In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 826-834. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Microbial fungi are one of the main ingredients used for both practicum and research in the laboratory. The methods used in this study were experimental methods, documentation and data analysis. The treatments used were three isolates of microbial fungi, namely Aspergillus sp, Trichoderma sp and Penicillium sp as a comparison, and each replicate per isolate was carried out in five replicates which were then stored in a storage device, the observation time was carried out for five months with an interval of one month of observation. The purpose of this study was to determine the effect of storage on the growth of microbial fungi Aspgillus sp, Trichoderma sp and Penicillium sp stored in Incubators, Ice cabinet, and Germinators both in the short and long term. The results showed that the best place for fungi based on morphological texture, color, thickness of mycelium, diameter of hyphal growth and physiological fungi was stored in an incubator, we can see this based on research data where the percentage of hyphal growth is the fastest stored in the incubator, and the growth of hyphae is the fastest. the slowest being stored in the ice cabinet, not only hyphae growth, the fungal media in the incubator is more humid, the mycelium is thicker, and the color of the spores/conidia is lighter, the physiological shape of the conidia is also larger, because the nature of the media is more humid so the shelf life of mushrooms can also be higher. long. Meanwhile, the fungus stored in the germinator had good hyphal growth, but the media was easier to contaminate, the temperatur

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

Symptoms of fruitfly (Batrocera spp) attack and application of correct installation of pheromone traps in controlling fruitflies on eggplant (Solanum melongena L). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 172-179. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Eggplant (Solanum melongena L.) is one of the plants with a wide distribution because it is include in the food ingredients of daily life. Fruitflies are small insects that are one of the pests on eggplant plants. The existence of this fruitfly was usually left alone by farmers because it could help pollinate eggplant (Solanum melongena L.). This observation aimed to determined the symptoms of fruit fly attacks and determine the proper installation of pheromone traps on eggplant plants (Solanum melongena L.). This research methodology was based on a literature study of scientific articles. Symptoms of attacks caused by fruitflies were in the form of puncture marks from the ovipositor. Fruitfly attacks were found on eggplants that were almost ripe so that the impact of these attacks on eggplants becomes rotten. The use of pheromones can reduced the use of insectisides. The proper installation of pheromone traps were placed the trap at distance of ±1.5 meters. The results of the pheromone trap obtained a ratio of 3:1 in the first bottle, 1:1 in the second bottle, and 1:1. This shows that there were more male fruit flies than female fruit flies. The conclusion of this observation shows that the symptoms of fruit fly attack such as the presence of puncture marks on almost ripe fruit, then the right strategy for applying pheromone traps with a distance of ±1.5 meters

Inhibition of germination due to application of extracts from main plants and ratoon sorghum (Sorghum bicolor L.) produced in swamplands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 426-434. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Sorghum is one of the plants that produces allelopathic chemicals with bioherbicide potential. Water extract can be used to suppress weeds around planted plants. The water extract material's source has the potential to be used as a variety of bioherbicides. The goal of the study was to see if water extract of sorghum obtained from the main plant and ratoon growing in swampland with different test plants could hinder germination. A randomized block design was adopted in this investigation. The first factor is the extract's source, which is made up of the primary plant and ratoon. The second component was the test plants, which were Numbu and Suri 3 types. Experiments on Petri dishes used the bioassay method. Each petri dish received 10 mL of aqueous extract, 25 sorghum seeds, and was cultured for five days. The main plant had the largest germination inhibition, as evidenced by normal germination (33.78%), shorter radicle length (5.55 cm), and a higher number of non-growing seeds (47.12%). Furthermore, the Suri 3 variety had the maximum germination inhibition, with normal sprouts (34.65%), radicle length (5.10 cm), sprout wet weight (0.118 g), and radicle dry weight (0.118 g) in the test plant (0.0012 g). low, and seeds did not develop any faster (43.57 percent). These data suggest that the most allelopathic chemicals are produced by sorghum extract taken from the primary plant. Furthermore, the maximum inhibition was achieved using sorghum extract from the Numbu variety in combination with the Suri 3 test plant. As a result, the primary crop has the greatest potential as a bioherbicide source
