This research is a quantitative research by true experimental design. Research design is random, pre test and post test. Sample is prepared randomly by two group; experiment and control group. Experiment group is prepared by problem based learning with 13 students in this group, while control group is taught by conventional method with 10 students in this group. Tests are applied in data collecting, then analyzed by t-test. Data analysis shows at α = 0,05 there was 1,72. It can be concluded that the increase in mathematical problem solving from experiment group is relatively better than those in control group in Applied mathematics II Course in Industry Technics Study Program, South Aceh Polytechnic.

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.

Analysis of Noise Level Generated by Stone Cutter Machine A Case Study in Marble Production Unit, South Aceh: A Case Study in Marble Production Unit, South Aceh Lindawati Lindawati; Nuzuli Fitriadi; Balkhaya; Afdhal

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.

Nutmeg Pulp Herbal Tea Produced Using Shredding Method Asbahrul Amri; Devi Satria Saputra; Ria Darma

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.

Measurement of Brain Activity Rate Based on Electroensefalographical Signals on Smokers Herry Setiawan

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.

Utilization of Satellite Landsat-8 Operational Land Imager (OLI) for Land Cover Classification Nutmeg Plantation In Tapaktuan Sub-District Safridatul Audah; Nazliyati Nazliyati

Publisher : LPPM Politeknik Aceh Selatan

This research seeks to utilize technology remote sensing with satellite Landsat 8 OLI imagery by classification method to obtain the area of land cover used for nutmeg plantations in Tapaktuan Sub District. Several stages of image data processing methods have been done such as geometric correction of images, image cropping and image clsification.The result of geometric correction of image obtained RMS error of 0.011235 pixel, The geometric correction process has met the tolerance limit error > 1 pixel. As for the results of classification processing image Landsat-8 OLI year 2017 in Tapaktuan sub-district produce 6 classes land cover of nutmeg garden, mixed florest blantations,water, protected forest, settlement, and open land, the of classification results obtained by plantation area of nutmeg 4.72%, Based on the calculation of confusion matrix then obtained the overall accurasy value of 97.5714% and kappa accurasy of 96.55%. The result of classification accuracy test shows high accuracy and fulfill the requirement set by USGS (> 85%). This result shows that the map of Landsat-8 OLI image classification can be used as a material in determining the location of nutmeg plantation distribution.

Mathematics Modeling of Diabetes Mellitus Type SEIIT By Considering Treatment And Genetic Factors Asmaidi Asmaidi; Eka Dodi Suryanto
Jurnal Inotera Vol. 3 No. 1 (2018): January-June 2018
Publisher : LPPM Politeknik Aceh Selatan

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 .
