Abstrak: The wool of local sheep is still a by-product that can be used for some craft products. The aims of this research were to study the wool weight yield during the processing and to know quality of the wool yarn. Parameters were consisted of wool weight yield percentage during sorting I, washing, sorting II, carding and during spinning, and the quality of yarn, i.e, strength and elongation of the yarn. This research used the T-test analysis. There were 5 repetitions for observed wool weight yield during the process; 2 repetitions for strength and elongation of the wool yarn from garut sheep; and 5 repetitions for strength and elongation of the wool yarn from batur sheep. The results showed that percentage of wool weight yield from garut and batur sheep was not significantly different, except for the yield in spin stage that tended to be different. The yarn quality was statistically similar between two types of wool, but for the elongation they tended to be different. Sheep breed difference was not significant on wool weight yield and yarn quality. It is concluded that wool of garut sheep can be processed to make yarn, as same as wool of batur sheep.

Abstrak: Batur sheep and garut sheep have good potential of their wool utilization because both types of sheep are crossbreed between local sheep with merino sheep. Research about wool quality of local sheep is still very limited. Information about growth rate and quality of wool would be useful as a reference for the utilization and processing of wool. Parameters observed in this research consist of growth rate, staple length, fibre diametre, staple strength, and staple elongation. Wool sample taken from midside body of sheep. This experiment was conducted on a sheep farm in Garut and Banjarnegara and Physical Evaluation Laboratory, Higher School of Textille Technology Bandung. Data were analyzed using T-Test method with 2 independent samples with five replicates of each samples and the data then was processed using Minitab 16. The analysis showed significant difference in the parameters of length, diameter and fibre growth rate. Conversely, breed factor had no significantly differences to staple strength and staple elongation. Batur sheep has a characteristic and wool’s quality better than garut sheep, so that batur sheep has a more chance to develop as a wools producer

Abstrak: At an emergency unit of a hospital are generally posted several physicians for 24 hours for each and every day. The management unit of an emergency room usually has to deal with schedulling problem of physicians with time constraint of availability. This scheduling problem can be modeled as an integer linear programming (ILP) problem. ILP is an optimization problem with linear objective function, linear constraints, and integer variables. Scheduling problem is formulated in an optimization model, where the objective function is to minimize the operational cost of emergency room with the following constraints: (i) the time availability of physicians, (ii) the balanced work load for every physicians, (iii) holiday and dayoff determination of each physician. This paper discusses the schedulling of an emergency room’s physicians problem in the form of ILP, with a case study at Emergency Unit of Cipto Mangunkusumo Hospital (RSCM), Jakarta. The model is solved using Lingo 8.0 software. The solution obtained using ILP scheduling method is found to be more balanced than the corresponding solution using conventional method.
