Abstract

Magnetite (Fe3O4) nanoparticles have been successfully synthesized using co-precipitation method and have been used for removing Cu, Mn and Ni metals ions from artificial wastewater. Ability of removing metal ions with Fe3O4 against pH, adsorbent particle size, readsorption and by addition of Polyethylene Glycol (PEG-4000) as coating agent of adsorbent have been studied. The adsorption process was found to be pH-dependent. Maximum adsorption at pH 12 for most of the metal ions with percent of sorption Cu 99.79%, Ni 69.83% and Mn 44.53%. Using adsorbent with 12 nm of particles size, readsorption process and by addition of Polyethylene Glycol (PEG-4000) as coating agent of adsorbent also made the ability of removing metals ions increasing. Preliminary results indicate that magnetite nanoparticles may be used as an adsorbent for removal of Cu, Mn and Ni from wastewater.

Abstract

Kepulauan Mentawai merupakan bagian dari Pulau Sumatera yang terdapat dua lempeng tektonik yang aktif. Kedua lempeng tektonik tersebut yaitu lempeng Indo-Australi menunjam ke arah lempeng Eurasia dan menimbulkan zona subduksi Sumatera yang banyak menimbulkan kejadian gempabumi. Penelitian ini bertujuan untuk mengetahui sesar gempa ditinjau dari besarnya magnitudo dengan menggunakan metode focal mechanism studi kasus gempa pada Kepulauan Mentawai periode tahun 2010-2016. Metode focal mechanism merupakan metode untuk menentukan bidang sesar yang dihasilkan oleh kejadian gempa dengan memanfaatkan gerak awal gelombang P. Gerak awal gelombang P berupa gaya kompresi ataupun dilatasi. Selain dengan metode focal mechanism, dalam penelitian ini juga dibuat cross section gempa dengan luasan daerah tertentu yang bertujuan untuk mengetahui indikasi gempa yang terjadi merupakan gempa pada daerah lempeng tektonik. Hasil solusi focal mechanism untuk data gempa bermagnitudo ≥ 6.0 Mw rata-rata gempa menghasilkan sesar naik (thrust/reverse) dengan beberapa nilai kemiringan (dip) tertentu. Sedangkan hasil dari cross section gempa menunjukkan sebaran hiposenter gempa yang cenderung menunjam. Kejadian ini adalah indikasi bahwa lokasi gempa-gempa tersebut merupakan tempat lempeng yang menunjam dan ketika dihubungkan dengan hasil focal mechanism juga menunjukkan kecenderungan sesarnya adalah sesar naik dengan beberapa nilai kemiringan (dip) tertentu

Abstract

DNA level of purity has been tested by observing the phenomenon of surface plasmon resonance (SPR) in silver film + silver (Ag) nanoparticles system as DNA sensor using Kretschmann configuration. Surface plasmon resonance (SPR) phenomenon observed in the resonance condition of reflectance spectrum vary with incident angle of laser, beamed toward prism. System is built as a model for DNA purity test instrument that give higher accuracy. DNA purity testing was conducted by placing DNA layer with various ratio on prism in order to get the angle shift value in each sample as a result. Purity level of DNA indicates the DNA quality based on the ratio between the amount of pure DNA compared to the amount of impurity materials (protein). After the deposition of DNA in ratio 1,774, 1,838 and 1,916 SPR angle shifted ,  and  respectively. Characteristic differences of DNA with different purity (ratio) are shown by reflectance value that is getting higher at a smaller ratio, indicates that in the higher DNA ratio the angle shift is getting smaller. SPR angle shift which is occurred before and after DNA deposition shows the sensitivity of SPR as DNA sensor.

Abstract

The scattering amplitudes are obtained from the phase shifts for a spherically symmetric potential using the D-dimensional Schrödinger equation and the partial wave method. Plots show that the real and imaginary parts of the scattering amplitude are almost similar behavior.

Abstract

Supercapacitor is a high power density energy storage device which complements the lack of batteries and conventional capacitors. One material which has a great potential in the manufacture of composite supercapacitor is spinel ZnCo2O4/carbon nano tube and abreviated in the later case as ZCO/CNT. Composition variations in ZCO/CNT composites is expected to the performance of supercapacitor especially the dielectric properties and specific capacitance. Inthis study the composite ZCO/CNT was made from raw materials of ZCO nano crystal which was prepared from previous research on which employing sonochemistry technic, carbon nano tube, and 1-methil 2 pyrolidine. A screen printing method was used in this experiment to deposite the composite on silver substrates. The separator in between of two identical composite structures was prepared from isotactic polypropylene. We used KOH 6 M which was implemented as electrolyte of the composites. Characterization of composite structures has been performed using X-RD, while the morphology characterization using SEM. It was found that the dielectric supercapacitor increase by increasing of mass fraction of ZCO in the composite. Thehighest dielectric constant is reached at 1.89 x 106 and the specific capacitance of 81 F/g for 3:1mass ratio of ZCO : CNT at 100 Hz.

Abstract

The increasing emission of CO2 in the air has led to the need to measure the gas content on a regular basis. The gas accumulates slowly in the layers of Earth's atmosphere. However, this need is constrained by a number of issues that later affect the accuracy of the mapping which includes the continuously circulating gas in the atmosphere. Researchers suspect that the amount of CO2 and other gases is getting higher due to the many additional human produced carbon emissions from burning fossil fuels. In this study climate change analysis was conducted in Semarang. The study looks deeper in the CO2 variability data from referencestudies and performs analysis of climate data from rainfall and CO2 measurement data of Semarang.

Abstract

Identification of aquifer layer location has been done using Schlumberger configuration of geoelectric resistivity methods in Masaran District. Data collection was performed using resistivity meter OYO Mc-el-ohm series 2119c having a length of current electrode (AB / 2) from 1.5 m to 350 meters. Data processing was done using software IP2win. The purpose of this study was to identify the location of confined aquifer and unconfined aquifer. The result showed that litology of aquifer layers were detected as clayed sand, sands and gravel sands. The depth of confined aquifer was detected for TS1 (4.52 meters to 8.57 meters and 22.4 meters to 34 meters), TS2 (8.84 meters to 20.9 meters), TS3 (2.87 meters to 10 meters and 13.3 meters to 41.5 meters), TS4 (20.09 meters to 6.71 meters and 17.3 meters to 36.4 meters) and TS5 (6.3 meters to 25 meters). The thickest layer of confined aquifer was TS3. While, the depth of unconfined aquifer was detected for TS1 (68.1 meters to 78 meters and 94.3 meters to 115 meters), TS2 (36.9 meters to 93.4 meters and 103 meters to 134 meters), TS3 (72.8 meters to 101 meters), TS4 (46.3 meters to 67.5 meters and 82.1 meters to 98 meters), and TS5 (50.1 meters to 93.5 meters and 99.7 meters to 111 meters). The layer thickness of unconfined aquifer were detected for TS1 (30.6 meters), TS2 (86.7 meters), TS3 (28.4 meters), TS4 (37 meters), and TS5 (55 meters). The layer thickness of unconfined aquifer that has the thickest was TS2.
