Abstract

The purpose of the research is to know the length of the critical comparison of: (1) Agave fiber, (2) Kenaf fiber, (3) Palm fiber, and (4) Coco fiber. This research conducted in the laboratory of materials in mechanical engineering Universitas Gajah Mada by using quantitative methods. Population in this research are a natural fiber. The sample used the technique purposive of sampling some 4 kinds of natural fibers. The research by using a agave fiber, palm fiber fiber, kenaf fiber, coco fiber, epoxy resins, and catalyst. The sample used piece from agave fibers, palm fiber, kenaf fiber, and coco fiber. To find the critical length of each fiber using the pull out of fiber test method. Testing critical length of fibers using fiber-universal test machine. The main material that is used in the form of agave fiber, coco fiber, palm fiber, kenaf fiber, pieces of pipe, epoxy resins and catalysts. Mixing resin epoxy with a catalyst using comparison 100 % : 1 % with 100 % of resins and 1 % of catalysts. The sample used are pieces of agave fiber, kenaf fiber, palm fiber and coco fiber. To find the critical length of each fiber by using pull out fiber test methods. Before the test with pull fiber test methods, fiber pull test single advance in search of single fiber tensile strength of each fiber. Testing critical fibre length by using the tool universal fiber test machine. The analysis of the data used is descriptive analysis. Based on the result of data analysis can conclude that: (1) Critical length of agave fiber is 9 mm; (2) Critical length of kenaf fiber is 36 mm; (3) Critical length of palm fiber is 11 mm; and (4) Critical length of coco fiber is 36 mm.

Abstract

The purpose of this study was to (1) Studying the effect of adding the powder dry cellmarks the porosity defects result from remelting of Al-Si piston waste scrap, (2) Study theeffect of adding the powder dry cell marks of violence result from remelting of Al-Si pistonwaste scrap, (3) Study the percentage improvement in dry powder degasser cell as analternative to get the product to the remelting of Al-Si piston material defects former withminimal porosity.This study used an experimental method that uses a single independentvariable factors (variations addition of powdered dry cell) and two-factor variable (porosityand hardness). Objects in this study using the results of remelting of Al-Si piston waste exwith Si content of 9%. Data analysis techniques in this study using descriptive data analysis.Input parameters in analyzing the data include: the addition of  powdered dry cell variation(0%, 0.10%, 0.15%, 0.20%, and 0.30%), porosity test, photo macro structure, and violence.In this study, the addition of the powder has not found the percentage of used dry celloptimized to minimize porosity. The results showed that the remelting of Al-Si piston formerwaste occurs at 0.6909% porosity. Gas porosity increasing as a percentage of dry cellpowder was increased to 0.30 wt% Al. Highest porosity occurs in the addition of the formerpowder dry cell weight as much as 0.30% Al with porosity of 1.6226%. Based on thestructure of the macro picture shows a pore porosity. Gas porosity is caused by H2O gas. Inthe former there is a dry cell powder elements as much as 4.85 wt% H2O. Former cell drypowder only serves as hygroscopic moisture flux which acts as a binder impurities into slag.Visual condition of the specimen shows the addition of a former dry cell powders affect thecleanliness of the molten metal slag (slag) so that the surface becomes smooth look. Formerdry cell powder affect the increased hardness value. Hardness value increases with theaddition of powdered dry cell percentage of the weight of the former al. The increaseaveraged 6.21%. This is because the elements of C as much as 2.76% by weight in the d rycell powder.

Abstract

The result of this research shows that the effect the usage of heating gasoline fuel through a capillary tube which is radial finned in the upper tank radiator at engine speed 1000 r.p.m., 2000 r.p.m., and 3000 r.p.m.. Average consumption at engine speed 1000 r.p.m. normal Toyota Kijang average consumption 32,066×10-3 cc per cycle. With the use of heating fuel use 3 copper pipe with fins spaced 10 mm fuel consumption by 25,174×10-3 cc per cycle. Fuel consumption decreased by 6,892×10-3 cc per cycle or 21,58%. At engine speed 2000 r.p.m. normal Toyota Kijang average consumption 38,487×10-3 cc per cycle. With the use of heating fuel use 3 copper pipe with fins spaced 10 mm fuel consumption by 28,121×10-3 cc per cycle. Fuel consumption decreased by 10,366×10-3 cc per cycle or 26,93%. At engine speed 3000 r.p.m. normal Toyota Kijang average consumption 36,783×10-3 cc per cycle. With the use of heating fuel use 3 copper pipe with fins spaced 10 mm fuel consumption by 31,187×10-3 cc per cycle. Fuel consumption decreased by 5,596×10-3 per cycle or 15,21%. The conclusion of this research is the usage of fuel heating using three copper tubes with the range between the fins is 10 mm in the upper tank of radiator can reduce the biggest lowers fuel consumption on the Engine of Toyota Kijang 1989.

Abstract

Tujuan penelitian adalah untuk memperoleh pengetahuan mengenai  penerapan Sistem Manajemen Mutu ISO 9001:2008 untuk meningkatkan kompetensi guru Program Teknik Kendaraan Ringan di SMK Negeri 1 Trucuk.Penelitian ini menggunakan pendekatan kualitatif dengan metode analisis deskriptif. Simpulan penelitian ini adalah Pemahaman guru SMK Negeri 1 Trucuk terhadap hakikat SMM ISO 9001:2008 secara umum sudah cukup baik akan tetapi masih ada yang memahami secara parsial. SMK Negeri 1 Trucuk melalui Wakil Manajemen Mutu telah melakukan langkah sosialisasi yang tepat untuk menanamkan kefahaman guru terhadap penerapan SMM ISO 9001:2008. SMK Negeri 1 Trucuk telah menerapkan seluruh klausul ISO yang dipersyaratkan kedalam proses bisnis sekolah dan dapat dibuktikan melalui dokumen-dokumen dan rekaman kegiatan mutu. SMM ISO 9001:2008 memiliki peran yang signifikan didalam peningkatan kompetensi guru. Kompetensi Guru SMK N 1 Trucuk yang diwakili oleh dua orang sampel guru menunjukkan nilai PKG sebesar 94,4 dan 91,6 yang artinya termasuk sebutan amat baik berdasarkan tabel konversi nilai kinerja hasil PK Guru. Kendala yang muncul didalam penerapan SMM ISO 9001:2008 antara lain: ketidaksesuaian antara bidang keahlian lulusan dengan tugas mengajar di TKR, sulitnya menumbuhkan kesadaran pribadi guru untuk menjalankan SMM ISO 9001 : 2008, Karena ISO 9001:2008 merupakan merk dagang maka membutuhkan biaya yang cukup besar untuk menerapkannya. Sebagian guru yang tidak merespon dan bersikap acuh terhadap penerapan SMM ISO 9001 : 2008, dan sebagian guru senior (usia tua) yang kurang aktif dalam upaya peningkatan kompetensi dan mutu mengajarnya.
