One of them is the internet of things technology that provides benefits in life among them in monitoring the security. Security is one of human need. One of them is safety on a motorcycle. The number of motorcycles in Indonesia alone is quite a lot. But not yet balanced with adequate security system, so that the theft of motorcycle was still high enough. Many ways that can be done by breaking a burglar motorcycle ignition lock, one of which is by using a special key. In addition, motorcycle theft may occur due to lack of responsiveness to inform the surrounding environment, so thieves can bring a motorcycle freely. So the need for motorcycle security is higher, and motorcycle owners feel safe about the vehicle. This security system using microcontroller components, ultrasonic sensors, PIR sensors and relay integrated with IoT platform that cayenne using internet network mounted on a motorcycle. So that the motorcycle owner is able to monitor the safety of his motorcycle even from long distance as long as there is an internet network connection.

Pendekatan deskriptif digunakan guna mendapatkan gambaran bagaimana persepsi responden terhadap implementasi kebijakan, kualitas pemasaran jasa dan tingkat kepuasan para pengguna jalan tol. Pendekatan asosiatif digunakan guna mengetahui hubungan antara ketiga variabel yang telah disebutkan di atas. Teknik pengambilan sampel menggunakan Teknik Probability Sampling. Sampel yang digunakan dalam penelitian ini yaitu 130 orang yang merupakan pengguna jalan tol di Pulau Jawa. Untuk menguji instrumen penelitian dengan menggunakan Uji Validitas dan Uji Reliabilitas. Pengujian hipotesis dilakukan dengan menggunakan Uji Regresi Berganda. Hasil penelitian ini menunjukan bahwa Penerapan kebijakan pembayaran non tunai jalan tol pada pelanggan pengguna jalan to di Pulau Jawa telah dilaksanakan cukup baik. Sumber daya yang dimiliki oleh pengelola jalan tol cukup mumpuni terutama sumber daya manusia sebagai unsur utama dalam melakukan manajemen terhadap sarana yang digunakan sebagai alat pembayaran non tunai. Manajemen pemasaran yang dilakukan oleh pihak penyedia layanan produk pembayaran non tunai pada jalan tol, pada prinsipnya telah dilaksanakan dengan cukup baik. Manajemen pemasaran yang paling dominan dalam memberikan mendukung terlaksananya kebijakan tersebut adalah faktor harga.

Salah satu persoalan utama yang terjadi dalam penyediaan air irigasi adalah semakin langkanya ketersediaan air (water scarcity) pada waktu-waktu tertentu. Pada sisi lain permintaan air untuk berbagai kebutuhan cenderung semakin meningkat sebagai akibat peningkatan jumlah penduduk, beragamnya pemanfaatan air, berkembangnya pembangunan, serta kecenderungan menurunnya kualitas air akibat pencemaran oleh berbagai kegiatan.
