Abstract

Peralatan laboratorium perlu dilakukan pendataan secara digital agar jumlah dan kondisinya dapat diperbarui dengan cepat. Dengan membuat perangkat lunak inventaris alat dan bahan, dapat digunakan petugas laboratorium sebagai sistem informasi ketersediaan alat dan bahan dalam melayani dosen dan mahasiswa pada saat melakukan praktikum maupun penelitian. Perancangan perangkat lunak dibuat sesuai masukan dari petugas laboratorium. Metode yang di gunakan dalam perancangan software adalah manajemen basis data. Semua alat dan bahan yang dilakukan pendataan dilakukan pemberian kode unik yang kemudian disimpan dalam database. Kode unik digunakan untuk mempermudah pencarian alat dan bahan ketika laboran melakukan pelayanan kepada dosen maupun mahasiswa. Hasil dari perancangan perangkat lunak kemudian dilakukan implementasi dan pengujian sistem untuk mengetahui. Pengujian fungsional perangktat lunak yang selesai dibuat kemudian di tes menggunakan metode blackbox testing. Hasil dari pengujian menunjukkan bahwa software yang dirancang sudah sesuai dengan kebutuhan operator dalam melakukan inventarisasi alat dan bahan yang ada di laboratorium.

Abstract

A study was conducted to identify heavy metals iron or Ferrum (Fe), Cadmium (Cd), and copper or Cuprum (Cu) based on the depth of well water using atomic absorption spectrophotometry method, pH test of water by measuring using digital pH meter and water turbidity using Turbidity meter with NTU (Nephelometric Turbidity Unit) unit in Lamakera Village, East Flores Regency. The purpose of this study was to determine the content of heavy metal elements, pH content and turbidity of the well water. The results showed that the analysis of heavy metal content in well water had the same levels in wells A (10 m), B (25 m), and C (15 m). The levels are Fe < 0.03 mg/L, Cd < 0.0007 mg/L, and Cu < 0.010 mg/L as well as the average pH content in well A on the surface is 6.99 and the base is 6.63. Well B on the surface is 6.34 and the base is 6.29. Well C surface 6.45 and base 6.56. The turbidity of well A at the surface is 0.93 NTU and the bottom is 0.66 NTU. Well B at surface 0.6 NTU and bottom 0.86 NTU. Well C at surface 0.8 NTU and bottom 0.86 NTU.

Abstract

Testing of oil viscosity sensor based on plastic optical fiber by using bending angle variation method to enhance the sensor sensitivity. This sensor is made by forming an optical fiber bending angle, it is dipped into the oil viscosity liquid. The light transmitted through into the optical fiber will be received by the photodetector and the measurement results are displayed on the OPM in the form of output power. The best measurement obtained at the bending angle of 300 with value of sensor sensitivity is 1.013 nW/mPa.s. This method has the advantage of high sensitivity in a simple measurement process.
