Abstract

The batik industry is a creative sector that contributes significantly to Indonesia’s economy through job creation and cultural preservation. Home Industry Batik Nurari, established in 2000 in Sidoarjo, produces various batik products, including hand-drawn batik fabrics, batik dresses, and uniforms. In response to digital transformation, Batik Nurari has utilized online marketplaces such as Shopee and Tokopedia since 2018. However, its online sales performance remains relatively low compared to similar competitors, mainly due to limited account activity, underutilization of marketplace features, and the absence of a structured digital marketing strategy. This study aims to design a systematic digital marketing strategy for a batik home industry with passive marketplace performance using the SOSTAC framework supported by quantitative SWOT analysis. The scientific contribution of this research lies in the contextual application of the SOSTAC model to a small-scale batik home industry with limited digital resources, a context that has received limited attention in previous studies. The results indicate that internal factors (strengths and weaknesses) achieve a total score of 3.30, while external factors (opportunities and threats) obtain a higher score of 3.80, demonstrating the dominant influence of external conditions on business performance. These findings suggest that digital marketing strategies should prioritize leveraging external market opportunities to enhance competitiveness and business sustainability.

Abstract

Metal casting is one of the manufacturing methods widely used to produce components with complex shapes and high precision. This study aims to evaluate the use of alternative molds based on a mixture of silica sand and bentonite in aluminum casting. Variations in the composition of silica sand and bentonite are applied in the casting process to observe their effects on the surface quality of the casting results and the efficiency of the production process. The results of field observations show that the optimal composition consists of 85% silica sand, 10% bentonite, and 5% graphite, which produces a mold mixture with good consistency, is not easily cracked, and is able to replicate pattern details with high precision. In addition, molds with this composition are easier to shape and have good resistance during the casting process, thereby reducing the risk of mold failure. Thus, molds based on silica sand and bentonite have the potential to be a more efficient and environmentally friendly alternative in metal casting technology.

Abstract

The utilization of log residue waste as an alternative raw material in the wood processing industry has the potential to improve resource efficiency; however, material heterogeneity often leads to product quality issues. This study aims to identify the dominant types of defects and their contributing factors in wooden cable pallets made from log residue waste, as well as to determine quality improvement priorities through the integration of Seven Tools of Quality and Quality Function Deployment (QFD). The study was conducted at UD Nurari Perdana Kabelindo, Sidoarjo, using production and defect data collected during September 2025 through observations, interviews, documentation, and questionnaires. The Seven Tools analysis employed check sheets, Pareto charts, and cause-and-effect diagrams to identify dominant defects and their root causes. The results were subsequently integrated into QFD through the development of a House of Quality to translate customer needs into priority technical characteristics. Customer requirements were determined based on product quality attributes obtained from 30 customer respondents using a census method. The results showed a defect rate of 11.51% of total production, with the dominant defects consisting of thickness deviation, wavy surfaces, knot defects, and asymmetrical circular shapes. The QFD analysis revealed that operator precision and raw material selection were the top priorities for quality improvement. These findings demonstrate that the integration of Seven Tools and QFD is effective in linking process defect analysis with customer needs to support sustainable product quality control.

Abstract

This study aims to analyze parents' responses to the trial implementation of the Free Nutritious Meal Program (MBG) conducted in several elementary schools in Trenggalek Regency. The MBG program, initiated by the government, is in its pilot stage and primarily targets improvements in students' nutritional intake, health, academic performance, and efforts to reduce stunting. mploying a mixed-methods approach, the research combined qualitative insights from in-depth interviews with parents, teachers, and school principals, alongside quantitative data gathered from structured questionnaires distributed to parents involved in the pilot program. The study evaluated variables such as food quality, hygiene, serving frequency, school–parent communication, and parental expectations and concerns regarding the program’s continuity. The findings reveal a largely positive response; parents particularly appreciated the program's role in fostering healthier eating habits and alleviating household financial burdens. However, several critical issues emerged, including limited menu variety, inconsistent food taste quality, and lack of transparency regarding meal schedules and nutritional content. Some parents expressed hope for the program’s expansion, provided that food quality and safety standards are maintained. Further analysis indicates that effective communication and parental involvement significantly influence satisfaction and support levels for the program. These insights offer valuable input for local governments and schools in refining MBG implementation to maximize its impact. This research contributes to a better understanding of the dynamics of the MBG pilot at the elementary school level and provides data-driven recommendations to enhance future policy and execution of free nutritious meal programs.

Abstract

The necessity of adequate housing constitutes a fundamental human need. CV Senjaya Makmur, a housing developer in Sidoarjo, faces the challenge of meeting the housing preferences of the millennial generation. The objective of this study is to ascertain the technical attributes required by millennial consumers to inform the design of residential houses. To this end, the Quality Function Deployment (QFD) method will be employed as a framework. The results of the study indicated that the factors considered by millennials include facade color, simple and trendy home design, construction cost, breathing house concept, distance to public facilities, long-term use, efficiency, and flexibility. The highest priorities are the cost of home maintenance (8.513%), the application of easy-care materials (8.494%), and cheap good quality finishing materials (8.329%). Other salient characteristics include optimal furniture arrangement (5.737%), integration of multifunctional spaces (5.508%), and the notion of multi-storey micro-houses (5.453%). These findings offer insights that can inform the design of residential properties to align with the needs and preferences of the millennial generation.Kebutuhan tempat tinggal layak merupakan kebutuhan primer manusia.

Abstract

This study aims to resolve operational issues of slow service and high order error rates at Cafe Pastor Ngagel Surabaya. Through a survey of 102 respondents, service quality was evaluated using the SERVQUAL method across 25 attributes. The results showed 13 attributes with positive gaps (such as friendly staff) and 2 with zero gaps, indicating customer satisfaction that must be maintained. Conversely, 10 attributes had negative gaps, with the worst being the lack of modern equipment (-0.559), interior design (-0.451), and coffee taste inconsistency (-0.324). These negative attributes were integrated into the House of Quality (HoQ) matrix using Quality Function Deployment (QFD). QFD established three top improvement priorities: (1) standardization of coffee preparation time (score 271.86), (2) taste calibration (212.62), and (3) equipment modernization (198.23). The practical implication is that management can precisely focus resources to improve service time efficiency and product consistency.
