Abstract

Business competition in the restaurant sector continues to experience quite rapid development, which means businesspeople have to be careful when making decisions. Therefore, the purpose of this study is to find out and analyze the influence of raw material quality, product quality, and price on purchasing decisions with competitive advantage as an intervening variable in Silungkang Restaurant. The sample of this study is 100 consumers of the Silungkang Restaurant. The model of this research is structural equation modeling (SEM), with an analysis tool using SmartPLS 3. The findings of this study show that raw material quality, product quality, and competitive advantage have a positive and significant influence on purchasing decisions. In addition, it was also found that the quality of raw materials, product quality, and price had a positive and significant effect on competitive advantage. Meanwhile, price has an effect, but significantly, on the purchase decision. For the indirect influence through the competitive advantage variable, it was found that competitive advantage could not play a role in strengthening the influence of price on purchasing decisions. However, indirect influence through competitive advantage variables, a significant influence was found on the quality of raw materials and product quality on purchasing decisions.

Abstract

Ternate Island is part of the administrative area of Ternate City, North Maluku Province which was once the capital of the province and the center of government continues to experience physical development. This study aims to analyze the development of urban growth in Ternate Island in the period 2004-2032. The cellular automata markov chain method uses 2004, 2014 and 2024 land cover data and driving factors consisting of elevation, slope, distance from road and distance from POI to predict urban growth. The results of the analysis show that the urban area continues to increase in area, namely in 2004 the urban area had an area of 1,424.14 ha, 2014 an area of 1,728.45 ha and in 2024 an area of 2,010.78. The prediction results of urban growth on Ternate Island in 2032 show that the urban area has an area of 2,884.37 ha. Based on the research results from the application of the markov chain cellular automata method, it is hoped that these findings can be taken into consideration in designing a sustainable spatial arrangement of Ternate City. So that ecological balance, environmental balance and food security can be maintained and meet the requirements of a city that has the carrying capacity and environmental capacity.

Abstract

This study aims to analyze the role of Quality Education in forming a generation of young leaders through Basic Student Leadership Training (LDKS) implemented in the Asriloka Wonosalam Ecotourism Area. Using the Systematic Literature Review (SLR) method with a comparative qualitative descriptive approach, this research examines various literatures related to leadership education, ecotourism, and sustainable development. The results show that the integration of the Quality Education concept in ecotourism-based LDKS contributes significantly to building adaptive, innovative and sustainability-oriented leadership characters. LDKS participants gain direct leadership experience through experiential learning, which includes managerial skills, decision making, problem solving, and social and environmental awareness. In addition, the ecotourism area provides a supportive learning environment, where participants can develop conservation-based leadership skills, green entrepreneurship, and community empowerment. The implication of this study confirms that the ecotourism-based LDKS approach can be an effective alternative education model in producing young leaders who are not only smart and competitive, but also have high concern for the environment and society. Therefore, it is necessary to strengthen the curriculum, increase collaboration between educational institutions, ecotourism managers, and local communities, as well as continuous evaluation to ensure the effectiveness of the program in the long term.

Abstract

In this study, spatial and temporal trends of Land Use and Land Cover Change (LULCC) in Choke Mountain, Ethiopia, between 2013 and 2023 were explored employing a mixed-methods approach. Satellite imagery (Landsat 8 OLI/TIRS) was analyzed through supervised classification and post-classification change detection techniques, supported by field observations, key informant interviews, and focus group discussions. The results reveal extreme changes: agricultural land raised by 4.5% (1,207.95 ha), predominantly at the expense of grasslands (−11.9%) and shrublands (−34.8%). Forest cover unexpectedly raised by 28.6% (1,156.26 ha) due to Eucalyptus plantations, while natural forest decline persists. Settlement areas raised by 133%, which reflects heavy urbanization. Slope analysis revealed that 67.4% of the area is composed of gentle slopes (<30%), and 32.6% is composed of steep slopes that are susceptible to erosion. The main drivers of these changes are population growth, agricultural expansion, fuelwood requirements, and unsustainable land-use policies. These changes have deep implications for ecosystem services, soil conservation, and climate resilience in this critical Upper Blue Nile Basin region. The study recommends that integrated land-use planning, forest conservation programs, and sustainable agriculture practices are required to balance ecological integrity with livelihood needs. These findings constitute the scientific basis on which policymakers can base policies to facilitate sustainable land management in the highland ecosystems of Ethiopia.

Abstract

Rapid urbanization in Banjarmasin City has intensified domestic waste management challenges, posing a significant obstacle to achieving Sustainable Development Goals (SDGs), particularly those related to urban environmental governance. Despite the enactment of Regional Regulation No. 21/2011 promoting the 3R (Reduce, Reuse, Recycle) principles, its implementation remains fragmented and has failed to engage comprehensive community participation. This study adopts a political ecology framework to critically assess the effectiveness of the policy, emphasizing structural barriers such as institutional fragmentation, limited technological adoption, and imbalanced stakeholder power relations. A qualitative case study approach involved in-depth interviews with key stakeholders, document analysis, and field observations. Thematic analysis and triangulation methods were used to validate findings. Results indicate Banjarmasin's waste governance remains largely technocratic and top-down, with inadequate grassroots integration and weak inter-agency coordination. Technological innovations such as digital monitoring and Waste-to-Energy solutions are notably absent, further limiting policy outcomes. This study highlights the urgency of reforming local waste governance through participatory, equitable, and technologically adaptive strategies, particularly for medium-sized cities in the Global South.

Abstract

This study analyzes the role of administrative staff in enhancing the effectiveness of the Hospital Management Information System (SIMRS) in recording the daily census of patients under the Health Service Guarantee (JPPK) at Hospital X. Employing a case study design with qualitative and quantitative methods, data were collected through observations and document analysis of census reports from January to March 2025. Results indicate a significant correlation between the accuracy, competence, and compliance of administrative staff and the effectiveness of SIMRS. An error rate of 2.96% was found, primarily caused by inaccurate input of consulting doctor data, medical procedures, and medication details. Medication changes were often due to stock limitations, requiring substitutions and approval from patients, which in turn demanded timely adjustments by staff. Errors in medication pricing occurred due to delays in updating price information in the SIMRS system. These issues point to a broader problem of limited coordination and delayed information flow between hospital units. The findings underscore the importance of administrative staff with adequate knowledge and skills in using SIMRS. Their performance significantly impacts the accuracy and efficiency of JPPK patient census recording, highlighting their strategic role in supporting integrated hospital information systems.

Abstract

This study aims to analyze the patient registration flow at the Eye Clinic of Dustira Hospital Cimahi, with a particular focus on the efficiency of service and the level of patient satisfaction. The background of this research lies in the increasing demand for quality and efficient healthcare services, especially in specialized outpatient clinics that serve high volumes of patients daily. The research was conducted using a qualitative descriptive method during the Field Work Practice (PKL) period, with data collection techniques consisting of direct observation of the registration process and semi-structured interviews with both administrative staff and patients. The findings show that the registration flow at the Eye Clinic has been arranged in a systematic manner, starting from the arrival of patients, queue number retrieval, identity verification, and input into the hospital information system. However, several issues were identified, such as long waiting times during peak hours and limited patient understanding of the available digital or online registration options. These factors were found to affect overall patient satisfaction. Despite the use of a structured system, the effectiveness of the registration process still depends on patient awareness and digital literacy. Therefore, the study recommends regular evaluation of the service workflow and the implementation of patient education programs regarding the use of digital registration tools. Improvements in communication, guidance signage, and staff support can further enhance service efficiency and ensure that patients receive timely and satisfactory care at the Eye Clinic.
