The Journal is a peer-reviewed journal. The acceptance decision is made based upon an independent review process supported by rigorous processes and provides constructive and prompt evaluations of submitted manuscripts, ensuring that only intellectual and scholarly work of the greatest contribution and highest significance is published. The AIJST publishes original conceptual and research papers, review papers, technical reports, case studies, management reports, book reviews, research notes, and commentaries. It will occasionally come out with special issues devoted to important topics concerning science & technology development issues. Scopes Starting in 2016, AIJST has focused on science and engineering aspects, and therefore now AIJST considers the topics but not limited to : Engineering (Mechanical, Chemical, Civil, Transportation) Geology and Geomorphology Environmental Science (Hydrology, Pollution, Water Treatment, Soil Science, Climatology) Physical Oceanography Mathematics Physics and Geophysics Geospatial and Information Technology

Spatial Statistic Analysis of Earthquakes in Aceh Province Year 1921-2014: Cluster Seismicity Muzailin Affan; Muhammad Syukri; Linda Wahyuna; Hizir Sofyan

The purpose of this study is to apply the analysis of spatial patterns of earthquakes in the province of Aceh by detecting clusters and looking for spatial patterns locally and globally during the period 1921-2014 using GIS (Geographic Information System). The selected techniques are Average Nearest Neighbor, Moran Global Index, the Getis-Ord General G, Anselin Local Moran Index, the Getis-Ord Gi*, and Kernel Density Estimation. Each technique is implemented using GIS so that calculations can be done efficiently and quickly. The results of this study indicate that (1) The techniques can detect clusters of dots on the spatial pattern of earthquakes; (2) Both globally and locally, it shows that earthquakes clustered in the southwestern heading to the northern part of the province; (3) An earthquake with a greater magnitude generally concentrated in the district of Simeulue, the western part of Aceh Besar and northwest of Sabang

Measurement of magnetic data has been done in the area of oil seeps in the village of the Alue Punoe, with 121 measurement points as a grid within 500 m x 500 m area where each grid is approximately in 250 m2. The total magnetic field measurement has been examined by using Proton Precession Magnetometer (PPM). Upward continuation correction was applied to obtain residual magnetic field anomaly. Residual magnetic field anomaly data are mapped using the Surfer software, while subsurface models are made using the Mag2DC software. Based on the models that have been sliced from the local magnetic anomalies along the cross section of A-B and C-D from which then obtained a shallow structure which is a fault whose an approximate depth from 30 to 100 meters and three stratified media. The stratified media of the study area are interpreted as an alluvial deposit, alternating sandstone and clay and igneous rocks. Interpretation of subsurface models shows that there exists a shallow structure assumed as a fault. Expected fault has an adjacent to the manifestations which are about 50 to 70 m. It strengthens the case that the fault is strongly related to as the pathways of oil seepsfrom possibly existed petroleum system below subsurface of unknown strata

Using Landsat-8 Imagery Data on Mapping of The Seagrass Distribution in Matahari Island, Pulau Banyak District, Aceh Province, Indonesia Syahrul Purnawan; Fauzan Aulia; Teuku Khairuman

The objective of the present study was to gathers information about the seagrass distribution area using the remote sensing that retrieved from Landsat-8. Analysis of Landsat-8 image is classified into 6 classes; seagrass, coral reefs, sand, sea, and cloud. The agreement between processed image of seagrass bed and ground truth reference was 70%. The seagrass ecosystem is well distributed along the Matahari Island, with the total area approximately 44.0123 Ha.

Energy Audit of an Industry: A Case Study of Fabrication Company Olatunde Ajani Oyelaran; Yau Yusuf Twada; Olawale Monsur Sanusi

Energy is one of the major inputs for the economic development of any country. In the case of the developing countries, the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments to meet them. Energy audit will determine energy wastage and losses, and provide techniques and ways to minimize the losses. The payback period of the energy audit programmed for the industry was found to be 14 months. The energy consumption techniques suggested by the energy audit will not only minimize the losses but also reduce monthly electricity bill. The objective of Energy Management is to achieve and maintain optimum energy procurement and utilization, throughout the organization as to minimize energy costs and wastage without affecting production and quality. Energy Audit is the key to a systematic approach for decision-making in the area of energy management. It attempts to balance the total energy inputs with its use, and serves to identify all the energy streams in a facility.

The Spatial Distribution of Bed Sediment on Fluvial System: A Mini Review of the Aceh Meandering River Muhammad Irham

Publisher : Graduate Program of Syiah Kuala University

Dynamic interactions of hydrological and geomorphological processes in the fluvial system result in accumulated deposit on the bed because the capacity to carry sediment has been exceeded. The bed load of the Aceh fluvial system is primarily generated by mechanical weathering resulting in boulders, pebbles, and sand, which roll or bounce along the river bed forming temporary deposits as bars on the insides of meander bends, as a result of a loss of transport energy in the system. This dynamic controls the style and range of deposits in the Aceh River. This study focuses on the spatial distribution of bed-load transport of the Aceh River. Understanding the spatial distribution of deposits facilitates the reconstruction of the changes in controlling factors during accumulation of deposits. One of the methods can be done by sieve analysis of sediment, where the method illuminates the distribution of sediment changes associated with channel morphology under different flow regimes. Hence, the purpose of this mini review is to investigate how the sediment along the river meander spatially dispersed. The results demonstrate that channel deposits in the Aceh River are formed from four different type of materials: pebble deposited along upstream left bank; sand located on the upstream, downstream, and along meander belts; and silt and clay located along the cut bank of meander bends. Because of different depositional pattern, the distribution of the sediment along the river can be used as a surrogate to identify bank stability, as well as to predict critical geometry for meander bend initiation

The Preliminary Study on The Effect of Coarse Particles Content on OMC and Maximum Dry Unit Weight: A Case of Aceh’s Fill Materials Bambang Setiawan

Empirical evidence suggests that the percentage of coarse fraction content on soil has an influence on the soil optimum moisture content (OMC) and soil maximum dry density (MDD). This phenomenon is used as a basis to examine the characteristics of Aceh’s fill materials. The major objective of the present study is to determine the relationship between coarse-grained content and OMC and MDD of the Aceh’s fill materials. This relationship is important in the justification of soil suitability as materials for engineering construction. Thirty (30) soil samples from various locations in the Province of Aceh have been collected and tested. The tests carried out include soil physical properties tests and standard compaction test. In the case of a relationship between soil coarse fraction content and soil OMC or MDD, two general findings have been deduced. The first finding of the present study shows that the soil OMC decreases when the content of coarse-grained particles in the soil increases. The later finding shows a positive correlation between coarse particles content and the soil MDD which the increase of the content of coarse-grained particles in the soil will increase the value of the soil’s MDD. In conclusion, the coarse particles content affects the OMC and MDD of Aceh’s fill materials
