Authors: Hasan Isran K , Janur Muhammad , Nurwan Nurwan
Published: October 2024

Emas menjadi salah satu aset keuangan bagi negara dan menjadi komponen cadangan moneter global untuk perdagangan dan perlindungan ketika menghadapi krisis keuangan secara tiba-tiba. Beberapa data ekonomi sering mengalami ketergantungan atau dependensi jangka panjang (long memory). Salah satu model yang mampu mengatasi masalah tersebut adalah model Autotegressive Fractionally Integrated Moving Average (ARFIMA). Ada beberapa metode yang digunakan untuk menentukan estimasi parameter pembeda d yaitu metode Geweke and Porter Hudak dan metode Rescaled Range Statistics (R/S). Pada beberapa tipe data runtun waktu terkadang mengalami pengelompokan volatilitas (residual tidak konstan). Metode yang dapat digunakan untuk mengatasi masalah tersebut adalah metode Generalized Autoregressive Conditional Heteroskedasticity (GARCH). Tujuan dari penelitian ini adalah untuk memodelkan harga emas antam produksi PT. Aneka Tambang menggunakan metode ARFIMA-GARCH serta membandingkan metode estimasi parameter pembeda d terbaik dari model tersebut. Hasil penelitian ini menunjukan model terbaik dilihat dari nilai AIC untuk dgph = 0, 105 adalah ARFIMA(1,d,1)-GARCH(1,1) dan model terbaik untuk dR/S = 0, 288 adalah ARFIMA(1,d,1)-GARCH(1,1). Tingkat akurasi peramalan didasarkan pada nilai MAPE. Nilai error validasi model ARFIMA-GARCH dengan dgph = 0, 105 adalah MAPE=3,474%, sedangkan model ARFIMA-GARCH dengan dR/S = 0, 288 adalah MAPE=3,444%.

Authors: Alim Khairul , Matsaany Bayun , Rahmawati Anisa
Published: October 2024

Investment is placing funds into an asset to gain profits in the future through changes in asset prices or capital gains. In Indonesia, stock investment, primarily through the Indonesia Stock Exchange (BEI), is popular among the public. BEI offers various indices, including the Jakarta Islamic Index (JII), which has garnered significant attention. JII comprises stocks of companies that adhere to Sharia principles. In investment, careful analysis is crucial to avoid errors in stock selection. Diversification is a strategy that involves spreading investments across several stocks, aiming to maximize profits while minimizing risks. While the easiest way for investors to enter the stock market is by purchasing the best-performing single stock, relying solely on one stock can be risky if its price drops. This research compares investment outcomes between single-stock and diversified portfolios of two or three stocks, selected based on the Sharpe, Treynor, and Jensen indices. The research analyzes the closing stock prices within the JII index from March 2018 to February 2023. The study results show that diversifying investments across multiple stocks can reduce investment risks, even though it may reduce profit potential.

This research aims to analyze the disclosure of environmental information in the financial statements of the Regional Drinking Water Company (PDAM) of Bondowoso Regency, considering the perspectives of green economy and corporate social responsibility. The disclosure of environmental information is increasingly important in the context of environmental protection and business sustainability. A qualitative approach is used to analyze the financial statements of PDAM Bondowoso Regency with a focus on environmental information disclosure elements. Findings from this research are expected to provide new insights into environmental information disclosure practices in the public sector, especially in regional companies such as PDAM. The implications of this analysis can contribute to the development of green economy and corporate social responsibility in Bondowoso Regency and encourage other companies to improve transparency and accountability in disclosing environmental information in the financial statements of PDAM Bondowoso Regency. In conclusion, the management of waste by PDAM Bondowoso Regency still has shortcomings, such as suboptimal waste treatment, gaps in handling various types of waste, technological limitations, and lack of awareness or understanding. The disclosure of environmental information in financial statements is also constrained by factors such as lack of awareness, resource constraints, and regulatory uncertainty.

The article provides a theoretical analysis of the approaches identified by the authors to the definition of the concept of “regional personnel security”: as the state of human capital, as the state of the labor market, an element of the economic security system at various levels, as a process of preventing various negative impacts on economic security at the national, regional and corporate levels. The importance of human potential as an object of attention in ensuring personnel security at the regional level is noted. The role of investments in human potential from the point of view of various spheres of public life as a factor in the economic growth of territories is outlined. Based on an analysis of modern research in the area under study, two positions have been identified to determine the place of personnel security in economic and national security systems. The author’s concept of personnel security is proposed. The place of personnel security in the region’s economic security system has been determined.

The Multidimensional Knapsack Problem (MKP) is a challenging combinatorial optimization problem that extends the classical knapsack problem by introducing multiple capacity constraints across various dimensions. This problem has significant practical applications, including resource allocation in supply chain management, portfolio optimization in finance, and cargo loading in logistics, where the goal is to maximize the total profit of selected items while adhering to these constraints. In this research, the CPLEX solver was applied to address the MKP using a set of complex instances from the OR-Library, specifically the ORX Benchmarks. The study focuses on 270 MKP instances characterized by varying numbers of variables (n = 100, 250, 500), constraints (m = 5), and tightness ratios (α = 0.25). Through advanced CPLEX techniques, new results were successfully obtained by employing advanced CPLEX methods, contributing to the existing literature, and setting new benchmarks for these instances.
A Primer on the Theory, Practice, and Pedagogy Underpinning a School of Thought on Law and Business
Authors: Holloway James
Published: October 2024

Recent policyless and lawless business decisions have prompted the judiciary and legislature to erode managerial discretion and judgment. This Article is a primer on the theoretical, practical, and pedagogical requirements for a legal-managerial school of thought to measure the business losses created by these judicial and legislative responses. A legal-managerial school must provide a theoretical evaluation of law and public policy, a practical integration of legal analysis and business methodology, and a pedagogical expansion of legal thinking to include business information. This Article initiates the debate on how a legal-managerial school of thought can further the study, practice, and teaching of jurisprudence and business disciplines, and ultimately provide lawyers and managers with tools for business decision making.

In the dynamic landscape of Ad Tech, product managers play a critical role in translating business objectives into functional digital products. Wireframing serves as a foundational tool, providing a visual guide to represent user interface elements and flow before development begins. This practice is particularly crucial in Ad Tech due to the fast-paced, highly iterative nature of the industry. Wireframes allow product managers to communicate concepts clearly, align cross-functional teams, and ensure that both user experience (UX) and key performance indicators (KPIs) are met. Best practices for wireframing in Ad Tech include focusing on simplicity, fostering collaboration between designers and developers, and ensuring flexibility to accommodate changes in ad formats, targeting technologies, and platform specifications. Effective wireframes prioritize the balance between user needs and monetization strategies, which is essential in a competitive environment where ad performance and user experience must co-exist. Additionally, prototyping tools like Figma and Sketch help in refining wireframes into interactive prototypes, enabling stakeholders to visualize the flow of ads across different platforms. By adhering to these best practices, product managers can streamline the product development cycle, reduce miscommunications, and ultimately build more effective and engaging ad solutions.
THE INFLUENCE OF COUNTY ASSEMBLIES’ COORDINATING ROLE ON THE IMPLEMENTATION OF STRATEGIC PLANS IN THE NAIROBI CITY COUNTY GOVERNMENT, KENYA

In Nairobi County, just like the rest of Kenya, the county assembly is responsible for legislation, oversight, and representation of the county executive who implements the county strategic plans developed from the devolved functions of the devolution. However, the achievement of strategic plans is still with flaws despite this. The purpose of the study was to assess the influence of the coordinating role on the implementation of strategic plans in the Nairobi City County Government, Kenya. The study was guided by the McKinsey 7s model, the Dynamic Capability Model, and the Resource-Based View Theory. The study was conducted using a quantitative research design. The target population was 123 members of the County Assembly, consisting of 85 elected and 38 nominated members. The population also included 3 officials from the County Assembly's Financial and Budget Office, Procurement Office, and Planning Department. The study involved 85 elected and 38 nominated county assembly members, using simple random sampling. Officials from the Financial and Budget Office, Procurement Office, and Planning Department were selected by census. Primary data was collected with 5-point Likert scales. SPSS regression analysis tested the relationships between dependent and independent variables, with multiple regression used due to activity interconnectedness. Results were presented in descriptive figures and tables, with regression outcomes shown in tables. The study's findings reveal a strong positive correlation (r = 0.847, p < 0.01) between the coordination role of MCAs and the implementation of strategic plans. The standardized coefficient (β =0.847; p =0.000) confirms the strong positive relationship between the coordination role and strategic plan attainment. The differing views among MCAs on coordination roles highlight the need for NCCG to enhance stakeholder engagement by creating clear communication frameworks, organizing regular interaction forums, and involving stakeholders in resource allocation to align their efforts with strategic objectives and improve the execution of strategic plans.

The use of electric motors in industry often experiences damage caused by several things, including high starting current surges, overload or full load, loss of one phase in the electric motor, and other causes of damage to the 3-phase motor. The main problem that occurred in this research was damage caused by high starting currents, where in the case study many 3-phase motors were used to drive factory machines. The use of 3-phase motors to drive factory machines is often damaged by unstable currents in the machines. This is because the time and workers for monitoring are very minimal and the materials for repairing machines are inadequate. In this way, the solution for repairing a 3-phase motor is to replace and rewind the damaged motor so that it can be used again. This research aims to find a solution on how to reduce high starting currents in 3-phase motors by utilizing the influence of replacing damaged induction motor components as well as repair methods used in starting when rewinding 3-phase motors. The research results from the groove distance with a wire size of 0.90 mm showed that the groove distance of 9, 9, 8 was 29.3, and at a distance of 10, 10, 10 it had a current of 31 A with no-load testing and recommended groove distances of 10, 10, 10. Next, testing wire sizes of 0.75 mm and 0.90 mm with distances of 10, 10, 10, and 9, 9, 8 without load obtained 26.1 A and 27.4 A while 0.90 mm was 30, 7 A and 28, 1 A. The load was 43.5 A and 43.9 A, while 0.90 mm was 51.3 A and 49.3 A. From the test results, the largest current decrease was at a distance of 10, 10, 10 with a wire size of 0.75 mm.
