Published: July 2020

Selama ini penelitian hanya fokus pada cara dan pemakaian alat proteksi untuk pasien dan pekerja radiasi. Bahan proteksi paparan radiasi ionik lain yang penting bagi pasien, pekerja radiasi, bahkan masyarakat umum adalah dinding ruangan radiologi. Dinding ruangan radiologi mempunyai syarat tertentu, seperti ketebalan, komposisi bahan, dan warna. Dinding harus berwarna putih agar bersih dari kotoran maupun mikroorganisme. Dinding ruangan tidak terkena paparan langsung, melainkan melalui hamburan, sehingga dosis paparan rendah. Dengan memvariasikan tegangan tabung sinar X seperti yang digunakan pada diagnostik, dilakukan pengamatan terhadap perubahan komposisi cat dinding dengan X-Ray Flourosence (XRF). Hasil penelitian menunjukkan perubahan besar pada laju dosis 1,19 mGy/s atau pada tegangan tabung 80 kV. Senyawa yang terkandung dalam cat menurun persentasenya, bahkan senyawa K2O dan Nb2O5 tidak terdeteksi. Hal ini menunjukkan bahwa jumlah pemakaian sinar X konvensional yang tinggi akan meningkatkan kerusakan cat dinding ruang radiologi.

Published: July 2020

This paper discusses a dynamics of interpretation that occurred in Indonesia, which is specifically limited or focused on the era of pre-colonialism to the era of colonialism. The limitation in this paper needs to be done considering the scope of study of interpretation dynamics in Indonesia is too broad. So with the addition of keywords the era of pre-colonialism and the era of colonialism is intended to limit the scope of the study of the dynamics of interpretation in Indonesia. This article uses a historical approach, which explains how the development and dynamics of Indonesian interpretation with the historical approach that occurred in the era of pre-colonialism to the era of Colonialism. As is well known, that the dynamics of interpretation in Indonesia emerged or began since Islam entered Indonesia. Then the dynamics continue to develop in such a way along with social, cultural, political developments, which occur in each era. From various commentary books that appeared in the era of pre-colonialism to the era of colonialism, it shows that the dynamics of the interpretation of the Qur'an in Indonesia can be said to be quite dynamic. This is due to the influence of dynamic localist politics, social and cultural conditions in each era and its regions.
Pada tulisan ini, dibahas sebuah dinamika tafsir yang terjadi di Indonesia, yang secara khusus dibatasi atau difokuskan pada era pra-kolonialisme hingga era kolonialisme. Pembatasan dalam tulisan ini perlu dilakukan mengingat cakupan kajian dinamika tafsir di Indonesia terlampau luas. Sehingga dengan penambahan kata kunci era pra-kolonialisme dan era kolonialisme ini dimaksudkan untuk membatasi ruang lingkup kajian dinamika tafsir di Indonesia. Artikel ini menggunakan pendekatan sejarah, yakni menjelaskan bagaimana perkembangan dan dinamika tafsir Indonesia dengan pendekatan sejarah yang terjadi pada era pra-kolonialisme hingga era Kolonialisme. Sebagaimana yang sudah maklum diketahui, bahwasanya dinamika tafsir di Indonesia muncul atau dimulai sejak agama Islam masuk di Indonesia. Kemudian dinamika tersebut terus berkembang sedemikian rupa seiring dengan perkembangan sosial, budaya, politik, yang terjadi disetiap zamannya. Dari berbagai kitab tafsir yang muncul di era pra-kolonialisme hingga era kolonialisme ini menunjukkan bahwa dinamika tafsir Al-Qur’an di Indonesia dapat dikatakan cukup dinamis. Hal tersebut disebabkan adanya keterpengaruhan dari keadaan sosial, budaya, dan politik yang dinamis-lokalis disetiap zaman dan wilayah-regionalnya.

O estudo das propriedades físico-químicas dos fluidos de perfuração é de grande importância para a indústria petrolífera. Nesse contexto, o presente trabalho teve por intuito sintetizar três fluidos de perfuração com diferentes composições químicas (Fluidos 1, 2 e 3), permitindo que algumas das suas propriedades fossem determinadas, tais como, densidade, parâmetros reológicos, filtrado e reboco, salinidade e pH. Após a realização das análises observou-se que o nitrato de bário não apresentou eficiência como adensante, pois sua adição afetou as interações entre as moléculas, gerando uma redução na viscosidade. Apesar do Fluido 2 apresentar algumas características interessantes para a indústria petrolífera a adição do adensante selecionado não foi adequada para o preparo desse fluido.

Abstract: The teaching medium is a knowledge of the teaching methods used by a teacher or instructor. Methods are the means used to achieve the established goals. Another technique is the presentation technique that is mastered by the teacher to teach or present the lesson materials to the students in the classroom, so that the lesson can be absorbed, understood and used by the students well. The better the teaching method, the more effective the achievement of the goal. Motivation is a change of energy within a person characterized by the emergence of "feeling and preceded by the response to the purpose, to get it then must be selected methods that if acceptable in teaching and learning activities well. In fact, the way or method of teaching used to convey different information in the way adopted to establish students in mastering knowledge, skills and attitudes (cognitive, psychomotoric, affective). Specific methods of teaching in the classroom, the effectiveness of a method is influenced by the purpose, student factors, situation factors, and teacher factor itself. Demonstration is a teaching method done by a teacher or someone else by showing the whole class about a process or a way of doing something. Demonstrations are always directed to the correct way of practice which is then Apliskasikan in everyday life. And recitation is also one of the learning media known as homework or students are given the task outside of lesson time. Both methods can be implemented simultaneously in the teaching and learning process.From the above statements can be concluded that in learning, students so as not to get bored then there should be variations in learning methods. Teachers must be clever in choosing a method, one of which is the Graphic method (concept map). In this case on the history of the use of Graphic method (concept map) is the right method to invite students to think and understand and apply in everyday life. Graphical Pendekata (konse map) invites us to make learning process more meaningful and conductive. Kewords: Grafis Media, Learning History, Student Chomprehensif

Published: July 2020

Introduction: The incidence of small and medium size renal stones is rising. Stone clearance, bleeding, urine leak and infectious complications are major concerns for urologist. Urologist chooses best technique from list of armamentarium available. Minimally invasive approach like Percutaneous Nephrolithotomy (PCNL) has significantly influenced the renal stone management since 1976. Miniaturisation of the instruments allow more effective and safer alternatives for urolithasis management.
Methods: This is a retrospective study in which the outcome of mini PCNL (mPCNL) was compared with standard PCNL (sPCNL) in management of nephrolithiasis.
Result: There were no significant difference in stone free rate between mPCNL and sPCNL (96.2 ± 3.6% vs 95.3 ± 4.8%). The total operative time was longer in mPCNL (55.2 ± 19.0 minute vs 62 ± 21.0 minute) but the difference was not statistically significant.
Conclusions: Mini PCNL is as effective as standard PCNL with fewer bleeding complications in management of medium sized nephrolithiasis.

Published: July 2020

Introduction: There are various international guidelines for the surgical treatment of upper ureteral calculi. For upper ureteral stone of less than 10 mm size, ESWL and URS are regarded as first line treatment. However, there is lack of national guidelines for appropriate surgical options for such stone in our settings.
Methods: The study was prospective comparative type involving 100 patients who were divided into ESWL and URS groups comprising 50 patients in each. ESWL and URS were performed after confirmation of stone size with ultrasonography and non-contrast enhanced computed tomography. All patients underwent X-ray KUB at one week and six weeks post procedure for confirmation of stone clearance. Those with residual calculi of size < 5 mm were considered stone free. Statistical analysis was done using Graph pad prism version 6.
Results: The mean age of patients in ESWL and URS groups were 41.28 ± 15.3 years and 42.84 ± 16.1 years respectively. The male to female ratio was higher in ESWL group. The mean size of the stone pre ESWL was 8.58 mm and pre URS was 8.44 mm. The percentage of stone clearance at one week and six weeks for ESWL was 56% and 90% respectively whereas for URS, it was more than 90% at both one week and six weeks. The complications were higher with URS (20%) than ESWL (8%).
Conclusions: The ESWL and URS are equally effective in stone clearance. The duration is longer with ESWL and the complications were more in URS group.

Published: July 2020

Introduction: Gram negative bacteria are commonly involved in wound infections and are significantly associated with morbidity and mortality because of increasing resistance to commonly used antibacterial agents. This study aims to evaluate the pattern of antibacterial sensitivity of the gram negative bacteria from wound swabs of accidental trauma cases.
Methods: This retrospective study was done by collecting all the culture positive reports for wound swabs of accidental wounds from the microbiology laboratory and analyzing the reports showing growth of gram negative bacteria for frequency of sensitivity to commonly used antibacterial agents.
Results: Culture positivity rate was 21.95% with growth of gram negative bacteria in 79.7% of cases. The most commonly isolated organism was Escherichia coli being 41.3% among gram negative isolates. Highly resistant bacteria were E. coli, Klebsiella pneumoniae and Acinetobacter spp.
Conclusions: As there is low culture positivity rate for wound swabs obtained before washing the wounds inflicted by accidental trauma, prolonged routine use of prophylactic antibiotic is not justified. Thoroughly washing the wound is very likely to decrease the rate of wound infection further and reduces the need of antibacterial agents. Culture and sensitivity test should guide the treatment when wound is infected because highly resistant gram negative organism may be involved in such cases.
