Abstract

Indonesia is a country with a diversity of ethnicities, cultures, races, and religions, which reflects the principle of Bhinneka Tunggal Ika. Although this diversity is a source of harmony, social and religious-based conflicts are inevitable, as seen in the cases in West Java. This paper explores the role of the Religious Harmony Forum (FKUB) as a mediator in resolving religious conflicts. Using the conflict cycle framework, this paper analyzes the dynamics of conflict, starting from the basis of conflict to its resolution. This research highlights the challenges of FKUB in maintaining neutrality, limited authority, and the importance of the government's role in creating policies that support religious harmony. Short, medium, and long-term action plans are formulated to strengthen the role of FKUB, enhance interfaith dialogue, and build a network of cooperation with various related parties. The conclusion shows that strengthening FKUB and tolerance education are key steps to encourage the sustainability of peace in society.

Abstract

The inconsistency between the selection of construction contract types and the completeness of planning products as tender documents has become a persistent problem in Indonesian government procurement, frequently leading to variation orders, cost overruns, risk misallocation, and audit findings. This research aims to analyse the legal relationship between the completeness of planning products and the selection of construction implementation contract types, as well as to identify the legal implications of such mismatches under Indonesia's goods and services procurement law. This study employs a normative legal research method using a conceptual approach and case studies of sports stadium renovation projects. The analysis is carried out through Lawrence M. Friedman's Legal Systems Theory, which encompasses three components: the substance of the law, legal structure, and legal culture. The results of the study show that the lack of synchronisation between contract types and the readiness of tender documents constitutes a systemic failure. The substance of the law has not provided operational parameters; the institutional structure does not perform a control function from the planning stage; and the prevailing legal culture remains oriented toward the transfer of risk and the shifting of responsibility rather than sound technical planning. The study recommends establishing minimum standards of planning completeness as a prerequisite for the qualification of tender documents for lump sum contract types, strengthening the role of Construction Management (Manajemen Konstruksi) from the initial planning stage, and shifting the paradigm toward technical data-based risk management.

Abstract

Geopolitical tensions in the Middle East have increased uncertainty in petrochemical and polypropylene supply, reducing plastic raw material availability and forcing plastic injection companies to improve process efficiency, minimize scrap, and reduce production losses. In automotive component manufacturing, the Cover Defroster product still faces short shot defects caused by incomplete molten plastic flow into the mold cavity. Many injection molding companies also still rely on trial-and-error machine settings, which increases material waste, setting time, and production cost. This study aims to optimize injection molding parameters using the Taguchi method and Moldflow simulation to eliminate short shot defects and minimize cycle time.  This research used a computer simulation-based experimental design. The product studied was a polypropylene type LA880T. Four process parameters were tested using an Orthogonal Array L16, namely injection pressure, mold temperature, melt temperature, and injection time. Moldflow Insight was used to simulate material flow, while ANOVA, Tukey test, and Signal-to-Noise Ratio with the Smaller-the-Better approach were used to analyze cycle time performance.  The simulation showed that trials 1 to 4 produced short shot defects and were rejected. ANOVA results showed that injection time had a significant effect on cycle time, while injection pressure, mold temperature, and melt temperature had no significant effect. The best parameter combinations were trials 6, 12, and 15, which produced good products without short shot defects and achieved the shortest cycle time of 24.12 seconds. The integration of Taguchi and Moldflow effectively supports parameter optimization, reduces defect risk, and improves injection molding process efficiency.

Abstract

This study addresses the growing demand for efficient renewable energy conversion systems, particularly in low- to medium-wind-speed regions such as Indonesia, where wind resources typically range between 4–6 m/s. Permanent magnet generators (PMGs) are widely used in wind power plants due to their high efficiency and simple structure; however, their performance is often limited by cogging torque, which causes rotational resistance, vibration, and reduced energy conversion efficiency. This research aims to analyze and optimize the reduction of cogging torque in a 28-pole, 24-slot permanent magnet generator through geometric modification techniques. The study employs a quantitative simulation approach using FEMM 4.2 software and LUA 4.0 scripting to model magnetic flux distribution and torque characteristics. The optimization process includes variations in air gap widening, magnet edge shaping, slot opening adjustment, and the addition of dummy slots. The initial design produced a cogging torque of 0.00498 Nm. After the first optimization stage, the value decreased to 0.00028 Nm, while the second optimization achieved a significant reduction to 0.00005 Nm, corresponding to a 98.99% decrease. The results demonstrate that combining magnet edge shaping with dummy slots is highly effective in minimizing cogging torque and improving flux uniformity. In conclusion, the optimized design enhances generator performance, particularly in low-speed wind applications, making it a promising solution for sustainable energy development.

Abstract

This study aims to explore the dynamics of the quality of life of tuberculosis (TB) patients in Palembang City through a phenomenological study. Tuberculosis is not merely a physical disease that attacks the respiratory system, but also has a significant impact on the psychological aspects and overall well-being of patients. The high incidence of TB in Palembang City, which records the highest cases in South Sumatra Province, underscores the importance of understanding the perceptions and lived experiences of those affected. The method used in this study is descriptive qualitative with a phenomenological approach. The research subjects consisted of two TB patients with a history of disease relapse (initials AS and F), supported by two knowledgeable informants from the family and Patient Support Group. Data were collected through in-depth interviews and documentation techniques. Data analysis was conducted using the Miles and Huberman model and the Spradley model to draw systematic conclusions. The results of the study indicate that both subjects were able to achieve an adequate level of quality of life despite having to face physical challenges due to treatment side effects and psychosocial burdens in the form of stigma and limited social interaction. The dynamics of a patient's quality of life are significantly influenced by several key factors, including microsystem (family) support, access to government health services, and spiritual strength and internal motivation to recover. Adaptability and effective emotional regulation have been shown to be crucial elements in maintaining well-being throughout long-term treatment.

Abstract

Delays in Public-Private Partnership (PPP) projects are often attributed to financial constraints or technical challenges, while institutional dynamics and actor interactions remain underexplored, particularly at the local government level. This study aims to analyze actor dynamics within the institutional framework of the Street Lighting PPP project in Denpasar City, Indonesia. A case study approach was employed by integrating MICMAC structural analysis and MACTOR actor analysis to identify key variables, map influence structures, and examine actors' strategic positions toward project objectives. The findings reveal that regulatory change functions as an external structural shock that restructures inter-actor relationships and increases coordination complexity. The actor structure demonstrates a pattern of mutual interdependence, where highly influential actors simultaneously exhibit high dependence. This configuration produces a collective yet defensive decision-making mechanism, as actors tend to minimize institutional risk and individual accountability. Consequently, project delays cannot be understood solely as technical or financial issues, but rather as outcomes of relational configurations requiring collective legitimacy before strategic decisions are made. This study highlights the importance of incorporating actor dynamics analysis as a diagnostic tool in PPP preparation stages to strengthen coordination, align regulatory interpretation, and enhance implementation certainty.

Abstract

PT. OGC faces inaccuracies in diesel and jet fuel forecasting, leading to inventory shortages, higher logistics costs, and potential public dissatisfaction, which also impacts Indonesia's energy self-sufficiency and oil-gas trade deficit. This research proposes improvements to diesel and jet fuel planning management at PT. OGC using the Six Sigma DMAIC methodology to identify root causes of inventory issues and enhance planning accuracy. A mixed-methods approach was employed, combining primary and secondary data with SIPOC analysis, forecast error measurements (MAD, MAPE, DPMO, sigma level), correlation analysis, fishbone diagrams, Pareto charts, and process capability indices (Cp, Cpk). Simulations validated the proposed solutions. Current forecasting accuracy is below acceptable levels: diesel MAPE at 5.89% (exceeding the 5% SLA tolerance) and jet fuel MAPE at 11.26%. Cp and Cpk remained below 1.0. Root causes included weak forecasting methods, misaligned turnaround schedules with demand, and emergency shutdowns. Improvement initiatives reduced forecast errors: the ARIMA–XGBoost hybrid model lowered diesel MAPE to 4.21%, and the SARIMA–LSTM hybrid model reduced jet fuel MAPE to 4.00%. The proposed improvements effectively reduce forecasting errors, increase production stability, and decrease stock problems. Recommendations include adopting hybrid AI/ML forecasting models, aligning turnaround schedules, digitizing preventive maintenance, and implementing a monitoring dashboard with regular audits.

Abstract

Butter cookies are one of the most popular food products due to their crispy texture and distinctive flavor. Tempeh flour, as a source of plant-based protein, and kepok banana peel flour (Musa paradisiaca Linn.), as a source of dietary fiber, have significant potential to be utilized as functional ingredients in cookie product development. This study aimed to determine the effect of combining tempeh flour and kepok banana peel flour on the chemical and organoleptic quality of butter cookies. This research employed a laboratory experimental method using a Completely Randomized Design (CRD) with one factor, namely variations in flour combination concentrations: T1P1 (90% : 10%), T2P2 (80% : 20%), T3P3 (70% : 30%), and T4P4 (50% : 50%), each with three replications. The observed variables included chemical quality (moisture content, ash content, protein content, and fiber content) and organoleptic quality (color, aroma, taste, texture, and overall acceptability) of butter cookies. Parametric data were analyzed using Analysis of Variance (ANOVA) with the assistance of Statistical Product and Service Solutions (SPSS) software, while non-parametric data were analyzed using Duncan’s Multiple Range Test (DMRT). Based on the effectiveness test using the De Garmo method, treatment T2P2 was selected as the best treatment with a total score of 0.626, producing the most optimal physicochemical and organoleptic characteristics.

Abstract

This research aims to analyze the effect of firm size and capital structure on the financial performance of banking companies listed on the Indonesian Stock Exchange during the 2021–2024 period. Financial performance is proxied by Return on Assets (ROA), firm size is measured by total assets, and capital structure is measured using the Debt to Equity Ratio (DER). This research employs a quantitative approach with panel data regression analysis using secondary data obtained from annual financial reports. The model selection tests indicate that the Random Effect Model is the most appropriate. The results show that firm size has a positive and significant effect on financial performance, indicating that larger banks tend to achieve higher profitability due to better resource utilization and operational efficiency. Meanwhile, capital structure has a negative and significant effect on financial performance, suggesting that higher leverage increases financial risk and financing costs, which may reduce profitability. Simultaneously, firm size and capital structure significantly affect the financial performance of banking companies. These findings imply that banks should optimize asset management and maintain a balanced capital structure to improve profitability and ensure sustainable financial performance.
