Metals, ceramics, and reinforced polymers have all been used as dental post material. “FRC post = Fiber Reinforced Composite Post is very popular at this moment. Many kinds of materials have been explored as fiber reinforcement for this type of post, including carbon. In this study, activated carbon is combined with zirconia (through sol-gel templating) and PMMA, as an alternative material for composite dental post. Activated carbon is extracted from Eucalyptus papuana wood, a natural resource that is very abundant and economical. Purpose, To make an activated carbon-reinforced zirconia composite structure, to study the suitable zirconia-precursor concentration in enhancing the mechanical properties of the post material to besimilar to the commercial composite post. Methods: Eucalyptus- papuana wood was pyrolyzed at 750°C,producing activated-carbon with tubular pores. The synthesized carbon was then combined with zirconia, using sol -gel templating at 4 different zirconia-precursor molarities. After calcination at 900°C, the activated carbon-zirconia structure was impregnated with PMMA. Morphological image of the transverse surface zirconia showedattachment on the tubular wall of activatedcarbon and the tubular pores and were evenly covered with PMMA. The 3-point bending test showed that all the zirconia- precursor concentrations failed to produce flexural strength in the range of commercial posts (450-1100 MPa), but all their elastic moduli are equal with commercial posts (8-50 GPa). The values of modulus of elasticity of this materialwere comparable to the commercial composite posts with the highest value of 24.247 GPa produced from 0.8 M precursor. The higher the precursor concentration, the higher the mechanical properties of the material. Conclusion:the composite PMMA reinforced with activated carbon-zirconia structure was established, the concentrations of the precursor 0.05, 0.1, 0.4, and 0.8 are correspondsto the modulus of elasticity ofcommercial composite post, but none of these concentrations could produce flexural strength equivalent to the commercial posts

Battery consists of cathode, anode, and electrolyte. Spinel Lithium Titanate, known as Li4Ti5O12spinel is an alternative material for anode substituting carbon due to its ability to generate large current for high-discharged battery. It can be applied for the electric car battery.A commonly used battery synthesis method is High Energy Ball Milling. However, that method is time consuming and require massive amount of energy. In this research, Li4Ti5O12synthesized as an anode for lithium ion battery through sol-gel method with chitosan variable as the dispersing agent. Formed gel then calcinated with temperature of 750oC. Synthesized powder was characterized using XRD (X-ray Diffractometry) and SEM (Scanning Electron Microscopy) methods.Li4Ti5O12 was successfully synthesized with sol-gel method and chitosan as the dispersing agent. Based on the XRD characterization result, at the 750oC calcination temperature, 95–97%. Li4Ti5O12 phase was formed. Chitosan played a good role of being the dispersing agent because it was able to increase crystallinity, reduce the size of Li4Ti5O12powder particle, and reduce the particle agglomeration. Observation with SEM shows that the particle size is categorized as submicron, which size is ranged in 75–300 nm. It is potential to be used as the material for lithium battery anode that come near to theoretical capacity. Baterai terdiri dari katoda, anoda, dan elektrolit. Lithium titanat spinel atau Li4Ti5O12 spinel adalah material anoda alternatif untuk menggantikan karbon karena memiliki kemampuan untuk memberikan arus besar yang dapat diaplikasikan sebagai baterai pada mobil listrik.Metode yang saat ini sering digunakan untuk pembuatan baterai adalah High Energy Ball Milling, namun energi yang dibutuhkan sangat besar dan waktu pengerjaan dengan metode ini pun cukup lama. Dalam penelitian ini dilakukan sintesis serbuk Li4Ti5O12 sebagai anoda baterai lithium ion dengan metode sol-gel dengan variabel kitosan sebagai dispersing agent. Gel yang terbentuk dikalsinasi pada variasi suhu 750oC. Serbuk hasil sintesis dikarakterisasi menggunakan metode XRD (X-ray Diffractometry) dan SEM (Scanning Electron Microscopy). Pada penelitian ini telah berhasil disintesis Li4Ti5O12 dengan metode sol-gel dengan kitosan sebagai dispersing agent. Pada suhu kalsinasi 750oC terbentuk 95–97% fasa Li4Ti5O12 yang diketahui dari berdasarkan hasil karakterisasi XRD, kitosan berperan baik sebagai dispersing agent karena dapat meningkatkan kristalinitas, memperkecil ukuran partikel dari serbuk Li4Ti5O12, dan mengurangi aglomerasi partikel. Hasil pengamatan dengan SEM menunjukkan bahwa ukuran dari partikel tergolong pada ukuran submikron yaitu berkisar 75–300 nm yang berpotensi sebagai material anoda baterai lithium yang mendekati kapasitas secara teori.

The rising complexity and needs of healthcare nowadays is demanding the science and engineering to bring out the new concept of health treatment that enabled more effective drug administration. Silica, known as one of the most potential resources in Indonesia even in the whole world, can cope with poor temperature and chemical stability limitations. Silica has a good compatibility and stability which can lead it to be a promising material to encapsulate bioactive or drug and effectively deliver them to human body. The used of sodium silicate as precursorwass intended to encapsulate the active substance, in this case was chlorhexidine 2%. The encapsulation was done by Stober process. By Stober process it is possible to produce spherical and monodispersed nanoparticles with controlable particle size and drug release rate in ambient temperature. This study was purposed to generate approximately 1 µm sized microcapsules of silica containing chlorhexidine digluconate 2% encapsulated with alginate and chitosan. Microcapsules were intended to be used in medicament root canal treatment. The Stober process was modified with aging time and consentration of chitosan solution to control the size of microcapsules. Varied aging times are 72 hours, 36 hours, 24 hours, 8 hours, and 4 hours. The most suitable modified result, which was 4 hours aging time with 100-500 nm particle size then soaked in chlorhexidine 2% and combined with alginate and chitosan in ratio 6% :2% to form clustered encapsulated microcapsule under 1 µm in size. The characteristics of microcapsules were observed by scanning electron microscopy, FTIR spectroscopy. The release rate of encapsulated active substance observed was forty minutes longer than the non-encapsulated, by UV-Visible spectroscopy. Perkembangan kehidupan manusia telah menuntut ilmu pengetahuan dan teknologi untuk menemukan cara terbaru bagi perawatan kesehatan dan teknik penyaluran obat. Silika sebagai sumber daya mineral terbesar di Indonesia bahkan di dunia berpotensi sebagai material yg dapat menyalurkan zat aktif ke dalam tubuh tanpa batasan efektivitas karena pengaruh suhu ataupun kestabilan kimia bahan itu sendiri. Pada penelitian ini dilakukan enkapsulasi zat aktif chlorhexidine 2% melalui proses Stober agar partikel yang dihasilkan berbentuk spherical dengan ukuran yang dapat dikontrol dan terdispersi secara merata. Sodium silikat digunakan sebagai precursor. Mikrokapsul yang dihasilkan ditujukan untuk perawatan saluran akar gigi. Proses Stober dilakukan dengan variansi waktu aging dan konsentrasi kitosan sebagai dispersan untuk mengontrol ukuran partikel. Waktu aging bervariasi mulai 72 jam, 36 jam, 24 jam, 8 jam, dan 4 jam. Dari variasi waktu aging, mikrokapsul terbaik akan dilakukan impregnasi chlorhexidine 2% dan dienkapsulasi dengan 6% kitosan 2% dan 2% alginat 0,5% sehingga didapatkan mikrokapsul dengan ukuran kurang dari 1 µm. Pada hasil sintesis kemudian dilakukan karakterisasi SEM, dan FTIR. Melalui UV-Vis diketahui waktu aktifdari zat aktif bertambah 40 menit dengan enkapsulasi.
