Abstract

The demand for increasingly diverse product designs and specifications in the manufacturing industry requires  Computer Numerical Control (CNC) machine operators to have high technical skills and strong self-efficacy and creativity. High self-efficacy allows operators to be more confident in applying their technical skills, while creativity helps them solve problems and challenges during the production process. This study aims to improve students' self-efficacy and creativity by applying the Peer-Project Based Learning (Peer-PjBL) model, which combines aspects of project-based learning with peer-to-peer learning. The method used in this research is Classroom Action Research (PTK), which consists of two implementation cycles. Each cycle involves planning, implementation, observation, and reflection stages. The subjects of this study were 20 students who took the CNC Machining Technology course at Universitas Negeri Yogyakarta. Data were collected using a questionnaire that measured self-efficacy and student creativity indicators and then analyzed descriptively. The results showed that applying the Peer-PjBL method significantly increased students' self-efficacy and creativity in each research cycle. This improvement can be seen in students' ability to face new challenges independently, as well as their ability to generate diverse creative ideas in solving problems. This research makes an important contribution to the development of learning methods in vocational education by emphasizing the improvement of technical abilities and non-technical skills, such as self-efficacy and creativity, which are needed in the modern world of work.

Abstract

This study examined within-participant changes in procedural understanding, practical welding skills, and learning engagement following the introduction of Indonesian Sign Language (BISINDO)-based instructional videos for a vocational high school student with hearing impairment. The study employed an A–B single-subject design comprising three baseline sessions and three intervention sessions. Outcomes were assessed using structured observation rubrics and converted to scores on a 0–100 scale. The participant was a student with hearing impairment enrolled in a basic welding course at a vocational high school. Data were collected through repeated observations across six learning sessions, consisting of three baseline sessions and three intervention sessions. The instruments included observation sheets assessing procedural understanding, practical welding skills, learning engagement, and intervention implementation. Data were analyzed using visual analysis across conditions and the percentage of non-overlapping data (PND) to identify changes between the baseline and intervention phases. The results indicated positive within-participant changes across all observed variables following the introduction of BISINDO-based instructional videos. All intervention observations exceeded the highest baseline observation, resulting in a PND value of 100% for each outcome. However, these findings should be interpreted with caution due to the short duration of each phase and the absence of experimental replication. For the participant in this study, the introduction of BISINDO-based instructional videos was associated with higher observed scores in procedural understanding, practical welding skills, and learning engagement. Further research employing more rigorous single-case designs with additional participants is needed before broader conclusions can be drawn.

Abstract

Pengrajin batik tulis menghadapi lamanya tahap sketsa (hingga ±3 hari) dan menurunnya minat generasi muda, yang menekan produktivitas. Kegiatan ini bertujuan memperkenalkan dan menguji Automatic Smart Pen Plotter (ASP2) sebagai solusi percepatan sketsa sekaligus penguatan literasi digital. Pelatihan praktik penggunaan ASP2 dilaksanakan pada 23 Agustus 2025 di Sanggar Batik Astoetik dengan 20 peserta, melalui tahapan hands-on, observasi, dan evaluasi kepuasan. Peserta berhasil mengoperasikan ASP2 untuk membuat pola di kain mori dan melanjutkan ke proses membatik tradisional (pencantingan, pewarnaan, nglorod), dengan percepatan nyata pada tahap sketsa dibanding cara manual. Survei menunjukkan kepuasan 100% pada aspek fasilitator, waktu, dan kemudahan penggunaan; 80% menyatakan peningkatan keterampilan dan pengetahuan yang sangat besar; dan 100% berminat mengikuti pelatihan lanjutan. Penerapan ASP2 pada mitra berdampak pada peningkatan produktivitas, penguatan kompetensi digital, serta terbentuknya persepsi positif bahwa teknologi dapat menjadi mitra dalam pelestarian batik.

Abstract

This study aims to determine the effect of alkali treatment duration with NaOH on the tensile strength and physical properties of coconut fiber-reinforced composites. The method used in this study was experimental, with variations in the duration of alkali treatment: 1, 2, and 3 hours. A total of 15 specimens were used for tensile testing. The specimens were prepared by hand lay-up, and tensile testing was conducted according to ASTM D638. The collected data were analyzed descriptively and presented in tables and graphs. The results of this study indicate that the duration of alkali treatment on fibers can affect the tensile strength and physical properties of polyester composites reinforced with coconut fiber. The results of this study show that the highest tensile strength was obtained at an alkali treatment duration of 1 hour, with a value of 19.322 MPa, and the lowest tensile strength was obtained at 2 hours, with a value of 13.826 MPa. The highest elastic modulus was observed at an alkali treatment duration of 3 hours with a value of 16.842 MPa. The lowest elastic modulus was observed at an alkali treatment duration of 1 hour with a value of 12.857 MPa. The microstructure photos were consistent with the tensile strength, i.e., the fewer defects in the fracture, the higher the tensile strength.
