Universitas Terbuka (UT) was implementing the centralized distribution of learning material, it is not considered efficient. Therefore, the decentralized distribution system which requires warehouses at certain regional offices will be proposed. The aims of this research are (1) investigating the decentralized learning material distribution model, (2) choosing the optimal location of warehouses to minimize the cost of learning material distribution, (3) choosing the regional offices which will be served optimally by each warehouse, (4) comparing efficiency of the centralized and decentralized learning material distribution system. The distribution problem is modeled as a linear mixed integer programming problem. The model will be solved using Branch and Bound method. This study considers centralized learning material distribution system and two alternative of decentralized learning material distribution systems, which are alternative 1 and alternative 2. It is found that in 2008 the cost of the alternative 2 is lower than the centralized learning distribution system. Besides, if the demand of learning material is increasing, the alternative 2 is still less costly than the other systems.

One of problems that frequently occurs in hospital management is nurses scheduling problem. A suitable schedule is needed in order to avoid fatigue, both physically and psychologically, which subsequently may deteriorate their performance. Nurse scheduling is commonly designed by the head of nurse manually. In this research, nurse scheduling problem is modeled by considering the qualification of the nurses and the model has the form of integer linear programming. The objective of the model is to maximize the number of nurse’s day-offs. Then optimization problem is implemented to nurses scheduling in the High Care Unit and the Emergency room of Rumah Sehat Terpadu Dompet Dhuafa Parung Bogor.

Knowledge-based economics can[1] be achieved by using the role of knowledge to commercialize university research result in the agroindustry activities. Collaboration as a model to realize transfer of technology between university and agroindustry is institutional proven model. The use of science and technology in the new era of knowledge-based economy is expected to contribute in improvement of nation competitiveness. Decision making in the complex, dynamic and probabilistic problem as founded in the collaboration model needs analytical tools such as analytical hierarchy process (AHP), fuzzy inference system (FIS) and artificial neural network (ANN) as well as the combination of both techniques which is one of the best method for designing Model of University and Small, Medium Agroindustry collaboration in transferring technology as a reliable model in the future. Takagi-Sugeno-Kang Inference System is used to have input-output mapping using fuzzy logic, and artificial neural network with back propagation mechanism is used to get optimal membership parameters. Knowledge acquisition of the experts are needed together with ANFIS (adaptive network fuzzy inference system). After having simulation using Matlab program by combining ANFIS for Fuzzy membership function and certainty factor for non fuzzy membership function, recommendation is made on networking as collaboration pattern on transferring of innovation technology is the best choice, and fishery agroindustry using incubator technology as institution model is the best evidence of certainty factor achieved. Key words: collaboration model, technology transfer, AHP, neuro-fuzzy and takagi sugeno inference 6) Fakultas Matematika dan IPA, Universitas Indonesia

Disruption of the Java Sumatra Kalimantan (Jasuka) submarine cable communication system significantly impacted the smooth flow of communications. To reduce the impact, the detection of critical nodes in the network uses the critical node detection method to identify the most important nodes in the Jasuka network. This study aims to apply the critical node detection method as integer linear programming on the Jasuka network to obtain critical nodes by minimizing the number of paired connections on the nodes. The data in this research comes from the Jasuka network, represented as nodes and edges, and then analyzed using Python 3.11 software. The results showed that the critical node of the Jasuka submarine cable communication system is located at index 5 and 14 or the landing point Dumai, Riau and Palembang Jambi. The critical node on the Jasuka network can be a reference for Telkom Indonesia to pay special attention to the landing point because the damage will impact the entire network.

Optimal trainset dispatching can reduce passenger build-up and optimize operational costs. This research aimed to create a model of trainset dispatching for each time slot with minimum operational costs so that passenger demand can be met. The parameters in this research are the number of passengers getting-on and getting-off, the availability of each type of train series, train capacity, operational costs, and time limits for using the training series during operational hours. The model was formed into integer linear programming and resolved with Lingo 11.0 software. This model is applied in one direction from Bogor station to the Jakarta Kota commuter line. Trainset dispatching is done by selecting the 8 SF, 10 SF, and 12 SF trainset types with minimum operational costs at each time slot. The optimum results obtained during operational hours need to dispatch 56 trainset trips. Due to the limitations of the study the optimum operational cost of trainset dispatched is obtained 302C.
