UMKM adalah usaha perdagangan yang dikelola oleh badan usaha atau perorangan yang merujuk pada usaha ekonomi produktif. UMKM harus menghasilkan produk yang kompetitif, berkualitas, dan memiliki daya saing tinggi, karena di era globalisasi ini, konsumen sangat kritis dan menuntut standar mutu produk yang melindungi kesehatan dan lingkungan, selain itu konsumen juga menuntut dalam aspek agama dan sosial budaya. Salah satu aspek yang dituntut oleh konsumen adalah kehalalan produk. Produk halal bukan lagi menjadi paradigma yang dikaitkan dengan agama khususnya islam, akan tetapi sudah menjadi bagian dari persaingan bisnis dan perdagangan. Halal adalah segala sesuatu yang diizinkan dalam agama Islam untuk digunakan atau dilakukan, istilah ini lebih sering digunakan untuk menunjukkan makanan dan minuman yang diizinkan untuk dikonsumsi menurut Islam. Makanan dan minuman tidak hanya harus halal, tetapi juga harus thayyib yang berarti "baik", termasuk apakah mereka layak dikonsumsi atau tidak, dan apakah mereka bermanfaat bagi kesehatan baik kesehatan jasmani, kesehatan rohani maupun kesehatan lingkungan. Sebagai wilayah dengan mayoritas penduduk muslim Kecamatan Mranggen diharapkan menerapkan hukum terutama ketentuan dalam hal produk yang halal, sehingga masyarakat merasa aman dan nyaman untuk mengkonsumsi produk yang beredar di masyarakat. Saat ini, masih banyak pelaku UMKM yang mengklaim halal produknya secara personal dibandingkan melalui audit dari badan atau institusi yang berwenang dalam penyelenggaraan jaminan produk halal. Berangkat dari permasalahan tersebut, peneliti ingin berperan aktif dengan melakukan pelatihan dan pendampingan halal pelaku UMKM melalui kegiatan Peningkatan Enviromental Add Value Usaha Mikro Kecil Dan Menengah (UMKM) Melalui Pelatihan Sertifikasi Halal Di Kecamatan Mranggen.

The integration of interdisciplinary approaches in science education has gained increasing prominence, particularly within vocational school contexts. The research aims to identify the challenges faced by these teachers and to explore potential solutions for improving project-based instruction within the framework of Indonesia’s Merdeka Curriculum. This study investigates the perspectives of chemistry education graduates who are currently implementing interdisciplinary science projects in vocational schools across Central Java, East Java, and the Special Region of Yogyakarta. Employing a qualitative descriptive design, data were gathered from 25 purposively selected participants using an online open-ended questionnaire. Thematic analysis revealed several core challenges: limited pedagogical competence in project-based learning, difficulties in synthesizing natural and social science content, insufficient laboratory infrastructure and teaching materials, and restrictive curriculum policies that constrain instructional flexibility. These issues were especially pronounced among teachers with mono-disciplinary backgrounds in chemistry, who are now required to deliver integrated and contextualized learning. In response, the participants proposed actionable strategies, including training in contextual and project-based methodologies, mastery of interdisciplinary content, enhanced professional collaboration through musyawarah guru mata pelajaran (MGMP) / subject teacher forums, improved access to instructional resources, and flexible curriculum design. The study highlights the need for comprehensive and systemic support to enhance teachers’ capacity to deliver meaningful and vocationally relevant interdisciplinary science education. The findings provide critical insights for policymakers, curriculum developers, and teacher education institutions aiming to advance the implementation of holistic STEM education in vocational settings.

Indonesian education has undergone a curriculum change in the form of the "Merdeka Curriculum," where one of the challenges faced is the limited availability of teaching materials, which affects the learning process of students. Another challenge Indonesia faces is the low level of scientific literacy among students. Therefore, it is necessary to develop teaching materials in the form of an e-module based on socio-scientific issues to improve students' scientific literacy. The purpose of this study is to determine the feasibility, student responses, and effectiveness of the e-module, as well as to analyze the improvement in students' scientific literacy. This type of research is Research and Development (R&D) using the 4D development model, namely define, design, develop, and disseminate, to produce a product that is suitable for use. The developed e-module was validated by five experts and achieved a high validity level (90.3% for content and 90% for media). Student responses to the e-module showed very good results, with an average score of 60.85 for class X-3 and 61.59 for class X-4. The N-gain test showed significant effectiveness, with a score of 0.735 (high category) for class X-3 and 0.677 (medium category) for class X-4. The results of this study indicate that the socio-scientific issue-based e-module is effective in improving students' scientific literacy on the topic of global warming.
