Pembuatan Kekasaran Permukaan Material ST 37 terhadap Kecepatan Pemakanan pada Milling Machine
Get PDFOne of the ideal geometric characteristics of a component is a smooth or rough surface. In practice, it is not possible to obtain a component with a smooth/rough surface. This is due to several factors, such as the human factor (operator) and the factors of the machines used to make it. However, with technological advancements, the growing apparatus capable of forming surface components with a high degree of fineness/roughness, according to the standard measures applicable in metrology, is advanced by geometric measurement experts through research experience. Fineness level/roughness of a surface is very important role in the planning of a machine component, especially concerning the problem of lubrication friction, wear and tear, resistance to fatigue and so on. Therefore, in the planning and manufacture must be considered first about which machine equipment should be used to make it and how much the cost must be incurred. In order for the process of manufacture, there is no significant deviation, then the characteristics of this surface should be understood by the planner even more by the operator. Communication of surface characteristics is usually done in engineering drawings. But to explain perfectly about the characteristics of a surface seems difficult. The research method is started by preparing instrument that is Milling Machine which is used to make surface roughness and Surface Roughness Tester is done 3 times test with variable speed of food which is different equal to 7,3; 13; 24.5 mm/put. With a speed of 102 rpm Rpm, and a depth of 0.4. Next, determine the material roughness level with Surface Roughness Tester. After all, done will get the data test results, followed by analysis and discussion so that will get final conclusion. From the research results obtained the following results: there is a difference in the level of roughness in each material with different feeding speed. The feed rate of 7.3 mm / put yielded 0.64 μ, 13 mm / put roughness generated 1.32 μ, 24.5 mm / put yielded 3.77 μ. The process of measuring the roughness of the material with the speed of feeding is slower, the smoother the surface roughness, the faster the speed of the feeding the more rough. The range of syrup result is also influenced by the speed of the food. The faster the movement of the range range the wider the surface roughness is the opposite

Drilling mud is one of the important supports in an oil, gas and geothermal drilling operation. The function of drilling mud is determined by the chemical composition and physical properties of the mud. Errors in controlling the physical properties of mud will cause failure which can lead to drilling problems (hole problems) and ultimately result in huge losses. Viscosity is an essential part of the rheological properties of drilling fluids. Measurement of the rheological properties of drilling fluids is important considering the effectiveness of cutting removal is a direct function of viscosity. In the petroleum engineering laboratory the determination of viscosity of drilling mud is usually done using Marsh Funnel. The research aims to compare the results of the determination of viscosity using marsh funnel and video-based viscosimeter assisted by software tracker. The sample in this study was drilling mud made from aquadest and bentonite with additives added. The experiment was carried out five times with different drilling mud compositions. Sample I made from bentonite plus 0.5 gram additive spersene. Sample II made from bentonite plus spersene aditive 1 gram, Sample III made from bentonite plus aditive CMC 0.5 gram. Sample IV made from bentonite based added CMC aditive 1 gram and sample V made from bentonite without additive The results of analysis using Marsh Funnel in determining the viscosity of drilling mud where from the results of laboratory analysis if base mud was added with spersene the kinematic viscosity would decrease from 29.3 seconds to 28.3 seconds and if the base mud is added CMC then kinematic viscosity will increase from 36.5 seconds to 38.3 seconds.

In order to bridge children\u27s difficulty in learning English as a foreign language, this research was aimed to increase children’s recognize on some new English words. Learning English based on conventional method (using many words only) was compared experimentally with picture method. Seventy students grade sixth from 4 elementary schools participated in this study. Design of this experimental study was the pretest - post test. The intervention was conducted once during 75 minutes i.e. 50 minutes for exercising English words using pictures (for the picture group) and words (for the word group); 10 minutes for conducting a quiz; and 15 minutes for verifying the exam questions. It was hypothesized that the picture method was much better to increase children’s ability to recognize some new English words than the conventional method. This research revealed that children’s ability on the picture method class increased 2.5 times from the pre test compared to children in word method class (increased only 1.7 times from the pre test) and children in the control group (increased only 1.06 times from the pre test and non significant). It was recommended that teacher should use pictures to help children to understand English new vocabularies. This recommendation could also be enlarged with comic and animated film usages
