Alkali-surfactant-polymer (ASP) flooding is very promising chemical enhanced oil recovery (EOR) technology which can make an incremental oil recovery factor (IORF) of 30% original oil in place (OOIP). How to choose alkali in ASP flooding remains a question for a long time. As the world’s only and largest ASP flooding application place, Daqing Oilfield has always adhered to the strategy of parallel development of strong alkali ASP flooding (SASP) and weak alkali ASP flooding (WASP), but SASP is in a dominant position, indicated by more investments and more project numbers. This leaves an impression that SASP is better than WASP. However, WASP is drawing more interest than SASP recently. Moreover, as the ASP flooding in Daqing went from field tests to commercial applications since 2014, how to comprehensively consider the benefit and cost of ASP flooding has become a new focus at low oil prices. This paper compares two typical large-scale field tests (B-1-D SASP and B-2-X WASP) completed in Daqing Oilfield and analyzes and discusses the causes of this difference. The injection viscosity and interfacial tension (IFT) for the two field test areas are substantially equivalent under the conditions of Daqing Oilfield, and WASP is better than SASP when reservoir geological conditions are considered. WASP exhibits the same IORF of 30% as SASP while having a much better economic performance. For the SASP field test, the injected strong alkali NaOH makes the test behave unlike a typical strong ASP flooding due to the presence of CO2 in the formation fluid, which well explains why IORF is much higher than all the other SASPs but scaling is less severe than others. This paper confirms that under Daqing Oilfield reservoir conditions, it is the alkali difference that caused the performance difference of these two tests, although some minor uncertainties exist. WASP is better than the SASP providing the same conditions . In addition, the detailed information of the two ASP field tests provided can give reference for the implementation of ASP flooding in other oilfields. After all, the study of ASP flooding enhanced oil recovery technology under low oil prices requires great foresight and determination.

This study aims to 1) find out the steps in developing Panlintarmatika learning media, 2) know the feasibility of developing Panlintarmatika learning media based on experts.  This study is a type of Research and Development (RD) research using the Borg and Gal model which consists of: (1) research and information collecting, (2) planning, (3) developing preliminary from a product, (4) prelimunary field testing,  (5) main product revision, (6) main field testing, (7) operational product revision (8) operational field testing.  The trial subjects used were 18 grade 2 students and teachers at SD N Kalangan.  Data collection techniques in the form of observation, interviews and questionnaires.  Data analysis includes quantitative data analysis and qualitative data analysis.  The results showed that the validation of the media experts received a score of 60 in the "Very good" category, the validation of the material experts received a score of 42 in the "Good" category and the learning expert received a score of 60 in the "Good" category.  The results of the small-scale field test students get a score of 100 with the category "Very Good" and the teacher gets a score of 94 with the category "Very Good".  Large-scale field test results students get a score of 100 with the category "Very Good" and the teacher scores 98 with a score of "Very Good" It can be concluded that the Panlintarmatika learning media is feasible and can be used as class 2 learning multiplication material

This research belonged to research and development with model of procedural descriptive that outlined the steps which should be followed to create a product. The development of web-based soccer skills test application were done in 5 steps, namely: (1) undertaking pre-study and information collection, (2) developing design of initial product, (3) expert validation and revision, (4) small-scale field test and product revision, (5) large-scale field test and final product. The subjects of this research and development were material expert, media expert and coaches of soccer school of Yogyakarta Province (DIY). The instrument of this research were questionnaire and observation. The result of this research was a web-based soccer skills test application was produced that contained main menu, namely: (1) Home, (2) menu of test guide and the conversion of result of soccer skill test which could be inputted individually or by Excel data, (3) the test application consisted of 7 items of soccer skills, that were: test of dribbling, passing-control, shooting, long-passing, juggling, heading, (4) menu of administrator’s contact.
