Abstract

Anodizing is a metal coating technique by converting a metal surface to form an oxide layer by electrolysis, one of which is to increase the hardness of a material. This research was carried out to know the effect of variations in electrolyte solution on the hardness of the coating resulting from the anodizing process. The electrolyte used is a solution of NaOH (Sodium Hydroxide) with a concentration of 1 M solution of 68% purity. The specimen used is magnesium AZ31, voltage 10 Volts, soaking time 10 minutes at room temperature. Based on the data analysis results, the magnesium layer's hardness value at 10 minutes at a voltage of 10 volts is 69 HV.In comparison, the coating thickness result at 10 minutes with a constant voltage of 10 volts is 6 ?m. While the concentration of the solution is 0.5 M, the purity is 68%. The specimen used is magnesium AZ31, voltage 10 Volts, soaking time 10 minutes at room temperature. Based on the results of data analysis, the hardness value of the magnesium layer at 10 minutes at a voltage of 10 volts is 67 HV. In comparison, the coating thickness at a time of 10 minutes with a constant voltage of 10 volts is 4 ?m. With variations in stress and time in different concentrations of the solution, there will be differences in the hardness value and thickness value of the AZ31 magnesium coating material.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilaksanakan dengan tujuan untuk meningkatkan pemahaman serta keterampilan dalam manajemen laboratorium, sekaligus menumbuhkan kesadaran akan pentingnya penerapan Keselamatan dan Kesehatan Kerja (K3) di lingkungan sekolah kejuruan. Program ini diselenggarakan di SMK Tri Sukses Natar, Lampung Selatan, yang memiliki fasilitas laboratorium teknik namun masih memerlukan penguatan dalam aspek pengelolaan dan implementasi prosedur K3. Metode kegiatan mencakup pelatihan, sosialisasi, serta pendampingan langsung bagi guru dan siswa dalam upaya menciptakan sistem pengelolaan laboratorium yang efektif, efisien, dan aman. Berdasarkan hasil pretest, tingkat pemahaman peserta terhadap manajemen laboratorium dan penerapan K3 masih tergolong rendah, dengan nilai rata-rata 60,42 dari 100, median 61, dan rentang nilai 12 hingga 81, diikuti oleh 12 dari 14 peserta pelatihan.Setelah pelatihan dilaksanakan, hasil posttest menunjukkan adanya peningkatan signifikan dalam pemahaman peserta mengenai manajemen laboratorium dan K3, dengan nilai rata-rata 80 dari 100, median 81, serta rentang nilai 20 hingga 100, diikuti oleh seluruh 14 peserta.Melalui kegiatan ini, diharapkan SMK Tri Sukses Natar mampu menerapkan sistem manajemen laboratorium yang lebih tertata, efisien, dan berorientasi pada keselamatan kerja sesuai dengan standar praktik di bidang pendidikan vokasi.

Abstract

In the context of vocational education, technicians play a crucial role as partners to teachers in laboratory or workshop settings in schools specializing in machining technology. Despite having received training at their institutions, many technicians lack sufficient competence to optimally support learning activities. This community service initiative aims to enhance the professional competence of technicians in vocational schools through a structured approach. The activity begins with a field study to assess specific needs, followed by the development of a training model that is then reviewed through a Focus Group Discussion (FGD). This training model is designed to provide technicians and laboratory teachers with comprehensive insights into best practices and effective self-development guidelines. The expected outcome is a significant improvement in the competencies of technicians and laboratory teachers in Bandar Lampung.

Abstract

Pengelasan merupakan salah satu teknologi penyambungan logam yang penting dalam aplikasinya di dunia industri manufaktur. Pengelasan maju merupakan teknik pengnyambungan logam tanpa proses pencairan logam induk atau sering dikenal dengan solid-state welding. Teknik pengelasan maju telah berkembang pesat seiring dengan kemajuan teknologi material dan proses manufaktur logam industri. Meski demikian, pemahaman tentang pengelasan maju di kalangan guru dan siswa sekolah menengah keujuruan (SMK) di Bandar Lampung masih terbatas dan belum terdiseminasikan dengan baik. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk meningkatkan kompetensi guru dan siswa SMK 2 Mei Bandar Lampung dalam bidang pengelasan maju. melaksanakan diseminasi hasil-hasil penelitian dosen dan untuk meningkatkan kompetensi guru dan siswa SMK 2 Mei Bandar Lampung melalui pelatihan pengelasan maju. Kegiatan PKM ini difokuskan pada teknologi pengelasan tanpa pencairan (solid-state welding) dengan teknik friction stir welding (FSW) dan friction welding (FW) yang dapat diaplikasikan dengan mesin frais dan mesin bubut di Lab produksi. Kegiatan ini secara keseluruhan, mampu meningkatan pemahaman peserta sebesar 51%. Pelatihan ini juga diharapkan dapat menjadi model untuk peningkatan kompetensi guru dan siswa di SMK melalui diseminasi hasil penelitian dosen Unila yang dapat diterapkan di masing-masing sekolah SMK di Bandar Lampung

Abstract

Abstrak Pleurotus ostreatus mushroom cultivation is a promising business opportunities in Bandar Lampung, as for one mushroom’s growing media (baglog) may produces for harvesting mushrooms every day up to 4-5 months. However, the success and quality of the mushroom production depends on the quality of mushroom’s growing media (baglog) preparation. Baglog preparation process is done through several steps, starting with preparing and mixing the raw materials to get a homogeneous and optimal dough, then subsequent compression and packaging of growing media in a plastic bag, before sterilizing and placing the oyster mushrooms stem at the top of baglog. In the small-scale mushroom industry, the process of mixing and compression of growing media used to be done manually or by human power. This process may give a low degree of homogeneity and uncompact baglog. The objection of this community service program is to implement an automatic mixer and compression tools for baglog production at oyster mushroom plantation center at Pesantren Darussalam, Banjar Negeri, Natar, South Lampung. Kata kunci: Pleurotus ostreatus mushroom, baglog, mixer machine, compression tool
