Abstract

The sound is an important vital information that it relies to recognize the character when lessening to it. Therefore, the audio signal adopted into many important applications. Sound forming and synthesizing in addition to distinguishing the speaker are so important in fields of digital signal processing. In this paper, work is done to represent acquired acoustic signal based on mathematical techniques. Mathematical representation provides  deal with the sound signal which lead to smoothing, amplification or compression, in addition to the sound filtering process. In the proposed algorithm, polynomials of various degrees were adopted as a mathematical representation for speech signal, then the retrieved speech was studied based on level of clarity and the possibility of adopting it as an alternative signal in terms of the proximity to the original sound and the amount of noise added to it.  The results shows that the proposed algorithm with degree of polynomial 20 and segment length 25 had the best sound representation and so closed to the original, which clearly seen from the evaluation parameters (Correlation=0.9993, Mean squared error(MSE) =1.32e-06, Standard deviation(STD)=1.80e-05 and the Euclidean dimension(ED) =0.1703).

Abstract

Kesehatan merupakan salah satu dari parameter kesejahteraan manusia. Jika seseorang sakit, mereka akan mencoba memeriksakan diri ke dokter. Banyak penyakit memiliki gejala yang tidak spesifik, karena itu perlu pengetahuan untuk mendiagnose sebuah penyakit. Dokter merupakan faktor kunci dalam sistem pengobatan. Usia, gaya hidup dan polutan dapat menyebabkan penyakit degeneratif. Para degeneratif memerlukan perhatian seksama dengan pemantauan rutin. Sistem pengobatan konvensional masih membutuhkan interaksi dengan dokter secara langsung. Para dokter mendengarkan keluhan, bertanya, mendiagnosa, dan memberikan perawatan medis. Di sisi lain dengan terbatasnya jumlah dokter, distribusi yang tidak merata, dan jarak yang jauh menyebabkan praktek medis konvensional tidak efisien. Dokter dapat menerima hasil, mendiagnosa dan memberikan saran secara jarak jauh menggunakan teknologi informasi dan komunikasi. Layanan ini dapat mencakup pula kasus-kasus darurat dan layanan pendampingan.Berdasarkan masalah di atas, tujuan penelitian ini adalah terutama untuk merancang dan membangun aplikasi yang dapat digunakan untuk komunikasi antara dokter dan pasien berbasis pada jaringan TCP/IP. Penekanan aplikasi dalam berbagai data yang dikirim (teks, audio, video dan file).Sistem pemeriksaan secara jarak jauh dapat diwujudkan dengan menggunakan bahan dan alat yang telah dikenal dengan baik oleh pengguna umum. Kesulitan untuk mengakses alamat IP dalam sistem ini dapat ditangani oleh penambahan jalur khusus virtual semisal Hamachi. Kecepatan komunikasi melalui LAN memberikan hasil sangat baik, memenuhi persyaratan  hampir semua fasilitas yang ada, sedangkan kecepatan komunikasi melalui internet sudah cukup untuk beberapa persyaratan sistem terutama yang yang tidak memerlukan kemampuan real-time.

Abstract

The potential of renewable energy in Indonesia is very large with a total of 3,643.0 GW. One of them is wind energy, the huge potential of wind energy which is 154.9 GW is very wasted if it is not optimized as well as possible. The biggest obstacle to utilizing wind potential is low wind speed in some areas in Indonesia. So an effective generation system is needed to produce efficient output. A permanent Magnet Synchronous Generator (PMSG) is very suitable for use in areas of potential low-speed winds because low rotation can produce good efficiency. The output value of the Permanent Magnet Synchronous Generator (PMSG) is currently still low and can still be improved, for this research will analyze the broad influence of the cross-section of the winding wire on the stator on the efficiency of the 18 slots 16 poles Permanent Magnet Generator with rotational speed based on wind speed in Indonesia. Variations were carried out on a cross-sectional area of 0.6 mm2-3.6 mm2 winding wire and rotating speeds of 500 rpm, 750 rpm, and 1000 rpm. By using MagNet Infolytica 7.5 software based on Finite Element Method (FEM) to obtain output values in the form of voltage, current, and torque.  For efficiency values, data is reprocessed using Microsoft Excel. The results of this study show that the value of efficiency increases. The best efficiency produced when the rotating speed is 500 rpm is 97.04% at a cross-sectional area of 2.6 mm2 winding wire, for a rotating speed of 750 rpm the efficiency reaches 97.24% at a cross-sectional area of 2.4 mm2 winding wire and at a rotating speed of 1000 rpm the resulting efficiency is 97.16% at a cross-sectional area of 2.4 mm2 winding wire.

Abstract

LEDs in lighting systems have been widely used, including public street lighting systems. However, the selection of public street lights in Indonesia often does not use lumen calculations and light dimming technology. This study aims to improve energy consumption efficiency by replacing existing lamps with LED lamps according to the lumen calculation method and using a smart system in the form of automatic dimming of the lamps. The research study was carried out in two stages: the measurement of illumination using a lux meter and the analysis of energy consumption between the existing and the replacement. The replacement scenario is to replace the existing lamps with LED lamps equipped with an automatic dimming system based on lumen calculations. The lighting level is adjusted to Indonesian lighting standards, SNI 7391:2008, 2 to 5 lux. The result of the study is that carrying out a replacement scenario can increase energy consumption efficiency by 77.95%.

Abstract

Penghematan pemakaian energi menjadi, karena cadangan energi makin berkurang. Ada dua cara yang dilakukan untuk menghematkan pemakaian energi, dalam hal ini energi listrik yaitu, mengurangi waktu pemakaian dam memperkecil daya listrik peralatan yang terpakai. Penelitian ini merancang sistem kendali pemakaian energi listrik pada ruang kuliah. Monitoring dilakukan dengan sensor arus, sensor untuk mengetahui  apakah AC, infokus dan lampu hidup ketika ruang kuliah tidak digunakan. Hasil pembacaan sensor disampaikan melalui Xbee dan Arduoino.  Ruang kelas dibuat dalam sebuah proyotype dengan beban listrik sebuah lampu. Pengontrolan dapat dilakukan melalui komputer untuk menghidupkan atau mematikan peralatan dalam ruangan kuliah. Dari hasil pengujian ada dua hal yang mempengaruhi penerimaan sinyal pada receiver, yaitu jarak dan kebebasan terhadap transmiter. Dari hasil pengukuran semakin jauh jarak antara transmiter dan receiver maka waktu delay makin besar. Pada jarak 5 m waktu delay hanya 5 detik, untuk jarak 30 m waktu delaynya adalah 60 detik dan pada jarak 50 m waktu delaynya menjadi 121 detik. Sedangkan jika ada penghalang antara transmiter dengan receiver waktu delay pada jarak 10 m adalah 10 detik, jarak 30 m menjadi 90 detik dan ketika jaraknya 50 m waktu delay adalah 191 detik. Didapatkan hasil semakin jauh jarak antara transmitter dan receiver maka semakin lama waktu pengiriman. Hal ini dapat dipengaruhi oleh adanya pantulan dan loss data oleh udara.
