" Jakarta International Container Terminal (JICT), which is the main international port of Indonesia, is overcrowded and is going to be expanded. Various expansion plans are considered, so the aim of the current paper is to simulate the plans using an agent-based modeling approach. The plans are treated as scenarios in the agent-based simulation model. Then, the throughputs from all scenarios are compared. The comparison shows that some of the plans can support the JICT vision. The results can be used as an input for the decision maker to either choose one of the plans or renegotiate the plans to achieve results that greatly support the JICT vision."

ABSTRACTJakarta International Container Terminal (JICT) is overcrowded and planned tobe expanded. Various expansion plan has been proposed. We try to find out possibleimplementation result by simulating those plans as scenario in agent-based logisticsystem simulation. The plans were translated as change in various parameter which inturn affect the agent’s behavior. The outputs are comparison of simulated JICTcondition post implementation measured by its throughput, based on each expansionplan. This comparison show that some of the plan close enough to match JICT vision.This comparison could be used as an input for decision maker to either choose one ofthe plans or renegotiate the plan to reach closest simulated condition compared toJICT vision.

"Model is a representation of a system. Through model, it can be easier to forecast and control the changing of each element system. Electricity distribution is also a system. Losses are general problem that exist in a distribution network system. But with the right methods, specifically technical energy losses can be reduced in order to increase the efficiency. By making model of the distribution network, the value of technical energy losses in the whole network as well as in every line can be observed. Simulation can also be used to see all losses reduction alternatives. By comparing results from each alternatives, the best alternative, which gives best result can be decided and implemented."

An Agent-Based Model was developed in order to simulate land use change in the Tehran metropolitan area, comparing the outcomes of each particular methodology. All methods are compared, and advantages and disadvantages discussed."

"Agent-Based Computational Economics (ACE) melihat interaksi dalam ekonomi dapat memberikan hasil yang tidak ekuilibrium sedangkan paham neoklasik melihat interaksi selalu menghasilkan ekuilibrium di dalam perekonomian. Dengan menggunakan sudut pandang ACE, salah satu asumsi dasar dalam ekonomi, yaitu asumsi constant returns to scale, dapat dilepas. Penelitian ini bertujuan melihat dampak pelepasan asumsi constant returns pada perilaku konsumen di dalam model Monocentric City melalui simulasi menggunakan model berbasis agen. Hasil penelitian menunjukkan bahwa penggunaan asumsi constant, increasing, atau decreasing returns pada model Monocentric City tidak memberikan hasil berbeda. Dengan demikian, bentuk preferensi konsumen tidak berpengaruh di dalam model Monocentric City.

Agent-based Computational Economics (ACE) sees interactions in the economy can produce outcome beside equilibrium whereas in Neoclassical views interactions always produce equilibrium. By using ACE standpoint, one of the basic assumptions in economics, namely the assumption of constant returns to scale, can be relaxed. This study examines the impact of relaxing constant returns assumption on consumer behavior in the Monocentric City model through simulation using agent-based model. The results showed that the use of constant, increasing, or decreasing returns assumptions did not produce different results. Thus, the different forms of consumer preferences have no effect on the Monocentric City model."

"Skripsi ini bertujuan untuk menilai kelayakan, sensitifitas, dan fleksibilitas investasi proyek pembangunan terminal pelabuhan internasional dari sisi komersial. Penulis menganalisis dengan menggunakan teori capital budgeting dengan cara menggabungkan tools seperti critical path method, business simulation, sensitivity analysis, scenario analysis, Monte Carlo simulation, decision tree, dan real option analysis. Dengan demikian faktor internal dan eksternal serta berbagai kemungkinan perubahan faktor-faktor tersebut dapat dikombinasikan untuk menghasilkan penilaian proyek, perencanaan keputusan proyek, serta pengelolaan risiko proyek saat ini dan di masa yang akan datang.Penulis menilai proyek pembangunan Terminal Kalibaru tahap satu layak untuk dilakukan karena memenuhi kriteria pengambilan keputusan investasi. Dari hasil perhitungan diperoleh variabel yang paling sensitif mempengaruhi kelayakan proyek, yaitu peningkatan pada bunga kredit investasi untuk bank pertama, mark-up pengadaan fixed assets, kurs, Penurunan kenaikan tarif sewa dermaga, kenaikan spread yang diminta oleh investor, dan kenaikan komposisi modal. Penggunaan real option analysis dalam menilai fleksibilitas proyek juga akan berpengaruh terhadap present value, yaitu menambah net present value dari proyek tersebut.The goals of this thesis are valuing feasibility, sensitivity, and flexibility of investment project on developing international port terminal from commercial aspect. The writer combines critical path method, business simulation, sensitivity analysis, scenario analysis, Monte Carlo simulation, and real option analysis. So, variability in probability of internal and external factors can be combined for valuing project, project planning decisions, include risk corporate management now and the future.

Findings from this study indicate that the development of the international port terminal is feasible to do, because the project meets the investment decisions requirement. Beside that, the author also finds the variables that have very significant influence are the project feasibility, like increasing in first investment loan interest rate, decrease in increasing terminal rent tariff, the mark-up of fixed assets, currency, increasing spread that is requested by the investors, and increasing in investment equity. The using of real option analysis in valuing the flexibility of the project will affect the net present value of the project."

"Pemesinan mikro merupakan teknik fabrikasi lanjutan untuk produk berukuran mikro atau memiliki akurasi dalam level mikro. Material yang digunakan pun tidak jarang berupa material lanjutan yang memiliki kekuatan tinggi dengan massa yang ringan seperti Ti-6Al-4V. Sebagai akibatnya, material tersebut memiliki sifat keras, getas, dan sulit diproses melalui pemesinan. Penelitian terbarukan menunjukkan bahwa pemberian getaran mampu meningkatkan kualitas dan kemampuan pemesinan untuk material-material dengan sifat tersebut, salah satunya berupa pemberian getaran longitudinal dan torsional (longitudinal torsional vibration assisted micromilling/LT-VAM). Penelitian ini akan mengamati proses pemesinan mikro dengan sistem LTVAM secara simulasi 3D. Pemesinan akan dilakukan dengan kombinasi kondisi kecepatan pemesinan dan jenis horn untuk LTVAM. Melalui pengamatan dengan simulasi 3D, penelitian ini menunjukkan bahwa penggunaan sistem LTVAM dengan horn yang memiliki torsionality tinggi memiliki potensi mengurangi gaya pemesinan hingga 35%, temperatur pemesinan hingga 9%, dan kekasaran permukaan hingga 27%.

Micromachining is an advanced microfabrication technique for micro-sized or micro-accuracy products. The materials used in micromachining are as advanced as it is, providing high-strength material while keeping its mass low such as those found in Ti-6Al-4V material. As a result, those mentioned advantages make them hard, brittle, and difficult to machine. Recent research articles had shown that vibration induction to the machining process can give a better machining quality to hard and brittle materials, one of which is longitudinal torsional vibration assisted micromilling (LT-VAM). This research is intended to simulate an LT-VAM machining process and how it compares to conventional micromilling. Several horn designs for LTVAM and variable speed will be simulated. Through the usage of 3D simulation techniques, the effects of LTVAM can then be measured. It has been shown that the application of the LTVAM system using a horn that has a high level of torsionality has the potential to reduce up to 9% of cutting temperature, 35% of cutting force, and 27% of surface roughness."
