Abstract

This research aims to evaluate the influence of Green Product Milo packaging on consumer buying interest. A quantitative descriptive research method was used by applying path analysis through a questionnaire distributed to 120 Milo consumer respondents. The research results show that Green Product adoption has a positive effect on repurchase intention. The implication is that companies need to maintain Green Products by continuing to innovate quality and environmentally friendly products and increasing promotions through potential media such as Instagram. Statistical analysis shows that there is a significant relationship between the level of product completeness and consumer attractiveness (p < 0.05). Although the correlation between the level of environmentally friendly products and purchase intention is relatively weak (correlation 0.411), the regression model shows a positive influence. From the results of ANOVA calculations, this regression can be used to predict purchasing interest in environmentally friendly products. It can be concluded that Green Products have a significant influence on consumer buying interest by contributing 16.9% to the variability in buying interest. This research provides an important contribution to companies in making strategic decisions related to product development and marketing.

Abstract

Stimulation of early childhood development varies widely, from expensive methods to utilizing recycled materials. The stimulation of early childhood development at TK Bustanul Athfal Ketegan Sidoarjo is still relatively limited. The goal of this activity is to enhance the cognitive and motor skills of young children and improve the educators' skills at TK Bustanul Athfal Ketegan Sidoarjo by creating stimulation play media using recycled materials as a tool for early childhood learning. The method for this activity includes presentations and training for educators on how to create cognitive and motor development stimulation media for children using recycled materials, as well as engaging in role-playing activities to utilize these stimulation media. The benefits of this activity include expanding the variety of learning media and enhancing the knowledge and skills of educators at TK Bustanul Athfal Ketegan Sidoarjo in creating learning stimulation media for their students using recycled materials. While a small portion of the teachers has not fully understood APE (Early Childhood Stimulation), 90% have comprehended the effective methods of creating and applying APE block number and APE Flashcard

Abstract

Salinity is among the factors that affect aquaculture water quality, along with pH, temperature, dissolved oxygen (DO), and ammonia. The osmotic pressure is influenced by salinity, which directly affects the aquatic biota. An osmotic pressure increases with increasing salinity in a body of water. The threshold salinity varies between aquatic biotas. If there is an isoosmotic pressure, the aquatic biota will thrive. Specific gravity, electrical conductivity (EC), light refraction, and chlorine titration are commonly used in salinity tests. Refractometer light refraction and water quality monitoring (WQM) salinity sensor EC were the salinity measurements employed in this research. In general, difficulties experienced while employing EC measurements to the tool's accuracy and precision. The salinity sensor was evaluated and verified in this research by comparing the findings of WQM readings with a refractometer over a three-day term. The sensors of 22 WQM devices were tested and validated in 22 BLUPPB (Balai Layanan Usaha Produksi Perikanan Budidaya, Aquaculture Production Business Service Center) ponds. The WQM was put in the center of the pond, and salinity was measured with a refractometer at four spots around the pond's edge. On the first trial, the WQM error and accuracy values were 19.90% and 80.10%, respectively; on the second trial, they were 9.58% and 90.42%, and on the third attempt, they were 16.21% and 83.79%. WQM accuracy was 0.7128, 0.7285, and 0.7174 on the first, second, and third time
