Abstract

The objective of this research is to study the implementation diffusion bonding process on tungsten and low carbon steel system with interlayer Ag-4% Cu, as well as investigate the influence of process parameters such as temperatur, initial pressure and heating time to the shear strength of the joint. Based on the result of shear test, initial pressure 48-144MPa has positive effect to the shear strength. Likewise by improving temperature of heating, it will improve the shear strength. The optimal shear strength is obtained at the temperature 9500C with maximal shear strength is 165 MPa and its bonding ratio 85%. The temperature 9500C and pressure of 144 MPa diffusion bonding has been successfully done with the heating time of 15 minute.Optical and stereomicroscopy on fracture surface after shear testing of the samples reveal tran granular fracture occur at the interlayer. Microstructure analysis at the interlayer reveals in variation microstructure as function of temperature, initial pressure, and heating time. The thickness of interlayer decrease with increasing the temperature, initial pressure and heating time. Other wise, the thickness of grain boundary and second phase area increase with the increasing the temperature, initial pressure and heating time. Based on the SEM/EDS examination, the element of Fe has the dominant distribution. There is accumulation of the element Fe on the limit area with tungsten. The distribution of the element of W, Ag and Fe increase with the increasing the heating time. Diffusivity of some atoms has been calculated based on SEM data at the interlayer. At 9500C, the diffusivity among the element of atom namely are D Ag to Fe= 0,00195 m2s-1, D Fe to Ag=0,02364 m2s-1, DAg to W=0,0061 m2s-1 , and DW to Ag= 0,025034 m2s-1.Keywords: Diffusion Bonding, material, Tungsten, steel, interlayer.

Abstract

Melinjo merupakan salah satu jenis tanaman perkebunan yang cukup banyak terdapat di Indonesia, khususnya di pulau Jawa. Melinjo banyak dimanfaatkan bijinya untuk diolah menjadi emping. Desa Mesoyi merupakan salah satu sentra penghasil melinjo di Kabupaten Pekalongan. Hal itu yang membuat di Desa Mesoyi terdapat banyak UMKM yang bergerak dalam bidang pengolahan melinjo menjadi emping. Namun pengolahan melinjo menjadi emping di banyak UMKM masih menggunakan cara tradisional sehingga produktivitasnya masih relatif rendah. Proses pembuatan emping dimulai dari penjemuran melinjo sehingga menjadi melinjo klatak, proses sangrai, pengupasan kulit keras, pemipihan dan terakhir dijemur untuk menjadi emping yang siap dipasarkan. Dalam penelitian ini akan difokuskan pada pembuatan paket teknologi tepat guna untuk proses pengelupasan kulit keras. Hasil yang diperoleh menunjukkan bahwa produktivitas alat pengupas kulit biji melinjo mencapai 39,6 kg per jam atau meningkat 6 kali lipat dibandingkan proses manual yang hanya mencapai 6,36 kg per jam. Dari segi konsumsi listrik, alat ini membutuhkan biaya Rp 831,37 per hari dengan asumsi penggunaan alat selama 6 jam per hari. Efisiensi alat pengupas kulit biji melinjo ini  adalah 86,5%

Abstract

C2C (consume r-to -consumer) e-commerce is currently growing fast in Indonesia. A C2C ecommerce website provides a marketplace in which buyers and sellers meet and make commercial transactions. Such a transaction requires high trust from both parties, since marketplaces typically have no or less sufficient mechanisms to assure that a transaction is safe. This paper analyses whether several factors that build trust has influence on one's willingness to participate in a transaction in a C2C e-commerce website. Factors that are considered are structural assurance, familiarity, perceived similarity, perceived reputation and perceived risk. Data are collected using a Likert-scaled questionanaire from 109 respondents i.e. The users of FJB (Forum Jual Beli, trading forum) Kaskus. Data are analysed using the SEM (Structural Equation Model) method. The results show that (i) perceived reputation has positive and significant influence on trust; and (ii) trust has positive and significant influence on participation
