Potency of lemongrass stem extract (Cymbopogon citratus) for fish treatment from edwarsiella tarda bakteri bacteria. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 314-319. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The high demand for fishery products has resulted in cultivators implementing intensive and even super intensive cultivation systems. The intensification of fish farming is characterized by an increase in stocking density followed by an increase in the use of artificial feed which has the potential to become waste and cause disease. To overcome this, alternative actions that are safer and also effective for controlling fish diseases are needed. One alternative is to use herbal plants that are anti-bacterial. By using herbal plants, it will be safer, easier to obtain and also not pose a danger to the surrounding environment. This study aimed to determine the effectiveness of lemongrass stem extract to treat bacterial disease in fish caused by Edwarsiella tarda. Some research results showed that Cymbopogon citratus extract is rich in benefits in herbal medicine. Cymbopogon citratus extract had antibacterial properties that could inhibit the growth of pathogenic bacteria in fish. Phytochemical test results, lemongrass extract contained secondary metabolites such as alkaloids, steroids, terpenoids, phenolics or tannins or flavonoids and saponins. Based on the results of in vitro tests on lemongrass stem extract, it was able to inhibit the growth of Edwarsiella tarda bacteria where the inhibition zone formed after the media was incubated for 24 hours with a size of 21 mm. This proved that lemongrass stem extract can inhibit the growth of Edwarsiella tarda bacteria based on the results of the inhibition test

The effect of relative humidity of fermentation room on phytochemical compound content and antioxidant activity of coffee skin-derived cascara was determined in this study. Robusta coffee skin was collected from Semendo, Muara Enim district, South Sumatera. A factorial completely randomized design was used and two factors were investigated, namely relative humidity of fermentation room (80, 85, 90 and 95 percent) and serving form of product (powder and solution). All experiment was carried out in triplicates. The observed parameters included both qualitative (saponin, flavonoid, alkaloid, and tannin test) and quantitative (pH value, phenol content, tannin content and antioxidant activity (IC50)) characteristics. The resuls revealed that all samples contained saponin, flavonoid, alkaloid, and tannin, both in powdered and in cascara solution. Relative humidity of fermentation room showed significantly increased pH value, total phenol content, tannin content and increased antioxidant activity. On the other hand, serving form of product showed significantly increased pH value, decreased total phenol content and tannin content. Furthermore, interaction of the two factors showed significant effects on pH value and total phenol content. In conclusion, powdered cascara fermented in 95 per cent relative humidity was the best treatment, since it contained saponin, flavonoid, alkaloid, and tannin and hat pH of 5.84, total phenol content of 2.45 mg/g, tannin content of 3.67 mg/g and IC50 of 67,94 mg/kg

Tingkat Serangan Larva Spodoptera frugiperda (Lepidoptera: Noctuidae) pada Tanaman Jagung di Ketinggian Tempat yang Berbeda. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 563-569. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Corn (Zea mays L.) is a commodity that is widely cultivated in Indonesia. Cultivation is carried out in various areas, from the lowlands to the highlands. Cultivation of corn plants is inseparable from pest attacks, one of which is Spodoptera frugiperda (Lepidoptera: Noctuidae). The altitude of the place is not known with certainty with the influence of S. frugiperda attack. In terms of knowing the attack rate of S. frugiperda on corn was done by collecting data. Aim to find out how the effect of altitude on the level of attack S. frugiperda. From the results of the literature study showed that at altitude 1000 masl, the attack was categorized as high with a certain temperature range. The attack rate of S. frugiperda was also known to be influenced by climate and the presence of natural enemies in the ecosystem. So, it can be concluded that altitude didn't absolutely affect the attack of S. frugiperda on maize
OLERIKULTUR URBAN: Kontribusi untuk Meningkatkan Produksi Pangan Nabati untuk Masyarakat Perkotaan

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 1-10. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Population increase directly affects food demand. Since the increase will be concentrated in urban area, this trend should be appropriately responded by intensifying urban agriculture activities. Urban agriculture characterized with limited availability of agricultural land but better infrastructure than rural area. Urban dwellers are also more prepared to adopt advanced agricultural technology and have better access to financial sources. Technology-wise, hydroponics and vertical agriculture have been practiced by urban farmers. Besides for food production, urban agriculture gives other benefits, including aesthetics and better quality of local environment. In major city, green wall and green roof have been developed at tall buildings. Vegetables and ornamental plants are the most commonly used in urban area. In some developed countries, indoor vegetable cultivation has been practiced using artificial lightings and large scale plant factories had employed automation system using artificial intelligence technology. Regardless of rapid development on agricultural technology, the selected technology for local application should consider availability of local natural resources and financial capacity of native farmers. Intensification of urban and peri-urban agricultural activities is not expected to fully meet total urban food demand. Therefore, conventional agriculture in rural area is still strongly needed
