Published: March 2023

This research focuses on the behavior of political elite taxpayers and their political connections during the COVID-19 pandemic. The research object is the political elite, entrepreneurs, and entrepreneurs who have connections with the political elite in Balikpapan. Using Husserl's transdental phenomenological study to gain an in-depth understanding of the behavior and meaning of tax with tax subjects using the terms "politically elite taxpayers" and "politically connected taxpayers", as a form of perspective on the other side of exploring taxpayer behavior and the meaning of tax by adding a subject to new research other than what has been done by previous researchers (e.g., WP-OP, WP-UMKM, WP-UMK). Meanwhile, it is known that 22 of the 45 political elites in the Balikpapan city legislature have business backgrounds. Even though he later left the management of the company, unless he was still registered as a director for a certain reason along with his existing political connections, it left questions about his independence from his duties as a legislative political elite and his partiality for his business or for his group. Rent-seeking opportunities, budgeting for people's welfare projects, and the distribution of donations for handling COVID-19 are things that they see for themselves to explore compliance, the meaning of taxes, and their behavior in light of the policies that they set in their company. Tax-related policies, this research only focuses on the cost of COVID-19 donations due to indications of large tax aggressiveness and indications of the legitimacy of companies and themselves as political elites with political connections. As a result of the research, based on the reduction of deep meaning found in information from informants, there is suspicion of other political elites prioritizing personal or group interests in project planning and implementation. Political elite taxpayer informants and politically connected taxpayers chose not to follow the rules for implementing the distribution of COVID-19 assistance and chose not to take existing tax facilities to reduce the company's tax burden on humanitarian grounds, and it was difficult to prepare data according to tax rules.

Published: March 2023

Introduction: Infections caused by Strongyloides stercoralis are quite difficult to detect. It can remain silent long before manifesting, which used to occur when patients were under immunosuppressed conditions. This scenario makes the patient’s treatment and recovery hard to deal with. Case Presentation: This paper reports the case of a renal transplant patient who presented disseminated strongyloidiasis infection complicated with neurological manifestations. In order to eliminate Strongyloides stercoralis, the patient initially received oral Ivermectin treatment, and as the infection persisted, parenteral treatment was provided. The patient developed flaccid tetraparesis and increased cerebrospinal fluid protein with albumin- cytological dissociation, initially suggesting the diagnosis of Guillain-Barré syndrome. Conclusions: This clinical report highlights the need for early diagnosis and treatment in cases of immunosuppressed patients with strongyloidiasis infection, as the diagnosis might be neglected.

Authors: Beyzaei Hamid , Ebrahimnezhad Zahra , Dehghani Mehdi
Published: March 2023

Background: Nannorrhops baluchestanica Khodash is a recently introduced shrubby species belonging to the family Arecaceae, distributed in Southeast Iran. Objectives: The antioxidant and antimicrobial potentials of this endemic plant were studied. Methods: The seeds and fruits of N. baluchestanica were collected from a natural population in Shark village, and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity of their hydroethanolic extracts was evaluated to determine potential antioxidant properties. In addition, inhibitory, bactericidal, and fungicidal effects of seed and fruit hydroalcoholic extracts were studied against a variety of pathogens, including three fungal strains (Aspergillus fumigatus, Fusarium oxysporum, and Candida albicans), three Gram-negative (klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli), and three Gram-positive bacterial strains (Bacillus cereus, Staphylococcus epidermidis, and Streptococcus pyogenes) via broth microdilution and streak plate methods. Results: The IC50 values of 26.20 and 33.90 µg.mL-1 were calculated for the fruit and seed extracts, respectively, using vitamin E with IC50 of 10.40 as standard. The MIC, MBC, and MFC values ranged from 128 to 2048 μg.mL-1. The fruit extract inhibited the growth of all microbial strains except for B. cereus and S. epidermidis, while P. aeruginosa and F. oxysporum were the only strains inhibited by the seed extract. In agreement with antioxidant properties, more broad-spectrum antimicrobial effects were observed in the fruit extract. Conclusions: Excellent antioxidant capacities of N. baluchestanica extracts indicate their great potential for treatment or prevention of oxidative stress-related diseases, but only slight effectiveness against infectious agents was observed.

Authors: Fateminasab Zahra Sadat , Shayestehpour Mohammad , Zolfaghari Mohammad Reza
Published: March 2023

Background: Bacillus clausii is being studied as a probiotic candidate. There is insufficient information on the antimicrobial and anticancer effects of B. clausii. Objectives: The present investigation was designed to evaluate the anti-bacterial, anti-adenoviral, and apoptosis-inducing activity of B. clausii cell-free supernatant (CFS). Methods: First, the supernatant of B. clausii was collected after culture for 24 h. Then, its anti-bacterial impact on several genera of bacteria was assessed through the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). Adenovirus 5 (Ad5) was exposed to the CFS under four conditions, including pre-treatment: First infecting cells with CFS and then with the virus; pre-incubation: Incubation of the supernatant and virus for 1.5 hours and then adding to the cells; competition: Infection of cells with the simultaneous mixture of the supernatant and virus, and post-treatment: First infecting cells with the virus and then with CFS. The median tissue culture infectious dose (TCID50) technique determined the virus titer. Real-time PCR was performed to assess the E1A expression. After exposure to the CFS, real-time PCR was utilized to measure the expression of MicroRNA-145, BCL-2, and BAX in HeLa cancer cells. Results: Bacillus clausii supernatant showed an inhibitory effect on Methicillin-resistant Staphylococcus aureus (MRSA), Enterococcus faecalis, S. aureus, Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii. The Ad5 titers were reduced by about 4.61, 4, 3.9, and 3.1 Log10 TCID50/mL in pre-treatment, pre-incubation, competition, and post-treatment tests (CFS dilution: 1/4), respectively. Similar results of the viral titration were seen when experimental and control E1A expression levels were compared. Also, B. clausii supernatant during 48 h exposure to HeLa cells increased the transcript of the BAX, BCL-2, and miR-145 genes to 9.1, 2.3, and 55 folds, respectively, compared to the untreated condition. Conclusions: Bacillus clausii can be a potent antimicrobial and anticancer agent. Further research is required to learn about the spectrum of anti-bacterial, antiviral, and anti-cancerous activities of B. clausii.
Restoring the prestige of the engineering education through a fourth engineering wave in the development of the fundamental scientific knowledge of economy
Authors: Trifonov Stefanov Stefan , Trifonov Stefanov Trifon
Published: March 2023

There is no doubt that in the EU and the USA, engineering education has completely lost its previous prestige. The finest youths have shifted away from aspiring to become engineers towards aspiring to become professional economists and businessmen. It has been forgotten that the enterprises for machines, which are best understood by engineers, are the backbone of every national economy. Furthermore, the lack of human capital capable of managing their economy efficiently, as well as supporting their internal activities, will lead not only to us observing a shift of the finest youths steering away from engineering but also a shift away from a sustainable economic future. This paper presents a new approach that will bring back the previous and welldeserved prestige of the all-important engineering education, a prestige connected to the names of Henry Towne, Frederick Taylor, William Deming, and all the engineers responsible for the three engineering waves in the development of the fundamental scientific knowledge of economy. However, we find ourselves on the brink of a fourth engineering wave in the development of the fundamental scientific knowledge of economy. A wave connected to the Bulgarian-based Institute for Systemic Economic Engineering, which has successfully developed а systemic universal model of the enterprise for machines, a model widely thought to be impossible to develop, but if developed successfully, would bring economic changes equal to the combined magnitude of the economic changes brought by all the previous engineering waves and would form a new type of professional defined by the term “systemic economic engineers”.
Online co-design of a university Work-Based Learning degree programme: lessons learned from comparing cases in United Kingdom and Eswatini
Authors: Smith Christopher , Knowles Graeme , Jones Edwina , Martin Celine , Dlamini Patience , Mahlalela John
Published: March 2023

Greater collaboration is required between universities, industry and society to provide the engineering education that will tackle society’s challenges. Work-based learning (WBL) programmes offer an industry-aligned, academically-informed education to support such socio-economic development. Co-design of such programmes is vital with responses to the COVID-19 pandemic innovating alternative ways to design programmes. Knowles et al (2021) [1] outlined an approach to online programme co-design in the UK university context, framed using Signature Pedagogy and through online conferencing and Miro (online whiteboard). Subsequently, the approach has been utilised to co-design a WBL degree programme in Electrical Engineering in Eswatini, supported by Knowles and other UK and Eswatini colleagues. This paper compares and contrasts cases from UK and Eswatini, and from this address the research question, “What considerations are required to support an effective online process to co-design a work-based learning programme in Engineering?” A collaborative autoethnographic methodology based around field notes, observations and reflections is used to allow exploration across pedagogy, technology, work practices, expectations and challenges. Many aspects of the approach worked well in both cases (for example, effectiveness of Signature Pedagogy, Miro as shared space), whereas differences arose related to limitations in the synchronous use of technologies, and readiness to adopt an outcome-focused approach. Addressing these differences, along with balancing progress against full participation and having clear expectations of participants, are key considerations in online co-design of WBL programmes. Moreover, the approach of Knowles (ibid) has shown to be adaptable with potential for broader adoption.
Collaborative, multidisciplinary, international, and societal relevant: a framework combining challenge-based learning and thesis writing across European universities
Authors: Stahlberg Nadine , Brose Andrea , Diedler Sascha , Kuchta Kerstin
Published: March 2023

ECIU University is an EU-funded European University initiated by a network consisting of 13 universities across Europe. At its core is collaborative learning and research on a European level in close connection with various stakeholders to tackle societal challenges. Learners are engaged in joint project work based on the approach of challenge-based learning (CBL). Here, learners are actively involved in a real and relevant setting. Teams are composed of learners coming from different cultural backgrounds, disciplines, and levels of progress in their individual studies. A challenge within the ECIU framework starts with a “Big Idea” in the area of the UN Sustainable Development Goal 11 “Sustainable cities and communities” that has potential for societal impact. ECIU University offers four types of challenges that differ in length and depth. Within this paper, the first run of an ECIU Strategic Challenge, the most complex challenge type, is introduced. The Strategic Challenge is a six-month format that combines individual working phases while writing on one’s master’s thesis with collaborative working phases while cooperating closely in the team challenge. Hence, it offers a framework in which the progress of challenge and master’s theses are expected to go hand in hand. The concept of how students collaborate in the Strategic Challenge builds up upon the Erasmus+ projects COLIBRI (Collaboration and Innovation for better, personalized, and IT-supported Teaching) and its follow up EPIC (Improving Employability through Internationalisation and Collaboration).
Why change engineering education?: pragmatic perspectives from the humanities and social sciences
Authors: Staley Thomas , Bairaktarova Diana
Published: March 2023

Engineering education in the early 21st century is being transformed in many ways to meet the technological challenges of the future. In particular, the role of the humanities and social science in engineering coursework is under new scrutiny, as educators attempt to strengthen students’ proficiencies in aspects of the profession including interpersonal and intercultural skills, assessment of broader impacts of technical work, and especially ethics. These developments are often framed as responses to the demands of employers and institutions, who view these ‘soft’ skills as increasingly relevant to the work life of technical professionals. In this concept paper, we wish to pursue a somewhat different line of thought: We will examine arguments from the philosophy of science and technology, and from the social sciences, about the value of teaching engineers (as well as other technical professionals) to think through humanistic, social, and cultural lenses. We will review a range of perspectives supporting educational reform along these lines, with a particular focus on work in the recent pragmatic tradition (including Sellars, Mitcham, and others). Having established a range of theoretical defenses for educational reform along these lines in engineering fields, we will then consider the distinctions among them and how these insights might be applied most effectively in engineering curricula. We will conclude by reviewing available evidence for the practical utility of such interventions. We hope, by situating current reforms more firmly within a principled framework of ideas, to provide deeper support for positive change in the education of future engineers.

Published: March 2023

In engineering education, and in work life in general, the past two years have been struggling with Covid-19 pandemic. When considering studying, learning, and working, the teachers and other facilitators have been forced to create innovative methods for online working, aiming to good work efficiency, student engagement, and learning results. Along the development of various online working possibilities, it has been noticed that especially interaction among participants in synchronous online sessions is a challenge. Even if some participants are actively discussing and working in online sessions, some participants remain very silent and indistinguishable. Furthermore, even though the technical tools for online working and learning have developed rapidly during the recent years, technical problems still exist quite often. There are numerous ways for increasing interaction in online sessions, including, for example, asking questions, using camera, utilizing chat or third-party applications like Padlet, and small group discussions in breakout rooms. In this paper, we will present how we utilized Zoom-stamps in two types of workshops. The basic idea in utilizing Zoom-stamps was to increase interaction and communication among participants and help them to further develop ideas created and discussed in the workshop. The lessons learnt from the first type implementations were considered when planning the second type implementations. We will describe the pros and cons of the Zoom-stamp utilization in synchronous online working as well as share our future development ideas.

Future engineers, in addition to technical knowledge, should incorporate in their academic curricula aspects that contribute to make mining a sustainable activity. This will contribute to changing the concept that society has about mining and to be a socially accepted activity. In the mining engineering studies at the Universitat Politècnica de Catalunya (UPC), students have the opportunity to develop cooperation projects together with professors and other staff members. They all collaborate with artisanal miners from different underdeveloped countries, mainly from Latin America, and contribute to making mining more environmentally friendly. Moreover, they have the opportunity to acquire a social sensitivity that can be of great importance during the development of their professional career. This study presents some experiences of undergraduate, master, and doctoral students in cooperation activities in mining. The projects were developed as a collaboration between UPC and universities or NOGs in Latin America. The activities have been carried out in underdeveloped areas where mining is practiced with a high environmental impact and poor use of resources. A survey among the participants in the projects shows the students' favourable perception of this activity.
Tragic Moral Conflict in Endangered Species Recovery
Authors: Bryant Rachel ,   Center for Environmental Philosophy, The University of North Texas
Published: March 2023

Tragic moral conflicts are situations from within which whatever one does—including abstaining from action—will be seriously wrong; even the overall right decision involves violating a moral responsibility. This article offers an account of recovery predicaments, a particular kind of tragic conflict that characterizes the current extinction crisis. Recovery predicaments occur when the human-caused extinction of a species or population cannot be prevented without breaching moral responsibilities to animals by doing violence to or otherwise severely dominating them. Recognizing the harm of acting from within recovery conflicts adds force to appeals for interrogating and dismantling the systems of thinking, valuing, and acting that bring species to the brink of extinction.
The Activities of Truth
Authors: Roniger Scott J. ,   Philosophy Documentation Center
Published: March 2023

In this essay, I discuss the essence of truth. In order to do so, I continue a fecund dialogue between Husserlian phenomenology, as recapitulated by Robert Sokolowski, and Aristotelian metaphysics, as developed by St. Thomas Aquinas. Integrating these phil­osophical approaches enables us to see that beings reveal themselves to us through their activities, both substantial and accidental, and that the active self-disclosure of things can be identified with their intelligibility. It is this objective yet potential intelligibility that we disclose and activate when we think about things truthfully by articulating them in the medium of speech. I therefore define truth as the human person’s syntactic activation of the potential intelligibility of things, and I conclude by showing how these reflections lead us to acknowledge God as the highest and first Truth.

Central bank policy formulation under COVID-19 in Ghana: A fit-for-purpose?
Authors: Ahiadorme Johnson Worlanyo , Adenutsi Deodat E.
Published: March 2023

This paper evaluates the fit-for-purpose of the monetary policy measures implemented by the Bank of Ghana in response to the COVID-19 pandemic. We examine the effectiveness of the BoG’s policy interventions in the context of vector autoregressions augmented with macroeconomic and financial indicators. We demonstrate that the BoG’s monetary policy measures have had nominal, real, and financial effects. The monetary interventions have been successful, as evidenced by the gradual reduction in the sovereign spread, improved financial stability, and increased real economic activity. Our findings suggest that balance sheet actions are less effective and should be moderated in the conduct of monetary policy in jurisdictions without zero lower bound constraints. However, the analysis indicates that in times of crisis, central banks should deploy both standard and non-standard tools to stabilize dysfunctional financial markets and avoid a deflationary spiral. The historical and variance decomposition of the data reveal that monetary policy shocks have historically made the largest contributions to the targeted macro-financial aggregates during the pandemic episodes.
Fundamental character of the risk premium to influence the sustainability of the public debt
Authors: Menguy Séverine
Published: March 2023

Traditionally, conditions of sustainability of the public debt have long been related quite exclusively to fiscal policy and to budgetary parameters. However, the interaction between fiscal and monetary policies regarding the fixation of the interest rate is fundamental. Indeed, a simple analytical modelling shows that if the nominal interest rate increases exponentially with the public debt, because of a default (credit) risk premium, if the confidence of investors is fundamental, conditions of sustainability of the public debt could be much more difficult to comply with. Indeed, if the interest rate is risk-free, values for which the public debt can be sustainable are less constraining if the long-term GDP growth rate is high, or if the long-term risk-free nominal interest rate is small. They are also less constraining if the country decides to turn to a non-negligible primary budget surplus in case of a high public debt. However, if the interest rate exponentially increases with the public debt level, in case of a significant importance of the default (credit) risk premium, these parameters have very limited consequences on sustainable and equilibrium public debt levels. The sustainable public debt that a government should target is then much smaller than in absence of this risk premium.
Simulasi Pengontrolan Kesalahan Transmisi Komunikasi Data dengan Menggunakan Metode Automatic Repeat Request (ARQ)
Authors: Irawan Beny
Published: March 2023

Dalam komunikasi data, pengontrolan kesalahan berkaitan dengan mekanisme untuk mendeteksi dan memperbaiki kesalahan yang terjadi pada pentransmisian frame. Data dikirim sebagai deretan frame, frame tiba sesuai dengan perintah yang sama saat dikirim, dan masing-masing frame yang ditransmisikan mengalami perubahan dan sejumlah variabel penundaan sebelum mencapai receiver (penerima). Kesalahan yang mungkin terjadi adalah hilangnya frame (sehingga frame gagal diterima receiver) dan rusaknya frame (frame diakui telah tiba, namun beberapa bit mengalami kesalahan, sehingga dibuang oleh receiver). peneliti tertarik untuk merancang suatu perangkat lunak yang mampu mensimulasikan proses kerja metode ARQ dalam mengontrol kesalahan pada proses pengiriman data. Metode Selective-Reject ARQ merupakan metode yang paling efisien dari sisi waktu proses, karena metode tersebut mengirimkan beberapa frame sekaligus tanpa harus menunggu balasan dari receiver terlebih dahulu (keunggulan dibandingkan dengan metode Stop-and-Wait ARQ) dan frame yang dikirim ulang hanyalah frame yang rusak / salah (keunggulan dibandingkan dengan metode Go-back-N ARQ). Simulasi metode ARQ di dalam perangkat lunak memberikan gambaran secara umum prosedur yang dilakukan untuk mengontrol kesalahan pada saat pengiriman frame antar perangkat keras.

Published: March 2023

Preboot Execusion Environment Server merupakan layanan jaringan computer yang terintegrasi dengan system operasi linux. Layanan ini merupakan suatu workstation/mesin yang dapat beroperasi tanpa adanya dukungan media penyimpanan (storage/disk) local. Hal ini tentu saja memberi manfaat dalam perkembangan teknologi jaringan computer dalam berbagai aspek. Dalam penerapannya dengan menggunakan perangkat server maupun client yang sama pada distro linux CentOS 7 dan Debian 7 dengan memperhatikan aspek efesiensi seperti waktu akses, jumlah akses dan kecepatan akses untuk meminimalkan penggunaan sumber daya dapat disimpulkan bahwa semakin banyak client maka burst time yang akan digunakan client semakin sedikit. Untuk menanggulangi permasalahan tersebut diterapkan algortima penjadwalan FSCS sehingga kecepatan masing-masing client tetap stabil. Dan hasil diperoleh perbandingan kinerja dari kedua distro linux tersebut bahwa Debian lebih unggul bila melayani client yang sedikit dan CentOS unggul dari segala aspek jika jumlah client semakin banyak.

Authors: Simbolon Ratna Wati , Siallagan Sariadin , Munte Erni Dewi , Barus Berlin
Published: March 2023

Kepuasan mahasiswa adalah tingkat perasaan mahasiswa setelah mendapatkan pelayanan dari suatu kepentingannya. Perasaan tersebut timbul karena mahasiswa membandingkan harapan mengenai jasa yang akan diperoleh dengan kenyataan yang ada. Kepuasan itu sifatnya subjektif dan penilaian tetap tergantung kepada mahasiswa yang memperoleh pelayanan itu. Dengan demikian dibutuhkan rumusan untuk mengukur tingkat kepuasan tersebut lalu di analisa dan di ambil keputusan mengenai tingkat kepuasan yang diperoleh. Dalam penelitian ini teknik pengumpulan data dilakukan dengan kuesioner dari mahasiswa aktif, dimana kuesioner disebar dalam bentuk google formulir disebabkan pembelajaran masih dilakukan secara daring oleh karena pandemi covid-19. Dalam penelitian ini, tujuan yang dilakukan adalah untuk mengetahui tingkat kepuasan mahasiswa terhadap kualitas pelaksanaan proses pembelajaran yang dilakukan oleh perguruan tinggi AMIK Medan Business Polytechnic dengan metode Importance Performance Analysis (IPA), yaitu menggunakan atribut Wujud (Tangibles), Keandalan (realibility), Ketanggapan (responsiveness), Kepastian (Assurance), Empati (Empathy). Hasil yang diperoleh dalam penelitian ini adalah hasil rata-rata tingkat kesesuaian antara kinerja (Performance) dan kepentingan (Importance) sebesar 95% dan itu berarti kriteria tingkat kesesuaian sudah sangat sesuai. Namun oleh karena nilai tingkat kesesuaian masih kurang dari 100% maka masih perlu dilakukan perbaikan terhadap kualitas pelayanan di kampus AMIK Medan Business Polytechnic.

Tempat penyimpanan koleksi dokumen (database) untuk keperluan informasi sudah menjadi lebih mudah, tetapi usaha untuk mendapatkan kembali informasi (dokumen) yang dibutuhkan dan sesuai menjadi sulit karena data yang tersimpan sangat besar, terbagi – bagi dan tidak tersusun. Secara fisik kumpulan dokumen dapat disimpan dalam bentuk disket, hard disk, dan CD-ROM. Secara teknis setiap dokumen yang telah dianalisis subjeknya dan diindeks, disimpan dalam suatu pangkalan data. Di sisi lain, kebutuhan informasi pengguna dianalisis dan direpresentasikan dalam suatu istilah pencarian (search terms). Selanjutnya, representasi dokumen dan pertanyaan pengguna (query) dipadukan dalam suatu proses pencocokan (matching) hingga menemukan dokumen yang relevan. Maka dilakukanlah  teknik probabilitas dengan sistem berbasis kecerdasan buatan yaitu suatu pembelajaran mesin (machine learning) yang diterapkan dalam sistem pencarian dokumen yaitu Information  Retrieval System. Hasil dari sistem ini berupa algoritma genetika yang dapat mensimulasikan  proses evolsi yang berfungsi untuk menciptakan suatu kesatuan solusi (kromosom) untuk memecahkan masalah terutama dalam hal pencarian dokumen  yang diperlukan tanpa harus mendapatkan dolumen – dokumen yang tidak relevan. Algoritma Genetika untuk menentukan kemiripan antar dokumen dalam Information Retrieval System menggunakan nilai Dice Coefficient digunakan untuk pemilihan beberapa kata kunci yang merupakan perwakilan dari keseluruhan dokumen untuk mencari dokumen lain yang mirip dengan melakukan penghematan dalam pencarian karena tidak digunakan seluruh kata kunci. Keunggulan sistem ini, walau begitu banyaknya dokumen yang tersimpan dalam database, pencarian akan mudah dan cepat dan menunjukkan persentasi kemiripan nilai dokumen.

Pencarian (searching) merupakan suatu kegiatan yang sering sekali dilakukan oleh pengguna komputer dengan tujuan untuk mendapatkan suatu informasi. Proses pencarian data sangat bergantung pada cara penyimpanan, media penyimpanan serta kerumitan data pada saat penyimpanan. Salah satu cara penyimpanan data yang di kenal adalah penyimpanan data secara acak (random) dan secara berurutan (sequential). Analisis pencarian alamat data dengan empat teknik menggunakan algoritma yang sesuai dengan teknik masing-masing pada metoda Hashing dengan data teks yang tingkat kerumitan data yang sama, yaitu: Teknik dengan sisa pembagian, Teknik Pemenggalan, Teknik Lipatan, dan Teknik Perkalian. Setelah mengaplikasikan dalam perangkat lunak, maka dapat diambil kesimpulan bahwa proses pencarian lokasi penyimpanan dalam satu dokumen teks dengan menggunakan empat teknik pada metoda Hashing memberikan alamat lokasi penyimpanan dan waktu yang berbeda. Dan hasil yang berbeda pada keempat teknik pada metoda Hashing bertujuan untuk mencegah tubrukan (collision).

Pemanfaatan Teknologi Informasi (TI) pada perguruan tinggi memunculkan berbagai persoalan, salah satunya pemahaman terkait risiko TI tersebut. Universitas XYZ saat ini teridentifikasi memanfaatkan TI untuk layanan di lingkungan kampus akan tetapi belum memiliki dokumen risiko TI. Penelitian ini bertujuan untuk menganalisa dan melakukan perangkingan risiko serta memberikan rekomendasi perbaikan. Penilaian risiko TI menggunakan kerangka kerja COBIT 5 pada domain APO12 (Manage risk) dan EDM03 (Ensure Risk Optimisation), penilaian tingkat risiko menggunakan FMEA, untuk prioritas risiko dan rekomendasi perbaikan menggunakan SAW. Proses manajemen risiko saat ini masih level 1 dengan nilai kapabilitas 1.36 dan kondisi yang diharapkan pada level 2 dengan nilai kapabilitas 2.32 didapatkan gap sebesar 0.96. Domain EDM03 kondisi saat ini pada level 1 dengan nilai kapabilitas 1,19, sedangkan kondisi yang diharapkan pada level 2 dengan nilai kapabilitas 2.11 didapatkan nilai gap 0.91. Hasil identifikasi tingkat risiko pada sub domain APO12 ada 3 proses tingkat risiko pada skala 6, 1 proses pada skala 7 dan 2 proses pada skala 8. Pada sub domain EDM03, terdapat 2 proses tingkat risiko berada pada skala 9 dan 1 proses pada skala 8. Prioritas risiko dan rekomendasi pada sub domain APO12 yaitu APO12.06 (Respond to Risk) paling prioritas dilakukan perbaikan terhadap proses pengelolaannya, sub domain EDM03 prioritas perbaikan pada EDM03.03 (Monitor Risk Management).
