Abstract

Unwanted hole in metal sheet that use for vehicle body or structure is proved dangerous situation. To prevent disaster this hole needs to be found before its installation, or other wise it will be time and money consuming once its found when already finished installation. Therefore, an inspection using sensor for metal sheet is recommended to prevent this problem. In this paper, we proposed a new sensor using radio wave propagation to detect holes in metal sheet. We propose to use RSSI methods to detect hole based on electromagnetic wave propagation signal strength. Using this method we success to detect 8mm hole diameter in metal sheet with 1mm thickness. Using this method, we transmit electromagnetic wave energy at about 20 dBm, and we receive with average -27.53 dBm for iron sheet and -23.13 dBm for aluminum sheet.

Abstract

Pada setiap rumah sakit atau fasilitas medis terdapat perawat yang bertanggung jawab atas perawatan suatu pasien. Para perawat ini mengawasi keadaan pasien selama masa pemulihannya atas penyakit atau cidera yang dideritanya. Pasien dalam kondisi tertentu terkadang membutuhkan bantuan perawat, bahkan dalam situasi gawat darurat pasien membutuhkan pertolongan segera. Sistem pemanggil perawat ini dirancang agar pasien bisa melakukan panggilan ke perawat dengan hanya menekan suatu tombol. Ketika pasien menekan tombol akan muncul indikasi pada suatu layar LCD yang terdapat di ruang perawat untuk menunjukkan pasien dari ruangan mana yang membutuhkan bantuan. Pengujian prototype alat dilakukan dengan membuat simulasi panggilan dari tempat tidur pasien dengan menekan tombol CALL 1 dan dari toilet dengan menekan tombol WC 1. Sistem merespon dengan segera menampilkan pemanggil secara real time di LCD dengan tidak ada delay waktu. LCD menampilkan pemanggil secara bergantian dan yang ditampilkan terlebih dahulu adalah yang pertama melakukan panggilan (metode FIFO).

Abstract

According to a report from the United Nations estimates that by 2030 about 800 million people worldwide will suffer from hunger. To combat this problem the agricultural production needs to be increased by at least 60%. One of many parameters that need to be monitor to increase agricultural output was soil PH level. Soil PH is very influential on the development of rice plants, where high acidity soil will make plant unhealthy and die. In order to be able monitor soil PH level, we need low cost and long life WSN node that can monitor soil PH level. In this paper we have manage to a long life WSN node that can monitor PH level with low cost at about less than 15 US dollar. this WSN node PH meter are using couple of aluminum and lead couple electrode as sensor, and its deviation at about 0.73 compare with ATC 009 PH meter which only 0.55. This device also capable to operate for so long (which is 2 years operational time) using 0.1 duty cycle scheme.

Abstract

one of the advantages of Wireless Sensor Network would be its ability to reduce cost of communication system using node to node communication. Because of many things data transfer is Wireless Sensor Network operation sometimes has disturbance. A routing algorithm is a network coding that intends to enhance network performance for better operation with or without any disturbance. Fuzzy TOPSIS and SAW as MCDM algorithm is proposed for routing algorithm in Wireless Sensor Network operation. From our simulation both SAW  and Fuzzy Topsis algorithm can be used in network coding (routing) to provide better QOS for Wireless Sensor Network compare with shortest path routing. For delay it perform better at about 2/3 (shortest path routing 50 millisecond, both SAW and Fuzzy Topsis algorithm 33 millisecond), and for packet loss at about 3/4 (shortest path routing 21 bit loss, both SAW and Fuzzy Topsis algorithm 16 bit loss). From our simulation both SAW and Fuzzy Topsis algorithm algorithm has benefit which is lower delay and packet loss but at higher cost which is more hopping for communication channel (shortest path routing 3 hopping, both SAW and Fuzzy Topsis algorithm 5 hopping)
