Hubungan Efikasi Diri Terhadap Prokrastinasi Pada Santri Tahfidz Qur’an
Abstract: Prokastinasi merupakan perilaku menunda kegiatan, sehingga prokastinasi tidak patut untuk dilakukan pada santri, karena akan menghambat ketidaklancaran tugas yang dilakukan. Penelitian ini bertujuan untuk mengetahui hubuungan efikasi diri terhadap prokrastinasi pada santri tahfidz qur’an. Metode penelitian yang digunakan adalah metode kuantitatif. Alat pengumpulan data menggunakan skala efikasi diri dan skala prokrastinasi. Subjek dalam penelitian ini merupakan santri Pondok Pesantren Tahfidz Qur’an Ma’had Al Mubarok Litahfidzil Qur’an Al Karim Jambi dengan populasi berjumlah 382 santri, dan sampel sebanyak 67 subjek santri. Analisis data menggunakan korelasi product moment. Hasil penelitian menunjukkan bahwa koefisien antara efikasi diri dengan prokrastinasi adalah 0,256 dengan tingkat signifikansi 0,018 (p0,05) dan menunjukan terdapat hubungn negatif yang signifikan antara Efikasi Diri dengan Prokrastinasi

Continuous ethanol production from dilute-acid hydrolyzates : detoxification and fermentation strategy
The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. Lignocellulosic materials are available as a by-product of many industrial processes and agricultural materials, or can potentially be produced from dedicated energy crops. The production of ethanol from lignocellulosic materials includes hydrolysis which breaks the cellulose and hemicellulose polymers to fermentable sugars, followed by cultivation which converts the sugars into ethanol, and finally a separation process where ethanol purification is carried out to produce fuel ethanol. However, some byproducts such as furan compounds are released during chemical hydrolysis and inhibit the yeast during cultivation. This work contributes a solution to overcome these problems especially for a continuous process which is economically superior. Hydrolyzate detoxification using lime (â overlimingâ ) in concert with the capability of yeast to carry out in-situ detoxification is focused upon in the work. The kinetics of the overliming process were studied, where both sugars and furan compounds are degraded through a formation of complex ion. The sudden addition of lime in a batch process shows severe degradation of sugars together with furan compounds. This knowledge leads to development of a continuous detoxification process where gradual addition of lime can save 25% of the initial sugar with similar detoxification effects under certain conditions. Cell immobilization and cell flocculation have been studied to develop a high cell density system. High cell density is effective in carrying out in-situ detoxification. This study shows a good combination of continuous detoxification and cell immobilization where continuous ethanol production of 5.14 g/L·h can be carried out at a high feeding rate of 0.648 h-1. In addition, the application of a serial bioreactor has been found to increase the utilization of substrates. A gain in substrate assimilation of 11.6% has been achieved when using a serial bioreactor at residence time of 2.32 h. Furthermore, a cell flocculating system has been studied and developed. In a steady-state condition, the cell flocculation system could cultivate fresh hydrolyzates at a high feeding rate of 0.52 h-1 without any additional chemical detoxification, while sugar assimilation and ethanol productivity were 96% and 7.4 g/L·h respectively. In conclusion, this study proposes a concept of rapid continuous production of ethanol where inhibitory obstacles can be overcome by chemical detoxification and/or in-situ detoxification by yeast.I.

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
