The background of this article is an effort to reduce the environmental impact of the Crumb Rubber SIR production process, which produces liquid and solid waste and requires high energy consumption. This study aims to identify and analyze critical aspects of the production process that contribute to environmental and energy efficiency problems. The mass balance method is used to analyze mass and energy balance in the production process. This paper examines in detail each stage of production, identifies areas where waste is generated, and measures energy consumption at each stage. The results of the study show that there are several critical points in the production process that are responsible for the production of waste and high energy consumption. This analysis helps in suggesting several process and waste management improvements to reduce environmental impact. The results of this study emphasize the need for improvements in SIR Crumb Rubber production methods to reduce and utilize waste. The energy potential that can be utilized in the closed production process in producing crumb rubber is producing biogas as an energy fuel of 56.37 KwH which is obtained from processing 1 ton of rubber raw materials into crumb rubber. This article contributes knowledge to crumb rubber producers in implementing sustainable production operational practices.</p> 2024-06-21T00:00:00+00:00 Copyright (c) 2024 UJoST- Universal Journal of Science and Technology http://ujost.org/index.php/journal/article/view/154 The Impact of Digital Access and Literacy on Women's E-Commerce Adoption in the Philippines 2024-05-02T13:30:46+00:00 Rona Jane Policarpio policarpiorona16@gmail.com Ederliza Magpantay ederlizam@icloud.com <p style="text-align: justify; margin: 0cm 0cm 12.0pt 0cm;"><span lang="EN-US" style="color: black; background: white;">The primary objective of this study was to investigate the influence of Filipino women's existing digital access and literacy levels on their adoption of e-commerce. The researcher utilized the Multivariate Linear Regression Model via Ordinary Least Squares (OLS) Regression in exploring and quantifying the relationship and influence of the regressors and regressand. The OLS estimates suggest that higher data privacy awareness correlates with increased e-commerce adoption of women for purchasing goods and services online. On the other hand, improved digital skills are linked to increasing women's e-commerce adoption in terms of selling goods and services online. The two regression models have different significant variables, implying that consumers and sellers prioritize different factors when deciding to adopt e-commerce.</span></p> 2024-05-14T00:00:00+00:00 Copyright (c) 2024 UJoST- Universal Journal of Science and Technology http://ujost.org/index.php/journal/article/view/152 Investigation of the Role of Digital Marketing, Competitive Advantage and Digital Business Strategy on Financial Performance 2024-04-23T10:24:37+00:00 Rayyan Aqila Praditya admin@ujost.org <p>This research was carried out to examine the influence of competitive advantage and digital business strategy on financial performance which is moderated by digital marketing in micro, small and medium enterprises.

This study aims to assess the factors behind food insecurity in the Philippines and their extent using regional data from the years 2015, 2018, and 2021. The panel quantile regression analysis was utilized to determine and assess the economic factors affecting food insecurity. The researcher was also able to gauge which regions have the least, moderate, and high prevalence of food insecurity using the 25th, 50th, and 75th quantiles of the dependent variable, respectively. Using the percentile scores in data distribution, the National Capital Region, Region III (Central Luzon), and Region IVA (CALABARZON) are regions with the least prevalence of food insecurity. The regions with a moderate prevalence of food insecurity are Region IVB (MIMAROPA), Region VI (Western Visayas), and Region XI (Davao). On the other hand, regions with a high prevalence of food insecurity are Region IX (Zamboanga Peninsula) and Bangsamoro Autonomous Region in Muslim Mindanao. Other regions were determined to have experienced different levels of prevalence of food insecurity in different years. The quantile regression results revealed that poverty incidence and economic growth have a significant positive relationship, and the minimum wage has a significant negative relationship with food insecurity across all levels of food insecurity prevalence by region. The consumer price index of food was found to be a statistically significant factor and is positively correlated with food insecurity only in regions where food insecurity is highly prevalent. It is also an insignificant factor in regions with the least and moderate prevalence of food insecurity.</p> 2024-05-14T00:00:00+00:00 Copyright (c) 2024 UJoST- Universal Journal of Science and Technology http://ujost.org/index.php/journal/article/view/153 Linking the Role of Promotion of Access to Digital Facilities, Social Media and Digital Literacy on Marketing Performance 2024-04-23T10:44:06+00:00 Rayyan Aqila Praditya admin@ujost.org <p>This research attempts to fill the gap in the differences in the relationship between promotion and marketing performance. Considering that currently social media has become so important, this research focuses on promotion via social media. Social media promotions have different influences on marketing performance, where these differences depend on the digital access that business actors have. Therefore, digital access is positioned as a moderator between social media promotion and marketing performance. Digital access is used as moderation because it can increase or decrease marketing performance. This research reviews the variables of social media promotion and digital literacy with access to digital facilities as a moderation of marketing performance. This research method is qualitative research, data comes from 456 respondents with data collection methods using questionnaires. The method for data analysis uses a structural model processed with smartPLS. 3.0. The result is that social media promotion has an effect on marketing performance, digital literacy has an effect on marketing performance, access to digital facilities is not able to moderate social media promotion and digital literacy has an effect on marketing performance.</p> 2024-04-23T00:00:00+00:00 Copyright (c) 2024 UJoST- Universal Journal of Science and Technology http://ujost.org/index.php/journal/article/view/150 Investigation of the Influence of Price, Promotion and Innovation on Customer Satisfaction in the Digital Era 2024-04-23T10:04:40+00:00 Rafie Zaidan Prayuda admin@ujost.org <p>The aim of this research is to analyze the influence of price, promotion and innovation on customer satisfaction.
