Abstract

Kantor PT Equity Life Indonesia merupakan perusahaan milik swasta yangbergerak dibidang asuransi. Kantor pusat PT Equity Life Indonesia berada di lantai 25Gedung Sahid Sudirman Center, di Pusat Kota Jakarta. Produk yang ditawarkan oleh PTEquity Life Indonesia adalah asuransi jiwa, asuransi kesehatan dan dana pensiun.Ditemukan permasalahan yang ada di Kantor PT Equity Life Indonesia yaitu pada fasilitas,organisasi ruang dan konsep ruang. Konsep ruang pada Kantor PT Equity Life Indonesiabelum memenuhi identitas kantor yang sesuai dengan visi, misi, dan nilai perusahaan.Organisasi ruang yang belum sesuai dengan job desk dan hubungan antar divisi,mengurangi efektivitas karyawan dalam bekerja. Hal itu berdampak pada berkurangnyaefektivitas dan fleksibilitas karyawan dalam bekerja. Tujuan dari perancangan ulanginterior Kantor PT Equity Life Indonesia ini untuk mewujudkan kantor dengan fleksibilitasyang dapat memudahkan karyawan dalam bekerja. Metode yang digunakan perancanganini adalah observasi, wawancara, kuesioner, dan studi literatur. Peracangan ini diharapkandapat memenuhi kenyamanan, produktivitas, dan fleksibilitas masyarakat dalam berkerjadengan mengoptimalkan organisasi ruang yang ada dalam perancangan.Kata kunci: Interior, Perancangan Ulang, Kantor Asuransi, Fleksibilitas

Abstract

This study explores strategies to enhance energy efficiency in maleic anhydride production through heat integration and feed preheating modifications within an existing process configuration. The process, based on benzene oxidation in a plug flow reactor followed by absorption and distillation, was modeled under steady state conditions to evaluate energy utilization across key unit operations. In the baseline setup, the reactor feed depended entirely on external heating, while significant thermal energy in the reactor effluent was lost through cooling utilities. To address this inefficiency, a modified configuration was introduced in which part of the effluent heat was redirected to the feed preheater, enabling internal energy recovery and reducing reliance on external utilities. Simulation results demonstrated a marked improvement in energy efficiency, with energy savings rising from 1.219×108 kJ/h (93.93%) to 1.625×108 kJ/h (96.04%) after modification. The redistribution of thermal load across the heat exchanger network confirmed that internal heat was effectively harnessed without incurring additional utility costs or capital investment. Overall, these findings highlight heat integration as a practical and economically advantageous approach to improving energy efficiency in maleic anhydride production while preserving operability and separation performance.
