Abstract: |
A
geotechnical investigation of cavity and settlement has been conducted
at Besraya Highway, Jln Kuchai Lama due to pipe jacking works to
determine subsurface condition at the proposed site and to identify the
causes of settlement. In this research study, JKR Probe test and
Electrical Resistivity Imaging (ERI) method were applied in order to
achieve the objectives. Analyses of the settlement problem also were
carried out based on soil parameters obtained from JKR Probe data using
Two-Dimensional (2-D) finite element method (FEM) analyses with PLAXIS
Finite Element Code. Based on JKR Probe test results, it is found that
the soil layer is loose to medium dense for middle of line. While for
line 1, the soil was found in fully saturated condition since there is
an evidence of water pocket when the rod was pulled out from the ground.
For ERI results, the soil layer was found very weak with presence of
saturated condition. Besides that, there is an appearance of water
pocket based on images of ERI resulting formation of cavities and voids
which beneath the existing pavement structure. From the geo forensic
stimulation, the development of excess pore water pressure and seepage
in the loose unconsolidated deposit provide additional volume change to
the material, causing excessive settlement. The results indicated that
the groundwater seepage and dissipation is the main problem to the
ground settlement issue with the contribution of pipe jacking work.
Therefore, a mitigation step is a need in order to stop the major
failure occur due to excessive settlement. |

Author (s): |
Devi Fitria, Lenny Marlinda, Rahmi, Yustia
Mirzani Wulandari and Muhammad Al Muttaqii |
Abstract: |
Factories used palm oil solid waste in empty bunches, shells, and fiber
(coir) as boiler fuel. The combustion process in this boiler produces
by-products in the form of fly ash and bottom ash. Oil palm fly ash and
bottom ash content were 37.98% (100 kg/week) and 64.36% (3-5 tons/week),
respectively. After refluxing of fly ash, the SiO2 content of 96.8% is
used to synthesize ZSM-5. The synthesis was carried out with the aging
variation of 6, 12, and 24 h, and without aging time at the temperature
of 60 0C. The hydrothermal was carried out at a temperature of 150 0C
for 10 and 18 h. The results show an amorphous phase over 10 h
hydrothermal, and ZSM-5 has formed over 18 h hydrothermal. ZSM-5 was
formed and sodalite phase without aging time for 18 h hydrothermal.
Analcime and sodalite formed for 6 h aging time. ZSM-5, analcime,
faujasite, and sodalite formed over 12 and 24 h aging time. With a
longer time of aging, the analcime phase dominated. It caused the
metastable MFI structure to open to transform into alumina-rich
structures. The morphology of ZSM-5 synthesized with hydrothermal 18 h
with 6 h of aging is spheric and trapezohedron. |

Title: |
Overview on directional drilling wells |
Author (s): |
Busahmin Bashir, Marek Piaskowy and Gamal
Alusta |
Abstract: |
Drilling a well is a cost intangible, because a well costs millions of
dollars, so the more dollars that is spent in a well, the more oil and
gas has to be produced over the life of a well. If costs are not
accurate, the economics change after a well has been drilled, as a
result, the estimated costs are risked i.e. a success factor is placed
on the well. The lower the factor, the lower the chance of success and
an estimated cost can change the risk profit of any well. These days the
improvement of drilling technology is so challenging, however most of
the wells drilled in around the world directional wells are. For
effortlessness, a directional well is one that is not vertically drilled
purposefully or inadvertently. As drilling activity expands more and
more places are becoming inaccessible hence the need for directional
drilling. It is essential to comprehend the requirement for directional
wells, as well as planning and execution. The idea of directional
drilling has changed the way wherein wells are drilled everywhere today,
from simple deviated wells to horizontals and multilateral wells; the
wells made an unavailable areas accessible while increasing the area for
drainage by each well drilled, with the wide application of such methods
in the world. This paper represents an overview for directional wells
with emphasis of the application using real field data, a case study
from Poland related to J-shape, S-shape drilling profile .Moreover,
directional and horizontal drilling provides more access to the oil
reservoirs, thereafter more oil will be produced over vertical wells. |

Title: |
Use of bottom ash waste of a thermal power
plant for producing a construction binder |
Author (s): |

Ismailova |
Abstract: |
Efficient and rational use of ash and slag waste from a thermal power
plant for the production of building binders is primarily determined by
their quality properties, as well as the technology used and its optimal
parameters. This article is devoted to solving these issues. The results
obtained showed that ash and slag from the TPP of SSGPO JSC (Rudny,
Kazakhstan) are effective materials for obtaining slowly hardening and
cement-containing binders from them, used for the construction of the
bases of road pavements. To study the physical and mechanical properties
of binders, samples of 10x10x10 cm were made, hardened for 28 days under
normal conditions. It has been established that the cement-ash-and-slag
binder with the addition of 20 to 50% ash and slag has an activity of
25-37 MPa, and in terms of efficiency, as a binder, it surpasses the
slowly hardening ash-and-slag binder. On the basis of a cement-ash and
slag binder, it is possible to make a concrete mixture for the
construction of the bases of road pavements of any category (the ratio
between SHGPS: TsZShV can be 1: 5; 1: 4; 1: 3; 1: 2; and 1: 1). In this
case, the strength of the bases can vary from 2.8 ... 14 MPa (for a
mixture of 1: 5 composition) to 9 ... 17 MPa (for a mixture of 1: 1
composition). To determine the optimal parameters of the developed
technology for producing a cement - ash and slag binder, a methodical
approach based on probabilistic-deterministic planning of the experiment
was used. In accordance with the plan of the experiment, 16 laboratory
experiments were carried out to obtain cement-ash-and-slag binders, for
each of which the mobility of the cement-ash and slag test was
determined. From the obtained binders of various compositions,
samples-beams with a size of 4x4x16 cm were also made, which, after
holding for 28 days under normal conditions, were tested for bending and
compression. It has been established that the optimum technology
indicators are achieved when the cement content in the ash-and-slag
mixture is 50%, the mixing time of the dry mixture is 9 minutes, the
water-binding ratio is 0.35, and the mixing time of the wet mixture is 5
minutes. At the same time, the binder of optimal composition has
sufficient strength after 28 days of hardening, allows to reduce cement
consumption and provides increased homogeneity and mobility of mixtures
in dry and wet state, which facilitates technological processes for
preparing hardening systems (bending strength - 4.7 MPa; compressive
strength - 34.4 MPa and the mobility of the cement-ash and slag test is
4.5 cm). |

righting arm stability for traditional fishing vessel under loading |
Author (s): |
S. F. Khristyson, J. Jamari and A. P.
Bayuseno |
Abstract: |
The
designed hull form of the ship may influence the stability of the ship
floating in the water. The existing equipment may affect the operational
performance of the ship in which the height of the draft of the ship
controls the floating ability and comfortable stability. The purpose of
this research was to obtain the stability data from the traditional
fishing boat models with various standard sizes according to the ratio
of width/draft (D /B). An optimal design output was computed to meet the
various criteria required for the design using computational software.
The resulting comparison of trim (TF or TA) showed that the movement of
the point of gravity is relatively small. This indicates that the
influence of ship movement and external forces either from sea waves or
wind has a high enough on changes in the center of gravity. Therefore
the effect of using the (D/B) value ratio greatly determines the comfort
and stability of the ship when operating to the fishing ground. |

Abstract: |
Cocoa
butter consist of stearic acid, oleic acid, palmitic acid, linoleic acid
and vitamin E. It can be used as additional ingredient or raw material
for cosmetics formulation in emulsion form. One of the emulsion type
that widely used as base for skincare product is water in oil (W/O)
emulsion. The purpose of this study was to evaluate the effect of water
concentration on the W/O emulsion and its stability based on cocoa
butter for cosmetic raw material. W/O emulsion was made by mixing water
phase in oil phase at temperature 700C until homogeneous for 1 hour then
allowed to harden at room temperature. In this study the water
concentration were varied 12%, 16%, 20%, 24%, 28% and 32%. The
characterization carried out were physical appearance, hardness,
homogeneity, droplet size, melting point, chemical functional group and
sensory test. The study showed that water concentration affected W/O
emulsion final product in parameter of texture, melting point and
droplets size. The formulation with higher water content produce softer
texture, lower melting point, lower hardness and increase droplets size.
However, all formulation showed good homogeneity and stability for 5
weeks observation at room temperature. There was no significant change
in color, aroma and consistency of physical appearance and there was no
phase separation occurred. The absence of evolution in FTIR spectra also
indicated that the W/O emulsion also chemically stable during the
storage. Finally, the formulation assessment was done based on the
sensory test where the formulation with water content 20% was the most
preferred formulation with an average score of 6.61. |

Energy efficient Clustering using PSO and
Fuzzy logic for Hybrid MANETs |
Author (s): |
V. Sowmya Devi, Nagaratna P. Hegde and
Niranjan Kumar |
Abstract: |
In
MANETs, development of an energy efficient routing protocol is
essential. The cost of the network depends on the energy consumption of
each mobile node. Overutilization of energy by a mobile node cannot
contribute to the utility of the network as a whole. In order to
optimize the utilization of energy at each node, we propose an Energy
efficient Clustering using PSO and Fuzzy logic for Hybrid MANETs (EC-PFHM).
It can minimize the energy consumption and increases the network
lifetime. In our proposed approach, an energy efficient cluster head
selection is performed using particle swarm optimization (PSO), where
the nodes with high residual energy and connectivity are elected as
cluster head (CH). Appropriate super cluster head (SCH) is selected by
using fuzzy logic. By this the overall networks overhead is reduced and
hence the QoS of the network is enhanced. The result obtained through
NS-2 simulation shows that the proposed algorithm performs better than
FQ-MP-OLSR and BPSO-TORA approaches in terms of reduced energy
consumption, delay and increased throughput. |

Abstract: |
The
Indonesian state has abundant fertile land and is the main producer of
various tropical agricultural products. One of the important
agricultural commodities in Indonesia is rice. In planting rice,
processing equipment such as tractors is needed. Tractor wheel fin is
the most important part of a tractor for plowing fields. Damage to the
tractor wheel fins due to the lack of ability of the tractor wheel fins
to withstand loads and is caused by the age of the fins themselves.
Previous research has made a bending tool that can also be used to form
the fin wheel of a hand tractor with a hydraulic system, with one stage
of the bending process, two embossing in the shape of a radius as
reinforcement. Therefore, this study was conducted to see how the effect
of embossing on the flexural strength and hardness of the tractor wheel
fins using a variation of the triangular embossing model, the number of
embossing 1, and the embossing height of 4, 5, 6 mm with carbon steel
(St 42), plate thickness 3.8. mm. Based on the results of research
conducted, the higher the embossing, the greater the resulting maximum
load, where the maximum load is obtained by the tractor wheel fin with a
triangular embossing model, and the embossing height of 6 mm, the
bending stress is 147.143 N/mm2. The hardness test results of the
tractor wheel fin with a triangular triangle model, height 6 has the
greatest hardness, namely 171.43 HB. |

Al-Salam A. Al-Masgari and Moataz Kh. Barakat |
Abstract: |
The
underneath Upper Qishn clastic sediments, which they revealed in the
Sharyoof oilfield has been perfectly investigated. The Upper Qishn
clastic reservoir petrophysical properties such as the saturation and
porosity were evaluated utilizing well logs data. The findings were used
to assess the importance of the reservoir and hydrocarbon capacity. The
Upper Qishn Clasty lithology has been estimated utilizing well logs,
which they infer that the lithofacies of this interval is consist mainly
of carbonate, sandstone, and low-shale intercalation. The wireline
logging data had been carefully evaluated during the processing of the
data; therefore, data quality was thought to be good. The findings from
the porosity reservoir tested for six wells indicate an overall average
porosity of 14.62% to 24.2%, while the relative permeability is 11.98%
to 18.2%. Nevertheless, the water saturation of the reservoir varies
from about 50 to 84.1%. Saturation of hydrocarbons, on the other hand,
is in reverse relation to saturation of water. Based on the on these
investigated outcomes, this reservoir interval been interpreted as an
excellent reservoir with high median of efficient porosity reach to 20%
and high hydrocarbon above 50 %. The Upper Qishn clastic reservoir
demonstrates excellent potential of the reservoir, particularly the
topmost reservoir component to be properly considered in upcoming
oilfield development. In the Upper Qishn clastic reservoir, the
hydrocarbon saturation map shows an ordinary distribution pattern, with
an overall rise to the north - west, and east direction, as they
decrease into southwestern wards. |

Abstract: |
The
purpose of the study is to simulate the combustion of coal dust in real
combustion using artificial neural networks. The article discusses
optical methods of flame diagnostics. The focus is on the secondary air
supply. For unknown reasons, the pulverized coal in the boiler is not
completely combusted. Incomplete combustion of coal impairs the
efficiency of the boiler, that is, it worsens the combustion efficiency
and leads to significant costs. The scientific novelty consists in the
use of artificial neural networks in control algorithms, making it
possible to simulate efficiently complex processes, in particular the
process of burning coal dust. In the Matlab software environment, the
results of the data collection with the separation output with different
amplitudes are shown. The considered scheme takes into account the
multi-input and multi-output nature of the combustion process. Using
additional information, vector-based optical signals for the flame
surface area and the loop length have proven the system tracking
properties. As a result of the use of fast optical signals, the control
speed of the object increases and stabilization of the output signals of
the combustion process is achieved. |

Abstract: |
The aim
of this work is to analyze the effects of the core and loop (external)
time constants on the delayed-neutron precursors in fluid-fueled molten
salt reactors (MSR). A 0-D mathematical model of neutron precursor
concentration and neutron power without feedback effects is used for
this analysis. For different time constants, we present the behavior of
the precursors concentration, thermal power, and the external
reactivity. According to the obtained results, we find that the external
reactivity is small for large time constants in the core and in the

Author (s): |
Romel B. Cristobal |
Abstract: |
Solar-powered and direct current energized households can be a smart
choice in resorting to renewable energy. The cost of electricity
continues to rise due to the rising cost of fuel used to generate
electricity, depleting sources of fuel, and the adverse effect of some
energy sources used to generate electricity. A survey on household's
selected electrical parameters, development, and testing of a strategy
of shifting and converting the lighting system of households from 220
volts alternating current (AC) to 12 volts direct current (DC), and
solar was conducted. The results showed that the majority (53.85%) of
the households' lighting system can be converted and the conversion
strategy is technically feasible. The solar and DC lighting system also
projected a savings of 326.70 pesos per month, with an estimated ROI of
27.6 % and a payback period of 3.62 years under the Philippine
conditions. The shifting or conversion strategy showed excellent
potential as an alternative lighting system not only for households but

Author (s): |
Syaiful Syaiful, Hermanto Siregar, Ernan
Rustiadi and Eri Susanto Hariyadi |
Abstract: |
The
main problem of cities in Indonesia is transportation, one of which is
traffic. Motorized vehicle traffic that passes through a network affects
the road's ability. Traffic flows and patterns of movement of urban
residents are very diverse. Road handling is based on the high volume of
vehicles, traffic density and the impact on the low speed. The decrease
in vehicle speed results in optimal utilization of the road segment. The
research was carried out in two data collections, the first was data
collection in the densely populated area of Bogor city and in the
potential area of Bogor district. Furthermore, in the buffer zone of the
city and district borders for each selected location, 5 (five) locations
were identified, at 1) intersection the three-arm signaled of the
Salabenda in Kemang, 2) intersection the four-arm signaled of the
Semplak in Semplak, 3) intersection the signalized the three arms of the
Bubulak in Bubulak, 5) intersection the four-arm signaled of the POMAD
in Ciluer and 5) intersection the four-arm signaled of the Ciawi in
Ciawi. This study aims to obtain a strategic model of traffic
engineering decision making in the transportation system. The technology
criteria place a standardized and mutually supportive system for
decision making. The real and supportive condition is technology.
Experts agree that to model the strategic concept of traffic engineering
in the transportation system is to focus on TECHNOLOGY criteria.
Technology occupies the first level of 0.456%, so technology is a
benchmark in the management of modern transportation that should be
relied on. Technology both in terms of traffic engineering, APILL and
geometric conditions as well as public transportation with the concept
of multi-mode and mass public transportation as a substitute for public
transportation that is no longer feasible to operate. The results of the
pairwise comparison assessment of the five criteria above show that the
value of the consistency ratio is 0.085, meaning that < 0.1, which is
required by Saaty, has met. Where Saaty sets the Consystency Ratio (CR)
value to be less than 0.1, so that the pairwise comparison calculation
fulfills. |

Palomino and Daniel Suesczn-Diaz |
Abstract: |
Average
reservoir pressure is a parameter of importance for design, assessment,
evaluation, and exploitation of hydrocarbon reservoirs. By excellence,
pressure buildup tests are intended for obtaining a measurement of this
property. Recently, drawdown tests have been shown to provide the
average reservoir pressure by mathematical manipulations of pressure
behavior and material balance equations. In this paper, an extension of
the TDS Technique is used on drawdown tests for the determination of an
expression to obtain an estimation of the average reservoir pressure for
horizontal wells in homogeneous and anisotropic formations using an
approximation of the pressure behavior in hydraulically-fractured
vertical wells. The equation was successfully tested with synthetic
examples. |

Design and development of a collision
resistant modified SHA1 |
Author (s): |
Esmael V. Maliberan |
Abstract: |
The
Secure Hash Algorithm is best used in checking data integrity and
authenticating digital media due to its fast hash calculating power.
However, the SHA1 hashes are highly vulnerable to different attacks most
especially collision attack because of the undersized hash length that
compromises the integrity and confidentiality of data during transit.
Presented in the current study is a new design to extend the hash size
of SHA1 to secure a client-server communication through login
authentication. Experimental results revealed that on five datasets that
have collision in SHA1, none of them collided using the enhanced SHA1.
Furthermore, the enhanced SHA1 is more resistant to brute force attack
over the original SHA1 in terms of cracking time which is estimated to
be sexagintillion years on a standard desktop PC. The results also
presented that the produced hash codes of the enhanced SHA1 were
resistant against a rainbow table and dictionary attack. By increasing
the hash value of SHA1 from 160-bits to 1280-bits using AND and XOR
operators, this paper has shown that execution of the enhanced SHA1 in
digesting the passwords in login authentication delivers a safe way in a
web transaction particularly in web-based environment. |
