Abstract

Overburden (the dumping of mine tailings and other reject materials) from the Warukin geological formation is one of the potential acid-forming (PAF) of 33.17%. Mining can cause overburden to be exposed and affect biotic and abiotic conditions. The study aimed to analyze the biotic and abiotic factors of three different age overburdens from the Warukin Formation, South Kalimantan. Biotic factor measurements included vegetation sampling using line transect, soil insects using pitfall traps, and microbial using total plate count. Abiotic factor measurements included air temperature and humidity, light intensity, temperature, moisture, and pH of the substrate (n=3), and chemical overburden. Identification of plants and insect species using information from locals, identification books, and websites. Plant species diversity was analyzed using the Shannon-Wiener Index. Dominance species were analyzed using the Important Value Index (IVI). The relation of overburden age on biotic and abiotic factors was analyzed multivariate with Non-Metric Multidimensional Scaling (NMDS). The results showed that there are 102 species of plants and 11 species of soil insects. The numbers of fungi and bacteria are 10-4 CFU g-1 and 10-3 CFU g-1, respectively. Plant species diversity is classified as medium (H'= 2.34; 2.50 and 2.82). Changes in plant composition occurred as the microclimate and substrate nutrition improved. The organic matter increased over time. Humidity and light intensity influence the presence and composition of organisms, while pH values affect the adaptability of plants, insects, and microbes. Heavy metal concentrations have increased due to the physicochemical properties of the Warukin formation overburden.

Abstract

Abstrak Pelatihan Program Komposter Ramah Lingkungan (KRL) telah sukses diimplementasikan di SD Islam Plus Al-Azhar sebagai bagian dari inisiatif pengabdian masyarakat untuk mendaur ulang sampah menjadi pupuk melalui proses pengomposan. Melalui metode Aset Based Comunnity Development (ABCD). Pelaksanaan kegiatan ini dirancang untuk mengevaluasi efektivitas pelatihan dalam meningkatkan pemahaman siswa mengenai pengolahan sampah organik. Hasil pelaksanaan kegiatan ini sekolah sukses praktik melakukan pengomposan yang dapat digunakan untuk mengurangi jumlah sampah organik yang dibuang ke tempat pembuangan akhir. Hal ini tidak hanya menghemat pupuk secara ekonomi, tetapi juga meningkatkan kesadaran siswa tentang siklus alam dan kelestarian lingkungan.

Abstract

Tridax procumbens L. has quite high flavonoid content (6.51%). Flavonoids have antimicrobial effects that can fight bacteria. Besides that, the flavonoid content of T. procumbens leaves as an analgesic inhibits has the potential to be used as an analgesic ointment material for open wounds. Betel lime (CaCO3) also helps speed up the healing of open wounds. This research aims to optimize a mixture of T. procumbens leaves and betel lime to make a material-based herbal ointment that effective in healing open wounds. This research uses quantitative and qualitative approaches. The dependent variables used are the results of FTIR characterization, SEM-EDX, and antibacterial tests. Research results show that the 1:1 ointment sample has the highest homogeneity with an average particle size distribution of 11.95 nm. The weight and total atomic weight of carbon and calcium elements fluctuated with increasing leaf extract concentration, but the 2:1 ointment sample showed a higher calcium element content than the other samples because the amount of whiting was greater than the leaf extract. Flavonoid functional groups were successfully detected, O-H, C-H, and C-O-C. In S. aureus, it was shown that the 1:1 ointment sample was able to inhibit bacterial growth with an inhibition zone diameter of 0.062 to 1.510 cm. In addition, the contents of stigmasterol, β-sitosterol, and n-hexadecanoid acid are the main components that play a role in the inhibitory activity of bacteria. Keywords: Analgesic ointment, flavonoids, open wounds
