An approximate solution of the Dirac equation for a spin-1/2 particle under the influence of q-deformed hyperbolic Pöschl–Teller potential combined with trigonometric Scarf II non-central potential is studied analytically. It is assumed that the scalar potential equals the vector potential in order to obtain analytical solutions. Both radial and angular parts of the Dirac equation are solved using the Nikiforov–Uvarov method. A relativistic energy spectrum and the relation between quantum numbers can be obtained using this method. Several quantum wave functions corresponding to several states are also presented in terms of the Jacobi Polynomials.

Student attendance is essential in the learning process. To record student attendance, several ways can be done; one of them is through student signatures. The process has several shortcomings, such as requiring a long time to make attendance; the attendance paper is lost, the administration must enter attendance data one by one into the computer. To overcome this, the paper proposed a web-based student attendance system that uses face recognition. In the proposed system, Convolutional Neural Network (CNN) is used to detect faces in images, deep metric learning is used to produce facial embedding, and K-NN is used to classify student's faces. Thus, the computer can recognize faces. From the experiments conducted, the system was able to recognize the faces of students who did attend and their attendance data was automatically saved. Thus, the university administration is alleviated in recording attendance data.

Dengue Haemograffic fever is a vector borne disease which caused outbreaks and death. There is no applied vaccine until now, so the effort of prevention and control is to terminate chain of infection mosquito breeding. Factors which influenced  the female mosquitoe to lay their eggsare type of container, color, water, temperature, water source, humidity and environment condition. This study was conducted to determine the preferences of Ae. aegypti mosquitoes to lay aggs in various colors ovitrap in the laboratory of Balai Litbang P2B2 Donggala, January until March 2015. Three repetitions with plastic cup black, blue, white, yellow and pink have been performed with water and filter pappers. 30 mosquitoes blood saturation included in the containers with various colors. The result showed that most of female mosquito laid their eggs in plastic cup black (53,2%). ANOVA analysis showed that the diversity of colors ovitrap produce different the number of eggs Ae. aegypti in each type of countainer color. It is recommended to use black ovitrap for controling populations of Ae, aegypti in environment with regular monitoring.
