This research is motivated by the implementation of conventional learning. Besides, student learning motivation is still low due to student activities that are less centered on making workpieces that are suitable for work in the industry. Learning outcomes show that only 55.88% of students reach Minimum Completeness Criteria (Kriteria Ketuntasan minimum or KKM). The design and learning of productive machining competencies that are in accordance with the needs of the industry influence students' experience and learning outcomes. This study aims to analyze the results of industrial project-based learning (InPro-BL) milling machine competency learning outcomes in SMK Negeri 1 Semarang. The method used in this study is Class Action Research (CAR) through four stages: (1) planning, (2) implementation of actions, (3) observation and evaluation, (4) reflection. The samples were 34 students of class XII of Mechanical Engineering. The data were collected using product assessment instruments to measure dimensional accuracy, timeliness, level of disability, level of smoothness, and work attitude. This study was descriptive quantitative, and qualitative. The results of the study show that InPro-BL is effective in improving the learning outcomes of milling machine competencies. In Cycle I, there is an increase in learning outcomes, from 19 students who completed the KKM to 25 students or 73.52%. In Cycle II, there are 88.23% of students passed the KKM. These results can be improved by paying attention to the management of learning time through the block system, teacher's understanding of industrial-project-based learning, and industry guest teachers mentoring every learning process.

AbstrakGula aren merupakan suatu bentuk produk olahan sari nira yang tercipta dari hasil tanaman aren. Gula aren mengandung banyak nutrisi diantaranya seperti kalium, zat besi, serat, magnesium, antioksidan, fosfor dan sebagainya. Gula aren juga sangat aman dikonsumsi untuk penderita diabetes, karena kadar inulin memiliki indeks glikemik yang rendah sebesar 35. Salah satu kelompok masyarakat pengolahan gula aren di Provinsi Jawa Tengah adalah Kelompok Usaha Bersama (KUB) UMKM Sukses Bersama “Sukma” yang beralamatkan di Desa Peron, Kecamatan Limbangan, Kabupaten Kendal. Kendala yang masih dihadapi sekarang ini adalah terbatasnya alat-alat produksi pengolahan pasca panen, sehingga jual beli gula aren belum sampai pada produk olahan pangan. Tidak hanya keterbatasan secara sarana alat produksi fisik, melainkan kemampuan pengetahuan dan keterampilan mitra sasaran juga masih terbatas untuk meningkatkan nilai tambah dan nilai ekonomis produk gula aren. Metode pelaksanaan adalah sosialisasi, pelatihan, penerapan teknologi, pendampingan dan evaluasi serta keberlanjutan program. Beberapa Teknologi Tepat Guna (TTG) yang diserahkan pada mitra sasaran diantaranya meliputi mesin pengaduk, kompor, tungku penggorengan, oven dan sebagainya. Sementara olahan pasca panen gula aren adalah mengolahnya menjadi brownies alpukat, brownies crispy alpukat, sus ula alpukat dan wedang kaduga. Sementara itu, pendampingan pemasaran digital usaha dilakukan dengan turut serta melibatkan peran aktif para mahasiswa. Kata kunci: diversifikasi produk; gula aren; pasca panen; pemberdayaan masyarakat; teknologi tepat guna. AbstractPalm sugar is a processed product made from the sap of the sugar palm plant. Palm sugar contains many nutrients, including potassium, iron, fiber, magnesium, antioxidants, phosphorus, and so on. Palm sugar is also very safe for consumption by diabetics, because the inulin content has a low glycemic index of 35. One of the palm sugar processing community groups in Central Java Province is the Joint Business Group (KUB) of the UMKM Sukses Bersama "Sukma" located in Peron Village, Limbangan District, Kendal Regency. The current obstacle is the limited production tools for post-harvest processing, so that the sale of palm sugar has not yet reached processed food products. Not only are there limitations in physical production facilities, but the knowledge and skills of target partners are also still limited to increase the added value and economic value of palm sugar products. The implementation method is socialization, training, technology application, mentoring and evaluation as well as program sustainability. Some Appropriate Technologies (TTG) handed over to target partners include stirring machines, stoves, frying pans, ovens and so on. Meanwhile, post-harvest palm sugar processing includes avocado brownies, crispy avocado brownies, avocado milk and kaduga drink. Digital marketing assistance for the business is provided with the active involvement of students. Keywords: product diversification; palm sugar; post-harvest; community empowerment; appropriate technology.

Medium-density fiberboard (MDF) is commonly used in furniture manufacture because of its consistent qualities, low cost, and ease of processing. However, its relatively short lifespan and rising market demand have resulted in substantial waste generation, posing serious environmental and disposal concerns. This study provides an integrated sustainable manufacturing and waste management framework for MDF that incorporates artificial intelligence technology and finite element method (FEM)-based structural optimization for bookshelf applications. The structural performance is evaluated by numerical simulations focusing on von mises stress, displacement, and safety factor. These findings indicate that combining FEM-based design optimization with intelligent waste management strategies might enhance the structural performance and sustainability of MDF products. This study emphasizes the necessity of merging advanced simulation, artificial intelligence, and life-cycle assessment methodologies to create intelligent, efficient, and ecologically responsible wood-based manufacturing systems.
