Abstract

This study aims to analyze in depth the influence of brand image and promotion on purchase decisions on the Shopee e-commerce platform, focusing on Nurul Jadid University students. The background of the research is based on the rapid growth of e-commerce in Indonesia and the increasing competitiveness between digital platforms, where brand image and promotion are strategic factors in influencing consumers. The approach used is quantitative associative with the survey method through the distribution of online questionnaires. The research population was 4,762 students with a sample of 369 respondents, using the proportionate stratified random sampling technique. The research instruments were tested for validity and reliability with satisfactory results (r-count > r-table and Cronbach's Alpha > 0.7). Data analysis was carried out using multiple linear regression, F test, t test, and classical assumption test. The results showed that brand image and promotion simultaneously had a significant effect on purchasing decisions (F-count = 158,132; Sig = 0.000). Partially, brand image had a positive effect with a regression coefficient value of 0.337 (t-count = 6.674), while promotion had a significant effect with a regression coefficient of 0.283 (t-count = 8.736). The value of the determination coefficient (R²) of 0.464 indicates that 46.4% of the variation in purchasing decisions can be explained by both variables, while the rest is influenced by other factors. These findings confirm the power of a positive brand image, combined with innovative promotional strategies such as discounts, free shipping, interactive campaigns, and the use of influencers, to encourage consumers, especially students, to make purchasing decisions. The practical implications of this study indicate that Shopee and other digital business actors need to strengthen positive brand perceptions and increase the effectiveness of promotions to win competition in the digital era.

Abstract

Thermal comfort in worship spaces is an important aspect that affects the quality of religious activities. However, intermittently occupied worship spaces, such as mosques during Jummah prayers, often experience spikes in heat load due to the accumulation of sensible and latent heat from occupants and solar radiation. This study aims to analyze the actual cooling load and determine the cooling load required to achieve a comfortable room temperature based on the Cooling Load Temperature Difference (CLTD) method. Temperature measurements were taken using data loggers at one outdoor point and nine indoor points during five Fridays between October 10 and November 7, 2025, from 11:00 a.m. to 1:00 p.m. Western Indonesian Time. Cooling load calculations were based on occupancy variations of 100, 300, and 600 people and comfort temperature targets of 23°C, 25°C, and 27°C. The results showed that the temperature in the worship hall was well above the thermal comfort limit. The actual cooling load increased significantly between 12:00 p.m. and 1:00 p.m. WIB and during peak occupancy, reaching a peak load of 570,116.3 Btu/h. To achieve a comfortable room temperature, the cooling capacity needs to be increased by 8–35%. The final capacity recommendation based on the measurements and ASHRAE standards ranges from 44–69 TR. It can be concluded that the cooling system of Al-Furqon Mosque is currently under capacity and requires increased capacity and adaptive operational strategies to achieve thermal comfort in intermittently occupied worship spaces in a tropical climate.

Abstract

The rapid development of digital technology has encouraged culinary businesses to adopt online food delivery platforms, particularly GoFood, to expand market reach and improve customer service. However, the effectiveness of such platforms depends on operational capacity and alignment with local consumer preferences regarding price, convenience, and practicality. This study analyzed the implementation of digital marketing strategies through GoFood in improving community purchasing power at Cafe Raluna, Paiton District, Probolinggo Regency. A qualitative descriptive design was employed. Data were collected through observation, in-depth interviews, and documentation involving four informants: the manager, cashier, and an employee of Cafe Raluna, as well as a consumer who had previously ordered through GoFood. The data were analyzed using an interactive model comprising data reduction, data display, and conclusion drawing. The findings indicate that Cafe Raluna’s use of GoFood incorporates the four elements of the marketing mix—product, price, place, and promotion. Nevertheless, the promotional features and menu presentation have not been managed through systematic planning, thereby limiting digital marketing performance. GoFood contributes to increased community purchasing activity by providing convenient services, practical ordering processes, and promotional programs that encourage purchases. However, the magnitude of this contribution could not be determined because GoFood sales were not recorded separately from direct sales. Additional constraints included limited driver availability, platform commission fees, and competition among culinary businesses. The study concludes that GoFood supports Cafe Raluna’s digital marketing and community purchasing power, although more systematic planning, separate sales recording, and optimized promotional and menu-management strategies are required to achieve sustainable outcomes. These findings provide practical implications for small culinary businesses seeking to improve the effectiveness of platform-based digital marketing.

Abstract

Indonesia's dependence on fossil fuels, especially coal, causes greenhouse gas (GHG) emissions that have a significant impact on global climate change. As an energy transition solution, biomass is offered through co-firing technology at the energy industry's Steam Power Plants (PLTU). This study aims to analyze the sustainability of the use of biomass, especially sawdust, as an alternative fuel to replace some coal in the power generation sector. The Life CycleAssessment (LCA) approach is used to assess the environmental impact of the entire biomass life cycle, starting from the process of extracting raw materials, producing and drying sawdust, transportation to coal-fired power plants, to the combustion and residue disposal stages. The analysis was carried out using SimaPro software by considering various categories of environmental impacts, such as potential global warming (GWP), eutrophication, acidification, and depletion of natural resources. The results show that the use of sawdust biomass through co-firing has the potential to significantly reduce GHG emissions compared to the burning of pure coal, supports the Nationally DeterminedContribution (NDC) target, and contributes to the achievement of Sustainable Development Goals (SDG) 7 (Clean and Affordable Energy) and SDG 13 (Action on Climate Change).
