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

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

Glass-ceramics are fine-grained polycrystalline materials produced by controlled crystallization in the glass phase. The raw material for glass ceramics is basalt rock from East Lampung mixed with additives (SiO₂, MgO, and CaO). The production of glass ceramics begins with melting at 1200 °C for 2 hours until melting. The melted basalt is quenched using aquadest water with a pH of 7 to produce glass material. The glass material is ground using a ceramic ball mill and sieved with a 325 mesh. The glass material undergoes nucleation at 600 °C for 2 hours, followed by crystallization at 1,050 °C for 3 hours, and thermal crystallization (devitrification) at 1,050 °C for 3 hours to form the crystalline phase. The additive composition was varied using the Taguchi method to analyze its effect on density. The density test results showed values ranging from 2.1 to 3.8 g/cm³, depending on the additive ratio used. An increase in CaO and MgO content tends to increase density due to the formation of crystalline phases such as pyroxene, anorthite, and olivine. Conversely, excessive addition of SiO₂ can reduce density due to the growth of amorphous phases. Taguchi analysis identified Silica (SiO2) as the Rank 1 parameter influencing density. Meanwhile, ANOVA analysis yielded an optimal percentage contribution of silica at 34.57%.

Abstract

Material joining techniques are divided into two categories: similar joints and dissimilar joints. The difference in thermal cycles experienced by each material is the reason why dissimilar welding is more challenging than similar welding. The welding process that joins two materials with different properties is commonly used to improve effectiveness and efficiency in production, as well as to improve product quality. This trend has become popular in the manufacturing industry, including in the manufacture of tailor welded blanks, transportation vehicle frames such as aircraft, trains, and cars, as well as in the manufacture of public and private vehicle accessories such as aircraft panels and exhausts. The materials currently widely used in exploration are stainless steel combined with carbon steel, as well as a mixture of stainless steel and low carbon steel, which is quite challenging to weld but offers the advantages of higher strength, corrosion resistance, and lighter weight. This challenge can be overcome through liquid welding methods, one of which is the "SMAW (Shielded Metal Arc Welding)" technique. This study used variations in welding time at 5, 10, and 10 m/minute. Quality testing was carried out using visual tests, tensile tests, and impact tests, using AISI 1020 steel and AISI 1050 steel. Based on the test results, there was a significant difference in that the welds appeared to be shinier. The tensile strength results were in the form of average strain values for each specimen, which were 0.0705 mm, 0.0487 mm, and 0.1074 mm. The impact test results, which compared toughness values using a predetermined welding time variation of 16.5 joules, showed an average toughness value of 0.1948 J/mm².

Abstract

Cortical bone drilling represents an initial stage in orthopedic surgical procedures prior to implant screw insertion, where the quality of the drilled hole is strongly influenced by burr formation along the hole edges. Excessive burrs may increase the risk of tissue trauma, interfere with screw placement, and elevate the likelihood of postoperative complications. This study aims to investigate the effects of drilling parameters on burr characteristics during cortical bone machining and to determine the optimal parameter conditions that minimize burr formation. The research was conducted experimentally using fresh bovine cortical bone specimens and employed a Response Surface Methodology (RSM) experimental design. The investigated parameters included spindle speeds of 500, 1000, and 1500 rpm, feed rates of 35, 60, and 85 mm/min, and cooling conditions consisting of NaCl solution, Opsite Spray, and dry drilling. Drilling experiments were performed using a three-axis CNC machine, while burr characteristics were visually evaluated using a USB microscope. The results indicate that feed rate is the most influential parameter affecting burr formation, followed by spindle speed and cooling condition. Drilling conditions characterized by low feed rates, high spindle speeds, and the application of cooling fluids either NaCl solution or Opsite Spray produced smaller burrs and smoother hole-edge morphologies. The optimal condition was achieved through a specific combination of parameters that minimized burr formation, thereby demonstrating potential improvements in hole quality and procedural safety during cortical bone drilling.
