Abstract

One of the problems faced in developing information systems is the calculation of cost estimates, the developer does not have yet a standard for determining costs in information system development. From 25000 information system projects implemented from 2011 until 2015, showed 27-31% stated that the project was successful according to (on budget , on time, satisfy), 17-22% failed (canceled or rejected), and 49-56% are challenging projects (Declared satisfactory but exceeds the budget or deadline, that is due an error use or not use existing estimation methods or models, not re-checking the input or output using Expert Judgment model, or ignorance of which method or model needs to be used in a particular condition. The way that is often used to determine the estimated cost and effort in an information system development project is by using the Expert Judgment Method due to limited time spent on the project, so that more complicated methods like COCOMO II or Use Case Points cannot be used. Based on this problem, the author created a system that helps developer to calculate the estimated cost of developing an information system project that can make it easier to calculate project cost estimates. System development using the Waterfall method. Testing method that used in this research is Basis Path Testing, Boundary Value Analysis, and User Acceptance Testing. Based on the results of testing using User Acceptance Testing, the acceptance value is 84%, which means the system is accepted by user.

Abstract

LPG (Liquified Petroleum Gas) is a petroleum gas that is commonly used as fuel for gas stoves. From year to year the use of LPG has always increased, which is the risk of gas leakage will also increase. So it is necessary to reduce these risks, with create a system that can detect LPG gas leaks. The design of a gas leak detection system must have a high availability value, because when there is a crucial component damage it will cause an inaccurate reading. High availability systems can be achieved by implementing redundancies. In this research, one of the redundancy methods will be implemented, namely Hot Standby Redundancy in the gas leak monitoring system. The gas monitoring system will require gas sensors (MQ-2 and MQ-5) as inputs, Arduino as processors, buzzers and applications as output. While the components that are considered crucial are components or controllers. For the Hot Standby Redundancy redundancy method, it will make a duplicate controller and will always be active to monitor the condition of the main controller. The monitoring process will use I2C serial communication, by means of a backup (master) controller sending requests periodically to determine the condition of the master controller. Based on the tests that have been carried out, the implementation of the Hot Standby Redundancy mechanism in the LPG, downtime gas leak monitoring system both failover and failback is equal to 153.46 ms, with availability of 99.99%.

Abstract

Persons with Social Welfare Problems (PMKS) are social groups that live below the community welfare line and are one of component for determining policies in East Java. The study aim to find out the characteristics of the region in East Java based on the PMKS dataset. The method proposed in this study is clustering with the Self-Organizing Maps algorithm and K-Nearest Neighbors (KNN) missing value imputation. KNN used to overcome the amount of missing value in PMKS dataset. First, missing value is filled using KNN imputation. Furthermore, the clustering done with training in SOM network and the result of cluster is evaluated using Silhouette Coefficient. The best parameters for SOM are learning rate=0.1; neighborhood coefficient=0.2; max epoch=160 and neuron size=2x2. The best parameter for KNN is K=2. K=2 gives an increase in Silhouette Coefficient value of 3.4% compared to clustering without missing value imputation KNN. Using best parameter, the highest Silhouette Coefficient obtained is 0.351 which categorized as weak structure. The shape of the cluster produced is a cluster with a proportion of 1:37. The five attributes with the highest difference between the two clusters were Neglected Elderly, Homeless and Psychotic Homeless, Scavengers, Beggars and Minority Groups.

Abstract

In the past few years, streaming media has been enhanced within the wireless network, which is known as wireless mesh network. There is challenge if streaming connected through WMN, which is caused that streaming application requires broad bandwidth for high speed data within multi-hop media as well, thus produces packet value loss and delay significantly, while the streaming depends on packet loss and delay. That is why the purpose of this research is to figure the effect of streaming on optimized link state routing performance using wireless mesh network technology. As for the parameters used to know streaming quality in the network are; delay, packet loss, throughput and jitter. The testing has been done through some scenarios, which are; connection amongst client - server, streaming testing within 1 Mbps bandwidth, streaming testing within 2 Mbps bandwidth. The testing result of those scenarios deliver the highest throughput value as 928 kbps, value of the smallest delay is produced as 12.6 ms, the lowest jitter value as 0.0000098ms, produces packet loss value as 0.00018%. Based on the testing result, thus video streaming occurs on optimized link state routing performance using wireless mesh network technology shows a very good result.

Abstract

Test case prioritization is a strategy of regression testing. It can reduce the cost of regression testing. Test case prioritization based on lexicographical ordering is considered to be the best technique based on its Average Percentage Fault Detection (APFD). This technique determines test case prioritization based on coverage information of each test case. There have been no studies that implement this technique into a system and research shows that prioritizing test cases based on code coverage is expensive both in terms of time and resources. Because the more number of test cases, the greater size of the code coverage information that have to be read. Therefore, this study developed an application system for test case prioritization based on lexicographical ordering. This system aims to help the process of reading coverage information and determining test case prioritization automatically. So this system is expected to accelerate the determination of test case prioritization. The results of testing phase show that the system has 100% accuracy with reading coverage information in each test case also finding prioritization in less than 8 seconds. This paper will summarize the application system development process. The stages described from the introduction, research methodology, results and discussion, and getting conclusions from the research.
