Abstract

Preparation and characterization of magnetite Fe3O4-palm shell activated carbon composite has been carried out as an adsorbent of phenol compounds. Composites were preparation using the co-precipitation  method by mixing Fe3O4 magnetite and suspension of activated carbon in water at 2:1 ratio by co-precipitation method. The functional groups, morphology and magnetization of the composites were characterized by FTIR, XRD, SEM-EDX and VSM. The XRD characterization result showed that the irregular activated carbon diffraction pattern on the composite showed that the carbon structure was amorphous and the peak was typical of Fe3O4 at an angle of 2θ 35.3961˚ with the distance of the diffraction plane or d = 2.53387Ǻ. VSM characterization shows the magnetic properties of magnetite are super paramagnetic with the resulting magnetization value of 15.93 emu/g, the remanence value (Mr) is 1.79 emu/g and the coercivity value (Hc) is 131.64 Oe. Adsorbent used for phenol adsorption with optimum at pH 6 with adsorption capacity was       6.71 mg/g, 120 minute contact time with adsorption capacity was 9.63 mg/g and the amount of phenol absorbed reached equilibrium a concentration of 300 mg/L of phenol with an adsorption capacity is 58.6 mg/g. The kinetics parameter showed that the adsorption followed pseudo second-order model.

Abstract

This research describes the foundation standard in Muaro Jambi. The objective is to determine the subsurface structure as well as to determine the suitable foundation standards for residential buildings in Muaro Jambi. In this study, data collection is divided into 2 residential places, the first in the housing Arza Griya Mandiri and Griya Sungai Duren Indah housing. Each housing will be taking 3 geolistrik data with path length 160 m and datum point as much as 69 datum. The result of field data obtained in the form of voltage value and current value, this value is inputted into Microsoft Excel software and searched for obstacle value and ρa. Datum point value, space electrode, layer, and value ρa are combined and input into notepad software to be processed using Res2DINV software. The results show that the foundation has been built almost in accordance with soil structure and foundation of soil obtained from the research. A suitable soil layer to build a foundation is a rocky clay layer where in this study the depth of this layer varies from 1.71 m to 18.4 m.

Abstract

The Study has been done using the geoelectric wenner configuration method in Muaro Pijoan Village, District of Jambi Luar Kota, Muaro Jambi Regency. The purpose of this study were to map the resistivity and determine the ground water position in Muaro Pijoan Village. The study area is divided into 5 tracks, 2 tracks along 100 meters and 3 tracks along 200 meters. Tracks with length 100 meters has space 5 meters and the track with length 200 meters has space of 10 meters. The value obtained from the measurement is the current and potential values, the value is used to obtain the apparent resistivity. The apparent resistivity value is then inverted using Res2Dinv software into 2 dimensional form. The inversion results in 3 cross-sectional resistivity imaged with color and each color indicates a sunder ground resistivity value. Based on the rock resistivity table, ground water has a resistivity value between 30-100 Ω.m. From the cross-sectional resistivity it is found that all tracks have a potential ground water content and the location varies from 2.5 to 34.6 meters below the soil surface. The largest groundwater potential is on track 3 and the smallest is on track 5. Based on its groundwater position in Muaro Pijoan Village includes shallow groundwater.

Abstract

The production of Dye Sensitized Solar Cells (DSSC) has been done. The transparent electrode is made by mixing of TiO2 and graphite 14% (TiO2:C14%). TiO2:C14% colloid is deposited on a conductive glass substrate Fluorine Doped Tin Oxide (FTO) by spin coating method at 500, 1000 and 1500 rpm during 50 second. Then, the layer is soaked of 24 hours in dye taken from the extract of rosella. SEM and XRD characterization are performed for looking properties of DSSC materials. The efficiency of DSSC is calculated by using the characteristic circuit IV curve. The highest efficiency value is obtained when the thickest active layer (0,9 mm) at 500 rpm, the resulting efficiency is 0,014%.

Abstract

The feasibility study of Batanghari II Bridge with the value of natural frequency of Bridge using microtremor has been done. The purpose of this research is to know the bridge's natural frequency value using Horizontal to Vertical Spectral Ratio (HVSR) method and to know the relative damage to Bridge. In this study Bridge as an object because, Bridge is an alternative way that connects one place with another place separated by a river or ditch which is often used by society for activity. To get the bridge's natural frequency value using Microtremor sensor which is directly placed bridged with geopsy software to process its data and using HVSR method. The result of this research is the natural bridge frequency value of 7.40441 Hz. To determine the feasibility of the bridge compared with the standard value of the bridge frequency of 7,675 Hz and stated the state of the Batanghari II bridge is still intact from the structural and the natural frequency value of the soil on the bridge buffer of 12.7489 Hz and 13.6343 Hz that the soil type is older soil. Can be said the foundation of the bridge last long.
