Riwayat Qalun dan Warsy pada Qiraat Nafi’ dalam Surah Al-Shaff
Authors: Suarni Suarni , Saiful Bahari Ahmad Sufian Bin
Published: May 2022

The riwayah of Qalun and Warsy is a way of reading the Qur’an that is widely circulated in Indonesian society with various differences. Unfortunately, people are not very familiar with the various ways of reading the Qur'an, even if they hear the reading of the Qur'an that is different from their habit, they will judge it as something foreign. From this phenomenon, it is necessary to explain to the public the procedures for reading the Qur'an from the riwayah of Qalun and Warsy, so that there will be no suspicion when they hear a different way of reading the Qur'an. The results show that there are many differences in the Qalun and Warsy qirãat contained in the ash-Shaff surah, there are 12 differences in terms of the manhaj qiraat. 4 differences in the (Ũshul) Qalun qiraat section and 10 differences in the Warsy qirat (Ushul) section. There are also 2 differences in the (Farsy al-huruf) section of the Qalun qiraat and there is 1 difference in the (Farsy al-huruf) section of the Warsy qiraat. The author also found 40 places in the whole of Surah al-Shaff which have different readings, for Qalun there are 24 different places and Warsy has 28 different places, so that the Qur'an cannot be read with only one version of qiraat. Riwayat Qalun dan Warsy merupakan cara baca al-Qur’an yang banyak beredar dalam masyarakat Indonesia dengan berbagai perbedaan yang ada. Sayangnya masyarakat tidak begitu familiar dengan beragam cara baca al-Qur’an, bahkan jika mereka mendengar bacaan al-Qur’an yang berbeda dari kebiasaan, akan menilai hal itu sebagai sesuatu yang asing. Dari fenomena ini perlu dijelaskan kepada masyarakat tata cara bacaan al-Qur’an riwayat Qalun dan Warsy, sehingga tidak akan muncul rasa curiga ketika mendengar car abaca al-Qur’an yang berbeda. Hasil penelitian menunjukkan bahwa banyak perbedaan qiraat Qalun dan Warsy yang terdapat dalam surah ash-Shaff, terdapat 12 perbedaan dari segi manhaj qiraat. 4 perbedaan pada bagian (Ushul) qirãat Qalun dan 10 perbedaan pada bagian (Ushul) qirãat Warsy. Terdapat juga 2 perbedaan pada bagian (Farsy al-huruf) qirãat Qalun dan ada 1 perbedaan pada bagian (Farsy al-huruf) qiraat Warsy. Penulis juga enemukan 40 tempat pada keseluruhan surah ash-Shaff yang berlaku perbedaan bacaan, bagi Qalun mempunyai 24 tempat perbedaan dan Warsy mempunyai 28 tempat perbedaan, sehingga al-Qur’an tidak dapat dibaca dengan satu versi qirãat saja.
Lafaz Sa’ala dalam Al-Qur’an
Authors: Nurullah Nurullah , Husna Siti
Published: May 2022

The Qur'an uses a lot of vocabularies that appear to be synonymous at birth, but when examined carefully it turns out that each vocabulary has its own connotation that does not exist in other pronunciations that are considered synonymous with it. As stated by Abi Isba' quoted by Nasiruddin Baidan that the beauty of the language of the Koran is classified into two major groups, namely the beauty of speech and the beauty of meaning. One of them is lafaz sa'ala, the lafaz is one of the lafaz that is repeated a lot in the Qur'an, 129 times, both in the same form and in different forms. This study is based on library research, besides that, the author examines these verses using the maudhu'i interpretation framework. Lafaz sa'ala is found in the Qur'an 129 times in 118 verses in 47 surah with 55 different forms of lafaz sa'ala. The whole lafaz sa'ala which means a question is repeated 73 times, whether there are two pronunciations in one verse or not. As for the meaning of asking to be called 49 times, while the meaning of asking is called 5 times and the meaning of rebuttal, speaking is only mentioned once. Alquran banyak memakai kosa kata yang pada lahirnya tampak bersinonim, namun bila diteliti secara cermat ternyata masing-masing kosa kata itu mempunyai konotasi sendiri-sendiri yang tidak ada pada lafal lain yang dianggap bersinonim dengannya. Sebagaimana pernyataan Abi Isba’ yang dikutip oleh Nasiruddin Baidan bahwa keindahan bahasa Alquran itu diklasifkasikan menjadi dua kelompok besar yaitu keindahan lafaz dan keindahan makna. Salah satunya adalah lafaz sa’ala, lafaz tersebut merupakan salah satu lafaz yang banyak diulang dalam Alquran, sebanyak 129 kali, baik dalam bentuk yang sama maupun dalam bentuk yang berbeda. Kajian ini berbasis kajian kepustakaan (library research), selain itu penulis mengkaji ayat-ayat tersebut dengan menggunakan kerangka kerja tafsir maudhu’i. Lafaz sa’ala ditemukan di dalam Alquran sebanyak 129  kali dalam 118 ayat di dalam 47 surah dengan 55 bentuk lafaz sa’ala yang berbeda-beda. Keseluruhan lafaz sa’ala yang bermakna tanya di ulang sebanyak 73 kali baik yang terdapat dua lafaz dalam satu ayat maupun tidak. Adapun yang makna nya minta di sebut sebanyak 49 kali, sedangkan yang bermakna memohon disebut sebanyak 5 kali dan yang bermakna bantahan, bercakap hanya disebut sekali saja.

Fernando Peixoto Traduz Turguêniev: noções fundamentais para uma estética marxista
Authors: Berton Paulo Ricardo
Published: May 2022

Em 1965, um ano após o golpe de estado que instaurou uma ditadura militar no Brasil, um dos grupos teatrais mais resistentes ao regime recém-estabelecido, o Oficina, resolve traduzir um autor dramático russo do século XIX que definitivamente não se enquadra na categoria de escritor revolucionário, mesmo tendo sido detido após o discurso proferido no funeral de Gógol em 1852, ter se posicionado contra a servidão e sofrido a censura czarista em algumas das suas obras. Ivan Turguêniev defendia reformas graduais em direção a um estado mais moderno, agnóstico, liberal e europeizado, o que angariou a inimizade de Tolstoi e Dostoievski, escritores contemporâneos a ele. No fundo, era um autor pessimista, cujas ideias apareceram de forma notória na sua novela Pais e Filhos (1862), através de uma personagem niilista, Bazarov. No Oficina, Fernando Peixoto (junto com José Celso Martinez), em meio a traduções de Maxim Gorki, este sim um símbolo da Revolução de Outubro, se debruça na de Um Mês no Campo (1855), acreditando, equivocadamente, estar se afastando de um teatro mais político. Este artigo visa refutar esta opinião de Peixoto, uma vez que o texto dramático de Turguêniev atende rigorosamente aos princípios estéticos defendidos pelos pensadores Karl Marx e Friedrich Engels.

The Effect of Proficiency on Non-Native English as a Foreign Language (EFL) Teachers’ Self-Efficacy and Practice in the EFL Classroom
Authors: Dewaele Jean-Marc , Leung Pearl P. Y.
Published: May 2022

The current study addresses the question whether the level of proficiency of teachers who teach a “non-native” language, English, affects their attitudes, motivation, well-being and self-reported classroom practices. This quantitative study is based on a cross-sectional research design in order to investigate the relationship between the actual English proficiency of 376 English as a Foreign Language (EFL) teachers from around the world who learned English as a foreign language and their sense of self-efficacy in the EFL classroom. Statistical analyses showed that more proficient teachers scored higher on the dimensions “Classroom practice” and “Attitudes toward students and institution”. They were also more motivated and happier. Intermediate (B1-B2) teachers scored significantly lower on these measures than EFL educators with Advanced proficiency (C1-C2). No significant differences emerged between teachers at Lower advanced (C1) and Upper advanced levels (C2). An argument is made that all dependent and independent variables are connected, highly dynamic and interacting directly and indirectly, which means that causality is multi-directional. The implication is that educational authorities should organise regular in-service training to maintain and boost teachers’ proficiency because investing in teachers’ linguistic skills represents a long-term investment in their emotional well-being and will ultimately benefit their students.

Published: May 2022

Background: Implanting leadless pacemakers in the right
ventricular (RV) apex is prone to causing pericardial tamponade and
myocardial perforation. Objective: To investigate the
feasibility and safety of right ventriculography-guided implantation of
Micra leadless pacemaker (Micra) in the RV
mid-septum. Methods: 108 consecutive patients who underwent
Micra implantation intended in the mid-septum were enrolled and
randomized (3:1) into the radiography group (n=81) with assistance of
right ventriculography to illustrate the RV septum and the
non-radiography group (n=27). All subjects underwent a postoperative
computed tomography (CT) scan to determine the Micra location. The Micra
location assessed by CT image was compared between the two groups to
confirm the accuracy of the intended pacing site. The duration of the
procedure, X-ray exposure dose and time were also compared between the
two groups. Results: Reconstructed CT 3-D cardiac imaging found
the Micra location in the intended mid-septum in 13 patients (48.1%,
13/27) in the non-radiography group and 76 patients (93.8%, 76/81) in
the radiography group ( P< 0.0001 between two groups).
There was no significant difference in procedure interval between the
two groups while the X-ray exposure (564.86±112.44 vs. 825.85±156.12mGy,
P < 0.0001), X-ray exposure time (7.79±1.43vs. 12.03±2.86 min,
P < 0.0001) and the number of fluoroscopy re-positioning
(2.79±1.03, vs. 6.41±1.82, P<0.0001) were significantly less
in the radiography group than in the non-radiography group. No
implantation-related complications were observed in both groups.
Conclusion Right ventriculography increases the accuracy of
Micra pacemaker implantation in the mid-septum and
reduces X-ray exposure.
Pulmonary vasodilator therapy in preterm children with bronchopulmonary dysplasia; a nationwide study
Authors: Jeremiasen Ida , Tran-Lundmark Karin , Dolk Mikaela , Naumburg Estelle
Published: May 2022

Objectives: This study aimed to map prescription patterns of
pulmonary vasodilator therapy in children with bronchopulmonary
dysplasia (BPD). Working hypothesis: Pulmonary vasodilator drug
therapy is used in children born preterm suffering from BPD-associated
pulmonary hypertension, but patient selection, extent of diagnostics
with catheterization and co-morbidities are largely unknown. Study
design: A descriptive national registry-based study. Patient
selection and methodology: All children below seven years of age who
had been prescribed a pulmonary vasodilator during a ten-year period,
2007-2017, born preterm (gestational age, GA <37 weeks) and
classified as BPD, were included. Information on prescriptions was
retrieved from the Swedish Prescribed Drug Register and information on
patient characteristics and comorbidities was retrieved by linkage to
national registers held by the National Board of Health and Welfare.
Results: In total, 74 children were included, 54 (73%) born at
GA 22-27 and 20 (27%) at GA 28-36. Single therapy was most common, N=64
(86.5%), and sildenafil was most frequently prescribed, N=69 (93%).
Bosentan, iloprost, macitentan and/or treprostinil were mainly used for
combination therapies, N=10 (13.5%). Patent ductus arteriosus (PDA) or
atrial septal defect (ASD) was present in N=29 (39%) and N=25 (34%)
children respectively, and N=20 (69%) versus N=3 (12%) underwent
closure. Cardiac catheterization was performed in N=19 (26%) patients.
Median duration of therapy was 4.4 (0.5-14.1, 95% percentiles) months.
Total mortality was N=7 (9%). Conclusions: Preterm children with
BPD are prescribed pulmonary vasodilators, often without prior
catheterization and sildenafil was most common. Diagnostic tools,
effects, and drug safety needs further evaluation.

Introduction. The inadvertent lead malposition in the left heart
chambers (ILMLH) is an under-recognized event which may complicate
implantation of cardiac electronic devices (CIEDs). Methods and Results.
We investigated the clinical conditions associated with ILMLH and the
treatment strategies in these patients. We made a systematic review of
literature and identified 132 studies which reported 157 patients with
ILMLH. Mean age of patients was 68 years and 83 were women. ILMLH was
diagnosed, on average, 365 days after CIEDs implantation. Coexisting
conditions were patent foramen ovale in 29% of patients, arterial
puncture in 24%, perforation of the interatrial septum in 20%, atrial
septal defect in 16% and perforation of the interventricular septum in
4%. At the time of diagnosis of ILMLH, 46% of patients were
asymptomatic, 31% had acute TIA or stroke and 15% had overt heart
failure. Overall, 14% of patients were receiving anticoagulants at the
time of diagnosis of ILMLH. After diagnosis of ILMLH, percutaneous or
surgical lead extraction was carried out in 93 patients (59%), whereas
43 (27%) received anticoagulation. During a mean 9-month follow-up
after diagnosis of ILMLH, 4 patients experienced TIA or stroke (3 on
oral anticoagulant therapy and 1 after percutaneous lead extraction).
Conclusion. ILMLH is a rare complication which is usually diagnosed
about one year after CIEDs implantation. An early diagnosis of ILMLH is
important. Lead extraction is a safe and effective alternative to
anticoagulants.
Measuring impact through health information system- a case study on maternal and perinatal death surveillance and response in Bangladesh
Authors: Sayem Abu Sadat , Kaasbøll Jens , Halim Abdul , Abdullah Abu Sayeed
Published: May 2022

Background: The health sector is one of the outstanding performers
through remarkable digitalization in health. Maternal and Perinatal
Death Surveillance and Response (MPDSR) was implemented in Bangladesh to
investigate the causes of maternal and perinatal deaths in community and
health facilities. Objectives: The purpose was to explore information
systems available to assess the MPDSR program status, the planning
process, gaps and barriers and actions developed using real-time
information. Data Collection and Analysis: This study included both
primary and secondary data analysis. Six key informant interviews and
MPDSR action plans were reviewed from seven districts. Secondary
collected from 27 districts. Results: This study revealed that the
government health information systems could notify 62% of the maternal
deaths and 29% of the neonatal deaths. Despite the challenges in data
quality, the health managers developed action plans. The death and
service data showed positive changes in most of the districts despite
COVID 19 pandemic. Information systems like the MPDSR dashboard and
RMNCAH scorecard could is used as tools to assess the impact of actions
in a real-time manner. Major gaps are weak monitoring, non-functional
MPDSR committees and incoordination, IT issues, blaming culture, and
lack of capacity in analyzing data. Conclusion: The outcome of the MPDSR
program depends upon how the data is converted to action and measuring
the impact. Innovative data visualization tools like health dashboards,
scorecards, and administrative data can play a pivotal role in measuring
and evidence-based planning. The major challenge remains with capturing
all deaths and weak data analysis capacity.
Temporal and biting dynamics of the malaria vectors Anopheles gambiae and Anopheles coluzzii harboring the 2La inversion in Bangui, Central African Republic

Published: May 2022

The chromosomal rearrangement 2La has been directly involved in the
ecological and deadly epidemiological success of the malaria mosquitoes
Anopheles gambiae and Anopheles coluzzii in sub-Saharan Africa. However,
little is known about the biological and ecological factors that drive
the local and temporal dynamics of this inversion in both species. Here,
we performed a year-round longitudinal survey in Bangui, Central African
Republic. We monthly sampled An. gambiae and An. coluzzii mosquitoes
indoor and outdoor using human landing catches for 48 hours non-stop. We
molecularly karyotyped all specimens to study the 2La inversion
frequency variations, and monitored the mosquito spatial and temporal
biting behavior throughout the year. In total, we successfully
karyotyped 5121 An. gambiae and 986 An. coluzzii specimens. The 2La
inversion frequency was higher in An. coluzzii than in An. gambiae
across the year. In An. gambiae and An. coluzzii, the inversion
frequency or karyotypes did not influence the biting behavior, either
location or time. Moreover, the inversion frequency variation in both
species was also independent of local climatic changes. Overall, our
results revealed that in Bangui, the 2La inversion segregates at
different frequency in each species, but this is not influenced by their
trophic behavior. Studying the impact of urban settings and the
population genetic structure of these two An. gambiae complex members
could bring insights into the intrinsic relationship between 2La
inversion and local conditions. More studies are needed to understand
the polymorphic equilibrium of this inversion in Bangui.
Patterns of stress response to foreign eggs by a rejecter host of an obligate avian brood parasite
Authors: Abolins-Abols Mikus , Peterson Mark , Studer Brett , Hale Mattison , Hanley Daniel , Bentley George , Hauber Mark
Published: May 2022

One of the most effective defenses of avian hosts against obligate brood
parasites is the ejection of parasitic eggs from the nests. Despite the
clear fitness benefits of this behavior, individuals within so-called
“egg rejecter” host species still show substantial variation in their
propensity to eliminate foreign eggs from the nest. We argue that this
variation can be further understood by studying the physiological
mechanisms of host responses to brood parasitic egg stimuli: independent
lines of research increasingly support the hypothesis that
stress-related physiological response to parasitic eggs may trigger egg
rejection. The “stress-mediated egg rejection” hypothesis requires
that hosts activate the stress-response when responding to parasitic
eggs. We tested this prediction by experimentally parasitizing
incubating American robins Turdus migratorius, an egg rejecter host to
obligate brood parasitic brown-headed cowbirds Molothrus ater, with
mimetic or non-mimetic model eggs. To assess the stress response, we
measured the heart rate in incubating females immediately after
experimental parasitism. We also measured plasma corticosterone and, in
a subset of birds, used RNA-sequencing to analyze the expression of
proopiomelanocortin (POMC), a precursor of adrenocorticotropic hormone
(ACTH), two hours after experimental parasitism. We found that egg type
had no effect on heart rate. Two hours following experimental
parasitism, plasma corticosterone did not differ between the differently
colored model egg treatments or between rejecter and accepter females
within the non-mimetic treatment. However, females exposed to
non-mimetic eggs showed an upregulation of POMC gene expression in the
pituitary compared to females treated with mimetic eggs. Our findings
suggest that parasitic eggs may activate the stress-related
hypothalamic-pituitary-adrenal axis in an egg-rejecter host species,
although the dynamics of this response are not yet understood.

Our research aims to identify approaches to promoting further education resources. Staff development is the main indicator of employee productivity and a productive "motivation factor" of increasing work initiative, strengthening the personnel behind the enterprise. Modern production places high demands on working personnel and the system of their training and retraining in the conditions of market relations. In the process of scientific and technological progress, some specialties disappear, others arise. All this creates a need for the latest forms of training, retraining and advanced training of employees. In this regard, educational institutions are faced with the need to find potential clients who need to meet the need for professional growth. Competition between organizations in the education market has intensified due to the pandemic. All this makes it relevant to use modern technologies in attracting the attention of employers to the opportunities for retraining and advanced training in a particular educational organization.
Vibration energy recovery system of vehicle suspension based on ultrasonic sensor
Authors: Wang Yunlong , Zhang Hongtian , Sun Yuantao
Published: May 2022

The current design of vibration energy recovery system for vehicle suspension
does not analyze the vibration of the vehicle under different road
conditions, resulting in the system's low energy recovery ratio, low
recovery efficiency, and low energy utilization. Therefore, in this paper,
the vibration energy recovery system of vehicle suspension based on
ultrasonic sensors is proposed. The ultrasonic sensor is used to obtain the
vibration information of the vehicle, and the vibration of the vehicle on
the smooth and uneven roads is analyzed according to the obtained
information. According to the analysis results, the design of the vibration
energy recovery system for vehicle suspension is completed through four
parts: the IGBT module, the control system, the direct thrust controller,
and the energy management controller. The experimental results show that the
system designed by the proposed method has a large energy recovery ratio,
high recovery efficiency and high energy utilization rate.
Thermal insulation performance analysis of high rise building envelope based on finite element analysis
Authors: Wang Quannan
Published: May 2022

The current analysis method of thermal insulation performance of building
envelope neglects the optimization of temperature control parameters, which
leads to poor thermal insulation performance, low thermal insulation rate
and weak convincing results. Therefore, a finite element analysis method
for the thermal insulation performance of high rise building envelope is
proposed. Compton backscattering technique is introduced to analyze the
influence of the scattering intensity and the ratio of window width on the
heat transfer coefficient of the enclosure. Based on the objective function,
the thermal performance parameters of retaining wall are calculated and
fused. An adaptive iterative optimization method is used to control the
thermal performance of the enclosure using the thermal performance
parameters of the enclosure. Through the Compton backscatter detection
technology, the decision variables of energy consumption of the thermal
insulation materials are obtained, and the temperature control parameters of
the walls are optimized. The finite element model of enclosure structure is
established by using finite element software. The results of finite element
model experiments show that the proposed method has ideal heat preservation
rate and energy consumption. Compared with the traditional method, the
proposed method can keep the preset temperature.
Design of burner performance optimization system based on laser machining
Authors: Guan Banggui , Qin Yanfu , Guo Minglei
Published: May 2022

The existing burner performance optimization system neglects the measurement
of single pulverized coal particle temperature in the combustion process, so
the temperature control error is large, which leads to poor performance
improvement of burner and poor control of residual oxygen. Therefore, a
burner performance optimization system based on laser machining is designed.
Design the overall frame of burner performance optimization. The performance
optimization of the burner is mainly realized by the control of temperature
and oxygen content. The gas quantity is calculated and fed back to the PID
controller through the error value and the rate of temperature difference
between the actual temperature and the set temperature. Based on the Hencken
plane flame burner, an optical measur?ing system for single pulverized coal
particle ignition based on laser processing is established to obtain the
temperature of the particles. Based on this, the Proteus-based burner
transient temperature distribution subsystem and the steady-state ANN
model-based temperature control optimization algorithm are designed. The
experimental results show that the burner of the system can control the
residual oxygen very well, and the temperature control result of the system
is highly fit with the simulation result, so the temperature control
precision of the system is high.
Diabetes Care Provider Perceptions Regarding Emerging Adults’ Diabetes Self-Management Influences and Patient-Provider Visit Interactions Within a Safety-Net Hospital
Authors: Wolf Rachel A. , Haw J. Sonya , Martyn Kristy K. , Kimble Laura P.
Published: May 2022

The increasing number of emerging adults with diabetes (EAWD) being cared for in adult health care settings requires a better understanding of the needs of EAWD and their interactions with adult health care providers (HCPs). This article describes findings from interviews with endocrinologists and diabetes nurses from a safety-net health care system to investigate HCPs’ perspectives regarding influences on EAWD self-management and HCP interactions with EAWD. HCPs frequently perceived lower EAWD engagement in diabetes management, which was complicated by barriers such as the emotional burden of diabetes, busy lives and multiple responsibilities, and limited access to resources; however, HCPs valued the role of information and communication at visits in tailoring care for EAWD. Measures to tailor care should address the psychosocial burden related to the life stage goals and priorities of EAWD, identification of resources for EAWD and HCPs, and further elucidation of effective self-management guidance and communication strategies to support EAWD in safety-net settings.

Benda uji sejumlah 16 buah dimana terbagi menjadi 2 kelompok yaitu benda uji yang diberi cor beton pengisi dan yang tidak diberi diberi cor beton pengisi. Setiap kelompok tersebut terdiri dari 4 buah benda uji kolom pendek dan 4 buah benda uji kolom panjang. Variasi perkuatan transversal pada masing-masing benda uji tersebut berbeda-beda yaitu 50 mm, 75 mm dan 100 mm. Data yang diperoleh berupa data lendutan kolom kesamping dan beban sentris yang dicapai oleh kolom. Penambahan cor beton meningkatkan kekuatan pada kolom pendek rata-rata sebesar 185,7%. Sedangkan pada kolom panjang rata-rata sebesar 148%. Defleksi maksimum terbesar kolom pendek tanpa cor beton pengisi sebesar 7,4 mm pada perkuatan 75 mm. Sedangkan pada kolom panjang tanpa cor beton pengisi sebesar 19,05 mm pada perkuatan 75 mm. Pada kolom pendek dengan cor beton pengisi defleksi maksimum tersebar terjadi pada perkuatan 50 mm sebesar 11,36 mm. Pada kolom panjang terjadi pada perkuatan 75 mm sebesar 27,1 mm. Pemberian cor beton pengisi terbukti dapat mencegah tekuk lokal yang terjadi karena dengan pemberian cor beton pengisi meningkatkan beban yang diterimanya hingga dapat melalui beban teoritisnya.

Peta gempa 2010 yang direncanakan untuk merevisi peta gempa sebelumnya, pada beberapa tempat mempunyai perbedaan nilai respon spektra desain. Tentunya untuk bangunan yang telah selesai direncanakan dan belum dilaksanakan di lapangan harus dilakukan analisis terhadap perilaku bangunan akibat perubahan beban gempa tersebut. Analisis ini bertujuan untuk mengetahui seberapa besar perbedaan perilaku jembatan bentang menerus akibat beban gempa rencana sesuai SNI-1726-2002 dengan beban gempa rencana sesuai peta gempa 2010. Pengaruh gempa dimasukkan dengan cara analisis dinamis menggunakan bantuan program SAP 2000 dalam model respon spektra. Beban gempa diaplikasikan pada model jembatan bentang menerus dengan jumlah bentang sebanyak 5 (lima) buah. Dari hasil analisis diperoleh perbedaan displacement dan daktilitas akibat beban gempa rencana sesuai SNI-1726-2002 dengan beban gempa rencana sesuai peta gempa 2010. Displacement yang terjadi akibat beban gempa rencana sesuai peta gempa 2010 lebih besar 30% dibandingkan besarnya displacement akibat beban gempa rencana SNI-1726- 2002. Hal ini dapat dimengerti mengingat bahwasannya besarnya nilai puncak respon spektra sesuai peta gempa 2010 lebih besar dibandingkan dengan respon spektra sesuai SNI-1726-2002.

Gaya memimpin para manajer proyek dalam membangun kepercayaan terhadap anggota timnya juga membawa dampak yang positif pads keberhasilan suatu proyek konstruksi. Tesis ini bertujuan untuk mengkaji bagaimana hubungan antara gaya kepemimpinan, kepercayaan dan keberhasilan proyek konstruksi dengan menggunakan uji regresi logistik (Logistic Regression). Uji regresi logistik ini dilakukan untuk mengetahui apakah terjadi hubungan antara gaya kepemimpinan, kepercayaan dan keberhasilan proyek konstruksi. Model regresi logistik merupakan model untuk menganalisis data yang berupa data kategorik nominal, dimana indikator satu nol diperhatikan sebagai variabel respon atau variabel tak bebas atau variabel dependen. Bentuk umum dari model regresi logistik adalah berdasarkan data bivariat (X, Y) dimana X adalah variabel numerik dan Y adalah variabel respon satu-nol. Berkaitan dengan uji regresi logistik tersebut, yang merupakan indikator satu nol dan variabel dependen adalah gaya kepemimpinan, sedangkan kepercayaan dan keberhasilan proyek konstruksi sebagai variabel independen. Sehingga dengan uji regresi logistik ini dapat diketahui apakah dengan kepercayaan anggota tim yang tinggi dan keberhasilan proyek konstruksi yang sukses memiliki gaya kepemimpinan transformasional atau gaya kepemimpinan transaksional. Hasil penelitian dengan menggunakan uji regresi logistik ini menunjukkan hasil bahwa hanya kepercayaan yang berpengaruh positif terhadap gaya kepemimpinan yang ada. Terlihat bahwa konstanta dan variabel kepercayaan adalah signifikan secara statistik sebesar 0,000 di bawah 0,05. Hasil ini ditunjukkan dengan persamaan regresi Y = -27,691 + 0,924X yang layak untuk digunakan. Dengan kepercayaan yang tinggi, gaya kepemimpinan yang dipakai oleh para manajer adalah gaya kepemimpinan yang transformasional.
ANALISA SENSITIVITAS PERTUMBUHAN LALU LINTAS DAN PROBABILITAS RISIKO PADA PEMBANGUNAN JALAN TOL KATEGORI PRIORITY PROJECT
Authors: Alfian Alfian

Pembangunan jalan tol di Indonesia dikembangkan melalui konsep kerjasama pemerintah dan swasta. Pengelolaan jalan tol oleh pihak swasta dibayang-bayangi oleh risiko dan ketidakpastian investasi. Pendapatan utama jalan tol berasal dari tarif tol yang dibayar oleh pengguna jalan tol. Oleh sebab itu, volume dan tingkat pertumbuhan lalu lintas selama masa konsesi merupakan unsur yang sangat berpengaruh terhadap tingkat pengembalian investasi. Rencana pembangunan ruas tol Pekanbaru–Kandis adalah salah satu ruas tol kategori priority project yang belum diminati oleh pihak swasta. Kajian ini dimaksudkan untuk mengetahui pengaruh volume dan tingkat pertumbuhan lalu lintas serta probabilitas risiko investasi, sehingga dapat digunakan sebagai salah satu pedoman dalam membuat keputusan investasi oleh calon investor dan kreditor. Jalan tol diasumsikan mulai beroperasi pada tahun 2016.Analisa dilakukan melalui simulasi dengan 10.000 iterasi pada tingkat pertumbuhan lalu lintas bervariasi antara 1% sampai 10%, tarif awal kendaraan Golongan I Rp. 490/km,dan masa konsesi selama 35 tahun. Hasil analisa melalui pendekatan stokastik memberikan informasi bahwa pembangunan ruas tol Pekanbaru – Kandis layak secara finansial pada tingkat pertumbuhan lalu lintas ≥ 10% dengan probabilitas risiko kerugian relatif rendah (percentile 1,71%). Kelayakan ini dipengaruhi oleh asumsi proyeksi volume lalu lintas di awal masa operasi yang cukup tinggi yaitu 15.274 kendaraan/hari. Jika investor membatasi probabilitas kerugian pada tingkat 5% (percentile 5%), maka investasi sangat berisiko bila pertumbuhan lalu lintas < 10% per tahun. Tingkat pertumbuhan lalu lintas kendaraan Golongan III, IV dan V merupakan faktor berisiko ranking ke-3 (di bawah SBI dan inflasi). Namun, tingkat pertumbuhan lalu lintas tidak memiliki pengaruh dan hubungan yang cukup signifikan terhadap Net Present Value.

Terdapat beberapa kondisi dan permasalahan pada teknik pantai yang tidak dapat diselesaikan dengan analisa matematika. Salah satu cara mengatasi permasalahan tersebut dengan penggunaan perumusan empiris. Model fisik merupakan metoda untuk memahami karakter hidrodinamis. Hubungan antara gelombang transmisi dan variabel pengujian dapat dimodelkan secara empiris. Untuk mewujudkan model tersebut diperlukan suatu alat (tool). Sesuai dengan karakter hubungan gelombang transmisi terhadap struktur pemecah gelombang kantong pasir, pada penelitian ini digunakan analisa regresi sebagai tool. Pada pemecah gelombang kantong pasir, nilai Dn50 relatif konstan, sehingga variabel tersebut tidak dapat dijadikan variabel pengujian. maka bentuk dan susunan kantong, lebar puncak, kemiringan susunan dan freeboard merupakan parameter yang dapat dijadikan sebagai variabel pengujian. Hasil uji statistik menunjukkan bahwa ç - 1÷ model  tak  linear  lnæ 1      öè Kt     ømerupakan model  yang cocok untuk  menggambarkan karaktergelombang transmisi pada pemecah gelombang kantong pasir tipe tenggelam.

Tanah lempung plastisitas tinggi diklasifikasikan sebagai tanah lunak dengan daya dukung dan kekuatan yang rendah. Stabilisasi tanah dibutuhkan untuk meningkatkan sifat tekniknya. Pencampuran tanah menggunakan semen telah dilakukan untuk menstabilisasi tanah ini. Pengaruh semen dan faktor air semen terhadap kuat tekan tanah dengan masa perawatan yang berbeda telah diinvestigasi. Uji kuat tekan bebas tanah (UCS) dilakukan pada tanah yang distabilisasi dengan kandungan semen 5%, 10%, dan 15% dari berat basah tanah dengan faktor air semen 20%, 25%, 30%, dan 35% dari berat semen. Masa perawatan sampel adalah 0, 3, 7, dan 14 hari. Tanah distabilisasi pada indeks likuidtias 0.50 dan 0.75. Hasil pengujian menunjukkan bahwa semakin tinggi proporsi semen yang digunakan, maka semakin besar peningkatan kuat tekan tanah, namun sebaliknya semakin tinggi faktor air semen yang digunakan, maka kuat tekan tanah semakin berkurang. Selain itu, tanan yang distabilisasi pada indeks likuiditas yang lebih rendah memberikan kuat tekan yang lebih tinggi. Kuat tekan tanah tertinggi dicapai pada campuran semen 15% dengan faktor air semen 20% yang distabilisasi pada indeks likuiditas 0.50, dimana kuat tekan tanah meningkat hingga 29.5 kali dari kuat tekan semula.

Authors: Sudarsana I Ketut
Published: May 2022

Perkuatan elemen struktur beton bertulang yang telah berdiri sering dilakukan dengan memperbesar dimensinya melalui penambahan ketebalan beton sebesar 50 sampai 80 mm. Perma-salahan yang sering dijumpai pada aplikasi metode ini adalah hasil pengecoran yang keropos se-hingga lekatannya kurang baik. Penelitian ini dilakukan untuk mengetahui kuat lekat dari beton ba-ru SCC pada permukaan beton lama. Sebanyak sembilan buah benda uji prisma ukuran 100x100x500mm dibuat dari dua jenis beton yang berbeda yaitu beton normal (f’c = 22 MPa) dan SCC (f’c = 26,4 MPa). Ada tiga variasi sudut interface (α) yang ditinjau yaitu 60o, 70o dan 75o dengan masing-masing variasi dibuat 3 buah benda uji. Sebelum dilakukan pengecoran beton SCC, permukaan miring beton lama terlebih dahulu dikasarkan sehingga membentuk alur-alur ver-tical, horizontal dan diagonal dengan kedalaman +/- 2,5 mm. Beban konsentrik tekan dikerjakan secara menerus dengan kecepatan standar test silinder beton sampai benda uji runtuh. Tegangan normal (σ) dan tegangan geser (τ) yang dihitung dari gaya aksial maksimum masing-masin benda uji dipakai untuk menentukan nilai kohesi (c) dan sudut geser () beton. Hasil pengujian menun-jukan bahwa nilai kohesi (c) beton SCC dan beton lama adalah sebesar 1.13 MPa dengan sudut ge-ser 53,2o.
