Abstract

This study aims to analyze and compare the accuracy of the Double Moving Average (DMA) and Single Exponential Smoothing (SES) methods in forecasting the demand for fancy goldfish at the Wirajaya MSME. A descriptive-comparative quantitative approach was employed, utilizing historical monthly demand data for Ranchu, Oranda, and Lionhead goldfish from January to December 2025. The DMA method was tested using periods of n = 2, 3, and 4, while the SES method utilized smoothing parameters ranging from α = 0.1 to 0.9. Method accuracy was evaluated based on Mean Absolute Deviation (MAD), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE). The results indicate that DMA yielded MAPE values ​​of 5.97% for Ranchu, 4.91% for Oranda, and 6.47% for Lionhead. In contrast, SES produced MAPE values ​​of 10.33% for Ranchu (at α = 0.4), 7.58% for Oranda (at α = 0.5), and 10.14% for Lionhead (at α = 0.7). The comparison reveals that DMA achieved lower MAPE values ​​than SES across all three fish varieties. Consequently, DMA demonstrates superior forecasting accuracy and serves as a viable alternative for supporting production planning and inventory control of fancy goldfish at the Wirajaya MSME.

Abstract

This study aims to analyze the proportion of productive and non-productive work time among the workforce, identify non-productive activities, and formulate proposals for productivity improvement at the Sumber Teknik Workshop in Prigi Village, Watulimo District, Trenggalek Regency. The study employs a quantitative descriptive approach using the Work Sampling method—observing workforce activities at random intervals to determine the proportions of productive and non-productive work. Observations were conducted on two welding operators, totaling 834 observations, and the data were analyzed using Microsoft Excel. The results indicate that Operator 1 engaged in productive activities 73.73% of the time and non-productive activities 26.27% of the time, while Operator 2 recorded figures of 74.22% and 25.78%, respectively. Overall, the average productive activity was 73.98%, and non-productive activity was 26.02%. Non-productive activities included searching for tools, waiting for instructions and materials, waiting for a turn to use tools, running out of electrodes, equipment malfunctions, and rework due to errors. These results suggest that workforce productivity is reasonably good; however, there remains room for improvement through better tool organization, material management, and equipment maintenance

Abstract

This study aims to analyze the effect of price and facilities on customer satisfaction at Kedai Sali Bandung Tulungagung. The research employed a quantitative approach with an associative design. Data were collected through questionnaires distributed to 67 customers selected using purposive sampling. The data were analyzed using the Partial Least Square-Structural Equation Modeling (PLS-SEM) method with SmartPLS 4 software. The results indicate that all indicators met the validity and reliability requirements. The R-Square value of 0.582 shows that price and facilities explain 58.2% of customer satisfaction, while the remaining 41.8% is influenced by other factors outside the scope of this study. Hypothesis testing revealed that price had a positive but insignificant effect on customer satisfaction (T-statistic = 1.445; P-value = 0.149). In contrast, facilities had a positive and significant effect on customer satisfaction (T-statistic = 4.361; P-value = 0.000). The study concludes that facilities play a more important role than price in enhancing customer satisfaction. Therefore, Kedai Sali management is encouraged to continuously improve the quality of its facilities to provide a better customer experience and increase customer satisfaction

Abstract

Nickel is a crucial mineral commodity in the manufacturing industry and the global energy transition, particularly as a raw material for electric vehicles. The volatility of nickel prices creates a need for forecasting methods capable of generating accurate price estimates. This study aims to analyze and compare the accuracy of three time-series forecasting methods—Double Exponential Smoothing (DES), Quadratic Trend, and Exponential Trend—in projecting nickel prices. The research uses a quantitative approach with 30 observations of monthly nickel price data for the period January 2022 to June 2024 obtained from the public, namely Investing.com and related publications. The accuracy of each method was evaluated using Mean Absolute Deviation (MAD), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE). The results indicate that the Double Exponential Smoothing method achieved the highest accuracy, with a MAPE of 8.45%, whereas the Quadratic Trend and Exponential Trend methods yielded MAPE values ​​of 11.47% and 11.89%, respectively. Based on the best-performing method, the projected nickel price for July 2024 is 20,423.40 USD/dmt. This study contributes an empirical comparison of the effectiveness of these three forecasting methods regarding fluctuating monthly nickel price data and provides a basis for selecting more accurate forecasting methods to support planning and decision-making related to nickel prices.

Abstract

Rural poverty remains a challenge for economic development; consequently, strengthening village economic institutions—such as Village-Owned Enterprises (BUMDes)—is crucial for optimizing local potential. This study aims to analyze the role of BUMDes Alam Depati Payung in local economic development in Rantau Kermas Village. A qualitative approach utilizing a case study method was employed. Data were gathered through in-depth interviews, observation, and documentation, then analyzed descriptively through the stages of data reduction, data presentation, and conclusion drawing. The results indicate that BUMDes Alam Depati Payung plays a role in local economic development by leveraging village assets, including tourism sites, customary forest management, the Serampas Coffee farming business, and a micro-hydro power plant (PLTMH). These business units contribute to community economic activity and the provision of services to meet village needs. However, several units have experienced performance declines due to management, administrative, financial, and organizational challenges—most notably the Serampas Coffee farming business, which ceased operations in 2023. These findings demonstrate that the sustainability of the BUMDes' role in local economic development depends not only on business potential but also on strengthening governance and institutional management capacity.

Abstract

Turmeric farming serves as a source of income for farmers in Solok City; however, its sustainability faces various production constraints and limited input support. This study aims to analyze the financial feasibility of turmeric farming and its contribution to farmers' household income in Solok City. A quantitative descriptive approach utilizing a farm analysis model was employed. Data were collected from 31 active turmeric farmers in the Payo area (Tanah Garam Urban Village, Lubuk Sikarah District) through structured interviews, observation, and documentation. The analysis covered production costs, revenue, income, the R/C ratio, financial viability, and the contribution of farming income to household income. The results indicate that turmeric farming is financially profitable, with an R/C ratio of 2.27 and an average net income of IDR 30,744,279 per planting season. However, the farming operation is not yet financially viable, as revenue fails to cover the combined total production costs and household consumption expenditures, resulting in an average deficit of IDR 353,401. Turmeric farming income contributes 54.72% to the farmers' household income, placing it in the moderate category. These findings suggest that while turmeric farming is financially profitable, its sustainability requires strengthening through the provision of high-quality planting material, improved production efficiency, enhanced farmer bargaining power, and the diversification of household income sources.

Abstract

Rape is a form of sexual violence that inflicts physical, psychological, social, and legal consequences upon the victim. The situation becomes increasingly complex when the perpetrator is a law enforcement officer—someone duty-bound to protect the public. This study aims to analyze the legal provisions and elements of the crime of rape as stipulated in Law Number 1 of 2023 concerning the Criminal Code (KUHP), as well as the legal protections afforded to victims of rape committed by police officers. The research employs a normative-juridical method, utilizing statutory, conceptual, and case-based approaches. Legal materials—comprising primary, secondary, and tertiary sources—were analyzed qualitatively. The findings indicate that the actions of the perpetrators in the rape case involving a female police recruit in Jambi met the elements of the crime of rape as defined in Article 473 of the National Criminal Code. In addition to criminal liability, the perpetrators may also face ethical accountability under Police Regulation Number 7 of 2022. Legal protection for the victim is provided through Law Number 12 of 2022 concerning the Crime of Sexual Violence and Law Number 31 of 2014 concerning the Protection of Witnesses and Victims, encompassing rights to protection, assistance, rehabilitation, and restitution. Law enforcement action against the perpetrators must be accompanied by the comprehensive restoration of the victim's rights to ensure justice and legal certainty.

Abstract

Competition among schools—particularly private ones—increasingly drives educational institutions to build a positive image and enhance service quality to gain public trust and influence prospective students' enrollment decisions. In this context, word-of-mouth serves as a crucial mechanism, as experiences and recommendations from current students and social circles shape prospective students' perceptions of the school. This study aims to examine a model regarding the influence of school image and service quality on the decision to choose a school, with word-of-mouth acting as an intervening variable. The study employs explanatory research with a quantitative approach, focusing on 10th-grade students at SMK Telkom Malang during the 2025/2026 academic year. A sample of 222 students was selected using purposive sampling. Data were collected via Google Forms in April 2026 and analyzed using Partial Least Squares (PLS) with SmartPLS software. The results indicate that school image and service quality have a positive and significant impact on word-of-mouth. School image has a positive and significant effect on the enrollment decision, whereas service quality has a positive but non-significant effect. Word-of-mouth was found to function as an intervening variable within the research model.

Abstract

This study aims to analyze the framing of Israel—or the Children of Israel (Bani Israil)—in Felix Siauw’s da'wah (Islamic outreach) communication, as well as the communication strategies employed in episodes 7 and 8 of the "Reconnect With Qur'an" series on the YNTV YouTube channel. The research adopts a descriptive qualitative approach utilizing Robert N. Entman’s framing analysis method, which encompasses four elements: defining problems, diagnosing causes, making moral judgments, and recommending solutions. Primary data consists of the da'wah videos, while secondary data was gathered from relevant books, journals, and prior studies. The analysis involved transcribing and identifying narratives concerning the Children of Israel, categorizing them according to the four framing elements, and interpreting the constructed problem, causes, moral assessment, and recommended resolution. The findings reveal that Felix Siauw frames the Children of Israel as a people who deviated from the right path due to disobedience toward God’s commands, arrogance, the misuse of intellect, and the rejection of divine revelation. Moral judgments regarding these behaviors are reinforced through Quranic narratives, while the audience is encouraged to derive lessons (ibrah) and adopt the Qur'an as a guide for life. His da'wah strategies include Quranic storytelling, the use of scriptural evidence, persuasive language, a firm tone of voice, and supporting visual and audio elements
