Abstract

FDM (Fused Deposition Modeling) 3D Printer tool training to support Teaching Factory (TEFA) in SMK aims to improve technical skills and students' readiness to face the challenges of industry 4.0. 3D printing technology has become an important innovation in the manufacturing world, which allows the creation of three-dimensional objects quickly and precisely. Therefore, mastery of this technology is very important for SMK, especially those involved in the TEFA program. This community service activity was carried out to provide practical training to teachers on how to operate an FDM 3D Printer, as well as understand the design and production process using three-dimensional printing technology. The training includes basic theory on how the FDM 3D Printer machine works, CAD programming, and steps in making prototypes and products using 3D printing. Through this training, it is hoped that Dian Kirana Sragen Vocational School can further strengthen the TEFA concept by providing facilities and tools that comply with industry standards. It is hoped that SMK Dian Kirana Sragen teachers can be better prepared to face the increasingly developing industrial world. The training was held through a combination of theory and direct practice methods, with the aim of providing a comprehensive understanding to participants. The results of this activity provide a real contribution to improving the quality of vocational education and strengthening the relationship between the world of education and the world of industry through TEFA products.

Abstract

Pembelajaran berbasis STEM mampu memberikan peningkatan pemahaman signifikan jika diterapkan secara relevcan dengan alat peraga edukatif. Program pengabdian ini bertujuan mengevaluasi efektivitas mainan mekanikal edukatif berbasis pembangkit listrik tenaga air untuk meningkatkan pemahaman peserta didik tentang konsep kelistrikan serta kompetensi guru dalam pembelajaran berbasis STEM. Menggunakan pendekatan Asset-Based Community Development (ABCD), program ini memanfaatkan potensi lokal untuk mendukung keberlanjutan kegiatan. Tahapan program meliputi identifikasi aset, pelatihan guru, implementasi alat peraga, serta evaluasi hasil. Sebanyak 30 peserta guru mitra dilibatkan sebagai subjek dalam program ini. Hasil evaluasi menunjukkan peningkatan signifikan pada pemahaman peserta didik (rerata nilai pre-test 60 meningkat menjadi 85; p 0,01) setelah penggunaan alat peraga. Kompetensi guru dalam merancang dan menerapkan pembelajaran berbasis STEM juga mengalami peningkatan substansial, terutama dalam memahami konsep STEM, merancang pembelajaran, serta menggunakan alat peraga secara efektif. Program ini menunjukkan bahwa mainan mekanikal edukatif mampu meningkatkan keterlibatan kelas, pemahaman konseptual, serta kepercayaan diri guru dalam mengintegrasikan STEM ke dalam kurikulum. Namun, diperlukan pendampingan berkelanjutan untuk mengoptimalkan penggunaan alat dan meningkatkan kualitas perangkat. Hasil program ini diharapkan menjadi model yang dapat diadaptasi di sekolah lain untuk mendukung transformasi pembelajaran abad ke-21 yang lebih inovatif dan inklusif.

Abstract

This research aims to analyze the performance of oil-water separation using a hydrocyclone-bubble generator. The bubble generator used was an ejector type to make it easier to suck in atmospheric air. The research was carried out by injecting an oil-water mixture through a bubble generator before entering the hydrocyclone system. The air flow injected into the bubble generator was varied from 0.1-1.5 lpm. From experimental studies, it was found that as the air flow increased, the split ratio also increased. The pressure drop at the overflow increases gently while the underflow pressure drop increases significantly along with increasing input air flow. The greater the input air flow, the more significant the difference in underflow and overflow pressure drop. It has implications for a larger pressure drop ratio. The greater the air flow, the greater the overflow efficiency decreases, and the underflow efficiency increases. The highest efficiency in overflow is 87.77%.

Abstract

Casting is the process of manufacturing molten metal with a mold to produce a shape close to the original shape. The commonly used molding sand is mountain sand, river sand and silica sand. This research aims to analyze defects and tensile test results of castings with various types of sand (beach sand and silica sand) and types of aluminum (ADC 12 aluminum and aluminum from waste cans). The casting method used is traditional sand blasting. The results show defects in the form of surface hardness, rat tails, shrinkage cavities, and pinholes. The tensile test showed that the highest Ultimate Tensile Strength (UTS) value was obtained from a mixture of Al ADC 12 with beach sand with an average UTS value of 172.44 MPa.
