Abstract

Pemanasan awal pada unit distilasi minyak mentah (CDU) berfungsi menaikkan temperatur minyak mentah sebelum masuk ruang pembakaran (furnace) untuk mengurangi beban kerja dari furnace. Pemanasan awal dilakukan dengan bantuan alat penukar panas 11-E-107. Tujuan penelitian ini adalah melakukan evaluasi alat penukar panas 11-E-107 berdasarkan parameter faktor pengotor (fouling factor, Rd), penurunan tekanan (pressure drop, ∆P), dan efisiensi. Evaluasi dilakukan melalui pengumpulan data aktual berupa laju alir dan suhu fluida panas (atmospheric residue) dan fluida dingin (desalted crude oil) selama bulan Juni 2023. Analisis hasil perhitungan dilakukan dengan membandingkan antara hasil perhitungan (Rd, ∆P, dan efisiensi) terhadap data desain. Hasil penelitian menunjukkan bahwa nilai Rd dari data aktual berkisar antara 0,0006 – 0,0014 hr.ft2.oF/Btu, lebih kecil dibandingkan data desain. Hasil analisis penurunan tekanan (∆P) pada shell dan tube berada pada rentang 0,1046 – 0,1305 dan 0,1031 – 0,1352 psi, lebih kecil dibandingkan allowable pressure drop. Efisiensi dari alat penukar panas 11-E-107 berada di antara 87,60 - 91,30%. Secara keseluruhan, kinerja alat penukar panas 11-E-107 dalam kondisi yang baik. Perawatan berkala perlu dilakukan jika efisiensi alat penukar panas berada pada nilai kurang dari 80%.

Abstract

Phlebitis is a nosocomial infection caused by microorganisms and is characterized by clinical symptoms experienced by patients for 3x24 hours during the treatment period in the hospital. Appropriate handling both pharmacological and non-pharmacological in phlebitis can help minimize pain and injury in children. Compress is an alternative non-pharmacological treatment that can be done using several types of compresses, namely warm compresses, 0.9% NaCl compresses and aloe vera gel compresses. This type of research is quantitative research with descriptive analytic research design. The sample used amounted to 15 respondents children who are treated in the aster room of Prof. Dr. Margono Soekarjo Purwokerto Hospital with incidental sampling technique. The main variable in this study is the degree of phlebitis. This research data analysis is carried out interactively, in which there are three components, namely data reduction, data display, and conclusion drawing. The degree of phlebitis in children decreased every day after giving warm compresses, 0.9% NaCl compresses and aloe vera gel compresses and did not cause side effects during the intervention process with an average decrease on days 2 and 3. The results of giving warm compresses to 5 respondents showed a decrease in the degree of phlebitis with an average value of degree of phlebitis 3 to degree of phlebitis 2. While giving 0.9% NaCl compress 1 respondent recovered from phlebitis with a degree score of 0 from the previous degree score of 2. For the administration of aloe vera gel compresses on 5 respondents showed a decrease with an average value of degree of phlebitis 2 to 0 and 4 of the total 5 respondents given the intervention showed a degree score of 0 or recovered from phlebitis. Giving compresses helps reduce the degree of phlebitis in children so that it can be used as an alternative intervention against the incidence of phlebitis in children.

Abstract

Effectiveness of Pre-Lecture Quiz to Improving the Creative Thinking. This research was aimed to describe the effectiveness of Pre-Lecture Quiz to improving student’s creativity thinking skill on Arrhenius acid-base topic. The research method used was quasi experimental with non-equivalen pretest-postest control group design. The sample selection was done by cluster random sampling, obtained XI IPA 3 as experimental class and XI IPA 6 as control class. The effectiveness of Pre-Lecture Quiz was showed by the significant difference for average n-Gain of flexible thinking skill between the experiment and control class, for experiment class was 0.70 with high categorize and for control class was 0.48 with middle cateogorize. The conclusion of this research is effective Pre-Lecture Quiz and has a high effect size to improving the ability of creative thinking on Arrhenius acid-base topic.Keywords: creative thinking, Pre-Lecture Quiz, Arrhenius acid-base DOI: http://dx.doi.org/10.23960/jpmipa/v19i1.pp37-49
