Abstract

The increasing number of minimarkets in Ungasan Village causing the income of grocery store owners decreases, that makes grocery stall owners should implement a marketing mix strategy to be compete, by studying the behavior of minimarket consumers. This study aims to analyze the marketing mix factors that determine consumer decisions in choosing a minimarket to shop in Ungasan Village and find out the dominant factors so the results is expected to help grocery store owners in Ungasan Village. The stages of this study including preliminary survey, attribute identification based on marketing mix factors, questionnaire generating, reliability and validity testing, broadcasting the questionnaire to the consumers of grocery store, data gathering, data analyzing, and generating the results and the discussions. The study implemented by surveying 154 respondents, then from the results a factor analysis carried out using Microsoft Excel 2016 and SPSS 26. The results show that there are five factors betwixt accessibility factor, employee performance factor, promotion factor, physical evidence factor, and price factor. The accessibility factor is the dominant factor that determines consumer decisions in choosing a minimarket for shopping, with the attribute that has the highest correlation value is that the distance of the mini market is close to the dwelling (X8).

Abstract

Using petroleum-based plastics presents significant environmental challenges due to their difficulty in decomposition. This study explores the characteristics of bioplastic composites created from taro starch (Colocasia esculenta) and carrageenan, incorporating polycaprolactone (PCL) as a reinforcing agent. An experimental approach was employed, varying the ratio of taro starch to carrageenan (25:75 and 50:50) and the concentration of PCL (7.5%, 10%, 12.5%, and 15%). The evaluation included tests for tensile strength, elongation at break, elasticity, thickness swelling, and biodegradation. The results showed that the variation of the ratio of taro starch: carrageenan affected tensile strength, elasticity, and biodegradation but not elongation at break and swelling. In comparison, PCL reinforcement affected elongation at break and swelling but not tensile strength, elasticity, and biodegradation. Bioplastic composite with a ratio of taro starch: carrageenan of 25:75 and a concentration of PCL reinforcement of 12.5% ​​(0.75 g) with a tensile strength value of 10.37 ± 2.57 MPa; elongation at break of 2.11 ± 10%; elasticity of 520.07 ± 123.47 MPa; swelling of 70.18 ± 4.96% and the duration of biodegradation on the 5th day. FTIR analysis confirmed the presence of C-H, C-O, C=O, and O-H functional groups, indicating compatibility among the materials in forming the bioplastic composites. The results of this study suggest that bioplastics derived from taro starch and carrageenan, supplemented with PCL, could serve as a promising alternative for environmentally friendly packaging that biodegrades more effectively than traditional plastics.

Abstract

The high demand for healthier food is contributing to the innovation in pasta formulations, traditionally based on durum wheat semolina. In this context, recent reformulation has focused on the addition of plant-based and protein-rich ingredients, such as legumes, pseudocereals, fish protein, and dietary fiber, to enhance nutritional value and functional properties of pasta product. The reformulations cause an increase in protein, fiber content, amino acid, antioxidant capacity, glycemic control, and prebiotic activity. However, ingredient substitutions pose technological challenges, including changes in texture and high losses during the cooking process. Therefore, this study aims to optimize functional pasta product and address technological challenges by applying different processing methods such as fermentation, extrusion, and enzymatic treatments. The results showed that pasta fortification provided substantial nutritional benefits, although the impact on sensory characteristics posed a significant concern. This was because physicochemical properties of functional ingredients could alter the texture, color, and flavor of product, directly impacting consumer acceptance.

Abstract

Biocomposite foam offers an environmentally friendly solution to replace synthetic polymer-based packaging that is difficult to degrade. This study aimed to investigate the effect of taro leaf powder (Colocasia esculenta (L.) Schott) concentration on the characteristics of tapioca-and chitosan-based biocomposite foam, as well as to determine the optimal concentration for producing the best-performing foam. The research employed a Randomized Block Design (RBD) with five levels of taro leaf powder concentration: 1%, 1.5%, 2%, 2.5% and 3%, tested across four blocks based on biocomposite foam production time. The observed variables included tensile strength, tear strength, density, elongation at break, compression set, thickness, swelling, and biodegradation. Data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test. The results showed that variations in taro leaf powder concentration produced the best foam properties, with a tensile strength of 2.04 N/cm2, tear strength of 1.46 N/cm2, density of 0.22 g/mL, elongation at break of 2.77%, compression set of 17.28%, thickness of 12.78 mm, swelling of 0.84%, and a biodegradation time of 15.75 days.
