Sensor material characterisation for magnetometer application

Pengukuran dan gangguan medan magnet arus terus dan arus ulang-alik memerlukan penderia medan magnet yang mempunyai kepekaan yang tinggi dan stabil. Untuk menghasilkan penderia tersebut, ciri-ciri bahan magnet yang baik telah dikenalpasti. Beberapa jenis bahan magnet yang berbeza telah digunakan untuk mengkaji ciri-ciri dan kesannya terhadap medan magnet. Teras gelang yang diperbuat daripada bahan-bahan magnet tersebut direkabentuk dengan dimensi yang sama bagi membolehkan perbandingan dibuat dengan mudah. Selain itu, rod tunggal dan berkembar juga telah digunakan sebagai teras penderia fluxgate, untuk melihat prestasi setiap jenis penderia tersebut. Kedua-dua penderia tersebut telah diuji dengan menggunakan dua sumber bahan magnet iaitu bar magnet tetap dan solenoid dengan diameter dawai yang berbeza. Isyarat keluaran bagi setiap penderia fluxgate seterusnya diproses bagi mengenalpasti hubungannya dengan ketumpatan medan magnet

Does education engender cultural values that matter for economic growth?

Empirical research has shown that cultural values matter for economic growth and has specifically identified the achievement motivation as an aspect of culture that engenders economic growth. If specific cultural values engender economic growth, how then can societies promote them? This paper attempts to answer this question using the 2005 wave of the World Values Survey data for 43 countries. We test the contention that education significantly impacts the relative importance an individual places on economic achievement vis-à-vis traditional social norms. Results suggest that individuals with higher education levels attach higher importance to values related to autonomy and economic achievement as compared to conformity to traditional social norms. The results have an important implication for efforts to promote economic development; institutions and specifically public policy on education could be used to encourage people to adopt values that are considered important for economic development.Cultural Values, Education, Ordered Probit, Semi-Nonparametric Estimation

Fairness Evaluation in Cooperative Hybrid Cellular Systems

Many method has been applied previously to improve the fairness of a wireless communication system. In this paper, we propose using hybrid schemes, where more than one transmission scheme are used in one system, to achieve this objective. These schemes consist of cooperative transmission schemes, maximal ratio transmission and interference alignment, and non-cooperative schemes, orthogonal and non-orthogonal schemes used alongside and in combinations in the same system to improve the fairness. We provide different weight calculation methods to vary the output of the fairness problem. We show the solution of the radio resource allocation problem for the transmission schemes used. Finally, simulation results is provided to show fairness achieved, in terms of Jain's fairness index, by applying the hybrid schemes proposed and the different weight calculation methods at different inter-site distances

Praktik pemberian makan anak Balita tergolong kurang baik sebanyak 43,80 %, praktik pengobatan anak Balita tergolong kurang baik sebanyak 25,30 %, dan praktik kesehatan anak Balita tergolong kurang baik sebanyak 41,80 %. Tingkat konsumsi energi kurang baik pada anak Balita sebanyak 60,30 %, dan tingkat konsumsi protein kurang baik pada anak Balita 54,60 %. Simpulan penelitian, faktor yang berhubungan dengan status gizi buruk pada Balita umur 7-9 bulan yaitu pola asuh pemberian makan Balita, tingkat konsumsi energi, dan protein Balita. The research problem was whether the factors associated with underweight nutritional sta-tus in children under five. Research purpose to determine the factors associated with under-weight nutritional status in toddler. Survey method in infants aged 7-59 months in the re-gion of Leuwimunding health center amounts 200 samples, using cluster random sampling. Data collected by interview and direct weight measurement using bathroom scales. Data analysis by chi square. The results showed the nutritional status of toddler were classified as underweight as 31.40 %, which was experiencing chronic diarrhea 14.90% and pneumonia 8.80%. Unfavorable practice of toddler feeding as 43.80%, unfavorable treatment practices of toddler as 25.30%, and unfavorable health practices of toddler as unfavorable as 41.80% . The rate of energy consumption is not good for toddler as much as 60.30%, and the rate of protein consumption wass less good in 54.60% of toddler. The conclusions, factors associ-ated with underweight nutritional status in infants aged 7-9 months were toddler feeding, level of energy consumption, and protein toddlers

Antenna with artificial magnetic conductor for wireless application

— This paper discussed the recent works on Artificial Magnetic Conductor (AMC) with the antenna. Two different application for antenna with AMC have been discussed. The first application is the antenna with AMC that has been used for RFID system to detect the metal object. Without incorporating AMC with antenna the system cannot be detected. When the AMC is attached with the RFID Tag antenna the system is back to normal where longer distance is achieved. The second application is used for flexible AMC using textile material for signal transmission enhancement. Using two antennas for on body application the system has been tested using AMC and without AMC. It shows that the transmission is better when there is an AMC attach to the body compared without AMC. Index Terms — Artificial Magnetic Conductor, high impedance surface, metamaterial, reflection phase

Karbon Monoksida (CO) pada Ibu Hamil (Perokok Pasif) terhadap Kejadian Bayi Berat Lahir Rendah (BBLR) di Wilayah Kabupaten Kuningan

Bayi berat lahir rendah (BBLR) masih menjadi permasalahan di negara berkembang. Berdasarkan laporan riset kesehatan dasar tahun 2013 menunjukan bahwa proporsi  BBLR di Indonesia yaitu 10.2 %. Paparan asap rokok dapat menjadi faktor resiko terjadinya BBLR. Berdasarkan Riskesdas (2013) sebesar 85% rumah tangga Indonesia terpapar asap rokok. Tujuan penelitian ini adalah untuk mengetahui hubungan kadar karbon monoksida (CO) hamil perokok pasif dengan kejadian BBLR. Jenis penelitian menggunakan desain kasus kontrol. Populasi penelitian adalah ibu hamil yang melahirkan pada periode waktu Januari 2017 sampai dengan Maret 2018 di wilayah Puskesmas Manggari Kabupaten Kuningan. Adapun besar sampel dalam penelitian yaitu total sampling sebanyak 27 orang dengan ratio 1:1. Sehingga jumlah sampel sebanyak 54 orang. Selain itu penelitian ini didukung dengan data kualitatif menggunakan kombinasi (mix method) model concurrent-embedded. Instrumen penelitian berupa kuesioner dan alat pengukur karbon monoksida (CO) yaitu Micro + ™ Smokerlyzer. Analisis data dilakukan melalui analisis univariat, bivariat (uji chi-squre) dan analisis data kualitatif.  Hasil penelitian menunjukan 54,2 % ibu yang memiliki kadar CO kategori berbahaya mengalami kejadian BBLR. Sebanyak 46.7 % ibu yang memiliki kadar CO kategori normal mengalami kejadian BBLN.  Perbedaan proporsi berdasarkan kategori kadar CO pada ibu antara kelompok kasus (BBLR) dan kontrol (BBLN) tidak berbeda secara signifikan (p;0,584; OR:1,4; 95%CI:0,460-3,964)

What determines workers’ preferences for efficiency over equity wages?

What makes workers consider it fair for wages to be indexed on job performance or efficiency? In this paper we attempt to answer this question using the 2005 wave of the World Values Survey data for 43 countries to investigate what socio-economic characteristics condition employees’ preference for efficiency over equity wages. Our results suggest that employees’ preference for efficiency wages increases with education and globalization while it decreases with unemployment, income inequality and income tax rates. Given that conventional economic theory demonstrates the importance of labour efficiency, which improves when workers are remunerated according to their efficiency, for economic growth; our results suggest that institutions and specifically public policies that promote education, and globalization, along with policies that reduce unemployment, income inequality and income tax rates could be used to promote efficiency-based wages.
