Spectrum-imaging is a useful technique for comparing different processing methods on very large data sets which are identical for each method. This paper is concerned with comparing methods of electron energy-loss spectroscopy (EELS) quantitative analysis on the Al-Li system. The spectrum-image analyzed here was obtained from an Al-10at%Li foil aged to produce δ' precipitates that can span the foil thickness. Two 1024 channel EELS spectra offset in energy by 1 eV were recorded and stored at each pixel in the 80x80 spectrum-image (25 Mbytes). An energy range of 39-89eV (20 channels/eV) are represented. During processing the spectra are either subtracted to create an artifact corrected difference spectrum, or the energy offset is numerically removed and the spectra are added to create a normal spectrum. The spectrum-images are processed into 2D floating-point images using methods and software described in [1].

Islamic that mercy has been encouraging for his people, therefore Islamic concept that was delivered by Islamicpreachers has given benefit and welfare of the inner and outer life. In fact, poor Muslim population reaches23 %, while most of them have not been routinely practicing the tought of Islam. This paper aims to analyzethe competence factor of preachers (PAIF) effect on the activity of preaching; and analyze the preachingcomponents a PAIF affects to preaching effects. This research was conducted in Sleman Yogyakarta by usinga mixed method of quantitative analysis that is supported by SEM analysis techniques. The research resultsshowed that: a PAIF required to has competence in understanding the socio-cultural and communicate well sothat he can design the preaching messages that fit to the needs of targeted community. Encouraging preachingactivities can be organized through: setting the theme of preaching messages that support the needs of followers;presented by giving motivation; balancing the use of preaching methods and the preaching extension methods,as well as utilizing other forms of communication appropriately and optimally.

This chapter reviews several quantitative analysis techniques that may be applied to digitized EEG data. The technique of MEG is also discussed. Many of these techniques were primarily used as research tools; but as they have become more widely available, they are having an increasing effect on EEG interpretation and diagnosis.

Abstract We describe a system, both hardware and software, that provides quantitative analysis and data reduction of two-dimensional electrophoresis gels. Image-analysis techniques are used to determine spot intensities and to match spot patterns among many gels. A pattern-recognition program is used to extract the useful information contained in the spot lists. The application of this technology to a study of supernates from bacterial cultures is described.

Indonesia is the largest Muslim country in the world. Every Muslim must consume halal products. The trend in Indonesian society that is developing now is the hijrah trend. People change lifestyles to become more aware and concerned with the halal of a product. The hijrah trend makes halal standardization develop on food and beverages, services and lifestyle (halal cosmetics). One of the halal cosmetics sold in Indonesia is Make Over Brand Cosmetics. Make Over has been registered in the Indonesian Ulema Council as halal cosmetics that can provide security for Muslim. The purpose of this study is to analyze the direct relationship between Islamic religiosity and halal knowledge variables on the attitude and purchase intention variables. Then analyze the indirect relationship between Islamic religiosity and halal knowledge variables on the purchase intention variable that is mediated by the attitude variable. The sampling technique is purposive sampling with 185 respondents. Data analysis techniques using quantitative analysis with analysis tools SmartPLS 3.0. The results of the analysis showed a significant positive direct relationship between Islamic religiosity variables and halal knowledge on the purchase intention and attitude variables. Then there is also an indirect relationship with partial mediation by the attitude variable.

This study aimed to imrpove: (1) learning interest and (2) learning achivement of ignition system by using jigsaw. The type of this study was a classroom action research. The research subject was the eleventh grade students of class XII D of SMK Muhammadiyah Pakem in academic year 2016/2017 consisted of 31 students. The research object was learning interest and learning achivement of ignition system. Data collection techniques used questionaire and test. The research instruments wete leson plan, questionaire,  test, and observation guideline. Data analysis techniques used descriptive analysis and quantitative analysis to know the pecentage of learning interest and learning achivement of ignition system. This study shows that (1) the use of jigsaw could improve learning interest of ignition system. The score of learning interest in cycle I was 40.093 in low category improved in cycle II became 51.742 in fair category and improved again in cycle III became 58.419 in high category. (2) The use of jigsaw could improve learning achivement of ignition system. The score of learning achivement of ignition system in pre cycle was 52.74, cycle I was 65.81, cycle II was 74.19, and cycle III was 79.35. The students who were completed in learning in cycle I was 5 students (16.13%), cycle II was 23 tudents (74.19%), dan cycle III was 29 studentes (93.55%).

Indonesia's fishing capture industry has very great potential in order to become the national economy's key driver. Change in population, pricing, technology, and productivity are the key indicators of trend. The objective of this study is to assess the evolution of Indonesian fisheries. This study was carried out at the Ministry of Maritime Affairs and Fisheries from August 2020 to July 2021. According to this study, 34 provinces in Indonesia were surveyed using a literature review method. Primary data in the form of expert opinion (expert judgment) consisting of 10 capable respondents. Secondary data was adopted from statistical data of the Ministry of Marine Affairs and Fisheries Center from 2005-2018. Data analysis was performed by using descriptive quantitative analysis techniques. The development of capture fisheries competitiveness in Indonesia has experienced fluctuating changes and tends to increase during 2006 to 2018.
