Analisis Potensi Likuefaksi Berdasarkan Metode Global Geospatial Model di Kecamatan Sanden Kabupaten Bantul Yogyakarta
No full textThis research is motivated by the liquefaction phenomenon that has occurred in Yogyakarta area due to the 2006 earthquake. This study aims to find out the probability of liquefaction based on the Global Geospatial Model (GGM) method and create a map of the distribution of liquefaction-prone settlements. This research was conducted in Sanden Subdistrict in the southern part of Bantul Regency. The GGM method utilizes three main parameters: shear wave speed at a depth of 30 meters (Vs30), acceleration of ground vibration (PGA) and ground wetness index (CTI). Vs30 is derived from the inverse method of microtremor measurement results, PGA is obtained from the PUSKIM website and the CTI value is obtained from the Centre for Ecology and Hydrology\u27s (CEH) website. The results showed that vs30 values ranged from 154.66 m / s to 260.80 m / s, CTI values ranged from 5.45 to 9.28 and PGA values ranged from 0.52 g to 0.67 g. The potential for liquefaction occurred throughout Sanden Subdistrict with a probability value of > 0.99 and the highest distribution of likuefkasi-prone settlements in the east of the research area.

No full textSafe is a tool used to store goods or assets and securities. Generally, a safe uses an analog lock made of metal and a rotary combination lock as a security system. However, the existing safe is not equipped with an information system that will notify the owner when the safe is accessed. This research was developed a safe security system using a digital key in e-KTP form which is detected by RFID (Radio Frequency Identification) sensor and the system was equipped with an information system based on nodeMCU ESP8266 to send notifications. The system designed consists of RC522 RFID module used to detect the e-KTP ID of the safe accesser. RFID connected to the nodeMCU platform which is an IoT device and connected to the cloud via wifi ESP8266. The information contained in the cloud from the IoT device and forwarded to the receiving smartphone as notification.
Applied Biomechanics: Prosthetic and Orthopaedics
No full textBiomechanics is closely related to engineering, because it often uses traditional engineering sciences to analyze biological systems. Some simple applications of Newtonian mechanics and/or materials sciences can supply correct approximations to the mechanics of many biological systems. Applied mechanics, most notably mechanical engineering disciplines such as continuum mechanics, mechanism analysis, structural analysis, kinematics and dynamics play prominent roles in the study of biomechanics. Usually biological systems are much more complex than man-built systems. Numerical methods are hence applied in almost every biomechanical study. Research is done in an iterative process of hypothesis and verification, including several steps of modeling, computer simulation and experimental measurements. Prosthetics and orthotics are clinical disciplines that deal with artificial limbs (prostheses) for people with amputations and supportive devices (orthoses) for people with musculoskeletal weakness or neurological disorders and some disability person. The development of prosthetics and orthotics disciplines is depend on development of science and engineering. The understanding of this multidiscipline field is important the advancement in this field. In this session i will overview the current development in prosthetics and orthotics field, expl ain a brief survey on its method, and discuss perspective for future trend and development

Study of Shark Kidney Histology (Carcharhinus sorrah)
No full textShark is a fish widespread in the tropical Indo-Pacific Ocean with a depth of 75 to 130 meters. Shark is a cartilaginous fish (Elasmobranchii). The fish is an ancient animal species that are still alive and also have different characteristics with bony fishes. Research on the histology of the shark\u27s kidneys is still rare. The purpose of this study was to describe the histology of the shark kidneys (Carcharhinus sorrah). In this study we used one individual shark (Carcharhinus sorrah) from Depok Beach, Yogyakarta. The method used in this research was paraffin method with Hematoxylin-Eosin staining. From microscopic observation, the kidneys consist of glomerular parts, proximal tubules, distal tubules and lymphoid tissue

The Technique Analysis of CO2 in Troposphere using AIRS
No full textCurrently global warming has become an international issue. One of the biggest contributors to global warming is carbon dioxide (CO2). CO2 gas is one of the most prominent gases of greenhouse gases or greenhouse gases in the atmosphere and has an important role in the Earth\u27s climate. Increased CO2 contributes more than 50% to the effects of global warming. Various methods and measuring instruments of CO2 concentration developed from optical sensors to measuring CO2 directly from space using satellites. Atmosphere Infrared Sounder (AIRS) is one of NASA\u27s six (6) instances launched on May 4, 2002 installed on the AQUA satellite. This instrument uses sounding technology that determines the vertical profile of CO2 from space. This instrument supports climate-related research and also in improving weather forecasts. AIRS data can be obtained online from the Giovanni Website at http://giovanni.gsfc.nasa.gov. Giovani is an application provided by NASA to make it easier to acquire, visualize, and analyze remote sensing data with ASCII data facilities that can be downloaded directly. The purpose of this research is to conduct CO2 analysis in Indonesia online using Giovanni Website year 2013-2016. Rendering data online shows the CO2 fluctuated every month, but yearly data shows the CO2 increased signifantly and the higest value in 2016, its reach 4.039 ppm. The results of CO2 analysis is expected to assist in the process of prevention or reduction of CO2 emissions in the air as one of the activities of environmental conservation
Fluorescence Imaging System Using High Power LED to Generate Oral Auto-fluoerscence of Sprague dawley Rat
No full textIt is difficult to distinguish oral cancer and normal oral mucosa in clinical examination. Hence, it is important to develop a diagnostic tool to aid clinical practitioners to examine and diagnose abnormalities in oral cavity. One of methods applied for this purpose was based on tissue auto-fluorescence. The purpose of this study was to develop a fluorescence imaging (FI) system using High Power LED (HPL) as excitation source. There were 3 HPL with different wavelengths used in this study, i.e. 385, 420, and 455 nm. The system was aimed to generate as well as to detect the auto-fluorescence effect of oral cavity in Sprague dawley rats. This study was done in 6 steps, i.e. development of FI system, early test of FI system using coconut oil, palm oil, olive oil, eucalyptus oil, and pure water as samples, followed by finishing of the system, image acquisition of oral cavity auto-fluorescence from 3 samples of Sprague dawley rats, and the last step was data analysis to determine the best wavelength of HPL for FI system developed in this study. Auto-fluorescence images were obtained by exposing samples by using HPL, then auto-fluorescence effect emitted by samples were captured using Canon EOS D600 camera. Auto-fluorescence intensity from images were analyzed using MATLAB R2008a. Results of this study showed that the best HPL wavelength used for the FI system was 385 nm that was captured with filter in the camera. The auto-fluorscence image produced by using HPL 385nm was showed the lowest intensities

the

are faced to several issues altering their con

effect.
In this plenary presentation, the French scientific
