Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh sistem saluran pada cetakan permanen terhadap struktur mikro dan kekerasan hasil pengecoran aluminium. Penelitian dilakukan dengan membuat tiga sistem saluran. Metode yang digunakan dalam penelitian ini adalah eksperimen. Analisis data yang digunakan menggunakan analisis deskriptif. Data yang diperoleh dari hasil pengujian berupa angka atau bilangan disajikan dalam bentuk tabel dan grafik, sedangkan data berupa gambar disajikan dalam bentuk tabel dan dideskripsikan berdasarkan hasil analisis yang dilakukan. Hasil pengamatan struktur mikro menunjukkan model B memiliki struktur lebih halus dari model A, dan model C memiliki struktur paling halus diantara model A dan B. Hasil pengujian kekerasan vickers menunjukkan model saluran A memiliki nilai kekerasan yang paling tinggi yaitu 100,4 VHN. Penuangan logam cair dalam waktu sesingkat mungkin akan mempengaruhi panjang alir dan proses pembekuan. Semakin cepat logam cair memenuhi rongga cetakan maka proses pembekuan akan semakin cepat, dan nilai kekerasan semakin tinggi. Kata kunci : Pengecoran, Aluminium, Sistem Saluran, Struktur Mikro, Kekerasan

The aim of this study was to implement the competency certification test for vocational students of light vehicle engineering program by LSP-P3 in Banyumas, which covers aspects of context, input, process, product and thoroughly. This research was conducted in four vocational schools in Banyumas. The population was 16 assessors. All member of the population was used as the sample of this research. The instrument used a questionnaire. The validity test with the content validity of the CVR (content validity ratio), the validity of items with a limited test and product moment analysis was performed. Cronbach alpa was used as the reliability test of this research. The data analysis techniques used a descriptive analysis. The description of the data used a level category approach. The results showed that the implementation of competency certification test for vocational students of light vehicle engineering program by LSP-P3 in Banyumas evaluated from the aspects of: (1) context included in the excellent category with a quality achievement score of 41.63 or (86.7%) ; (2) input included in the excellent category with a quality achievement score of 55.18 or (86.23%); (3) process included in the excellent category with a quality achievement score of 37.50 or (85.23%); (4) product included in the excellent category with a quality achievement score of 27.44 or (85.74%); and (5) as a whole included in the excellent category with a value of achievement quality results of 161.75 or (86.04%). The implementation of competency certification test for vocational students of light vehicle engineering by the LSP-P3 in Banyumas needs to be improved optimally although it has been going very well. This implies that the implementation of the competency certification test must consider the competency of the assessor. The implementation of competency certification test should use equipment that is in line with current technological developments. The competency certification test should be carried out in stages to complete the whole scheme so that graduates get a level 2 SKKNI competency certificate.

Abstract

Teaching Factory program in the field of motorcycle service which is developed in SMK Bina Utama Kendal is quite well. However, it does not train students to gain practical experience in applying entrepreneurship. Students have not been involved in the planning, organizing, monitoring, and evaluating stages in the teaching factory program. This research aims to develop the management model of teaching factory programs that increasing student entrepreneurship in the field of motorcycle engineering and business competence.  This research use R&D methodology. The research procedure consists of (1) Introduction, (2) Developing Model, (3) Testing Model. The result of the study shows the management's last model in teaching factory program is valid, effective, and easy to use. It can be used to develop student entrepreneurship based on significant results between pretest and post-test. The model which is developed in this research use entrepreneur real concept by asking students directly and giving responsibility to start from planning, organizing, conducting, evaluating in teaching factory management. This model develops students entrepreneurship such as discipline, hard work, creativity, a sense of collaboration, honest, and goal-oriented. Furthermore, it increases student's knowledge and ability in the field of motorcycle engineering.

Abstract

Kebutuhan energi yang terus meningkat berdampak pada peningkatan polusi lingkungan saat ini. Oleh karena itu perlu adanya inovasi baru untuk mengatasi masalah tersebut dengan penggunaan mesin konversi energi terbarukan berupa turbin angin sumbu vertikal (TASV). Salah satu faktor yang mempengaruhi kinerja turbin angin adalah jumlah sudu dalam turbin tersebut. Variabel yang digunakan pada penelitian ini yakni variasi jumlah sudu (2 sudu, 3 sudu, dan 4 sudu) dan kecepatan angin (4,2 m/s, 5,2 m/s, 6,2 m/s, dan 7,2 m/s). Hasil penelitian menunjukkan bahwa turbin heliks Gorlov paling optimal dengan nilai koefisien daya (CP) tertinggi yaitu turbin dengan empat sudu. Hal ini disebabkan karena semakin banyaknya jumlah sudu dan semakin meningkatnya kecepatan angin menyebabkan semakin besar gaya dari angin yang mengenai turbin setiap waktunya, sehingga gaya yang dihasilkan juga meningkat dan menyebabkan dayanya juga meningkat.

Abstract

Evaporation boat waste contains Boron Nitride (BN) and Titanium Diboride (TiB2) so that it has electrically conductive properties with high resistance to chemicals and heat. In addition, the combination of these materials has high thermal conductivity properties with a melting point of up to 2700oC and has an oxidation resistance of up to 1000oC so it is very suitable if applied to crucibles, or refractory. The purpose of this study was to determine the effect of mixing duration on the hardness of the crucible material made from a mixture of evaporation boats waste, kaolin and fire mortar SK-34. The mixing process of evaporation boats waste, kaolin and refractory cement is carried out using a mixer machine with a duration of 30, 60 and 90 minutes. The compaction process was carried out on the mixture with a force of 40 kg/cm2 to produce a cylindrical test specimen. After seven days, the specimens were sintered at 1000oC for 2 hours. The hardness test process was carried out with the FM-800 microhardness tester machine to determine the effect of mixing duration on the final product hardness. The highest hardness of 37,2 HV was found in the final product with a mixing duration of 90 minutes. The hardness of final product is increasing with an increase in mixing duration.
