Abstract

In this research, the design and fabrication of microstrip antennas with circular polarization was is done to overcome the deviation of the antenna polarization angles, using microstrip line fed with a coaxial probe for Microwave Radio applications that work on the 11 GHz frequency band. To be able to produce circular or circular polarization on each patch of antenna arranged in an array, then it is done bit by bit (iteration) with the truncated corner technique on the edges and angles of the rectangular patch to produce an Axial Ratio of dec 3 deciBell.The type of substrate used in this study is FR4 with a relative dielectric constant value (Ɛr) = 4.58 and thickness (h) = 1.6 mm. By adjusting the cutting angle on the side of the patch, a circular polarization is generated with an Axial Ratio of a software simulation result of 1.065 dB and a bandwidth of 900 MHz at a frequency of 11 GHz. The final result of antenna fabrication tested at the Indonesian Institute of Sciences (LIPI) Electronics and Telecommunications laboratory in Bandung on May 29, 2019 consisted of a return loss value of -20,14 dB and VSWR 1.22 on the 11000 MHz frequency. The radiation pattern measurement results in a Half Power Beam Width value of 20 ° and an antenna gain of 7.02 dBi.

Abstract

Marketing tidak hanya diperlakukan sebagai penjahat utama karena peran nya dalam merangsang permintaan dan konsumsi yang tidak berkelanjutan, tetapi juga sebagai penyelamat lingkungan yang potensial melalui penerapan mekanisme pasar yang mengatasi masalah lingkungan yang dikenal sebagai “Green Marketing”. Work Coffee Indonesia adalah sebuah Coffee shop yang sudah terkenal di Kota Bandung dan merupakan salah satu pelopor Coffee shop yang melaksanakan Green Marketing. Untuk itu peneliti ingin mengetahui lebih lanjut mengenai bagaimana implementasi green marketing yang dilaksanakan pada Work Coffee Indonesia di Kota Bandung. Dengan menggunakan metode penelitian kualitatif dengan pendekatan wawancara kepada pengelola dari Work Coffee Indonesia. Hingga akhirnya didapati bahwa Work Coffee Indonesia menerapkan konsep green marketing sejak pertama kali berdiri. Dengan slogan “Less Waste, More Coffee” serta ”Zero Plastic” yang diimplementasikan dengan mengganti semua alat makan dan minum yang terbuat dari plastik sekali pakai, menajdi bahan yang bisa digunakan kembali. Selain itu, mereka juga mengolah sampah organik menjadi pupuk. Hal ini membuktikan bahwa mereka serius terhadap penerapan green marketing dan tentunya peduli terhadap lingkungan.
