<![CDATA[Peanuts or Latin Arachis hypoghea is one of the crops of palawija that has long been known to our farmers as a production plant. One of the causes that inhibits peanut productivity is because the planting process is still done manually using human power. To overcome this, the system was designed to design a tool for planting peanuts mechanically. The design of this equipment begins with the size and shape of the instrument itself with the aim of producing a peanut plant that works in human thrust strength, this study brings significance to farmers to save costs to pay workers, otherwise farmers work efficiently and effectively.]]>

<![CDATA[The handicraft industry is one of the industrial sectors that provides a major contribution to the community's economy. Creative industries have 14 sectors according to the provisions of the KBLI (Indonesian Business Field Book Classification). This research was conducted in the Kluet Sub-district of South Aceh by mapping the creative industries in the Kluet Sub-district of South Aceh on the economic impact of the community which is influenced by 4 indicators namely labor, capital, total production and income. South Aceh Kluet Subdistrict is dominated by one sector, namely the Used Tires Rubber craft sector. To determine the development and influence of the creative industry on the economy, productivity is measured by making a ratio between effectiveness (output) and efficiency (input). The results of the assessment of each indicator by comparing 2018 and 2019. There is an increase from the previous year, meaning that the greater the value of productivity, the better the achievement target. Productivity measurement of the results obtained is based on labor indicators in 2018 obtained capital value in 2018 gained Rp1.4 and in 2019 amounted to Rp 1.9. There is an increase from the previous year, meaning that the greater the value of productivity, the better the achievement target. Productivity measurement results obtained are based on labor indicators in 2018 obtained productivity values of 3 units / person in 2019 amounted to 5 units / person, the above results show an increase from 2018 to 2019. This means that the effectiveness of achieving quality levels of efficient use of resources has increased. The results above indicate an increase from 2018 to 2019. This means that the effectiveness of achieving the quality level of the efficient use of resources has increased.]]>

<![CDATA[The eruption of Mount Sinabung in 2010 caused bursts of volcanic ash particles into the atmosphere layer to impact the weather. This is because volcanic ash is hydrocopic which can cause condensation process and block the process of solar radiation earth surface. Precivitable Water vapor (PWV) as one of the parameters of the atmosphere that can be used as information to determine the weather conditions in an area. Utilization of data Sumatran GPS Array (SUGAR) and data satellite Terra sensors MODIS (Moderate Resolution Imaging Spektroradiometer) can be used to find out PWV through GPS inversion method by utilizing estimated estimation of slowing and rotating GPS signals overlaid with troposphere. While the transmittance method is performed by comparing the surface reflectance between the channel absorption and the channel non absorption contained in the sensor MODIS. The results showed that spatial variation of PWV distribution pattern showed wetness pattern during eruption. This was indicated by some areas that have PWV distribution pattern almost in each region and PWV verification result from GPS showed ± 47.65 mm-66.81 mm, while PWV value from MODIS ranges from ± 13.02 mm - 80.05 mm. Based on the results of PWV-GPS correlation test from June to October of 2010 has a correlation coefficient of 0.0173 to PWV from MODIS and explains the positive relationship between PWV of GPS with PWV value from MODIS, but correlation value of the variable variables including low category because of location points Station SUGAR are spread unevenly and are more likely to spread along the western coast of Sumatra, which borders the Indian Ocean.]]>

<![CDATA[Indonesia as a country with 255,182,144 people (Central Bureau of Statistics, 2015) with the number of smokers reached 46.16 percent in the third rank with the largest number of smokers in the world after China and India, there are some elements in cigarettes one of them is nicotine, it will be one of the addictive additives. It's why smokers want to continue smoking cigarettes on a regular basis. It bounds to the brain receptors and in other organs. Increased activity in the orbitofrontal area of the cortex occurs when a smoker wants a cigarette, while in the prefrontal cortex experiences an increase in activity when smokers smoke cigarettes. Increased activity in the area will produce electrically along the scalp that can be measured using Electroencephalography (EEG). The voltage difference of the ion current will give the addiction level information to the cigarette so it can be classified. Classification is done in 4 classes namely low dependence, Moderate dependence and high dependence. From the results of the study we found that the level of brain activity of the frontal cortex increased. 52% of the 40 sampled data showed the highest increase in activity by reaching 53.17% in the highly dependent addiction category.]]>

<![CDATA[Marble is a natural rock product that is widely used in daily life. There is a lot of marble powder as a by-product during the production process. This powder can be converted into valuable items. To transform this by-product to be economically valuable items, there is a way to propagate composite products from marble powder and resin. There are four composite mixing ratios carried out in this research, namely 50/50%, 40/60%, 30/70%, and 20/80%. The mixing composites test shows bending strength and elasticity of the composite material.]]>

<![CDATA[Steel as one of construction materials has several advantages compared to other construction materials. One of the advantages is it can withstand large tensile loads compared to wood and concrete. This research was conducted to find out the strength of the connection of two-faced steel plate tension member with bolts connection through experiment and compare it with theoretical calculations by using Allowable Stress Design (ASD) method. The focused structure is a two-faced connection tension member that is connected using bolts. Steel plated that used in this research are 8 mm and 10 mm thickness with bolt sizes Ø ¼ ", Ø 3/8" and Ø ½ ", each connection using three bolts as connector. The testing of the tension member connections in the laboratory is carried out by gradually loading the tensile load until the tensile member reaches the ultimate load. The results of experimental and theoretical research found that theoretical calculation of tensile strength smaller than tensile strength done experimentally.]]>

<![CDATA[The purpose of the research was to characterize diamond-film coating which is used as carbide tool coating material, especially coating material (diamond-film CVD) and substrate material (WC/Co) in general approach interaction of chemically, This is related to the research which reported about the functional failure of carbide tool coating material, used in dry machinery process of non-ferro metal in the initial wear. The study on the characteristics of tool diamond-film coating was conducted through chemical interaction approaches which occurred between the working object and tool through dry machining process. Cutting condition was v= 350 m/min; f= 0.15 mm/put; a= 1.5 mm in Initial-wear phase (tc= 1.736 min). The result of the test was abrasive wear VB = 0.070 mm. Chemical load was tested through micro analysis using energy dispersive analysis X-Ray spectroscopy (EDAX), the result of the test was the distribution of diamond-film coating elements in aluminum 6061 testing material on the cutting conditions indicated that diamond-film coating material was still significant. The conclusion of the study was that by using chemical interaction approaches, was no coating delamination in diamond-film coating of carbide tool. The phenomenon of the three approaches was the gradual disappearing of a part of the volume of diamond-film coating material which layered substrate material as the result of abrasive-coating wear.]]>
