Pendidikan di Indonesia merupakan hak bagi semua anak bangsa, baik yang ada di tanah Indonesia maupun yang sedang berjuang di negara lain. Para pejuang devisa selain bekerja mencari uang mereka juga secara tidak langsung belajar skill dan pengetahuan baru. Hal ini dapat dimanfaatkan untuk mengikuti program rekognisi pembelajaran lampau (RPL). RPL adalah program pemerintah dengan tujuan memberikan kesempatan kepada seluruh penduduknya mendapatkan pengakuan formal yang berkaitan dengan keahliannya. Universitas Negeri Yogyakarta (UNY) merupakan salah satu perguruan tinggi yang dipercaya menyelenggarakan program tersebut. Untuk menyebarluaskan informasi mengenai program RPL kepada diaspora Indonesia, perlu dilakukan program sosialisasi program RPL tersebut terutama pada diaspora Indonesia di Préfecture Yamaguhi. Kegiatan ini bekerjasama dengan PPI Yamaguchi dan dilaksanakan secara hybrid (offline dan online). Terdapat 79 peserta yang hadir secara hybrid, namun hanya 22 peserta yang mengisi angket kepuasan. Secara umum peserta puas dengan kegiatan ini dan tertarik untuk dapat mengikuti program RPL. Sebagian kecil merasa bingung dan masih akan berfikir untuk mengikuti program ini. Kegiatan seperti ini perlu dilaksanakan tidak hanya di Jepang namun di beberapa negara lainnya untuk menngkatkan jumlah mahasiswa RPL di UNY.

Metal gaskets is an alternative to asbestor gaskets, but it still have many weaknesses. The main focus of this research is to find the optimal electroplating time to prevent leakage.This research was started with forming the gasket material, and then followed by coating process. The methode that used in coating proses was electroplating with nickel solution. The gasket material used SUS 304 sheet with 1,5mm of thickness. Water pressure test was used to test leackage with 2 MPa, 4 MPa, 6 MPa, and 8 MPa presurre for 5 minute test duration. The result this research are (1) electroplating are effected by time, the longer time applied more nickel attached to the gasket, (2) the best performance on nickel electroplated gasket was on 32 minute and 45 second plating time, (3) electroplated nickel gasket performance was better than the original to prevent leakage from 2 to 8 MPa water pressure.

Sifat ramah lingkungan dari serat rami menyebakan penggunaannya sebagai penguat dalam matriks polimer terus berkembang. Namun, sifat hidrofilik yang dimiliki serat rami secara signifikan dapat menyebabkan ikatan antarmuka yang kurang baik ketika serat dijadikan penguat pada komposit polimer. Perlakuan kimia merupakan salah satu metode yang digunakan untuk mengurangi sifat hidrofilik serat rami. Penelitian ini bertujuan untuk mengetahui pengaruh variasi konsentrasi asam maleat terhadap sifat fisis serat rami seperti moisture content, densitas, dan diameter. Serat rami diperlakukan dengan berbagai konsentrasi asam maleat (2, 4, 6, 8, dan 10 wt.%). Hasil penelitian menunjukkan bahwa perlakuan kimia secara efektif mengurangi moisture content pada serat rami, dengan nilai terendah yaitu 8,52%, yang diamati pada sampel yang direndam dengan 6 wt.% larutan asam maleat. Demikian pula pada hasil pengukuran densitas, dimana densitas naik seiring dengan peningkatan konsentrasi asam maleat dan maksimal pada sampel konsentrasi 6 wt.% dengan nilai 1,4267 gr/cm3. Hal ini disebabkan terlarutnya sebagian daerah amorf pada permukaan serat, sehingga terjadi peningkatan compactness serat. Hal ini didukung oleh hasil pengukuran diameter dimana nilainya menurun secara konsisten dengan peningkatan konsentrasi. Modifikasi permukaan ini menunjukkan bahwa konsentrasi asam maleat 6 wt.% memberikan kondisi perlakuan yang optimal, yang diharapkan dapat meningkatkan ikatan antarmuka serat-matriks pada komposit polimer.

Materi pengecoran logam pada program keahlian Teknik Pemesinan di SMK Bika 1 masih diberikan sebatas teori. Hal ini belum sesuai dengan Keputusan Kepala Badan Standar, Kurikulum, dan Asesmen Pendidikan Kemendikud Ristek nomor 024/H/KR/2022 yang menyatakan bahwa pengecoran logam merupakan salah satu konsentrasi keahlian pada program keahlian pemesinan di SMK/MAK. Kesenjangan ini dijembatani oleh Tim pengabdi DPTM FT UNY dengan membuat sarana praktik pengecoran untuk SMK Bika 1. Metode Asset Based Community Development (ABCD) diterapkan dengan tahapan pembuatan sarana praktik pengecoran, pembuatan model pola, pelatihan dan pendampingan guru dan tendik, implementasi sarana praktik pengecoran pada siswa, dan evaluasi hasil kegiatan. Sarana untuk praktik pengecoran yang dibuat terdiri atas tungku krusibel, perangkat pembuat cetakan pasir, perangkat penuangan, model pola, dan modul pembelajaran. Sarana untuk praktik pengecoran dapat meningkatkan kompetensi guru dan tendik SMK Bika 1, yaitu telah memahami dan mampu melakukan proses pengecoran logam yang meliputi mengoperasikan tungku krusibel, membuat cetakan pasir, menuang logam cair dan membersihkan produk hasil pengecoran. Sarana untuk praktik pengecoran telah memenuhi kebutuhan SMK Bika 1 sebagai fasilitas penunjuang praktik. The metal casting subject is only given in theory at SMK Bika 1. This does not meet with the Decree of the Head of the Education Standards, Curriculum, and Assessment Agency of Kemendikbud Ristek Number 024/H/KR/2022 which states that casting is one of expertise in the machining program at SMK/MAK. This gap was bridged by the DPTM FT UNY team through making casting practice facilities for SMK Bika 1. The Asset Based Community Development (ABCD) method is applied through the stages such as making of casting practice facilities, pattern models development, training and mentoring for teachers and technicians, implementation of casting facilities on students, and program evaluation. The casting facilities consist of a crucible furnace, sand mold making equipment, pouring equipment, pattern model, and learning module. The facilities for casting practice can improve the teachers and education staff competence of SMK Bika 1, that are understand and capable of doing the casting process which includes operating the crucible furnace, making sand molds, pouring molten metal and cleaning the casting products. The casting facilities have met the needs of SMK Bika 1 as supporting facilities for practice.

Carbon fiber-reinforced epoxy (CFRE) has better performance properties and is commonly used in the aviation industry. The placement of carbon fiber will affect the mechanical properties of the resulting composite material. The specific application to actual components has yet to be discovered regarding the mechanical capabilities of the CFRE utilization. Therefore, it is essential to investigate further the mechanical behavior of CFRE composites with varying oriented carbon fibers, especially those produced using the vacuum infusion method with a volume fraction of 40%. This study presents an experimental investigation of the CFRE composite with varying oriented carbon fibers in unidirectional, bidirectional, and forged. The result shows composite materials' mechanical characteristics, particularly in the properties of Young's modulus, Poisson ratio, and shear modulus. The unidirectional fiber composites are only suitable for tensile loads in line with the fiber, while bidirectional fiber composites should be cautiously undertaken, as tensile loads applied to the Z-axis may lead to adverse effects; conversely, shear forces can be safely applied to all three axes. The forged fiber direction results in each loading direction having separate capabilities, which are challenging to anticipate. The application of CFRE on an actual component should entail the integration of diverse fiber orientations within a single composite layer, particularly in highlighting manufacturing folding arm components and their adaptability. The test results demonstrate that the maximum load that can be tolerated by the folding arm before failure fulfills the requisite strength criteria, thus allowing for a safety factor of 7.8, which confirms the safety of the CFRE with combined fiber orientation in producing folding arm components.
