Judul: Studi Gerak Dan Waktu Serta Analisis Keseimbangan Lini Produksi Pada Proses Pembuatan Meja Setrika Di PT. Cosma Cipta Sejahtera Bogor
Abstrak: Time and Motion Study according to Barnes (1976) is the systematic study of work systems with the purposes of developing the preferred system and method usually the one with the lowest cost, standardizing this system and method, determining the time required by a qualified and properly trained person working at a normal pace to a specific task or operation, and assisting in training the worker in the preferred method. This activity had done from November 2010 until Februari 2011 at PT. Cosma Cipta Sejahtera, Cangkurawok Village, Dramaga, Bogor. Based on calculation, writers get the standard time is 4775.53 seconds or 79.59 minute or 1.33 hours. From this results, production target that can achieved by operators is 187 units/day. This results only different 7 units/day from production target that given by company, is 180 units/day. the total line efficiency score before repairing is 13.98% and after repairing with Helgson-Birnie methods is 82.01%. Line efficiency get increase after repairing with Helgson-Birnie methods. It looked at smoothness index and balance delay, that have decrease significantly from 7245.80 until 626.48, and for balance delay from 21.05% until 4.39%. This results showed that the writer’s idea condition have a better line balancing than first condition. Besides that, repairing of work condition are more important for operator to make them work comfortably, so it can minimize the late of achievement production target that can make an extra time for operator.

Judul: Analisis dan Perbaikan Sistem Kerja Berdasarkan Metode Studi Gerak dan Waktu Pada Lini Produksi Squash Orange di PT. Buanasari
Abstrak: Assessment of work productivity should be done routinely by a company. Achieving high productivity required special attention to efficiency and effectiveness of work. For that reason, there was a need to analyze working movement and work time required for one cycle of process. Time required at the beginning and the end of a process shift was different depends on the decrease of labor’s motivation and stamina, which related to fatique condition of labor. Fatique could be caused by working conditions and work capacity of workers. Motions were analyzed and grouped according to the cycle and type of motion. Average time of each motion adjusted with Westinghouse rating and allowances to obtain the standard time. Standard time for the squash orange production from was 25.46 seconds/bottle, while the standard time for the packaging process was 20.22 seconds/bottle. Productivity can be calculated by dividing the daily product output with the number of workers and duration to finish one cycle of process. It was obtained from the calculation that each production worker’s productivity was 36 bottles/hour, while the packaging worker’s productivity was 7 cartons/hour.

Judul: Penyebaran virus Newcastle-Disease (ND) pada burung liar
Abstrak: Banyak usaha yang telah dilakukan untuk mencegah dan mengendalikan terjadinya serangan wabah ND, seperti misalnya peningkatan sanitasi dan vaksinasi ND. Akan tetapi sam pai saat ini pengendaliannya belum dapat dilakukan secara tuntas. Banyak masalah yang menyebabkan kegagalan dari usaha untuk mengendalikan wabah ND, salah satu masalah yang perlu dipertimbangkan dalam penanggulangan wabah ND adalah sumber dan penyebaran virus ND oleh burung liar (Ronohardjo, 1980). Walaupun telah diketahui bahwa burung liar mempunyai peranan dalam penyebaran penyakit unggas, tetapi harus diakui bahwa sedikit sekali informasi mengenai jenis burung yang mempunyai potensi sebagai sumber dan penyebar virus ND. Selain menyebarkan penyakit unggas, burung liar juga dapat menyebarkan penyakit mammalia (Ottis and Bachmann, 1983). ...
