Molding sand is one the most important thing in sand casting. The weak tensile strength and compressive strength of molding sand causes some defects, such as sand drop and sand inclusion. Therefore this research is done by varying grain size and percentage of binder in molding sand. The purpose of this research was to analyze the tensile strength and the compressive strength of sand mold due to variation of grain size and binder presentation. Each treatment will through tensile strength test and compressive strength test, then the data from the test will be analyzed by using ANOVAfor factorial experiments with SPSS 16.0 and a significance level of 5%. From the research and analysis conducted found that the tensile strength of the molding sand is influenced by the grain size and binder presentation, meanwhile the compressive strength is influenced by the binder presentation but is not affected by the grain size. The highest average value of the sand mold tensile strength is 0.912 N/mm2 and the highest average value of the sand mold compressive strength is 2.7567 N/mm2. Those values are achieved by the use of a mixture of GFN 40-50 AFS silica with a percentage binder as much as 1.5%. Keywords: Molding sand, grain size, binder

Manufacture of biodegradable plastics in this study begins with making the dough using a single screw extruder, then the dough is molded by using a compression molding machine. The basic material used is a mixture of jatropha seed meal, corn starch, CMC (composition 7: 2: 1). This study aimed to study the effect of Helic corner and screw compression ratio of the batter character and biodegradable plastic produced. Helic screw angle was varied from 2,5o; 5o; 7.5 ° and screw compression ratio varied from 1.5; 2.5; 3.5. The results showed an increase in the angle of screw Helic simplify the process of molding (lowering the value of Tg, Tm, ΔH and texture of the dough) and to improve the mechanical physical properties of the biodegradable plastic produced (tensile strength, strain increases while the thickness and Water Vapor transmition rate decreases). Improved compression ratio increase and decrease the thermal properties of dough texture and increase the tensile strength and strain, decrease the thickness and Water Vapor transmition rate of biodegradable plastic produced.

Quality of product in various industries, especially in metal industry is the most attention so the product can compete and attract consumers. Surface roughness is one of the demand that must be fulfilled because it can be the initiation of cracks, especially when material receives recurring and fluctuating loading. Therefore, low surface roughness can produce a product with longer lifespan material. The goal of this study is to determine the most optimal combination of electroplating process with factors variety of voltage (volts), temperature (℃), and time of immersion (minutes) to produce a low values of surface roughness. This study uses an experimental design with Taguchi method. Contribution factors of control that produce the surface roughness values were influenced significantly by control factor voltage (volts) amounted to 77.31% with an average roughness value of 1.29 μm. This is due to the increase in voltage which causes the deposition of electrolyte ions which is faster in the deposition structure of the specimen. Where as other control factors were not effected significantly on the temperature control factor amounted to 4.85% with an average roughness value of 1,32 μm. These results are possible because the temperature variations used (40℃ to 50℃) are still within the optimum operating temperature. And the other control factors is immersion time amounted to 10.13% with an average roughness value of 1,32. The result ware obtained because the length of coating time affected the quantity of deposition of nickel ions on the surface of the specimen. The result of optimal condition is the voltage level 2 (6 volts), the temperature at level 2 (45℃), and the immersion time at level 3 (25 minutes).

Tangan merupakan anggota gerak tubuh bagian atas yang sering digunakan dalam berbagai aktivitas sehari-hari. Aktivitas sehari-hari manusia sebagian besar melibatkan anggota gerak tangan, misalnya menggenggam dan mengangkat. Aktivitas berat atau berlebih pada manusia dapat menimbulkan gangguan kesehatan seperti serangan stroke. Stroke merupakan penyakit gangguan fungsional akibat terhambatnya aliran darah ke otak yang dapat sembuh secara sempurna, sembuh dengan cacat, maupun dapat menyebabkan kematian. Robot tangan terapi stroke pada penelitian ini menggunakan metode simulasi dan pengukuran manual. Tahapan proses simulasi dimulai dengan pemodelan robot menggunakan Software Solidwork 2018, material yang akan digunakan (PLA), selanjutnya, analisis posision dengan simulasi Ansys 19 R1 untuk mode Rigid Body Dynamic. Tahapan pengukuran manual menjadi tinjauan utama penentu validnya penelitian karena proses simulasi digunakan untuk parameter acuan robot sebelum di cetak menggunkan printer 3D. Hasil perbandingan dari simulasi dan validasi adalah desain 1 hanya bisa menggerakkan linkage MCP sedangkan desain 2 dapat menggerakan mekanisme dari sudut MCP, PIP, dan DIP, sehingga pergerakan mekanisme desain 2 hampir menyerupai pergerakan otot jari manusia pada umumnya.
