Published: December 2019

Abstract
The gastropod is one class of the Mollusca phylum using the abdomen as the leg. Generally gastropods are crawling on the bottom of the waters and submerged in the mud and are often called epifauna and infauna gastropods. Research on diversity of epifauna gastropods in the littoral zone has been done in Mesjid Raya, Aceh Besar District. This research aims to determine the diversity of gastropod species based on the substrate types (coral reef, muddy and sandy). The exploratory method by using transect line was used in this study. In each substrate, a line transect was drawn for five transects with a length of 50 m. The transects were started from the tidal line. The distance between transects were 50 m. Each transect was made in 10 sampling plots measuring lm × lm, and the distance between plots was 5m. The gastropods were collected directly and without damaging the substrates. The epifauna gastropods obtained was put into a sample bottle and preserved using 70% alcohol. The results showed that 23 families and 54 species of epifauna gastropods were identified. The number of species of gstropods was found in the sandy and muddy substrate more than in the sandy and corral reef substrate, but the highest diversity index was found in the sandy substrate, meanwhile the lowest diversity was found in the coral reef substrate. The highest species density was obtained on Rhinoclavis aspera.

Published: December 2019

AbstractGeophysical surveys have been conducted using magnetic in the archaeological site of Kuta Lubok fortress, Aceh Besar. The fortress was built in 13th century by the Lamuri Sultanate in the northern part Aceh coast. To map an estimated area of archaeological objects, 420 stations have been measured. The data were measured by 21 profiles across of the area with the length of profiles vary from 40 to 60 m. To get a complete resolution, data is taken with a distance of 20 m between lines and a distance of 5 m between stations. From the total magnetic field map that has reduced to the poles, the anomaly is generally able to delineate buried building sites. Then based on Euler deconvolution analysis, the structure of the fortress building can be seen using a 5-meter depth level. But a clearer structure is seen in the use of 10 m in depth. Based on the interpretation of the two tolerance layers it can be concluded that the Kuta Lubok fortress was found stretching parallel to the line along the 400 m to the east of the fort building which is still intact.
One-dimensional magnetotelluric inversion using levenberg-marquardt and particle swarm optimization algorithm
Authors: Darisma D , Marwan  
Published: December 2019

Abstract
Magnetotelluric is a geophysical method which uses natural time variations of the Earth’s magnetic and electric fields. One-dimensional magnetotelluric inversion was carried out to estimate the electrical resistivity distribution of rocks which varied with depth. Non-linear relationships between model parameters and observation data lead to difficulties in the inversion process. This problem can be solved with a non-linear inversion method with a global search technique. One of the global search technique that gaining interest in the inverse problem is Particle Swarm Optimization (PSO). PSO can find acceptable solutions from a very broad set of initial parameters. This study also carried out a non-linear local search technique, namely Levenberg-Marquardt (LM) which has been used globally for the geophysical problem. Then the two inversion algorithm was compared in determining the best model solution. There are two data used in this study which are generated from a three-layer model, namely data without noise and also data that has been added by Gaussian noise with 10% standard deviation. It was found that the results of the two inversions were quite good at determining the actual model. LM algorithm is an algorithm that is truly influenced by the initial value of the damping factor

Published: December 2019

Abstract
The use of solar energy using solar panels began to be encouraged. Solar panels utilize solar radiation and convert it into clean and renewable energy. The problems of the accuracy of the panel facing right towards radiation are a challenge in the development of a driving system. Solar panels have limited motion, which is a maximum of phi, so that wind disturbances are very dangerous for motor drives and solar panels. This paper aims to eliminate wind disturbances in solar panel drive systems. The fuzzy logic control is used to determine the amount of power given to the driving motor to direct the panel towards solar radiation. Inputs and outputs of fuzzy controllers are arranged by dividing into each of the five members. Simulation results show that the position error of solar panels without wind disturbances reaches 0.3325° in zonal and 0.5210° in meridional. By using wind disturbances, this system managed to maintain errors smaller than 0.4285° in zonal and 0.6116° in meridional. After modifying the rule base and membership function, systems show decreasing of error half of recent trial.

Published: December 2019

Abstract
The sustainable development requires the provision of adequate infrastructure, but the construction activities on infrastructure development itself still have been considered as a sector that has a negative impact to the environment. The implementation of the sustainable construction becomes a necessity, but the implementation of the sustainable construction in developing countries is still very limited, since there are still many factors that inhibit the implementation of this concept. This study aims to analyse the barriers in the implementation of sustainable construction in the infrastructure development projects in Palembang, Indonesia. The barriers are identified based on the results of literature studies. The survey using a questionnaire was conducted to state-owned and private companies that were carrying out infrastructure development projects in Palembang and its surrounding areas. The survey confirms the various barriers that may occur based on the perceptions of respondents representing state-owned and private companies. The mean item score was used to determine the ranking of each barrier. This study indicate that the following factors are the main barriers to the implementation of sustainable construction, namely factors related to the limited number of trained and/or certified workers and lack of communication between parties involved in the project.

Published: December 2019

Abstract
This study emphasis on the optimization of the operating parameters viz. gear fabrication technique, rotational speed and applied torque on fabricated gears to improve their performance. Polymer gears are injection molded using conventional and horizontal centrifugal casting technique known as homogeneous and FGM gears, respectively. Material used to fabricate the gear is High Density Polyethylene (HDPE). Taguchi technique is used to optimize the performance output of homogeneous and FGM gears with respect to input parameters such as torque and rotational speeds. Three different rotational speeds of 400, 700 and 1000 rpm along with three different torque levels of 1, 2 and 3 Nm are selected for this investigation. Number of cycles of 1.5×105 was fixed for the experimentation. The influence of input control parameters on performance output is analysed by ANOVA analysis. The results finding show that the thermal behavior of gear is very much affected by torque whereas the specific wear rate (WR) is utmost pointedly influenced by the gear fabrication technique i.e. FGM gear has small tooth wear in the compression of homogeneous and neat HDPE gears.

Authors: Reddy Anand S. , Kumar Agarwal Praveen , Chand Satish 
Published: December 2019

Abstract
Active magnetic bearings (AMBs)are mechatronic systems to support the rotors without any physical contact. Compact AMBs are required for better performance. Present work aims at optimization of AMB for achieving the compact size. Genetic algorithms (GAs) are mostly used for the optimization of such nonlinear design problems. However, GAs with fixed parameters may result in convergence to local optimal solutions and sluggish convergence speed.To remove these deficiencies, the adaptive multipopulation genetic algorithm (AMPGA) is used for the optimization of AMB in the present work. In this algorithm, crossover and mutation probabilities and migration rateare regulated based onpopulation diversity. In addition, real-encoded chromosomes are used. Performance of the designed AMPGA is studied in terms of the convergence speed and optimal solution. It is found that AMPGA converges at a faster rate and gives a better optimal solution than both multipopulation genetic algorithm (MPGA) and simple genetic algorithm (SGA). The optimal value of the AMB size obtained by AMPGA is found to be smaller than that obtained by MPGA and SGA.

Published: December 2019

Abstract
Automisation of agricultural processes provides the benefits of increased efficiency, productivity, healthy crops, efficient use of resources & material and labour cost savings. In this paper, an autonomous seed-sowing robot is designed to cope up the above goals. The robot divides the field into a grid with intersection points as places where the seeds are sown. The depth of the hole, the distance between points where the seeds are sown is calculated according to government data and is fed to the logic board of the robot. The robot goes to the starting points and makes a hole using a toothed wheel with teeth of increasing height. The delivery system makes sure that only one seed is dispensed per hole and the back plate mechanism fills the hole after sowing is done. Sensors are used for obstacle detection and robot changes its path accordingly. There are several robots available in the market and research has been done on many more, that perform the above functions separately but no one has integrated all the above functions in one system. The proposed robot does this and provides a better solution for low productivity nations.

Abstract
Bio-diesel has become more popular in recent timesas of its low after emissions and due to its extraction from renewable resources. Transesterification process is used to extract the bio-diesel from oil either by edible oil or by non-edible oil. The use of biodiesel has created a constructive effect in solving issues of decrement in petroleum stocks. Biodiesel can be extracted with the use of edible &non-edible vegetable oils. However, use of edible oils can threaten the food storage, so non-edible oil, which is also acknowledged as second-generation feedstock, can be used as another option in extraction of biodiesel from oil. This paper has explained in detailed some of the categories of non-edible vegetables oils have higher quality of biodiesel. In this review, an endeavor has done on bio-diesel production of various non-edible oil and its influence on internal combustion engines performance and emissions characteristics.
