Karneta R, Reshi W. 2020. Characteristics of sereh wangi oil with leaf harvest age and long distillation. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xxx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Fragrant lemongrass (Cymbopogon nardus L.Rendle) is a grass plant, originally potential to prevent soil erosion and rehabilitating critical lands, it turns out that this plant contains essential oils from the leaves and stems which is very potential to be used by the pharmaceutical and cosmetic industries. This study aims to determine the effect of harvesting time and time of distillation process on the characteristics of citronella oil produced. This study used a randomized block design arranged in a factorial which consists of two factors, namely the age of harvest of fragrant lemongrass leaves (4 and 6 months) and distillation time (3,4,5,6 hours), with 8 treatment combinations, and three replications. Implementation of research on CV Alam Palindra Agro, komplek kavling Palindra Green City Indralaya Ogan Ilir. The results of the study are harvest age of 4 months of fragrant lemongrass leaves gives the best results against yield, geraniol, citronellal, specific gravity and refractive index. The distillation time was treated for 5 hours gives the best results against yield, geraniol, citronellal, specific gravity and refractive index. The interaction between harvesting age of 4 months of citronella leaves and 5 hours of distillation time give the best influence on yield, geraniol, citronellal, and specific gravity but the best refractive index at 6 months of harvest. The conclusion is harvest age 4 months and distillation 5 hours provide the best yieldand quality of lemongrass oil.

(pp. 472-481).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Achieving productivity in rice farming cannot be separated from the performance of farmer groups. The research objective is to measure the combined performance of farmer groups in increasing the productivity of rice farming. Calculating productivity and analyzing the relationship between Kelompok Tani performance and rice farming productivity. The research method is a survey method. Determination of samples using a simple random method. The results of this research based on the total score of 50.9, the performance of the farmer group is with medium criteria. Average production is 5,181 kg/year/arable area. The productivity of rice farming ranges from 1000 kg/ha to 6500 kg/ha and the average productivity is 3,455 kg/year/ha. There is a significant relationship between the performance of farmer groups and the productivity of rice farming. The performance of the rice farmer group as a vehicle for learning classes, a vehicle for collaboration and as a production unit has a score of 50.9 with medium criteria. The average productivity of rice farming is 3,455 kg/ha/year. There is a positive and significant relationship between the performance of farmer groups and productivity with a correlation coefficient value of 0.385 with the criterion of medium closeness.
