This study aims to forecast beef prices in Palembang City and at the national level in Indonesia using the Autoregressive Integrated Moving Average (ARIMA) method. The data used are the monthly average beef prices for the period January 2019 to December 2024. The analysis involves stationarity tests using Augmented Dickey-Fuller (ADF), model identification through Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF) plots, parameter estimation with Maximum Likelihood Estimation (MLE), and residual diagnostics with the Ljung-Box and Jarque-Bera tests. The results show that beef prices at both regional levels are not stationary at the level but become stationary after the first differencing (I(1)). The best ARIMA models obtained are ARIMA(0,1,1) for Palembang City and ARIMA(1,1,0) for the national level. Both models successfully predict price fluctuations with a low error rate and show a moderate price increase trend. These findings provide practical implications for price stabilization policy making and beef-related business planning. The forecast results state that beef prices in Palembang City and nationally are predicted to tend to rise in 2025 from January to December.  

This study aims to analyze variations in flood inundation heights in Medan City through 2024 using a quantitative approach based on Geographic Information Systems (GIS). The data used include field surveys, flood hazard maps, rainfall data, land use, and regional topography. The results show that flood heights vary between 0 and 100 cm, with distribution influenced by a combination of rainfall intensity, land use changes, drainage capacity, and topographic characteristics. The northern area of ​​the city has the highest flood heights and risk, driven by low elevation, inadequate drainage systems, and proximity to the coast and major rivers. This study emphasizes the importance of drainage management, river normalization, and spatial utilization control as effective and sustainable flood mitigation measures in Medan City. The findings of this study recommend improvements to the drainage system, river normalization, spatial utilization control, and the use of spatial data as a basis for more effective and sustainable flood mitigation planning in Medan City.

This study aims to analyze the effect of government expenditure and Regional Own-Source Revenue (PAD) on the Gross Regional Domestic Product (GRDP) of Surabaya City during the period 2014–2022. The background of the study stems from the crucial role of regional fiscal policy in promoting economic growth and the observed mismatch between the increase in regional expenditure and PAD with the development of GRDP. The research employs a quantitative approach using multiple linear regression analysis based on time-series data obtained from BPS and DJPK. The findings show that government expenditure and PAD simultaneously have a significant effect on GRDP. Partially, government expenditure has a positive and significant effect, while PAD has a positive but not significant effect on GRDP. The coefficient of determination (R²) value of 0.998 indicates that both variables can explain most of the variation in GRDP. These results confirm that government expenditure is the dominant fiscal instrument in driving economic growth in Surabaya, while the contribution of PAD still needs to be strengthened to effectively enhance fiscal capacity and stimulate productive economic activities. This study is expected to serve as a reference for local governments in formulating more targeted budget policies

The main issues identified in this study include mistargeting of beneficiaries, weak inter-agency coordination, low community participation in the verification process, and a tendency among recipients to rely on cash assistance in a consumptive manner. This research analyzes the scenario planning of the Cash Transfer Program (BLT) in reducing poverty in Surabaya City, particularly in Krembangan District. The program is implemented based on Surabaya Mayor Regulation Number 130 of 2023, which serves as the legal foundation for the regional BLT scheme. Using the Scenario Planning TAIDA model (Tracking, Analysing, Imaging, Deciding, and Acting) by Mats Lindgren and Bandhold (2003) as the analytical framework, this study examines the extent to which planning, decision-making, and implementation processes are able to respond to the socio-economic dynamics of the community. Employing a descriptive qualitative method, data were collected through interviews, observations, and documentation. The findings indicate that BLT plays a significant role in supporting low-income households and reducing poverty rates; however, challenges persist, including limited community engagement, weak inter-agency coordination, and non-productive use of assistance. The scenario planning approach is considered effective in helping the government design more adaptive, participatory, and sustainable policy strategies. It is expected that the BLT program will not only serve as a short-term intervention but also become a strategic instrument in promoting independence and improving the welfare of poor communities in Surabaya.

Abstract. This study aims to determine the effect of Good Governance and Fund Management on Public Trust in the City of Surabaya, especially in the Kemayoran Village community. This study uses a quantitative method with an explanatory approach, where data are obtained through distributing questionnaires to 100 respondents who have interacted with public services. Data analysis was conducted using multiple linear regression with the help of SPSS software. The results of the study indicate that Good Governance and Fund Management simultaneously have a significant effect on Public Trust, as evidenced by the results of the F test with a significance value of <0.05. Partially, the Fund Management variable has a positive and significant effect on Public Trust, while the Good Governance variable has a positive but insignificant effect. The coefficient of determination (R²) value of 0.658 indicates that 65.8% of the variation in Public Trust is explained by these two variables. This finding indicates that transparency and accountability in public budget management are dominant factors in increasing public trust, while the implementation of Good Governance principles has not been fully perceived as effective by the public. Thus, optimizing the quality of fund management is an important strategy to strengthen government legitimacy in the eyes of the public.

This research aims to explore the role of service excellence in enhancing consumer loyalty in culinary MSMEs, with a case study at RM Kamang Jaya in Medan City. In facing intense competition in the food industry, excellent service becomes an important strategy to maintain and expand the customer base. A qualitative approach with a case study method was employed to deeply examine customer experiences, perceptions, and service practices through interviews, observations, and documentation. The findings show that the consistent application of service standards, friendly attitudes of staff, and attention to detail in service delivery greatly contribute to customer satisfaction and loyalty. Good service has been proven to encourage repeat orders, create positive experiences, and enhance word-of-mouth promotion. Despite some technical obstacles, such as order errors or menu limitations, the quick response and professional attitude of employees were able to minimize their impact. These findings confirm that service excellence not only meets the functional needs of consumers but also builds emotional attachment, which becomes the foundation of long-term loyalty. The implications of this research are significant for other MSME actors in designing superior service strategies to face increasingly complex business competition.

The floods that struck Medan City between late November and early December 2025 significantly affected the psychosocial wellbeing of children aged 4–7 years living in evacuation shelters. Children in this developmental stage are highly vulnerable to stress, anxiety, and behavioral changes following disaster exposure. This community service program aimed to implement an Integrated Psychosocial Support Model designed to promote emotional recovery among children and strengthen the capacities of parents and shelter facilitators. The methods included play-based psychosocial activities, safe digital literacy education, parental engagement sessions, and capacity-building for local volunteers. The intervention was conducted at two evacuation shelters in Medan Labuhan and Belawan, involving approximately 220 children. The results demonstrated substantial improvements in adaptive behavior indicators—group participation, ability to follow instructions, positive emotional expression, and peer interaction—with an average increase of 1.25 points. Social transformations also emerged, including the establishment of child-friendly spaces, enhanced supportive parenting practices, and the rise of local leaders within the community. These findings indicate that integrated psychosocial support is an effective approach for post-disaster child recovery and can be replicated in similar humanitarian settings.

Data analysis was conducted using classical assumption tests and multiple linear regression to examine the relationships between variables. The results indicate that both partially and simultaneously, workload and work environment have a positive and significant effect on employee performance. Therefore, the company should pay greater attention to workload balance and create a safe, comfortable, and supportive work environment to improve employee performance and loyalty.

The growth in the number of vehicles in Surabaya has led to increased traffic congestion, particularly on the Perak Timur–Perak Barat road section, which serves as a major distribution route to the port and industrial areas. Problems arise at U-Turn points, where vehicle accumulation hampers traffic flow. This study analyzes traffic volume, travel time, queue length, and queue ratio at two U-Turn points on this section. The method used was a field survey with direct observation of vehicle volume every 15 minutes, vehicle classification, and queue length. Traffic volume was calculated using the Passenger Car Equivalent (PCE) factor based on the 1997 MKJI standards. The study results show that at Point 1, east–west direction, the highest queue ratio occurred on Tuesday from 11:00 to 12:00 (p = 4.84), while the lowest was on Sunday from 06:00 to 07:00 (p = 0.21). At Point 2, west–east direction, the highest queue ratio occurred on Tuesday from 08:00 to 09:00 (p = 6.18), and the lowest from 06:00 to 07:00 (p = 0.41). These findings indicate that during peak hours, traffic congestion increases (p > 1), causing long queues, particularly in the west–east direction in the morning. The performance of the U-Turn on the Perak Timur–Perak Barat road section needs improvement, with recommendations such as temporarily closing U-Turns during high volumes, providing alternative U-Turn lanes, and adding signs to minimize the potential for vehicle conflicts.

The validity of findings was strengthened through data source triangulation and member checks with key informants. The results indicate that the marketing and promotional strategies implemented have positively influenced the improvement of the business image and customer loyalty, although the SME still faces limitations in resources and market competition challenges. These findings provide important implications for the development of sustainable business strategies for SMEs in the culinary sector.

This study aims to analyze the capital market reaction to the groundbreaking event of the new capital city (IKN) on the stock prices of property and construction sector companies listed on the Indonesia Stock Exchange (IDX). This research employs a quantitative approach using the event study method with an observation period of 11 days, consisting of 5 days before (t-5), the event day (t), and 5 days after (t+5) the event. The sample includes property and construction sector companies that were actively traded during the observation period. Data analysis was conducted using the Paired Sample t-test through SPSS to examine differences in Abnormal Return (AR), Cumulative Abnormal Return (CAR), and Trading Volume Activity (TVA) before and after the event. The results show that there is no significant difference in AR and TVA, but there is a significant difference in CAR, indicating that the market reacted cumulatively to the groundbreaking IKN information. These findings support the semi-strong form of market efficiency theory, suggesting that the market requires time to fully reflect information into stock prices.
