Abstract

Abstract Training aids are the tools used to visualize something that cannot be seen or is difficult to imagine clearly, until it is clear and can lead to understanding and perception of someone. This research aims to create visual aids as educational media for technical core skill. This media is used to deliver messages (study materials), so as to stimulate attentions, interests, thoughts, and feelings of students in learning activities to achieve learning objectives. Materials and equipment used to make visual aids Fastener set consists of 5 layers mild steel plates with size 9 mm x 600 mm x 600 mm, 20 layers mild steel plates 250 mm diameter x 5 mm thick, L profile mild steel size 70 mm x 70 mm x 1100 mm, Fastener (Bolt and Nut, Hex Socket Head Bolt, 12-Point Head Bolt, Acorn Nut, Set Screw). Mild steel plates are drilled by CNC machine with variation size and then every side of it is assembled by fastener with metric size ( M6 – M20 of bolt) and imperial size ( 1/4 - 7/8 inch of bolt ). The components are assembled and tightened with torque wrench and it can be disassembled again. This method is used to improve student skill. The results showed that making visual aids fastener set can be created, works fine and can be used as a media to improve student skill and learning of technical core skill Key words: Training aids, Education media, Fastener Set, Bolt, Technical Core Skill Abstrak Alat peraga adalah alat bantu memvisualisasikan sesuatu yang tidak dapat dilihat atau sukar dibayangkan secara jelas, hingga nampak jelas dan dapat menimbulkan pengertian dan persepsi seseorang. Penelitian ini bertujuan untuk membuat alat peraga sebagai media pembelajaran technical core skill. Media ini digunakan untuk menyalurkan pesan (bahan pembelajaran), sehingga dapat merangsang perhatian, minat, pikiran, dan perasaan siswa dalam kegiatan belajar untuk mencapai tujuan belajar. Bahan dan peralatan yang digunakan untuk pembutan alat peraga Fastener Set adalah plat baja mild steel dengan ukuran 9 mm x 600 mm x 600 mm sejumlah 5 lembar, plat baja berdiameter 250 mm x 5 mm sejumlah 20 lembar, baja siku dengan ukuran 70 mm x 70 mm x 1100 mm, Fastener (Bolt dan Nut, Hex Socket Head Bolt, 12-Point Head Bolt, Acorn Nut, Set Screw). Plat baja dilubangi menggunakan mesin CNC dengan ukuran lubang yang bervariasi pada setia sisi plat tersebut. Kemudian setiap sisi ini yang telah dilubangi dipasang fastener dengan beberapa jenis ukuran baik metrik (bolt M6 sampai M20) dan ukuran imperial ( bolt 1/4 sampai 7/8). Komponen ini disusun menjadi satu kesatuan hingga membentuk Box Fastener. Fastener dapat dipasang dan di kencangkan dengan kunci torsi serta dapat dilepas kembali secara berulang-ulang guna melatih skill praktik mahasiswa. Hasil pembuatan alat peraga menunjukkan bahwa alat peraga Fastener Set dapat dibuat, berfungsi dengan baik dan dapat digunakan sebagai media untuk melatih skill praktik mahasiswa serta dapat digunakan sebagai media pembelajaran Technical Core Skill.

Abstract

The core shell structure of TiO2@SiO2@ferrite(Ni-Cu-Zn) as composite nanoparticles for magnetic photocatalyst were successfully prepared in this study. These particles were synthesized continually by the sol-gel method and they are tested for their performance using MB dye solution. The magnetic core particles used in the synthesis were (Ni-Cu-Zn) ferrite with size of 20-60 nm, while SiO2 and TiO2 layers were formed using tetraethoxysilane and tetrabutly titanate. Some characterizations and testinghavecarried out to investigate the crystal structure, magnetic properties, surface conditions and performance of these particles. The results show that the anatase crystal structure of TiO2 was obtained on the outer shell of the particle, while the magnetization value and surface area were achieved at 4.74 emu/g and 126,831 m2/g, respectively. The nanoparticles of composite size were obtained about 10 to 40 nm with the shell thickness up to 4 nm. The performance results of photodegradation was quite good for reducing MB dye up to 63.37%.

Abstract

The increasing usage of plastic is proportional to the amount of plastic waste today. The plastic usage makes the human live easier especially for packaging purposes. However, it also has a negative impact to the environment. This is due to it cannot easily decompose. Therefore, it can reduce the level of soil fertility. Besides plastic, lubricant waste from motor vehicles can induce an environmental problem as well since it is categorized of hazardous material (B3) waste. Currently, the use of plastic waste has been widely carried out by correlating into liquid fuel through thermal cracking or pyrolysis treatment. It produces liquid and it can be used as an alternative liquid fuel. This study uses the co-pyrolysis method for treating the used plastic waste with used lubricants. The composition ratios used are 10:0, 10:2, 10:4, 10:6, and 10:8. The highest acquisition of liquid products was in the composition ratio of 10:6 as much as 24.67% with a calorific value of 11015.33 cal/g. Then the highest calorific, density, and viscosity values were obtained, namely at the 10:8 composition ratio of 11061.67 cal/g, 0.8906 g/mL, and 0.927 cSt. It was concluded that the mixing of used lubricants in the co-pyrolysis of LDPE plastic waste was able to increase the calorific value of the liquid product produced.
