Perkembangan sistem informasi seiring dengan kemajuan teknologi informasi yang signifikan, berperan dalam penyimpanan, pengelolaan, dan pendistribusian informasi. Salah satu contohnya adalah dalam pengelolaan data instalasi kabel serat optik. Dinas Komunikasi dan Informatika Bangkalan, sebagai instansi pemerintah, menghadapi tantangan dalam pencatatan data serat optik yang masih dilakukan secara konvensional menggunakan perangkat lunak Excel. Untuk mengatasi masalah ini, peneliti merancang dan mengembangkan "Sistem Informasi Instalasi Kabel Serat Optik di Kabupaten Bangkalan." Tujuan dari sistem ini adalah untuk meningkatkan efisiensi dan efektivitas dalam pengelolaan data, menyederhanakan proses pencatatan, dan mempercepat akses informasi kepada pihak terkait. Hasil pengelolaan data dalam sistem informasi ini mencakup empat proses utama: pengelolaan data titik instalasi, pengelolaan data lokasi, pengelolaan data pengguna, dan pengelolaan data kecepatan internet. Penerapan metode waterfall dalam perancangan sistem informasi ini memberikan solusi untuk meningkatkan efisiensi dan efektivitas dalam pengelolaan data. Perancangan sistem informasi ini terdiri dari lima (5) perancangan utama yaitu: 1) Menampilkan halaman pengunjung ketika aplikasi diakses, 2) Menerima dan mengolah data berdasarkan tindakan CRUD (create, read, update, delete), 3) Melakukan verifikasi data login dan menampilkan pesan error apabila data login salah, 4) Menyediakan fitur pencarian data, dan 5) Menghasilkan laporan data instalasi.

This research aims to analyze the scheduling of the fiber optic network construction project in Lemo-Lemo, Bulukumba, using the Critical Path Method (CPM). This method was chosen to improve time and cost efficiency in project implementation. Research data were obtained through field observations, literature studies, and interviews with related parties. Analysis was carried out by mapping project activities, estimating duration, and calculating resource requirements and project costs. The results showed that the application of the CPM method was able to accelerate project completion from the initial estimate of 40 days to 21 days, with time savings of 19 days. In addition, the project cost which was initially estimated at Rp. 38,386,680 was successfully reduced to Rp. 37,000,000, resulting in a savings of Rp. 1,386,680. In conclusion, the CPM method proved to be effective in improving time and cost efficiency in fiber optic network construction projects. Therefore, it is recommended that this method be applied consistently in similar projects in the future.

The development of information and communication technology is increasing rapidly from year to year, especially in the field of telecommunications. Communication technology via fiber optic is one of the technologies that is widely used as a data sender, between senders and receivers in one network, users can communicate with each other at very high speeds. This is in line with the community's need for fast communication services. FTTH (Fiber To The Home) is a telecommunications service infrastructure that supports transmission on large bandwidths and can solve bandwidth access problems so that PT. Telkom designs fiber to the home network access using GPON technology by determining its usage.    

Pelengkungan yang terjadi pada sebuah kabel serat optik sangat berpotensi menimbulkan rugi daya yang cukup serius dan lebih jauh lagi menyebabkan pecahnya serat optik. Oleh karena itu perlu dilakukan pengukuran pengaruh pelengkungan serat optik terhadap rugi daya yang dihasilkan ketika serat optik dilengkungkan.Penelitian ini bertujuan untuk mengetahui perubahan intensitas cahaya keluaran yang melalui  serat optik plastik. Skripsi ini hanya membahas mengenai perhitungan keluaran cahaya yang telah dipengaruhi oleh lekukan pada serat optik.Dari analisa yang dilakukan dengan panjang kabel fiber optik 100 m, redaman sebesar 0,2 dB/km dan radius pelengkungan yang bervariasi dengan radius pelengkungan sebesar 15 cm, 10 cm, 7 cm, 5 cm dan 2,25 cm, maka diperoleh rugi-rugi pelengkungan serat optik berturut -0,366 db, -0,312, -0,689, -0,914 , -1,658.

The use of Fiber Optic as a light emitter in Cocktail Dress is expected to be a new innovation in the development of party fashion. The objectives of this study are: 1) To explain the process of making a cocktail dress using Fiber Optic as a light emitter. The method used in this research is the Research and Development (R & D) method. The R&D method is a research method that tests a product to produce the best product by conducting direct trials. In addition to using the method (R&D), it also uses the method of literature, documentation, and experiments. The experiment of making Cocktail Dress using Fiber Optic as a light emitter was carried out at the Laboratory of the Fashion Design Study Program of the Kartini Academy of Social Welfare, st. Sultan Agung, No. 77 Gajah Mungkur Village, Semarang City. The percentage of additional ingredients in making Cocktail Dress, namely: 3 meters Bridal Satin Fabric, 1meter Furing, 2 meters Trikod, 1 seed thread, zipper size 50 cm 1 item, zippers size 25 cm 1 item, Fiber Optic in amount of 0.75 mm-400 m. The results of this study indicate that the Fiber Optic Cocktail Dress has the characteristic that the resulted cocktail dress can shine with the light emitting from the Fiber Optic. Thus, it can be concluded that there is an opportunity for innovation from Cocktail Dress by adding Fiber Optic.
