Abstract

Industry 4.0 has shifted business processes from traditional to digital systems and forced companies to take strategic steps to become more sustainable, one of which is e-commerce technology. A key element in getting consumers to accept and be interested in using e-commerce is the availability of a user-friendly e-commerce platform. This study intended to examine how the Technology Acceptance Model (TAM) theory's application analyzes consumer acceptability and adoption of the e-commerce website. The number of users that have completed transactions on the e-commerce (Plantage.id) website between January 2021 and August 2022 serves as the population and sample in this causal quantitative study. SEM-PLS, using the software SmartPLS, is used for data analysis. The results showed a positive and significant relationship between a significant relationship website; meanwhile, the influence of perceived ease of use on attitude towards using, perceived usefulness on behavioral intention, and attitude towards using on behavioral intention showed insignificant effects. The results of this study align with the Technology Acceptance Model (TAM) theory, which states that the perceived ease of use and perceived usefulness are the main factors that are important for users in determining the acceptance and actual usage of a new information technology system such as e-commerce. The higher these two factors, the greater the chance consumers can accept and use the systems.

Abstract

This study explores the effects of government expenditure allocations in education, health, and social sectors on the Human Development Index (HDI) levels in Aceh Province, Indonesia. The Human Development Index, introduced by the United Nations Development Programme, measures a country's achievements in health (life expectancy), education (mean years of schooling and expected years of schooling), and standard of living (GNI per capita). Recognizing the pivotal role these expenditures play in enhancing community welfare, this research aims to address the critical issues of economic disparities and limited access to education and healthcare in the Babussalam District, Southeast Aceh Regency. By employing a quantitative approach and analyzing data from 314 respondents through multiple regression analysis, the findings indicate that allocations for education, health, and social programs significantly influence the HDI levels, highlighting the crucial impact of targeted government spending on improving human development outcomes. The study underscores the importance of development and empowerment programs, advocating for strategic investments in these key area to foster community welfare and development

Abstract

The role of companies as actors in production processes that utilize nature and resources is crucial. Therefore, to reduce increasing environmental degradation, companies carry out activities that are not only aimed at making profits but also pay more attention to survival, nature preservation, and socio-economic communities in the areas where they operate through corporate social responsibility (CSR). This research aims to evaluate the implementation of corporate social responsibility (CSR) programs and environmental management carried out by PT Sorik Marapi Geothermal Power (PT SMGP) and their impact on the local communities around the company's operational area. This evaluation includes the effectiveness and efficiency of the CSR programs implemented by PT SMGP, as well as the environmental management efforts undertaken. The data collection methods used are observation methods, interview methods, and documentation methods. The source of information in this research uses primary and secondary data. The research shows that, first, the company's CSR programs include relationship building, public services, and community empowerment. Second, environmental management activities carried out by the company are still not effective and efficient because many bad incidents occur, such as gas poisoning, noise, and drought.

Abstract

In the context of optimizing performance, the tourism industry has great potential as a source of income for regions and countries. One area that has great potential in the tourism industry is Rembang Regency, Central Java, Indonesia. However, this industry is also vulnerable to various risks, such as natural disasters, pandemics, and security issues. Therefore, this research aims to identify risks in the tourism industry supply chain in Rembang Regency and develop effective mitigation strategies. The research method used is decision matrix risk assessment (DMRA), which involves supply chain mapping, risk identification, risk assessment, risk response development, and risk response control. The results of identifying risks that need to be mitigated from travel agents to tourist activities include fluctuating products/services, incompatibility with tourist destinations, and failure in promotional programs. Meanwhile, stakeholder activities in the tourism industry include failure in formulating policies and promotional programs. Proposed mitigation measures include diversifying supply chains, improving communication between suppliers and the tourism industry, and developing flexible policies. Implementation of this strategy is expected to strengthen the tourism industry supply chain in Rembang Regency, improve the tourist experience, and support sustainable economic growth. Risk mitigation in the tourism industry also contributes to the performance of the tourism industry and the achievement of sustainable development goals (SDGs) by providing benefits to the environment, economy, and local communities.

Abstract

Filariasis is a serious parasitic infection caused by thread-like worms known as filariae. These worms are transmitted to humans through the bites of infected mosquitoes. The infection mainly affects the lymphatic system, which is part of your body's immune system. Poor sanitation and lack of proper housing infrastructure are a few aspects causing filariasis. This research aims to to determine the environmental factors related to the incidence of filariasis in Asahan Regency, North Sumatra Province Data was collected using a purposive sampling technique and involved direct observation of the research subjects. This data was analyzed using univariate and bivariate analysis to test the hypothesis and using numerous variables like temperature, humidity, conditions around the house that become mosquito habitat. This paper found that the majority of respondents with filariasis had non-permanent walls, ceilings, and no mosquito mesh in their homes. Houses with non-permanent walls or without mosquito mesh were found to have a higher risk of filariasis. Specifically, non-permanent walls increased the risk by 4.342 times, and the absence of mosquito mesh increased the risk by 4.848 times. The condition of the ceiling was not proven to be a risk factor for the occurrence of filariasis. The presence of mosquito mesh was found to be an effective preventive measure in reducing the risk of human contact with the filariasis vector mosquitoes.

Abstract

Fisheries management, which focuses on using fisheries resources to improve the livelihood of the fishing communities, has led to over-exploitation of fish resources on the east coast of North Sumatra. This has led to a decline in the potential of some fish species, which in turn has affected fishermen's incomes. This study aims to identify the socio-economic conditions of fishermen through the Ecosystem Approach to Fisheries Management (EAFM) and the factors that influence them. The data used are primary and secondary data, collected through observation, interviews, and literature studies. The study involved a sample of 64 fishermen from three locations along the eastern coast of Sumatra: Medan, Serdang Bedagai, and Deli Serdang. This research uses a descriptive qualitative method and the EAFM approach to analyze the social and economic conditions of fishermen in Medan, Deli Serdang, and Serdang Bedagai. The results of this study indicate that there has been a decline in the number of fishermen and the capture fisheries production at the research sites. The score of the social domain scored 55.55 (moderate), while the economic domain scored 66.67 (good) indicating effective but improvable management. The research results show that the indicators of stakeholder participation, utilization of local knowledge for fisheries management, asset ownership, and demand for fishery products are in the good category, while the indicators of fisheries conflicts and fishermen's household income are in the poor category, which needed to be the focus for improvement and enhancement.

Abstract

Medan City, the third-largest city in Indonesia, faces significant challenges in managing its public green open spaces (RTH) due to high population density, rapid urbanization, and insufficient green space, which falls far short of the 30% mandated by law. This research assesses the management of public green spaces in Medan through a SWOT analysis, revealing internal strengths such as a Regional Spatial Plan and government commitment, alongside weaknesses like suboptimal management, lack of coordination between agencies, and inadequate regulations. External factors, including opportunities from NGO funding and potential land acquisition, contrast with threats like rapid population growth and misuse of green spaces. Through data collection methods, including focus group discussions, questionnaires, and interviews with key stakeholders, the research identified key areas for improvement in green space management. Strategic recommendations include strengthening policies, increasing public awareness, optimizing cross-sector collaboration, and promoting sustainable urban planning. Additionally, leveraging green spaces for economic growth through multifunctional uses can enhance their value to the community. This study concludes that public green open spaces in Medan City can contribute significantly to sustainable urban development and environmental balance if managed more effectively, with better coordination, stronger regulations, and resource allocation. The findings aim to provide valuable insights for urban planners and policy makers in achieving urban sustainability goals.

Abstract

Poncan Gadang Island is one of the islands in Sibolga City. The island is utilized by the community for various activities, such as beach tourism, underwater tourism and capture fisheries. This study aims to assess the coral reef condition of Poncan Gadang Island and provide recommendations for its management efforts. The research was conducted in February 2023 using the Underwater Photo Transect method to assess coral cover. The Underwater Photo Transect method was selected for its ability to provide permanent photographic records for further analysis, comparison over time and efficiency in capturing large- scale coral conditions. Management recommendations were analyzed using the SWOT analysis method. SWOT analysis was selected because provided a structured framework for management decision-making. The results indicated that the average percentage of live coral cover was 24.01%, classifying the coral reefs as damaged condition. This degradation is likely influenced by anthropogenic activities and environmental stressors. Based on the SWOT analysis, it is recommended that Poncan Gadang Island’s management address internal weakness to mitigate external threats. The SWOT analysis shows that management efforts should focus on addressing internal weaknesses, such as inadequate of local awareness and conservation policies to counteract external threats like unsustainable tourism practices and climate change. Implementing stricter tourism regulations, community- based conservation efforts and coral reef restoration for enhance reef resilience.

Abstract

The study analyzed the spatial distribution of lead (Pb) and cadmium (Cd) in well water around the Terjun Landfill in Medan City. The research aimed to determine Pb and Cd concentrations in dug and drilled wells, compare their levels, and assess the impact of proximity to the landfill's active zone. A total of 22 wells located 50–500 meters from the landfill were sampled using purposive sampling. Spatial analysis was conducted using GPS, while differences in Pb and Cd levels between well types were analyzed using a t-test (α = 0.05, CI 95%). Results showed that Pb concentrations in dug wells ranged from 0.0039 to 0.0379 mg/L, with the highest levels found near SG1 and SG4, indicating landfill influence. In contrast, Pb levels in drilled wells were lower (<0.0001 to 0.0158 mg/L) and primarily influenced by external sources. Cd concentrations ranged from 0.0008 to 0.0032 mg/L in dug wells and 0.0005 to 0.0102 mg/L in drilled wells, with contamination in drilled wells linked to external activities. Proximity to the landfill significantly affected Pb levels in dug wells but had no impact on drilled wells, while Cd levels were unaffected by distance in both well types. The findings suggest that transitioning from dug wells to drilled wells is essential to reduce heavy metal exposure and ensure safer water quality for residents.
