Abstract

The role of stakeholders in government agencies in making decisions to disclose dataset in the public domain is very important and fully central. In Indonesia, government institutions are primary data providers and have the authority to determine which types of datasets may be disclosed to the public. Nevertheless, the decision-making process to open datasets carried out by government institutions is cumbersome and faces several challenges. At the same time, stakeholders can have different perspective on data disclosure, and therefore there can be pros and cons between them. Some of the causes of potential disputes in this decision making are because of several factors, such as differences in goal settings, interests, and requirements among stakeholders. The purpose of this study is to map the role of stakeholders in making data disclosure decisions. In order to map roles, this research involves several stakeholders from internal government institutions such as decision-makers, data analysts, and data evangelists. The results of this mapping indicate that each stakeholder proposes a unique blend of expertise, legitimacy, experience, risk-averse culture, as well as potential usefulness in making decisions to disclose data to the public domain. Based on the results of a case study using a semi-structured interview approach, it can be concluded that the decision-maker tends to consider the benefits and risks efficiency factors. Data analysts have an important role in weighing the benefits and risks. Meanwhile, data evangelists also play an essential role in in-depth technical analysis aspects to make stronger evidence-based or reference-based decision-making. This research contributes to providing the level of stakeholder involvement in the form of mapping roles and interests to change the current state of the stakeholder position to the desired state in the government strategic plan.

Abstract

From remote control and surveillance to energy and health monitoring, IoT devices provide cutting-edge services to improve our lives. Nevertheless, IoT technologies raise complicated, innovative privacy-related issues that might limit their widespread adoption. Due to the passive nature of many IoT devices, it may be challenging for users to understand that their personal information is being gathered. Therefore, this paper aims to examine the Privacy by Design IoT application idea. We adapted the seven principles of Ann Cavoukian's Privacy by Design, which were first developed. In this study's qualitative descriptive methodology with interview sections are used. The results indicate that the majority of IoT users agree with and have high expectations for the Privacy by Design concept to be one of the remedies to the imbalance between concerns about the risks and benefits of using IoT.

Abstract

Cloud-based services are service system mechanisms used by companies or organizations in conducting computerized and integrated transactions in a computer network. A service system must of course be balanced with a level of security. This is used to anticipate cyber crimes that have the potential to occur. Cloud-based services themselves are usually offered by a Cloud Service Provider (CSP). CSPs are generally configured so that they are accessible on the public internet for their services. Companies that prioritize data security want a system that is safe from a series of cyber crimes. Private cloud computing scheme is a solution that can be implemented as an alternative. The problem that occurs is the possibility of MITC (Man in the Cloud) attacks that infiltrate and manipulate identities so that they are detected as fake insider threats on cloud systems. This thesis aims to carry out threat analysis with the Man in the Cloud attack technique on private cloud computing services based on a study of the ISO 27032 standard. Reports and documentation of the results of the analysis are expected to become recommendations for the cybersecurity investigation and management process related to threats to cloud services with private schemes cloud computing.

Abstract

In April 2011, the term Industry 4.0 was introduced at the Hannover Fair. PT Yamaha Indonesia was an early adopter, implementing it in their piano manufacturing process. To achieve production targets, it is necessary to monitor the production series, including the assembly of piano components into a complete unit. SAP, a software platform, is used to improve efficiency, with one of its modules being K-STAFF, which has four derivative applications: K-Master, K-Ticket, K-Score, and K-Tiptop. However, the current production process is monitored through scanning input using a SAP derivative application, which is not visualized in the production area, leading to failed targets. To address this issue, a system is required to visualize input scan results to enable direct monitoring of the production process and achieve production targets. As a result, PT Yamaha Indonesia developed the Ratio Set Assy Grand Piano system using the SCRUM method. This system includes an MIS that monitors the ratio set of piano, visualized with Apache E-Charts, manages planning, and identifies priority spare parts in real-time. This research contributes to the development of a more efficient and effective production process

Abstract

Occupational safety and health hold significant importance for both agencies and individuals alike. A crucial aspect of assessing driver readiness involves examining their physical well-being. Truck drivers who possess unhealthy physical conditions face a four-fold higher risk of work accidents compared to those with sound physical health. PT. Toyota Motor Manufacturing Indonesia (TMMIN), being a manufacturing company, must prioritize occupational safety and health, particularly within the logistics domain. Presently, some logistics partners collaborating with TMMIN adhere to their own standards when conducting checks, relying on paper records for documenting the results. Unfortunately, this approach hinders proper archiving of inspection records and fails to establish a direct link with logistics partner customers in cases involving drivers with health issues. Hence, PT. Toyota Motor Manufacturing Indonesia is dedicated to enhancing the quality of driver health checks through logistics partners by implementing an integrated recording system called the Logistics Driver Tenko System Application (ORIENT). The development of ORIENT is based on the Scrum framework. This research aims to offer insights into the direct implementation of the Scrum method in project development.

Abstract

This research focuses on sentiment analysis in the marketplace reviews in Google Play Store, a platform for downloading Android applications and providing reviews. Sentiment analysis is essential for understanding user responses to applications, particularly in the app marketplace. In this study, two machine learning algorithms, Naïve Bayes and Logistic Regression, are employed to classify user reviews. The application rating is used as a reference to determine the sentiment of each comment. The dataset is divided into two conditions: using 2 labels (positive & negative) and 3 labels (positive, neutral, & negative). The test results indicate that the highest performance is achieved by classifying with Logistic Regression on the Shopee dataset with 2 labels. The accuracy reaches 84.58%, precision reaches 84.66%, and recall reaches 84.63%. Additionally, the fastest processing time occurs when testing the Lazada 2-label dataset with Naïve Bayes, taking only 0.038 seconds. Overall, the research suggests that datasets with 2 labels tend to yield higher accuracy compared to datasets with 3 labels.

Abstract

Analisis malware membutuhkan keterampilan khusus untuk melakukan pendeteksian dan memahami cara kerja dari malware tersebut. Program berbahaya atau malware menjadi sebuah ancaman atau masalah yang sulit bagi para peneliti, tidak ada platform komputasi atau lingkungan yang kebal terhadap ancaman tersebut. Kompleksitas yang meningkat membuat para peneliti harus bekerja keras dan membutuhkan waktu untuk memahami cara kerja malware. Terdapat dua teknik dasar yang sering digunakan untuk melakukan analisis malware yaitu statis dan dinamis analisis, dan penelitian malware yang dilakukan selama ini masih berfokus pada analisis perilaku yang keberhasilan metode tersebut tergantung pada model malware. Penggunaan teknik signature based sangat tergantung pada perilaku malware yang dianalisis, analisis menjadi sulit ketika ditemukan malware baru yang menggunakan suatu teknik baru untuk menyulitkan sistem analisis. Berdasarkan uraian fakta yang disampaikan, dianggap perlu dibangun sebuah ontologi dalam melakukan analisis terhadap malware sehingga dapat digunakan sebagai pengemabangan, pemetaan pengetahuan serta mengindetifikasi tren, dan pola dalam melakukan analisis malware. Pada penelitian ini metode yang diusulkan adalah pengembangan dari metode Malware Analysis Body of Knowledge, dimana metode ini bekerja pada domain tertentu untuk memetakan karakteristik dan mengklasifikasi jenis malware yang akan dibahas. Pada penelitian ini berfokus kepada ontologi sebagai knowledge base dan pembahasannya lebih kepada memetakan karakteristik dan pengklasifikasian jenis malware.
