Abstract

MESSI (Mesin dekafeinasi kopi) adalah mesin yang digunakan untuk menurunkan kadar kafein kopi. Penurunan kadar kafein ini menghasilkan kopi dengan kadar kafein yang lebih rendah. Pengecekan kadar kafein pada kopi dilakukan oleh pemilik MESSI (Mesin Dekafeinasi Kopi) dengan mengecek kadar kafein di laboratorium menggunakan spektofotometer. Kekurangan dari metode ini adalah harga alat yang relatif mahal karena menggunakan instrument yang rumit. Salah satu alternatif teknologi yang dapat digunakan untuk mengatasi masalah tersebut adalah dengan menggunakan pengolahan citra digital (digital image processing) dan menggunakan metode klasifikasi K-Nearest NeighBor untuk memudahkan pengguna mengetahui kadar kafein kopi berdasarkan data yang didapatkan sebelumnya. Digital Image Processing diimplementasikan pada platform android sehingga lebih mudah dan praktis saat digunakan. Aplikasi klasifikasi kadar kafein telah diimplementasikan pada smartphone Oppo Neo 7 dengan tingkat akurasi 90% pada data uji 30 serta 96,67% pada data uji 60 dan 90 untuk k = 3. Pada nilai k = 5 dan 7 memiliki nilai akurasi sebesar 93,33% dengan data uji 30, 96,67% dengan data uji 60 dan 90. Pengujian metode K-Nearest Neighbor dilakukan dengan membandingkan perhitungan manual dan perhitungan aplikasi. Hasil yang didapat adalah akurat, sehingga perhitungan metode K-Nearest Neighbor pada aplikasi sesuai dengan perhitungan secara manual.

Abstract

Starting from smartphones, netbooks, computers, to other devices, the internet has played an important role in shaping our new way of life. One new aspect that has emerged is online shopping, where people can now shop easily through online platforms. This phenomenon is often referred to as electronic commerce (electronic commerce or e-commerce). In business, it is important to implement e-commerce in marketing, sales and customer service activities. Many people think that marketing through the internet is more effective than traditional marketing methods because it overcomes various obstacles such as difficulty entering the market, country restrictions, and the lack of rules that apply in conventional marketing. This study is a quantitative research with a descriptive approach. Based on the research and debate that has been done, the components of overall income, business standards, the type of e-commerce media used, and the number of visitors to e-commerce media have a minimal negative effect on the growth of micro and small businesses. This conclusion is supported by the fact that the benefits derived from implementing e-commerce in the micro and small business sector are more focused on long-term benefits that are not directly related to increasing income directly.
