By offering a structured way to integrate queuing solutions with precise programming, this research contributes to the development of more sustainable and effective service management strategies. The model therefore has significant potential for broader application in industries that rely heavily on service delivery and customer flow optimization.

The growth of vannamei shrimp is an important indicator in the success of fishery cultivation, where feeding management plays a crucial role. This study aims to determine the influence of feed management on the growth rate of vannamei shrimp and measure the contribution of these variables to growth. The research method used is a quantitative approach with the use of primary and secondary data through participatory observation at the cultivation site. Data analysis was carried out using a simple linear regression test and a determination coefficient (R²) test to answer the problem formulation empirically. The results of the regression test showed that the feed management variable had a positive effect on the Y variable (shrimp growth rate), which means that the better the feed management, the higher the growth rate of vannamei shrimp. The determination coefficient test yielded an R² value of 75.3%, indicating that feeding management made a significant contribution to shrimp growth, while 24.7% was influenced by other factors not discussed in this study. These findings confirm the importance of structured and efficient feed management in increasing shrimp farming productivity. This research is expected to be a reference for fishery business actors in designing optimal feeding strategies and encouraging further research related to other variables that also affect shrimp growth holistically.

The culinary sector continues to grow through product innovation and creative marketing strategies, supported by culinary tourism that increases tourists’ interest in tasting regional specialties. Indonesia has many potential local food resources, one of which is young jackfruit, which can be utilized as an innovative plant-based ingredient, although its use is still limited. This study aims to develop dim sum filled with young jackfruit as an innovative, healthy, and value-added product. A quantitative experimental method was used to objectively and measurably assess the quality and consumer acceptance of the dim sum. The formulation of the dim sum involved young jackfruit, eggs, tapioca flour, and wheat flour, through processes such as washing, boiling, chopping, and steaming. Sensory analysis results showed that sample B excelled in aroma, taste, and overall evaluation, while sample A had the best color, and sample C had the best texture. Some challenges identified included color changes due to oxidation, sap affecting taste, and high air content affecting texture if not properly drained. The final dim sum product had a light brown color, chewy texture, and was sensorially accepted as a high-quality dim sum with potential for further development as an innovative culinary product. These findings indicate that utilizing young jackfruit as a filling ingredient can be an attractive alternative in developing traditional processed foods with high nutritional value and consumer appeal.

Based on the results of initial interviews and observations, it was found that several students still experienced difficulties in writing procedural texts effectively. These difficulties included a lack of understanding of the structure and characteristics of procedural texts, challenges in expressing ideas in written form, limited ability to compose coherent and communicative sentences, and the use of monotonous learning models that failed to stimulate student motivation. This study aims to describe the implementation of the Project Based Learning (PjBL) model based on the Tri N approach (Niteni, Niroke, and Nambahake) to improve the procedural text writing skills of fourth-grade students at Sidomukti Elementary School, Ambal Sub-district, Kebumen Regency, as well as to identify the improvement in writing skills after its application. The research employed a descriptive qualitative method with data collection techniques including observation, tests, and documentation. Data analysis was conducted through the stages of data reduction, data display, and conclusion drawing. The findings revealed that the application of the PjBL model integrated with Tri N values significantly improved students’ ability to write procedural texts. The learning process was carried out through six main stages of PjBL: formulating essential questions, planning projects, creating schedules, monitoring student activities, testing results, and evaluating learning experiences. The integration with Tri N principles encouraged students to understand, imitate, and develop their writing skills gradually. Thus, the PjBL model based on Tri N proved effective in helping students overcome writing difficulties while also fostering creativity, independence, and active participation in the learning process.

Hypertension is an abnormal increase in blood pressure in the arteries that persists over a period of time. Hypertension is defined as an increase in systolic blood pressure of at least 140 mmHg or diastolic blood pressure of at least 90 mmHg. Symptoms experienced by people with hypertension include dizziness, irritability, ringing in the ears, difficulty sleeping, shortness of breath, heaviness in the neck, fatigue, and blurred vision. The purpose of this study was to determine the effect of warm foot baths with salt and recitation of prayers on the blood pressure of patients with hypertension. The method used is quantitative, with a pre-experimental research design using a one-group pre-test-post-test design. Hydrotherapy is performed by soaking the feet in warm water mixed with salt and reciting prayers using 3 liters of warm water at a temperature of 38-40ºC mixed with 15 grams or 3 teaspoons of salt for 15-20 minutes. In addition to warm water foot soaking therapy, it can also be combined with incorporating elements of faith, one form of which is recitation. Sampling was conducted using non-probability sampling techniques. For the sample size in this study, the researcher used the Slovin sample size formula, which is used to calculate the minimum sample size in a finite population with a total sampling approach and 16 respondents. Conclusion: Warm foot bath therapy with salt mixture and recitation has an effect on blood pressure changes in hypertensive patients.

Indonesia, as an archipelagic nation, faces considerable challenges in meeting its food requirements in accordance with Law No. 18 of 2012 on Food Security. The country’s heavy reliance on wheat imports, ranking as the largest wheat importer globally, highlights the urgency of diversifying local food sources. This study aims to explore the utilization of jali flour (Coix lacryma-jobi L.), mocaf flour (Modified Cassava Flour), and soybean flour as raw materials for producing fettucini pasta, with the addition of green spinach extract for natural coloring and nutritional enhancement. A quantitative experimental method was employed, testing three formulations of jali and mocaf flour combined with soybean flour. Sensory evaluations were conducted with 35 panelists—comprising trained, semi-trained, and untrained participants—to assess color, aroma, taste, texture, and overall acceptability. The findings revealed that flour composition significantly influenced pasta’s sensory attributes. The F2 formulation (50% jali flour, 50% mocaf flour, 20% soybean flour) achieved the highest acceptance, with average scores across all parameters rated as “liked” to “highly liked.” The incorporation of spinach extract not only imparted an appealing natural green hue but also enhanced the product’s nutritional profile, particularly in iron and dietary fiber content. These results underscore the potential of combining jali and mocaf flours as a nutritious, gluten-free pasta alternative that supports local food diversification and reduces reliance on imported wheat.

With this approach, productive waqf is expected to provide wider and sustainable benefits for the community, as well as be an inspiration for other waqf institutions in Indonesia to adopt a similar strategy.

Oil palm is a leading commodity that makes a major contribution to Indonesia’s economy, yet a significant productivity gap remains between actual and potential yields. A principal cause is suboptimal water management, which leads to flooding during the rainy season and drought in the dry season. This study develops a Conceptual Design (CD) for water management to map existing problems, analyse root causes, formulate improvement measures, and present a macro-level cost estimate for the study site. The research was conducted at an oil palm plantation in East Kalimantan anonymized as “PT XYZ.” The site was selected due to recurrent flooding and a recent change in ownership that limited data availability, making it well-suited for a CD-stage assessment. The objective is to identify water management issues and propose effective recommendations. A quantitative approach integrates primary data from field observations and measurements with secondary data. The analyses cover flood problem assessment, Water Management Zoning (WMZ/ZPA), rainfall analysis, hydrology, hydraulics, improvement proposals, and macro cost estimation. Results indicate that challenges are driven by swampy land conditions and inadequate channel and hydraulic structure capacity. Micro-watershed delineation using DEMNAS identified four ZPAs totalling 479–4,061 ha. Design rainfall was derived from CHIRPS satellite data using a log-normal distribution. Hydrologically, peak discharges range from 3.87–22.58 m³/s for the 2-year return period and 4.46–26.31 m³/s for the 5-year return period. Hydraulically, the proposed dimensions for rivers, outlet drains, carrier drains, and field-edge drains are 4×3×2 m to 9×7×3 m (T=2 years) and 4×3×2 m to 10×8×3 m (T=5 years), while collection and main drains are proposed at 3×2×2 m for both return periods. The total estimated investment for the 5-year design scenario is IDR 27,999,263,000.

The results of the study indicate strengths in the form of scarcity of tourist attractions and free entry. Weaknesses include low visitor interest, suboptimal digital marketing, and limited land. Opportunities lie in the availability of good accommodation and services, while threats include the lack of tourist attractions and the existence of certain myths or beliefs. These findings can be used as a reference in formulating development strategies to increase the interest and awareness of Situ Cilangla among the public.

This study aims to analyze the influence of using non-digital or “traditional” learning media on the learning concentration of Grade X students in Islamic Religious Education (PAI). The background of this research is based on the phenomenon of increasing student distractions caused by the use of gadgets and digital media, which often reduce focus during the learning process. Therefore, alternative learning strategies are needed by utilizing simple media that emphasize direct interaction between teachers and students. The research method used is quantitative with a survey approach through questionnaires distributed to Grade X students as respondents. The study population consists of all Grade X students at one senior high school, with the sample determined using Slovin’s formula to ensure representativeness. Data were analyzed using simple regression techniques to measure the extent of the influence of non-digital learning media on students’ concentration levels in PAI learning. The results of the study show a positive and significant effect, where non-digital learning media such as blackboards, flashcards, and simple teaching aids were proven to help increase focus, reduce distractions, and strengthen comprehension of religious subject matter. In addition, the use of traditional media encourages active student participation through discussions and hands-on activities, making the learning process more interactive. Thus, this study concludes that non-digital learning media remain relevant as effective alternatives, particularly in PAI learning for Grade X students, and can serve as a practical solution in addressing the challenges of the digital era, which is filled with potential distractions.

This research is directed to answer two main problems: the form of liability imposed on parking service providers toward consumers, and how the Supreme Court decision reflects (or diverges from) legal justice and proportionality. The study aims to examine the legal liability approach adopted in the Supreme Court Decision Number 2157/K/Pdt/2010 and to formulate an ideal concept of a fair and proportional limitation of liability for parking service operators. In the aforementioned decision, the Supreme Court held the parking operator liable for the loss of a consumer’s vehicle, even though a disclaimer clause had been clearly printed on the parking ticket. This ruling raised controversy, as it seemed to overlook the fact that the operator had fulfilled their duties to a reasonable and professional standard. The substance of parking as an object of regional tax was disregarded in the judicial consideration, which focused solely on consumer protection law. This has led to an interpretation that imposes an almost unlimited liability on the service provider. This study employs doctrinal legal research, supported by conceptual approaches in parking regulation and legal case analysis. The method used is normative legal research (doctrinal) with statutory, conceptual (regarding lease and deposit agreements), and judicial approaches. The findings indicate that parking service providers should not be subjected to absolute liability. Instead, the assessment of liability must take into account the principles of justice, proportionality, and contributory negligence. Hence, there is a need for a clear formulation of liability limitations that not only safeguard consumer rights but also consider the reasonable obligations of business actors, particularly within the context of regional tax regulations related to parking.

This research was conducted on fourth-grade students of SD Negeri 01 Karang with the aim of analyzing the effect of the implementation of the Javanese culture-based Project Based Learning (PjBL) model on students' communication skills in the 2025/2026 academic year. The research subjects were 25 students, consisting of 12 male students and 13 female students. This type of research is quantitative with a One Group Pre-Test Post-Test Design. The research procedure began with the administration of a pre-research questionnaire to determine the level of instrument validity, and the results of the validity test showed that there were 10 questionnaire items that met the valid criteria for use in data collection. Data analysis was carried out through a normality test using the One-Sample Shapiro-Wilk formula and a hypothesis test using the Paired Sample T-Test formula. The results of the analysis showed a significance value <0.000 with a probability <0.05, so it can be concluded that the research hypothesis is proven, namely there is a significant effect of the implementation of the Javanese culture-based PjBL model on improving the communication skills of fourth-grade students. These findings confirm that project-based learning linked to local cultural contexts not only improves communication skills but also helps students better understand and appreciate their local cultural values. Thus, cultural integration in the PjBL model is an effective strategy for improving the quality of learning, both academically and strengthening students' cultural identities.

The management of domestic wastewater remains a major challenge in rural areas, including in Central Tapanuli Regency. Limited community participation, low access to environmental information, and weak institutional support are key factors hindering sustainable sanitation efforts. This study aims to identify and analyze the factors influencing community roles in environmentally friendly wastewater management and to formulate empowerment strategies that align with local characteristics. This research uses a Mixed Methods approach, combining a descriptive quantitative method with multiple linear regression analysis to assess the influence of variable X1 (Knowledge), X2 (Access to Information), and X3 (Institutional Support) on variable Y (Community Role). Quantitative data were collected from 175 respondents using a closed-ended questionnaire, while qualitative data were obtained through in-depth interviews and field observations in four villages: Sipeapea, Pandan, Tapian Nauli, and Hutabalang. The results show that all three independent variables have a positive influence on enhancing community roles, with institutional support being the most dominant factor. In addition, qualitative interviews revealed a gap in practical knowledge and a need for stronger cross-sectoral communication. These findings indicate that optimizing community involvement strongly depends on continued education, information transparency, and institutional synergy. This study recommends intervention strategies including community-based sanitation education, the establishment of village environmental information systems, and the integration of waste management programs into regional development planning. These findings are expected to serve as a foundation for more adaptive, contextual, and sustainable environmental policymaking in Central Tapanuli.

The role of the Regional People's Representative Council (DPRD) Secretariat is crucial in supporting the effective supervision function of the DPRD as a pillar of good governance. However, at the Cilegon City DPRD Secretariat, this role faces significant constraints due to a policy of assigning staff to assist in work visits that is not competency-based, which risks weakening local government accountability. This research aims to analyze the facilitation role of the Cilegon City DPRD Secretariat, identify the constraints arising from the removal of expert supervision staff, and formulate optimization strategies to strengthen the institution's role. This study uses a qualitative descriptive method, with data collected through in-depth interviews with key informants within the Secretariat, observation, and document analysis. The research findings indicate that (1) the Secretariat's role has been degraded to be administrative rather than substantive; (2) the main constraint stems from a staff assignment system that ignores competence, which leads to a decline in the quality of supervision reports; and (3) there is an urgent need to reform the human resource management (HRM) system. It is concluded that the optimization of the Secretariat's role can only be achieved by reforming the staff assignment policy and implementing structured competency development programs to restore professionalism and effective support for the DPRD's supervision function. Therefore, this research recommends three strategic steps: in the short term, revising the staff assignment policy to prioritize competence; in the medium term, developing and implementing clear Competency-Based HRM Guidelines; and in the long term, organizing continuous functional training programs to enhance staff capacity in professionally and effectively supporting the DPRD's supervision function.

This study investigates the differences in customer satisfaction levels toward the services of Bank Syariah Indonesia by employing a nonparametric statistical approach. Customer satisfaction is a critical benchmark in Islamic banking, as it not only reflects the quality of services but also the extent to which sharia compliance is embedded in financial practices. Given that satisfaction data are generally ordinal and may not fulfill the assumptions of normal distribution, nonparametric methods such as the Kruskal-Wallis and Mann-Whitney tests were selected as the primary analytical tools. This research adopts a qualitative library-based method by reviewing relevant literature, scientific articles, and previous empirical studies to construct a comprehensive understanding of customer satisfaction measurement within Islamic banking. The findings highlight that variations in satisfaction are influenced by multiple factors, including service speed, staff friendliness, accessibility of digital platforms, and clarity of sharia principles applied in daily operations. Results further suggest that demographic characteristics and service usage frequency significantly shape satisfaction differences across customer groups. Theoretically, this study enriches the body of knowledge on the application of nonparametric statistics in Islamic banking research, while practically, it provides actionable insights for Bank Syariah Indonesia in formulating adaptive service strategies. These contributions are expected to assist the bank in strengthening customer loyalty, enhancing competitiveness, and sustaining growth in the dynamic modern banking industry.

Community participation in the formation of Village Regulations (Perdes) is an important indicator in realizing transparent, democratic, and responsive village governance to the needs of residents. However, in Teluk Kapuas Village, the level of community participation in the process is still relatively low. This is evident from the minimal involvement of residents and village officials in understanding the mechanisms and urgency of Perdes preparation. Based on these conditions, Community Service (PKM) activities were carried out with the aim of increasing the knowledge, understanding, and awareness of the community and village officials regarding the importance of active involvement in Perdes formation. The problems raised in this activity include: (1) the level of knowledge and understanding of village officials regarding the procedures for Perdes formation; and (2) factors that hinder the community from participating optimally. The methods used were lectures and interactive discussions involving village officials and community representatives. The results of the activities showed that the understanding of village officials and the community was still limited, so that participation in Perdes formation was not optimal. Through this PKM activity, it is hoped that there will be an increase in the understanding, awareness, and involvement of the Teluk Kapuas Village community in the Perdes formulation process so that it can produce village regulations that are more participatory and meet the needs of residents.

Sappan wood (Caesalpinia sappan L.) is known to contain various bioactive compounds such as saponins, tannins, flavonoids, phenols, brazilin, and gallic acid. These compounds play an important role as antioxidants that can ward off free radicals and absorb UVA and UVB radiation that are harmful to the skin. Ultraviolet radiation is known to accelerate premature aging and cause tissue damage, so a topical formulation is needed that can provide protection while maintaining skin health. This study aims to determine the antioxidant activity and sunscreen ability of sappan wood extract in the form of lip balm with varying extract concentrations. Antioxidant activity was evaluated using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method, while the Sun Protection Factor (SPF) value was determined by the Mansyur method using UV-Vis spectrophotometry. Sappan wood extract was formulated into four lip balm preparations, namely F0 (control without extract), F1 (5%), F2 (10%), and F3 (15%). Physical tests including homogeneity, pH, spreadability, adhesiveness, and organoleptic were conducted to ensure the quality of the preparation. The results showed that sappanwood extract had an IC50 value of 23.62 ppm which was categorized as very strong antioxidant activity. In the lip balm formulation, the IC50 values ​​obtained were F0 = 246.76 ppm (very weak), F1 = 92.68 ppm (strong), F2 = 78.03 ppm (strong), and F3 = 63.58 ppm (strong). The SPF test showed a protection value of F0 = 2.11 (minimum), F1 = 13.64 (maximum), F2 = 14.25 (maximum), and F3 = 18.28 (ultra). Thus, lip balm made from sappanwood extract has the potential as a cosmetic preparation that not only meets physical criteria, but also provides high antioxidant activity and effective sunscreen protection.
