Abstract

Rembangan Dairy Farm, which is located at UPT Livestock Breeding and HPT Rembangan WM8R+734, Darungan, Kemuning Lor, Kec. Arjasa, Jember Regency, East Java, is a cow's milk processing industrial area. The purpose of this study is to find out how the agro-industry forms in Rembangan Dairy Farm. The research method applied in this study is qualitative research with a case study approach. Data collection techniques through observation, interviews and documentation. Data analysis uses descriptive analysis according to the facts found in the field. The results of this research are that the milk processing process in industry still uses a simple method, namely the pasturization stage. The dairy products produced consist of two types, namely pure fresh milk without any additions and fresh milk with a variety of flavors. Milk marketing techniques are carried out online via social media Instagram and Whatsapp, and also offline through milk outlets and business partners. Marketing of fresh milk by business partners needs to be further improved in maintaining the durability of milk using refrigerators or freezers, this is because fresh milk is susceptible to temperature so it can easily spoil if not stored in the correct way. There is a need for further education for business partners to be able to maintain product quality by storing it properly so that the products being marketed do not suffer damage when in the hands of consumers.

Abstract

Improving students scientific communication skills in the learning process has become a recent challenge. Scientific communication is one of the essential skills required, particularly in science education. The purpose of this research was to develop a learning tool of project based learning-science, technology, engineering, and mathematics (PjBL-STEM) to improve scientific communication skills and learning outcomes of the grade XII students on the topic of engineering and technology. This research employed a research and development (RD) method through 4-D model approach (define, design, develop, and disseminate). The study involved students of SMAN 5 Jember to implement a small (N=30) and large-scale (N=60) for this research. The research instruments of this study were expert validation, teacher and student response questionnaires, learning outcome tests, and scientific communication skills test. Expert validation showed that the learning tools (teaching instructional design, student worksheets, learning materials, and assessments) were excellent, with an average score above 4.0. Practicality tests by teachers and students confirmed the usefulness of this tool, categorizing it as "very practical" to "practical". In addition, the device significantly improved students' scientific communication skills (significance values of 0.001 and 0.000) and learning outcomes (mean scores of 77.43 for the small group and 77.35 for the large group). This study concludes that the developed PjBL-STEM device is feasible, practical, and effective in supporting 21st-century learning
