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
