Judul: Uji Sifat Listrik dan Sifat Optik Fotodetektor Berbasis Film Tipis BST Didadah Ta2O5.
Abstrak: Kajian material ferroelektrik semakin banyak dilakukan dan dikembangkan oleh para ilmuwan. Salah satu material ferroelektrik yang banyak dikembangkan adalah Barium Strontium Titanate (BST). Barium Strontium titanate (BST) thin film banyak diaplikasikan sebagai Non Volatile Memory Device, Dynamic random Acces Memory (DRAM), voltage tunable device, Infra Red (IR), sensor kelembaban, sensor cahaya dan sensor gula. Selain itu, BST thin film dapat diaplikasikan sebagai fotodetektor. Salah satu jenis fotodetektor yang pernah dibuat adalah ZnSe metal–insulator–semikonductor (MIS). Fotodetektor ini disintesis pada substrat ZnSe yang dilapisi oleh BST (Ba0.25Sr0.75TiO3) dan SiO2. Selain itu terdapat pula fotodetektor berbasis GaN. Fotodetektor ini dibuat dari material yang memiliki energi bandgap yang lebar. Hal ini menyebabkan terbentuknya fotodetektor yang sensitif pada daerah panjang gelombang sinar ultra violet. Hal ini menimbulkan munculnya ide pembuatan fotodetektor berbasis film tipis BST yang dibuat pada substrat silikon. Fotodetektor ini sensitif pada daerah panjang gelombang sinar tampak dan infra merah. Sehingga dapat diaplikasikan sebagai sensor warna yang membutuhkan sensor yang peka pada daerah panjang gelombang cahaya tampak

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.

Judul: The Effect Cassava Leaves Meal in The Diets on Body Weigbt, Percentage of Digestive Tract and Viscera of Mule Duck.
Abstrak: The mule ducks are the crossbreed between common duck females (Anas plathyrhynchos) and muscovy ducks (Cairino moschata) to improve the meat production in order to meet the animal protein requirement of the people. One of the problems in husbandry farming is highly feed cost. This problem can be solved with using highly available local sources and cheapness. Cassava leaves (Manihot esculenta Crantz) is the one local sources which can be used as an alternative feed, because it contains a rather high protein (24.1%) aud vitamin A (10,000-13,000 IU). A highly Hydrocyanide (HCN) as well as crude fiber in the cassava leaves are the limiting factors to be used as poultry diet. The ducks have more ability in digest the crude fiber than chicken. So that, using some cassava leaves in the diet does not make any problem.
