Abstract

Audit teknologi informasi pada PT XYZ dilakukan untuk mengetahui sejauh mana tingkat kapabilitas teknologi informasi perusahaan dan memberikan rekomendasi guna memperbaiki kinerja teknologi informasi untuk mencapai tujuan bisnis perusahaan. Standar kontrol yang digunakan dalam penelitian ini yaitu Committee of Sponsoring Organizations of the Treadway Commission (COSO) yang terdiri dari komponen Control Environment, Risk Assessment, Control Activities, Information and Communication, dan Monitoring. Tujuan penelitian ini adalah untuk mengevaluasi apakah sistem sudah dilengkapi dengan kontrol yang dijalankan dengan baik dan benar. Dari hasil penelitian, capability level pada PT XYZ dalam layanan teknologi informasi berada pada level 4 (Predictable Process) dengan nilai 4,17. Hasil ini menunjukkan bahwa proses atau kegiatan teknologi informasi pada PT XYZ telah dilakukan dengan konsisten dan memiliki batasan yang ditentukan oleh perusahaan. Nilai expected level yang ingin dicapai berada pada level 5 (Optimizing Process). Perbedaan hasil level ini terjadi karena bagian IT PT XYZ belum melakukan pengawasan dan evaluasi lebih lanjut untuk menunjang kegiatan perusahaan.

Abstract

PT XYZ is an agri-food company that has used the information technology for its company's operations. Information technology management at PT XYZ requires an audit to determine the level of information technology capability on PT XYZ and it provides a recommendations for business process improvements to achieve the business objectives of the company. Since this audit is intended to assess the managerial and technical aspect of information technology, audit of PT XYZ is conducted by applying COBIT 5 framework. Procedure of COBIT 5 consists of audit plans, audit preparation phase, the implementation phase of the audit, and audit reporting stage. This audit measures the capability level of information technology management at the sub-domain Manage Strategy (APO02) Manage Enterprise Architecture (APO03) Manage Relationships (APO08) Manage Suppliers (APO10) Manage Requirements Definition (BAI02) Identification Solutions Manage and Build (BAI03), and Manage Knowledge (BAI08). Based on evaluation using COBIT 5, PT XYZ is in the level 2.6 out of 5. Due to the rounding index value, the measurement results are at level 3 (Established Process) while the company's expectation level is at level 5. The level difference occurs because PT XYZ has not conducted a review, evaluation, and report of the settlement. Therefore, companies need to improve information technology management in achieving the company's business goals.

Abstract

PT. XYZ needs information technology to carry out all activities in presenting the latest news. Audit of information technology services is needed to determine the extent of information technology services in PT. XYZ. This study uses Information Technology Infrastructure Library (ITIL) framework to audit domain service operation of PT. XYZ. The focus of this research is on the domain service operation. Data from this study were obtained based on the results of interviews, observations and questionnaires. The results of the study found that the level of maturity of PT. XYZ in information technology services in the service operation domain of respondents was 3,1 (Defined) and the finding were worth 2 (Managed). This result is different from the expected because IT Lampung haven’t met the SOP criteria standards, especially in management incident reports and resolved. IT division also haven’t conducted user’s statisfaction survey about the IT service provided.

Abstract

KKN is an intracurricular activity that provides learning and work experience to students in community development activities. The Implementation Board of the Real Work Program (BP-KKN) of the University of Lampung made the information system an important component in the implementation of KKN. BP-KKN's success in carrying out its duties depends on the extent to which the KKN information system management has been implemented. The use of the KKN information system raises various risks that can interfere with the implementation of KKN and cause losses both non-material and material to BP-KKN. BP-KKN needs to apply risk management to reduce the risks that arise, so that the problems caused do not result in the use of KKN information systems being hampered. The method used is NIST 800-30 which is an information system risk management framework with three stages, namely risk assessment, risk mitigation, and risk evaluation. KKN has 9 risks that can interfere with the sustainability of the information system. The final result of the KKN information system risk management is in the form of recommendations given to reduce the risk that will occur in the information system.

Abstract

Telecommunication industries are experiencing substantial problems related to the migration of customers due to a large number of competing companies, dynamic circumstances, as well as the presence of many innovative and attractive offerings. The situation has resulted in a high level of customer migration, affecting a decrement toward the company revenue. Regarding that condition, the customer churn is one well-know approach that can help in increasing the company's revenue and reputation. As to predict the reason behind the migration of customer, this study proposed a data mining classification technique by applying the C4.5 algorithm. Patterns generated by the model were implemented using 10-fold cross-validation, resulting in a model with an accuracy rate of 87%, precision 87.5%, and a recall of 97%. Based on the good performance quality of the model, it can be stated that the C4.5 algorithm succeeded to discover several causes from the migration of telecommunication users, in which price holds the top place as the primary reason

Abstract

Fakultas MIPA merupakan salah satu fakultas di Universitas Lampung yang menjadi pusat perkembangan ilmu pengetahuan dasar. Namun, minat masyarakat terhadap jurusan-jurusan di Fakultas MIPA semakin berkurang setiap tahunnya. Oleh karena itu, dibutuhkan suatu media yang dapat memperkenalkan Fakultas MIPA dan memberikan informasi setiap jurusan kepada calon mahasiswa dan masyarakat pada umumnya. Virtual tour guide merupakan aplikasi yang menggabungkan teknologi virtual tour dengan teknologi virtual reality. Aplikasi ini menampilkan informasi berupa keunggulan yang dimiliki oleh Fakultas MIPA. Pengguna dapat berinteraksi langsung dengan lingkungan serta gedung yang ada di Fakultas MIPA walaupun dalam bentuk 3 dimensi. Selain itu, pengguna juga diberikan akses penuh untuk mengatur informasi yang ingin ditampilkan. Aplikasi yang dibangun menggunakan metode Multimedia Development Life Cycle (MDLC) ini dapat dioperasikan di smarphone android. Berdasarkan hasil pengujian, aplikasi ini membantu masyarakat untuk lebih mengenal lebih detail tentang jurusan di Fakultas MIPA. Namun, aplikasi ini hanya dapat berjalan dengan baik pada smartphone dengan spesifikasi hardware yang tinggi.

Abstract

Diabetes Mellitus (DM) is a chronic disease characterized by the body's inability to metabolize carbohydrates, fats, and proteins, resulting in increased blood sugar (hyperglycemia) due to low insulin levels. Diabetes is due to a combination of heredity (genetics) and unhealthy lifestyles. Hemoglobin A1c is a blood test used to diagnose and manage diabetes patients when measuring blood sugar levels. This study aims to analyze predictive models for the classification of people with diabetes using R Shiny and evaluate the results of the support vector machine method's classification performance. There are many ways to diagnose diabetes, and the support vector machine is one of the machine learning algorithms used in this study's classification case (SVM). This study uses data from Diabetes 130-US Hospital For Years 1999-2008, which was sourced from the UCI Machine Learning Repository and consists of 34 variables and 84900 records, with dataset distribution and testing techniques using the 10-fold cross-validation method and three kernels in modeling using SVM, namely linear, Gaussian, and polynomial. The results obtained are a simple predictive model analysis system for classifying people with diabetes with shiny, making it easier for users to find out the prediction results and obtain the highest accuracy result, which is 82.76 percent of the gaussian kernel.
