Abstract   

Trans Metro Bandung (TMB) is a mass transportation mode that was built as an alternative solution to Bandung traffic jam. The government felt that the TMB is the best transportation mode in order to solve traffic jam and pollution problem in Bandung city. Unfortunately TMB also became a source of conflict especially with the existing public transportation companies. This research purpose a combination of Graph Model for Conflict Resolution (GMCR) and value net of coopetition to analyze this conflict. Based on this analysis, possible steps in order to solve this conflict can be purposed.

Keywords: Graph Model for Conflict Resolution, value net of coopetition, Trans Metro Bandung, Conflict resolution

Abstract

According to Indonesian Republic Law No.32 2004, each local government has an obligation to design a high school student selection system that is suitable to be implemented in their region. Unfortunately, student selection systems that are currently implemented still cannot produce the expected result. We construct an agent-based model that mimic the student selection process in Bandung. By conducting experiments using this model, the limitations of current student selection system are identified and modification is suggested. By observing agent‘s success rate in this model, we also able to identify the best strategy for agent in order to be qualified in the school of their choice under different kind of system.

Keywords: agent-based model, computer simulation, student selection system

Agent Based Model of High School Student Selection System in Bandung, Indonesia

Dhanan Sarwo Utomo
Unpublished master thesis

Abstract

This Master degree thesis report discusses the development process of agentbased simulation for high school student selection system in the city of Bandung. Development of this simulation is motivated by the existence of schools which have lack of students on the other hand; there are many students who were rejected because the schools to which they enroll have lack of space. This simulation includes modeling of the applicant’s decision-making process in selecting school and, the interaction among the applicants in the exchanging information about the schools attributes. This simulation aims to explore the dynamics in the student selection system and, examining the impact of the applicant types proportion, the completeness of information possessed by the applicants and the number of clusters used to the enrollment distribution and the number of student deficit in each cluster. By conducting virtual experiments using this simulation model several suggestions to improvements to the student selection system that is currently applied can be made. In addition, the type of applicant that success more often is also able to be identified through these virtual experiments.

Keywords: agent-based model, computer simulation, student selection system

Perancangan Simulasi Berbasis Agen untuk Menganalisis Strategi pada Sebuah Sekolah

English Title: Design of Agent Based Simulation to Analyze School's Strategy
Author: Dhanan Sarwo Utomo
Published : Jurnal Pendidikan Inovatif Vol.4 No.1 September 2008

Abstract: School is an organization, which has certain goals to be achieved. Correct strategy analysis is essential in order to achieve these goals successfully. Interaction exists among students, teachers, parents and school managers within school organization. Each elements of this interaction have different goals and strategy to achieve their individual goals. Using hypothetical data we construct an agent based computer simulation to analyze interaction within school organization. Using this simulation, determine several scenarios that can optimize the outcome of school strategy.

Abstrak : Sekolah sebagai sebuah organisasi memiliki sejumlah tujuan yang ingin dicapai, salah satunya adalah tujuan pendidikan nasional. Oleh karena itu, pemilihan strategi yang tepat amat penting dalam kesuksesan pencapaian tujuan-tujuan sekolah. Dalam pendidikan, strategi ini umumnya dikemas dalam bentuk kegiatan siswa, kegiatan guru, peraturan sekolah, maupun metode belajar. Dalam organisasi sekolah juga terjadi interaksi antara siswa, guru, orang tua, dan pengelola sekolah. Hasil dari proses interaksi antarindividu akan mempengaruhi hasil dari pencapaian strategi sekolah secara keseluruhan. Interaksi antarindividu (agen) adalah fenomena yang kompleks karena tiap agen adalah manusia yang memiliki tujuan, nilai, strategi, karakteristik, dan emosi masing-masing.

Literature Review Agent-Based Simulation "On generating hyphoteses using computer simulation"

Conclusions that i get after I read article entitled "On generating hypotheses using computer simulation" by Kathleen M. Carley that was published in the Proceeding of the 1999 International symposium on commend and control research and technology.

What is the use of computer simulation?
  • Computer simulation can be used to develop the theory and generating hypotheses

Why computer simulation is important to generate a hypothesis?
  • Because, social interactions are dynamic, adaptive and non linear.
  • As an example of non-linearity is, the declining ability of an information to shift agent’s perception.
  • As the number of information that support an idea believed by an agent increase, the impact of dis-confirming information decrease.
  • Such non linearity will bring difficulties for the researchers to infer the impact of a learning process, adaptation and agent's response, especially in a dynamic environment.
  • Computer simulation can help researchers to think about the impact of such non linearity and to generate a number of consistent hypotheses.
  • To generate hypotheses using agent based simulation, researchers can conduct virtual experiment.
  • Obtained hypotheses then can be tested through experiment in the real world.

Steps to conduct good virtual experiment
  • Identify core variables: Core variables are parameters that are assumed to be the most relevant variables affecting the dependent.
  • Define the range of parameters that are going to be explored.
  • Set the non-core variables as random numbers or according to the real world data.
  • Run the simulation multiple times for each experiment set. Ideally researchers could obtain much larger data than, that can be obtained in real world experiment.
  • Analyze the result of simulation statistically.
What are the advantages of agent based simulation compare to the human laboratory experiment?
  • Using agent based simulation, researcher can explore range of parameters and type process that are impossible to be explored in the real world.
  • These impossibilities can be caused by the high amount of cost or by the ethical issues.
