A swarm robotics system can consists of at least two or up to hundreds or thousands number of robots. To build a system that is able to perform target searching task, it needs a robust algoritm and communication strategy. A wrong strategy can lead to unsatisfactory performance in which the swarm robots would unable to move efficiently and arrive at the target position precisely. This work aims to develop a new method for target searching strategy for swarm robotics system by adapting Extended Bat Algorithm (EBA) to the system. EBA is the low level hybrid algorithm of Bat Algorithm (BA) and Spiral Dynamic Algoruthm (SDA), and therefore its exploration and exploitation method is better than BA and SDA. EBA had proven its ability to solve general mathematical problem, however, for swarm robotics system application, its performance and effectiveness still needs to be comprehensively investigated. The investigation result shows that EBA can prove its potentiality to develop the best target searching strategy to the swarm robotics system with 5 number of iterations within 49 seconds. This is found to be the lowest number of iterations in the shortest of time. The accuracy is 99% to arrive at the desired location. Hence, the proposed EBA method is able to perform a target searching task for swarm robotics system.

Target searching is a well-known but difficult problem in many research domains, including computational intelligence, swarm intelligence, and robotics. The main goal is to search for the targets within the specific boundary with the minimum time that is required and the obstacle avoidance that has been equipped in place. Swarm robotics (SR) is an extension of the multi-robot system that particularly discovers a concept of coordination, collaboration, and communication among a large number of robots. Because the robots are collaborating and working together, the task that is given will be completed faster compared to using a single robot. Thus, searching for single or multiple targets with swarm robots is a significant and realistic approach. Robustness, flexibility, and scalability, which are supported by distributed sensing, also make the swarm robots strategy suitable for target searching problems in real-world applications. The purpose of this article is to deliver a systematic literature review of SR strategies that are applied to target search problems, so as to show which are being explored in the fields as well as the performance of current state-of-the-art SR approaches. This review extracts data from four scientific databases and filters with two established high-indexed databases (Scopus and Web of Science). Notably, 25 selected articles fell under two main categories in environment complexity, namely empty space and cluttered. There are four strategies which have been compiled for both empty space and cluttered categories, namely, bio-inspired mechanism, behavior-based mechanism, random strategy mechanism, and hybrid mechanism.

In this paper, a feed ration problem is presented as a mixed integer programming problem. An attempt to find the optimal quantities of Moringa oleifera inclusion into the poultry feed ration was done and the problem was solved using the Bat algorithm and the Cplex solver. The study used findings of previous research to investigate the effects of Moringa oleifera inclusion in poultry feed ration. The results show that the farmer is likely to gain US$0.89 more if Moringa oleifera is included in the feed ration. Results also show superiority of the Bat algorithm in terms of execution time and number of iterations required to find the optimum solution as compared with the results obtained by the Cplex solver. Results revealed that there is a significant economic benefit of Moringa oleifera inclusion into the poultry feed ration.

This study aims to determine whether the improvement of students' mathematical problem solving skills that get the learning of Model-Eliciting Activities is better than students who get regular learning. Method in this research is experiment and research design pretest and postest in experiment and control class. The population in this study were all students of MTs Kota Cimahi. School samples were taken at random, and obtained by MTs Negeri Kota Cimahi. Then the sample is selected two class VIII at random class. The experimental class uses Model-Eliciting Activities, while the control class uses ordinary learning. The hypothesis in this research is the improvement of student solving abilities of MTs students in Cimahi whose learning using Model-Eliciting Activities is better than using ordinary learning. Research data obtained through the instrument of posttest mathematical problem solving ability. The posttest data is processed by normality test, homogeneity test, and two average difference test using SPSS (Statistical Product and Service Solution) software version 16.0 for Windows. The results showed that the improvement of problem solving ability of MTs students in Cimahi whose learning using Model-Eliciting Activities was better than those using ordinary learning.

<p class="JRPMAbstractBodyEnglish">This study aims to examine the effectiveness of Problem Based Learning (PBL) assisted by QR code on students’ mathematical problem solving ability. This experimental research was carried out on students of the Elementary School Teacher Education Study ProgramUniversitas Muria Kudus in the mathematical concept course in the academic year of 2016/2017. The ability to solve mathematical problems is measured by tests. Data analysis techniques used include t-test and proportion test. The results of this study are: 1) the mathematical problem solving ability of students who learn through PBL assisted by QR code is better than the mathematical problem solving ability of students who learn through Direct Instruction learning; 2) the mathematical problem solving ability of students who are taught with PBL assisted by QR code have reached the minimum completeness criteria (MCC) and 3) the proportion of students taught with PBL assisted by QR code that has reached the MCC is better than the proportion of students studying through Direct Instruction learning that have met the minimum completeness criteria (MCC). Thus, the lecturer can develop PBL assisted by QR code to create interesting learning so that students are enthusiastic about the learning, which will have a positive effect on their mathematical problem solving ability.</p>

This research is a quasi-experimental study using one experimental group with the treatment of problem-based learning models combined with writing mathematics and a control group that is only given the treatment of problem-based learning models. Data collection methods consist of tests of mathematical problem solving abilities. Data analysis techniques using two path analysis of variance are not the sam cell. The results showed that the problem-solving ability of students who use problem-based learning models combined with writing mathematics is better than the problem-solving abilities of students who only use problem-based learning models in general or by the category of mathematical early ability. Judging from the early mathematical ability category, high and medium category students showed no significant difference in problem solving abilities while the problem solving ability of high and medium category students was better when compared to the problem solving ability of low category students. Keywords: problem based learning, writing mathematics, problem solving ability, mathematics early ability.
