Abstract

Laboratories that meet ergonomic standards will support the learning process, both academically and technically, to facilitate the growth and development of skills. This study aims to uncover and provide an overview and information about laboratory ergonomics standards which include thermal comfort (temperature), workspace laboratory lighting. This study uses a quantitative approach with a survey method carried out in the Machine Tool Unit Laboratory of the Department of Mechanical Engineering Education with a population of 60 students who are carrying out practicum. Techniques using direct observation and measurement. Lux Meter to measure lighting and then Digital Thermometer which functions to measure temperature at the observation point in the laboratory. Data collection starting at 07.00 until 12.00 and in the afternoon starting from 13.00 to 16.00, which is the time to do work activities. Measurements made at ten observation points the results showed that; (1) thermal comfort (temperature) with a value of 30.44 degrees Celsius, while the ideal practical standard ranges from 24 – 27 degrees Celsius; (2) Lighting with a value of 422.14 Lux while the ideal practice standard ranges from 500 – 1000 Lux. These results indicate that there is a tendency for temperature and lighting in laboratory rooms under conditions that are less than the standard set. To increase work productivity, these factors can cause less concentration and stress at work.

Untuk mengetahui apakah terdapat pengaruh yang signifikan antara lingkungan kerja terhadap kinerja karyawan di PT. Sermani Steel Corporation. Variabel dalam penelitian ini adalah Lingkungan Kerja (Y), Kinerja Karyawan (X). Adapun sampel ditentukan menggunakan teknik sampling jenuh sehingga diperoleh sampel sebanyak 48 orang, Teknik pengumpulan data yang digunakan adalah lembar kuesioner. teknik analisis data yang digunakan adalah uji instrumen, uji asumsi klasik, uji hipotesis dengan menggunakan aplikasi SPSS 30 For Window. Berdasarkan Metode yang digunakan adalah kuantitatif dengan analisis regresi linier sederhana. Hasil penelitian menunjukkan bahwa lingkungan kerja berpengaruh signifikan terhadap kinerja karyawan. Hal ini dibuktikan dengan nilai signifikansi sebesar 0,00 (< 0,05) dan nilai t hitung sebesar 6,837 yang lebih besar dari t tabel sebesar 1,679. Selain itu, nilai koefisien determinasi (R Square) sebesar 0,504, menunjukkan bahwa lingkungan kerja mampu menjelaskan 50,4% variasi dalam kinerja karyawan, sementara sisanya dijelaskan oleh variabel lain di luar model. Dengan demikian, bahwa semakin baik lingkungan kerja yang disediakan oleh perusahaan, maka semakin tinggi pula kinerja karyawan yang dihasilkan. Penelitian ini memberikan implikasi bahwa perusahaan perlu memperhatikan dan meningkatkan aspek-aspek dalam lingkungan kerja untuk mendorong kinerja yang optimal

Abstract

This community service program aims to implement a community-based biogas reactor as an alternative energy solution and sustainable livestock waste management system in Laikang Village, Mangarabombang District, Takalar Regency, South Sulawesi, Indonesia. The main problems faced by the partner community were the accumulation of cattle manure causing environmental pollution and the high dependence on subsidized liquefied petroleum gas (LPG). The program was carried out for eight months using a participatory and appropriate technology approach, involving the community at every stage, including planning, reactor construction, technical training, and performance evaluation. A 6 m³ anaerobic biogas reactor was successfully designed, built, and operated using cattle manure and water in a 1:1 ratio. Field measurements showed that the reactor produced 1.0–1.2 m³ of methane gas per day, replacing approximately 30–35% of household LPG consumption. The fermentation process also produced 10–15 liters of slurry per day, which was further utilized as liquid organic fertilizer. The program’s impact includes a 70% reduction in open livestock waste, 30% reduction in household energy costs, and the establishment of a Village Energy Self-Reliance Group (Kelompok Energi Mandiri Desa – KEMD) responsible for long-term management of the biogas system. The results demonstrate that community-based biogas technology effectively promotes rural energy independence, environmental awareness, and local economic empowerment. This initiative aligns with the Sustainable Development Goals (SDGs), particularly Goal 7 (Affordable and Clean Energy) and Goal 13 (Climate Action). The implemented model can serve as a replicable prototype for other coastal and rural communities in Indonesia with similar livestock and energy challenges.

Abstract

Perkembangan teknologi digital pada era industri 4.0 membuka peluang besar bagi pendidikan vokasi untuk meningkatkan kualitas pembelajaran praktik melalui solusi berbasis simulasi. SMK Negeri 1 Enrekang menghadapi tantangan keterbatasan fasilitas laboratorium teknik pemesinan yang hanya berjumlah dua unit untuk melayani lebih dari 1.200 siswa, sehingga menghambat pemenuhan jam praktik yang ideal. Selain itu, kompetensi guru dalam penggunaan teknologi pembelajaran modern masih terbatas, khususnya teknologi Virtual Reality (VR) dan Augmented Reality (AR). Padahal, kedua teknologi ini berpotensi memberikan pengalaman belajar yang imersif, aman, dan fleksibel bagi siswa. Melalui Program Kemitraan Masyarakat (PKM) yang didanai oleh PNBP Pengabdian Masyarakat Fakultas Teknik Universitas Negeri Makassar, dilakukan intervensi berbasis teknologi untuk meningkatkan kualitas pembelajaran praktikum. Kegiatan mencakup lima tahap, yaitu identifikasi kebutuhan, pelatihan guru, implementasi VR/AR dalam pembelajaran teknik pemesinan, pendampingan intensif, dan evaluasi akhir. Teknologi VR digunakan untuk simulasi pengoperasian peralatan pemesinan, sedangkan AR dimanfaatkan untuk visualisasi 3D komponen mesin menggunakan aplikasi Assemblr. Hasil kegiatan menunjukkan peningkatan signifikan pada kompetensi guru dalam mengoperasikan perangkat VR/AR serta kemampuan mereka menyusun modul pembelajaran digital berbasis simulasi. Siswa mengalami peningkatan pemahaman konsep, motivasi belajar, dan kepercayaan diri dalam melakukan praktik melalui pengalaman visual yang lebih realistis. Program ini juga berhasil mengatasi keterbatasan laboratorium dengan menghadirkan alternatif pembelajaran praktikum yang mudah diakses secara mandiri. Selain menghasilkan produk teknologi dan modul pembelajaran, program ini memiliki potensi kuat untuk direplikasi di sekolah vokasi lain. Temuan ini menegaskan bahwa integrasi VR/AR merupakan strategi efektif dan berkelanjutan untuk meningkatkan kualitas pembelajaran vokasi dalam menghadapi tuntutan industri digital.

Abstract

Purpose – This study aims to examine the role of industrial competencies in strengthening vocational curricula in the metaverse era, particularly in response to the demands of Industry 4.0 and 5.0. The study argues that vocational education must move beyond conventional curriculum design by integrating technical, digital, and adaptive competencies aligned with specific industrial job positions.Methods – A qualitative multi-method design combined a multi-case study and qualitative meta-synthesis. Primary data were collected from industry partners and Universitas Negeri Makassar through interviews, observations, and document analysis. Secondary data came from relevant 2020–2025 studies on industrial competencies, vocational curriculum, immersive learning, and industry–education collaboration.Findings – The results show that production operators, technicians, CNC operators, and QC/QA officers require distinct competencies, including occupational safety, measurement, technical drawing, machining, CNC programming, product inspection, and quality improvement. Digital literacy, teamwork, critical thinking, adaptability, and problem-solving are also essential. Research implications – The study implies that vocational curriculum development should integrate immersive technology, personalized learning, and stronger link-and-match collaboration with industry through joint projects and hybrid classes. However, implementation may be limited by infrastructure, resources, and regulatory readiness.Originality – This study contributes a synthesized perspective on aligning industrial competencies, metaverse-based learning, and vocational curriculum transformation to prepare digitally adaptive and technically skilled graduates for high-tech industries.
