Abstract

Running text or commonly known as text running a medium to deliver information that is most often encountered as a means of advertising that are informative. Running text display is generally in the form of LED-LED are connected and assembled into a row of LED or may be a dot matrix. Submission of information by displaying the running text has not been effective and efficient in terms of use. There are still shortcomings that enable people to experience vision errors and too long waiting for the text to be displayed. Thus the necessary tools to deliver information that can work optimally to minimize shortages by designing a control tool running text using voice (voice) and arduino uno. This tool uses a series of android smartphones facilities to provide input sound is converted into a data string and compiled in arduino using serial communications, and will be displayed on the LED Dotmatrix as output. Submission of information by using running text that comes with using sound can improve efficiency and effectiveness in the use and also the time required so that it can reduce the level of difficulty of the user in receiving the information

Abstract

Tiga hal utama yang harus terpenuhi dalam pelaksanaan proyek, yaitu tepat waktu, biaya dan mutu. Terkadang dalam pelaksanaannya di lapangan ada beberapa pekerjaan yang hasil dari penyelesaiannya tidak sesuai dengan rencana yang sudah ditentukan. Diperlukan  upaya pengendalian efektif tentang manajemen pelaksanaan pada proyek. Pengendalian efektif yang dimaksud adalah tugas manajer proyek memanfaatkan kemajuan teknologi dan metode-metode tentang  optimalisasi biaya dan waktu proyek tanpa mengurangi mutu proyek. Proyek pembangunan Rusun 1 Kota Samarinda Kalimantan Timur dipilih untuk studi kasus karena pada  pengendalian proyek ini menggunakan kurva S yang hanya terfokus di dalam bobot dan durasi pekerjaan. Sehingga  proyek tersebut dapat ditingkatkan dalam memantau dan mengendalikan proyek menggunakan metode optimalisasi biaya dan waktu. Penelitian ini menggunakan metode  Time Cost Trade Off (TCTO), proses ini dimulai dengan mencari lintasan kritis melalui program Microsoft Project 2016, percepatan dilakukan untuk mendapatkan cost lope dan total cost, kemudian metode Least Cost Analysis digunakan untuk mendapatkan perubahan biaya dari penambahan  jam kerja. Data yang diperlukan adalah RAB, daftar analisa harga satuan pekerjaan, jadwal waktu pelaksanaan. Percepatan  dilakukan dengan melakukan penambahan  jam kerja (waktu lembur) dari jam kerja normal.   Berdasarkan data serta hasil analisis dan pembahasan yang dilakukan  jumlah kegiatan kritis yang diperoleh adalah 7 kegiatan dari 14 kegiatan proyek dengan durasi normal proyek adalah 434 hari. Durasi yang diperoleh setelah dilakukan percepatan dengan metode Time Cost Trade Off yaitu 422 hari dengan waktu percepatan sebesar  12  hari atau  efisiensi waktu proyek sebesar  0.25  %.  Biaya optimal yang diperoleh  setelah melakukan percepatan dengan penambahan  jam  kerja yaitu  sebesar  Rp 35.314.459.000,00 dari total biaya normal sebesar Rp 34.529.890.000,0.

Abstract

In the industrial world, employee safety and comfort are crucial aspects that cannot be ignored. One factor that significantly affects these aspects is adequate workplace lighting. This study aims to evaluate the impact of light intensity and eye complaint factors on worker safety and comfort and provide recommendations for companies with lighting that does not meet the standards of the Indonesian Minister of Health Regulation No.70 of 2016. The research method involves regression analysis and data collection through observation in the form of questionnaires and light measurement data, processed quantitatively, conducted at PT. X. Questionnaire results analyzed with linear regression testing indicate that light intensity in the shortening packaging and control rooms at PT. X negatively impacts employee safety and comfort, with a total effect of 80.8%. Based on direct measurements using a light intensity measurement tool (lux meter), the light intensity conditions in the shortening packaging and control rooms range from 103–267 lux. This intensity level does not meet the standard of 300 lux for production rooms, as stated in the Indonesian Minister of Health Regulation No.70 of 2016. Thus, the company needs to control light intensity to prevent accidents and discomfort among employees caused by inadequate lighting conditions
