Abstract

Based on Decree No. 556/Kep.770-Disbudpar/2022, issued in 2002, Sugihmukti Village in Bandung Regency was officially designated as a tourism village. Sugihmukti Village is known for its birdwatching activities conducted in collaboration with "Burung Indonesia" community which have drawn both domestic and international visitors. Aside from birdwatching, the tourist attractions offered by Sugihmukti Village are not significantly different from those of nearby villages. As a result, Sugihmukti Village is striving to enhance its brand recognition among tourists. We believe that through business model design training, the residents of Sugihmukti Village can uncover their hidden potential and establish a sustainable economic foundation for the future. Economic development at the village level plays a crucial role in improving community welfare. To promote economic development, training about designing business model in Sugihmukti Village is required. This training aims to empower the local community with skills that can boost the village's competitiveness and eventually economic welfare. Thus, a training session titled “Business Model Design Training in Sugihmukti Village, Bandung Regency.” This training is expected to have a significant positive impact on Sugihmukti Village by raising awareness on value proposition, optimizing local resources to enhance key activities, developing partnerships and networks, ensuring sustainability and risk mitigation, and improving community welfare. The delivery method of this training is a direct approach to the residents of Sugihmukti Village particularly those who are directly involved in managing the tourism village. The training is designed to deliver an effective learning process that will enhance both individual and group competencies in tourism. Hopefully, through this training, Sugihmukti Village can present itself as a unique and attractive tourist destination.

Abstract

This study analyzes the formation of optimal portfolios on cryptocurrency assets using the single index model and the Harry Markowitz model. This study covers 79 cryptocurrencies with the largest market capitalization during the period June 2023–June 2024. We calculate the optimal portfolio using the single index model and Markowitz, and evaluate its performance using the Sharpe Ratio. The results show that the Harry Markowitz model produces better portfolio performance compared to the single index model. The Markowitz portfolio produces a positive Sharpe ratio (1.8496), a portfolio return rate of 7.678%, and lower risk (0.0415). Conversely, the single index model portfolio shows a negative Sharpe ratio (-2.0971), indicating lower returns than risk-free assets. In addition, the Markowitz model offers more efficient diversification than the single index model. However, in general, both the Single Index Model and the Markowitz Model have a significant effect on the formation of optimal portfolios, with the Sharpe Index proving to be a significant mediator in the relationship between the two models and the optimal portfolio. The R-squared value shows that the SIM variables, Markowitz Model, and Sharpe Index explain 48.4% of the variation in the optimal portfolio. This study recommends the use of the Harry Markowitz model for cryptocurrency investment because it can provide higher returns with more controlled risks. This study provides important insights for investors on the strategy of diversifying cryptocurrency asset portfolios.

Abstract

The construction industry in Indonesia decreasing in profits in the 2019-2023 period, with several large companies recording consecutive losses. This study aims to analyze the effect of profitability and managerial ownership on financial distress and identify whether capital structure strengthens this effect of construction companies. Quantitative and moderated regression approach was used with secondary data financial statements of construction companies listed on Indonesia Stock Exchange (IDX) during 2019-2023. The results indicate profitability has a significant effect on financial distress. Conversely, managerial ownership not significant, but when combined with profitability, it can reduce the chance of financial distress. Capital structure not strengthen the profitability and financial distress, but reinforce the influence of managerial ownership. High managerial share ownership and balanced capital structure debt and equity, helps companies avoid financial distress. This study recommends that financial management in construction companies focus on enhancing profitability and managing capital structure to prevent financial distress.

Abstract

The Indonesia Sharia Stock Index (ISSI) serves as a key indicator of sharia-compliant stock performance on the Indonesia Stock Exchange. This study investigates the impact of macroeconomic factors—interest rates, exchange rates, inflation, oil prices, and gold prices—on ISSI volatility from January 2015 to December 2024. Utilizing a quantitative approach with multiple regression analysis, the findings reveal that interest rates significantly negatively affect volatility (coefficient -0.509, significance 0.001), indicating that higher interest rates reduce market volatility. In contrast, the exchange rate and inflation show no significant effects (coefficients -0.308 and 0.144). World oil prices have a marginal negative impact (coefficient -0.200), while gold prices are not significant (coefficient 0.045). ANOVA results confirm that all independent variables collectively influence ISSI volatility significantly (significance 0.005). This research underscores the importance of macroeconomic factors in investment decision-making within the sharia market and suggests future studies incorporate sectoral analysis and additional control variables for deeper insights.

Abstract

This study aims to analyze non-financial factors that influence underpricing in companies conducting Initial Public Offerings (IPOs) on the Indonesia Stock Exchange during the period 2021 to 2023. The variables analyzed include industry sector, issue size, underwriter reputation, auditor reputation, and legal consultant reputation. The research employs a quantitative approach with an explanatory design and uses binary logistic regression analysis. The sample consists of 187 firms selected using purposive sampling. The results show that the underpricing phenomenon remains prevalent in Indonesia. Among the variables studied, issue size and auditor reputation have a significant influence on underpricing. These findings indicate the importance of strong market signals in reducing information asymmetry between issuers and investors. This research contributes to the IPO literature in emerging markets and provides practical implications for companies, investors, and capital market authorities.

Abstract

Purpose - This study investigates the construction of optimal stock portfolios using the Single Index Model (SIM) and the Markowitz Mean-Variance Model (MM), applied to the IDX High Dividend 20 (IDXHIDIV20) index. With a growing number of novice investors in Indonesia, understanding which classical model offers better guidance for dividend-oriented investing is increasingly essential. Design/methodology/approach - A descriptive quantitative approach was used, employing weekly secondary data of 20 IDXHIDIV20 constituents from 2019 to 2024. The SIM was applied through regression-based estimations and excess return-to-beta ranking, while the Markowitz Model utilized a full variance-covariance matrix with Excel Solver optimization. Originality -  This research contributes empirical evidence to modern portfolio theory by comparing the effectiveness of SIM and MM in the context of novice investors in emerging markets. It also incorporates the relevance of sustainability factors through dividend strategies. Findings and Discussion - The Markowitz portfolio consistently outperforms the SIM portfolio in both return and risk dimensions, achieving an expected annual return of 23.56% with a standard deviation of 2.81%, compared to SIM's 22.96% return with 5.89% volatility. While the SIM offers practical simplicity for novice investors, the MM provides superior diversification through covariance-based optimization. These findings validate the importance of robust model selection in portfolio strategy. Conclusion - The Markowitz Model is preferable for investors with access to analytical tools and data due to its superior risk-return performance, while SIM remains a valuable approach for those with limited resources. The study enhances financial education and supports informed investment decisions for dividend-focused strategies in emerging markets.

Abstract

Currently, the electricity system of North Sulawesi Province is supplied by power plants including Geothermal Power Plant (GPP), Coal-fired Power Plant (CFPP), Hydroelectric Power Plant (HPP), Solar Power Plant (SPP), Diesel Power Plant (DPP), and Gas Turbine Power Plant (GTPP) with a total installed capacity of 589 MW. The Net Capacity (NC) of this system is approximately 492 MW and the Net Supply Capacity (SC) is around 462 MW, resulting in a gap between installed capacity, NC, and SC Over the past few years, the electricity sales growth in North Sulawesi Province has been quite high, around 7.8% based on sales data from 2011-2020, and is projected to continue growing. Additionally, it is expected that the Energy Mix from New and Renewable Energy sources should reach 23% by 2025, thus the development of new power plants from New and Renewable Energy sources can contribute to achieving this Energy Mix. This research is conducted as a further study regarding the feasibility of investing in the development of XYZ Geothermal Power Plant to provide added value for the company. The research method employed is quantitative descriptive method, which involves calculating the Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI), Discounted Payback Period (PP), and Sensitivity Analysis (SA). The results show that the investment will be feasible if the capital source for the investment comes from corporate loans for the upstream sector and soft loans for the downstream sector of development, resulting in an NPV of 2,241 thousand USD, an IRR of 11.11%, a PI of 1.01, and a PP of 24 years. Furthermore, the analysis shows that the decision on the capital source is important, as it affects feasibility, and loan variables such as the interest rate in corporate loans and repayment years in soft loans are important factors to consider in increasing economic feasibility. On the other hand, if the best scenario is chosen—decreasing cost variables and increasing both the electricity tariff and capacity factor by 10% from the base scenario—it can result in higher economic feasibility. Moreover, the electricity tariff, capacity factor, production well cost, and power plant cost have the greatest impact on feasibility. Therefore, it is important to strive for the maximum value of the electricity tariff and capacity factor, while minimizing production well and power plant costs as efficiently as possible.

Abstract

The telecommunications industry in Indonesia faces numerous challenges in allocating resources for network development, including network complexity, technological changes, market competition, and customer expectations. To achieve optimal financial outcomes and customer satisfaction, investments must be well-managed, well-placed, and well-executed. This study analyses network investment portfolio selection outcomes at Telkomsel; Indonesia's largest cellular operator, comparing conventional scenarios (financial and network) with an optimized scenario using Mixed Integer Linear Programming (MILP). The research evaluates these scenarios based on total portfolio score, incremental revenue, and Internal Rate of Return (IRR). Financial indicators such as net present value (NPV), IRR, EBIT margin, incremental revenue, and network indicators such as capacity and customer satisfaction (download/upload throughput, latency, packet loss, jitter) assess investment feasibility. The MILP optimization scenario strongly correlates with incremental revenue, NPV, and IRR, indicating higher financial performance. Sites selected in the MILP optimization outperscenario formed others in total score (22% better than the financial scenario, 63% better than the network scenario), incremental revenue (3.5% better than the financial scenario, 90.2% better than the network scenario), and portfolio IRR (4% better than the financial scenario, 70% better than the network scenario).
