Authors: Kurniawan Rahmat
Published: February 2023

PT. Titis Sampurna LPG Plant Limau Timur mengolah gas alam menjadi Liquefied Petroleum Gas (LPG) sebagai produk utama dan condensate sebagai produk samping serta lean gas sebagai bahan baku pembuatan Pupuk Sriwijaya (PUSRI). Dalam proses pengolahan gas alam salah satu peralatan utama yang digunakan adalah Reboiler Deethanizer E-403. Tipe Reboiler Deethanizer E403 ini merupakan shell and tube. Pada proses Liquefied Petroleum Gas (LPG), Gas to Gas Exchanger E-401 merupakan alat penukar panas yang berfungsi sebagai pemanas untuk kolom deethanizer. Oleh karena itu, kinerja Reboiler Deethanizer E-403 harus selalu diamati secara teratur dan kondisi operasinya dimaksimalkan sesuai dengan kondisi yang diinginkan. Berdasarkan hasil perhitungan nilaifaktor pengotor (fouling factor) yang didapatkan sebesar 0,00709 hr.ft².oF /Btu dimana nilai fouling factor tidak melebihi nilai fouling factor yang diperbolehkan yaitu 0,002 hr.ft².oF /Btu. Dari hasil perhitungan tersebut, kemampuan perpindahan panas pada Reboiler Deethanizer E-403 diprediksi akan berada di bawah kapasitas tugas panasnya pada bulan ke 72 dari sekarang. Oleh karena itu,pembersihan perlu dilakukan kembali selambat-lambatnya 72 bulan dari sekarang. Hal ini perlu dilakukan agar kinerja Reboiler Deethanizer E-403 dengan kemampuan perpindahan panas dapat melebihi tugas panas dan dapat kembali ke kondisi semula.

TUNING PID DENGAN METODE TYREUS-LUYBEN PADA LEVEL TRI ETHYLIN GLYCOL V 110 DI PT XYZ
Authors: Adika Fakhri , Waskito Wasis , Handaja Suka
Published: February 2023

Level Tri-Ethyline Glycol memiliki tinggi 12,192 m  dan berdiameter 0,762 m. Tri-Ethylin Glykol berfungsi untuk menyerap mengikat kadar uap air (H2O) yang ada pada gas alam. Di dalam Level Tri-Ethyline Glycol (TEG) terdapat senyawa kimia yakni Ethylin Glycol yang berguna untuk mengikat air yang berada dalam gas. Cara memisahkan air dengan gas yakni dengan menggunakan metode counter current pada Vessel. TEG yang mengikat/ menyerap uap air (H2O) dapat diregenerasi kembali dengan cara memanaskan pada suhu tertentu sehingga uap air (H2O) terlepas dari bahan kimia TEG lalu uap air akan berkumpul menjadi cairan (liquid) yang dialirkan menuju fasilitas skimmer untuk dipisahkan antara air dan minyak (kondensat gas alam). Kondensat ditampung ke dalam tangki kondensat sebagai produk sampingan. Air hasil pisahan selanjutnya disebut air limbah terproduksi akan di treatment oleh fasilitas Waste Water Treatment Plant (WWTP). Hasil dari proses WWTP diharapkan memenuhi baku mutu air limbah terproduksi, lalu dialirkan ke water pond untuk dipertahankan kualitasnya dan dimanfaatkan. Tri-Ethylin Glycol perlu dikendalikan dengan komponen-komponen sistem pengendalian. Transmitter LIT - 11001 berfungsi membaca nilai aktual TEG kemudian mengubah besaran proses menjadi beda tekanan yang akan diubah dalam bentuk sinyal electric 4-20 mA DC sebagai keluaran transmitter. Controller LC - 11001 memiliki mode kontrol Proportional Integral, mode Proportional digunakan sebagai penghilang error dan mode Integral berfungsi untuk menghilangkan osilasi yang dihasilkan oleh mode Proportional. I/P converter LY – 11001 berfungsi mengkonversi sinyal 4-20 mA DC menjadi sinyal 3-15 Psi agar dapat dibaca oleh actuator control valve. Control Valve LCV – 11001 menjadi komponen penggerak untuk mengatur banyaknya aliran yang harus keluar dari bottom process. Di pembahasan kali ini, kita akan memperbaiki tentang pengendalian PID pada level Tri-Ethylin Glycol dari yang semula kurang stabil menjadi pengendalian yang lebih stabil lagi dengan menggunakan tuning Tyreus-Luyben. Dan pada simulasi yang sudah saya lakukan, didapatkan hasil PID yakni Kp = 2018, I = 23,7 dan D = 1,7. Maka, bisa disimpulkan bahwa hasil tuning dengan menggunakan metode Tyreus-Luyben lebih baik dari pada kondisi aktual lapangannya.

Published: February 2023

Menganalisa penurunan laju produksi pada suatu sumur panas bumi sangat penting dilakukan demi memecahkan masalah dan keberlansungan hidup, apalagi pada sumur panas bumi tersebut tidak mempunyai sumur injeksi. Laju penurunan produksi suatu lapangan panas bumi dapat ditentukan setelah lapangan tersebut dioperasikan. Lapangan panas bumi Ulumbu adalah lapangan panas bumi vapour dominated yang telah beroperasi sejak tahun 2011-2022 dengan kapasitas sebesar 4 x 2.5 MW dari 1 sumur. Secara umum, penurunan produksi pada lapangan panas bumi adalah hal yang alamiah terjadi. Penurunan produksi ini dapat terjadi akibat faktor reservoir (reservoir problem), faktor lubang sumur (mechanical problems), atau pun faktor operasi. Semakin menurunnya produktivitas berakibat pada kemampuan pembangkit listrik. Pada lapangan panas bumi Ulumbu telah terjadi penurunan laju produksi dari tahun 2015-2020. Sehingga kemampuan pembangkit listrik menjadi menurun dan menyebabkan pengoperasian dari 4 x 2,5 MW menjadi 3 x 2,5 MW dengan penurun laju produksi sebesar 19,905 ton/hour, dan WHP sebesar 13,191 barg. Dan setelah dianalisa menggunakan data hasil pengukuran Multi Finger Caliper (MFC56C), pada pengukuran ini ditemukan permasalahan korosif dengan kadar 25% (cukup). Tidak ada permasalahan fatal pada sumur produksi yang berakibat pada penurunan laju produksi.

Published: February 2023

Objectives: To determine the frequency of rhabdomyolysis in children under treatment for Diabetic Ketoacidosis (DKA) at National Institute of Child Health (NICH). Materials and Methods: Total 100 patients who were suffering from DKA were enrolled. Blood and urine samples were collected from of each child in aseptic conditions in sterilized container and sent for base line labs, urine ketone and serum creatinine kinase (CK) levels. All the demographic details and duration of diabetes mellitus and DKA and its treatment were recorded on a predesigned data collection proforma. Results: Out of 100 patients, 43 were male and 57 were female with mean age of 9.79±3.26 years. Seventy percent of the patients were aged 7.1-14 years, followed by 25.0% patients were aged 1-7 years and only 5.0% patients were aged of 14.1-18 years. The Mean duration of DM and DKA were 3.89±2.75 years and 9.72±4.65 hours respectively. Mean RBS, Urea and Creatinine level were 404.9± 99.1, 35.70±27.5 mg/dl and 0.73±0.75 mg/dl respectively. Mean hemoglobin and WBC level were 13.61±14.3 g/l and 16.33±11.8 respectively. The mean Na level was 137.79±5.64 mmol/l, mean K level was 4.01±0.89 mmol/l, mean Phosphorus level was 27.6±42.0 mg/dl and mean Cl level was 106.8±6.3 mmol/l. The mean PH was found 7.1±6.49 and mean Bicarbonate was 7.56±3.01 mmol/l. Fifty two percent patients were treated for more than 24 hours and 48.0% patients were treated for less than 24 hours. 7% patients under treatment for DKA were suffered from Rhabdomyolysis and expiry was 5%. Practical implication: In this study we find out that there is very little chance of causing rhabdomyolysis under treatment for DKA but we should take precautionary measures to prevent its progression towards its complications i.e., renal failure and cardiac Arrest which can lead to mortality. This study will lead a positive role in early cure of the DKA patients to avoid further complication. Conclusion: It is concluded that in DKA patients Rhabdomyolysis is of clinical concern because it can result in significant morbidity and mortality by causing Acute Renal failure, DIC, Cardiac Arrest, Arrythmias, significant electrolyte imbalance, but there is very little chance of causing rhabdomyolysis under treatment for DKA in our setup and it too can be avoided by early and aggressive treatment of DKA.

Published: February 2023

Aim: To examine the associations between emotional intelligence (EI) and Binge Eating Disorder (BED) with a mediating role played by post-traumatic stress disorder (PTSD) in the unemployed population, thus performance in an integrated manner. Study design: A Cross-sectional study Place and duration of Study: Rural and urban areas of Punjab, Pakistan during the months of December 2020-2021 Methodology: For this purpose, Wong and Law Emotional Intelligence Scale, Binge Eating Scale and PTSD Check List–Civilian Version was used to measure EI, BED, and PTSD score, respectively. The assumptions were tested using non-linear regression-based partial least squares path modelling (PLS-SEM). Results: The results revealed that unemployed individuals are at enhanced risk to develop BED. High levels of EI help to cope the stress of unemployment and overcome BED and vice versa. In this study, PTSD, a cause of unemployment, was found to be negatively related to EI and positively related to BED. However, no mediation of PTSD between EI and BED was observed. Conclusions: Our findings suggest that enhanced emotional abilities are directly associated with lower levels of work-related stress and BED. However, a diagnostic study is needed to validate the findings and establish BED diagnosis in individuals with low EI. This study helps in validation of emotional intelligence as a factor in the development of binge eating disorder. It helps in the development of programs based on prevention of binge eating disorder in unemployed population on the basis of emotional intelligence level understanding. Keywords: Unemployment, eating behaviour, emotional stability, stress disorder, mediation analysis

El Plan de Recuperación, Transformación y Resiliencia y su impacto macroeconómico desde una perspectiva sectorial
Authors: Fernández Cerezo Alejandro , Moral-Benito Enrique , Quintana Javier
Published: February 2023

Motivación

El Plan de Recuperación, Transformación y Resiliencia (PRTR), vinculado al programa europeo Next Generation EU, detalla una agenda de inversiones que representan una oportunidad única para facilitar la transformación estructural de la economía española, tanto por su tamaño (unos 69.500 millones de euros o el 5,6 % del PIB de 2019) como por su énfasis en los retos de la digitalización y de la transición ecológica. Por este motivo, resulta de interés disponer de una asignación por ramas de actividad de dichas inversiones, al objeto de cuantificar su impacto macroeconómico teniendo en cuenta las interacciones entre los diferentes sectores de actividad.

Ideas principales

•De acuerdo con los resultados obtenidos, la plena ejecución de los fondos del PRTR tendría un impacto directo sobre el nivel del PIB de un 1,15 % en promedio anual y en un horizonte de cinco años, si bien podría elevarse hasta el 1,75 % al tener en cuenta los efectos de arrastre entre sectores.

•Los efectos estimados son heterogéneos entre ramas de actividad, cuyos sectores más beneficiados son los vinculados al proceso de digitalización (información y comunicación o servicios profesionales y técnicos), así como el sector de la construcción, debido a las inversiones en infraestructuras relacionadas con el proceso de transición ecológica.

•No obstante, la presencia de rigideces en el proceso de reasignación de recursos entre sectores de actividad podría limitar el efecto macroeconómico de las inversiones contempladas en el PRTR. Estos factores podrían reducir el impacto estimado desde el 1,75 % hasta el 1,3 % del PIB.
Instability Functional Training: Evidence-Based Recommendations for Coaches
Authors: Horn Jay
Published: February 2023

Instability Functional Training (IFT) has been a popular form of program design in personal training certifications, and thus, widely accepted among trainers and coaches when creating programs for their clients. Training philosophies around this exercise style have been plotted in various directions, ranging from mainstream advocacy to vehement opposition. It is common practice for personal trainers to utilize unstable training and blanket all clients into this methodology in specific and non-specific exercise programs. The research does support its viability in clinical rehabilitation settings; however, it may not benefit a healthier population and may even undermine their goals. We ask trainers and coaches to consider their current position on the validity of IFT and to examine the evidence when programming it for the general public whose primary goal is to improve how they look (e.g., lose fat mass and increase lean body mass). Therefore, this article aims to help identify the merit of instability functional training, objectively review the current literature and recommend a practical approach for trainers and coaches when designing general exercise programs for clients with aesthetic goals.

A Syntactical Analysis of Sentences Written by Deaf Students at the Senior High Level of a Public Special School in Sumbawa Regency
Authors: Haerani Aditiya , Jazadi Iwan
Published: February 2023

The purpose of this study was to determine the syntactic ability and the form of syntactic errors at the writing of deaf students at the senior high school level of Public Special School (SLBN) 1 Sumbawa. Participants in this study were five students consisting of 1 of the10th grade, 3 of the 11th students, and 1 of the 12th grade. The research was qualitative, while the data were collected using written tests. For the data analysis, the researchers used the theory of Chaer about syntactic functions and devices. The results of the study show that the forms of errors in the student's writing consist of errors on the use of subjects, predicates, objects, and adverbs. Other forms of errors lie in the order of words, word forms, and use of conjunction. Another finding is that some students were able to compile sentences based on S + Adv + P, while the other students were only able to compile sentences with the S + Adj pattern. Based on these findings, it is expected that parents or teachers play a role to teach children or students how to compose sentences with a simple pattern so that children who suffer from deafness are able to convey what they want to convey.

Published: February 2023

Background: Generalized pustular psoriasis (GPP) is a variant of psoriasis characterized by widespread erythematous skin studded with sterile pustules. In general, PPG is rare in children. Diagnosis is made from the clinical and histopathological examination. The rarity of GPP in children has resulted in a need for standardized guidelines. Case: A 4 year-old boy with a generalized pustular eruption and confluent scaly plaques on erythematous skin. Mild pruritus and general malaise were present. Histopathological examination confirmed diagnosis of GPP. Clinical improvement was achieved with a combination of topical corticosteroids, anti-histamine, and systemic corticosteroids for two weeks. Conclusion: A combination of topical corticosteroids, anti-histamine, and systemic corticosteroids can still achieve clinical improvement in children with GPP. Nevertheless, its adverse effects should always be considered, and strict monitoring is required.

 

Latar Belakang: Psoriasis pustulosa generalisata (PPG) merupakan salah satu varian klinis psoriasis yang ditandai oleh kulit eritema disertai erupsi pustul steril yang tersebar luas. Pada umumnya, PPG jarang pada anak-anak. Diagnosis berdasarkan pemeriksaan klinis dan histopatologis. Jarangnya kasus PPG pada anak-anak menyebabkan kurangnya pedoman tata laksana terstandarisasi. Kasus: Seorang anak laki-laki berusia 4 tahun dengan kelainan kulit berupa erupsi pustulosa generalisata beserta kumpulan plak berskuama pada dasar kulit eritema. Keluhan disertai gatal ringan serta rasa lemah dan lesu. Pemeriksaan histopatologis memperkuat diagnosis PPG. Perbaikan klinis tercapai dengan tata laksana kombinasi corticosteroid topikal, anti-histamin, dan corticosteroid sistemik selama 2 minggu. Simpulan: Kombinasi corticosteroid topikal, anti-histamin, dan corticosteroid sistemik mampu menghasilkan perbaikan klinis pada anak-anak dengan PPG. Meskipun demikian, efek sampingnya harus selalu diperhitungkan dan membutuhkan pengawasan ketat.
