The relationship of farmers' education level to pest and disease attacks in plant cultivation in South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 787–798). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The aimed of this research was to determine the behavior and understanding of farmers in using pesticides based on educational background. Pesticide is a poisonous chemical which is able to ruin human and animal health and also pollute the environment. The use of pesticide has to consider five properness i. e. proper target, proper active ingredient, proper time, proper dosage/concentration and proper equipment. Knowledge is one of factors affecting people behavior, including behavior in pesticide application. The less knowledge of farmers in pesticide application made them use too much pesticide which might cause degradation of environment and pesticide residue in agricultural products which is dangerous to consumers. Method applied in the study was an interview method using questionnaire to 180 farmers, followed by field observation in their field. 57% of respondents had Elementary School background, 20% had Junior High Scholl background, 23% had Senior High School background and one of them had university education background. The average score of pesticide use was 1,92 from farmers who graduated from bachelor, then the pesticide score of farmers who graduated from elementry school, junior high school, and high school had the same pesticide score of 2,39 and all education is categorized as good in using pesticides. The pesticide application score did not correlate with the presence of pest in the field but significanly correlate with the prsence of plant diseases. The highest plant disease intensity (26.55) was found in the farms belonged to farmers with elementary school backfround, while the lowest (6.61) was found in the field of farmer with university educational background.

Prayitno, C. H., & Setiadi, D. (2024). The utilization of limestone post-mine land as an alternative forages producing land for ruminants. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 11–19). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Post-limestone mining land is widespread throughout Indonesia and causes negative impact in the form of abandoned open lands. The availability of land for forage is very limited, so it is necessary to use the abandoned land such as post-limestone mining land as an alternative forage producing land. Utilizing post-limestone mining land as a producer of forage also contributes to reduce ecosystem damages. Low soil fertility and the type of forages to be cultivated are challenges in making post-limestone mining land as an alternative forage producing land. The innovations to utilize post-limestone mining land are improving the quality and fertility of the soil with organic matter, revegetating legume plants as pioneer plants, and planting cultivated grass and sweet potatoes as an effort to fulfill the forages for ruminant animals.

Nisa, I. F., Nadifah, U., Mentari, A. (2024). Utilization of anthocyanin compound in rosella flower extract (Hibiscus sabdariffah) as a natural formalin detector in tofu. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp.255–261). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Rosella (Hibiscus sabdariffah) is one of the herbal plants that contains anthocyanin compounds and can react with formalin which is acidic, causing significant color changes. This study aimed to utilize anthocyanin compounds in rosella flower extract as a natural detector of formalin content in tofu. To achieve this goal, this study used an experimental method with a qualitative approach. Tofu samples were obtained from several traders in the market around Teluk Gelam Subdistrict, Ogan Komering Ilir Regency. Preparation of rosella flower extract was carried out using maceration method with 70% ethanol solvent. The rosella flower extract was then dripped on tofu samples and observed for color changes. The observation data were analyzed descriptively qualitative. The results showed that rosella flower extract was effective in detecting formalin content in tofu. The best treatment was obtained at a concentration of 5 ml rosella extract + 20 ml distilled water (P3) which produced a clear color change in the tofu. Tofu containing formalin will change color to a solid red, while tofu that does not contain formalin does not show significant color changes. Thus, rosella flower extract can be utilized as a natural detector of formalin content in tofu.
