Mine disposal materials such as tailings, overburden, and waste rocks are critical components in mining operations that require comprehensive understanding of their geotechnical properties to ensure stability and safety of storage facilities. This literature review aims to analyze the role of particle gradation and mineralogical composition in determining shear strength and compressibility of mine disposal materials, with particular focus on nickel mining. A sistematic literature review method was employed by analyzing 30 scientific publications from 2019-2025 obtained from various academic databases. The review findings indicate that particle size distribution (gradation) has significant influence on shear strength and compressibility, where materials with coarser gradation and higher coefficient of uniformity (Cu) exhibit greater shear strength and lower compressibility. Mineralogy, particularly clay mineral content, increases cohesion and microporosity but also increases compressibility under loose conditions. Studies on nickel mine waste demonstrate that ferronickel slag possesses favorable drainage characteristics suitable for rockfill material, while tailings require strict gradation control. In conclusion, comprehensive characterization integrating gradation parameters (Cu, Cc, D50) with mineralogical analysis (XRD, XRF) is essential for predicting mechanical behavior of mine disposal materials and designing safe storage facilities.

The number of corruption cases in Indonesia continues to increase. The termination of the investigation of alleged corruption at the Aceh Truth and Reconciliation Commission by the Banda Aceh City Resort Police based on a Memorandum of Understanding between the Government Internal Supervision Apparatus and Law Enforcement Apparatus raises problems because it is contrary to the Law on the Eradication of Corruption Crimes which emphasizes that the return of state losses does not erase the crime. This inconsistency raises questions about the validity of stopping corruption cases through the Memorandum of Understanding. This study aims to assess the validity of the Memorandum of Understanding between the Government Internal Supervision Apparatus and the Law Enforcement Apparatus as the basis for stopping corruption cases, as well as to outline the legal process that should be taken by the Banda Aceh City Resort Police. This research uses a normative juridical method with a legislative, case, and conceptual approach, based on secondary data from various legal materials. The analysis was carried out in an analytical descriptive manner. The results of the study show that the Memorandum of Understanding between the Government Internal Supervision Apparatus and the Law Enforcement Apparatus cannot be the basis for the termination of corruption cases at the Aceh Truth and Reconciliation Commission because it is only coordinated, not a source of criminal law. The note is only suitable for use to follow up on reports through audits. In addition, the Banda Aceh City Resort Police should continue the case to the investigation stage because the elements of corruption, evidence, as well as elements of mens rea and actus reus have been fulfilled without any justification or excuse. It is suggested that the memorandum of understanding can only be a coordinating guideline, not a basis for stopping corruption cases. Any report must still be processed, and the Banda Aceh City Resort Police are obliged to continue the investigation even though the state losses have been returned.

The rapid advancement of digital technology has significantly influenced students’ learning behavior while gradually reducing their interest in local cultural education, including the study of the Javanese script. This phenomenon is evident at SDIP Haji Muhammad Subandi, where most students still struggle to recognize, read, and understand Javanese characters due to the limited use of engaging and interactive learning media. To address this issue, a 2D educational game was developed as an innovative, contextual, and enjoyable learning medium that integrates cultural elements into an interactive digital learning experience. The design and development process employed the Multimedia Development Life Cycle (MDLC) method, which consists of six stages: concept, design, material collecting, assembly, testing, and distribution. The game was built using Unity software to produce dynamic visuals, responsive controls, and supporting audio elements that enhance the immersive quality of gameplay. The educational game enables students to learn Javanese script through interactive play activities, including letter recognition, pronunciation practice, and quiz-based challenges. Each component was designed to strengthen cognitive understanding while increasing students’ intrinsic motivation to learn. Expert validation results indicated that the game met the “highly feasible” criteria as a learning medium, while user testing showed notable improvements in motivation, engagement, and learning enjoyment. Overall, this educational game not only enhances learning effectiveness but also contributes to the preservation and revitalization of the Javanese script as part of Indonesia’s cultural heritage in the digital era. Therefore, this game-based learning approach serves as an adaptive and culturally grounded educational innovation for primary-level students
