Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Boangmanalu, Kecamatan Salak, Kabupaten Pakpak Bharat, dengan tujuan untuk meningkatkan produktivitas dan daya saing usaha gambir mitra. Selama ini, mitra menghadapi kendala utama pada proses pengepresan getah gambir yang masih menggunakan alat sederhana sehingga kapasitas produksi rendah. Solusi yang ditawarkan adalah penyerahan mesin screw press gambir berkapasitas 100 kg getah gambir perjam, disertai dengan pelatihan dan pendampingan berkelanjutan. Metode pelaksanaan meliputi perencanaan, perakitan dan uji coba mesin, serah terima, serta pelatihan teknis dan manajerial. Aspek teknis yang diberikan antara lain penggunaan mesin screw press, teknik perebusan, pengendapan, dan pengeringan getah gambir sesuai standar mutu. Sementara itu, aspek manajerial meliputi pelatihan pengemasan produk, pemasaran melalui marketplace (Shopee), pendampingan dalam pengurusan izin berusaha, serta penyusunan analisis SWOT sebagai strategi pengembangan usaha. Hasil kegiatan menunjukkan bahwa mitra mampu mengoperasikan mesin screw press dengan baik, memahami prosedur produksi gambir yang berkualitas, serta memiliki keterampilan tambahan dalam pemasaran digital dan legalitas usaha. Melalui kegiatan ini, kapasitas produksi gambir meningkat signifikan, mutu produk menjadi lebih terstandar, dan mitra memiliki strategi usaha yang lebih jelas. Dengan demikian, pengabdian ini berkontribusi dalam meningkatkan produktivitas, daya saing, serta kesejahteraan mitra dan masyarakat sekitar.

Abstract

This study aims to evaluate the quality of tensile testing conducted at the Mechanical Engineering Laboratory of Politeknik Negeri Medan. Based on the results of attribute inspection, there were 42 units of material defects with a value of 0.124260355. The Upper Control Limit (UCL) was 0.415734865, and the Lower Control Limit (LCL) was 0.0167214 or 0. The subsequent check sheet showed that 34 test specimens did not meet the standard. The  value was 0.0100591716, the UCL was 0.03631557869, and the LCL was 0.00362 or 0. The next check sheet revealed 25 failed tests with a  value of 0.0073964497, a UCL of 0.0299413849, and an LCL of -0.0151484 or 0.
