Sekolah sebagai salah satu lembaga pendidikan yang berfungsi untuk melaksanakan proses belajar mengajar diharapkan bisa mengikuti perkembangan dalam bidang teknologi informasi. SMP Karel Sadsuitubun Langgur saat ini proses pengolahan data nilai akademiknya masih belum optimal. Penyimpanan data dan pengolahan data saat ini masih dilakukan secara konvensioanl sehingga tidak terlalu optimal. Tujuan penelitian ini adalah agar mengetahui cara pengolahan data nilai yang sedang berjalan, membangun sistem pengolahan data nilai berbasis web, dan mengimplementasinya. Metode penelitian yang digunakan adalah observasi, wawancara, dan studi pustaka yang berhubungan dengan kasus yang terjadi. Sistem Pengolahan data nilai ini menggunakan model pengembangan watterfall dan dibangun menggunakan bahasa pemograman PHP (Personal Home Page) dan untuk perancangan basis data menggunakan Entity Relationship Diagram (ERD). Software yang digunakan adalah Xampp yang digunakan untuk webserver, PHPMySQL sebagai database, serta Adobe Dreamweaver CS6 sebagai editor PHP. Dengan adanya website ini maka akan membantu pengolahan data nilai para siswa yang di lakukan oleh guru agar lebih efisien.

Plants are living things that need water for growth, so plant growth affects the amount of water and nutrients that can be absorbed properly in the growth process. Plants obtain water through the soil which is absorbed by the roots, but plants with short roots such as mustard greens, tomatoes, chilies, and other vegetables find it difficult to reach deeper water. To maintain the quality of soil moisture in order to remain stable, special handling is needed, namely routine watering with attention to the percentage level of moisture in the range of 50% -70%. Currently, monitoring of plant watering is still done manually. This has several shortcomings, including requiring more manpower for monitoring, the higher the cost. Therefore, the authors conducted observations and experiments to provide solutions or problems, namely by designing an arduino-based soil moisture detector and automatic sprinkler, the results obtained from the design of the tool were: Soil Moisture Sensor which functions as an input successfully detects Soil moisture value (if the soil is dry) the water pump will automatically water it.Keywords - The Design, Automatic Springklers, Automatic Vegetable Watering, Arduino Uno.Abstrak: Tanaman merupakan mahluk hidup yang membutuhkan air untuk pertumbuhan, sehingga pertumbuhan tanaman berpengaruh pada jumlah air dan unsur hara yang dapat diserap secara baik dalam proses pertumbuhan. Tanaman memperoleh air melalui tanah yang diserap oleh akar, namun tanaman berakar pendek seperti sawi, tomat, cabai, dan sayuran yang lain sulit untuk menjangkau air lebih dalam. Untuk menjaga kualitas kelembaban tanah agar tetap stabil diperlukan penanganan khusus yaitu penyiraman rutin dengan memperhatikan tingkat persentase kadar air berkisar 50%-70%. Saat ini, monitoring penyiraman tanaman masih dilakukan secara manual. Hal ini memiliki beberapa kekurangan, diantaranya membutuhkan lebih banyak tenaga manusia untuk monitoring, biaya (cost) yang dikeluarkan semakin tinggi. Atas dasar itu itu penulis bermaksud melakukan pengamatan langsung dan eksperimen untuk memberikan solusi atau permasalahan tersebut yaitu dengan merancang alat pendeteksi kelembaban tanah dan penyiram otomatis berbasis arduino, dari hasil rancang bangun alat tersebut didapat hasil: Sensor Kelembaban Tanah (Soil Moisture Sensor) yang berfungsi sebagai input berhasil mendeteksi nilai kelembaban tanah (jika kondisi tanah kering) maka pompa air akan secara otomatis melakukan penyiraman.Kata kunci: Rancang Bangun, Alat Penyiram Otomatis, Penyiram Sayuran Otomatis, Arduino Uno

In the development of technology that is so advanced today, especially in the field of communication and information, maintaining privacy is something that absolutely must be done for each individual. Rapoport (in Soesilo, 1998) defines privacy as an ability to control the interaction, the ability to acquire options and the ability to achieve the desired interaction. Nowadays, a lot of things that can be done by using the internet, such as selling, social interacting through social media (Social Media) such as Facebook, learn, or just read the news through the portal of electronic media, and so forth. Most of the activities that can be done on the internet, requires personal data of its users, where the issue of privacy is of onsiderableconcern. As the development of information and communication technology in this case the Internet, the technology used to protect all personal data users also grown and will continue to evolve into more sophisticated. For this reason the author took the initiative to create a Endesapp application program, which aims to facilitate a person or agency who frequently exchange data in the form of files through the Internet. With so security in maintaining personal data even be increased as well as the possibility of the spread of sensitive data has been poor. In this study, the method used is to design programs shaped application file encryption and decryption web-based cryptographic techniques to the type of algorithm that is supported is 3DES ( Triple DES ) , AES - 128 ( Advanced encyption Standard) , AES - 192 and AES - 256.

The background of this research is to make a prototype of a Jakarta virtual tourism application system using Android OS and using virtual reality tools. The method used by this panel is to use a literature review and create an application prototype that will be applied to the making of a virtual Jakarta tourism program. The results of this study are the application of virtual reality tools on the Jakarta virtual tourism application which aims to help the tourism sector affected by the COVID-19 pandemic and the manufacture of application prototypes that use the Android OS. The limitation of this research lies in making an application prototype using the Android OS which is not perfect and has not produced a real application. This research is very useful for the development of the tourism sector during the COVID-19 pandemic and in the future, so that tourists can choose to travel online or offline.
