Abstract

The mining industry, a crucial component of the world economy, is inextricably linked to occupational safety hazards and serious health dangers. Effective work safety measures are critical in sustaining worker health, one of which is routine Medical CheckUp (MCU). Mining Company X's MCU installation has been completed, but operating conditions and reporting remain manual, and inspection procedures and job eligibility assessments are inconsistently implemented. As a result, it is vital to digitize the MCU process using the General Medical Check-Up (GeMCU) system. This final project implements the survey and interview method, with testing conducted utilizing System Usability Scale (SUS) and User Acceptance Test (UAT), to assess user usability and satisfaction. The test findings showed that the average score of the System Usability Scale (SUS) test was 75.25 with the "Good" category, and the average score of the User Acceptance Test (UAT) test in each element was 90% for the design aspect, 84% for the user-friendliness aspect, and 82% for the efficiency aspect. Thus, the results of this test can be used as a basis for the feasibility of GeMCU UI/UX design by mining company X.

Abstract

Eco-green concrete emerged as an environmentally friendly solution using waste or leftover materials from various industries. One of them is the replacement of concrete constituent aggregates with materials that do not damage the environment. In this study, Eco Green Concrete innovation was made with a mixture of Submerged Arc Welding (SAW) which is the residual result of the steel welding process, concrete waste, ceramic waste which is substituted for coarse aggregate and rubber waste which is also substituted for fine aggregate with a percentage of 20% SAW waste, 20% concrete waste, 10% ceramic waste, and 8% rubber waste. The purpose of Eco Green Concrete innovation research is to determine the compressive strength of concrete and is expected to affect the estimation of more economical project costs but the quality of concrete used remains quality and environmentally friendly. The research was conducted experimentally by making concrete test objects that were tested for compressive strength at the age of 7, 14, and 28 days, 28-day split tensile strength test and 28-day bending test. Based on the compressive strength test, the results of the 28-day compressive strength test of concrete without innovation were 34.74 Mpa and 33.92 Mpa of innovation concrete. The results of the split tensile strength test of concrete without innovation amounted to 3.87 Mpa and 3.95 Mpa innovation concrete. The results of testing the flexural strength of concrete without innovation amounted to 4.83 Mpa and concrete innovation amounted to 5.22 Mpa. Keywords : concrete, substitution, waste

Abstract

Digital documents have become one of the important components in various aspects of life today, ranging from personal data storage to the exchange of sensitive business information. The threat of Interception, or attempts to unlawfully intercept information, includes situations where unauthorized parties attempt to access or retrieve data without the permission of the owner. Therefore, proper measures are required to secure digital documents from the threat of crime. One of the most effective solutions is by applying cryptography. Several previous studies have been developed by combining AES with other algorithms. One of them is by using cryptographic hash functions such as SHA-256 and SHA-512. Until now SHA is still getting more recent developments, SHA-3 being the latest version of the SHA that offers improvements in security and efficiency. This research aims to evaluate the effectiveness of combining AES-256 with SHA3-512 in protecting digital documents, especially in the context of web applications. Researchers want to provide a better security level solution by using AES-256 with SHA3-512. With this combination, documents are not only encrypted using AES-256 to protect their content, but also using SHA-3 to ensure integrity and authentication. So that this research can help provide alternatives in strengthening the security of digital documents and protecting them from various criminal threats in an increasingly complex digital environment.

Abstract

The operational success of a dam is significantly influenced by slope stability and seepage safety. This study aims to evaluate the slope stability and seepage safety of the Tujuh Bukit 1 Dam, which has been in operation for five years. The research methodology involves the collection of both primary and secondary data, followed by the development of analysis models. The slope stability analysis was conducted under three conditions: static, Operated Based Earthquake (OBE), and Maximum Design Earthquake (MDE). Additionally, a seepage analysis model was developed to assess safety against uplift pressure and piping erosion. The results indicate that slope stability under static, OBE, and MDE conditions meets the required safety criteria. The factors of safety calculated for each scenario demonstrate that the dam slopes are stable and capable of withstanding the specified loads. Similarly, the seepage analysis results show that the Tujuh Bukit 1 Dam is safe against both uplift and piping erosion, with no significant risk of internal erosion or material loss that could compromise the structure. Based on these analysis results, no additional design modifications or reinforcements are required for the Tujuh Bukit 1 Dam. The current design and construction are adequate to ensure the dam's safety and stability under the evaluated conditions. These findings provide confidence in the dam's operational reliability and valuable insights for future monitoring and maintenance strategies. This study underscores the importance of regular safety evaluations for dams and highlights the effectiveness of detailed analytical models in assessing stability and seepage concerns Keywords: Slope Stability, Seepage Safety, Tujuh Bukit 1 Dam

Abstract

The advancement of industry and technology has created opportunities for businesses to turn data into valuable assets that drive growth. Data visualization serves as an effective solution to transform complex data into easily understandable information, thereby accelerating business processes and improving decision-making. The Institute for Policy Development (Poldev) at UGM developed UniTrend, a website that provides real-time public sector data to address the limitations of data access from the government. However, UniTrend's data presentation has yet to consider user-friendliness in reading graphs. This final project aims to address this issue by improving the quality of data visualization in terms of effectiveness and user experience. The resulting design is based on the principles of data-ink ratio and Gestalt principles. A total of nine visualizations from three different designs were tested through low-level tasks and the meCUE questionnaire. The test results showed that data-ink ratio design excelled in three aspects: usefulness by 75%, usability by 67%, overall evaluation by 63%, accuracy by 63%, and preference by 56%. Based on these results, data-ink ratio design demonstrated better overall performance compared to Gestalt principles design. Overall, the application of data-ink ratio and Gestalt principles successfully improved the effectiveness and user satisfaction in accessing information on UniTrend's website data visualizations
