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

Sidoarjo Regency Government has an e-government service called P3M (Pusat Pelayanan Pengaduan Masyarakat) which is implemented to accommodate various public aspirations and complaints. Based on the Citizens Satisfaction Index (IKM) survey in the first semester of 2019, P3M application only worth as 64.7 (not good), besides that, the P3M itself stated that the media that was the favorite of the citizens to submit their complaints was not P3M application, but Facebook. This study aims to describe the acceptance of the citizens of Sidoarjo Regency to P3M applications based on the Unified Theory of Acceptances and Use of Technology (UTAUT) framework that employed performance expectancy, effort expectancy, social influence, trust of the internet, trust of the government, trust of the CSC, facilitating conditions, behavioral intention, and use behavior. Data collection is done by distributing an online questionnaire that contains a total of 25 questions to 100 samples selected based on purposive sampling criteria. The research data was processed using a descriptive statistical approach and results were found the acceptance of the citizens of Sidoarjo Regency toward P3M applications based on the UTAUT model was categorized as high (61.91%). However, there are four variables that have below-average values, i.e. trust of the internet, trust of the government, trust of the CSC, behavioral intention, and use behavior. As a recommendation, these variables need to be optimized for implementation improvement in the future.

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%.
