Title : Screening for early detection of cardiovascular disease in Systemic lupus erythematosus

Abstract :

Systemic lupus erythematosus (SLE) is a heterogeneous, autoimmune disease, with internal organ injury, which can lead to severe morbidity and mortality. The study included 25 SLE, where their age ranged from 20 to 52 years and the duration of disease ranged from 1 to 30 years. The point of the present investigation was to assess relation cardiovesicular disease and systemic lupus erythromatosus using different biomarker (cholesterol, triglycerides, IL-8, LDH, CK and cTnI), and decide the recurrence of some atherosclerosis biomarkers in SLE patients with and without CVD contrasted to controls group. The results showed that the levels of cholesterol, triglycerides in the SLE patient group were significantly elevated (158.30±4.989 mg/dl and 114.65±14.221mg/dl) compared to healthy control (129.43±5.025mg/dl and 68.91±2.343mg/dl). As well as higher level of IL-8 a significant raised (60.366±9.667) in patient with sle than control group (8.245±0.539) and the IL-8 level was correlated to disease activity. However, no significant difference of IL-8 level with gender, residence, age and duration of disease. Moreover, there was a significant elevated in LDH, CK and cTnI levels (8.839±0.465, 6.661±0.628 and 0.206±0.011) in SLE patients than control group (7.778±0.280, 5.248±0.352 and 0.180±0.008). Conclusions: Abnormal myocardial biomarkers and lipid profiles may be lead to premature atherosclerosis, hence cardiovascular associated with SLE patients and assessment lupus erythematosus as a hazard factor for cardiovascular disease

Title : Secure Files Transfer Mobile Application Using Elliptic Curve Digital Signature Algorithm (ECDSA)

Abstract :

The explosive growth in the use of mobile and wireless devices demands an adequate level of security for such devices. The security level need to be strengthen not only in device, but also in mobile application installed in the devices. This paper presents design in developing secure files transfer mobile application using digital signature technology; Elliptic Curve Digital Signature Algorithm. The developed mobile application consist of 8 main modules, including two modules that apply ECDSA algorithm; sign and send module.  The developed mobile application not only secure the transferred file using digital signature, it also provide signature pad for user to enable user to use electronic signature for document

Title : SUCCESSION PLANNING TRENDS IN GENERAL ORGANIZATION AND HIGHER EDUCATION: A SYSTEMATIC LITERATURE REVIEW

Abstract :

Information and communication technology (ICT) development gives great impact on organization’s growth. Organization growth can cause change of structure in the organization, whether it is predictably happened or in a sudden. Education sector also can have impact on structural change, that’s why succession planning is important. Education Institution needs to prepare the successor in a systematic and continuous program. The way to improve the succession planning process is by implementing Machine Learning. This paper uses Systematic Literature Review to find the trends of implementation machine learning in education sector. The result shows three types of trends such as concept, research and thesis or dissertation product. These three trends also come with some factor to improve succession planning and the implementation of machine learning

Title : Design and Modelling to Improve Battery Charging Efficiency using Photovoltaics

Abstract :

In order to make the charging process of the battery easier, it needs to possess a design tool with suitable characteristics. One of the main characteristics of the battery is the State of Charge (SoC) or simply the battery capacity, which is calculated with the help of the initial voltage value. In this process, a 100Wp photovoltaic panel with 12V DC voltage is applied. The method used is experimental and simulation/modeling, and its purpose is to optimize the efficiency of the process of battery charging. Furthermore, the Arduino microcontroller, which functions are a detector during battery charging, was used to determine the current and voltage sensor controller circuit. The voltage and SoC on the battery are automatically monitored via the LCD and on the SD card using the data logger shield module. ICM algorithm used for modeling-simulation in this study is one of the MPPT type used by photovoltaic systems that work at optimum conditions, thereby producing maximum power. The results showed that the battery charging simulation increased by 0.05% every 30 minutes. Furthermore, the simulation validation using Matlab/Simulink is carried out with data following the prototype design, at an efficiency of 88.37%

Title : Synthesis and Characterization of Impregnated TiO2 Ouw Natural Clay

Abstract :

The research of synthesis of impregnated TiO2 Ouw natural clay with the study of calcination temperature has been done. The calcination process was carried out at temperature variations of 200, 300, and 400 oC. Characterization of the structure was performed by using X-ray diffraction (XRD), scanning electron microscope (SEM) and infrared (IR) spectrophotometer. The result of characterization with XRD showed that the impregnated TiO2 clay at 200 oC has the highest crystallinity. Calcination at 300 oC resulted in the loss of a montmorillonite reflection peak, while calcination at 400 °C resulted in the loss of two montmorillonite reflections and a drastic decrease in intensity. The crystalline phase of TiO2 formed was a combination of the crystalline phases of rutile and anatase, with the rutile crystalline phase being more dominant. The SEM characterization results showed a more even distribution of TiO2 in calcined clay. Calcination at 200 oC resulted in a more even distribution of TiO2 than calcination at 300 oC and 400 oC temperatures
