Abstract

ABSTRAK Telah dilakukan sintesis membran polistirena sulfonat (PSS)-kitosan dari modifikasi limbah styrofoam, kemudian dipelajari kemampuannya dalam mengadsorpsi logam Ni(II) dan Cu(II). Telah ditentukan pula komposisi optimum PSS-kitosan, uji stabilitas asam basa, dan kemampuan swellingnya. Parameter kajian adsorpsi yang dipelajari dalam penelitian ini meliputi pH optimum, kinetika adsorpsi, isoterm adsorpsi, pengaruh kation lain secara selektifitas, dan penentuan mekanisme adsorpsi. Analisis logam Cu(II) dan Ni(II) sebelum dan sesudah proses adsorpsi dilakukan dengan menggunakan metode Spektrofotometri Serapan Atom (SSA) Hasil penelitian menunjukkan bahwa polistirena sulfonat (PSS) berhasil diperoleh dari reaksi sulfonasi limbah styrofoam yang ditunjukan dengan spektra FTIR. Komposisi optimum membran PSS:kitosan untuk mengadsorpsi logam Cu(II) dan Ni(II) adalah perbandingan 60:40 dengan kestabilan, sifat fisik, dan kemampuan adsorpsi yang paling baik. Keadaan pH optimum adsorpsi logam Cu(II) dan Ni(II) berada pada pH 5, waktu optimum berturut-turut 45 menit dan 60 menit, serta konsentrasi optimum berturut-turut 60 ppm dan 40 ppm. Model kinetika dan isoterm adsorpsi logam Cu(II) dan Ni(II) pada membran PSS-kitosan adalah orde kedua semu (McKay dan Ho) dan model isoterm Freundlich. Tetapan laju reaksi logam Cu(II) dan Ni(II) pada pH 5 berturut-turut 0,480 mmol/g-1menit-1 dan 0,423 mmol/g-1menit-1. Adanya logam Ni(II) dalam adsorpsi Cu(II) tidak memberikan pengaruh yang signifikan sampai pada perbandingan Ni(II)/Cu(II)= 2:1, namun sebaliknya dengan kehadiran logam Cu(II) pada adsorpsi logam Ni(II) sudah memberikan pengaruh pada perbandingan Ni(II)/Cu(II)=1:1. Afinitas membran PSS-kitosan terhadap logam adalah Cu(II) > Ni(II). Pada studi desorpsi diketahui jenis interaksi antara adsorbat dan situs aktif adsorben merupakan mekanisme pembentukan kompleks, pemerangkapan dan pembentukan ikatan hidrogen. ABSTRACT Synthesis of polystyrene sulphonate (PSS) – chitosan membrane of styrofoam waste modification and its ability to adsorb Ni (II) and Cu (II) metals has been studied. The optimum composition of PSS-chitosan, acidity stability test, and swelling ability have been determined. The parameters of the adsorption study studied in this study include optimum pH, adsorption kinetics, adsorption isotherms, selective cationic effects, and determination of adsorption mechanisms. Analysis of Cu (II) and Ni (II) metals before and after the adsorption process was performed using Atomic Absorption Spectrophotometric (AAS) The results showed that polystyrene sulphonate (PSS) was obtained from the sulfonation of styrofoam waste using the FTIR spectra. The optimum composition of rasio PSS: chitosan membrane for adsorbing Cu (II) and Ni (II) is 60:40 with the best stability, physical properties, and adsorption capability. The optimum pH adsorption of Cu (II) and Ni (II) metals was at pH 5, the optimum time was 45 min and 60 min, and the optimum concentrations were 60 ppm and 40 ppm. The kinetic and adsorption models of Cu (II) and Ni (II) metals on PSS-chitosan membranes are second-order (McKay and Ho) and Freundlich isotherm model. The reaction rates of Cu (II) and Ni (II) reactions at pH 5 were 0.480 mmol / g-1menit-1 and 0.423 mmol / g-1menit-1. The presence of Ni (II) metal in Cu (II) adsorption did not give a significant effect to the ratio of Ni (II) / Cu (II) = 2: 1, but with the presence of Cu (II) metal on metal adsorption Ni (II) have an effect on the ratio of Ni (II) / Cu (II) = 1: 1. The affinity of PSS-chitosan membrane to metal is Cu (II)> Ni (II). Sequential desorption studies showed that the adsorption of Cu (II) and Ni (II) metals on the PSS-chitosan membrane were estimated to follow a complex formation, hydrogen bond formation, and physical entrapment mechanisms.

Abstract

Aromatherapy is an alternative treatment method that utilizes essential oils and volatile components, such as terpenes and aromatic compounds. The active compounds of keruing oleoresin are phthalic acid, namely phthalic acid di(3-methoxybenzyl) ester and phthalic acid, 5-ethyl-1,3-dioxan-5-yl octyl ester causing keruing oleoresin to have a distinctive fragrance. The purpose of this study was to formulate keruing oleoresin in aromatherapy candle preparations. This research method includes base optimization, formulation of keruing oleoresin aromatherapy candles with concentrations of 0%; 2.5%; 5%; 7.5%; and 10%, and evaluation of aromatherapy candles including organoleptic testing, melting point, and burning time. The results of organoleptic testing of aromatherapy candles in shape, aroma, and color showed that F4 with 10% oleoresin concentration had a more dominant aroma and color. Melting point and burning time tests showed F1 with a concentration of 2.5% had a higher melting point of 54.6°C and a longer burning time of 144 minutes.

Abstract

One of the natural ingredients that can be used as a cosmetic ingredient is miana leaf (Coleus scutelleroides (L) Benth) which contains flavonoid compounds with antioxidant activity that can be used for skin care. These compounds can prevent free radicals that can cause premature aging. The extraction method was used in this study with 96% ethanol solvent and continued with the fractionation process. The determination of antioxidant activity was determined by calculating the IC50 value where the IC50 value of the ethyl acetate fraction of miana leaves obtained was 27.90 ppm. In the study, a formulation of face mask cream preparations with a variety of active ingredients (0,6; 1,2; 2,4). Evaluation of the preparation was carried out on the physical quality of face mask cream using the cycling test method. Based on the results of stability tests on the four preparations, formula 2 with 1.2 g of active ingredients shows the best formula. Antioxidant testing from F1, F2 and F3 obtained IC50 values of 96.33 ppm, 82.73 ppm, 72.71 ppm. The statistical test of antioxidant activity showed a p<0.05 result which indicates that there is a significant difference between the three formulas. Cycling test showed that the facial mask cream preparation was physically and chemically stable. There was no significant change in color, odor, texture, phase separation, or pH change. Viscosity also remained stable, indicating good shelf life during normal storage.
