Abstract

Introduction : Placenta accreta is defined as abnormal implantation of placenta villi which invades myometrium without the presence of decidua bacalis resulting in placenta that is difficult to remove. Based on the depth of invasion, placenta accreta is divided into three grades, placenta accreta, placenta increta, and placenta percreta. Placenta accreta developes if chorionic villi attaches to endometrium beyond desidua basalis. Placenta increta develops when chorionic villi invades the whole myometrium. Placenta percreta developes when chorionic villi attaches beyond myometrium reaching serous and abdominal organ. Based on clinical manifestation, placenta accreta is the common term being used. Incident of abnormal placenta invasion varies from 1 : 93.000 up to 1 : 540 pregnancy. PA incidence had increased four times from 1994 to 2002 in line with increased of caesarean section procedure. Other study showed history of caesarean section increased risk of placenta accreta up to 8,7 times. Placenta accreta index (PAI) was developed based on scoring process or various parameters assessment to help diagnose placenta accreta. The parameters including: history of caesarean section ≥ 2 times, lacunae grade, sagittal smallest myometrial thickness, anterior placenta previa and birding vessel. High PAI indicates high risk of abnormal placenta invasion based on histology.Objective : This study aims to investigate modified history of cesarean section score in placenta accreta index in predicting placenta accreta diagnosis in RSUP DR M  Djamil Padang.Material and methods : This was analytical study with cross sectional design. Study population was 84 placenta accreta patients in RSUP Dr. M. Djamil Padang from 2016 to 2019. Study sample was recruited using simple random sampling technique after meeting inclusion and exclusion criteria. Statistic analysis was done using Cohen’s Kappa test. Diagnostic test including sensiticivy, specivicity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy.Result : Strenght of agreement diagnosis placenta accreta based on PAI showed Kappa score of -0,002 (Kappa score < 0,2) which indicated  poor strength of agreement. Strenght of agreement diagnosis placenta accreta based on modified PAI showed Kappa score of 0,353 (Kappa score range from 0,21 to 0,40) which indicated fair strength of agreement. PAI diagnostic test yield sensitivity of 97,1%, specificity of 2,8%, positive predictive value of 48,5%, negative predictive value of 50%, and accuracy of 48,6%. Modified PAI diagnostic test yield sensitivity of 97,1%, specificity of 38,9%, positive predictive value of 60%, negative predictive value of 93,3%, and accuracy of 67,1%.Conclusion : PAI has high sensitivity, low specificity, moderate positive predictive value, moderate negative predictive value, and moderate accuration. Modified PAI has high sensitivity, moderate specificity, moderate positive predictive value, high negative predictive value, and high accuracy. PAI diagnosis has poor strength of agreement compared with pathology anatomy. Modified PAI diagnosis has fair strength of agreement compared with pathology anatomy. Modified PAI has identical sensitivity with standard PAI, meanwhile for specificity, positive predictive value, negative predictive value, and accuracy, modified PAI yields higher result compared to PAI.Keywords: Modified score of history caesarean section, placenta accreta index, Modified placenta accreta index, diagnostic test of placenta accreta diagnosis

Abstract

Artikel ini membahas analisis efisiensi eksergi water tube boiler pada unit penyediaan steam di plant pengolahan gas di Aceh, Indonesia. Tujuan penelitian adalah mengidentifikasi penggunaan energi aktual dan kerusakan eksergi akibat ireversibilitas. Boiler merupakan sumber utama kerusakan eksergi dalam sistem penyediaan uap, sehingga ada peluang besar untuk meningkatkan efisiensi kinerja dan mengurangi konsumsi bahan bakar. Hasil analisis menunjukkan efisiensi eksergi sekitar 65,9%. Total kerusakan eksergi mencapai 13,90 MW atau 62% dari eksergi masuk sebesar 22,40 MW, dengan kerusakan pada Combustor sebesar 37% dan Heat Exchanger sebesar 25%. Angka ini lebih rendah dibandingkan penelitian lain yang menunjukkan kerusakan eksergi hingga 89,13% dari eksergi masuk sebesar 279,58 MW. Kerusakan terbesar terjadi pada Combustor dan Heat Exchanger, dipicu oleh udara berlebih yang meningkatkan kehilangan gas buang, kerusakan isolasi termal yang menyebabkan kehilangan panas, pengaturan rasio pembakaran yang tidak seimbang sehingga terjadi pembakaran tidak sempurna, serta aktivitas blowdown yang hanya dilakukan saat konduktivitas tinggi, yang menurunkan efisiensi boiler.

Abstract

Edible film is a thin layer for primary packaging of food consisting of consumable components. In general, the purpose of this research is to examine the mechanical and physical properties of edible film in the influence of the addition of PVA and sorbitol as plasticizers and get the best edible film characteristics to be used as food packaging materials. The weight variations of porang flour used were 5 grams, 6 grams, 7 grams, 8 grams, and 9 grams. With sorbitol volume of 1 ml, 2 ml, and 3 ml, 4 ml, and 5 ml, and PVA mass of 3%, 4%, 5%, 6%, and 7% (b/v). The drying operation temperature was 40oC, 50oC, 60oC, 70oC, 80oC and the drying time was 12 hours and 24 hours. Then the thickness test, mechanical test, water resistance and solubility test, water vapor transmission test, and SEM (Scanning Electron Microscope) analysis were analysed. The best results are with variations of porang flour 6 grams, sorbitol 5 ml, PVA 5%, drying temperature 40℃, and drying time for 12 hours. The more sorbitol is added, the thickness, water resistance, water solubility, and elongation of the edible film will increase. The addition of konjac flour increases the thickness, water resistance, water solubility, tensile strength, and elongation of the edible film. However, it is inversely proportional to the water vapor transmission of edible film which has decreased.

Abstract

Overcoming climate change is crucial to ensure environmental sustainability. This research focuses on the development of chemically activated biochar (CAB) from mangrove litters that can be used for CO2 adsorption, which leads to reducing the impacts of climate change. The synthesisation of CAB was carried out via pyrolysis at 400℃ for 2 hours under nitrogen gas flow, followed by treatment using various activating agents (0.1 M of H2SO4, HCl, KOH, and NaOH) for 2 hours with a biochar-to-solution ratio of 1 g : 4 mL. The activation process was designed to enhance surface area, pore characteristics, and functional groups associated with CO2 adsorption performance. The observation on the characteristics of CAB using Scanning Electron Microscope and Energy Dispersive X-Ray (SEM-EDX), The Brunauer, Emmett, Teller and Barret-Joyner-Halenda (BET-BJH), Fourier Transform Infrared Spectroscopy (FTIR), CHN Analyser, and static batch CO2 adsorption tests shows the ability of CAB in capturing CO2 through several possible mechanism. Among the samples, KOH-activated biochar (B-KOH) exhibited the highest CO2 adsorption capacity, reaching 12.47 mmol CO2 g-1 biochar. This high performance is attributed to a potassium (K) composition of 9.74%, which effectively catalyzed the development of a microporous structure, resulting in a micropore volume of 5.927 x 10-3 cm3/g and an optimized average pore width of 1.543 nm. Furthermore, B-KOH maintained the highest O-H group area (1.533 a.u. x cm-1), enhancing its affinity for CO2 molecules. This research offers an innovative and practical solution to reduce greenhouse gases and is expected to have a significant impact, both locally and globally, in advancing sustainable development.

Abstract

Teknologi pinch adalah teknik berdasar ilmu termodinamika yang digunakan untuk mengoptimalkan konsumsi panas pada sistem proses industri menggunakan perancangan dan optimasi jaringan penukar panas (Heat Exchanger Network/HEN). One tool utama pada pendekatan teknologi penukar panas adalah curve komposit yang memaparkan hubungan antara entalpi dan suhu aliran panas (panas/steam) dan aliran dingin (cooling). Penelitian ini membahas penerapan yang dilakukan pada aliran proses sebanyak 11 aliran proses (4 aliran panas dan 7 aliran dingin) dengan variasi ΔTmin sebanyak 10°C, 12°C, 14°C, 20°C dan 22°C. Parameter yang digunakan berupa kepanasan panas (thermal capacity), perubahan entalpi dan entalpi kumulatif pada setiap interval panas. Hasil yang didapatkan menginformasikan bahwa perurungan ΔTmin akan meningkatkan efisiensi pemanfaatan panas berakibat pada biaya instalasi yang mahal. Sebaliknya, ΔTmin yang makin besar akan menurunkan efisiensi tetapi mengurangi kompleksi sistem. Dengan demikian perlu ditentukan ΔTmin yang tepat. Kata kunci: pinch technology, composite curve, ΔTmin, heat integration, energy efficiency, Heat Exchanger Network
