Kediri there is two sources of water that is the Brantas River and groundwater. Currently the utilization of ground water is more dominant (95% of the total population use ground water) on the surface of the water, this is because the surface water has been polluted so that the necessary treatment before use. Kind of research method used is quantitative method, but the type of data used in this study, there are two types of primary data and secondary data. Potential surface water (river Brantas) reliable in the town of Kediri can reach 44.62 m3 / sec. Based on the projection, the potential for surface water in the town of Kediri can only provide water until 2022.

Technology is felt to be very helpful for humans in carrying out a series of daily activities, including the activities of farmers and chili plant business owners. Watering the plants every day makes the plants grow lush and healthy. However, sometimes these activities are neglected due to time constraints or other activities. To overcome this, it is necessary to build a system that can be used to assist automatic watering activities. This research discusses the use of Internet of Things technology to make automatic plant watering control devices using Android and Arduino UNO. The way this tool works is based on the soil moisture value and the testing temperature. The water pump will function when the soil moisture value is on a value scale of 75% with a temperature of 22 degrees Celsius and a water content >= 300 RH. By using soil moisture and temperature detection sensors, this tool will send a command signal to Arduino so that the relay driver is turned on so that the pump can distribute water as needed. From the tests carried out, it can be concluded that the tool made is able to carry out the function of watering plants automatically as expected. The water pump will automatically turn on if the temperature and soil moisture values match the settings in the system.

The hybrid process is carried out using the help of two randomly generated keys. The first key is a matrix with an 8bits value and the second key is a matrix with a binary value. The binary key is used to determine the Vigenere or Beaufort process, while the 8-bit key is used for modulus operations based on the Vigenere or Beaufort algorithm. At the test stage used a standard image that has an RGB color channel as a dataset. The quality of the cryptographic method is measured by several measuring instruments such as MSE, PSNR, and SSIM to determine the quality of encryption visually and the perfection of decryption, besides that it is used Entropy, NPCR and UACI to determine the probability of encryption resistance and quality against differential attacks. The TIC TOC function is also used to measure the computing speed of the encryption and decryption process. Measurement results using all measuring instruments indicate that the proposed method has very satisfying results and has fast computing.

Imam Bonjol Number 207. In order to offer top-notch educational services in the East Java region, UDINUS established a Study Program Outside the Main Campus (PSDKU) in the City of Kediri. Information technology is used by UDINUS to manage the company. beginning with student services, personnel, funding, and educational infrastructure. There isn't currently a system in place to gauge how effectively information technology administration is being used. In this study, a thorough analysis was done to establish how the COBIT 5 framework should be used for IT management. It is anticipated that by carrying out this research, it will be possible to learn more about the state of IT governance at UDINUS, Kediri City Campus, and offer recommendations to leaders for improvement in order to improve management. method for governing information technology at UDINUS's K...

Technology is felt to be very helpful to humans in carrying out a series of daily activities, including the activities of farmers and chili plant business owners. The activity of watering chili plants which must be routinely done every day allows chili plants to grow fertile and healthy. However, sometimes the routine work is neglected due to time constraints or other activities. In order for these problems to be minimized, it is necessary to build a system that can be used to assist automatic watering activities. This research discusses the use of Internet of Things technology to create an automatic plant watering control device using Android and Arduino UNO. This tool is useful for helping the work of farmers and owners of chili plants to carry out watering activities automatically. The workings of this tool are based on the soil moisture value. By using a so...
Strategi Optimasi Daya Dukung Sumberdaya Air Di Kota Kediri

Disisi lain kebutuhan terhadap sumber daya alam semakin meningkat, namun ketersediaan sumber daya jumlahnya semakin terbatas, sehingga terjadi persaingan yang tinggi untuk mendapatkan sumber daya alam tersebut. Persaingan yang terjadi ini menyebabkan tersisihnya sekelompok masyarakat yang secara ekonomi tergolong lemah. Air adalah kebutuhan mendasar bagi setiap manusia. Lebih dari 50% permukaan bumi ditutupi oleh perairan, namun demikian tidak semua air yang tersedia tersebut dapatkita konsumsi, karena kualitasnya tidak memenuhi kreteria untuk dikonsumsi. Oleh karena itu, air menjadi barang komersial saat ini. Berdasarkan hal tersebut, maka penelitian ini bertujuan untuk memperkirakan kebutuhan air baik domestik maupun non domestik di Kota Kediri sampai dengan tahun 2025 dengan metode proyeksi; mengetahui daya dukung sumber daya air diKota Kediri dengan analisis stati...

Gamifikasi berguna untuk meningkatkan pengalaman, menjaga kesetiaan pelanggan, penguatan merk dan melengkapi motivasi pembeli dan melakukan transaksi di e-commerce. Bentuk yang umum dari gamifikasi adalah pemberian reward bagi pelanggan dengan kondisi tertentu. Kondisi ini contohnya adalah lama menjadi pelanggan, besar transaksi, jenis transaksi. Masalah yang terjadi berkaitan dengan pemberian reward kepada pelanggan adalah reward yang tidak sesuai dan monoton atau mudah ditebak sehingga unsur kejutan yang menjadi salah satu elemen penting dari reward menjadi menurun kualitasnya. Penelitian ini bertujuan membentuk model gamifikasi yang tidak monoton menggunakan kecerdasan buatan dengan metode logika fuzzy. Logika fuzzy mampu membentuk perilaku reward yang dinamis sehingga meningkatkan kualitas reward yang diberikan kepada pelanggan. Input yang digunakan untuk menentukan reward adalah banyaknya tr...
