Judul: Evaluasi kualitas produk dengan metode peta pengendalian di PT. Aspex Paper, Cileungsi Bogor
Abstrak: Banyak permasalahan yang dihadapi oleh industri pulp dan kertas, mulai dari bahan baku sampai dengan proses, masalah lingkungan, efisiensi serta penghematan energi; yang kesemuanya itu harus dicari pemecahannya. Salah satu masalah yang sering timbul adalah masalah yang berkaitan dengan kualitas produk. Masalah ini acap kali menyebabkan produk yang dihasilkan kalah bersaing dengan produk seje- nis dari pabrik lain. Dengan demikian pembinaan kearah kualitas merupakan suatu keharusan. Untuk memecahkan masalah yang dihadapi, khususnya pada aspek kualitas perlu diusahakan agar produk yang dihasilkan memiliki keseraga- man yang tinggi dan sesuai dengan spesifikasi yang berla- ku. Oleh karena itu metode pengendalian kualitas secara terpadu perlu diterapkan agar kualitas yang dihasilkan dapat ditingkatkan. cipta mile Sehubungan dengan hal tersebut, suatu penelitian telah dilakukan untuk mengetahui kualitas pulp dan kertas yang dihasilkan, sejauh mana keragaman yang timbul serta menge- tahui faktor-faktor yang mempengaruhi keragaman tersebut. Diharapkan hasil penelitian ini dapat memberikan input yang berharga kepada PT. Aspex Paper, Cileungsi, Bogor...

Judul: Pengendalian Kualitas Pada Proses Produksi Kertas Medium di PT Indah Kiat Pulp & Paper, Serang Mill
Abstrak: Paper with several sizes plays an important role in human life especially in modern society. Now paper becomes one of human needs and is used in various cases. With times, the paper consumption surely increases because of paper characteristics easily used, practical, light, cheap and can be recycled. Based on rising need of paper, it is a challenge for thefact01Y to increase the quality, capacity, and technology in the paper production. Qualified product is affected by production level through monitoring for each level of the production process. Quality management can be used for quality control, so that it can minimize product damage. The research was conducted at PT Indah Kiat Pulp and Pap~r, Serang mill (PT IKP P). The objective of the research is to identifY level factors of production process that influence final product quality, to analyze pelformance of production process, and main parameter of product quality by using quality management technique namely cause and effect diagram and control chart, identifYing the process instability systems and analyzing the correction process by using information ji-om observation, literature study and expert opinion in the research plant.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
