Abstract

Logam Pb merupakan logam berat pencemar lingkungan yang bersifat racun dan dapat menyebabkan berbagai penyakit diantaranya anemia, keterbelakangan mental, gangguan ginjal, dan beberapa penyakit kardiovaskular. Oleh sebab itu, diperlukan adanya agen penyerap logam Pb dari lingkungan yang tercemar. Salah satu agen alternatif penyerapan logam berat dari lingkungan yang tercemar adalah bakteri. Pada penelitian ini dilakukan eksplorasi bakteri penyerap logam Pb dari air Sungai Ciujung, Serang, Banten. Eksplorasi tersebut dilakukan dengan cara mengisolasi bakteri-bakteri yang mempunyai daya tahan terhadap logam Pb dari sampel air Sungai Ciujung. Isolasi dimulai dengan penapisan bakteri dari sampel air yang dilakukan pada medium padat nutrient agar (NA) yang mengandung 10 ppm logam Pb dengan metode spread plate. Beberapa koloni bakteri yang berhasil tumbuh pada tahap penapisan, diisolasi dan dimurnikan dengan metode streaking pada medium NA padat + 10 ppm Pb berdasarkan morfologinya. Tahap isolasi dan purifikasi tersebut menghasilkan 7 isolat bakteri yang diketahui mempunyai daya tahan terhadap logam Pb dan dinamai sebagai isolat IA2, IA3, IA4, IA3, dan IA4. Lead (Pb) is a kind of heavy-metal pollutant which has toxic characteristic. Acute exposure of lead induces anemia, down syndrome, kidney damage, and some of cardiovascular diseases. Adsorption agent is required to adsorb lead (Pb) from lead-polluted environment. The suggested-alternative agent is bacteria. In this research, the lead (Pb) resistant bacteria have been isolated and purified from the water of Ciujung river, Serang, Banten. The isolation is started with screening the bacteria from the water sample on NA agar plate supplemented with lead (Pb) 10 ppm by spread plate method. The bacteria that could grow in the screening stage are isolated and purified on other NA agar plate supplemented with lead (Pb) 10 ppm by streaking method. This research resulted 7 bacteria named as IA2, IA3, IA4, IA21, IA4 isolate.

Abstract

Saponin merupakan surfaktan nonionik yang terdapat dalam bahan alam dan dapat berfungsi sebagai agen pembersih. Dalam penelitian ini, campuran buah, daun, dan tangkai daun belimbing wuluh diekstraksi untuk mendapatkan ekstrak yang mengandung saponin menggunakan metode ekstraksi maserasi dan berbantukan sonikasi dengan variasi waktu 3, 5, dan 7 hari untuk ekstraksi maserasi serta 10, 20, dan 30 menit untuk ekstraksi berbantukan sonikasi. Variasi rasio simplisia:solven yang digunakan adalah 1:6, 1:7, dan 1:8 (g/mL). Variasi ini dilakukan untuk mendapatkan kondisi ekstraksi yang feasibel. Komposisi dari ekstrak yang dihasilkan dikarakterisasi menggunakan uji LC-MS sedangkan kadar saponin dalam ekstrak dianalisis menggunakan metode gravimetri. Ekstrak kemudian diuji detergensinya melalui uji pengangkatan kotoran untuk mengetahui potensinya pada aplikasi detergen. Hasil menunjukkan bahwa metode ekstraksi berbantukan sonikasi memiliki hasil yang sebanding dengan ekstraksi maserasi namun dengan waktu ekstraksi yang relatif lebih singkat sehingga lebih feasibel digunakan untuk produksi detergen.

Abstract

Indonesia has a vast territory. Approximately 2/3 of Indonesia is water. Indonesia has almost 6% of the world's water resources or approximately 21% of water resources in the Asia Pacific region. Indonesian waters comprise 97.4% seas and 2.6% are rivers, lakes and straits. There are 309 rivers in Indonesia and 49 of them flow through Bandung; one of them is Cikapundung River. Pb(II) ions contained in Cikapundung River has exceeded the quality standard of water river. Therefore, it is necessary to reduce the amount of Pb(II) ions from the river. One of the solutions is by using biodegradable adsorbent, the glutaraldehyde-modified chitosan. Chitosan was obtained from deacetylation of chitin in basic condition. The chitosan was characterized using FTIR showed 85.5% degrees of deacetylation. The other characterization is determination of average molecular mass using Ostwald viscometry method, obtained the average molecular mass of chitosan is 2.7 x 106 g/mol. Furthermore, chitosan was modified by reacting with glutaraldehyde using MAOS (Microwave Assisted Organic Synthesis) method at 80℃ with irradiation power of 100 W for 60 minutes to form glutaraldehyde-modified chitosan with 79% degree of substitution. The synthesized glutaraldehyde-modified chitosan was characterized by FTIR, SEM, SAA and applied as adsorbent of Pb(II) ions. The results showed that the optimum condition of adsorption for 15 mL of Pb(II) solution was achieved at pH 4 using 0.075 grams of adsorbent and 90 minutes of contact time. The adsorption process of Pb(II) ions follows the Langmuir isotherm model and the pseudo-second order kinetics with percent adsorption of Pb(II) ions from the water sample of Cikapundung river is 84% and 50.2%, for sample collected from middle-stream and downstream of river, respectively.

Abstract

Laundry waste containing detergent can release large amounts of Linear Alkylbenzene Sulfonate (LAS), as an active compound, and phosphates into the groundwater. One method for solving this problem is adsorption using natural zeolite. In this study, an innovation was made to utilize zeolite resulting from the processing of laundry wastewater as a growing media with soil for corn plants. The research methodology included activation of Bayah-Banten natural zeolite, adsorption process of LAS and phosphate from laundry waste by varying the contact time (0-60 minutes) and stirring speed (150-350 rpm), analysis of LAS and phosphate content, application of zeolite, obtained from waste treatment, as a soil-zeolite growing media for corn plants, and analysis of corn morphology (stem height, stem circumference and number of leaves).The results showed that the treatment of laundry waste using the adsorption method can reduce the concentration of LAS and phosphate in wastewater. The lowest LAS concentration was obtained at a stirring speed of 300 rpm and a contact time of 60 minutes, from 0.206312 mg/L (initial LAS) to 0.13747 mg/L (final LAS). The lowest phosphate concentration was obtained at a stirring speed of 350 rpm and contact time of 60 minutes, from 0.272184 mg/L (initial phosphate) to 0.06658 mg/L (final phosphate). The application of zeolite as a growing media with a ratio of soil and zeolite of 75:25 showed a good result in the morphology of corn plants, growth in stem height of 67.74% and stem circumference of 41.67%.

Abstract

Bay leaves (Syzygium polyanthum) contain active compounds such as tannins, saponins, flavonoids, and steroids, which offer various benefits in skincare, including antioxidant, antimicrobial, anti-inflammatory, and natural cleansing properties. This study aimed to evaluate the antioxidant activity of bay leaf extract and assess the quality of lotion formulation containing the extract. Extraction was carried out using the maceration method with 70% ethanol as the solvent, and antioxidant activity was tested using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, yielding an IC50 value of 48.64 ppm, indicating moderate antioxidant activity. The lotion formulations were evaluated for organoleptic properties, homogeneity, pH, spreadability, viscosity, and emulsion stability. Results showed that formula F2 had superior quality compared to F1, with a spreadability of 6.5 cm (compliant with SNI 16-3499-1996), pH 6.70 (safe range 4.5–8), creamier texture, lower stickiness and greasiness, and faster absorption time (30 seconds). Formula F2 also demonstrated ideal viscosity (6805 mPaS) and shear thinning properties (torQ 68.1%), which ease application on the skin. Based on these findings, formula F2 meets the requirements for topical cosmetics according to SNI and the Indonesian Pharmacopoeia VI edition, especially in terms of pH, physical stability, and viscosity, and thus shows promising potential for development as a natural-based cosmetic product that is both safe and effective in protecting the skin from free radicals and irritation.
