Search is the process of finding solutions in a problem until a solution or goal is found, or a movement in the state-space to search for trajectories from initial-state to goal-state. In a TIC TAC Toe game the process of finding a space situation is not enough to automate problem-solving behavior, in each of these situations there are only a limited number of choices that a player can make. The problems that will be faced can be solved by searching from the choices available, supported by the usual way of resolving. Best First Search works by searching for a directed graph which each node represents a point in a problem space.

Online book stall is one form of e-commerce in cyberspace, all the time the sale and purchase transactions of books can be done at any time, but along with the development of online transactions, data controls should also be improved. To avoid data from damage caused by irresponsible people, it is necessary to secure data by applying cryptography to the data. In modern times there are many methods or algorithms that can be used to protect and control data from various attacks, but each of these algorithms certainly has its own weaknesses and strengths. The need for long-distance transactions and the importance of data security caused developers to continue to develop cryptography. MD5 algorithm is a one-way hash function that is often used in cryptography, especially in web-based transactions. The MD5 algorithm encodes data in a constant form of 32 bits. All processes from sales and purchase transactions in online bookstores will be safe and durable when the bookstore database is designed in such a way. The book stall database records are encoded with the MD5 algorithm, especially for logging records as a gateway for hackers or hackers to infiltrate. All transactions in the online book kiosk system are detected by the database, the resilience of the database from all attacks is the control of the system from all kinds of damage.

The source of science is still dominated by books, although with the internet students get information with diverse scientific fields, but actually the information comes from material in the book. To be able to master a material from a book, students must first be able to read and understand well. Nowadays software is growing very rapidly. The world of education has also used software to create interactive learning application methods with multimedia concepts. This can help overcome, the level of difficulty experienced by students, in order to be able to attract student learning interest, so that it can automatically improve the learning process to be more active and effective. Actually this method has been widely used and has good benefits in learning. As for the achievements of this study to assist students in learning and understanding the learning of data security techniques, this is a solution in several learning problems, namely an explanation that is too fast, a conducive atmosphere, time, learning media and student interest.

Topography and geographical conditions in Indonesia are very supportive in the effort to use solar energy as a producer of electrical energy. In this research, Dye Sensitized Solar Cell (DSSC) was fabricated using the doctor blading deposition method for coating TiO2 onto the substrate. The research focused on the effect of varying TiO2 thickness. TiO2 as an electron jumping pathway and binders for dye molecules, dye to absorb photons which will help generate electricity. the iodide / triiodide redox pair as electrolyte, and carbon as the counter electrode on the DSSC. TiO2, organic dyes, electrolytes, and counter electrodes are arranged and combined with a layered structure as a donor-acceptor layer. In testing the output power measurement using the Internet of Things, where testing cells at a thickness of 292 micrometers using a 7 watt LED lamp produces the maximum power reaches 4429.8 x 10-9 W.

A lot of data is misused without the data owner being aware of it. Software developers must ensure the security user data on their system. Due to the size of the market that houses data, the security of record databases must be of great concern. Cryptographic systems or data encryption can be used for data security. The Merkle-Hellman Knapsack algorithm is included in public-key cryptography because it uses different keys for the encryption and decryption processes. This algorithm belongs to the NP-complete algorithm which cannot be solved in polynomial order time. This algorithm has stages of key generation, encryption, and decryption. The results of this study secure database records from theft by storing records in the form of ciphertext/password. Ciphertext generated by algorithmic encryption has a larger size than plaintext.

Indonesia merupakan negara kepulauan yang secara geografis berada pada jalur khatulistiwa dengan morfologi yang beraneka ragam dari daratan sampai perguruan tinggi. Kekayaan alam Indonesia dengan luas wilayahnya, merupakan sumber yang harus dijaga kelestariannya. Hanya saja terkadang semakin berkembangnya negara Indoesia, semakin banyak dibuat pembangunan, perubahan dan sebagainya sehingga manusia sendiri sering menanggung akibatnya, salah satunya bencana.Penggunaan Teknologi dalam mendeteksi suatu objek sangat popular pada saat ini mulai dari kebutuhan dalam mendeteksi objek seperti wajah, sidik jari dan sejenisnya menjadi awal dalam pengembangan aplikasi olah citra digital yang lebih efisien dan modern. Dalam kajian ini membahas tentang bagaimana sebuah Drone (DSAR) yang dilengkapi dengan teknologi identifikasi objek dengan menggunakan sebuah algoritma SIFT pada citra digital dalam membantu petugas Tim SAR (Search and Rescue) mengidentifikasi objek dan gambar melalui sebuah Drone pada sebuah area yang mengalami suatu bencana atau kecelakaan, yang kemudian dikirimkan ke Komputer untuk diproses. Dengan ini Tim akan mudah dalam melakukan Pemetaan Objek dan dapat mengkordinatkan lokasi yang akan di Cari dan di Evakuasi.
