Abstract

Fluxgate is a magnetic sensor that capable to measure the magnetic field in a very small order. The basic principle of the fluxgate sensor is by comparing the measured magnetic field with the magnetic field reference. In this paper, we describe the characterization of fluxgate magnetic sensor using the double secondary coil design. Configuration of primary coil winding and secondary coil that be used is 4x40 and 2x60. We use vitrovacs 6025Z (1.5 mm width and 0.025 mm thick) as the sensor core. Sensor characterization with varying amounts of the core layer is made to determine the influence of the core layer to the demagnetization factor and the sensor sensitivity. The demagnetization factor is performed by measuring the dimensions of the sensor element and the inductance of the sensor. The inductance of the sensor is measured using a LCR meter GW Instek 829 series at a frequency of 10 kHz. The calculation results show that the increasing amounts of the vitrovac core layer is proportional to the demagnetization factor. To determine the sensor sensitivity, sensor calibration is performed by giving the external field on the calibration coil in a faraday chamber. From the sensor calibration we get the relationship between the external fields with the sensor output voltage. Based on this relationship, we can calculate the sensor sensitivity in working range ± 4 μT. Sensor sensitivity is inversely proportional to the amounts of vitrovac core layer. Sensor with 2 vitrovac core layers has the highest sensitivity (641 mV / μT), and has the smallest absolute error (0.1 at the point of 3.87 μT). Keywords: fluxgate, external field, vitrovac, sensitivity, demagnetization factor, inductance.

Abstract

Dewasa ini ketersediaan air bersih semakin menurun, tidak sebanding dengan kebutuhan air bersih yang kian meningkat. Banyaknya penduduk dan peningkatan industri mengakibatkan produksi limbah cair semakin banyak. Kualitas air yang baik ditentukan berdasarkan beberapa parameter fisis antara lain suhu, kekeruhan, warna, daya hantar listrik, jumlah zat padat terlarut, salinitas, indeks bias, tegangan permukaan, pH dan viskositas. Viskositas merupakan indikator yang penting dalam menentukan kualitas air tercemar, namun alat ukur viskositas sangat terbatas. Oleh karena itu diperlukan pembuatan alat ukur viskositas yang efektif, efisien dan presisi. Pada penelitian ini telah dikembangkan alat ukur viskositas zat cair yang memanfaatkan sensor optik tipe through beam berbasis Arduino Uno R3. Dari hasil karakterisasi sensor viskositas menggunakan viskometer Ostwald diperoleh sensitivitas sensor sebesar 17.31 mV/cP dengan kesalahan relatif maksimum 4.605%. Hasil pengukuran sampel air sungai ( Banjir Kanal Timur (BKT), Bekasi, Cipinang dan Galur ) diperoleh nilai viskositas berturut-turut 1.246 cP, 1.268 cP, 1.248 cP dan 1.546 cP. Hasil pengukuran sampel air sungai menunjukkan bahwa nilai viskositas air sungai tersebut melebihi batas normal air bersih yaitu 1.002 cP pada suhu 200C, sehingga air sungai di atas dapat dikatakan tercemar. Today, the availability of clean water is decreasing, not worth the need for a growing water. Many population and industry improvement resulted in more liquid waste production. Good water quality is determined based on several parameters phisycs among others temperature, turbidity, color, electrical power, the amount of dissolved solids, salinity, refractive index, surface tension, pH and viscosity. Viscosity is an important indicator in determining the quality of polluted water, but the viscosity measuring instrument is very limited. It is therefore necessary to manufacture effective, efficient and precise viscosity measuring instruments. In this study, a liquid measuring instrument has been developed that utilizes the Arduino Uno R3-based through beam type optical sensor. From the results of characterization of viscosity sensors using the Ostwald viscometer obtained sensor sensitivity of 17.31 mV/cP with a maximum relative error of 4,605%. The results of river water sampling (East Canal Flood (BKT), Bekasi, Cipinang and Galur) were obtained in successive viscosity values of 1,246 cP, 1,268 cP, 1,248 cP and 1,546 cP. The results of the river water sample measurement showed that the viscosity of the river water value exceeded the normal clean water limit of 1,002 cP at 200C, so the river water above can be said to be polluted.

Abstract

Seiring dengan pertambahan penduduk dan pembangunan ekonomi, jenis dan kuantitas limbah cair semakin besar. Di lain pihak kebutuhan air bersih juga semakin meningkat. Hal ini tidak diimbangi dengan kondisi kualitas air yang semakin menurun. Salah satu syarat air yang dapat dimanfaatkan untuk kebutuhan air bersih adalah air yang memiliki nilai salinitas ≤0.5 ppt. Salinitas menggambarkan kadar garam yang terlarut dalam air. Pada penelitian ini dirancang pengukuran salinitas air tercemar limbah cair menggunakan sensor konduktivitas dan Arduino UNO sebagai sistem kontrol. Penelitian ini bertujuan untuk mengetahui apakah air sungai yang diuji layak dijadikan sumber air bersih berdasarkan parameter salinitas. Hasil karakterisasi sensor menunjukkan sensitivitas sensor sebesar 0.4152 mV/ppt dengan kesalahan relatif maksimum sebesar 5.26%. Pada pengujian salinitas air sungai, diambil sampel yang berasal dari wilayah Cipinang, Banjir Kanal Timur (BKT), Galur, dan Bekasi. Berdasarkan hasil pengujian salinitas, sampel air sungai yang diambil dari keempat wilayah yang berbeda memenuhi syarat salinitas air bersih yaitu ≤0.5 ppt sehingga layak dijadikan sumber air bersih. Along with population growth and economic development, the type and quantity of liquid waste is getting bigger. On the other hand, the need for clean water is also increasing. This is not balanced with the condition of declining water quality. One of the requirements for water that can be used for clean water needs is water that has a salinity value of ≤0.5 ppt. Salinity describes the salt content dissolved in water. In this study, the measurement of salinity of polluted water using a conductivity sensor and Arduino UNO as a control system was designed. This study aims to determine whether river water tested is suitable as a source of clean water based on salinity parameters. The sensor characterization results showed sensor sensitivity of 0.4152 mV / ppt with a maximum relative error of 5.26%. In testing the river water salinity, samples were taken from the Cipinang area, Banjir Kanal Timur (BKT), Galur, and Bekasi. Based on the results of salinity testing, river water samples taken from the four different regions meet the salinity requirements of clean water, namely ≤0.5 ppt so that they are suitable as a source of clean water.

Abstract

Gelombang bunyi merupakan salah satu materi sulit pada UN SMA. Terbukti dari turunnya persentase daya serap siswa dalam kurun waktu empat tahun terakhir, dengan rata-rata penurunan sebesar 15.3%. Salah satu penyebabnya adalah media pembelajaran yang berkaitan dengan materi pelayang bunyi dan efek doppler masih sangat minim. Hasil dari analisis kebutuhan menunjukkan bahwa proses pembelajaran fisika di sekolah 39% didominasi oleh pemberian tugas dan latihan soal. Namun, hanya 9% saja pembelajaran fisika di sekolah dilakukan dengan kegiatan praktikum. Kegiatan praktikum pada materi pelayangan bunyi dan efek doppler yang dilakukan guru di sekolah kebanyakan masih menggunakan alat seadanya, dan hasil yang didapat merupakan data secara kualitatif. Sehingga pada penelitian ini dikembangkan alat praktikum pelayangan bunyi dan efek doppler dengan menggunakan mikrokontroler Arduino uno sebagai sistem kontrol, modul mikrofon kondenser sebagai penangkap sumber frekuensi, dan motor dc sebagai penggerak sumber frekuensi. Dari hasil pengujian, alat praktikum pelayangan bunyi dan efek doppler ini dapat bekerja dengan baik. Sound waves is one of the difficult material on senior high school national examination. As evidenced by the decline in the percentage of absorption of students in the past four years, with an average decline of 15.3%. One of the causes is learning media related to material beats and doppler effects are still very minimal. The results of the needs analysis show that the learning process of physics in schools is 39% dominated by assignments and exercises. However, only 9% of physics learning in schools is done by practical activities. Practical activities on material beats and doppler effects conducted by teachers in most schools still using a simple tools, and the results obtained are qualitative data. This research aims to develop practicum tool on material beats and doppler effects by using microcontroler Arduino uno as a system control, microphone condenser module as frequency source catcher, and motor dc as a frequency source driver. From the result of the test, the practicum tool of beats and doppler effects can work well.
