ABSTRACTThe focus of this interenship report is to discuss about PT XYZ as a property company that claims reimbursement of its business unit, Hotel W. The claim relates to billing for providers of outsourcing services carried by third parties as service providers. The billing verification process is done from the time the bill was received by PT XYZ from third parties, then payment was made to third parties, and then claims the bill to the Hotel W, until PT XYZ received paymen from Hotel W. The verification process of billing documents currently carried out by PT XYZ is still using simple software. Therefor, it is proposed to use integrated software that will help the verification process to be carried optimally. In addition, the monitoring and evaluation system will also be carried out appropriately."

Tempat: Unit Terapi Intensif Rumah Sakit Jantung Harapan Kita Metodologi: Setelah mendapat persetujuan etik dari komite etik penelitian medis NCC, Harapan Kita Hospital, diperoleh 20 pasien laki-laki dengan BPK terencana. Volume cairan tubuh diukur dengan multiple frequency bioelecirical impedance (Dietosystem, Italy) pada frekuensi 1, 50, dan 100 kHz dengan menggunakan formula Guricci. Impedans diukur, 1 kali pra bedah dan 3 kali pasca bedah setiap 8 jam. Perubahan komposisi cairan tubuh dinilai dengan uji-t untuk 2 kelompok berpasangan. Nitrogen urea urin (NUU), kreatinin urin dan imbang nitrogen digunakan sebagai indikator katabolisme protein dengan menampung urin 8 jam pada interval yang sama dengan pe ukuran MFBIA Imbang nitrogen diperoleh dengan menghitung asupan dan NUU 24 jam pasta bedah. Hubungan antara perubahan cairan infra sel (CIS) dengan indikator katabolisme dihitung dengan uji korelasi Spearman Rank Hasil: Nilai ZI00 adalah 479 5l, indeks impedans 57,3 cm2/Q, dan volume cairan tubuh total (CM') 33,1 L terdiri dari 44,0% cairan ekstra sel (CES) dan 56,0% CIS. Pra bedah pasien termasuk euvolemia. Intra bedah terjadi imbang cairan +1744 (826-4312) mL. Delapan jam pertama terjadi peningkatan bermakna dari cairan tubuh. Dalam 24 jam pasca BPK+PJP terjadi peningkatan CTT 16,0%; CES 20,7%, dan CIS 13,0%. Peningkatan cairan masih dalam nilai euvolemia. Tidak terdapat hubungan bermakna antara perubahan volume cairan tubuh yang diukur dengan MFBIA dan imbang cairan. Median asupan selama 24 jam pasca bedah adalah 926 (127-1903) kkal dan 28 (0-69) g protein. Secara statistik terjadi peningkatan bermakna dari NUU pada 8 jam ketiga pasca BPK+PIP. Tidak terdapat perbedaan bermakna antara kreatinin urin pra bedah dan pasca bedah. Median imbang nitrogen -8{(-12,7) - (-1,6)} g. Terdapat korelasi negatif antara peningkatan volume CIS dan NUU (r - 0,57; p = 0,01). Kesimpulan Penelitian ini menunjukkan kompartemen cairan tubuh meningkat dalam 24 jam pasca BPK+PJP. Katabolisme protein ringan terjadi dalam 24 jam pasca BPK+PTP.

The Correlation Between Intra Cellular Water And Protein Catabolism After Coronary Artery Bypass Grafting: Using Multiple Frequency Bioelectrical Impedance Objective: (1) to investigate the changes of body water compartment within 24 hours after elective coronary artery bypass grafting (CABG) surgery with extracorporeal circulation; (2) to observe protein catabolism within 24 hours after elective CABG with extracorporeal circulation, and (3) to correlate between the changes of intra cellular water (ICW) with protein catabolism indicators. Location: Intensive Care Unit, Harapan Kita National Cardiac Center, Jakarta. Subjects and Methods: Twenty male patients with coronary artery disease were recruited for the study. Impedance was measured at 1, 50, 100 kHz using multiple frequency bioelectrical impedance (Dietosystem, Italy) four times: at baseline, at the 1°, 2 and 3 8 hours after surgery. The volume of body water compartment was calculated using Guricci's formula. Urinary urea nitrogen (UUN) and urinary creatinine were assessed using 8-hour urine collection within 24-hour period. Nitrogen balance was calculated by subtracting nitrogen intake with urinary nitrogen. The correlation between the changes of ICW and protein catabolism indicators was tested with Spearman Rank Correlation. Results: At the baseline, mean values of Ziw impedance and impedance index were 479 S~ and 57.3 cm21n, respectively. Mean total body water (TBW) was 33.1 ± 3.1 L or 48.8% of body weight, consist of 44.0% ECW and 56.0% ICW. This composition was classified as euvolemic. Median intra-operative fluid balance was 1744 (826-3412) mL. Significant increased in TBW, ECW, and ICW was observed at the 1' 8 hours. At the 3'a 8 hours after surgery, TRW, ECW, and ICW increased by 16.3%, 20.7%, and 12.8%, respectively, but the values were within desirable ranges. There was no correlation between TBW changes measured by MFBIA and calculated fluid balance. During 24 hours after surgery, median total energy intake was 926 (127-1903) kcal and protein intake was 28 (0-69) g. UUN increased significantly at the 3'd 8 hours after surgery. No significant difference in urinary creatinine was observed between before and after surgery. Nitrogen balance was -8 ((-12,7)-(-1.6)) g, and there was a negative correlation between ICW changes and NL-U (r = - 0.57; p = 0.01). Conclusions: The current study indicates that changes of body water compartment occur during 24 hours after CABG, ICW increases within 24 hours after CABG. Mild protein catabolism occurs within 24 hours after CABG. ICW changes have negative correlation with NULL However further comprehensive study is needed to explain this association, especially in CABG patients."

ABSTRACT

Young Adults have development tasks by having work and commitment in a relationship. The early adult phase is being experienced by new graduates of the bachelor degrees. To complete development tasks required self-efficacy. The existence of self-efficacy is one of the factors that influence coping mechanisms. This research was conducted on the relationship between the levels of self-efficacy with the two types of coping mechanisms in new graduates with single status. This study uses a cross-sectional design with sample of 107 people. The results of the analysis in this study here is a significant relationship between the level of self-efficacy and problem-focused coping (p-value = 0.002), and there is no significant relationship between the level of self-efficacy with emotion-focused coping (p-value = 0.266). The results of this study recommend that health workers carry out health promotion related to ways to improve self-efficacy and choices for using adaptive coping mechanisms."

"This paper describes how the reactivity of a cement when mixed with water can be detected qualitatively in the form of temperature rise through the measurement of its heat of hydration. The criterion adopted to assess the reactivity was the greater temperature rise, the more reactive the cement. It is directed towards assessment of three kinds of Indonesian cement, namely Portland, mixed, and pozzolan-lime. Found that POrtland cement is the most reactive, followed by mixed and pozzolan-lime.

"This book offers recommendations on the milling processes for the carbon fiber reinforced plastic CFRP/Al2024. Due to the anisotropic and non-homogeneous structure of CFRP and the ductile nature of aluminum, the machining of this material is very challenging and causes various types of damage, such as matrix cracking and thermal alterations, fiber pullout and fuzzing during drilling and trimming, which affect the quality of machined surface.The book studies and models the machined surface quality of CFRP/Al2024 using a two-level full factorial design experiment. It describes the processes of trimming using down milling, and statistically and graphically analyzes the influence and interaction of cutting parameters. Lastly, the book presents the optimization of the cutting parameters in order to create a surface texture quality of CFRP/Al2024 to less than 1 µm."
