Abstract

Studies on the possible influence of physical environmental factors on extracellular b-glucanase production by Acremonium sp. IMI 383068 were undertaken, in particular to assess the role of varying agitation speed and pO2 levels, since these have been shown in other studiesto affect the yields of other fungal extracellular enzymes. The use of chemostat cultures in this present study meant that the possible influence of these two parameters on enzyme production could be controlled independently of each other and of growth rate. No other similar data on possible factors affecting fungal (1->3)- and (1->6)-b-glucanases are available in the literature, and therefore other fungal extracellular enzyme systems are used here as comparisons for this discussion. To investigate the possible relationship between enzyme production and culture morphology, the HGU values or branching frequencies of the fungal hyphae were assessed. Since substantial conidial production also occurred in these cultures of Acremonium sp. IMI 383068, it was not possible always to distinguish between mycelial branches that were true vegetative hyphae and those eventually forming the short tapered lateral conidiophores that characterize this strain. Hence HGU determinations include both of these two branch types, except where it was obvious that the branch in question was a conidiophore, adjudged by the presence of emerging conidia from it. The major findings of this study will be discused here which were mainly engaged to the relationship between production of (1->3)-b-glucanases and the growth of the fungus, where it was growth rate dependent, while that of the (1->6)-b-glucanase was growth rate independent. The production of  (1->3)-b-glucanases was shear sensitive and also depended on O2 availability in the culture medium. Based on the data from both batch and chemostat culture, it was found that there was no clear relationship between branching frequency of the fungal mycelium and b-glucanase production by the fungus.Keywords: b-glucanases, Acremonium, HGU, batch and chemostat, branching frequency

Abstract

Elections are the means to implement sovereignty of the people in order to  elect members of the House of Representatives, Regional Representatives Council, Local  Legislative  Council,  the  President  and  Vice  President.  Election  are    also meaningful for selecting the leader of the nation and the state (public officials) and as community control over board membership, President and Vice President to come. Election results are manifestation of popular sovereignty, which can lead to a dispute between organizer and election participants either political parties or individuals. The result of which can be challenged legally by election participant. The participant can also request the cancellation of the election result to the agency given with the authority to decide. Conceptually, the right institution to decide on election dispute is a special ad hoc election court. Constitutionally, dispute resolution of election result is intended to protect citizens' constitutional rights.

Abstract

The objectives of this study are to describe and create Student Worksheets based on Concept Mapping that are valid, effective, and practical to facilitate students' understanding of mathematical concepts. This research uses the Plomp research and development model that has been modified by Romadhan into 4 phases namely 1) initial investigation, 2) design, 3 ) realization, 4) tests, evaluations and revisions. The LKS was tested on a limited basis to three students of class VII A and field trials on 24 students of class VII D MTs Plus Darul Ulum. Data collection was performed using worksheet validation sheets, student response sheets, teacher response sheets, and concept understanding sheets. The results showed that the Student Worksheet (LKS) based on concept mapping to facilitate students' understanding of mathematical concepts had fulfilled valid, effective, and practical criteria. Based on the results of the validity percentage 80% and 78.13%. The results of the effectiveness based on student's responses in the questionnaire and result tests of conceptual understanding. Student worksheet effective is responses of students who meet both criteria with score Sf= 73,9% and test understanding of the concept which meets both criteria with score Sa= 80,29%. Practicability test on the student worksheet based on questionnaire responses of the teacher which meet both criteria whit score Sp= 76%. Proposition for further development, student worksheets should be developed in other topics of mathematics.Keywords: student worksheet, concept mapping, understanding of concept mathematical, algebra.

Abstract

Penyebaran wabah virus korona masih terus terjadi di berbagai negara. Indonesia adalah salah satu negara yang terpapar wabah, sehingga berdampak ke berbagai sektor kehidupan warganya. Presiden Jokowi menjawab berbagai kritikan terkait penanganan dan penanggulangan COVID-19 di Indonesia melalui wawancara khusus dengan Najwa Shibab dalam acara Mata Najwa di Trans 7 pada 23 April 2020. Dengan melakukan analisis retoris dan pendekatan restorasi citra Benoit, penelitian ini berusaha untuk melihat bagaimana strategi pesan pemerintah dalam menjawab berbagai tuduhan terkait COVID-19. Hasil penelitian menunjukkan Jokowi berusaha memoles citranya dengan melakukan beberapa strategi antara lain penyangkalan, serang penuduh, diferensiasi, kekalahan, kecelakaan, memperkuat, dan tindakan perbaikan. Jokowi dalam perbaikan citra pemerintah cenderung memakai strategi bertahana yakni memperbanyak strategi diferensiasi dan defeasibility, serta niat baik. Meski ada penyangkalan tetapi Jokowi juga menghindari menyerang para penuduhnya.
