Judul: Pengoptimuman Penjadwalan Tenaga Sukarelawan di Daerah Bencana Menggunakan Fuzzy Goal Programming
Abstrak: Relawan seringkali dibutuhkan dalam menangani daerah bencana untuk melakukan beberapa tugas seperti pencarian dan evakuasi korban bencana, membagikan bantuan, dan menyediakan tempat yang aman untuk korban bencana. Namun seringkali adanya kesulitan dalam menjadwalkan tenaga sukarelawan sesuai keinginan dan keahliannya. Dalam karya ilmiah ini, dibuat model untuk penugasan sukarelawan yang memiliki dua tujuan, yaitu meminimumkan total biaya kekurangan yang disebabkan karena tuntutan tugas yang melebihi sukarelawan yang ada serta meminimumkan jumlah penugasan pada blok waktu dan tugas yang tidak diinginkan sukarelawan. Metode yang digunakan pada model ini adalah Fuzzy Goal Programming (FGP) dan diselesaikan menggunakan pendekatan operator-min Bellman dan Zadeh. Penyelesaian masalah ini dilakukan dengan bantuan software LINGO 19.0, yang menghasilkan nilai optimal berupa total biaya kekurangan minimum dan jumlah minimum penugasan pada blok waktu dan tugas yang tidak diinginkan sukarelawan. Hasil implementasi menunjukkan bahwa model dapat diimplementasikan pada kasus bencana di suatu daerah., Volunteers are often needed in dealing with disaster areas to carry out several tasks such as searching for and evacuating disaster victims, distributing aid, and providing safe places for disaster victims. However, there are often difficulties in scheduling volunteers according to their wishes and expertise. In this scientific paper, a model for the assignment of volunteers is created which has two objectives, namely minimizing the cost of shortages caused by task demands that exceed existing volunteers and minimizing the number of assignments in blocks of time and tasks that are unwanted by volunteers. The method used in this model is Fuzzy Goal Programming (FGP) and is solved using the Min operator approach Bellman and Zadeh. Solving this problem is done with the help of LINGO 19.0 software, which produces an optimal value in the form of the minimum total cost of shortages and the minimum number of assignments in time blocks and tasks that are unwanted by volunteers. The implementation results show that the model can be implemented in disaster cases in an area.

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.

Abstrak: This study aims to describe various morphometric parameters of male A. atlas moth, to found a correlation between the morphometric parameters and body weight on male moths, and to describe the reproductive system of male A. atlas moth. Male can distinguish from the female by comparing the antennae. The antennae of male is wider. There is a very strong correlation between the total body length and the body weight in linear equation Y = 0.875 X-1, 639 when Y is the weight in grams and X is the total body length in cm. Reproductive system of male A. atlas moth generally similer to B. mori reproductive system. Male A. atlas moth has reproductive system consists of a pair of testes, a pair of deferent duct with ampula ductus deferent, one spermatophore gland, one alba gland, one prostatica gland and one penis.
