Abstract

In this study, activated cassava leaves were prepared using NaCl (CLN) and KOH (CLK) as novel and low-cost materials for removing dyes from water. The prepared materials were characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The adsorption experiments were carried out under different conditions of initial dye concentration (50 – 600 ppm), pH solution (4 – 10), and contact time (1 – 180 min) under room temperature. The adsorption kinetics has been studied using the pseudo-first and pseudo-second-order. The equilibrium isotherms have been analyzed using the Langmuir and Freundlich models. The adsorption kinetics of methylene blue onto activated cassava leaves follows a pseudo-second-order model. According to the isotherm study, the Langmuir model shows the best fitting results with the maximum adsorption capacity of 217.39 mg/g and 416.66 mg/g for cassava leaves that were activated by NaCl and KOH, respectively.

Abstract

Getih-getihan (Rivina humilis L.) plants can be used as antibacterial, antioxidant and natural pesticides. Most of the biological activities of natural products originated from secondary metabolites contained therein. Studies have shown the effects of leaves, branches, and fruits extract of R. humilis towards biological activities. However, identifying the phytochemical compounds of R. humilis L. fruit is less discussed. Here we proposed research on the identification of secondary metabolite compounds of R. humilis L. fruit extract using phytochemical screening tests and spectroscopic method. The extraction of R. humilis L. fruit was proceeded by maceration method using methanol solvent. The series of phytochemical screening tests signified the presence of alkaloids, terpenoids, tannins and flavonoids. Furthermore, we applied FT-IR analysis to confirm the existence of functional groups in the secondary metabolite compounds. A broad absorption band showed the hydroxyl groups (O-H) at 3265 cm-1. The sharp band at 1632 cm-1 exhibited the C=C stretching band. The presence of C-N (stretching) was signified by the absorption band at 1237 cm-1, while the C-H bond in CH3 terminals (alkanes, alkyl group) was exhibited at 1401 cm-1. All the functional groups confirmed in the FT-IR analysis corroborated the phytochemical test results.

Abstract

Penyakit perut seperti maag, diare, dan lain-lain bisa diatasi dengan menggunakan obat-obatan sintetis atau antibiotik, baik yang diresepkan oleh dokter maupun yang dijual bebas. Namun, obat-obatan tersebut dapat berkemungkinan memberikan efek samping pada penderita dan bahkan beberapa penyakit bisa mengalami resistensi. Penggunaan tanaman obat keluarga sebagai alternatif herbal bisa menjadi solusi karena senyawa metabolit sekundernya bermanfaat dalam pencegahan dan penyembuhan penyakit seperti sakit perut, serta sifatnya yang alami sekaligus dipercaya memiliki sifat toksik yang lebih minimal. Maka dari itu, kegiatan pengabdian tentang sosialisi tumbuhan obat keluarga sebagai obat sakit perut dan pelatihan salah satu penggunaan racikannya pada masakan dilaksanakan pada Desa Patoman, Pagelaran, Pringsewu, Lampung. Desa Patoman merupakan salah satu daerah yang memiliki tanaman-tanaman herbal. Namun, dalam hal pengolahannya, masih diperlukan peningkatan pengetahuan, salah satunya melalui pemanfaatan racikan herbal dalam masakan untuk mengurangi rasa sepat, pahit, atau rasa tidak enak lainnya. Pengenalan salah satu cara memasak makanan khas berkhasiat obat dari Aceh, khususnya dari Suku Gayo yaitu Cecah Benyet/Menet memiliki potensi yang sangat menjanjikan. Makanan tradisional Cecah Benyet/Menet berasa lezat tanpa menghilangkan khasiatnya sebagai obat sakit perut yang dibuat dengan memanfaatkan racikan sari kulit batang tanaman obat sebagai bagian dari bumbunya. Diharapkan, kegiatan pengabdian ini menumbuhkan pemahaman masyarakat tentang cara meracik tumbuhan obat, serta pemanfaatan racikan agar lebih disukai bagi pengonsumsinya.

Abstract

Calcium carbonate derived from eggshells has significant potential for use in drug delivery systems, pharmaceutical, food, catalyst, cement, and concrete industries. Although eggshell waste is non-toxic, its excessive accumulation in the environment may contribute to ecological issues. Colonizing pathogenic bacteria in unprocessed eggshell waste poses a potential health risk. The present study outlines the production of precipitated calcium carbonate (PCC) from eggshell waste through a calcination-carbonation process, offering a sustainable approach to its utilization. The calcination was carried out at 900 ºC. The carbonation process was performed in an HNO3 solution, and the NH3 solution was under-treated for 60 minutes. The results exhibited that the precipitated calcium carbonate (PCC) had a purity of 95.2% CaO. It possessed predominantly the calcite phase with a rhombohedral crystal system, as confirmed by the XRD analysis. The crystallite size of PCC was 109.5 nm, measured using the Debye-Scherrer equation. The phase composition of PCC was 99.3% calcite, 0.5% vaterite, and 0.2% aragonite. FTIR analysis further corroborated this data by showing a sharp and unsplit peak at 1419 cm-1, demonstrating the presence of a calcite phase. SEM images revealed a cubic-like morphology, a characteristic of the calcite form of calcium carbonate (CaCO3). The synthesized calcium carbonate in this study holds potential for applications in dental materials and as fillers in polymer matrices for food packaging.

Abstract

Acne vulgaris is a common skin disorder caused by clogged pores and infection by Propionibacterium acnes. The use of synthetic chemicals in skincare products often leads to side effects, highlighting the need for safer and eco-friendly natural alternatives. Natural zeolite, particularly Lampung Natural Zeolite (ZAL), has potential as an antibacterial agent due to its porous structure and adsorption capacity. This study evaluates the effectiveness of ZAL as an active ingredient in clay mask formulations against P. acnes. ZAL was activated and purified, then formulated into masks with varying concentrations (2.5 g, 5 g, and 7.5 g). Characterization was conducted using IR, XRD, and SEM, while antibacterial activity was tested using the agar diffusion method. Activation improved crystallinity and increased silanol (Si–OH) groups, enhancing antibacterial performance. The 5 g zeolite formulation showed the largest inhibition zone, indicating optimal effectiveness. Overall, ZAL demonstrates strong potential as a natural antibacterial agent for facial mask products.
