Abstract

Marble, one of natural stone, has been widely produced since the last decade. In South Aceh, Marble stone is fabricated at Marble Production Unit that is located around Polytechnic of Aceh Selatan. The using of large-scale stone-cutting machines in Marble Production process tends to be a major noise source in Polytechnic of Aceh Selatan environment. The aim of this study is to analyze the noise level generated by Marble Cutting Machine in Marble Production Unit. The noise levels were analyzed by measuring Background Noise Level (BNL) and Sound Pressure Level (SPL). Sound Level Meter Type SL-814 was employed in the measurement. The results show that Background Noise Level measured is 53.03 dB on average. The highest Sound Pressure Level measured when the marble cutting machine was operated without workpiece is 94dB. In addition, the highest sound pressure level measured when marble cutting machine was operated with the workpiece is 96 dB. The values have generally exceeded the Threshold Noise Level allowed for education area, 55 dB. The noisy condition in campus environment would have an impact on teaching and learning processes within the Polytechnic of South Aceh.

Abstract

SEIIT stands for Susceptible (S), Exposed (E), Infected population untreated (I) and Infected population treated (IT). Infected groups consisted in two categories, untreated (I) and with treatment (IT) by presented to insulin. Susceptible shifted to exposed by gene. Prefered outcomes are mathematical models for diabetes mellitus type SEIIT, conventional type, determining breakpoint and basic reproduction number, breakpoint analysis, breakpoint stability simulation. The results were mathematical models or diabetes mellitus compartment charts/diagrams. These diagram were both analysed analitically and numerically. The analyses presented two fixed points, with desease and without desease. Each point was analysed by its basic reproduction number, analitically and numerically, at fixed points without desease Ro < 1, while the other Ro > 1. Human population at condition Ro < 1 tent to move from susceptibel from the initial standpoint and becomes stabilized at . Proportion of exposed (e) is diminishing from the starting point and stabilized at e = 0. Infected untreated dimished from the initial stage and stabilized at i = 0 . Infected with treatment (iT) was increased from initial point, diminished and stabilized at iT = 0. Human behavior when R0 > 1, susceptible (s) increased at the beginning then fluctuated, stabilized finally at . Exposed (e) lower at first then stabilized at . Untreated infected group (i) lower from initial then stabilized when .00393. Treatment group  initiate an increasing value, then fluctuated and stabilized at .

Abstract

Cyber crime continues every day that is always trying to exploit security holes that can be infiltrated. The techniques used vary greatly and the intended target can befall anyone, whether government institutions, private institutions, organizations and even educational institutions. One of the techniques used by intruders is the SQLI attack on the web server. This disorder can cause the information presented to be unavailable normally. once control of the database successfully taken over by the attacker, the data will be easily controlled and other attacks can be done against the client. In this study, an assessment of SQLI attacks on senior high schools in some ASEAN countries was conducted. The analysis was performed on the web server of senior high school in seven ASEAN countries. In this article, methods the forensic used to analyze web servers against attacks SQLI. There is still a lot of web server that vulnerable to SQLI. From the analysis obtained on average 20.86% for the type of SQLI in each country. Of the 70 samples of the website showed a study of web server with techniques SQLI is the highest risk level of 27% in Web Server Singapore and lowest risk level of 7% on a Web Server the Philippines.

Abstract

The existing nutmeg pulp herbal tea is produced from slice process which resulted with hard and big particle size of the powder. It is estimated to negatively affect the packaging process and defective product might be possible to occur when distribution taking place. Consequently, the study need to be done to produce nutmeg pulp herbal tea with small particle size of the powder using shredding method and define one of its substance quantity, Vitamin C as the comparable data towards the existing nutmeg pulp herbal tea product. The study reveals that the tea powder produced from shredding method is greatly smaller than slice method. Idiometri titration analysis of 5 nutmeg pulp herbal tea produced from shredding method samples shows that the average quantity of Vitamin C quantity is less significant than slice method which is only 3.514%. Thus, shredding method produces small particle size of nutmeg pulp herbal tea powder and containing less Vitamin C.

Abstract

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. Its 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.

Abstract

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.

Abstract

Bulletproof vests are outer clothing commonly used to protect military personnel from projectile attacks and explosion material distributions. In this study the bulletproof vests were made of composite particles composed of an epoxy matrix with a Hollow Glass Microsphere (HGM) amplifier and carbon fiber. The study was conducted by doing simulation analysis using Finite Element Method in accordance with NIJ (National Institute of Justice) of American Standard 0101.06 for class IIIA weapons category. The thickness of bulletproof vest was varied from 1 to 20 mm in order to obtain the optimal thickness. After obtaining optimal thickness of the bulletproof vest, then verification with experimental will be done to validate the simulation result. The results showed that the increase in the thickness has increase the toughness and rigidity of a bulletproof vest. A bulletproof vest with a thickness of 20 mm able to absorb bullet energy of 348.27 Joule and kinetic energy which passed the body of 138, 77 Joule with a penetration depth of 5.54 mm. Thus, it has met the NIJ Standard 0101.06 standard of U.S. The energy passed to the body is smaller than 170 Joule.

Abstract

The scholarship is one of the funding schemes of study in an education system. Various models and names of scholarship schemes are offered on terms that have been determined by the scholarship provider. The essence of these conditions is the trust and confidence of the funders of the scholarship recipients and is projected to complete the study period as per the allocated funds. In general, funders are very concerned about the issue of academic qualification as one of the main indicators. However, for prospective students who wish to pursue higher education from coming from orphaned families and from less financially qualified families, with good academic qualifications, not yet a parameter in the selection process of scholarship recipients. Based on this fact, this problem would like to find solution in this research and submitted the selection model of scholarship with fair decision approach. This study aims to design a fair decision-making system as a tool for selection of scholarship recipients that prioritize the values ​​of justice by prioritizing scholarship recipients from among orphans and poor. This research proposes two methods: Fuzzy Mamdani and weighting method, with 4 input parameters which are used as variables: children status and economic level, residence condition, children achievement and family dependent. Simulation testing performed by considering the parameters set is a more effective and efficient decision model for the prospective scholarship recipients. To obtain a competent recipient, then the screening process by ranking to be declared passed the selection and received as the recipient of scholarship in accordance with the number of quotas provided. This selection model becomes an alternative and provides opportunities for orphans and the poor to continue higher education and improve the human resource index as well as meet national education goals.
