Penelitian ini mengeksplorasi penerapan teknologi Progressive Web Application (PWA) pada website Jahitku dengan memanfaatkan framework Laravel. Fokus utama dari penelitian ini adalah untuk menciptakan pengalaman pengguna yang lebih responsif dan cepat, mirip dengan aplikasi mobile, serta memastikan aksesibilitas dalam kondisi offline. Melalui survei yang melibatkan 17 pengguna, ditemukan bahwa kebutuhan akan akses yang stabil dan cepat menjadi prioritas utama. Metodologi yang digunakan mencakup pengumpulan data melalui studi literatur dan pengujian performa menggunakan alat seperti Lighthouse dan GTMetrix. Hasil penelitian menunjukkan bahwa implementasi PWA pada website Jahitku tidak hanya memenuhi semua kriteria PWA, tetapi juga menghasilkan peningkatan signifikan dalam performa, dengan skor Lighthouse meningkat dari 44% menjadi 99% dan GTMetrix dari 61% menjadi 97%. Penelitian ini menegaskan pentingnya adopsi teknologi PWA dalam meningkatkan kinerja website dan memberikan nilai tambah bagi pengguna, serta membuka peluang untuk penelitian lebih lanjut dalam pengembangan aplikasi berbasis web.

The purpose of this research is to design over the air programming mechanism for a node in wireless sensor network. Data are gathered from experiments of the proposed system on a constrainted environment. On this design, the Arduino that becomes the target of reprogramming has it’s bootloader modified to enable the capability to run embedded program from the SD Card. Arduino’s source code .ino file is compiled into a .hex file using the Arduino IDE. Then, it is processed using avrdude application into a ready to run firmware binary file on Arduino. A desktop application is made for this mechanism in order to control sender XBee device in transmitting data packet by packet. If the transmission was successful, the node will restart itself, and trigger the bootloader to load new program from the SD Card. The system is evaluated through preset scenarios which including testing at various distances and environments (indoor and outdoor). It was concluded that the reprogramming mechanism was uneffective in transmitting source code when at least one of the XBee devices is located inside the building which affected the transmission process. For the second testing scenario, both nodes were located outdoors with testing distance up to 15 metres, resulting with average transmission speed of 35 bytes per second for sent packet size of 60 bytes. The safest sent packet size to avoid packet loss while transmitting should not exceed 30 bytes for transmission distance up to 15 metres. Transmission speed across all test scenarios ranges between 14 bytes per second to 35 bytes per second. For indoor testing, the evaluation results showed that the designed OTAP mechanism in this study is not yet effective. This is assumed to be influenced by the transmission capability of the XBee communication module.

The Final Project guidance process often faces obstacles such as inflexible schedules, limited space and time, and difficulties in communication between supervisors and students directly. This study aims to implement a web-based Final Project guidance system using the Laravel framework designed using the Waterfall method and the PHP programming language and MySQL as a database. Data in this study were obtained through observation, literature studies and interviews. Testing in this study was carried out using the Black Box method and User Acceptance Testing (UAT). The results showed that this application was feasible for use by students and lecturers with an average test score on the Usability aspect of 86.68%, on the Information Quality aspect of 84.88%, and on the Service Interaction Quality aspect of 83.86%. Based on the feasibility category interval of 81% - 100%, this system was declared very feasible for use, in addition this system was able to overcome traditional obstacles in the Final Project guidance process.
