The rapid growth of beverage franchises in Indonesia, particularly MIXUE with over 4,000 outlets, necessitates an in-depth examination of the financial management strategies underlying its success. This study aims to analyze the effects of working capital management, supply chain support, and operational cost efficiency on financial performance, as well as to evaluate the investment feasibility of the MIXUE franchise in Indonesia. A mixed-methods sequential explanatory approach was employed, utilizing multiple regression analysis and capital budgeting methods including Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Return on Investment (ROI). Data were collected from 50 franchise outlets across Jakarta, Bandung, Surabaya, and Semarang during 2022-2024, supplemented by in-depth interviews with 15 franchisees and 3 regional managers. Results reveal that all three independent variables significantly and positively affect financial performance: working capital management (β = 0.412; p = 0.002), supply chain support (β = 0.358; p = 0.008), and operational cost efficiency (β = 0.486; p < 0.001) with R² = 0.684. Investment feasibility analysis indicates an average positive NPV of IDR 290.1 million, IRR 36.5%, PP 22.2 months, and ROI 56.5%. This study contributes novel insights by integrating financial and supply chain analysis within the context of beverage franchising in emerging Asian markets, providing a comprehensive evaluation framework for prospective investors and franchise system developers.

The study aims to analyze in greater depth the influence of work motivation and employee loyalty on employee performance at PT ABC. This research employs a quantitative approach with an explanatory design intended to systematically explain the relationships among variables. Data were collected through the distribution of questionnaires using a Likert scale (1–5) to employees with a minimum of one year of tenure, as they are considered to have an adequate understanding of organizational conditions. Data analysis was conducted using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method with the assistance of SmartPLS 4 software to obtain more accurate and comprehensive results. The findings indicate that all research indicators have met the established validity and reliability criteria. The structural model test shows that work motivation has a positive and significant effect on employee performance (β = 0.207; p = 0.007), and employee loyalty also has a positive and significant effect (β = 0.718; p = 0.000). The R-square value of 0.753 indicates that both variables are able to explain 75.3% of the variation in employee performance. These findings emphasize that work motivation and employee loyalty play important roles in improving performance, with loyalty being the most dominant factor influencing employee performance.

This study aims to analyze the impact of women’s dual roles and work stress on the work quality of female employees in the Production Division of PT Unggulrejo Wasono, Purworejo. The background of this research arises from the phenomenon of married female workers who must balance household responsibilities with factory production demands, a condition that often leads to stress and decreased work performance. Using a qualitative approach, data were collected through observation, in-depth interviews, and documentation, and analyzed using Miles and Huberman’s interactive model. The findings reveal that dual roles significantly influence work quality, with many female employees experiencing physical and mental fatigue that lowers concentration, accuracy, and productivity. Work stress is triggered by excessive workloads, high production targets, uncomfortable working conditions, and limited interpersonal support. There are three findings: (1) negative impacts on female employees without family support; (2) dual roles serve as a motivator when supported by spouses or parents; and (3) fluctuating effects depending on household and work conditions. The research implications affirm that PT Unggulrejo Wasono's efforts to address dual roles and work stress remain limited but somewhat helpful. Counseling programs and stress management training have had a positive impact on some female employees, although the effects are not yet widespread due to the absence of structural policies such as workload adjustments or childcare support. As a result, the work quality of employees who receive support tends to be more stable, while those without support remain vulnerable to decreased productivity and increased absenteeism. Therefore, while the existing  efforts  are beneficial,  their  effectiveness  needs  to  be improved  to  achieve broader  positive outcomes.

Martial arts training centers are essential facilities that support the technical, physical, and mental development of athletes. This study aims to identify the facility requirements and architectural design criteria for martial arts training centers in Surabaya. A qualitative descriptive method was employed, utilizing literature reviews, field observations, and interviews with relevant stakeholders. The findings indicate that the required facilities include a main training area, supporting spaces, and operational support facilities, all of which must be designed in accordance with the specific characteristics of each martial art discipline. Furthermore, the implementation of appropriate zoning systems and design criteria—such as flexibility, safety, comfort, and functional integration—plays a significant role in enhancing the effectiveness of the training environment. Properly designed facilities not only accommodate diverse training needs but also contribute to optimizing athlete performance. Therefore, a comprehensive architectural approach is necessary to ensure that martial arts training centers can function efficiently and sustainably in supporting long-term athlete development.

This study analyzes the performance of the Dual Modulus RSA algorithm in securing text data using Python. The rapid growth of digital technology has increased the risk of data security threats, making efficient and secure encryption essential. Dual Modulus RSA is a modification of the classic RSA algorithm that uses two different moduli in the encryption and decryption process, thus increasing security levels because attackers must factorize two moduli simultaneously. This research uses an experimental quantitative approach by measuring the execution time of encryption and decryption processes with variations in plaintext length (5, 10, and 15 characters). Implementation was carried out using Python 3 with the time.perf_counter() function for microsecond-precision measurement. The results show that the Dual Modulus RSA algorithm successfully encrypts and decrypts all test plaintexts correctly. Encryption time ranged from 0.0212 ms to 0.0823 ms, while decryption time ranged from 0.0422 ms to 0.0955 ms. There is a positive linear relationship between plaintext length and processing time. Decryption is consistently slower than encryption due to the larger private key exponent (d1=2753, d2=3533) compared to the public exponent (e=17). The main factors affecting performance are exponent size, dual modulus overhead, CPU caching effects, and Python interpretation overhead. This study recommends using Dual Modulus RSA with hybrid encryption for practical implementation to balance security and performance.

The rapid growth of the Internet of Things (IoT) has driven numerous innovations in wireless communications that not only demand technical efficiency but also raise philosophical questions about the nature of scientific knowledge. One such innovation is Physical Layer Network Coding (PLNC), a communication technique that utilizes signal interference as a source of information to enhance system performance. This paper examines the philosophical dimensions of science within PLNC, focusing on three fundamental aspects: ontology, epistemology, and axiology. Ontologically, PLNC represents a new paradigm in wireless communication that reinterprets interference not merely as noise but as an opportunity. Epistemologically, knowledge of PLNC is derived through scientific methods such as mathematical modeling, experimentation, and simulation—yielding intersubjective and verifiable truths. Axiologically, PLNC holds practical value in terms of energy efficiency, data reliability, and contributions to the sustainability of IoT ecosystems, while also raising ethical considerations regarding privacy and information security. Thus, this study demonstrates that the development of PLNC cannot be separated from philosophical reflection, emphasizing the profound interconnection between technological advancement, scientific methodology, and human values.

This study analyzes the implementation of Good Governance in enhancing consular services at the Consulate General of the Republic of Indonesia in Tawau, using a qualitative approach with a case study paradigm. The findings reveal several key points: First, transparency in consular services is achieved through openness about procedures, fees, and service time standards via official platforms like websites, social media, and notice boards. This transparency reduces information asymmetry, prevents maladministration, and builds trust. Second, service accountability is reflected in the timely execution of passport renewals, Emergency Travel Documents, and document legalization, following Standard Operating Procedures (SOPs). Accountability is further demonstrated through performance reports, complaint channels, and service evaluations. Third, public participation is fostered through two-way communication, complaint mechanisms, and collaboration with Indonesian citizen and migrant worker communities. The mobile consular service program also enhances accessibility. Finally, consular services are based on clear legal frameworks, ensuring the legitimacy of services and protection for Indonesian citizens and migrant workers. Overall, the study concludes that the implementation of Good Governance principles at the Consulate General of Indonesia in Tawau significantly improves the quality of consular services.

The performance of asphalt mixtures is strongly influenced by the composition of their constituent materials, particularly aggregate size and mixing temperature during production. In many tropical and subtropical regions, asphalt pavements frequently experience rutting, reduced stability, and changes in viscoelastic properties due to high environmental temperatures and heavy traffic loads. These conditions can significantly affect pavement durability, making it essential to produce asphalt mixtures that meet established technical standards. This study aims to analyze the effect of variations in aggregate size distribution and mixing temperature on the Marshall characteristics of Asphalt Concrete Wearing Course (AC-WC) mixtures. The research employs the Marshall test method to evaluate the load-bearing capacity and stability of hot asphalt mixtures and to assess their compliance with ASTM/SNI standards. The results indicate that mixtures with standard aggregate gradation achieve stability values of 985 kg at 120°C, 1055 kg at 140°C, and 1107 kg at 160°C. As mixing temperature increases, flow values decrease, while the Marshall Quotient (MQ) increases, indicating improved stiffness. Higher temperatures also enhance compaction, reducing VIM and VMA while increasing VFA. Conversely, non-standard aggregate gradations result in several parameters failing to meet ASTM/SNI requirements, confirming that standard gradation produces superior asphalt performance.

Rice plants (Oryza Sativa L.) are the main staple food commodity in Indonesia, as most of the Indonesian population relies on rice as their primary food. One of the causes of low rice production in Indonesia is that farmers generally cultivate rice improperly, such as in land preparation or land selection. Land suitability in rice cultivation greatly affects crop productivity. A process that can support decisions regarding rice land suitability is the development of a Decision Support System (DSS) website using a combination of the Simple Additive Weighting (SAW) method and the Technique for Order Performance of Similarity to Ideal Solution (TOPSIS). This combination is performed by taking the average (µ) of the final results from the SAW and TOPSIS methods. The final scores of each method are calculated separately, and then the average (µ) of these two results is taken to obtain the final ranking of the alternatives. The data used to determine the suitability of rice land is based on five criteria: soil type, soil pH, rainfall, temperature, irrigation and water supply. The alternative data used in the study includes six alternatives: Sungai Kunjang, Sambutan, Samarinda Utara, Palaran, Loa Janan Ilir, and Samarinda Seberang. The aim of this research is to provide information on alternative solutions to farmers or farmer groups in determining rice land suitability. The results of the combination of the SAW and TOPSIS methods show that the alternative with the highest final score is Samarinda Utara (A3), with a final score of 0.7337. Meanwhile, the alternative with the lowest final score is Sambutan (A2), with a final score of 0.4402.

In addition, these digital platforms contribute to more inclusive and user-oriented public service systems. The purpose of this study is to analyze the effectiveness of technology in improving service delivery and to identify strategic steps that can be taken to address the challenges associated with service innovation in the public sector. Qualitative research methods were applied, utilizing data collection techniques through an extensive literature review of relevant academic and policy sources. The findings illustrate that technology-based innovation not only supports improved service performance but also strengthens accountability, responsiveness, and public participation in governance processes.

The Fréchet distribution is one of the commonly used Extreme Value Distributions (EVDs) in statistical modeling and heavy-tailed data analysis, where it plays an important role in describing product lifetimes as well as climatic and financial phenomena. The estimation of its two parameters, namely the shape parameter and the scale parameter, is traditionally based on the Maximum Likelihood Estimation (MLE) method. However, maximizing the likelihood function for this distribution involves numerical difficulties, which necessitates the use of numerical optimization methods. In this study, we propose the use of the Aquila Optimizer (AO), a recent metaheuristic algorithm inspired by the hunting behavior of eagles, as an efficient numerical tool for maximizing the likelihood function of the Fréchet distribution. The objective function was formulated as the negative log-likelihood function (-LogL), and the Aquila Optimizer was employed to obtain the optimal estimates of the distribution parameters. Several simulation experiments with different sample sizes were conducted to compare the performance of the proposed method with a conventional approach represented by the Nelder–Mead method, using the Mean Squared Error (MSE) criterion. The simulation results demonstrated that the Aquila Optimizer outperformed the Nelder–Mead algorithm in many cases, although the superiority was slight. The results also showed that both algorithms were consistent, as their MSE values decreased with increasing sample size. In addition, a practical application was carried out using real data, and the results of the survival function estimation indicated a good fit.

Bureaucratic reform in Indonesia has encouraged the strengthening of civil service management oriented toward performance through the policy of appointing Government Employees with Work Agreements (PPPK) in order to improve the effectiveness of public organizations. This study aims to analyze the performance of PPPK in supporting the implementation of tasks at the Environmental Agency of Jambi City by using Mangkunegara’s performance theory as the analytical framework. This research employs a qualitative approach with a descriptive method. Data were collected through in-depth interviews and documentation, and then analyzed using data reduction, data display, and conclusion drawing techniques. The results show that the performance of PPPK is generally in the good category and contributes positively to organizational effectiveness. This is reflected in the aspects of work quality, work quantity, and responsibility as explained in Mangkunegara’s performance theory. The alignment between job placement and competence, increased work motivation due to employment status certainty, and organizational support through training and coaching are the main factors supporting performance optimization. However, there are still constraints, particularly the suboptimal understanding of main duties and functions, thus requiring strengthened organizational communication and continuous capacity development. This study confirms that competency-based management and systematic development of PPPK play an important role in improving the effectiveness of task implementation in the public sector.

Based on data from FAO (Food and Agriculture Organization of The United Nations), it has been predicted that the aquaculture subsector will become one of the most relied-upon resources in the future, especially in meeting food needs, fish-based nutritional needs, and empowering the global community's economy (FAO, 2016). Catfish is a type of freshwater fish that can grow and develop well because it can be cultivated in limited land areas (Marsela, 2018). The frequency of feeding is one of the important factors that need to be considered in catfish farming. To determine the effect of different feeding frequencies on the absolute weight of dumbo catfish, a study was conducted using an experimental design called the Completely Randomized Design (CRD), with 3 treatments and a total of 8 replications. The test treatments were as follows: Treatment 1 (feeding twice a day), Treatment 2 (feeding three times a day), and Treatment 3 (feeding four times a day). The results of the ANOVA test showed a significant value of 0.000 (P < 0.05), indicating a significant difference in each of the different feeding frequencies. The analysis of the Least Significant Difference (LSD) test at a 5% significance level also showed that the relationship between each treatment had a significant value of 0.000 (P < 0.05). The average absolute weight of the fish for Treatment 1 was 12.99 grams, for Treatment 2 was 15.03 grams, and for Treatment 3 was 17.03 grams. The highest growth in the absolute weight of dumbo catfish fry occurred in Treatment 3 (feeding four times a day).

Self-confidence is an important psychological aspect that affects students' academic, social, and emotional success. Students with low self-confidence often struggle with interactions, expressing opinions, and optimizing their academic potential, which can negatively impact their personal development in school. Therefore, this issue requires attention through appropriate guidance and counseling services. This study aims to review various guidance and counseling strategies to address low self-confidence in students based on a literature review of the last six years. The method used is a library study with a traditional literature review approach, analyzing 15 national and international journal articles. The results indicate that low self-confidence is influenced by internal factors (such as negative self-concept and low self-efficacy) and external factors (such as bullying experiences and lack of social support). The impacts include decreased academic performance, social barriers, and negative emotions such as anxiety. Various guidance strategies, such as individual counseling, group counseling with sociodrama, and empathetic teacher communication, have proven effective in enhancing students' self-confidence. These findings suggest that low self-confidence is not a permanent condition but can be addressed through planned and ongoing guidance interventions. .
