Selection of High Strength Encapsulant for MEMS Devices Undergoing High Pressure Packaging

Deflection behavior of several encapsulant materials under uniform pressure was studied to determine the best encapsulant for MEMS device. Encapsulation is needed to protect movable parts of MEMS devices during high pressure transfer molded packaging process. The selected encapsulant material has to have surface deflection of less than 5 ?m under 100 atm vertical loading. Deflection was simulated using CoventorWare ver.2005 software and verified with calculation results obtained using shell bending theory. Screening design was used to construct a systematic approach for selecting the best encapsulant material and thickness under uniform pressure up to 100 atm. Materials considered for this study were polyimide, parylene C and carbon based epoxy resin. It was observed that carbon based epoxy resin has deflection of less than 5 ?m for all thickness and pressure variations. Parylene C is acceptable and polyimide is unsuitable as high strength encapsulant. Carbon based epoxy resin is considered the best encapsulation material for MEMS under high pressure packaging process due to its high strength.Comment: Submitted on behalf of EDA Publishing Association (http://irevues.inist.fr/EDA-Publishing

Relasi antara Penggunaan Android dan Perubahan Sosial Perdesaan

Social changes is all changes on social institutions within community which impacting on its system including values, norms and patern of behaviour between groups in community, technology is one of the cause. Technology of media cq Android pressumed will give impact on traditional rural so- cial system, thus these mixed-method research intended to study how far the impact of the USAge of Android on rural social changes.The present of internet followed by the more personalized Android in the rural community has made a transformation on interaction dimension between member of community both in Babakan village as urban-rural, and Petir as rural-village. The ownership and USAge of Android between member of community today has various of meanings, whether to build peer-relation,tighten the family cohesion or to support the economic activities. The social change as impact of the USAge of Android apparrently only occurs on interaction dimension without changing the structural or the cultural dimension. Research found, the prolonged social norms which has been rooted and maintaned by the community still able to work as social control mechanism, however the research shows the indication that the rationlisation on individual is ongoing, this may more or less loosen the social cohesion of rural community

The result of research conducted in mind that of the thirteen factors the role of psychological factors only heuristic, representativeness, availability, framing effects, and loss aversion in financial decision-making Kalrez Petroleum (Seram) Ltd. company

Gap Analysis (Tax Gap) Of Land And Building Tax Of Urban And Rural Sector (Pbb P2) Revenues In Kediri City

This study will reveal what makes the gap on the Land and Building Tax of Urban and Rural Sector (PBB P2) revenues in Kediri. PBB P2 is one kind of local taxes which was regulated in Law No. 28 of 2009 on Regional Taxes and Retribution. Kediri is one of cities that had been collecting PBB P2 through Regional Financial Management Body of Kediri (Dispenda Kediri) since the beginning of 2013. This research used descriptive research with qualitative approach. Study\u27s result shows that tax gap phenomenon is happening in PBB P2 revenues at Kediri. Tax gap itself consists of three variables, they are non-filling gap, underreporting gap, and underpayment gap. All these variables are detected in the PBB P2 revenues in Kediri with different percentage of its variables. Research\u27s result also shows how Dispenda Kediri didn\u27t use the tax gap theory to analyze the element of PBB P2 revenues. By knowing the variables contained in tax gap, Dispenda Kediri will be easier to set proper strategies to reduce the amount of tax gap in PBB P2 revenues

Analisis Efektivitas Penerimaan Bea Perolehan Hak Atas Tanah dan Bangunan dan Kontribusinya terhadap Pendapatan Pajak Daerah (Studi pada Dinas Pendapatan Daerah Kota Malang Periode 2011-2014)

BPHTB is a potential local tax at Malang. Realization BPHTB at Malang has always managed to exceed the planned target, but the other still a lot of problems that make collecting BPHTB not optimal. Percentage contribution of BPHTB to the Local Tax Revenue is great, BPHTB become a tax that dominates Total Local Tax Revenue. The purpose of this study is to analyze the effectiveness of BPHTB, and it contribution to the Local Tax Revenues in Malang. The type of research is descriptive with qualitative approach. The results show that the level of effectiveness of BPHTB in Malang during the years 2011-2014 has been very good with an average 121.94%, but based on the survey results in mind that a lot of potential BPHTB that has not been optimized. Contribution of BPHTB to the Local Tax Revenue at Malang in 2011-2014 has been good with an average 44.49%, This happens because the transaction on acquisition of land and buildings at Malang high, it causing of continued increase in property prices at Malang. The situation is feared impact on poor people increasingly can not afford to buy housing at Malang

Improving the Nutritional Status of Preschool Children by Supplementing Adequate Calories

Telah dilakukan penelitian perbaikan gizi di PT Perkebunan XI, Kebun Karet, Kabupaten Sukabumi. Anak prasekolah umur 1-5 tahun dibagi dalam 4 kelompok, dengan perlakuan sebagai berikut: Kelom­pok I adalah kelompok kontrol; Kelompok II diberi makanan tambahan kalori tinggi (C); Kelompok III diberi makanan tambahan kalori tinggi protein tinggi (CP); dan Kelompok IV diberi makanan tam­bahan kalori tinggi protein tinggi ditambah pendidikan gizi intensif (CPE). Setiap kelompok terdiri dari 32-35 anak. Pemberian makanan tambahan dilakukan setiap hari selama 4 bulan (122 hari). Makanan tambahan C mengandung rata-rata 500 kalori dan 4 g protein, sedangkan makanan tambahan CP me­ngandung rata-rata 500 kalori dan 20 g protein. Lain daripada itu pengobatan sederhana terhadap infek­si diberikan kepada setiap anak pada semua kelompok. Konsumsi kalori sangat rendah dibandingkan dengan konsumsi protein. Dengan pemberian tambahan kalori yang cukup, tingkat keadaan gizi bertambah baik secara nyata. Perbaikan keadaan gizi pada ke­lompok yang diberi makanan tambahan C sama dengan pada kelompok yang diberi tambahan makanan CP dan CPE. Pengaruh pendidikan gizi terhadap perbaikan keadaan gizi belum tampak sesudah 6 bulan perlakuan. Hampir 50 % anak dijumpai menderita infeksi, dan jumlah ini menunjukkan kecenderungan berkurang selama program berlangsung
