Shadila, T.A., & Jubaedah, D. (2024). Aplication of starvation and fermented feed on growth and feed conversion ratio of tilapia (Oreochromis niloticus). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 135–142). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the methods that can increase the growth of culture tilapia is by applying a combination of the starvation method and feed fermentation. The results of previous studies showed a high increase in fish growth when fish are starvated and fed fermented feed compared to the growth of fish without starvated and fed non fermented feed. The purpose of this activity was to determine the growth and feed conversion ratio of tilapia (Oreochromis niloticus) that were starvated and fed fermented feed at Kelompok Pembudidaya Ikan in Tanjung Seteko, Indralaya, Ogan Ilir. Fish rearing for 28 days. Fish stocked in 2 nets (size 0,5 m ´ 0,5 m ´ 0,65 m) that were placed in concrete pond (size 5 m ´ 4 m ´ 0,7 m). The first pond (K0) as control (without starvation and fed by commercial feed) and the second pond (K1) as treatment (starvated and fed by fermented feed). The parameters were absolute growth of weight and length, feed conversion ratio, and survival rate. Water quality measurements were temperature and pH. The results showed that absolute growth of tilapia that were starvated and fed by fermented feed were higher than those were not starvated and fed by commercial feed. Fish that starvated and fed by fermented feed produced an absolute weight growth of 7.14 g, absolute length growth of 2.34 cm, feed conversion ratio of 1.4, survival rate of 93.3%, and water quality in fish ponds were pH of 7.3-8.3 and temperature of 25.4-31.7℃.

Helbawanti, O., Widi, R.H., Rosliyati,A., & Nuraini, C. (2024). Coping strategy of maize farmers in the struggle with the selling price uncertainty and climate change. In: Octaviana H et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 477–489). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Maize farmers struggle to purchase production factors and provide for household needs due to low incomes. Middlemen dominantly determine the price of maize harvested by farmers. Limited market access and lack of post-harvest handling results in very low purchase prices by middlemen. Farmers often plant maize rather than rice because it experiences longer droughts than the rainy season. The study was conducted to analyze farmers' attitudes towards the risk of price and climate uncertainty in maize farming. The method used was an analysis of risk sources including human resources, processes, productivity, and reputation. The assessment of price and climate uncertainty used risk mapping. The results explained price uncertainty and drought at high risk level. The impact or severity of the risk of price uncertainty at a large level. The likelihood of price uncertainty was at the high level of very frequent, while drought was at the average level of frequent. The risk sources of price uncertainty and drought affected the purchasing behavior of production factors, which did not increase and tended to decrease, as well as a decrease in post-harvest handling of maize. The purchase of fertilizer and payment of labor costs reduced the profit margin of maize sales, which were subjected to pressure from middlemen who determined the purchase price. The inability to add value to maize weakens the farm household economy as farmers had no other source of income. The farming risk sources of price uncertainty and prolonged drought were sources of risk that need to be controlled.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 374–382). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Soil productivity for crops is currently decreasing, including kale, so alternative materials in the form of biosans are needed for improvement. This experiment aimed to determine the best dose of biosan (biochar and chitosan) on the growth of water spinach. This experiment used a complete randomised design (CRD). With 5 treatments and 3 replications. Treatments consisted of no biosan (B0); biosan 5 tons/ha (B1); biosan 10 tons/ha (B2); biosan 15 tons/ha (B3); biosan 20 tons/ha (B4). The parameters observed included vegetative, while the heavy metal measured was Cu. Data analysis used anova at the 5% level, and BNT test. The results showed that the treatment dose of biosan 20 tonnes/ha was the ideal dose for the growth of kale plants aged 6 weeks after planting. The average results obtained include plant height (39.12) cm, number of leaves (14.00) strands, leaf area (362.62) cm2, plant wet weight (83.72) g, plant dry weight (5.42) g and production yield of 27.91 tonnes/ha. The results of Cu heavy metal analysis showed a significant decrease in Cu. Biosan, besides being used as a soil improver, can also be used to control heavy metal Cu.

Hendarjanti, H. (2024). The incidence of ganoderma boninense basal stem rot disease: a review of knowledge, perception, and attitude of oil palm smallholders. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 958–968). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The palm oil industry has been the lifeblood of the Indonesian economy for decades. In 2023, around 40.75% of the land planted with oil palm is smallholder oil palm plantations. The expansion of oil palm causes instability in the ecosystem due to the monoculture planting system. The palm oil industry faces the problem of Basal Stem Rot (BSR) disease caused by the fungus Ganoderma boninense. This fungus can spread the disease through agents, which causes severe threats to the industry (Paterson & Lima, 2018). Smallholder oil palm plantations are also greatly affected, with the occurrence of BSR disease causing economic losses due to decreased production of fresh fruit bunches (FFB) and the death of oil palm trees. This study aimed to identify the level of knowledge, perception, and attitude of oil palm farmers towards the occurrence of BSR disease. A survey method through face-to-face interviews using a structured questionnaire was used to collect data from 110 respondents among independent smallholders in Musi Banyuasin, Ogan Komering Ilir and Muara Enim Regencies. The study showed that most independent smallholders only understood knowledge related to BSR disease after training. Smallholders need a better perception of the occurrence and management of BSR disease, which also affects smallholders' attitudes and actions in managing BSR disease. The findings of this study can be helpful for relevant authorities in identifying strategic programs to improve the knowledge and skills of oil palm smallholders in managing BSR disease.
