Judul: Kajian Sistem Manajemen Keamanan Pangan pada Instalasi Pengolahan Air Minum - PT TKCM Mengacu Persyaratan ISO 22000: 2005
Abstrak: One of the most important task at any water treatment plant is safeguarding the quality of drinking water. PT TKCM as a regional water treatment company, has implemented ISO 9001 since 2005. Recently, this company moves toward to implement ISO 22000: 2005, in order to answer the needs of safe water supply. This study was conducted to assess the current condition at PT TKCM for preparation of implementation of ISO 22000:2005 with the specific purpose to assess the company's progress in the documentation, human resources, facilities and pre-requisite program implementation aspect’s base on FSMS - ISO 22000:2005 requirements. The study was conducted with several stages. The first step was gap analysis in documentation requirements. The second step was on site observation to collect data regarding aspects of human resources (HR),facilities and implementation of Pre-requisite Program (PRP) aspects. The third step was synthesizing recommendations base on the study result and the last was to develop the HACCP plan. This study was done through field observations, interviews, pretest and assesment using a standard checklist ISO 22000:2005, PAS 220 and pretest questions as tools. The results showed that the progress of company in the fulfillment of required aspect base on ISO 22000:2005 were (69%) in the documentation, (40%) in human resources, (69%) in facilities and (67%) in the PRP implementation. Therefore some rooms for improvement were needed to be taken for documentation, human resources, infrastructure and PRP implementation. HACCP Plan have been determined based on 12 step including 7 HACCP principles (BSN). Three processing step were identified as CCPs i.e.filtration, effluent control and post chlorination process.

Judul: Harmonisasi sistem jaminan mutu ISO 9001:2000 dan sistem HACCP ke dalam Sistem Manajemen Keamanan Pangan ISO 22000:2005 di PT Indoeskrim Dairy Food
Abstrak: Since food safety has become an important issue, every food tried their best effort to implement food safety management system to protect not only their customer but also the company's life. IS0 22000:2005 food safety management system was a latest system submitted by IS0 which is recognized world wide. Therefore many food industries that had already implemented HACCP and IS0 9001 made efforts to transfer their system to IS0 22000:2005 to simplify the system. The aim of this work was to develop a harmonization between IS0 9001:2000 aid HACCP system with IS0 22000:2005. Taken place at PT. Indoeskrim Dairy Food, this work presented a special discussion on analysis between the above three management systems, implementaton of a better sanitation program, development a proper coding system to establish a system with a good traceability for every product produced. To integrate both system a gap analysis was carried out and the gap was then fulfilled with OPRP, PIP, modified quality manuals, HACCP Table Plan and traceability system. According to IS0 22000:2005, a company had to fulfill certain sanitation programs which is required by the system. Company must also monitor the implementation of GMP and monitoring on OPRPS Traceability system is also required as a tool for the organization to solve and overcome problems from costumer. The basic principles for the system are easy to verified, consistent, result oriented, cost efficient and easy to apply.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
