Judul: Identifikasi Waste Produksi Pulp Dan Penyebabnya Menggunakan Metode Lean Manufacturing
Abstrak: PT Toba Pulp Lestari, Tbk mengalami beberapa tantangan dalam proses produksi. Produk cacat menimbulkan masalah dalam penanganan persediaan berupa berkurangnya ruang penyimpanan. Sekitar 3 473.15 ton pulp cacat produksi menumpuk pada gudang hasil produksi menunggu untuk diolah kembali. Tujuan penetian ini adalah untuk mengidentifikasi da menganalisis penyebab pemborosan yang terjadi pada proses produksi. Alat peningkatan kualitas lean manufacturing seperti Value Stream Mapping (VSM), Process Activity Mapping (PAM) dan diagram fishbone digunakan untuk mencapai tujuan perusahaan. Peta aliran nilai menjelaskan kondisi saat ini, yaitu pemetaan aliran informasi dan materi dalam proses sebenarnya. PAM digunakan untuk menganalisis setiap aktivitas yang dilakukan pada aliran produksi dan mengetahui pemborosan yang terjadi. Penyebab pemborosan diketahui dengan menggunakan diagram fishbone. Hasil penelitian menunjukkan bahwa pada kondisi aktual, total waktu untuk seluruh proses yang diamati adalah 2 178.58 detik. Jenis pemborosan yang terjadi pada proses produksi berupa waktu menunggu menunggu, cacat produksi, dan terggangunya persediaan. Total waktu produksi setelah perbaikan pada peta masa depan untuk seluruh proses yang 1 894.97 atau berkurang sebesar 13.02%.

Judul: Perbaikan Aliran Proses Produksi dari Aspek Tata Cara Kerja dan Tata Letak Pabrik dengan Metode Value Stream Mapping (Studi Kasus PT. X)
Abstrak: Effectivity and efficiency of production flow can be achieved by eliminating identified waste in the flow process. Value stream mapping is a fundamental tool in lean manufacturing system to identify and eliminate waste. The objective of this research is to analyze the production flow in PT. X from the work procedure and factory layout aspect, so that the effectivity and efficiency of the flow process can be improved continuously. This research consists of several important steps; choosing a product to be observed, making the current state VSM for the chosen product, analyzing the current state VSM, and then making the future state VSM. The depiction of current state VSM shows that the production lead time for the observed product is 17 hours 53 minutes and 52 seconds, with the percentage of value added time counted 56,87%. The result of improvement analysis in this research shows a reduction of production lead time for 13,16%, and also an improvement of value added time percentage to 60,26%.

Judul: Query Expansion based on Bilingual Dictionary Using Conditional Probability
Abstrak: Query expansion is a technique that can be used to bridge vocabulary gaps between queries and documents in the collection. With query expansion, user will be helped to formulate queries well so that user will optimize the search result. In this study, the expansion term was resulted from the translation of bilingual dictionary. Subsequently, several terms of expansion were elected based on the closeness of its relationship with the original query. This research showed that conditional probability can be used to select expansion term in bilingual translation method query expansion. The result of 1000 documents was more than 97% relevan document can be retrieved by this system. The more expansion term used, the larger number relevan document was retrieved.
