani I, Pulungan AS, Prasatya D, Miranda M, Mardiyah NU, Ramadhani CS, Umayah A, Gunawan B, Arsi A. 2022. Inventory and identification of mites on roses in Ogan Ilir District, South Sumatra Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 751-758. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Roses are widely cultivated by the public because of their beautiful and beautiful appearance as well as their fragrant and distinctive aroma, so they are nicknamed the queen of flowers, but on the other hand, roses are easily attacked by various species of mites. This study aimed to determine the species of mites on roses so that this research can make it easier to recognize and overcome the symptoms of mite attacks on roses. This research was conducted in the villages of Timbangan, Palem Raya, Sembabu Island, and Tanjung Sejaro, North Indralaya District, Ogan Ilir Regency, South Sumatra Province using survey and sampling methods. The results of the study have obtained 2 species of mites with the genus Tetranychus spp. The spread of mites occurs rapidly due to wind and human activities. Mites are polyphagous, so the possibility of expanding the host due to this pest should be watched out for. Mites attack can cause the process of formation of leaves and stems to be hampered so that the productivity of ornamental plants decreases. The mites damage the plant by sucking the liquid from the leaf cells which results in pale spots due to the damaged epidermal cells due to being sucked in. Although the individual damage caused by mites is small, with a population of thousands of mites attacking plants, it will cause more injuries so that it can reduce the photosynthetic ability of plants. So, roses are plants that are liked by many people but are often attacked by mites. It is better if the rose has been attacked by mites to minimize the spread of the attack, it is expected to spray pesticide liquid, rely on natural enemies, and plant high-yielding varieties.
