ABSTRAK
Prevalensi kasus jerawat (acne vulgaris) 75-85% pada orang dewasa, terutama pada usia remaja, dan sering menjadi kronis. Etiopatologis jerawat multi-faktorial, antara lain disebabkan oleh stres oksidatif dan pengaruh hormon serta pola makan. Tujuan dari penelitian adalah untuk membuktikan bahwa ekstrak etanol kulit buah manggis (Garcinia mangostana L) yang mengandung senyawa aktif xanthones dengan aktivitas anti-oksidan, anti-bakteria dan anti-inflamasi, dapat menunjang terapi medis untuk jerawat. Uji klinis dilakukan secara acak, berpembanding dan tersamar ganda selama 3 minggu pada 94 subyek berjerawat ringan dan sedang, berumur 18-30 tahun yang tinggal di asrama agar relatif homogen. Parameter penelitian adalah derajat keparahan jerawat menurut kriteria Lehman dan kadar malondialdehid (MDA) di dalam darah subyek. Perlakuan dengan pemberian 400 mg ekstrak 3 kali sehari, bersamaan terapi standar dengan krim topikal asam retinoat 0,025% pada lesi jerawat di wajah pada malam hari. Keparahan jerawat berkurang tidak bermakna (p > 0.2) dan penurunan kadar MDA dalam plasma darah tidak bermakna (p = 0.49).

ABSTRACT
The prevalence of acne (acne vulgaris) is 75-85% in adults, especially in adolescence, and often becomes chronic. Etiopatology of acne is multi-factorial, partly due to the oxidative stress and the influence of hormones and diet. The purpose of this study is to prove that the ethanol extract of mangosteen rind (Garcinia mangostana L) containing xanthones with properties of anti-oxidant, anti-bacterial and anti-inflammatory, can support medical therapy for acne. A randomized, double-blind and controlled clinical trial done for 3 weeks in 94 subjects with mild and moderate acne, aged 18-30 years living in a dorm which is relatively homogeneous. Parameters of the study are the degree of severity of acne according to Lehman criteria and the levels of malondialdehyde (MDA) in the blood of the subjects. Intervention by administering 400 mg extract 3 times a day, along with standard therapy with topical cream of 0.025% retinoic acid applied in acne lesions on the face at night. Improvement of acne severity was not significant (p > 0.2) and decreased levels of MDA in blood plasma was not significant (p = 0.49).

Pewarna tekstil mengandung polutan organik yang dapat menyebabkan pencemaran serius pada air. Proses fotokatalisis dapat mendegradasi polutan organik menjadi senyawa yang tidak berbahaya bagi lingkungan. Titanium dioksida (TiO2) merupakan material semikonduktor yang sering digunakan sebagai fotokatalis tetapi masih menghasilkan aktivitas fotokatalisis yang rendah akibat energi celah pita yang besar. Modifikasi TiO2 untuk meningkatkan sensitivitasnya pada rentang cahaya tampak telah banyak dilakukan, salah satunya dengan komposit logam mulia seperti perak (Ag) untuk memanfaatkan efek localized surface plasmon resonance (LSPR) yang dimilikinya. Pada penelitian ini, sintesis nanokomposit Ag/TiO2 dilakukan dengan metode hijau yang lebih ramah lingkungan, sederhana dan hemat biaya dengan menggunakan ekstrak kulit buah manggis. Kinerja nanokomposit Ag/TiO2 diuji sebagai fotokatalis dalam mendegradasi zat pewarna metilen biru (MB). Hasil uji aktivitas fotokatalisis dengan nanokomposit Ag/TiO2 dengan konsentrasi Ag 45 mM menunjukkan persentase degradasi sebesar 100% di bawah penyinaran cahaya tampak sedangkan TiO2 murni hanya mencapai 20% tingkat degradasi larutan MB. Peningkatan aktivitas fotokatalisis ini dapat dikaitkan dengan peningkatan penyerapan cahaya akibat efek LSPR yang dimiliki Ag. Dengan demikian, komposit TiO2 dengan Ag memiliki potensi besar dalam meremediasi polutan organik dalam limbah zat pewarna. ......Textile dyes contain organic pollutants that can cause serious water pollution. The photocatalytic process can degrade organic pollutants into compounds that are not harmful to the environment. Titanium dioxide (TiO2) is a semiconductor material that is often used as a photocatalyst but still produces low photocatalytic activity due to its large band gap energy. Many modifications of TiO2 to increase its sensitivity in the visible light range have been carried out, one of which is by composite with precious metals such as silver (Ag) to take advantage of its localized surface plasmon resonance (LSPR) effect. In this study, the synthesis of Ag/TiO2 nanocomposites was carried out using a green method that is more environmentally friendly, simple and cost-effective using mangosteen rind extract. The performance of Ag/TiO2 nanocomposite was tested as a photocatalyst in degrading methylene blue (MB) dye. The results of the photocatalytic activity test using Ag/TiO2 nanocomposite with an Ag concentration of 45 mM showed a 100% degradation percentage under visible light irradiation, while pure TiO2 only reached 20% of the MB solution degradation rate. This increase in photocatalytic activity can be attributed to the increase in light absorption due to the LSPR effect of Ag. Thus, the modification of TiO2 with Ag has great potential in remediating organic pollutants in dye effluents.

[Buah Manggis (Garcinia mangostana L.) merupakan buah yang banyak tumbuh di negara tropis, di antaranya Indonesia dan Thailand. Bagian kulit (pericarp) Manggis memiliki banyak khasiat, salah satunya sebagai antikanker. Berdasarkan hal tersebut, dilakukan uji sitotoksisitas untuk melihat efek ekstrak kulit buah Manggis terhadap viabilitas sel leukemia MT-2. Untuk membuat ekstrak, pelarut yang digunakan adalah etanol 99%. Ekstrak etanol kulit buah Manggis dibuat dengan menggunakan alat rotary evaporator. Konsentrasi ekstrak dibagi menjadi delapan yakni, 6,25 μg/ml, 12,5 μg/ml, 25 μg/ml, 50 μg/ml, 100 μg/ml, 200 μg/ml, 400 μg/ml, dan 800 μg/ml. Penambahan DMSO dan media kultur digunakan sebagai kontrol. Ekstrak dan kontrol diberikan kepada sel leukemia MT-2 dan dilakukan uji sitotoksisitas dengan menggunakan metode MTT-Assay. Hasil uji sitotoksisitas berupa kepadatan sel yang dinyatakan dengan Optical Density (OD). Data ini diolah sehingga menghasilkan IC50. Nilai IC50 yang didapatkan adalah 1,72 μg/ml yang tergolong sitotoksik kuat. Data penelitian dianalisis menggunakan uji Kruskal-Wallis, dilanjutkan dengan uji post hoc Mann Whitney dan didapatkan hasil perbedaan bermakna pada kelompok kontrol dan kelompok perlakuan dengan konsentrasi 6,25 μg/ml, 12,5 μg/ml, 25 μg/ml, dan 50 μg/ml.;Mangosteen (Garcinia mangostana L.). is a fruit which grows in tropical countries, includes Indonesia and Thailand. Its peel or pericarp has a lot of benefits. One of the benefits is as anticancer. To test the effectiveness of the peel as anticancer, cytotoxicity test should be done. The previous researches haven?t done the test on leukemia MT-2 cells, so this research did this test on leukemia MT-2 cells to know the effect of mangosteen pericarp ethanol extract to the viability of this cancer cell. This research used ethanol 99% for the solvent. Mangosteen pericarp ethanol extract was made by using rotary evaporator. The extract was adjusted into eight concentrations, which are 6.25 μg/ml, 12.5 μg/ml, 25 μg/ml, 50 μg/ml, 100 μg/ml, 200 μg/ml, 400 μg/ml, and 800 μg/ml. DMSO and culture media were used for the control. Both the extract and the control were given to the leukemia MT-2 cells and were tested for cytotoxicity test. MTT-Assay method was used for the cytotoxicity test. The result of cytotoxicity test is called Optical Density (OD) or the density of the cancer cells which are still ?alive?. This data was processing so that the IC50 can be valued. The IC50 value from this experiment is 1.72 μg/ml which is a very strong cytotoxicity. For data analysis, this research used Kruskal-Wallis Test and was continued by using Post hoc Mann-Whitney Test. From Post hoc Mann-Whitney Test, there are the significant differences between several concentrations. The significant differences can be seen on control group and tested group with concentration 6.25 μg/ml, 12.5 μg/ml, 25 μg/ml, and 50 μg/ml;Mangosteen (Garcinia mangostana L.). is a fruit which grows in tropical countries, includes Indonesia and Thailand.
