Judul: Analysis and repair work system based on time and motion studies in production proccess of long stick biscuit
Abstrak: Every company want to increase their productivity. To achieve high productivity required special attention to effectiveness and efficiency of work accomplished. For that reason there is a need for analysis working movement and labor time required for one cycle of proccess. Time required to perform a proccess at the beginning and the end of a shift is different, related to decrement of labor’s motivation and stamina due to fatigue. Fatigue can be caused by working conditions, work capacity of workers, and others. Standard time is a “factor looseness and the adjustment factor is summed with the cycle time”. Standard time for the proccess of preparation of raw flour is 112.68 seconds, while the standard time for the packaging process is 90.74 seconds. Productivity can be calculated by dividing the output of that day with the number of workers and duration to accomplish one proccess, was obtained from the calculation of productivity of each workers in the process of preparation of wheat flour is 400 kilogram/hour, while the packaging productivity of each workers is 3.76 cartons/hour.

Judul: Analisis Keseimbangan Lini dalam Proses Produksi Roti Tawar di PT Nippon Indosari Corpindo – Cikarang
Abstrak: The high growth rate in particular industries based on agriculture is followed by the development of increasingly advanced technology, will lead into a global competition and the existing problems in industries become more complex. In facing these industrialized world problems and global competition, accurately efficiency, effectiveness, and productivity are the key factors to be able to compete competitively for each agro-based industry. One of the effort that can be done to support is with some planning and designing of appropriately production systems with a continue production line balancing that influenced by operator performance, properly layout, and also the production queuing. The purpose of this research was to determine the standard working time on a number of work components that be involved in the process of white bread production, to analyze the layout, and to analyze the performance of queuing system in white bread production line that already exist. Working time measurement used to determine the standard working time by using the Westinghouse method in determining the value of adjustments and looseness. The layout analysis was analyzed by determining the level of activity relationship, total closeness rating, and activity relationship chart. Queuing analysis was done by forming a model that consisted of two types, namely material flow balancing analysis and Monte Carlo queuing simulation technique. Monte Carlo simulation technique used to obtain entity in the form of customer analysis, server analysis, and queue analysis, which are customer analysis consisted of number of finished, average waiting time (Wq), and average cycle time (W); server analysis consisted of server utilization; and queue analysis consisted of average queue length (Lq), and average waiting time (Wq). Production process in PT Nippon Indosari Corpindo was done by involving the cooperation between machines and operators which was deterministic and probabilistic. Work measurement was useful in determining the standard working time, layout analysis and queuing analysis. Time measurement was done by using the stopwatch method to the operator to determine the standard time, where the standard time that obtained from the calculation is in the amount of 8.45 hours for 1 batch (443.5 kg) of bread dough production. White bread production line at the PT Nippon Indosari Corpindo had a product layout which adjusted by its production process with have a straight line shape workmanship. Based on the analysis using the Analysis Relationship Chart, the formation changing in Raw Material and Mixing Department was needed. Its changing be based on sequence of work flow; efficiency of distance, time, and work; temperature, noise; level of comfort; ease of surveillance; and the existing of communication / work control paper. The highest value of Total Closeness Rating was Packing department (176), followed by Crating (168), Mixing (165), Oven (164), Raw Materials (92) and Finish Good department (87). The changing were made in the context of efficiency of time, distance, and packaging material transferring cost from Raw Material department onto Packing department which have a far distant. Queue analysis carried out by forming a queuing models which were divided into 9 queue model, they were Model A with a material flow balancing analysis at

Judul: Hubungan Filogenetik Hylarana Mocquardii (Anura : Ranidae) Di Sulawesi Berdasarkan Pengukuran Morfologi Dan Molekuler Gen 12s Rrna Dan 16s Rrna.
Abstrak: Hylarana mocquardii merupakan spesies yang awalnya merupakan anggota spesies H.chalconota yang masih termasuk kompleks spesies karena terdapat banyak variasi dalam spesies ini. H.mocquardii pada akhirnya ditetapkan sebagai spesies yang hanya terdapat di Pulau Sulawesi. Pulau Sulawesi merupakan salah satu pulau di Indonesia yang memiliki sejarah geologi yang kompleks. Sejarah geologi yang kompleks dengan kombinasi reorganisasi habitat, aktivitas pegunungan yang aktif, dan adanya fluktuasi permukaan laut menjadi faktor pendukung terbentuknya fragmentasi habitat, migrasi, kolonisasi spesies, hingga terjadinya spesiasi. Konstruksi filogeni dihasilkan dengan membandingkan sekuen H.mocquardii dari kawasan Sulawesi yang mewakili semua bagian Sulawesi, yaitu Sulawesi Utara, Barat, Tengah, Tenggara, dan Selatan. Topologi filogeni juga terdiri atas sekuen H.chalconota, H.megalonesa, H.erythraea, H.signata, H.grandocula, H.similis, Sanguirana luzonensis, Limnonectes cf.kuhlii, dan Occydozyga baluensis yang diunduh dari genebank. Konstruksi filogeni dengan gen 12S rRNA dan 16S rRNA menghasilkan pola pengelompokan spesies H.mocquardii yang monofiletik dan membentuk empat kelompok, yaitu kelompok spesies di kawasan Sulawesi Utara, kelompok spesies di kawasan Sulawesi Tengah dan Sulawesi Barat, kelompok spesies di kawasan Sulawesi Tenggara, dan kelompok spesies di kawasan Sulawesi Selatan. Berdasarkan gen 12S rRNA diperoleh pengelompokan spesies H.mocquardii dengan dua subclade yaitu kelompok yang berasal dari kawasan Sulawesi Tengah dan Barat dan kelompok yang berasal dari kawasan Sulawesi Utara, Sulawesi Tenggara, dan Sulawesi Selatan. Berdasarkan gen 16S rRNA diperoleh pengelompokan spesies H.mocquardii juga menghasilkan dua subclade yaitu dengan kelompok spesies yang berasal dari kawasan Sulawesi Selatan memiliki pengelompokan sendiri. Hasil analisis molekuler ini kemudian dibandingkan dengan hasil analisis pengukuran morfologi. Dalam analisis morfometri ini dipisahkan antara analisis individu betina dengan jantan. Penelitian ini melakukan perbandingan antara hasil analisis morfometri dengan analisis molekuler. Pada hasil analisis morfometri pada individu betina setelah dilakukan uji lanjut tidak terdapat perbedaan dan pengelompokan. Pada hasil analisis morfometri individu jantan juga pada awalnya tidak terlihat adanya pengelompokan, tetapi setelah dilakukan uji lanjut Duncan terlihat adanya pengelompokan yang juga mendukung pada hasil analisis molekuler gen 16S rRNA yang menunjukkan bahwa kelompok spesies H.mocquardii di Sulawesi Selatan memiliki pengelompokan tersendiri. Berdasarkan penelitian ini juga diketahui bahwa proses invasi spesies H.mocquardii ke Pulau Sulawesi terjadi seiring dengan proses terbentuknya Pulau Sulawesi dan nenek moyang spesies ini berasal dari daratan Asia.
