Yuliana, Y., Wulandari, F., Amalliah, M., Lestari, T. (2024). Indigofera cultivation in post-tin mining land. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 600–608). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The optimal availability of land for the development of forage in Indonesia is increasingly narrow. Suboptimal land in Bangka Belitung continues to increase due to tin mining activities. Indigofera as an alternative plant is cultivated on post-tin mining land for livestock use. The aimed of this research is to determine the growth and cultivation techniques of Indigofera on post-tin mining land. The research was carried out from July to September 2024. The research location was at the Kampoeng Water Reclamation land at Jangjang, Dwi Makmur Village, Merawang District, Bangka Regency. The method used in this research activity is a single randomized group design (RAK) experimental method. Randomized block design with several ameliorant treatments. The treatments used were A0 control (without treatment), A1 with the addition of cow manure, A2 with the addition of cassava peel waste and cow manure, A3 with the addition of cassava peel waste which had been turned into block compost. The results of the research showed that the growth response of indigofera was significantly different to the administration of several ameliorants. Providing cow manure provides better plant growth compared to other treatments.  The application of cow manure showed the best treatment for the parameters of plant height, number of leaves and number of stalks on indidigofera plants. Indigofera plants are recommended as animal feed on post-tin mining land.

Abstract

Low back pain (LBP) is one of the most common musculoskeletal disorders that can impair daily activities. The causes of LBP are mostly non-specific, including the abnormalities in the soft tissues or form of muscles, ligament injuries, and muscle spasms or fat igue. One of the causes of LBP is carrying excess weight. If the load carried exceeds 15% of body weight, the person who carried the weight will experience musculoskeletal disorders. Students may carry a backpack with a weight that exceeds the recommended weight and this weight will put pressures on the muscles, ligaments, and tendons, causing tension and acute neck pain. These students then will have a higher risk of suffering LBP. The aimed of this study was to identify the relationship between the backpack load and the incidence of low back pain in students. Using the cross-sectional analytical method, this study was performed on a total of 63 students from a senior high school in Cimahi, Indonesia. Subjects were selected using the multistage random sampling and data on the sociodemographic, backpack load, and low back pain were collected and analyzed using the chi-square test. Results showed that 45 students (71.4%) experienced LBP, while the average weight of the backpack carried by these students 6.59 kg (p <0.001). Thus, there is a significant relationship between the excessive backpack weight and the incidence of LBP among students.
