Abstract

The National Unity and Political Unit (Kesbangpol) of Batu City is a service that engages in politics to improve national security and unity in Batu City and has several external services, namely survey and apprenticeship services, mass organization registration services and information services on political development and intelligence information. In carrying out its activities this service uses a manual method for survey permit and apprenticeship registration services. Applicants (students and students) who will conduct surveys and internships in various Regional Organizations (OPD) or Dinas in Kota Batu must visit the office of the National Unity and Political Office of Kota Batu by bringing several requirements to obtain a registration permit. Constraints and problems faced are when a signature is needed from the head of office but the head of office is out of town or not in the room and the applicant who lives far from Kesbangpol Batu City is having trouble registering by visiting the office and risk losing file. To overcome these problems, a survey permit and apprenticeship permit information system is needed. System analysis and design is carried out using an object oriented approach. Evaluation in research uses consistency analysis, decision table and prototype testing. This research produces a web-based information system design that allows applicants to register via the web, the Head of Office can verify registration permits and the parties concerned can carry out their duties through the system. The results of the evaluation of the information system design show consistency between the requirements with the design and testing of the prototype that produces input for design improvement.

Abstract

Heterogeneous communication protocols in internet of things lead to problems of interoperability, in particular the syntactical interoperability. In previous research has developed semantic IoT web service that can receive data from the sensors node via HTTP. However, the use of HTTP is not enough to receive data from the sensors node with diverse communication protocols. These problems are also compounded by the existence of a sensor node has limited or resource-constrained. One of the solutions of these problems is the addition of communication protocol on semantic IoT web service to connect with a resource-constrained sensor node. Constrained Application Protocol (CoAP) is a communications protocol that is capable of handling the problems of resource-constrained. CoAP designed to use minimal resources, making it suitable to be implemented on the environment the IoT has limitations. Therefore, in this study will be added CoAP as the protocol communications on semantic IoT web service. In terms of functional test results indicate semantic IoT web service is able to accept JSON-shaped data, images and video via communication protocols CoAP. The addition of the CoAP on semantic IoT web service is also capable of handling the problems of interoperability, in particular the syntactical interoperability by providing communication protocol via HTTP and CoAP.

Abstract

PRAKERIN (Industrial Work Practice) is a method to improve vocational high school (VHS) student skills before entering real world of working. SMK PGRI 3 Malang is one of the largest VHS in Malang City. PRAKERIN management in this school managed by Industrial Cooperation Division (BKI). There are four phases to manage PRAKERIN, those are placement, monitoring, judgment, and evaluation. At placement phase, it need a lot of time to plot a student in company. This is because student can't find a company independently, company needs always changing, and BKI have to re-record company needs manually. At monitoring phase, student don't have any back up data for their journal and PRAKERIN report still need a lot of time. At judgment phase, score recapitulation is still doing manually. The system development take case in SMK PGRI 3 Malang with placement, monitoring, and judgment as the boundaries. System development begin with requirements engineering till testing phase.. There are 80 functional requirements in requirements engineering phase. Laravel is used to implement the system. Unit test resulting 100% valid from 17 test cases and validation test resulting 100% from 145 test cases. User acceptance testing show that system is approved by the users. For further research there are some suggestion. First, adding automatic placement feature using artificial intelligence algorithm, automatic document numbering, and sending notification through another media. In addition, adding some criteria in user acceptance testing will be good to assure the quality of software developed..

Abstract

Partisipasi masyarakat dalam dunia politik merupakan kegiatan sukarela dari warga masyarakat dimana mereka mengambil bagian dalam proses pemilihan pemimpin ataupun wakilnya. Didapatkan fakta bahwa tingkat kepercayaan publik terhadap DPR sangat rendah dimana sebanyak 82 persen responden tidak percaya pada DPR baik dari kalangan kelas bawah maupun kelas atas, kandidat calon legislatif juga tidak optimal karena lebih kepada sosialisasi sosok atau figur daripada ideologi dan program kerja mereka. Pada era digital seperti pada saat ini internet dijadikan salah satu media yang berperan besar dalam proses kampanye untuk menjaring massa dalam pemilu. Hal tersebut menjadi trend tersendiri dalam pelaksanaan pemilu. Selain itu proses penyampaian gagasan dari para calon anggota legislatif ke masyarakat dapat dilakukan dengan baik melalui media web maupun media sosial termasuk facebook. Untuk mengatasi permasalahan tersebut penulis melakukan pembangunan Portal Informasi Political References yang memuat visi dan misi, program kerja, riwayat pendidikan, pekerjaan, organisasi ,rekam jejak digital serta pendapat masyarakat dengan memberikan rate, upvote dan komentar pada setiap halaman profil calon anggota legislatif sehingga dapat lebih diketahui track record nya dengan menerapkan metode prototyping serta menggunakan framework Laravel dan Semantic UI. Dari hasil penelitian didapatkan nilai usabilitas sebesar 81,5 yang menunjukkan bahwa sistem sudah masuk predikat B untuk tingkat Grade Scale dan Acceptable untuk tingkat Acceptability Ranges sehingga sudah dapat diterima dengan baik oleh pengguna dan mudah untuk digunakan. Community participation in politics is a voluntary activity of community members where they take part in the process of selecting leaders or representatives. It was found that the level of public trust in the DPR was very low, where as many as 82 percent of respondents did not believe in the DPR both from the lower classes and the upper class society, candidates were not optimal because they were more concerned with socializing their figures than their ideology and work programs. In the digital era, as at this time the internet was used as one of the media that played a major role in the campaign process to capture the masses in elections. This has become a distinct trend in the elections. In addition, the process of delivery ideas from legislative candidates to the community can be done well through web and social media including Facebook. To overcome this problem the author constructs the Political References Information Portal which contains the vision and mission, work program, history of education, employment, organization, digital track record and community opinion by giving rates, upvotes and comments on each profile page of legislative candidates so more track record can be known, by applying the prototyping method using Laravel and Semantic UI framework. From the results of the study, it was found that the usability value was 81.5 which indicates that the system has got predicate B for the Grade Scale and Acceptable level for the Acceptability Ranges so its indicates that the system can be well received by the user and easy to use

Abstract

Maintainability is defined as the ease of modifying a system or component of software. Previously there were studies from Kumar and Dhanda in 2015 namely "Maintainability Measurement Model for Object Oriented Design" which states that the results of maintainability values ​​can be known based on flexibility and extendibility in the class diagram. The study explained that the calculation is quite time-consuming because it has to do the calculation process of the 4 metrics of Quality Model for Object-Oriented Design (QMOOD). Therefore this research is intended to build a tool for measuring maintainability at the stage of software design automatically by implementing the calculations found in the Kumar and Dhanda research. Development is done using the Waterfall method. The tools are desktop-based by entering the XML class diagram file in a standard simple format from the visual paradigm application to determine the value of maintainability. These tools have a time based efficiency of 0.67 tasks/second, which is faster than manual measurement which has a time based efficiency of 0.0082 tasks/second. Besides that, it has overall relative efficiency or the success of completing tasks by 100%.
