Abstract

Copper ion as one of the pollutants in industrial wastewater can be treated by the adsorption method. One type of adsorbent can be prepared from rice husk. Rice husk as agricultural waste contains carbon and silica which can act as metal adsorbents. The purpose of this study was to synthesize and characterize silica/carbon composites, as well as test their adsorption as adsorbent on copper (II) ion adsorption by determining the optimum composition of silica/carbon, adsorption capacity, and model of isotherm adsorption. The research method consisted of gasification of rice husks, extraction of silica from rice husk charcoal with potassium carbonate as solvent, manufacture of silica/carbon composites, and adsorption tests. The results showed that the mass ratio of silica to carbon of 2:1 was the optimum composition in the synthesis of silica/carbon composites as adsorbent for the adsorption of copper (II) ion. The silica/carbon composite adsorbent in this composition had the highest adsorption capacity for copper (II) ion and surface area is 75.88 mg/g and 233.45 m2/g, respectively. The optimum adsorption time was obtained for 40 minutes and the model of adsorption isotherm in the form of Freundlich adsorption with R2 = 0.9582.   Abstrak Ion tembaga sebagai salah satu polutan dalam air limbah industri dapat ditangani dengan metode adsorpsi.

Abstract

Hydroxyapatite (HA) has garnered significant attention as a versatile biomaterial with promising applications in drug delivery systems. This study aimed to synthesize and characterize HA derived from eggshells using the hydrothermal method and explore its potential insights for drug delivery systems. We delivered a step-by-step process to produce HA using a hydrothermal method, supported by several analyses, X-Ray Diffraction (XRD) to analyze the crystallinity structure, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), and Brunauer-Emmett-Teller (BET). The stage is continued with a study on the potential of HA as a drug delivery system with UV-Visible spectrophotometer instrumentation. The results suggest that the characterized HA suits drug delivery systems due to its favorable properties. This study contributes to the understanding of utilizing hydroxyapatite from eggshells as a viable material for drug delivery systems, opening avenues for further research and development in this field.

Abstract

The popular use of ciprofloxacin is often irrational, so it causes environmental pollution such as resistance. The solution to overcome environmental pollution due to ciprofloxacin is degradation by using TiO2 nanoparticles. TiO2 nanoparticles performance is influenced by environment such as light source, pH solvent, duration of lighting and TiO2 nanoparticles mass. The residual levels determination of ciprofloxacin was carried out by using a UV-Vis spectrophotometer. Toxicity test of ciprofloxacin degradation products with TiO2 nanoparticles used Escherichia coli bacteria. Liquid Chromatography Mass Spectrometry (LCMS) was used to determine the type of ciprofloxacin degradation product with TiO2 nanoparticles. The optimum condition for the ciprofloxacin degradation with TiO2 nanoparticles is lighting for 5 hours by using a white mercury UV lamp and 50 mg TiO2 nanoparticles with pH solvent of 5.5. The toxicity of ciprofloxacin degradation product with TiO2 nanoparticles was low. The smallest degradation product identified with m/z was p-fluoraniline (m/z 111).

Abstract

Sistem perpipaan dengan bahan dasar dari besi, salah satunya di industri pengolahan minyak bumi, relatif rentan terhadap permasalah korosi. Korosi pada logam dapat terjadi dengan laju bervariasi tergantung pada berbagai faktor, seperti komposisi kimia medium, suhu, dan waktu kontak antara logam dengan medium. Laju korosi dapat hambat dengan teknik penambahan inhibitor ke dalam medium. Inhibitor korosi dari senyawa organik lebih banyak dipilih daripada anorganik. Salah satu inhibitor korosi yang potensial adalah sikloheksilamina. Kemampuan sikloheksilamina sebagai inhibor korosi dipengaruhi oleh konsentrasinya dalam medium, suhu medium, lama pemakaian, dan kondisi dinamik medium. Penelitian ini bertujuan menentukan efisiensi inhibisi korosi oleh inhibitor sikloheksilamina pada pipa baja API 5L Grade B di dalam medium limbah cair minyak bumi. Efisiensi inhibisi korosi tersebut dipelajari pada variasi suhu medium 30, 45, 60, 75, dan 90°C, sedangkan waktu kontak divariasikan selama 1, 2, 3, dan 4 hari. Pengujian inhibisi korosi dilakukan dengan penambahan inhibitor korosi sikloheksiamina sebanyak 0,25% (v/v). Morfologi permukaan, komposisi unsur, dan komposisi senyawa dari sampel pipa baja sebelum dan setelah pengujian inhibisi korosi dikarakterisasi dengan SEM-EDS dan XRD. Hasil penelitian menunjukkan bahwa semakin tinggi suhu medium dan semakin lama waktu kontak, efisiensi inhibitor korosi sikloheksilamina cenderung mengalami penurunan. Efisiensi inhibisi korosi tertinggi oleh sikloheksilamina pada posisi BLC (bottom line corrosion) dicapai sebesar 60,1% ketika pengujian dilakukan pada suhu medium 60°C selama 1 hari. Sedangkan pengujian korosi pada posisi TLC (top line corrosion) memberikan efisiensi inhibisi korosi tertinggi sebesar 91,9% ketika dilakukan pada suhu medium 45°C dan lama kontak 1 hari.

Abstract

Based on variations in calcination temperature, gamma alumina has successfully been made using a simple sol-gel method for Pomalaa magnesium-laterite adsorption from the South East of Sulawesi. The laterite leached by sulfuric acid was then precipitated by ammonia, to make the magnesium was separated from its main impurities (Si, Fe and Al). Temperature variations at 500, 650, 800 and 950 °C in gamma alumina making formed the gamma alumina phase while the alpha alumina phase was formed at 1100 °C. The higher calcination temperature the lower the specific surface area respectively from 196.385, 156.239, 105.725, 96.134 and 15.396 (m2/g). This results in decreasing the magnesium of the laterite 9.04, 8.70, 8.09, 6.39 and 0.29 (mg/L) respectively. The 800 °C-calcination gamma alumina has the highest volume of the pore, namely 0.3265 mL/g and the radius of 61.76 Å. The gamma alumina isotherm curve is type IV. The SEM-EDS test shows an aggregation spherical shape. Gamma alumina was detected to adsorb Mg laterite. The X-ray mapping of SEM-EDS test shows even distribution between gamma alumina, magnesium and nickel. The highest adsorption is retained by GA-800/3 sample, namely 81.31 %.

Abstract

In the development of advanced materials and various technological applications, the preparation and sintering processes have become two important factors in determining material characteristics. This research focuses on two main aspects, namely the effect of fish bone preparation by soaking in acetone and the surface area of the material in the sintering process as part of the process of developing better materials. This research aims to determine the effect of soaking fish bone powder with acetone and the effect of the surface area of sintered fish bones to produce hydroxyapatite (HA). The immersion process with acetone is included in the sample preparation stage, while the sintering process is included in the material synthesis stage. These two things can affect the characteristics of the HA produced after analysis from the X-ray diffraction test. The HA structure obtained from all samples is hexagonal with cell parameter values a = b ≠ c and space group P 63 / m, where all samples have a value range of a = b = 9,42 Å and c = 6,88 Å. HA crystallinity was identified through the XRD peak at 2θ = 25,8 (002); 31,7 (211); 32,1 (112); 32,8 (300); 34,0 (202); 39,7 (310); 46,6 (222); 49,4 (213); 50,4 (321). The PAF-900 and CAF-900 samples are similar to HA in JCPDS 01-089-4405 whose compound formula is Ca5(PO4)3(OH) while the PWAF-900 sample is similar to HA in JCPDS 01-075-3727 whose compound formula is Ca5(PO4)3(CO3)0.01(OH)1.3. The percentage of crystallinity of PAF-900, CAF-900, and PWAF-900 respectively was 84,767; 73,506; and 71,962% with HA grain sizes of 0,8964; 0,6808, and 0,7398 nm. The HA density of PAF-900 and CAF-900 samples is 3,149 g/cm3 while PWAF-900 is 3,146 g/cm3. Based on this description, it can be concluded that the soaking preparation stage with acetone produces HA with the chemical formula Ca5(PO4)3OH with a higher percentage of crystallization and is denser compared to HA obtained without going through the soaking preparation stage with acetone. The sintering stage also plays an important role in increasing the crystallization percentage. The surface area of the material being sintered also influences the percentage of crystallization and the grain size of the resulting HA. Sintered fish bone powder produces a greater percentage of crystallization and grain size than fish bone chunks

Abstract

Hydroxyapatite (HA) was successfully synthesized using the hydrothermal method. This study aimed to analyze the effect of a low solid/liquid ratio on the properties of HA crystals. HA synthesis was performed using chicken eggshells and the hydrothermal method at a temperature of 150°C. The solvent amount was kept constant, while the solid amount varied (half-reaction). The characteristics of HA were determined using XRD, FTIR, PSA, and SEM. The results showed that the purity and size of HA were influenced by a low solid/liquid ratio, while the crystallinity remained relatively unchanged, directly impacting the lattice parameter value. FTIR analysis revealed the absence of the O-H group in the sample with the low solid/liquid ratio. PSA results showed a smaller particle size of 0.995 µm for the sample with the low solid/liquid ratio. SEM results demonstrated a smaller particle size in the sample with a low solid/liquid ratio when observed at the same magnification

Abstract

Tingginya jumlah penderita virus Covid-19 di Indonesia, menandakan potensi penularan yang relatif mudah. Kurangnya pemahaman protokol kesehatan di masa pandemi dan rendahnya target vaksinasi diduga menjadi penyebab tingginya penyebaran virus Covid-19 di hampir seluruh kecamatan di Kabupaten Bandung, termasuk Kecamatan Banjaran, khususnya di Desa Banjaran. Hingga akhir tahun 2021 Pemerintah Jabar menargetkan capaian vaksinasi sebesar 70%, namun masih tercatat sebesar 60% untuk Desa Banjaran. Lansia adalah kelompok usia yang belum divaksinasi karena alasan penyakit sistemik, kehalalan vaksin dan efek samping pasca vaksinasi. Program KKN Tematik Kesehatan Masyarakat (PPM) yang diselenggarakan oleh UNPAD-UNICEF yang berlangsung pada tanggal 25 November-25 Desember 2021 melakukan edukasi penerapan protokol kesehatan 3M di SMPN 1 Banjaran dan percepatan sasaran vaksinasi di Desa Banjaran yang bertujuan untuk membantu perangkat desa dan petugas kesehatan Desa Banjaran untuk menekan penyebaran virus Covid-19. Kegiatan PPM dilaksanakan dengan metode hybrid, dengan tiga tahapan kegiatan yang terdiri dari tahap persiapan, tahap pelaksanaan, dan tahap tindak lanjut. Berdasarkan hasil pos test, 77% dari 77 siswa memahami materi protokol kesehatan yang diberikan. Sementara percepatan kegiatan target vaksin tercatat meningkat menjadi sebanyak 36 orang di RW 06 dan sebanyak 67 orang di RW 07.
