Today, every day the community is always crammed with so many advertisements that offer various conveniences. For some advertisers, advertising through electronic media (television) becomes an attractive alternative choice, in addition to its wide reach, ad serving through television media can reach a broad target. This study has two problem formulations namely whether there was an influence of exposure milk advertising on consumer buying interest. Meanwhile, the data analysis techniques in this study were quantitative descriptive techniques and explanative techniques. This research was conducted with a sample of 60 respondents, namely members of AA 'Gym Fitness Club Indralaya in 2017 and conducted between March and June 2018. The data were collected via distributing questionnaires, observations, and documentation. Based on data analysis, the results show that gain mass milk advertisement had a significant influence on consumers' buying interest because in this study based on t value it is known that the t-count value is 3.081> ttable 2.002 so it can be concluded that the ad exposure variable influences the consumer purchase interest variable. Thus H1 is accepted and H0 is rejected. In this study, it also obtained an R Square value of 0.141. So it can be interpreted that the independent variable X (exposure to advertising) has a contribution of 14.1% to the variable Y (consumer buying interest).

Cutting Zone

Surface completion is a significant proportion of item quality since it extraordinarily impacts the presentation of mechanical parts. In CNC machining, wet cooling technique is normally applied to provide lubrication at the cutting zone to obtain good surface finish. In this system, a lot of cutting liquid is provided ceaselessly at the slicing zone to decrease the temperature between cutting instrument and work piece. Despite the fact that the cutting liquids are useful in ventures, their harmfulness can give negative effect to condition, human wellbeing and increment creation cost. Moreover, it is discovered that, solitary a limited quantity of coolant assumes their job in the cooling framework application. Therefore, an Arduino time base computerized coolant supply is created as another framework to diminish the utilization of cutting liquids. In this examination, an Aluminum Alloy was machined with CNC processing and the surface harshness is seen by utilizing this framework. As per the trial results, it is seen that the best time interim for providing and quit providing the coolant is 30 seconds with the surface harshness estimation of 1.0470 µm utilizing the shaft speed of 1200 RPM, feed pace of 100mm/min and profundity of cut of 0.4mm.This technique can reduce the cutting fluid consumption during machining operation and the improvement of the surface roughness is also obtained.
