Vannamei shrimp is a variety of shrimp that is very sensitive to changes in water quality, growth and life of vannamei shrimp which are directly affected by changes in temperature, salt content, dissolved oxygen, and pH (Hydrogen Potential) content in water. So far, vannamei shrimp cultivators know the quality of water by taking pond water samples with a certain period of time, uncertain natural conditions can make pond water quality change drastically if not maintained can inhibit growth or result in shrimp death.Making a monitoring system and controlling the quality of shrimp pond water using a water temperature sensor, salinity sensor, DO sensor and pH sensor installed on the Arduino Mega 2560 device, NodeMCU is used to receive and send data wirelessly, the system uses programming language c. This tool can be used to start the waterwheel automatically if it is within a certain threshold to maintain the temperature and dissolved oxygen in the pool water based on the value obtained from the sensor. The monitoring results obtained will be displayed to the user in real time through the interface and will be stored in the form of a text file on the storage media.
Perkembangan ilmu pengetahuan dan teknologi semakin mendorong upaya-upaya pembaruan dalam proses belajar mengajar, guru dituntut agar mampu menggunakan maupun membuat media pembelajaran yang lebih inovatif. SMP IT Cahaya Ummat Karangjati merupakan salah satu lembaga pendidikan Islam yang dalam proses pembelajaran masih menggunakan metode konvensional.

CV. Ida Ayu adalah sebuah perusahaan yang bergerak di bidang perdagangan umum seperti tas rapat dan blocknote. Tujuan dilakukannya penelitian ini adalah untuk merancang sistem informasi pendukung keputusan pembelian barang yang dapat menghasilkan informasi yang valid, cepat dan akurat dan untuk mengetahui bagaimana membangun sistem informasi pendukung keputusan pembelian barang yang efektif dalam peramalan penjualan. Sulitnya administrasi untuk merancang suatu sistem informasi pendukung keputusan pembelian barang yang valid berdasarkan peramalan penjualan dan membuat sistem informasi pendukung keputusan pembelian barang yang efektif dalam meramalkan penjualan pada CV. Ida Ayu Semarang. Pada aplikasi peramalan ini metode yang digunakan adalah metode moving average. Metode ini diperoleh melalui penjumlahan dan pencarian nilai rata-rata dari sejumlah periode tertentu, setiap kali menghilangkan nilai terlama dan menambah nilai baru. Hasil penelitian diharapkan dapat menunjukan bahwa perancangan sistem informasi pendukung keputusan pembelian barang berdasarkan peramalan penjualan berbasis web dapat membantu karyawan (administrasi) untuk meminimalkan terjadinya kesalahan pembelian barang dengan mempertimbangkan penjualan yang terjadi dalam periode tertentu. Jadi semua kegiatan penjualan serta pembelian barang di CV. Ida Ayu dapat berjalan secara efektif dan efisien.
CV Aintzane Mandiri is a company engaged in the field furniture. The Raw Material Manager at CV Aintzane is not yet optimal. Purchase Raw materials need to be considered because they will affect the maturity raw material needs and affect the production process. The information system for the supply of raw materials is needed by the company determination of expenditure, input of raw materials, and can minimize supply of raw materials for optimal use throughout the process production. Designing and building a procurement information system using raw materials Material Requirement Planning (MRP) method with programming language Microsoft Visual Basic 6.0, WAMP as server and MySQL as database. The results obtained from this information system can be obtained planning raw material requirements and production optimally and accordingly with company expectations. Keywords : Materials Requirement Planning, Computerized Accounting, Wamp, MySql
This study aims to build a library system application that can be used in the library of the Faculty of Engineering UNTAG Semarang based on an RFID card. From the background of the problem, namely, the process of borrowing and returning books is quite long, because to search for borrowed books the librarian must go to the bookshelf and look for the title of the book to be borrowed. The difficulty in making reports, because it is done after the library activities are finished, does not automatically coincide with the process of borrowing and returning services. Starting from the problems above, and paying attention to the number of daily visitors in the library that must be served, the authors propose to create a library service application using an RFID tag that can help the process of searching for member data and library books quickly.
