Judul: Analisis Pemborosan Proses Produksi Roti ACS dengan Metode Value Stream Mapping di PT X.
Abstrak: Meningkatnya permintaan roti ACS di PT X membuat kapasitas produksi PT X harus ditingkatkan agar dapat memenuhi kenaikan permintaan tersebut. Adanya kenaikan permintaan membuat pekerja harus melakukan lembur untuk memenuhi permintaan. Seringnya pekerja melakukan lembur dikarenakan adanya kegiatan tidak bernilai tambah dan pemborosan yang terjadi di setiap stasiun kerja. Eliminasi pemborosan yang ada di lantai produksi adalah cara agar dapat memenuhi kenaikan permintaan tersebut. Tujuan penelitian ini adalah menganalisis proses dan pemborosan dengan VSM, mengidentifikasi pemborosan pada proses produksi roti ACS, dan memberi rekomendasi sebagai upaya perbaikan. Value stream mapping (VSM) merupakan salah satu lean tools yang memetakan aliran material dan informasi lewat current state map untuk mengidentifikasi pemborosan. Pemborosan yang diidentifikasi pada produksi roti ACS adalah inventori, menunggu, produk cacat, gerakan, dan proses yang berlebihan. Total waktu siklus adalah 12139.99 detik dari total lead time 16084.40 detik. Usulan perbaikan dilakukan dengan menggunakan metode 5W1H dan waktu baku. Perhitungan waktu baku mempertimbangkan penyesuaian menggunakan metode objektif dan kelonggaran. Alternatif solusi ini dapat mengurangi total lead time sebesar 28.77% menjadi 11456.48 detik dan waktu siklus 11338.86 detik.

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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
