Abstract

Optical Add-Drop Multiplexer (OADM) menggunakan Fiber Bragg Grating (FBG) merupakan passive optical device dalam sistem transmisi serat optik yang dapat melakukan multiplexing, demultiplexing, filter, dan routing pada teknik Dense Wavelength Division Multiplexing (DWDM). Hasil analisis penerapan OADM menggunakan FBG dalam sistem serat optik menunjukkan pada spasi kanal 100 GHz terjadi penurunan panjang grating 1,6048 mm sampai dengan 0,1646 mm, penurunan nilai panjang grating tersebut menunjukkan semakin besar jumlah kanal transmisi panjang gelombang yang ditransmisikan. Pada hasil analisis penurunan panjang grating dan perubahan indeks bias grating sebesar 10-3, 10-4, dan 10-5 terjadi penurunan reflektivitas dan peningkatan transmitivitas sehingga juga dapat memberikan kontribusi dalam peningkatan jumlah kanal transmisi. Analisis crosstalk pada spasi kanal 100 GHz menunjukkan nilai crosstalk yang kecil antara -25,1282 dB sampai dengan -20,4846 dB, terbukti bahwa OADM menggunakan FBG pada sistem serat optik dapat mengurangi crosstalk.Kata Kunci—OADM, FBG, DWDM, reflektivitas, transmitivitas, crosstalk.I.

Abstract

 Automatic face detection in frontal view for thermal images is a primary task in a health system e.g. febrile identification or security system e.g. intruder recognition. In a daily state, the scanned person does not always stay in frontal face view. This paper develops an algorithm to identify a frontal face in various standing body-pose. The algorithm used an image processing method where first it segmented face based on human skin’s temperature. Some exposed non-face body parts could also get included in the segmentation result, hence discriminant features of a face were applied. The shape features were based on the characteristic of a frontal face, which are: (1) Size of a face, (2) facial Golden Ratio, and (3) Shape of a face is oval. The algorithm was tested on various standing body-pose that rotate 360° towards 2 meters and 4 meters camera-to-object distance. The accuracy of the algorithm on face detection in a manageable environment is 95.8%. It detected face whether the person was wearing glasses or not.

Abstract

Heartbeat and body temperature are vital signs that routinely checked by the hospital to determine the clinical signs are used to confirm the diagnosis of a disease. In the process, heartbeat and body temperature checking in some hospitals still use manual system where a nurse had to come to the patient room to check and record heartbeat and body temperature of the patient. This system is less effective because it takes a lot of time. In this research has been created a monitoring system of the heartbeat and body temperature wirelessly. The system uses pulse sensors to detect the heartbeat, LM35 to detect body temperature, for data processing using Arduino nano and utilize NRF24L01 as wireless data transmission media. This system detects heartbeat and body temperature in real time. The processed data is then displayed on an application. The information provided on the application include heartbeats per minute, body temperature, and indicators of the condition of the heartbeat and body temperature of the patient. The application also have a features that can store heartbeat and body temperature at a certain time. Based on the test results, the success rate of the system in detecting heartbeats is 97.17%. While success rate of the system in detecting body temperature is 99.28%. For data transmission, the system can perform data transmission smoothly at a maximum distance of 15 meters to the barrier.

Abstract

The development of science and technology makes the quality of human life is growing, the processing industry and agricultural estates are also growing rapidly. One of the stages in the processing of agricultural products and plantations is the selection of products based on quality, such as fruit maturity level. The process of selecting agricultural products and plantations is highly dependent on the human perception of the fruit color composition factor. Apple is one type of fruit that is very popular and is often consumed by the community, both from the young to the old. Apples also contain vitamins needed by the human body, including vitamins A, B1, and C. So, it can be said that apples are a very popular fruit because the benefits are very abundant. But apple lovers are often confused in terms of choosing apples that have ripe maturity. Sometimes apple entrepreneurs still use the manual way to distinguish the maturity of apples, while the way that is done by the tenega man is often inaccurate and different in its determination. The difference is due to differences in perceptions on everyone. Therefore built a tool that can make the selection of apples based on quality, especially color automatically. So that will be able to produce a more accurate grouping of apples, which further simplify the packaging process and also save time, effort and cost. Design This tool uses RGD LDR and DHT11 as sensors to read the maturity of apples. RTC 1307 is used as a timer to send data from sensor, arduino nano as microcontroller and NRF24L01 as a data transmission device between two transmitter nodes and receiving node.
