Abstract
Tray dryer is one type of plate-shaped dryer, which is often used to dry materials in the form of solid or paste, therefore the tool is very suitable for drying or converting hydrogel to silica. The working principle of the dryer is to transfer heat around the environment of the material to be dried by means of heat transfer by convection and conduction. Weight reduction due to water loss due to evaporation when drying process is done. In this research, the silica to be dried was made from bagasse using a number of additional ingredients namely hydrochloric acid and sodium hydroxide with various variations. Tool performance is determined based on the amount of thermal efficiency obtained where thermal efficiency is a percentage of the amount of heat flowing during the drying process. In addition, the rate and time of drying will also affect the quality of the product. research steps include; tool design using the functional approach method to find out the functions of the unit of equipment used and structural approach to get the dimensions of the tool Silica gel produced from the drying process is analyzed using X-Ray Difraction (XRD) and Fourier Transform Infra Red (FTIR) which aims to characterize the crystal structure and detect functional groups. Based on the analysis results obtained silica gel has a functional group of Si-OH and amorphous crystal structure, so it is categorized as meeting the standards of JIS-0701. Calculation results obtained optimal conditions achieved at the time and speed of drying 360 minutes, 0.019 kg / hour m2 with a silica gel moisture content of 0.81% and thermal efficiency of 86.4%.

Published: May 2020

Abstract
This research aimed to examine the distillation of patchouli oil using firewood (FW) and Liquefied Petroleum Gas (LPG) as fuel. The effects of yield, patchouli oil quality and cost analyses had been observed. The results showed that distillation of patchouli oil using FW obtained a higher yield than LPG. Physical-chemical properties test (color, specific gravity, refractive index and optical rotation) showed no significant difference of value and still met the requirements parameters in SNI 06-2385-2006. Meanwhile, chemical component analysis by GC-MS showed that the patchouli alcohol using FW and LPG has not met the requirement parameters in SNI. Cost analysis indicated that the distillation of patchouli oil using LPG was not profitable because of higher cost and lower yield than FW.

Authors: Sutarto T E 
Published: May 2020

Abstract
The purpose of this study is to investigate the influence of physical properties, more specifically the bulk density and water content, to the erosional strength of streambank soils. Thirty (30) soil samples were extracted from the crest, midbank and toe of the bank at Clear Creek in Iowa City, Iowa. Out of those thirty (30) samples, six (6) samples were tested in the standard soil laboratory for obtaining their bulk density and particle size distribution, six (6) samples were tested their bulk density and heterogeneity using Gamma radiation scanning, and eighteen (18) samples were tested their erosional strengthr*f. In addition, six (6) pure Kaolinite-clay samples were constructed with various degrees of consolidation or age and water content for measuring their
T>-:f using conduit flume technique. The results of the conduit flume tests revealed an increasing trend in magnitude of Hf moving from the crest to the toe of the bank. The
T<--t values were 1.57, 1.53, and 1.92 Pa for the crest, midbank, and toe soils from the left bank. In similar order, the
Tc.f values were 1.46, 1.47, and 1.83 Pa for the soils from the right bank. A similar trend was obtained for the bulk density based on standard laboratory test and gamma radiation scanning. According to standard laboratory test, the average bulk density values for the crest, midbank, and toe of the right bank were 1299, 1618, and 1880 kg/m3. Similarly, based on gamma radiation technique, the average bulk density values for the crest, midbank, and toe of the right bank soils were 1273 kg/m3, 1594 kg/m3 and 1863 kg/m3, respectively. This agreement in the trend of
Tr-f and bulk density suggests a positive correlation between those to parameters. The results of Kaolinite-clay sample experiments demonstrated that samples with higher degree of consolidation or more age would have higher ^V. In addition, the Kaolinite-clay samples with higher water content would have lower
rct. These findings suggest the presence of spatial and temporal variability in
Ta of streambank soils. Therefore, incorporating this
Tc,i variability in modelling streambank erosion will give more accurate results.

Abstract
Concrete is produced from several materials which are mixed into one unit so it becomes like a stone. Concrete mixture consists of cement, coarse aggregate, fine aggregate, water and added or not additives. Cement as a binder when mixed with water will occur chemical reactions so that the hardening process occurs, while the aggregate serves as a filler for concrete. The use of concrete as a building material is now increasingly widespread, this shows the growing need for concrete, thus encouraging to create information about concrete mixtures. One of the innovations is the addition of copper fiber as a partial replacement for coarse aggregate in the concrete mixture. From the results of the study after the addition of copper fiber there was an increase in concrete compressive strength, elastic modulus and concrete tensile strength. The maximum increase occurs in concrete with the addition of 1% copper fiber of 0.14% of normal concrete.

The Evaluation of Semantic Mapping
Authors: Wardani Dewi 
Published: May 2020

Abstract
The increasing of the importance of links in the network of data influences the idea that links should be considered more in the mapping relational to graph model. Semantic abstraction gaps often occur during the mapping process where the link in the real world is mapped as a node in a graph model. This paper focused on evaluating the result of mapping and converting without losing the semantics. We propose the evaluation of our approach by using schema.org as the semantic standard. The experiments in three data sets show that the semantic mapping approach is pretty effective. We obtain quite good score matching without considering the gap index (the average is 0.6922) and with considering the gap index (the average is 0.5264) and the average precision score, 0.7042, is pretty good too.
