Data security is a very important compilation using cloud computing; one of the research that is running and using cloud technology as a means of storage is G-Connect. One of the developments made by the G-Connect project is about data security; most of the problems verification of the data sent. In previous studies, Keccak and RSA algorithms have implemented for data verification needs. But after a literature study of other algorithms that can make digital signatures, we found what is meant by an algorithm that is better than RSA in rectangular speeds, namely Digital Signature Algorithm (DSA).DSA is one of the key algorithms used for digital signatures, but because DSA still uses Secure Hash Algorithm (SHA-1) as an algorithm for hashes, DSA rarely used for data security purposes, so Keccak is used instead of the hash algorithm on DSA. Now, Keccak become the standard for the new SHA-3 hash function algorithm. Because of the above problems, the focus of this research is about data verification using Keccak and DSA. The results of the research are proven that Keccak can run on DSA work system, obtained a comparison of execution time process between DSA and RSA where both use Keccak.

The proposed paper, works upon the idea of securing the classified information. This is achieved by using steganography which is an approach to hide classified information into some other file while maintaining its visual aids and secondly is cryptography which works upon textual data and transform it in a way that no one can comprehend it. The proposed method secures the weaker section which is the key in Advance Encryption Standard using hashing technique. The proposed work enhances the level of concealment of information from unauthorized access and for covert information exchange by encrypting the data and hiding it into a multimedia file known as image. The Secure Hash Algorithm 256 generates a hash key of 256 bits which is an unbreakable hashing technique after that the key is used in the process of encrypting the text with Advance Encryption Standard 256 which is an unbreakable encryption technique till this time and a cipher text is obtained. The cipher text is embedded into a target image using Least Significant Bit method which make changes in image that cannot be understand by naked eyes. The change in byte is 0.000002%. It ensures the visual quality of an image remains intact. The distortion or change in the image remains intermittent to human eyes. The major issue concerned for the government and security agencies such as were to exchange highly classified information in a secure and undetectable manner and abide the notion of hacker to comprehend any such information.

Monitoring Information

<p>Dalam sebuah satuan kerja atau institusi pemerintah di Negara Republik Indonesia, terdapat barang-barang yang dibeli atau diperoleh atas beban APBN yang kemudian dapat diidentifikasikan sebagai bagian dari Barang Milik Negara (BMN). BMN tersebut dicatat dalam sebuah aplikasi bernama Sistem Informasi Manajemen dan Akuntansi Barang Milik Negara (SIMAK-BMN). Untuk melakukan monitoring BMN yang telah tercatat di aplikasi tersebut, Kuasa Pengguna Anggaran (KPA) dan tim monitoring seringkali menemui beberapa kesulitan. Hal ini diakibatkan dari keterbatasan aplikasi SIMAK-BMN yang belum sepenuhnya mudah dioperasikan untuk keperluan monitoring. Dengan kondisi seperti itu maka pada makalah ini dibahas pengembangan sistem informasi monitoring BMN terpadu dengan melakukan optimasi terhadap <em>database</em> SIMAK-BMN. Sistem yang dibangun dapat dijalankan oleh tim <em>monitoring</em> BMN secara <em>online</em> menggunakan internet. Selain itu, dikembangkan pula sistem monitoring BMN secara <em>mobile</em> yang dapat diinstall pada perangkat <em>smartphone</em> berbasis Android. Sehingga, dalam pengelolaaanya, petugas tim pencatat dan penginventaris BMN dapat menggunakan <em>smartphone</em> mereka untuk membantu memudahkan pekerjaaan inventarisasi dengan melakukan scanning QR Code dari tiap-tiap BMN. Dengan adanya sistem monitoring BMN yang merupakan optimasi dari <em>database</em> SIMAK-BMN tersebut, diharapkan dapat mempermudah fungsi monitoring BMN dan menjadi kontribusi dalam pengembangan sistem monitoring internal suatu satuan kerja di Republik Indonesia serta mendukung kebijakan-kebijakan pengelolaan BMN.</p><p> </p><p><em><strong>Abstract</strong></em></p><p class="Abstract"><em>In a unit or institution in the government of State of the Republic of Indonesia, there are goods obtained at the expense of the APBN which can be identified as the State Goods (BMN). BMN is recorded in an application called the Management Information System and Accounting for State Goods (SIMAK-BMN). To monitor the BMNs that have been recorded in that application, the Budget User Authority (KPA) and the monitoring team often encounter some difficulties. This is due to the limitations of the SIMAK-BMN application which has not been fully operational for monitoring purposes. With such conditions, this study discusses about the development of integrated BMN monitoring information system by optimizing the SIMAK-BMN database. The built system can be run by the BMN monitoring team using the internet. Moreover, also developed a mobile BMN monitoring system that can be installed on Android-based smartphone devices. Thus, in it’s management, BMN registration team can use their smartphone to scanning QR Code from each item of BMN. With the BMN monitoring system which is the optimization of the SIMAK-BMN database, it is expected to facilitate the BMN monitoring function and become a contribution in developing the internal monitoring system of a work unit in the government of Republic of Indonesia as well as supporting the policies of BMN management.</em></p>

The Relationship

<p><strong><em>Abstarct</em></strong></p><em>Basically ratification of the GPA for Indonesia is the opening of the Indonesian market (market access) to the entrepreneur/companies from other countries, which means allowing entrepreneur/foreign companies to participate in the process of procurement of goods and services (PBJ) government in Indonesia. Similarly, the reverse with Indonesian companies. The existence of market acess makes the relation between national with international law. This is a reason of  authors are interested to know further the relationship conformity with international law related to the readiness of the national Ministry of Public Works and Public Housing (PUPR) when Indonesia ratified the GPA views of the setting methods for selecting/ auction in the construction sector in national legislation. The method used is a normative juridical research and the purpose of research to give recommendation to the Ministry PUPR particularly regarding setting methods for selecting the procurement of construction services when Indonesia ratified the GPA. If viewed from the side PBJ arrangements in the Government in the field of construction, especially regarding the purpose, principles and method of election of, the results showed that Ministry PUPR not ready when Indonesia ratified the GPA, because there is a difference between setting purpose PBJ contained in Perpres No. 54/2010 and its amendments as well as Permen PU No 07/2010 and amendments that more give protection to national companies, while GPA has the open principle. In addition there are differences about the method of selecting good views of the types/forms (nomenclature) and its meaning. So that when Indonesia will ratify the GPA, the Government and the Ministry PUPR in particular need to make adjustments to the "purpose" of regulation PBJ as contained in the Perpres/Permen PU with "purpose" contained in the GPA. Similarly, adjustments to the forms (nomenclature) and the meaning of the audition method.</em>

The issuance of Minister Regulation of Public Works and Public Housing (PUPR) No. 24/ PRT/ M/ 2014 concerning Competency-Based Training Guidelines in the Construction Services Sector is a strong effort by the government to increase the capacity of sustainable construction human resources in order to produce productive and competent human resources. Therefore, the workforce must-have requirements and a series of specific competencies to carry it out effectively and efficiently. Moreover, these competencies must be under the work they will do. The Kirkpatrick Model is used to evaluate the results of training and learning programs and rates against four levels of criteria: reaction, learning, behavior, and results. This research aims to find out what variables affect the effectiveness of competency-based training based on Kirkpatrick's four levels and see whether the competency training activities effectively increase human resources in construction services. A total of 64 questionnaires were then distributed to relevant respondents who attended the competency-based training held in West Sumatera during the 2017-2018 periods. From the results, there are 4 Kirkpatrick level variables that affect the effectiveness of training, namely the level of reaction (21 indicators), learning (6 indicators), behavior (7 indicators), and results (11 indicators). The variable that shows the most effective results is the variable level of learning as much as 47.51%, followed by results (44.56%), learning (47.51%), and behavior (29.27). It can be concluded that  the workforce competency training conducted in West Sumatera from 2017 to 2018 was still less effective.

PurposeA large number of roads have been constructed in the rural areas of India to connect habitations with the nearest major roads. With time, the pavements of these roads have deteriorated and they need some kind of maintenance, although they all do not need maintenance at the same time, as they have all not deteriorated to the same level. Hence, they have to be prioritized for maintenance.Design/methodology/approachIn order to present a scientific methodology for prioritizing pavement maintenance, the factors affecting prioritization and the relative importance of each were identified through an expert survey. Analytic Hierarchy Process (AHP) was used to scientifically establish weight (importance) of each factor based on its relative importance over other factors. The proposed methodology was validated through a case study of 203 low volume rural roads in the state of Himachal Pradesh in India. Ranking of these roads in order of their priority for maintenance was presented as the final result.FindingsThe results show that pavement distresses, traffic volume, type of connectivity and the socioeconomic facilities located along a road are the four major factors to be considered in determining the priority of a road for maintenance.Research limitations/implicationsThe methodology provides a comprehensive, scientific and socially responsible pavement maintenance prioritization method which will automatically select roads for maintenance without any bias.Practical implicationsTimely maintenance of roads will also save budgetary expenditure of restoration/reconstruction, leading to enhancement of road service life. The government will not only save money but also provide timely benefit to the needy population.Social implicationsRoad transportation is the primary mode of inland transportation in rural areas. Timely maintenance of the pavements will be of great help to the socioeconomic development of rural areas.Originality/valueThe proposed methodology lays special emphasis on rural roads which are small in length, but large in number. Instead of random, a scientific method for selection of roads for maintenance will be of great help to the public works department for better management of rural road network.

Purpose Hospital information system (HIS) can be examined as a vital factor for developing the quality of health care and cost managing. There exists abundant literature on HISs, but implementation-based literature of HIS is rare, typically about progressive countries. However, a study that can comprehensively review published articles is scarce. Therefore, this paper aims to examine the systematic and comprehensive study of HIS in developed countries. Together, the benefits and harms relevant to HIS’s different mechanisms have been considered, and the fundamental challenges of them are addressed to design more efficient HIS in the future. Design/methodology/approach HIS has been used globally for numerous years and is now being used in a wide area. HIS is broadly used in clinical settings. Information technology (IT) and information system have been suggested as a required piece to solve the health-care-related issues. Hence, to improve HIS’s ability, this paper conducted a review method concentratating on research related to HIS until 2019. A total of 21 papers were recognized and examined as principal research for the summary. Findings The authors found that HIS can help in reduction of medical mistakes, enhancement doctors’ performance and increase in the quality of the care provided. HIS management can be used to provide better health-care services. Therefore, HIS must be sensible and use clear structures. The authors conclude that, generally, with an increase in awareness, acceptability and the need for HIS worldwide, there will be more strategies and approaches available. Research limitations/implications First, this paper provides an outline of the status of HIS. Second, it identifies some distinct research gaps that could be worth studying. Some flawless work may be removed because of applying some filters to select the original articles. Surveying all the papers on the topic of HIS is impossible, too. Practical implications Design and sustainability of HIS is still a big issue for most developing countries, despite its wide usage in the developed countries. The technology is changing rapidly, so the field should be reviewed regularly. This paper suggests a suitable framework that will guide HIS in the local conditions of developing countries. Social implications The government will be assisted by the suggested solving ways in its performance and design of electronic health-care projects. Originality/value The study brings the viewpoints on the state of HIS mechanisms in developing countries. The paper’s results can offer visions into future research requirements. By providing comparative information and analyzing the current growths in this area, this study will support researchers and professionals to understand the progress in HIS mechanisms better.
