AbstractThe effect of the biomass presence on the overall circulation velocity, the linear velocities both in the riser and the downcomer and the overall gas hold-up was studied in a three-phase internal loop airlift reactor (ILALR). The measured data were compared with those obtained using a two-phase system (air—water). All experiments were carried out in a 40 dm3 ILALR at six different biomass concentrations (ranging from 0 g dm−3 to 7.5 g dm−3), at a temperature of 30°C, under atmospheric pressure. Air and water were used as the gas and liquid model media, respectively. Pellets of Aspergillus niger produced during the fermentation of glucose to gluconic acid in the ILALR were considered solid phase. In addition, liquid velocities were measured during the fermentation of glucose to gluconic acid using Aspergillus niger. All measurements were performed in a bubble circulation regime. At given experimental conditions the effect of the biomass on the circulation velocities in the ILALR was negligible. However, increasing of the biomass concentration led to lower values of the total gas hold-up.

This study aims to determine the ability of teachers to manage learning, student responses, student learning completeness with the two stay two stray learning model on the material of rank numbers. The type of research used is descriptive quantitative. The sample used is class IX SMP Al-Wasilah. Data analysis used data analysis on the ability of teachers to manage learning, analysis of student response data and analysis of student learning outcomes test data. Based on the results of data analysis shows that the results of the data analysis of the average score of the ability of teachers to manage learning using the two stay two stray learning model is 4.44. The data obtained on the level of teacher ability to manage learning is in the good category. Data analysis of the average score of students' positive responses to the two stay two stray learning model was obtained at 96.4%. The positive response data obtained by students are in the category of strongly agree. The results of the percentage of students' learning completeness classically were obtained at 81.25%. Thus, the classical student learning completeness data is >80%. It can be concluded that the two stay two stray learning model is effective.

This research was conducted to determine the effectiveness of the implementation of the mentoring Al-Islam program at Universitas Islam OganKomeringIlir (UNISKI) Kayuagung which has been running so far, the implementation of the religious practice of students of UNISKI Kayuagung, and what effect the implementation of the mentoring Al-Islam program has on the implementation of the student's religious practice. This research is a descriptive field research with a quantitative approach. The data sources were students participating in the mentoring Al-Islam and the management of P5I UNISKI Kayuagung. Data collection is done using observation techniques, questionnaires, interviews, and documentation. The data analysis is done through descriptive statistical techniques. The results of the data analysis showed that the effectiveness of the implementation of the mentoring Al-Islam program at UNISKI Kayuagung based on the response data of 284 respondents to the research questionnaire using the one-sample t-test formula = 173,433> price of the table, both at the error level ( ) 5% = 1,645 or  1% = 2,362. Thus, the Ha submitted can be accepted. Meanwhile, the value of students' religious practice, using the t-test formula of one sample, the price of t arithmetic = 156.8> t table 5% = 1.645 and 1% = 2.362. The price of t arithmetic falls on the acceptance of Ha, so Ha is accepted and H0 is rejected. The statistical calculation using the product moment correlation formula shows that the application of the mentoring Al-Islam program has a positive and significant effect of 0.996 with a "very strong" relationship level on the religious practice of students of UNISKI Kayuagung.

Measure Change

Randomized response (RR) is an interview technique that can be used to protect the privacy of respondents if sensitive questions are posed. This paper explains how to measure change in time if a binary RR question is posed at several time points. In cross-sectional research settings, new insights often gradually emerge. In our setting, a switch to another RR procedure necessitates the development of a trend model that estimates the effect of the covariate time if the dependent variable is measured by different RR designs. We also demonstrate that it is possible to deal with self-protective responses, thus accommodating our trend model with the latest developments in RR data analysis.

This paper describes about the phenomenon of slang language on social network, namelyfacebook and twitter. Slang in this paper belongs to sociolinguistics study, especially sociolect. This isa descriptive qualitative method, which consists of three phase: data collection, data analysis, andpresentation of the result of data analysis. The data were collected by observing the netters utterance.Data were analysed through two phases. First, analyzing the meaning of the slang. Second, wasanalysing the categories of the slang.There are four point findings in this study. Firstly, the various forms of slang expression unitsare words and phrases. Secondly, the variety of linguistic processes forming units slang expression areby adding sound, erasing sound, changing vocal, replacing consonant, shifting sound, returning sound,repeating, and changing spell. Thirdly, the source languages of various slang reference units are fromnational language, regional languages, and foreign languages. Fourthly, the communicative functionsof various units of slang expressions are informative function, directive function, expressive function,komisif function, phatic function, and poetic function. Finally, from the finding of those four points inthis study, we know that slang language on facebook and twitter has its own uniqueness compared toother types of language.
