Konsep customer relationship telah berubah menjadi customer engagement, yang kini dikenal sebagai konsep Customer Relationship Management (CRM). Karakteristik CRM mengakomodir tiga hal: pemasaran, penjualan, dan layanan. Industri pendidikan memiliki karakteristik paling kuat pada layanan karena keterikatan pelanggan untuk waktu yang cukup lama pada institusi pendidikan. Kepuasan pelanggan akan memberikan rekomendasi positif kepada keluarga dan kerabatnya. Sebaliknya ketidakpuasan pelanggan akan membawa rekomendasi kurang baik. Dengan demikan, pelayanan pelanggan selama masih terikat dengan perusahaan sangat menentukan keberlangsungan bisnis perusahaan selanjutnya. Penelitian dilakukan menggunakan model EUCS (End User Computing System) dimana hipotesisnya diuji berdasarkan análisis korelasi dan análisis regresi serta menggunakan IPA (Importance Performance Analysis) untuk melihat hal-hal yang perlu ditingkatkan dengan menghitung gap analisisnya. Berdasarkan análisis korelasi, semua hipotesis H1 (ada hubungan) diterima dan berdasarkan análisis regresi, semua hipotesis H1 (berpengaruh) diterima. Dan berdasarkan IPA, tiga dari lima variabel perlu peningkatan sebagai prioritas pertama. Sementara untuk prioritas kedua semua variabel perlu ditingkatkan.

Cell phones are now a cheap means of wide-ranged wireless communication. One feature widely used is the short message service (SMS). The cellular communication system is more appropriate for long-distanced applications than high speed data transfer. This study aims to develop a GSM modem interface with AVR microcontroller using C programming language. The tools controlled by the microcontroller system can gain more benefit if it is linked with GSM mobile communication system. The results of this study can be applied whether in a remote monitoring system, remote control system, or communication between the microcontroller via SMS. Many additional benefits can be obtained for the tools controlled by the microcontroller when connected to a GSM system.
