This research employs a Systematic Literature Review (SLR) approach to analyze the application of the simplex method as a tool for solving real-world optimization problems. Mathematics education plays a crucial role in developing critical thinking and achieving accurate results. Linear programming, with its highly effective simplex method, is a branch of mathematics proven to solve various optimization challenges such as cost minimization, profit maximization, distribution, and scheduling. In practice, the simplex method is an alternative algorithm that systematically searches for the optimal solution to problems by moving from one feasible solution to another until the best result is achieved. This study identifies, examines, evaluates, and interprets relevant studies on the simplex method's application in real-world contexts. Our review of 20 journals reveals that the simplex method is highly effective in solving a wide range of optimization problems, from large-scale industries to Micro, Small, and Medium Enterprises (MSMEs). Examples of its application include optimizing fish feed costs at PT. Indojaya Agrinusa, maximizing profits for Seblak MSMEs, determining optimal sales quantities for areca nuts, and optimizing the production of tofu and pottery crafts, among others. The simplex method's ability to consider various limiting factors has proven to be extremely helpful.

Linear programming is a crucial operations research method for optimization problems in various fields like manufacturing and logistics, but it is often hindered by the absence of a basic feasible solution due to artificial variables. The Big M method addresses this by adding artificial variables and a large penalty, allowing the discovery of a valid initial solution without altering the constraint structure. This research employs a Systematic Literature Review (SLR) to examine the implementation of the Big M method in Indonesia from 2015-2025, analyzing journals and proceedings related to linear programming optimization. The review findings indicate that this method is highly effective and flexible for diverse cases such as production, animal feed, and scheduling, capable of handling artificial constraints and optimizing profit or cost. Although efficient, the Big M method has drawbacks, including computational complexity and dependence on the precise selection of the M value, which can affect result accuracy. Overall, the Big M Method remains relevant and important for real-world optimization problems requiring systematic constraint handling.

This study aims to systematically review the application of sensitivity analysis in operational decision-making based on linear programming. The research method used is a Systematic Literature Review (SLR), analyzing scientific articles published between 2018 and 2024 from databases such as Scopus, ScienceDirect, SpringerLink, and Google Scholar. The review focuses on how sensitivity analysis is employed to evaluate the stability of linear programming solutions in the face of parameter changes, such as objective function coefficients, constraint bounds, and resource availability. The results indicate that local sensitivity analysis approaches are the most commonly used due to their simplicity and ease of interpretation. However, they fall short in capturing parameter interactions and complex uncertainty. Therefore, recent studies have started to explore global sensitivity methods, such as Morris and Sobol techniques, as well as geometric visualization approaches to provide a more holistic understanding. This study recommends integrating both local and global approaches and utilizing computational tools to enhance the robustness of operational decisions. The findings are expected to serve as a reference for more adaptive, efficient, and resilient decision-making under uncertainty.

This study examines the transfer of trademark rights as a means of debt settlement in corporate bankruptcy proceedings, using the bankruptcy case of PT Nyonya Meneer as a case study. The main issue addressed is how trademarks, as intangible intellectual property with high economic value, can be used as debt settlement assets during bankruptcy. This research employs a normative legal method with statutory and conceptual approaches, supported by a review of relevant court decisions. The analysis focuses on the relationship between the provisions of Law No. 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligations and Law No. 20 of 2016 on Trademarks. Trademarks may be transferred or sold to fulfill the debtor's obligations. Theoretical foundations include the Creditors’ Bargain Theory (Thomas H. Jackson) and the principle of wealth maximization (Richard A. Posner), emphasizing collective settlement and asset value optimization. The findings reveal that trademark transfer in bankruptcy is not explicitly regulated, creating a legal gap that affects the effectiveness of debt settlement and the protection of creditors’ rights. In the PT Nyonya Meneer case, the trademark despite its potential as a debt settlement instrument was not utilized optimally. Therefore, direct transfer of trademarks to creditors as a form of debt payment can be seen as an alternative solution, provided it is conducted under the principles of justice, legal certainty, and efficiency. This study recommends further regulation on the management and transfer of intellectual property within the bankruptcy regime to address the challenges of modern business practices.

This study aims to analyze the influence of Foreign Direct Investment (FDI), Domestic Investment (DI), and Labor Force Participation Rate (LFPR) on the growth of Gross Regional Domestic Product (GRDP) in Bali Province. This research employs a quantitative approach using secondary time series data on an quartal basis from 2015 to 2022, obtained from the Central Statistics Agency (BPS) and other relevant institutions.

The production process is a crucial aspect in ink formulation, especially violet spot color inks for gravure printing applications, which cannot be accurately reproduced through conventional process printing systems (CMYK). This research aims to optimize the production parameters of violet gravure inks that often exhibit color instability due to delays in the grinding and adjusting stages. The main focus of this research is to analyze the effect of variations in grinding duration, post-grinding aging time, and the amount of raw material on ink color yield, which is evaluated based on density, CIE Lab*, and ΔE parameters. The methodology used was a descriptive experiment on a laboratory scale. The results showed that the optimal treatment combination of grinding for 90 minutes, aging for 48 hours, and the use of 400 grams of material (P3K2L4) produced the highest density value (1.858) and ΔE (0.572), indicating color stability despite quantity variations. This finding indicates that optimization of grinding and aging time contributes to the improvement of pigment dispersion homogeneity and thermal stability of the resin, even without direct measurement of the transition glass temperature (Tg) value.

This research aims to analyze the optimization of legal protection and risk mitigation for PT ASDP Indonesia Ferry (Persero) as the lender in a Shareholder Loan (SHL) Agreement with PT Indonesia Ferry Properti, and to examine the legal implications of the PT ASDP directors' liability in the SHL decision-making process. The research method employed is normative juridical with a literature study approach. The findings indicate that although the SHL execution has procedurally met legal principles and Good Corporate Governance (GCG), the optimization of legal protection for PT ASDP requires the enhancement of more proactive post-disbursement fund supervision clauses and, crucially, the implementation of specific collateral to mitigate credit risk, considering the current agreement is still reactive and lacks specific collateral. Furthermore, the directors of PT ASDP bear responsibilities under Article 97 of the Company Law and the principle of fiduciary duty. The Business Judgment Rule (BJR) doctrine can shield directors from personal liability if decisions are made in good faith, with due care, without conflicts of interest, and accompanied by risk mitigation efforts, wherein the implementation of GCG principles is fundamental. Violations may lead to civil, criminal, or administrative liability. This research concludes the importance of contractual strengthening of the SHL and strict adherence to GCG to protect company assets and directors.

This study examined efforts to optimize the functions and roles of the Regional People's Representative Council (DPRD) of Pemalang Regency in overseeing policies related to the use of the Regional Revenue and Expenditure Budget (APBD). The optimization focused on strengthening the oversight mechanisms, enhancing the technical capacity of the DPRD, and improving inter-institutional coordination to support accountable budget governance. The study was motivated by the persistent weaknesses in legislative oversight, as evidenced by various findings of budget irregularities, including overpayments, misuse of grant funds, and unilateral budget decisions by the executive. A descriptive qualitative approach was used, with data collected through in-depth interviews with members of Commission C, the Budget Committee, and expert staff from the DPRD Secretariat, as well as through document analysis. The findings indicated that the implementation of DPRD’s oversight functions had followed formal mechanisms such as the evaluation of the accountability report (LKPJ) and the discussion of the General Budget Policy and Provisional Budget Ceiling (KUA-PPAS). However, the oversight had not been optimal due to limited access to information, insufficient technical capacity, and weak inter-agency synergy. The DPRD had formulated several optimization strategies, including internal capacity building, the use of digital information systems (SIPD), and strengthening coordination with the Audit Board (BPK) and the regional inspectorate. Therefore, optimizing the DPRD’s oversight function required systemic improvements encompassing institutional capacity, information transparency, and active public involvement in monitoring regional budgets.
