Abstract

Recently, there are many hospitals as the health-care services choose to use the concept of Customer Relationship Management (CRM) to build the trust bridges between the hospitals and their patients. The implementation of CRM in health caring, especially for pregnant women needs to do; such as the delivery of information related to the pregnant women to get antenatal care as the scheduled or pregnant women desire to obtain information dealing with their pregnancy. The irrelevant, slow and inaccurate information can cause the health care services given to the patients are not optimal, so that they can reduce patients’ loyalty toward the health-care services. This research resulted health care information system based on Customer Relationship Management using Short Message Service (SMS) technology with case study of health care for pregnant women. The resulted information system is produced by the System Development Life Cycle methodology using the Waterfall model. One of the features produced is the pregnant women will receive a confirmation SMS to obtain antenatal care with a schedule until 28 weeks of their pregnancy check up every four weeks, 28-36 weeks of their pregnancy check up every two weeks, and 36-40 weeks of their pregnancy check up once a week.   Keywords: Pregnant Women, Antenatal Care, Customer Relationship Management, Short Message Service

Abstract

A company, majorly company that active in commercial (profit orientation) need to analyze their sales performance. By analyzing sales performance, company can increase their sales performance. One of method to analyze sales performance is by collecting historical data that relates to sales and then process that data so that produce information that show company sales performance.   A data warehouse is a set of data that has characteristic subject oriented, time variant, integrated, and nonvolatile that help company management in processing of decision making. Design of data warehouse is started from collecting data that relate to sales such as product, customer, sales area, sales transaction, etc. After collecting the data, next is data extraction and transformation. Data extraction is a process f or selecting data that will be loaded into data warehouse. Data transformation is making some change to the data afte r extracted to be more consistent. After transformation processing, data are loaded into data warehouse. Data in data warehouse is processed by OLAP (On Line Analytical Processing) to produce information.  Information that are produced from data processing  by OLAP are chart and query reporting. Chart reporting are sales chart based on cement type, sales chart based on sales area, sales chart based on plant, monthly and year ly sales chart, and chart based on customer feedback. Query reporting are sales based on cement type, sales area, plant and customer.Keywords: Data warehouse; OLAP; Sales performance analysis; Ready mix market

Abstract

Pada pembangkit listrik untuk mengalirkan uap dari Heat Recovery Steam Generator (HRSG) menuju turbin, maka diperlukan perpipaan sebagai media penyalur uap. Melihat pentingnya peranan pipa dalam operasi pembangkit maka diperlukan suatu analisis tegangan dalam perancangan yang mengacu pada code ASME B31.1. Kondisi uap yang dialirkan bertemperatur sebesar 535 0C pada kondisi operasi maksimum dan tekanan maksimum sebesar 47 bar menuju turbin uap high pressure. Analisis yang dilakukan menggunakan software analisa tegangan pipa berbasis metode elemen hingga dengan elemen garis yaitu pada beban sustain, ekspansi termal dan occasional (akibat pengaruh aliran uap terhadap belokan dan percabangan pipa). Dari hasil analisis yang dilakukan terdapat nilai tegangan pada beban sustain sebesar 24,482 MPa dengan rasio terhadap tegangan ijin 42,9%, pada beban ekspansi termal sebesar 95,301 MPa dengan rasio terhadap tegangan ijin 48,4%, dan beban occasional sebesar 24,590 MPa dengan rasio terhadap tegangan ijin 37,4%. Tegangan tertinggi terdapat pada percabangan tee 450 akibat tekanan internal dan kombinasi gaya serta momen dari sistem perpipan, namun tegangannya masih dalam batas di bawah tegangan ijin code. Untuk menurunkan tegangan pada tee 450 bisa dilakuan dengan metode reinforcement. Didapat hasil tegangan setelah dilakukan reinforcement yaitu pada beban sustain sebesar 21,002 MPa dengan rasio 36,8% dan beban occasional sebesar 21,101 MPa dengan rasio 32,1%. Selain itu dilakuan pula pengecekan menggunakan software lain dengan elemen volume yang didapatkan hasil tegangan equivalent sebesar 55,572 MPa dari beban sustain dan 56,1 MPa dari beban occasional. Disimpulkan bahwa tegangan yang terjadi masih berada di bawah tegangan ijin code, sehingga sistem perpipaan dapat dikatakan aman. Kemudian dilakukan simulasi dinamis dengan Eigensolver untuk mengetahui modus getar dan frekuensi pribadi sistem perpipaan. Didapatkan frekuensi sebesar 48,0815 Hz pada mode ke 13 yang mendekati frekuensi turbin 50 Hz. Tampak perilaku dinamis pipa di dekat turbin yang bergerak arah vertikal sumbu Y
