The library strives to maintain and improve efficiency and effectiveness in teaching and learning. Currently there are still many library services that use manual methods. Computerized service systems are able to streamline library services, so transactions such as searching, borrowing, returning and managing data can be done quickly and accurately. In this research, a website-based library service system is integrated with Radio Frequency Identification (RFID) as a library visitor identity card which can also be used when borrowing and returning books, and Quick Response Code (QR Code) is used as book identification. In this application the admin can process data, register books and members, borrow and return books, and view transaction reports. This application also provides e-mail notifications to resolve problems such as late returns to the loss of borrowed books. The notification automatically sends a message to the user to return the book on the last day of the loan. The existence of a service system in this website-based library application makes it easier for administrators in managing data, improving library services, and email notifications helps to remind the day of returning books.

The main cause of the decline in the existence of air Cihampelas service is so expensive. So many people are switching using Cihampelas land as Travel between cities for example, as alternative means. This transport is rated more pocket friendly, because the cost offered is more affordable. But the community is still very minimal in the Kokoro which is about the availability of a successful trip. This is due to the provision of tickets that are still conventional. Therefore, by utilizing technology officials in the current communication, the author is interested to create a travel reservation system application that can run in a smartphone. This app will only be devoted to Android-based smartphones. The creation of this app uses Android Studio with Java as its main programming language. The application also uses the PHP Framework and MySQL databases with servers that are online. With this application, prospective Jeti can Kokoro about accurate travel related from the time, route, village TARIFF i.e. make a reservation and payment can be made in a grip anytime and anywhere.

Solar energy is now a very important means of renewable energy resources. With sun tracking, it is more effective to produce more energy because solar panels can maintain a profile perpendicular to sunlight. Although the initial cost of setting up a tracking system is quite high, there are cheaper options that have been proposed from time to time. Light Dependent Resistors (LDRs) are used to detect sunlight. The solar panel is positioned where it can receive maximum light. Compared to other motors, servo motors are able to maintain torque at high speed. The tracker is in the form of a double or single axis. Dual trackers are more efficient because they track sunlight from both axes. This project is designed for low power and portable applications. Therefore, it is suitable for use in rural areas. In addition, the effectiveness of the output power collected by sunlight increases.

Air Conditioner (AC) perangkat elektronik yang dapat mengatur suhu suatu ruangan. Kondisi suhu ruangan sangat mempengaruhi kenyamanan pengguna dalam melakukan kegiatan sehari-hari. Namun AC menjadi salah satu beban yang mengkonsumsi banyak energi listrik. Sering kali pengguna lupa mematikan AC saat hendak meninggalkan ruangan. Maka dari itu diperlukan suatu sistem pemantau suhu ruangan dan pengendali pendingin ruangan jarak jauh.Solusi untuk menangani masalah ini yaitu dibuatlah sebuah sistem dengan menggunakan teknologi internet yang disebut dengan Internet of Things (IoT) yang dapat memantau keadaan suhu dan AC dalam waktu nyata. Untuk dapat merealisasikan sistem ini dibutuhkan sebuah protokol untuk mengimplementasikan IoT yaitu Message Queuing Telemetry Transport (MQTT). Sistem ini dibuat menggunakan Raspberry Pi sebagai server, sensor DHT22 sebagai sensor suhu dan Infrared LED sebagai pengirim sinyal ke AC.Hasil akhir dari penelitian ini yaitu hasil bacaan sensor suhu dan fitur pengendali AC ditampilkan pada aplikasi pemonitoring dan dapat dipantau dan dikendalikan jarak jauh. Data hasil pembacaan suhu disimpan pada database.

Television is one of the most widely used media for receiving sound and image transmissions worldwide, particularly in Indonesia. Government regulations require all television broadcasters in Indonesia to cease analog broadcasts and transition to digital broadcasts. Consequently, a device known as the Set Top Box (STB), equipped with a low noise amplifier (LNA), converts DVB-T2 digital signals into images and audio suitable for analog televisions. Tests were conducted to evaluate its signal reception capabilities. These tests took place at four Palembang city locations, utilizing indoor and outdoor antennas. The results revealed that the device's signal strength ranged from -48.7 dBm, reaching 100% signal quality, to the weakest signal at -97 dBm. Moreover, an average difference of 6.9 dB was observed between indoor and outdoor testing for each frequency. Furthermore, analyzing the average signal strength based on distance showed that the highest strength of -56.2 dBm occurred at a distance of 1.5 km from the transmitter during outdoor testing. In comparison, the weakest strength of -91.6 dBm occurred at a distance of 1.8 km during indoor testing. Additionally, a signal strength comparison between test locations indicated that the most significant difference was between the Kamboja and Plaju locations. The LNA device achieved its highest gain value of 15.2 dB. Various factors, including antenna direction, obstructions such as buildings, antenna height, signal stability, and the distance between the transmitter and receiver, influence the signal quality.
