Published: July 2023

Jaringan sistem distribusi tenaga listrik merupakan media untuk mendistribusikan energi listrik baik ke industri, maupun pelanggan rumah tangga. Bertambahnya pertumbuhan penduduk maka pengguna atau pelanggan energi listrik juga bertambah sehingga dapat berdampak terhadap pembebanan pada setiap transformator distribusi. Kondisi jaringan distribusi yang tidak optimal akan mengakibatkan pelayanan yang kurang efektif, karena akibat terjadinya jatuh tegangan. Permasalahan yang dihadapi sekarang adalah ketika beban puncak tegangan yang sampai pada GH Tangse sebesar 17,9 kV dengan keadaan SG-11 yang menyuplai untuk 2 penyulang yaitu penyulang kota tangse dan penyulang geumpang dengan beban puncak 2,4 MW dan memiliki 70,72 kms dari GI Sigli. Penambahan Incoming SG-14 dan pengalihan beban pada Incoming SG-14 maka mampu mencukupi suplai beban yang ada pada 2 penyulang kota tangse dan penyulang geumpang, tegangan terima pada Gardu Hubung Tangse menjadi baik dan menaikkan tegangan dari 17,900 kV menjadi 19,760 kV pada SG-11 dengan melakukan perhitungan menggunakan software E-tap.

Authors: Muriyatmoko Dihin 
Published: July 2023

Hidroponik merupakan teknik bercocok tanam tanpa menggunakan tanah sebagai media tanamnya, sehingga pada hidroponik sangat membutuhkan air sebagai pengganti tanah untuk memenuhi nutrisi tanaman. Pengecekan nutrisi pada tanaman selada hidroponik sangat diperlukan, karena pertumbuhan bergantung pada nutrisi dan nilai pH yang ideal. Nilai pH yang ideal untuk tanaman selada adalah 6.00 – 7.00, sedangkan air pada hidroponik biasanya bersifat basa. Untuk mencapai nilai pH yang sesuai dengan tanaman, metode yang digunakan yaitu dengan melakukan pengecekan dengan pH meter lalu mencampurkan cairan asam atau basa hingga nilai pH sesuai dengan tanaman. Metode ini dianggap kurang efektif karena membutuhkan waktu yang lama dan keahlian khusus. Maka, dibutuhkan sistem otomatis yang membuat lebih efisien dan efektif. Tujuan dari penelitian ini adalah memudahkan bagi para petani hidroponik dalam pemantauan dan penetralisir nilai pH air pada tanaman selada secara otomatis. Alat utama yang digunakan pada penelitian ini yaitu sensor pH 4502C sebagai sensor pendeteksi nilai pH pada air, solenoid valve sebagai alat untuk menyalurkan cairan asam dan basa, relay sebagai pengatur arus masuk listrik dan ethernet shield sebagai media untuk menghubungkan arduino ke web server. Hasil dari penelitian ini berupa sebuah sistem kontrol pH tanaman selada dengan media hidroponik yang dapat memberikan informasi terhadap pengguna melalui lokal intranet berbasis website sehingga dapat memantau kondisi tanaman. Hasil dari pengujian yaitu nilai pH pada tanaman selada turun menjadi 5,67 dimana pH awal pada tanaman selada yaitu 8.00, hal ini menandakan bahwa sistem dapat berjalan dengan baik. Pengembangan kedepan diharapkan bisa diintegrasikan dengan aplikasi mobile.

Published: July 2023

The purpose of this study is to investigate the inclusion of social values in all reading texts of students' books in Action Pack Series One through Twelve. The study asked how much the Action Pack Series teaches social values like coexistence, cooperation, accepting differences, dialogue, love, peace, and human relationships. A quantitative and qualitative content analysis, with the paragraph as the unit of analysis, is used to answer this question. The results show that cooperation is the most common value in all twelve Action Pack series while accepting differences is the least common value in the same textbooks. The results show, without a doubt, that social values are common in grades 5–9. On the other hand, the next three classes put less emphasis on social values in the same readings. The researchers have come up with the following suggestions: Based on what the study found, it is suggested that the Ministry of Education offer seminars and training programs to help teachers better understand how texts show social values.

Published: July 2023

Background: Cardiogenic shock is the leading cause of death in patients with Acute ST-segment Elevation Myocardial Infarction (STEMI). Low free Tri-iodothyronine (FT3) levels are generally associated with poor prognosis in STEMI patients. This study was done to assess the association between FT3 levels and Cardiogenic shock in patients hospitalized with STEMI treated with streptokinase therapy.
Methods: This was an observational study of 140 patients of STEMI treated with streptokinase therapy in the department of cardiology, NICVD, Dhaka, Bangladesh from October 2018 to September 2019. The patients were divided into low FT3 (FT3 <3.5pmol/L; n = 70) and normal FT3 (FT3 e” 3.5pmol/L; n = 70) groups according to FT3 levels measured within 24 hours after admission.
Results: During the index hospitalization period, 30 patients developed cardiogenic shock, 23(32.9%) in low FT3 group and 7(10.0%) in normal FT3 group. There were 17 deaths with 18.6% in low FT3 group and 5.7% in normal FT3 group (p=0.01). MACE occurred 45.7% in low FT3 group and 18.6%in normal FT3 group (p=0.001). The mortality in patients with cardiogenic shock was 43.3% compared to 3.6% in patients without cardiogenic shock. Multivariate logistic regression analysis showed FT3 level was an important predictor for cardiogenic shock in patients hospitalized with STEMI (p=0.01).
Conclusion: Low FT3 levels were strongly associated with cardiogenic shock in patients with STEMI. The FT3 level screening may be a simple and valuable way to predict Cardiogenic shock after STEMI.

Background: Most countries in the world faced two waves of Corona virus disease-19 (COVID-19). But there is a lack of data regarding the wave-wise comparison of epidemiological and clinical characteristics of the COVID-19 outbreak. This study aimed to compare the demographics, clinical characteristics, and in-hospital outcomes of two waves of the COVID-19 pandemic in Bangladesh.
Methods: This prospective cross-sectional study was carried out at the National Heart Foundation Hospital & Research Institute. From April 3, 2020, to January 28, 2021, was considered the first wave, and from February 27, 2021, to September 25, 2021, was considered the second wave. COVID-positive patients and all admitted patients who became COVID-19 positive during these periods were included in this study for comparison.
Results: The first wave included 727 patients, and the second wave included 858 patients. The mean age of the patients in the first wave was 48.11 15.75 years, and in the second wave it was 50.65 16.63 years. Males were predominant in both waves. Healthcare personnel were less affected during the second wave (11.9% vs. 30.7%; p=0.001). Hypertension, chronic kidney disease, and cardiovascular disease were more prevalent in the second wave (p 0.05), and dyslipidemia and obesity in the first wave (p<0.05). During the second wave, 80.5% of patients were unvaccinated. Asymptomatic patients were predominant in the second wave (26.9% vs. 17.5%; p=0.001). COVID-19-related symptoms (fever, body ache, headache, anosmia, sore throat, shortness of breath, and diarrhea) were less prominent during the second wave (p<0.05). Oxygen requirements and IV antibiotic use were higher during the second wave (p<0.05). Asymptomatic & severe disease form were prevalent in second wave (p<0.05). Mortality rate was more during second wave (5.1% vs 3.4%; p=0.1). Age > 50 years, severe left ventricular dysfunction, severe and critically ill patients were the independent predictor of mortality.
Conclusion: In comparison to the first wave, during the second wave symptoms were less prominent, asymptomatic and severe disease forms were more prevalent & mortality rate was high. Unvaccinated persons are more prone to affected by COVID-19.

Authors: Shafi Masuma Jannat , Nasrin Sahela , Iqbal Md Jabed 
Published: July 2023

Background: This study was undertaken to evaluate clinical characteristics, indications, outcomes, and factors affecting outcomes in adult patients on mechanical ventilation admitted to CCU that will help planning of proper MV management programs. There are few studies in the coronary care unit (CCU) population and even fewer from developing countries.
Methods: All adult patients received MV at Ibrahim cardiac hospital CCU between June 2019 and July 2020 were prospectively recruited. Different demographic, indications, type and characteristics of ventilation, concomitant complications and treatment, outcomes, clinical and laboratory variables were recorded at the initiation of mechanical ventilation and daily, all throughout the course of MV & thereafter.
Results: Out of 1563 patients admitted to the CCU, 138 patients received IMV. Mean age was 64.2±12.1. Male were predominant (71.7% vs. 28.3%). DM was the most common (81.9%) risk factor. Reasons for intubation were as follows: type 1 respiratory failure (40%), type II respiratory failure (35%), and post cardiac arrest (25%). Mostly used mode of ventilation was A/C VCV (96.4%). Invasive MV was associated with high APACHE II score, low admission PH, Po2, and high Pco2. A higher in-coronary care unit death was observed in MV patients (65.2%) while that for MI (70.3%) than survivors (34.8%). CAG±PCI was (5.8%) keeping on MV or after extubation. The mean duration of MV, stay in CCU and hospital were (53.5±5.8, 80.5±7.6 and 128.8±12.0) hours respectively. The main factors independently associated with increased mortality were (i) pre-MV factors: age, APACHE II scores, acute left ventricular failure, and cardiogenic shock, sepsis (64.2±12.1, 39.1±19.2, 65.9%, 81.2%, and 70%). (ii) Patient management factors during ventilation: without positive end-expiratory pressure (65.6%) (iii) Factors occurring over the course of MV: PaO2/FiO2<100 (61.2±18.75) and development of renal failure (47.8%), VAP (40.6%), MODS (21.0%) & ARDS (8.7%) after initiation of MV.
Conclusion: Outcome among mechanically ventilated patients depended on the factors (including patient’s demographics, nature of associated morbidity, characteristics of MV received, and conditions developing over the course of MV). These factors may be present before or develop after initiation of MV as well as on the development of complications and the management protocols in the CCU.

Background & objective: Involvement of the right coronary artery frequently occurs in acute inferior myocardial infarction. Typical ECG changes in this condition involve ST-segment elevation in inferior leads. The present study was intended to predict the site of the lesion in the right coronary artery (RCA) in patients with acute inferior wall myocardial infarction using the height of ST-segment elevation as the predictor variable.
Methods: The present cross-sectional study was carried out in the Department of Cardiology, National Institute Cardiovascular Diseases (NICVD), Dhaka, Bangladesh over a period of one year between July 2010 to June 2011. Patients with acute inferior myocardial infarction admitted to CCU of NICVD within 12 hours of the onset of chest pain and underwent coronary angiography within 4 weeks of acute myocardial infarction (AMI) were the study population. With the help of a 12-lead ECG, magnitudes of ST-segment elevation in leads II, III, and aVF were measured. The highest degree of stenosis along the RCA revealed by an angiogram was accepted as the culprit lesion. The right coronary artery was divided into proximal (from its ostium to the origin of the RV branch), mid (from the RV branch to the acute marginal branch), and distal (from the acute marginal branch onward) parts. The sum of ST-segment elevation was then computed and compared among the three groups of patients divided on the basis of the site of lesion in RCA.
Result: The findings of the study showed that nearly half (48%) of the patients had lesions in the proximal, 38% in the mid, and the rest (14%) in the distal part of the right coronary artery (RCA). While patients with proximal lesions had the highest mean sum of the ST-segment elevation (12.1 ± 0.6 mm), those with distal lesions had the lowest mean sum of the ST-segment elevation (6.1 ± 0.2 mm). The three groups were significantly heterogeneous (p < 0.001). The magnitude of STsegment elevation in Lead II, III, and aVF and the sum of ST-segment elevation all were significantly higher in patients with proximal lesions than those in patients with mid and distal lesions (p < 0.001).
Conclusion: The magnitude of ST-segment elevation can predict the site of lesion in RCA in inferior wall myocardial infarction. The greater the height of STsegment elevation, the higher the probability of lying the lesion in the proximal part of the RCA.

Published: July 2023

Background: Young people who avoid strokes live longer and have more productive lives than their senior counterparts. The prevalence of the main vascular risk factors in atherosclerosis patients rises with age, starting in early middle age, and declines beyond 70–80 years. The majority of studies on young people are small and single-center, which makes generalization challenging. Stroke risk factors differ between men and women, and vascular risk factors are more prevalent in older age groups of young adult stroke patients.
Objective: The aim of the study is to find out the association of cardiac risk factors in young patients. Methods: This hospital-based cross-sectional study was carried out in the indoor patients in the Shaheed Suhrawardy Medical College Hospital, Dhaka, from April 2015 to October 2015. Young stroke patients (15-45 years old) admitted to the hospital were used as the study’s sample size.
Results: According to this study, the majority of patients (36.0%) were between the ages of 41 and 45. The percentages of patients in the 26–30–year–old, 31–35– year–old, and 36–40–year–old age groups were fairly close to one another (18.0%, 20.0%, and 22.0%, respectively). Just 4.0% of the population was under 25. The majority of the patients (64.0%) suffered from valvular heart disease. In addition, 10.0% had ischemic heart disorders, 16.0% had myocardial infarction, and 8.0% had atrial fibrillation. More over 75.0% of stroke patients also had some type of heart illness, according to the Framingham Heart study risk calculation.
Conclusion: Young adults from Bangladesh who suffered an ischemic stroke exhibited a high incidence of known cardiac risk factors, significant sex disparities, and alarmingly rising trends with age in both sexes. Regardless of where a person lives in the nation, preventive actions must be more aggressive and customized to each individual’s specific risk profile.
