This study aims to evaluate the financial condition of four private banks, namely Bank Mega, Bank JTrust, Bank Danamon, and Bank Panin listed on the Indonesia Stock Exchange during the period 2015 to 2024. The analysis uses the Risk-Based Bank Rating (RBBR) approach with a quantitative method, where the data source is derived from published annual financial statements. The sampling technique was carried out by purposive sampling with the criteria of financial statements available for the last 10 years and the fluctuations in profits in the last three years. The bank's health assessment is carried out through four main aspects. First, the risk profile is measured using non-performing loan (NPL) ratios and liquidity levels through the Loan to Deposit Ratio (LDR). Second, Good Corporate Governance (GCG) is evaluated based on regulatory compliance and transparency reporting. Third, profitability which includes the return on asset ratio (ROA) and net interest margin (Net Interest Margin / NIM). Fourth, the capital aspect is analyzed through the Capital Adequacy Ratio (CAR). The results of the study show that in general, the four banks are in a healthy condition, especially in terms of capital and governance, which reflects the bank's ability to meet the minimum capital requirements and maintain management practices in accordance with banking industry standards. However, significant differences were found in the risk and profitability aspects. Banks that have less than optimal risk management tend to experience an increase in NPLs, while banks that are more efficient in managing operational costs are able to maintain ROA and NIM at a more stable level. In addition, external factors such as global economic conditions, monetary policy, interest rates, and interbank competition also affect financial performance.

The concept of company value is critical for investors as it reflects the potential growth, profitability, and long-term sustainability of a business. Company value is a critical factor that guides investment decisions, as it embodies both tangible and intangible factors that contribute to the firm’s success. The factors that influence company value include Good Corporate Governance (GCG), which refers to the practices that ensure a company’s management is held accountable, transparent, and efficient. It also includes profitability metrics, such as Return on Assets (ROA) and Return on Equity (ROE), which indicate how well a company is performing in generating profits from its assets and equity. This study aimed to analyze how GCG and profitability influence company value, specifically in the infrastructure sector of Indonesia, listed on the Indonesia Stock Exchange (IDX). By using multiple linear regression analysis with data collected from 8 companies between 2020 and 2024, the research uncovered some insightful findings. It was found that the presence of Independent Commissioners, as part of GCG, had a positive and significant effect on company value. This highlights the importance of having independent oversight to ensure that the company operates in the best interests of its shareholders. In contrast, Institutional Ownership had no significant impact on company value, which might suggest that larger institutional investors do not always influence the company’s strategic direction in a way that directly affects value. Additionally, profitability, as measured by ROA and ROE, had significant effects on company value. ROA negatively influenced company value, which may indicate that companies with higher assets do not always perform better in terms of profitability, possibly due to inefficiencies. However, ROE had a positive influence on company value, suggesting that companies that efficiently use equity to generate profits are viewed more favorably by investors.

The need for practical, efficient, and long-lasting makeup is increasing, especially among women who are active in daily activities such as work, college, and social activities. One important element in creating a fresh, expressive, and attractive facial appearance is the condition of the eyelashes. Curled eyelashes can give the impression of larger, fresher, and more vibrant eyes. In makeup practice, there are various ways to curl eyelashes, including using eyelash curlers and mascara. Eyelash curlers are known to provide instant results with a noticeable curling effect, but they are often less durable and have the risk of damaging eyelashes if not used properly. Conversely, using mascara alone is considered more practical and safe, but often less than optimal, especially for individuals with short or straight eyelashes. This study aims to compare the results of eyelash curl and durability between the use of a conventional eyelash curler combined with mascara and the use of mascara alone in morning makeup. The research method used was a quantitative experiment with a One Shoot Case Study design. The research subjects consisted of six female students of the Makeup and Beauty Study Program, Padang State University, who were selected using a purposive sampling technique. Two treatment groups were formed, each receiving a different makeup technique. Seven panelists assessed the curl and durability of the eyelash makeup throughout the day through direct observation and photographic documentation. The results showed that the combination of using an eyelash curler and mascara provided significantly better curl and durability than mascara alone. A t-test confirmed a significant difference in curl (p = 0.001) and durability (p = 0.003). Based on these findings, it can be concluded that the combination of an eyelash curler and mascara is recommended for users who desire maximum, fresh, and long-lasting morning makeup results throughout their daily activities.

This study focuses on the development of an intelligent enemy behavior system in the 2D maze game Dungeon Escape by combining the A* algorithm for pathfinding and a Behavior Tree (BT) structure for decision-making. The main objective is to enhance Non-Playable Character (NPC) intelligence, enabling more adaptive and realistic interactions with players. The A* algorithm is implemented to allow NPCs to pursue players through the shortest and most efficient paths while avoiding obstacles on a grid-based map. Meanwhile, the Behavior Tree framework is designed to manage NPC actions based on dynamic conditions, such as attacking when in close proximity, chasing players within a certain detection radius, and retreating to the original guard position when the player leaves the active zone. The research methodology involves a comprehensive literature review, system design, and implementation using the Unity game engine. Testing procedures consist of both white-box and black-box approaches to evaluate the correctness, functionality, and efficiency of the system. The results indicate that all major game features—including player navigation, combat mechanics, key collection, enemy pathfinding, and user interface interactions—operate smoothly as expected. Furthermore, NPCs exhibit adaptive behavior by dynamically switching between patrolling, chasing, and attacking modes depending on the player’s location and proximity. Performance testing shows that the integrated A* and BT system runs efficiently without significant delays or instability, even in higher-level stages with more complex layouts. The final game prototype includes seven progressively challenging levels, offering players an engaging and dynamic gameplay experience. This study demonstrates that the combination of pathfinding and decision-making algorithms provides an effective solution for designing intelligent NPCs, improving both realism and entertainment value in 2D games. The findings are expected to serve as a useful reference for future research and development in AI-based game design, particularly in the context of Unity game projects.

This study investigates the corrosion inhibition potential of a newly synthesized organic compound, (E)-4-hydroxy-3-(phenylamino)pent-3-en-2-one (LASA3), using computational chemistry approaches. Density Functional Theory (DFT) calculations were performed at the B3LYP/6-31G(d) level of theory with the Gaussian09 software package to evaluate several key quantum chemical parameters. These parameters include total energy, the energies of the highest occupied molecular orbital (EHOMO) and lowest unoccupied molecular orbital (ELUMO), the energy gap (ΔEgap), dipole moment, chemical hardness, softness (σ), and the number of electrons transferred (ΔN). The computational results reveal that LASA3 exhibits a higher EHOMO value and a smaller ΔEgap compared to its precursor molecules, referred to as S.M.1 and S.M.2. A higher EHOMO value suggests that LASA3 has a greater electron-donating ability, which enhances its interaction with the metal surface. Likewise, the reduced ΔEgap indicates greater chemical reactivity and a higher likelihood of forming stable coordination bonds with iron atoms on the carbon steel surface. Electrostatic potential (ESP) map analysis further supports these findings by highlighting the distribution of electron density within the LASA3 molecule. The ESP maps show significant electron-rich regions localized around nitrogen and oxygen atoms, which are potential active sites for adsorption onto the steel surface. This adsorption process plays a crucial role in blocking active corrosion sites and reducing the rate of metal degradation. In conclusion, the theoretical analysis confirms that LASA3 has superior electronic properties for corrosion inhibition compared to its starting materials, S.M.1 and S.M.2. Its ability to donate electrons, favorable dipole characteristics, and strategically located electron-rich sites make it a promising candidate for further experimental evaluation as an efficient corrosion inhibitor for carbon steel applications.  

This study investigates the relationship between fiscal dependence, the effectiveness of locally generated revenue (PAD), and the degree of fiscal decentralization on the Human Development Index (HDI) in four regencies on Madura Island Bangkalan, Sampang, Pamekasan, and Sumenep which have consistently reported the lowest HDI scores in East Java Province. Utilizing panel data from 2011 to 2023, the findings indicate that all regencies remain highly fiscally dependent, with fiscal dependency ratios exceeding 89%. Central government transfers dominate local budget structures, significantly limiting local fiscal autonomy. While PAD effectiveness shows notable achievements such as Pamekasan’s 136.09% realization rate its contribution to total regional revenue remains relatively low. This is reflected in the modest degree of fiscal decentralization, which ranges between 8.56% and 10.72%. Such fiscal limitations hinder the ability of local governments to invest in strategic sectors that directly impact human development, including education, healthcare, and public services. The analysis also reveals that despite effective PAD realization, its nominal value is insufficient to drive substantial improvements in HDI, especially when not supported by strengthened fiscal capacity and local economic mobilization. These findings suggest that PAD effectiveness alone does not translate into better human development outcomes without broader fiscal empowerment. Therefore, a comprehensive fiscal decentralization strategy is required one that not only enhances revenue generation but also improves budgetary governance and optimizes local economic resources. Strengthening local fiscal autonomy is essential for ensuring targeted, efficient, and equitable investment in human development sectors, ultimately fostering sustainable regional development across Madura Island.

In Indonesia, negotiation has become one of the most widely used ADR mechanisms and has developed across various fields, including civil law, labor relations, administrative disputes, and environmental issues. This study aims to analyze negotiation as an ADR forum from two main perspectives. First, a theoretical review that examines the principles of negotiation, its stages, as well as its advantages and limitations compared to other dispute resolution mechanisms. Second, a practical review that elaborates on the implementation of negotiation within the Indonesian legal context through case studies of disputes resolved through negotiation. The research employs a normative-juridical approach to analyze the legal foundations and principles governing negotiation, combined with an empirical review through case data exploration and interviews with legal practitioners. The findings indicate that negotiation offers several advantages, including efficiency in time and cost, procedural flexibility, and the potential for mutually beneficial solutions (win–win solutions). However, this study also identifies challenges such as unequal bargaining positions between parties, limited legal recognition of negotiation outcomes, and the insufficient capacity of negotiators or informal mediators to fully grasp legal aspects. Based on these findings, the study recommends several strategic steps: enhancing legal recognition and protection for negotiation outcomes, strengthening the capacity and competence of negotiators through legal and communication skills training, and expanding the use of negotiation as an initial step in resolving various types of disputes. With stronger legal frameworks and improved human resources, negotiation has the potential to become a more effective, efficient, and sustainable dispute resolution instrument in Indonesia.
