Daun ketepeng cina (Cassia alata) adalah salah satu tumbuhan obat tradisional untuk pengobatan penyakit kulit (panu, kadas, kurap). Hal ini juga telah ditunjang dengan informasi ilmiah yang memadai. Penggunaan daun ketepeng cina (C alata) secara tradisional dengan cara menggosokkan langsung pada bagian kulit yang diobati, namun hal ini tidak efektif karena daun yang bersifat kasar dan sedikit mengandung air sehingga sulit keluar senyawa bioaktifnya. Untuk itu perlu diperkenalkan kepada masyarakat khususnya masyarakat desa Tanjung Pering Indralaya Utara tentang pembuatan krim obat kulit dari daun ketepeng cina. Kegiatan ini diharapkan dapat menambah pengetahuan masyarakat tentang pembuatan sediaan obat kulit. Kegiatan Pengabdian ini dilakukan dengan memberikan informasi ilmiah khasiat daun C. alata dan edukasi pembuatan sediaan daun ketepeng cina dalam bentuk sediaan krim. Hasil kegiatan ini menunjukkan masyarakat secara umum telah mengenal daun ketepeng cina untuk obat kulit. Kegiatan ini telah menambah wawasan dan pengetahuan masyarakat dalam hal bentuk sediaan daun ketepeng cina untuk obat kulit, dan dapat membuatnya sendiri. Masyarakat menyadari pentingnya hidup sehat dan bersih serta pembuatan sediaan ini sangat mudah untuk dilakukan di skala rumah tangga. Kegiatan ini sangat bermanfaat bagi masyarakat terutama dalam mengatasi masalah kesehatannya yang berkaitan dengan penyakit kulit.

Cr(III) is one of the most stable chromium species in nature, Cr(III) species are not carcinogenic to humans, but if the levels in the body exceed 0.2 mg / day it is very dangerous for the body especially in the respiratory tract. The presence of chromium in the aquatic environment is so low that it is very difficult to detect it using instruments with various limitations to detect it, therefore preconcentration techniques are carried out to overcome the issue. In this study the water sample was adjusted pH using HNO3 0.1 M or NaOH 0.1 M, after which it was passed in the dowex column 50WX2-200. Furthermore, an elution process was carried out using the 1 M HNO3 eluent, the eluat was measured for absorbance with flame AAS. The results of Cr(III) preconcentration optimization are: resin weight 0.5 g, HNO3 eluent concentration 1 M, solution pH 3 and sample volume 50 – 100 mL. The Cr(III) preconcentration technique using Dowex 50WX2-200 resin has been applied to river water samples with a detectable concentration of 0.0075 mg/L.

The speciation of Fe2+ and Fe3+ iron ions using the concentration cell potentiometric method has been developed. The determination and speciation of metals that have been used include potentiometry using comparison electrodes, selective ion electrodes, and voltammetry. The concentration cell potentiometric method has the advantages of simple equipment, the use of common metal electrodes, high selectivity, and relatively low detection limits. The method validation results for Fe2+ and Fe3+ ion speciation were LOD: Fe2+ 0.22 mg/L Fe3+ 0.29, LOQ: Fe2+ 0,92 mg/L ; Fe3+ 0,01 mg/L, precision (1.17%; 1.2%) and accuracy (95.57%; 93.15%) based on CV Horwtz. This method has been well applied for Fe2+ and Fe3+ speciation in natural water samples. The concentrations of Fe2+ and Fe3+ species in Sekanak river water were (1.88 mg/L; 2.07 mg/L). Concentration of Fe2+ and Fe3+ species in well water samples (0.5 mg/L; 1.32 mg/L).

The aim of this research is to determine the effect of bentonite-Titanium dioxide (Benonite-TiO2) composite on the degradation process of methylene blue. It was carried out by synthesizing the composite through the impregnation of Titanium dioxide (TiO2) on bentonite and then characterizing the obtained compound using XRD and SEM-EDX. The results of the XRD characterization showed that there was a shift in the diffraction angle (2θ), which indicated the success of the impregnation procedure. The morphology of the composite showed that the bentonite surface had been filled with TiO2, as evidenced by the results of the EDX analysis, which showed a 7.03% increase in Titanium. Furthermore, the degradation process was carried out using various variables, including contact time, the ratio of composite weight to dye, and by irradiation with a UV lamp at a wavelength of 352 nm UV. It was discovered that the best degradation in the concentration of methylene blue occurred at a maximum contact time of 90 minutes and at a maximum weight of 10 mg of benonite-TiO2, with an effectiveness of 99.91% after irradiation and 92.26% without irradiation.
