This reserach proposes an integer linear programming model for the allocation of municipal solid waste to the optimal transfer station. This model involves trade-off between two kind of transportation cost, that is transportation cost from village to trasfer station and cost from transfer station to landfill/treatment center. Branch-and-bound method is used to find optimum decision, which transfer station should serve which village.This model is applied to city of Surakarta that consist of 596 village and 62 transfer stations. From analysis we know that this model can reduce total transportation cost per day by 5,38% and balances the accumulated waste in all trasfer station

To face globalization era that led to a more competitive, a higher education institution need to set up a strategic management system in order to develop its organization performance to survive and winning the competition. To set up strategic management, the institution must exactly recognize the performance level of it’s organization. That’s why the performance measurement system to help the organization enhance its performance is needed.XYZ college as a higher institution, wants to improve it’s performance by developing a management system to evaluate the current implemented strategy. The balanced scorecard approach as one of performance measurement method by integrating financial and non financial measures is used to design the the performance measurement system in this research. The balanced scorecard design of XYZ college constructed by considering the model from BAN, Competitive Funding Scheme, and the result from other researches. To accommodate the vision, mision, and objective of the XYZ institusion, this research involved thirthteen respondent who are executives management that consist of: Director; director assistant, and department chairmans. After the performance measurement system designed using balanced scorecard method, the weight of each perspectives, objective criterias, and performance indicators then calculated using AHP method. Next, performance level of institusion represented by 1-10 scale based on OMAX. This research present the XYZ College performance measurement result of 2004 and proposes strategic suggestion to enhance the institution performance.

Plasa Telkom Solo is a service place belonging to Telkom which is provided to serve Telkom customer with nine service servers. Those nine services servers can handle new setting and mutation, complains, information, and cash payment and non cash payment. Queue in the scale of customer service is important to be considered because the long queue will make the customer uncomfortable. The queue happens because the need of service is bigger than the capacity of service. Therefore, the customer cannot be served immediately because the busy service. This research is conducted to analyze the queue system to find the best number of the server and service system in Plasa Telkom Solo. This research uses simulation method to find the best solution for the company to decide the number of the servers. Thesimulation model is used because this model can give solution if analytic model is failed to do that. Analytic model cannot be used in this research since in Plasa Telkom Solo there are four kinds of service with different approximate time service.Based on the research, the best numbers of server is seven. Meanwhile, the service system model are combining service 1 (new setting and mutation) and service 2 (complain) with the number of server 5 and service 3 (information) combines with service 4 (cash payment and non cash payment) with number of server is 2. This model can reduce the queue time for 21,7325 minutes (before the simulation) to be 17,8694 minutes (after simulation). The time difference is 3.8631 minutes with utilization 0,8996 (89,96%) or 458,796 minutes (7,65 hours) per day and the free time for the server is 0,1004 (10,04%) atau 51,2040 minutes (0,85 hours) per day, in which per day there is 8,5 work time.

Penentuan Lokasi Ideal SD dan MI Se-Kecamatan Pejagoan Kabupaten Kebumen dengan Menggunakan Model P-Median, P-Center, dan Max Covering Ike Nurcahyono; I Wayan Suletra; Eko Liquiddanu

Pejagoan district is an outskirt near the central administration of Kebumen Regency. This position causes some people prefer to go to city for schooling. This condition becomes one of the factors for decreasing number of students that apply to Pejagoan district. Many schools lacks of students. Kebumen Regency education department has a plan to reduce some schools that do not fulfill the criteria of minimum number of students. Determining ideal location and number of schools has to be appropriate in order to does not cause problems in the future. In this study, the determining of location and the number of school in Pejagoan district are conducted by identifying the location and the distance of students’ house to the location of current elementary schools that considered as candidate locations. The school locations and optimum number of school are determined by using three models, p-center, p-median, and maximal covering model. These are conducted to identify the performance of each model and compare all of them. The calculation result concluded that p-median model is the most appropriate model to solve the problem. The optimum number of school is 26 and the average distance of students to the nearest school is 215.98 meters with deviation standard 138.08 meters, and the furthest distance is 1229.3 meters.

Rancang Bangun Alat Pemotong Bulu Ayam Untuk Mendukung Pembuatan Produk Shuttle Cock Daerah Pengrajin Serengan Kota Surakarta Lobes Herdiman; Eko Liquiddanu; Taufiq Rochman

Salah satu proses produksi shuttle cock yang kritis dalam arti dapat mempengaruhi kualitas produk adalah pada waktu pemotongan bulu ayam. Hal ini dikarenakan bentuk bulu hasil potongan dapat mempengaruhi bentuk cock itu sendiri. Selama ini pemotongan bulu ayam untuk produk cock dilakukan secara manual dengan bantuan alat gunting satu persatu sehingga hasil yang diperoleh sangat lambat dan memiliki bentuk cenderung beragam. karena itu pengusaha industri kecil memerlukan alat bantu pemotong bulu yang dapat digerakkan secara manual. Kegiatan ini mencoba membuat alat potong yang dapat membantu proses pemotongan bulu. Nilai tambah dari alat yang digunakan adalah adanya alat pemanas untuk membantu proses pemotongan bulu. Dengan alat pemanas ini bentuk potongan menjadi lebih rapi, dan dapat memotong tiga hingga lima buah bulu ayam.
