Judul: An Implementation of Value Stream Mapping for Efficiency and Productivity Improvement at Gluten-Free Remix Flour Production
Abstrak: Proses produksi adalah kegiatan utama yang berorientasi nilai tambah untuk menjaga aliran efisiensi dan produktivitasnya dengan menghilangkan beberapa pemborosan di seluruh aliran proses. Value Stream Mapping (VSM) adalah upaya untuk mengurangi pemborosan dalam proses produksi dengan menerapkan konsep lean manufacturing, yaitu dengan mengidentifikasi dan menghilangkan segala jenis limbah. Implementasi value stream mapping sebagai rekomendasikan untuk perbaikan untuk mengeliminasi limbah yang telah teridentifikasi sepanjang aliran nilai dapat mengurangi lead time dari 16415 detik menjadi 12044 detik. Takt time proses produksi per unit produk menurun dari 256 detik menjadi 188 detik. Berdasarkan hasil tersebut, terjadi peningkatan efisiensi proses produksi, yang awalnya 64%, meningkat menjadi 88%. Selain itu, produktivitas produksi juga mengalami peningkatan dari 1,75 menjadi 2,39. Hasil tersebut menunjukkan eliminasi pemborosan yang terdapat dalam proses produksi dapat meningkatkan efisiensi dan produktivitas proses produksi.

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.
