Abstract

The electroplating industry releases a high concentration of Chromium Hexavalent [Cr(VI)] up to 48.7 mg/L, significantly surpassing the quality standard of 0.1 mg/L. The activated carbon adsorption process is a cost-effective and straightforward approch to reducing the concentration of Cr(VI). Activated carbon can be produced from bagasse which is rich in cellulose. Due to limited information on the effect of carbonization temperature on the properties of activated carbon from bagasse, this study aims to identify the effect of carbonization temperature range from 450°C to 600°C and how it affects the performance of adsorbing Cr(VI). In addition, this study analyses the environmental impact of activated carbon production from bagasse with different temperature operating conditions through life cycle assessment. The research has four stages: carbonization, activation, adsorption, and environmental impact analysis. The result indicates that higher temperatures enhance the performance of activated carbon to adsorb Cr(VI) and produce the best-activated carbon quality. However, the environmental impact of performing at the highest temperature (600°C) is also the highest while having the lowest yield. Therefore, a temperature of 550°C is suggested to achieve fair product quality with good adsorbing performance, high yield, and less harming the environment. The hotspots of the production process lie in the freshwater aquatic ecotoxicity, acidification, and human toxicity due to using of H2SO4 and electricity.

Abstract

Paper ini membahas efektivitas dan improvement yang dilakukan pada proses bisnis pelatihan dan sertifikasi karyawan di PT. Motor Indonesia (PT MI). Efektivitas dirasa perlu dilakukan karena proses pelatihan dan sertifikasi seringkali tidak sesuai dengan kelas dan posisi karyawan dan kebutuhan organisasi. Selain itu proses paengajuan, persetujuan, pemetaan dan analisa pencapaian pelatihan dan sertifikasi memakan waktu lama. Untuk mewujudkan efektivitas tersebut, dibuatlah suatu aplikasi Certification Management System (CMS) dengan tujuan mengatasi masalah yang ada. Aplikasi CMS merupakan aplikasi berbasis web yang terintegrasi dengan Human Resources (HR) Portal. CMS dibangun menggunakan bahasa pemrograman ASP.NET dengan basis data SQL Server Management Studio 2012. Metodelogi yang digunakan adalah Metodologi Scrum. Dari pengujian dan implementasi aplikasi yang dilakukan, aplikasi CMS terbukti dapat mempermudah dalam pendataan dan pemetaan karyawan dengan kompetensi yang sesuai berdasarkan kelas, posisi, dan organisasi serta mempermudah karyawan dalam mengajukan sertifikasi untuk kompetensi yang dibutuhkan. Dalam hal reduksi sumberdaya, penggunaan CMS dapat mengurangi pemakaian kertas sebanyak 5.472 kertas A3 per tahun, mengurangi waktu penyetujuan sertifikasi dan pemetaan sertifikasi karyawan sebanyak 66% serta penurunan potensi kesalahan pemetaan karyawan dan sertifikasi sebanyak 70%.
