(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Flower visitor insects play an important role, especially in pollination process of plants. The success of crop production depends largely on the success of  pollination process. The research objective was to study the role and behavior of flower-visiting insects in watermelons. The research was conducted at a fruit planting center in Indralaya Indah Village, Indralaya District, Ogan Ilir Regency, South Sumatra from June to August 2019. The study was conducted using purposive sampling method (selecting flowering watermelon plants) and observing insect behavior by using scan sampling (direct observation in the field) in the morning. The results of  observations obtained 4 orders, 8 families and 11 species. The insect orders found were Hymenoptera (4 families, 7 species), Lepidoptera (2 families, 2 species), Coleoptera (1 family, 2 species) and Diptera (1 family, 1 species). The order Hymenoptera dominates the flower-visiting insects with a role as a pollinator.

Gustiar F, Munandar M, Aprilia NR, Hasmeda M, Amar M, Arsi A. 2021. Growth and Yield of Spinach (Amaranthus sp) in various compositions of Alternative Nutrients to replace AB Mix with Hydroponic System.  In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 931-940 . Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). The high cost of AB Mix hydroponic nutrients, so there is a need for alternative growth nutrients that are cheaper and easily available. Aim of this research was to determine the hydroponic nutrition substitute for AB mix for the growth of spinach (Amaranthus sp). This study used a completely randomized design (CRD) method with four hydroponic nutrition treatments with different ingredients. The treatments given were AB mix fertilizer, NPK-based nutrition, single fertilizer-based nutrition, and organic nutrients. hydroponic nutrient constituents are calculated based on the needs of leaf vegetable plants. Needs Parameters observed were plant height (cm), number of leaves, leaf greenery level, leaf area (cm2), root volume (ml3), plant fresh weight (g), plant dry weight (g), and nitrogen concentration (N) at leaf. Based on the observation of growth parameters, AB mix nutrition treatment showed the best results. However, the fresh weight parameter of the single fertilizer-based nutrient treatment showed results that were not significantly different from the ABmix treatment. In addition to providing the highest yield, the lowest cost requirement is 1 liter of concentrate at a cost of 44,302 IDR so that single fertilizer-based hydroponic nutrients can be recommended as an alternative to AB Mix nutrition.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 329-337. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Maize is a plant that contains high carbohydrates and is one of the staple foods after rice. At the beginning of 2019, corn farmers in Indonesia had to face a new problem, namely the reduction of maize yields due to the attack of the Spodoptera frugiperda pest. S. frugiperda attack cause economic losses. In this case, proper control is needed so that these pests will not cause massive losses. One of them is controlled by using predatory arthropods. For this reason, it is necessary to carry out an inventory of predatory arthropods in corn plantations. This paper aimed to identified predatory arthropod species to controlled S. frugiperda pests in maize plantations. The methodology was carried out by literature review of journals and related articles. The predator found in the maize crop were from the Formicidae family. The species found were Camponatus sp, Camponatus sericeus, Pheidole sp, Oecophylla langinoda, Branchyponnera sennaarenis, megaponera sp, Pheidole megachepala. Other arthropods spesies found were Chrysoperla externa, Ceraeochrysa cubana, Pheidole megacephala (Hymenoptera: Formicidae), Haematochares obscuripennis, and Peprius nodulipes (Hemiptera: Reduviidae). Thus, the amount of spesies have been found were 3 species of predatory arthropods from the order Neuroptera, 1 species from the order Mantodea, 3 species from the order Dermaptera, 10 species from the order Hymenoptera, 3 species from the order Coleoptera, 1 species from the order Hemiptera, 1 species from the order Diptera and 2 species have been found. of the order Araneae.

Weight of spodoptera litura larvae and chili leaf area eaten after treated with some entomopathogenic fungal isolates. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Spodoptera litura is one of the important insect pests on chili in Indonesia that attacks the vegetative and generative phases. This study aimed to observe the effect of the entomopathogenic fungal isolates explored from the low and highlands on the decrease in feed and weight of S. litura larvae. The experiment was arranged in a Randomized Block  Design (RBD) with 52 treatments consisted of 29 isolate of Beauveria bassiana and  23 isolate of  Metarhizium spp. applied on  25  second instar of  S. litura  per replicate. The results showed that the body weight of larvae applied to B. bassiana isolates on the first day of observation was significantly different from the control. The body weight of larvae on the first day of observation of BJgTs isolates (0.30 g) and Bby (0.31 g) was significantly different and lower than the other treatments. The body weight of larvae applied isolate Metarhizium spp. significantly different from the controls. The body weight of larvae on the 9 day applied isolates MPdMs2 (4.74) and MKbTp2 (4.63) was significantly different from other treatments, the leaf area eaten was significantly different from the 7 day to the 12 day of observation. From this research, it can be concluded that B. bassiana isolates coded BJgTs and Bby, isolates Metarhizium spp. MPdMs2 and MKbTp2 codes are isolates that have an effect on reducing feed and larvae weight and cause changes in behavior of S. litura larvae.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The cultivation of vegetable crops is very much practiced by farmers both in the highlands and in the lowlands. In the cultivation of vegetables, pests and diseases cannot be separated. Pests that attack cucumber plants can be detrimental both in quality and quantity. The purpose of this study was to determine the insect pests that attack cucumber plants. Observations were made by comparing 2 cucumber fields. The comparison of the 2 fields was then carried out using the t test method. The results of observations on cucumber plants in the field were 4 species of insect pests that attack cucumber plants. Insects that attack cucumber plants consist of Diaphania sp., Aulacophora similis, Bemisia tabaci and Liriomyza sp.. The population of insect pests was found only 3 species based on visual observation and the intensity of pest attacks on cucumber plants was found to be 4 species of insect pests that attack these plants. In the t test results on insect populations, the species of Bemisia tabaci were significantly different in land 1 and land 2, while Diaphania sp. And A. Similis is not real different. The intensity of insect pests of Diaphania sp., Aulacophora similis and Liriomyza sp. Unreal different. However, the intensity of the Bemisia Tabaci attack was significantly different. The intensity of insect pests attack on land 1 was 44.76%, while on land 2 was 42.97%. Cultivation of cucumber with technical culture affects insect pests and the intensity of pest attacks.

Vanderi AR, Arsi A, Utami M, Bintang A, Amanda DS, Sakinah AN, Malini R. 2021. The role of insects to support sustainable agriculture systems. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 249-259. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Insects have the highest number of species among other living things. The understanding that insects are plant-disturbing organisms (OPT) has led to the development of synthetic chemical pesticides that are very damaging to the environment. In fact, insects have many roles to support sustainable agricultural systems. This article aimed to study the role of insects in supporting a sustainable agriculture system. This article was compiled from a study of scientific literature. It has been resulted that the review shows the success of a sustainable agricultural system can be done by utilizing the roles of insects. Such as the role of insects as pollinators of the order Hymenoptera, Lepidoptera and Diptera, and also the role of insects as decomposers of the order Hymenoptera. Then, the role of insects as bioindicators of the orders Hemiptera, Coleoptera, Ephemeroptera, Trichoptera, and Odanata. As well as the role of insects as parasitoids of the order Hymenoptera, and the role of insects as predators of the orders Coleoptera, Hemiptera, and Odonata. The conclusion, the insects do not always have a negative impact, because some of the roles of insects can be utilized to support sustainable agricultural systems.

Efficiency of the beetle menochilus sexmaculatus as natural enemy of whitefly on  chili plants (Capsicum annum L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 134-141. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Whitefly is a serious pest on chili (Capsicum annuum L.) that can cause direct damage to plants or be a carrier of viral diseases. Whitefly is an important pest found in various horticultural crops including chili..This article to knowing the role of Menochilus sexmaculatus as a predator of the whitefly pest (Bemisia tabaci) on chili plants. This article was compiled from various literature studies Menochilus sexmaculatus is a whitefly predator, its presence as a predator on agricultural land is considered to have a high ability to adapt to the environment and has a greater ability to scatter than other types of natural enemies. The predatory species Menochilus sexmaculatus worked well in controlling whitefly populations on chili plants. Menochilus sexmaculatus can prey on 200-400 whitefly nymphs per day. Suppression of whitefly populations is very useful in suppressing the occurrence of jaundice by the gemini virus. The conclusion use of Menochilus sexmaculatus as a predator has been proven to reduce whitefly populations, especially during the rainy season.

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.

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.
