Ceramics of PbZrxTi1-xO3 (PZT) and 0.5 %, 1 %, 1.5 % tantalum oxide doped PbZr0.525Ti0.475O3 (PTZT) were successfully deposited by solid state reaction. The PZT and PTZT ceramics were analyzed by an x-ray diffraction (XRD). The XRD spectra were recorded by Diano type 2100E diffractometer using a CuKα (λcu = 1.54056 Å) radiation at 30 KV and 30 mA (900 watt). The spectra showed that PZT and PTZT ceramic are polycrystalline with tetragonal structure. The lattice constants analysis of the grown ceramics were described by Delphi program. Using Cohen’s and Cramer’s algorithms in the Delphi program, the lattice constants are a = b = 4.094 Å, c = 4.142 Å, c/a ratio = 1.012 for PZT ceramic, and a = b = 4.075 Å, c = 4.088 Å, c/a ratio = 1.003 for PTZT ceramic. The lattice constants are a = b = 4.094 Å, c = 4.142 Å, c/a ratio = 1.012 for PZT ceramic, a = b = 4.122 Å, c = 4.134 Å, c/a ratio = 1.003 for PTZT 0.5 % ceramic, a = b = 4.075 Å, c = 4.088 Å, c/a ratio = 1.003 for PTZT 1 % ceramic, a = b = 4.248 Å, c = 4.179 Å, c/a ratio = 0.984 for PTZT 1.5 % ceramic. Increasing tantalum oxide doping in PZT from 0 % to 1.5 % lead to the decrease in c/a ratio. The smaller value of the c/a ratio of PTZT ceramic than those of PZT ceramic is possibly associated with the anti site defects of Ta dopants.

Ba0.5Sr0.5TiO3 (BST) and gallium doped BST (BGST) thin films were successfully deposited on p-type Si(100) substrates. The thin films were fabricated by the chemical solution deposition (CSD) and spin coating method, with 1.00 M precursor and spinning speed of 3000 rpm for 30 seconds. The post deposition annealing of the 9 films were carried out BST without gallium (BGST 0%) annealing 850OC, BGST 0% annealing 900OC, BGST 0% annealing 950oC, BGST 5% annealing 850oC, BGST 5% annealing 900oC, BGST 5% annealing 950oC, BGST 10% annealing 850oC, BGST 10% annealing 900oC, BGST 10% annealing 950oC for 15 hour in oxygen gas atmosphere, respectively. The resistance and electrical conductivity of the grown thin films are characterized by I-V converter, meanwhile surface roughness of the grown thin films are characterized by atomic force microscopy (AFM) method. The electrical conductivity of the grown thin films BGST due to semiconductor. The results show that resistance and electrical conductivity of the thin film have strong correlation to the annealing temperature, concentration dopant and surface roughness.

ABSTRAKAspek lingkungan hidup kemungkinan terganggu akibat kegiatan eksploitasi sumber daya alam. Mineral dan batuan sebagai salah satu sumber daya alam pada umumnya tersebar di daerah terpencil yang masih memerlukan pengembangan. Pada sisi ini, kehadiran perusahaan pertambangan sangat penting peranannya bagi kemajuan dan pembangunan serta meretas keterisolasian suatu daerah. Wilayah sekitar Gunung Sudamanik, Kecamatan Cigudeg, Kabupaten Bogor tumbuh dan berkembang karena pertambangan andesit. Gunung Sudamanik telah dan masih dieksploitasi lima perusahaan tambang andesit yang memiliki Izin Usaha Pertambangan (IUP) dengan luas total Wilayah Izin Usaha Pertambangan (WIUP) seluas 113 hektar. Pada tahun 2012, total produksi batuan kelima perusahaan adalah 3.984.785 ton atau rata-rata 332.065,4 ton per bulan. Produksi batuan tersebut dihasilkan dari peledakan yang dapat mencapai lima kali peledakan atau lebih setiap hari. Getaran dan bunyi ledakan yang disebabkan peledakan ini kemungkinan berdampak terhadap lingkungan hidup, terutama pada konstruksi rumah dan kenyamanan masyarakat yang bermukim di sekitar kaki Gunung Sudamanik. Pemukiman penduduk yang paling dekat lokasi peledakan andesit berada pada tiga kampung/dusun yaitu Kampung Kadaung, Lebakwangi Lapangan dan Lebakwangi Girang. Ketiga kampung tersebut secara administratif berada dalam Desa Rengasjajar. Rumah warga pada pemukiman yang paling dekat ke lokasi peledakan batuan andesit berjarak sekitar 337 – 616 meter. Hasil penelitian menunjukkan bahwa pemakaian 90,5 kg bahan peledak delay yang sama pada jarak 148 m mengakibatkan tingkat getaran tanah maksimum 7,71 mm/s yang telah melewati baku mutu kelas 3 SNI 7571 : 2010. Dan pemakaian bahan peledak mulai dari 77,4 kg sampai 1310,4 kg setiap peledakan tidak menimbulkan dampak kebisingan pada pemukiman warga.ABSTRACTLiving environment aspects are possibility disrupted by the exploitation of natural resources. Minerals and rocks as one of the natural resources in general are scattered in remote areas that still need development.

Rice husk has high silica (SiO2) content and can be used as the primary material for making nano-silica. One of the methods for synthesizing nano-silica was the hydrothermal method. The objective of this study was to synthesize nano-silica from rice husks by observing the effect of temperature in the hydrothermal process on the structure, electrical and particle properties of nano-silica. The hydrothermal process temperature was 150, 200, and 250 °C for 4 hours. The results showed that all nano-silicas were in the amorphous phase. The particle size was in the range of 0.16-13.49 nm with more uniform size distribution on nano-silicas of 200 °C and 250 °C than nano-silica at 150 °C. These three nano-silicas were included in the semiconductor category by increasing temperature and frequency. In addition, these treatment variations resulted 200 °C for 4 hours and pressure of 2 atm as the optimum treatment for manufacturing nano-silica of rice husk ash. This nano-silica could be used as semiconductor material for electronic industry.

Silica is the most mineral found on earth and is widely used in industry. Silica used in industry is usually silicon dioxide with a purity ≥ 95% and its often sold at a higher cost. To obtain the silica at a lower cost, silica extraction from biomass such as rice husk can be conducted. The purity of silica extracted from biomass tends to be lower than that of mineral silica. Silica with low purity can be increased by adjusting the temperature and the rate of temperature rise. This research aims to obtain the best design to determine the purity of silicon dioxide. The design of this study was generated based on the A-optimality criterion using the DETMAX algorithm. The A-optimality criterion is minimizing the trace of the variance-covariance of the parameter estimation. The best design points obtained using A-optimal design consist of three temperature groups: the minimum temperature of 800°C, the middle temperature of 850°C, and the maximum temperature of 900°C, with varying rates of temperature rise. Points were repeated at the temperature of 850°C, with rates of temperature rise of 1.67°C/min and 3.34°C/min.

One of the obstacles that arise in optimal design is the non-linear model. The relationship between temperature factors and the temperature increase rates with the purity of silicon dioxide (SiO2) forms a non-linear pattern. Determining the optimal design for a non-linear model is relatively more complex than a linear model because it requires additional information in its information matrix. Therefore, this issue necessitates further research on optimal design in non-linear models. This study uses the polynomial Taylor approach to approximate the non-linear equation through a linear equation using the appropriate optimal design methods, namely A-Optimal and I-Optimal criterion. The point search algorithm used was variable neighborhood search, this algorithm searches for design points by exploring several different neighborhood structures. These two methods were chosen to compare the characteristics and performance of the designs produced, aiming to obtain an optimal design to improve SiO2 purity (non-linear case) using the same algorithm, VNS. The research results showed that the design pattern produced by the A-Optimal design formed three temperature groups, namely the minimum temperature of 800°C - 820°C, the middle temperature of 850°C, 860°C, and the maximum temperature of 900°C, with varying temperature increase rates in the design area. The design pattern produced by the I-Optimal design formed a full quadratic pattern, namely the minimum temperature of 800°C and the maximum temperature of 900°C, with varying temperature increase rates in the design area. The I-Optimal design demonstrated the best performance (most optimal) in the aspect of prediction variance compared to the A-Optimal design across all alternative points in this study to improve SiO2 purity.
