Abstract

The potential for waste of oil palm wood from company plantations and community gardens after passing its productive age is very large, as well as the waste resulting from processing oil palm in the form of empty fruit bunches. The need for natural wood should be reduced by using wood substitute materials, one of which is wood plastic composite, which uses plastic as a matrix and wood as reinforcement. In order to obtain a hybrid composite with reinforces in the form of palm sawdust and empty bunch fiber as well as a polypropylene matrix with mechanical and physical properties that meet the standard criteria, composite manufacture and characterization were carried out.

Abstract

Computer-aided design (CAD) is one of the competencies taught to vocational students. The software commonly used is Auto CAD, which focuses on constructing two-dimensional (2D) drawings. AutoCAD can also create three-dimensional (3D) drawings, but its features are limited. Based on these conditions, through community service activities, Politeknik Kampar improves the competence of students of SMK Negeri 1 Bangkinang Kota, Department of Mechanical Engineering. This activity aims to strengthen the CAD competence of vocational students using Solidworks software. The results of the training activities show the level of success with indications of a positive response from the participants and the participant's understanding of the material being taught. Computer-aided design (CAD) merupakan salah satu kompetensi yang diajarkan kepada siswa smk. Software yang biasa digunakan adalah Auto CAD yang fokus pada konstruksi gambar dua dimensi (2D). AutoCAD juga dapat digunakan untuk membuat Gambar tiga dimesnsi (3D), tetapi fiturnya sangat terbatas. Berdasarkan kondisi tersebut, Politeknik Kampar turut serta dalam meningkatkan kompetensi siswa SMK Negeri 1 Bangkinang Kota, Jurusan Teknik Pemesinan melalui kegiatan pengabdian kepada masyarakat. Tujuan kegiatan ini adalah untuk meningkatkan kompetensi CAD dari siswa smk menggunakan software Solidworks. Hasil kegiatan pelatihan menunjukkan tingkat keberhasilan dengan indikasi adanya adanya respon yang positif dari peserta serta pemahaman peserta terhadap materi yang diajarkan.

Abstract

The sprocket and chain transmission system was used to transmit the rotating force that occurs between two shafts where they can reach it. The sprocket and chain transmission system transfers a movement from the driving source to the moved object. If the maintenance of the sprocket and chain transmission system is carried out only occasionally, the sprocket and chain may cause misalignment. That can affect the machine's performance and cause a breakdown of the machine's components. This study aims to determine the effect of misalignment on the electric current usage and shaft rotation speed in the sprocket and chain transmission system. The leading equipment used in this study is a sprocket and chain alignment kit, while the auxiliary equipment used are ampere meter, tachometer, and other equipment. Measurements of electric current and shaft rotational speed were carried out with a variation of misalignments. The study results show that the increase in the misalignment causes a higher electric current. As for the effect of misalignment on shaft rotational speed, the rise in the misalignment causes the post-rotational rate to lower.
