Research highlights the importance of potato crop, which occupies a prominent food and economic status in food security besides rice, wheat and corn at the local and global level. Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato productivity remains substandard, this may be due to a lack of knowledge of the most efficient varieties and not to use productive resources at the levels at which technical, specialized and economic efficiency is achieved. Therefore, the aim of the research is to determine the technical, specialized and economic efficiency according to the cultivated seed category. The data envelope analysis (DEA) method was used to estimate technical, specialized and economic efficiency, assuming constant and variable capacity returns. As a result of the study, the Safrana variety achieved the highest average technical efficiency according to the stability of the yield and capacity efficiency in addition to achieving the highest average specialized and economic efficiency, The Lapadia variety achieved the highest average technical efficiency, assuming that capacity returns have changed. Therefore, we recommend the adoption of items that achieve higher efficiency and the need to redistribute the elements of production better and Achieving the optimum levels at which technical, specialized and economic efficiency is achieved and saving what has been wasted.

Al Washliyah merupakan satu di antara banyak organisasi Islam yang menolak paham dan gerakan terorisme di Indonesia. Artikel ini mengkaji respons Al Washliyah terhadap terorisme. Kajian ini menarik dilakukan, sebab organisasi ini memiliki pengikut yang fanatik dan mengelola amal usaha yang banyak, tetapi masih relatif jarang diteliti oleh para peneliti. Kajian ini merupakan studi lapangan (library research) dimana sumber datanya diperoleh dari kegiatan wawancara dan studi dokumen. Data dianalisis dengan menggunakan metode analisis data menurut Miles dan Huberman: reduksi data, pemaparan data, dan penarikan kesimpulan. Didasari dengan teori Matusitz, Pranawati, dan Golose tentang doktrin terorisme dimana gerakan ini ingin mendirikan negara Islam, memaknai jihad sebagai perang, anti terhadap non-Muslim, dan melegalkan bom bunuh diri, kajian ini akan menelaah respons Al Washliyah terhadap empat persoalan tersebut. Kajian ini mengajukan temuan bahwa Al Washliyah menolak paham dan gerakan terorisme yang muncul dan berkembang di Indonesia, dan para ulamanya menilai bahwa kaum teroris telah salah dalam memahami ajaran Islam. Temuan kajian ini dapat berkontribusi bagi pemerintah dalam upaya menanggulangi gerakan terorisme di Indonesia. Al Washliyah is one of Islamic organizations that rejects the concept of terrorism in Indonesia. This article examines Al Washliyah's responses to terrorism. This study is interesting because this organization has fanatic followers and manages many business charities, but rarely investigated by researchers. This research is field studies where the data sources obtained from the interviews activities and document studies. Data were analyzed by using data analysis method according to Miles and Huberman: data reduction, data display, and conclusion. Based on the theory of Matusitz, Pranawati, and Golose about terrorism doctrine in which the program wants to establish an Islamic state, interpret jihad as war, anti to non-Muslims, and legalize suicide bombings, this study will examine the Al Washliyah's responses to those four issues. This study proposes that Al Washliyah rejects the concept of terrorism which appears and develops in Indonesia, and ulama consider that terrorists have misunderstood on Islamic concept. The findings of this study may contribute to the government in combating terrorism movement in Indonesia.

Using Data

PD. Asia Agung Pontianak is the only official distributor of Ajinomoto in the West Kalimantan region. Every year this company needs to find out the amount of turnover that will be obtained in the coming year. Unfortunately, the company only makes predictions using the average income from each year which is very less accurate. This research is conduct to create visualizations and predictions using multiple linear regression methods to predict the turnover obtained in the coming year. Multiple linear regression is a regression analysis method that can use more than 2 variables in the prediction process which is divided into 2 parts, namely the dependent variable and the independent variable. The results obtained in this research are prediction results in 2019 using data from 2010 to 2018 as a basis. Prediction results show that the longer the data used the smaller the error rate obtained. The original data from the company is visualized using a dashboard on tableau software so that the data could be easier to analyze by the company.

Using Data

Soundproof tunnels and soundproof walls constructed on expressways are designed to prevent noise for the nearby surrounding residential areas. These soundproof walls and tunnels feature excellent noise prevention for residential areas nearby, but they hamper the dispersion of air pollutants generated, thus promoting the creation of heat islands during summer and cold islands during winter.The computational fluid dynamics (CFD) analysis method was used to investigate the wind flow around soundproof tunnels. The wind angle and the size of the wind velocity were determined using data from weather stations near soundproof tunnels. The CFD analysis results of the soundproof tunnels on expressways revealed that the wind velocity decreased by 30–60% following the installation of soundproof tunnels.

ABSTRACT Using an oil chemical analysis method developed in our laboratory, more than 280 compounds in the Alberta Sweet Mixed Blend (ASMB) oil have been positively identified. The distribution of selected target compounds offers unique and sensitive fingerprints for matching the source of spilled oil and tracing the weathering process of oil in the environment. The pattern recognition plots involving more than 100 oil-specific individual components and component groupings permit deduction of a best set of values for oil exposure to weathering. Using data from different samples including crude oil, weathered oil, and 22-year-old spilled oil as examples, the distinct advantages of the described method over the current methods are examined.

Offset Frequency

A nontrivial phase noise analysis method is proposed for frequency synthesizer of a passive millimeter-wave synthetic aperture interferometric radiometer (SAIR) imager for concealed weapon detections on human bodies with high imaging rates. The frequency synthesizer provides local oscillator signals for both millimeter-wave front ends and intermediate frequency IQ demodulators for the SAIR system. The influence of synthesizer phase noise in different offset frequency ranges on the visibility phase errors has been systematically investigated with noise requirements drawn, and the integrated RMS phase error could represent uncorrelated phase noise effects in the most critical offset frequency range for visibility error control. An analytical phase noise simulation method is proposed to guide synthesizer design. To conclude, the phase noise effects on SAIR visibility errors have been concretized to noise design requirements, and good agreements have been observed between simulation and measurement results. The frequency synthesizer designed has been successfully in operation in BHU-2D-U system.
