KAJIAN EFISIENSI PERENCANAAN PC-I GIRDER DENGAN MENGGUNAKAN SISTEM STRAND 0,5” DAN 0,6” TERHADAP KEKUATAN DAN BIAYA
Authors: Richarlim Jessen , Leo Edison 
Published: February 2020

Prestressed concrete can be defined as concrete that given internal compressive stress such that it can reduce the tensile stress caused by external load to a certain condition. Stressing applied by pulling the tendon that has been installed on the concrete. 0,5” strand system are usually used for medium span. While 0,6” strand system is used for long span bridge. The purpose of this study was to determine the efficiency of PC-I girder using 0,5 "and 0,6" strands in terms of strength and cost. Strength analysis can be calculated by stress analysis, ultimate moment analysis and deflection analysis, while for cost analysis is a comparison of the cost composition between the 0,5 "and 0,6" strand system for each structural model reviewed. Structural modeling with hinge-roll at both ends and working loadings are dead load, additional dead load and live load. Loss of prestress force that is calculated depend on SNI 1725:2016 about loading for the bridge. The analysis shows that the use of the 0,5” strand has a better cost efficiency compared to the 0,6" strand. This can be seen from the design costs of the 0,5" strand system structure model is smaller than the 0,6" strand system structure model. AbstrakBeton prategang dapat didefinisikan sebagai beton yang diberikan tegangan tekan internal sedemikian rupa sehingga dapat mengurangi tegangan tarik yang terjadi akibat beban eksternal sampai suatu batas tertentu. Pemberian tegangan dilakukan dengan cara penarikan tendon yang telah diinstalasi pada beton. Sistem strand ukuran 0,5” biasanya digunakan untuk konstruksi jembatan bentang menengah. Sedangkan sistem strand ukuran 0,6” digunakan untuk konstruksi jembatan bentang panjang. Tujuan dari penelitian ini adalah untuk mengetahui efisiensi perencanaan PC-I girder dengan menggunakan strand 0,5” dan 0,6” dalam segi kekuatan dan biayanya. Analisis segi kekuatan berupa analisis tegangan, analisis momen ultimit dan analisis lendutan sedangkan untuk analisis segi biaya berupa perbandingan komposisi biaya yang dihasilkan dengan sistem strand 0,5” dan 0,6” untuk setiap model struktur yang ditinjau. Pemodelan struktur dengan perletakan sendi-rol pada kedua ujungnya dan pembebanan yang bekerja berupa beban mati, beban mati tambahan dan beban hidup. Kehilangan gaya prategang yang diperhitungkan sesuai dengan peraturan SNI 1725:2016 tentang Pembebanan Untuk Jembatan. Hasil analisis menunjukkan bahwa penggunaan strand 0,5” memiliki efisiensi biaya yang lebih baik dibandingkan dengan strand 0,6”. Hal ini dilihat dari biaya desain model struktur sistem strand 0,5” lebih kecil dibandingkan dengan model struktur sistem strand 0,6”.

Castellated beam actually was an original IWF beam which is cut by several pattern and welded properly in different part to provide higher profile. There are several factors that impact the strength of castellated beam such as, opening angle, cutting width, profile length, etc. This analysis aims to determine the relationship between profile lengths of castellated beam with the strength that the profile could bear until it fully failed, also observing buckling and failure behaviour on castellated beam using finite element method. This issue is necessary due to the characteristic of steel which easily get buckled. This analysis will be assisted by modelling the castellated beam profile using finite element based program. The profile size is IWF 200x100x5,5x8 which is formed into castellated beam size 300x100x5,5x8 with various lengths such as 4 m, 6 m, 8 m, 10 m, and 12 m. The load applied was concentrated load in the middle of the span, with fixed support on both edges of the beam. The results show that the shorter beam profile provides higher strength, and an extreme buckling phenomenon occurs to the longer beam profile, also the longer beam profile fails due to pre-yielding condition, therefore the failure is caused by geometric fails. AbstrakCastellated beam merupakan baja IWF biasa yang dipotong sedemikian rupa kemudian disambung kembali di bagian yang berbeda menggunakan las, sehingga dihasilkan tinggi profil lebih tinggi dari IWF orisinilnya tanpa harus menambah material. Terdapat banyak faktor yang memengaruhi kekuatan dari castellated beam, seperti sudut pemotongan, lebar pemotongan, panjang profil, dll. Analisis ini bertujuan untuk mengetahui hubungan antara panjang profil dengan kekuatan yang dapat diterima profil tersebut hingga runtuh serta melihat pola buckling dan kegagalan yang terjadi dengan metode elemen hingga. Hal ini merupakan sesuatu yang penting untuk diperhatikan berkaitan dengan sifat baja yang mudah mengalami tekuk atau buckling. Analisis akan dibantu menggunakan program berbasis elemen hingga. Profil yang digunakan yaitu balok IWF berukuran 200x100x5,5x8 yang dibentuk menjadi castellated beam berukuran 300x100x5,5x8 dengan variasi panjang profil 4 m, 6 m, 8 m, 10 m, dan 12 m. Beban merupakan beban terpusat di tengah bentang dengan perletakan pada kedua ujung batang berupa jepit. Hasil analisis menunjukkan bahwa baja dengan panjang profil lebih pendek menghasilkan kekuatan yang lebih tinggi, baja dengan panjang profil lebih panjang cenderung mengalami tekuk yang ekstrim, dan baja dengan profil lebih panjang gagal dalam kondisi baja belum mengalami kelelehan, sehingga kegagalan diakibatkan oleh kegagalan geometris.

Classrooms are room that must be given attention because it is used in the teaching and learning process. One that's annoying with the teaching and learning process is the increase in temperature in the classroom which allows less concentration on students and lecturers. To overcome these problems, the school usually equips the classroom with an air cooling system using either air conditioning or a fan. Most cooling systems that use fans are still operated conventionally using buttons on the fan or using remote control, this is considered to be less effective and efficient because we have to turn the fan on and off, adjust the fan speed manually. In fact, We often forget to turn off the fan even though it is already not needed, causing electricity to be wasted.
For this reason, we create a system that can turn on and off, adjust speed of fan rotation automatically based on certain room temperature thresholds, and create an Internet of Thing (IoT) based monitoring system to monitor room temperature and fan activity in the class. The system test results show that the entire fan control and monitoring system in the classroom has worked as expected.
Vesicle paleobarometry in the Pongola Supergroup: A cautionary note and guidelines for future studies

Abstract
Earth’s global barometric pressure, currently 1 bar at sea level, may have changed over its 4.5-billion-year history. Proxy measurements, including N2/36Ar ratios in ~3.5 to 3.0 Ga hydrothermal quartz, ~2.7 Ga raindrop imprints, and ~2.7 Ga vesicle sizes in subaerial basalt lava flows indicate Archean air pressure could have been between 0.1 and 1.2 bar. However, some models argue air pressure in the Archean should have been much higher than now and could allow pressure broadening of greenhouse gas absorption lines to counteract the “Faint Young Sun”. Thus, additional paleobarometric measurements would be useful to further constrain Earth’s atmospheric evolution. We attempted to use vesicle sizes in lavas erupted near sea-level from the ~2.9 Ga Pongola Supergroup from Mahlangatsha and Mooihoek, eSwatini (formerly Swaziland) and the White Mfolozi River gorge of KwaZulu-Natal, South Africa to provide further Archean paleobarometric data. However, reliable results were unobtainable due to small and scarce amygdales, irregular vesicle morphologies and metamorphic mineralogical homogenization preventing the use of X-ray Computed Tomography for accurate vesicle size determination. Researchers attempting paleobarometric analysis using lava vesicle sizes should henceforth avoid these areas of the Pongola Supergroup and instead look at other subaerially emplaced lava flows. With this being only the second time this method has been used on Precambrian rocks, we provide a list of guidelines informed by this study to aid future attempts at vesicular paleobarometry.

Background:Our hypothesis was that by identifying certain preoperative predictive factors, we could favorably impact clinical outcomes in patients undergoing decompressive surgery for lumbar spinal stenosis (LSS).Methods:In this retrospective study, there were 65 patients (2016–2018) with symptomatic LSS who underwent decompressive laminectomy without fusion. Their clinical outcomes were assessed utilizing the Oswestry Disability Index (ODI). Multiple preoperative variables were studied to determine which ones would help predict improved outcomes: gender, age, body mass index (BMI), general/neurological examination, smoking, and drug therapies (anxiolytics and/or antidepressants).Results:All patients demonstrated statistically significant improvement on the ODI. Multivariate analysis revealed that those with higher preoperative BMI had significantly lower ODI on 1-year follow-up examinations, reflecting poorer outcomes. Postoperatively, 44 patients (67%) exhibited lower utilization of anxiolytic medications, 52 patients (80%) showed reduced use of antidepressant drugs, and pain medications utilization was reduced in 33 patients (50%).Conclusion:Decompressive laminectomy without fusion effectively managed LSS. It reduced patients’ use of pain, anxiety, and antidepressant medications. In addition, we found that increased preoperative BMIs contributed to poorer postoperative outcomes (e.g., ODI values).
Malaria in Pregnancy in Nigeria: A Literature Review

Published: February 2020

Malaria is caused by the parasite plasmodium which can be spread to humans through the bite of an infected mosquito. Of the five types of plasmodium (P. Falciparium, P.Ovale, P. Malaria, P. Vivax and P. Knowlesi), the plasmodium falciparium is the deadliest and affects the lives of almost 40 per cent of the world’s population with pregnant women and children under-five years of age being the most affected. This mini-review involved the collation of findings from recent studies in regards to the prevalence of malaria infection among pregnant women and infants. A systematic analysis of recent literature on the prevalence of malaria in pregnancy from many authors was carried out and the facts synthesized to make an easy read. From the analysis of literature, Ten Thousand women and 200,000 babies were reported to be dying annually from complications of malaria in pregnancy which recorded a prevalence of 85 per cent in sub-Saharan Africa. More so, Fifty per cent of pregnant women were discovered to be carrying plasmodium falciparium in their placenta without even experiencing malaria signs/ symptoms, and this development was reported to have been responsible for Twenty per cent of stillbirths and 11 per cent of all maternal deaths. Malaria infection is considered a major threat to the lives and well-being of pregnant women and infants. Therefore, stakeholders should ensure that every clinical diagnosis of malaria in pregnancy is confirmed with a laboratory plasmodium falciparium-based diagnosis before the administration of antimalarial drugs. Furthermore there should be a stepping –up on the distribution of insecticide treated nets alongside enlightenment of pregnant women on ways of preventing mosquito bite. Instituting the aforementioned approaches is key to improving the health- seeking behaviour of pregnant women in particular and the wider population in general thus enabling them to stay malaria free throughout the period of pregnancy and infancy.
