Tanaman bawang merah merupakan salah satu kebutuhan pokok, benih bawang merah yang baik adalah yang tumbuh secara optimal yang dipengaruhi beberapa faktor salah satunya adalah presentase kelembaban dan suhu tanah. Syarat tumbuh optimal benih bawang merah harus ditanam pada tempat yang kelembaban dan suhu tanahnya sesuai dengan yang dibutuhkan benih bawang merah. Berkembangnya teknologi saat ini dimungkinkan membuat sebuah teknologi dibidang pertanian. Pada penelitian ini dikembangkan sistem monitoring kelembaban dan suhu tanah dengan media penyiraman, alat ini berfungsi untuk mengukur dan menormalkan kelembaban dan suhu tanah untuk tanaman bawang merah. Pengukuran kelembaban tanah menggunakan sensor kelembaban tanah, pengukuran suhu tanah menggunakan sensor DS18B20. Sistem ini menggunakan Arduino Nano sebagai penggerak utama. Cara kerja alat ini adalah saat sensor kelembaban tanah mendeteksi kelembaban di bawah 50% maka mikrokontroler akan mengaktifkan water pump, saat sensor mengukur kelembaban tanah diatas 70% maka mikrokontroler akan memberi perintah water pump off. Seluruh informasi menghidupkan dan mematikan water pump akan ditampilkan pada LCD. Hasil penelitian nilai suhu tanah yang cocok sebesar 25°C-32°C dan nilai kelembaban tanah 50%-70%, untuk jenis tanah yang cocok untuk tanaman bawang merah adalah tanah aluvial yang tidak mudah kering sehingga nilai kelembaban tanah lebih stabil.

The Ideal

<p>Abstrak :</p><p>Kondisi lingkungan sering berubah-ubah membuat kondisi hewan ternak menjadi kurang produktif, terutama pada hewan ternak jangkrik. Selain dipengaruhi kondisi lingkungan yang berubah-ubah dan tidak menentu, penurunan hasil ternak jangkrik dipengaruhi oleh suhu dan kelembaban. Suhu yang ideal untuk ternak jangkrik ini berada pada kisaran 20°C-32°C. Sedangkan untuk kelembaban kandang berada pada kisaran 65%-80%. Untuk itu perlu alat untuk mengukur suhu dan kelembaban kandang jangkrik yang dapat mengawasi keadaan serta mengetahui kondisi kandang jangkrik itu sendiri sehingga dapat meningkatkan kualitas produksi jangkrik.</p><p>Berdasarkan permasalahan tersebut dibuat sistem monitoring ternak jangkrik. Dimana sistem ini dapat melakukan penyiraman secara otomatis jika suhu kandang jangkrik terlalu panas dan kandang terlalu lembab.</p><p>Hasil dari penelitian ini adalah <em>dashboard</em> informasi kondisi kandang jangkrik dengan sensor suhu dan kelembaban. Sistem ini pada menggunakan sensor suhu, kelembaban dan perangkat water pump yang didirakit pada mikrokontroler <em>NodeMCU</em>. Sedangkan Informasi ditampilkan secara <em>dashboard</em> monitoring dengan menggunakan framework Codeigniter.</p><p>_____________________________</p><p>Abstract :</p><p><em>Environmental conditions often change, making conditions for livestock to be less productive, especially for crickets. Apart from being influenced by changing and erratic environmental conditions, the decline in cricket production is influenced by temperature and humidity. The ideal temperature for crickets is in the range of 20 ° C-32 ° C. Meanwhile, the humidity of the cage is in the range of 65% -80%. For that, we need a tool to measure the cricket cage's temperature and humidity that can monitor the situation and know the condition of the cricket cage itself so that it can improve the quality of cricket production.</em></p><p><em>Based on these problems, a monitoring system for crickets was created. This system can do watering automatically if the cricket cage's temperature is too hot and the cage is too humid.</em></p><p><em>This research made a dashboard of information on the crickets cage's condition with temperature and humidity sensors. This system uses temperature, humidity sensors, and water pump devices, which are assembled on the NodeMCU microcontroller. Meanwhile, information is displayed in a monitoring dashboard using a Codeigniter framework.</em></p>

The article provides an overview of the principle of the pump D630-90, as well as methods for studying the real conditions of technical support to improve maintainability and optimize technological processes and systems. A technological process for the restoration of the shaft of a centrifugal water pump has been developed and an algorithm for managing it has been proposed, on the basis of which the system for energy-efficient management of the recovery area has been implemented. Also in the article some questions of use, metal-filled compound SK812, and also application of ultrasonic processing of a surface of a shaft of the centrifugal water pump of mark D630-90 are mentioned and considered. The developed technological process of pump shaft restoration showed that it is characterized by simplicity, it fits well into the production process of repair and can be widely used in repair shops.

In the introduction to this paper, the characteristics of Góreckie lake and the construction and operation of the wind-driven pulverizing aerator are presented. The purpose of this manuscript is to determine the efficiency of the pulverizing aerator unit in the windy conditions of Góreckie Lake. The efficiency of the pulverization aerator depends on the wind conditions at the lake. It was necessary to conduct thorough research to determine the efficiency of water flow through the pulverization segment (water pump). It was necessary to determine the rotational speed of the paddle wheel, which depended on the average wind speed. Throughout the research period, measurements of hourly average wind speed were carried out. It was possible to determine the efficiency of the machine by developing a dedicated mathematical model. The latest method was used in the research, consisting of determining the theoretical volumetric flow rates of water in the pulverizing aerator unit, based on average hourly wind speeds. Pulverization efficiency under the conditions of Góreckie Lake was determined based on 6600 average wind speeds for spring, summer and autumn, 2018. Based on the model, the theoretical efficiency of the machine was calculated, which, under the conditions of Góreckie Lake, amounted to 75,000 m3 per year.
