Abstract

Telah dilakukan sintesa lapisan tipis MgTiO3 dengan menggunakan metode Sol Gel. Lapisan tipis MgTiO3 dibuat dengan mencampurkan TiO dan MgSO4 sebagai prekursor. Larutan ini kemudian diaduk selama 1 jam agar campuran menjadi homogen dengan menggunakan magnetic stirrer. Lapisan tipis MgTiO3 dipanaskan dengan variasi suhu mulai dari 300, 400, 500 dan 60oC selama 1 jam. Berdasarkan hasil pengujian XRD menunjukkan bahwa pada suhu 300 - 500oC nilai ukuran butir kristal semakin besar, sementara pada suhu 600oC ukuran butir kristal mengecil. Struktur kristal yang terbentuk dari lapisan tipis MgTiO3 adalah rutil. Hasil SEM menunjukkan lapisan MgTiO3 terdeposisi dengan baik yang ditunjukkan dengan tidak munculnya retakan pada permukaan lapisan serta terdapat adanya pori yang terbentuk dan ketebalan lapisan tipis MgTiO3 berkisar antara 1,67 – 1,79 µm. Hasil pengujian UV-Vis menunjukkan suhu pemanasan mempengaruhi turunnya nilai band gap. Semakin tinggi suhu pemanasan semakin kecil band gap yang dihasilkan, yaitu pada suhu 300oC bernilai 3,22 eV dan pada suhu 600oC bernilai 3,02 eV.MgTiO3 thin films synthesis has been done using Sol Gel method. The MgTiO3 thin films is made by mixing TiO and MgSO4 as precursors. This solution is then stirred for 1 h to have homogeneous mixture by using a magnetic stirrer. The MgTiO3 thin films is heated with temperature variations range of 300, 400, 500 and 600°C for 1 h. Based on XRD test showed that at 300 - 500 oC value of crystalline grain size was increased, while at 600oC the size of crystal grains decreased. The crystalline structure formed from a thin films of MgTiO3 is rutile. The SEM results show a well-deposited MgTiO3 films which is indicated by the absence of cracks on the surface of the coating and there is a pore formed and the thickness of the MgTiO3 thin films range of 1.67 to 1.79 μm. UV-Vis test show that the heating temperature affects the decrease in band gap value. The higher the heating temperature give the smallerof band gap, ie at a temperature of 300oC worth 3.22 eV and at a temperature of 600oC worth 3.02 eV, respectively.Keywords: MgTiO3 thin films, Sol Gel, XRD, SEM, UV-Vis.DAFTAR PUSTAKAAngela, R., dan Pratapa, S. 2012.

Abstract

Study on hydrogen gas concentration to changes in voltage and resistance using semiconductor hydrogen gas sensor has been done. The system which has been designed will measure any changes in the voltage and resistance of the sensor automatically when the sensor is given a variation of concentration on hydrogen gas. On the condition of gas with low concentration, the sensor output voltage obtained worth 0:08 Volt and the sensor resistance value of 180 KΩ. On the increase in gas concentration causes an increase in sensor output voltage and a decrease in the value of resistanceStudi tentang pengaruh konsentrasi kadar gas hidrogen terhadap perubahan tegangan dan resistansi menggunakan sensor gas hidrogen berbasis semikonduktor telah berhasil dilakukan. Sistem yang telah dirancang akan mengukur setiap perubahan tegangan dan resistansi secara digital pada sensor saat diberikan variasi terhadap konsentrasi kadar gas hidrogen. Pada kondisi gas dengan konsentrasi rendah diperoleh tegangan output sensor senilai 0.08 Volt dan nilai resistansi sensor sebesar 180 KΩ. Pada peningkatan konsentrasi gas menyebabkan peningkatan tegangan output sensor dan sebaliknya terjadi penurunan pada nilai resistansi

Abstract

Study of deposit Cesium-137 (137Cs) activity as a result of the fission product of Fukushima Daiichi Nuclear Power Plant after earthquake and tsunami in 2011 has been done. The purpose of the present research is to study the deposit 137Cs activity on the land and the Sea of Japan and then to estimate a model of 137Cs distribution on the earth's surface of Japan. The stability of nuclei decay equation is used to obtain a deposit 137Cs activity depending on time, theoretically. The Pasquill-Gifford equation is used to estimate a distribution of 137Cs activity on the earth surface from the original source. The results suggested that Hatachinaka city, the largest measurement point, for about 60 years forward, 137Cs activity levels reach about 54 Bq. In the Sea of Japan at the point of sensor C47, which it has the largest value, the accumulation of deposit 137Cs activity gives about 0.69 Bq at the time of the next 60 years. For the distribution of 137Cs activity, the concentration values at a distance of 200 m from the original source obtained maximum for all case.

Abstract

Pengukuran intensitas radiasi pada beberapa filter rokok komersial menggunakan detektor Geiger-Muller dengan sumber radiasi Sr-90 dan Am-241 telah dilakukan. Pengukuran ini dilakukan untuk menghitung besarnya koefisien atenuasi dari filter rokok tersebut. Dalam penelitian ini, jarak dari filter rokok dengan sumber radiasi divariasikan yakni sebesar 6 cm, 7 cm dan 8 cm. Terdapat dua jenis perlakuan sampel yakni sampel filter yang mendapatkan gaya tekan sebesar 5 ton selama 10 menit dan non-tekan (kondisi normal). Hasil penelitian menunjukkan bahwa semakin jauh sumber radiasi terhadap detektor, maka semakin kecil intensitas radiasi yang diperoleh. Daya tembus radiasi dengan sumber Sr-90 lebih besar dibandingkan dengan radiasi Am-241. Oleh karena itu, unsur radioaktif Sr-90 memiliki intensitas yang lebih besar dibandingkan dengan unsur radioaktif Am-241. Study on amount of radiation intensity for some commercial cigarette filters using detector Geiger-Muller with radiation source of Sr-90 and Am-241 has been done. The purpose of the measurement is to measure a mass attenuation of the filter. In this research, the distance of the cigarette filters with the source of radiation was varied i.e 6 cm, 7 cm and 8 cm. The sample cigarette filters was treated, i.e press and non-press (normal condition). The cigarette filters are pressed with a force of 5 tons for 10 minutes using hydraulic press. It was founded that the radiation intensity will decrease with the distance. The amount of radiation intensity of Sr-90 is more higher than Am-241.

Abstract

Application of a curved vibrating wire method (CVM) to measure gas viscosity has been widely used. A fine Tungsten wire with 50 mm of diameter is bent into a semi-circular shape and arranged symmetrically in a magnetic field of about 0.2 T. The frequency domain is used for calculating the viscosity as a response for forced oscillation of the wire. Internal friction is one of the parameter in the CVM which is has to be measured beforeahead. Internal friction coefficien for the wire material which is the inverse of the quality factor has to be measured in a vacuum condition. The term involving internal friction actually represents the effective resistance of motion due to all non-viscous damping phenomena including internal friction and magnetic damping. The testing of internal friction measurement shows that at different induced voltage and elevated temperature at a vacuum condition, it gives the value of internal friction for Tungsten is around 1 to 4 10-4.

Abstract

Sebuah perancangan sensor untuk mendeteksi kebocoran gas hidrogen pada saluran pipa tertutup telah berhasil dilakukan. Sensor yang digunakan berbasis bahan semikonduktor berbahan metal oksida. Sistem yang dirancang adalah dengan membandingkan nilai resistansi awal sensor tanpa gas hidrogen (Ro) dengan resistansi pada saat terdapat gas hidrogen (Rs). Nilai perbandingan tersebut akan dikonversi untuk menentukan kadar konsentrasi gas dalam skala ppm menggunakan persamaan yang diperoleh berdasarkan datasheet sensor yang telah diberikan. Pada saat kebocoran gas betekanan rendah, yakni pada konsentrasi (ppm) rendah, diperoleh waktu respon sensor bernilai 300 s sedangkan pada kondisi gas betekanan tinggi, yakni pada konnsentrasi tinggi, diperoleh nilai kurang dari 150 s. Akurasi pengukuran resistansi didapatkan masih berada dalam jangkauan karakteristik sensor. Design of hydrogen gas sensor to detect hydrogen gas leakage in the pipe has been done. The sensor is based on metal oxide semiconductor. The typical working system of the semiconductor sensor is based on comparison of the resistance in the system, i.e. resistance without hydrogen gas (Ro) and with hydrogen gas (Rs). The gas concentration (ppm) is determined by using an equation derived from the datasheet given. The response time for low concentration is 300 sec and less than 150 sec for high concentration. Furthermore, the measurement accuracy of resistance is still on the range of the characteristics refer to the sensor. Keywords: Gas, Hidrogen, waktu Respon, Sensor, semikonduktor
