Abstract

AbstrakPerovskite manganit merupakan salah satu rekayasa material yang dapat menghasilkan perubahan fenomena fisika. Telah berhasil dibuat material berbasis perovskite manganit Nd0,6Sr0,4MnO3 menggunakan metode sol-gel¬ dan dikompositkan dengan ZnO (Nd0,6Sr0,4MnO3)1-x/(ZnO)x (x = 0; 0,3; 0,5; 0,7). Hasil pengujian X-Ray Diffraction menunjukkan sampel Nd0,6Sr0,4MnO3 berstruktur tunggal ortorombik dan sampel ZnO pada (Nd0,6Sr0,4MnO3)0,5/(ZnO)0,5 berstruktur heksagonal tunggal. Hasil pengujian Field Emission Scanning Electron Microscope menunjukkan sampel telah homogen dengan rata-rata ukuran butir 0,188 μm. Hasil pengujian Vibrating Sample Magnetometer menunjukkan sampel (Nd0,6Sr0,4MnO3)0,5/(ZnO)0,5 bersifat paramagnetik dan mengalami penurunan sifat magnetik juga suseptibilitas seiring dengan penambahan konsentrasi material ZnO. AbstractPerovskite manganite is one of the manipulation materials that can produce changes in physical phenomena. Perovskite material Nd0,6Sr0,4MnO3 has been made with the sol-gel method and then composites with ZnO (Nd0.6Sr0.4MnO3)1-x/(ZnO)x (x = 0; 0.3; 0.5, 0, 7). The results of the X-Ray Diffraction characterization test showed samples of Nd0,6Sr0,4MnO3 and ZnO each with a single orthorhombic phase with a Pnma space group and a single hexagonal with a P63mc space group. The results of the Field Emission Scanning Electron Microscope characterization test showed that the samples were homogeneous with an average grain size of 0,188 μm. Vibrating Sample Magnetometer characterization test results show composite material (Nd0,6Sr0,4MnO3)1-x/(ZnO)x are paramagnetic and the increasing composition of ZnO material decreases the magnetization and susceptibility value of sample

Abstract

Abstrak.Penelitian tentang struktur kristal  bahan La0.7(Ba1-xSrx)MnO3  menggunakan metode sol-gel telah berhasil dilakukan. Bahan-bahan dasar yang digunakan dicampur di atas hot plate diaduk sambil ditetesi ammonia solution sehingga mencapai pH 7, selanjutnya didiamkan sampai diperoleh bentuk gel. Gel dikeringkan pada suhu 120°C, selanjutnya dilakukan pra-kalsinasi dengan suhu 650°C selama 6 jam, dilanjutkan dengan kalsinasi  pada suhu 1000°C selama 12 jam, dan kemudian disinter pada temperatur 1200°C selama 12 jam. Hasil refinement data  XRD memberikan informasi bahwa struktur kristal  La0.7(Ba1-xSrx)MnO3 adalah rombohedral dengan space grup R-3c. Penambahan substitusi ion Sr2+ mengakibatkan terjadinya penurunan intensitas dan pergeseran puncak ke arah sudut yang lebih besar. Hal ini disebabkan karena pengaruh jari-jari ion Sr2+ yang lebih kecil dibandingkan dengan jari-jari ion Ba2+ . Abstract.In this research,  La0.7(Ba1-xSrx)0.3MnO3  compound (x = 0; 0.2; 0.3; and 0.5) by sol-gel method has been investigated.  The compound used is mixed on a hot plate until reached a pH 7 when dropped ammonia solution, then let stand until turn into a gel. Dehydrated gel at 120°C, pra-calcination at 650°C for 6 hours, calcination t 1000°C for 12 hours, and sintering at 1200°C for 12 hours. The result of refinement XRD pattern shown that samples are single phase with rhombohedral crystal structure with R-3c space group. The intensity decrease and peak list shift to larger angle when Sr-substitution increased, it’s caused  ionic radii of Sr2+ is smaller than Ba2+ .

Abstract

Abstrak. Secara geografis Pulau Jawa berhadapan langsung dengan zona tumbukan lempeng Eurasia dan Indo-Australia yang menyebabkan wilayah tersebut rawan terjadinya gempa bumi, salah satunya gempa tersebut yaitu di Lebak, Banten dengan magnitudo 6,1. Maka diperlukan usaha untuk meminimalisir resiko gempa bumi, seperti pengamatan prediksi jangka pendek melalui fenomena medan magnetik bumi. Tujuan dari penelitian ini adalah untuk menganalisis apakah terdapat anomali sinyal geomagnetic Ultra Low Frequency (ULF) sebelum gempa bumi terjadi. Penelitian ini menggunakan data geomagnetik periode Januari hingga Februari 2018 di Lebak, Banten dengan metode yang digunakan adalah Detrended Fluctuation Analysis (DFA). Pengamatan yang dilakukan pada penelitian ini merupakan penelitian lanjutan berdasarkan penelitian terdahulu yang dilakukan dengan metode spectral density ratio. Berdasarkan pengolahan data diperoleh nilai α pada masing-masing komponen, untuk komponen H memperoleh nilai α= 1.99, komponen D dan Z memperoleh nilai α = 1.2 hingga 1.6. Berdasarkan analisis dari ketiga komponen tersebut, menunjukkan terjadinya penurunan nilai α yang disajikan oleh panel komponen D dan Z. Pada saat yang sama, hasil spectral density ratio mengalami kenaikan nilai rasio Z/D. Nilai dari indeks DST (Disturbance Strom Time) menunjukkan tidak terjadi aktivitas badai geomagnet global sebelum dan sesaat terjadinya gempa bumi M = 6,1. Dengan hasil yang diperoleh ini menunjukkan terdapat adanya kemunculan anomali sinyal geomagnetic Ultra Low Frequency (ULF) pada 7 dan 11 hari sebelum gempa bumi bermagnitudo 6,1. Abstract. Geographically, Java Island is dealing directly with the Eurasian and Indo-Australian plate collision zones which cause the area to be prone to earthquakes, one of which is the earthquake in Lebak, Banten with a magnitude of 6.1. So efforts are needed to minimize the risk of earthquakes, such as observing short-term predictions through the phenomenon of the earth's magnetic field. The purpose of this study is to analyze whether there is an anomaly of ultra low frequency (ULF) geomagnetic signals before an earthquake occurs. This research uses geomagnetic data from January to February 2018 in Lebak, Banten with the method used is detrended fluctuation analysis (DFA). Observations made in this study are advanced studies based on previous research conducted with the spectral density ratio method. Based on data processing, the value of α is obtained for each component, for component H obtains the value α = 1.99, components D and Z get the value α = 1.2 to 1.6. Based on the analysis of the three components, it shows a decrease in the value of α presented by panel components D and Z. At the same time, the spectral density ratio results in an increase in the value of the Z / D ratio. The value of the DST (Disturbance Storm Time) index indicates that there was no global geomagnetic storm activity before and during the earthquake M = 6.1. The results obtained indicate that there is an anomaly of ultra low frequency (ULF) geomagnetic signal anomaly 7 and 11 days before the magnitude 6.1 earthquake.

Abstract

Abstrak Telah dilakukan pemetaan tingkat pencemaran air sungai siak sebelum dan sesudah melalui sistem filtrasi dengan 2 kali penyaringan berdasarkan parameter fisis. Pemetaan dilakukan berdasarkan nilai Konduktivitas, TDS, dan nilai pH dari sampel air yang diambil dibadan air sungai siak, baik sebelum dan setelah proses filtrasi menggunakan saringan pasir lambat yang dibuat dengan bahan utama pasir kuarsa, batu zeolit, batu bioring, arang, busa penyaring dan kerikil. Pengambilan sampel air dilakukan di atas permukaan air Sungai Siak pada 2 sisi sungai yaitu daerah sebelah Utara Sungai Siak di Kecamatan Rumbai Pesisir diambil sebanyak 15 titik sampel, dan sebelah Selatan Sungai Siak di Kecamatan Senapelan diambil sebanyak 15 titik sampel. Pengukuran dilakukan menggunakan konduktiviti meter, dan pH meter, sementara nilai TDS diperoleh melalui perhitungan menggunakan nilai konduktivitas. Hasil pengukuran 30 titik sampel sebelum proses filtrasi menunjukkan daerah B dengan nilai konduktivitas rata-rata 41,3µS/cm, dan nilai TDS rata-rata 26,45mg/L memiliki nilai yang lebih rendah dari daerah A yang memiliki nilai konduktivitas rata-rata 63,93µS/cm dan nilai TDS rata-rata 40,9mg/L. Setelah proses filtrasi dilakukan nilai konduktivitas rata-rata sampel daerah A naik menjadi 204,7µS/cm dan daerah B naik menjadi 156,3µS/cm, kenaikan yang sama terjadi untuk parameter TDS, dan pH. Peningkatan nilai konduktivitas, TDS, dan pH masih berada dibawah ambang batas sehingga sistem filtrasi dengan 2 kali penyaringan berhasil mengubah air Sungai Siak menjadi air bersih.  Abstract Mapping of the level of pollution of Siak river has been carried out before and after through the filtration system with 2 times of filtering based on physical parameters. Mapping is done based on the conductivity value, TDS, and pH value of water samples taken in the Siak river water, both before and after the filtration process using a slow sand filter made with the main ingredients of quartz sand, zeolite stones, bioring stones, charcoal, filter foam and gravel. Water sampling was carried out on the surface of the Siak River on 2 sides of the river: the area north of the Siak River in Rumbai Pesisir District was taken as many as 15 sample points, and south of the Siak River in Senapelan District was taken as many as 15 sample points. Measurements were made using conductivity meters and pH meters, while TDS values were obtained through calculations using conductivity values. The measurement results of 30 sample points before the filtration process showed area B with an average conductivity value of 41.3 µS / cm, and an average TDS value of 26.45 mg / L had a lower value than region A which had an average conductivity value of 63 , 93µS / cm and an average TDS value of 40.9 mg / L. After the filtration process the average conductivity value of the sample area A increased to 204.7 µS / cm and area B increased to 156.3 µS / cm, the same increase occurred for the TDS parameters, and pH. Increasing the conductivity, TDS, and pH values are still below the threshold so that the filtration system with 2 times of filtering succeeded in changing the Siak River water into clean water.
