<p>Penelitian ini dilakukan di UMKM X pada bagian <em>Quality Control</em> dan <em>Packing</em> dengan tujuan menganalisis postur kerja karyawan. Metode yang digunakan adalah <em>Nordic Body Map</em> (<em>NBM</em>) dan <em>Rapid Upper Limb Assessment</em> (RULA). Hasil analisis postur kerja menggunakan metode NBM menunjukkan bahwa pekerja 1 memiliki risiko cedera otot pada bagian pinggang, pekerja 2 pada kaki kanan dan kiri, serta pekerja 3 pada punggung, lengan atas kiri, pinggang, dan lengan atas kanan. Skor <em>NBM</em> menunjukkan bahwa tingkat risiko cedera pekerja 1 dalam kategori "Rendah" pada skala Likert 1 dengan total skor individu antara 28-49, yang berarti belum diperlukan tindakan perbaikan. Sementara itu, risiko cedera pekerja 2 dan 3 berada dalam kategori "Sedang" pada skala Likert 2 dengan total skor individu antara 50-70, yang mengindikasikan perlunya tindakan perbaikan di masa mendatang. Berdasarkan metode <em>RULA</em>, pekerja 1 dan pekerja 2 mendapatkan skor akhir 5, dan pekerja 3 mendapatkan skor akhir 6. Ketiga pekerja tersebut berada pada tingkat risiko 3 yang berarti "Sedang" dan memerlukan tindakan segera. Usulan perbaikan meliputi penyediaan meja dan kursi kerja yang dapat disesuaikan, serta memungkinkan ketiga pekerja untuk beristirahat sekitar 10 menit selama bekerja untuk meregangkan otot. Hasil penelitian sangat penting sebagai acuan perbaikan postur kerja.</p>Indri Ayu SansabilaHarmoko HarmokoRisal NgizudinRaditya Jarwenda Novasani

https://mand-ycmm.org/index.php/eatij/article/view/746
<p>Pada saat ini bahan bakar bukan yang dihasilkan dari bumi sudah sangat menipis dan emisi gas yang dihasilkan oleh bahan bakar sangat mempengarhui terjadinya peningkatan pemanasan global. Untuk itu diperlukan substitusi bahan bakar yang lebih ramah lingkungan dengan emisi gas sekecil mungkin. Natural gas adalah bahan bakar yang saat ini digunakan sebagai salah satu alternatif pengganti bahan bakar minyak. Pengelolaan gas alam memerlukan berbagai sistem tata Kelola antara lain pendistribusian gas menggunakan sistem <em>virtual gas paping </em>atau disebut dengan gas alam terkompresi. Gas tersebut didistribusikan menggunakan tangki bertekanan tinggi dari stasiun pengisian gas alam ke masing-masing pengguna atau pelanggan. Salah satu faktor yang memenuhi kriteria distribusi gas adalah tekanan gas yabg didistribusikan ke pengguna, tekanan gas tersebut harus mampu disimpan pada tekanan tinggi yang pada umumnya berkisar antara 200 bar sampai 250 bar. Untuk mencapai tekanan tersebut diperlukan gas kompresor yang mampu menekan gas hingga 250 bar yaitu <em>piston double acting.</em> Untuk mendapatkan mesin yang mampu melakukan kompresi sesuai dengan karakteristik yang diperlukan maka penyesuaikan dilakukan dalam perencanaan, pemilihan, <em>design, </em>instalasi, <em>commissioning </em>yang baik agar kapasitas yang diisyaratkan dapat terpenuhi dengan baik.</p>Cahyo WibowoHerbert Hasudungan SiahaanOjakma Sihar Panaili T
