Abstract

Penggunaan material organik dalam komposit mengalami perkembangan yang sangat menarik. Kondisi ini tidak dapat dipisahkan dari semakin menguatnya isu lingkungan. Pembatasan penggunaan bahan-bahan yang dapat mencemari lingkungan harus dilakukan untuk menjaga itu keberlanjutan. Partikel yang dilepaskan dari komposit, sebagai debris keausan harus aman untuk kesehatan dan lingkungan. Kontribusi penelitian ini adalah eksplorasi material ramah lingkungan untuk aplikasi kampas rem di bidang otomotif. Penelitian ini menggunakan partikel bambu dan seng sebagai filler, serat kaca sebagai penguat komposit, dan epoksi sebagai matriks yang mengikat semua itu gabungan material. Pembuatan sampel dilakukan dengan menggunakan kompaksi dingin dengan tekanan yang berbeda-beda, yaitu 20, 30, dan 40 MPa. Proses selanjutnya adalah curing dengan memanaskan sampel di dalam oven listrik pada suhu 150 °C selama 1 jam. Hasil ekperimen menunjukkan bahwa kompaksi memiliki pengaruh signifikan terhadap performa komposit yang dihasilkan. Pada tekanan kompaksi 20 MPa menghasilkan densitas 1,58 g/cm3, kekerasan 15,30 BHN, dan laju keausan 6,16 x 10-6 g/mm2.s. Pada tekanan kompaksi 30 MPa menghasilkan densitas 1,62 g/cm3, kekerasan 16,33 BHN, dan laju keausan 5,66 x 10-6 g/mm2.s, sedangkan pada tekanan kompaksi 40 MPa memiliki densitas, kekerasan dan laju keausan masing-masing adalah 1,66 g/cm3, 17,67 BHN, dan 5,48 x 10-6 g/mm2.s. Densitas, kekerasan, dan ketahanan aus material mengalami peningkatan seiring dengan tekanan kompaksi pada saat proses manufaktur.

Abstract

Roof tiles play a vital role in the construction industry by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

Vocational education requires teachers to possess professional competencies that are relevant to industrial developments, including skills in weld inspection. However, most vocational high school (SMK) teachers still face limitations in understanding inspection procedures based on international standards. This condition creates a gap between the teaching process and the needs of industry, which emphasizes weld quality. Therefore, a systematic training program is needed to improve the quality of welding instruction in vocational schools. This activity aimed to strengthen the competencies of vocational school teachers in conducting weld inspections according to the American Welding Society (AWS) standards. The methods included needs assessment, delivery of theoretical materials, practice of visual inspection and non-destructive testing (NDT), as well as process and outcome evaluation. The training was implemented in a participatory manner through a combination of lectures, discussions, and hands-on practice with experienced instructors. The results indicated that teachers gained better conceptual understanding of weld inspection standards. Moreover, their technical skills in visual inspection and the application of NDT methods improved significantly. Process evaluation showed active participation and high enthusiasm among participants, while outcome evaluation demonstrated high levels of satisfaction with the instructors’ competence and the relevance of the materials to school practices. Overall, the training effectively bridged teachers’ competency gaps and enhanced the relevance of vocational learning to industry standards.

Abstract

The electrical topic is considered a material that is difficult to understand because electricity is a substance that is not seen but can be felt. The objectives of this study were 1.) to develop digital textbooks for basic electricity materials based on problem-based learning; 2.) to analyze the feasibility of digital textbook products for basic electricity materials based on problem-based learning. This research is development research using the 4D model, namely define, design, develop, disseminate. This study involved language, material, and media experts in validating research products. The research subjects were students of technical engineering vocational education in one of the public universities in Indonesia who took Basic Electrical and Electronics courses, namely 25 students. The data collection technique used interviews, document analysis, and questionnaires. The data analysis technique used descriptive statistical analysis. Based on the research results that have been done, it has resulted in several conclusions, namely; 1.) Development of digital textbooks on basic electricity materials based on problem-based learning is carried out by referring to the 4D model development steps, namely define, design, develop, and disseminate; 2.) The appropriateness of digital textbooks according to the media expert's assessment of getting a mean score of 3.61 is declared very good, the material expert's assessment is 3.52, which is declared very good, and the user response gets an assessment of 3.51, which is declared very good Theoretically developed digital textbooks are able to increase student interest and motivation to learn basic electrical materials in an easy way.
