Penggunaan sistem informasi dan teknologi yang cepat dirasa cukup penting dalam membantu proses belajar mengajar. Oleh sebab itu, diusulkan penggunaan platform E-Learning untuk membantu guru. Fitur yang diajarkan diarahkan untuk dapat melakukan pemberian materi, tugas, ujian, kuisioner, dan organisasi kegiatan. Para pengajar dilatih mengimplementasikan aplikasi online, seperti google drive, google form, untuk mendukung kegiatan bahan ajar, dengan sasaran guru guru SMA Tuban, Jawa Timur, Indonesia. Peserta merasa terbantu dengan sistem ini dan berencana mengaplikasikan kedalam proses pengajaran. Dari hasil training, para peserta merasa antusias terhadap pelatihan ini, dimana mereka mampu membuat, dan mempraktekkan fitur fitur yang ada di Google untuk membantu pekerjaan mereka. Dari hasil kuisioner tingkat kepuasan, sebanyak 15 dari 17 orang peserta pelatihan merasa terbantu dengan adanya pelatihan ini. Kemudian sebanyak 14 orang peserta juga merasa hasil pelatihan Information and Communication Technology yang diikuti relevan dengan permasalahan dan dapat dijadikan alternatif solusi yang membantu guru dalam proses kegiatan belajar. Peningkatan pemahaman juga dialami oleh peserta workshop sebelum dan setelah bergabung dengan kegiatan sosialisasi. dalam proses pembelajaran, merujuk pada data tingkat pemahaman yang diambil sebelum dan setelah pelatihan.
Along with the development of urban areas that continue to develop resulting in a land that was previously used to grow various kinds of vegetabels continues to experience narrowing and even converted into building houses. The hydroponic system can be an effective method for growing vegetabels without the availability of land. However, the implementation of this system still makes it difficult for hydroponic farmers who must at all times control water needs that are running out so quickly. This factor is caused by the evaporation process and amount of water needed by kale plants to carry out the process of photosynthesis as well as growth. The purpose of this research is to design a hydroponic system for cultivating water spinach using Water Level Control (WLC) to describe the distribution of air supply for hydroponics with air levels controlled by the system. This control system uses the Arduino as a mini computer to read the system, the HC-SR04 Ultrasonic sensor as a water level reader, 2 water pumps to fill and remove water. The results show that the plants can grow well in a hydroponic system with a controlled air level 25cm from the surface of the air reservoir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
