Judul: Kajian Implementasi Regulasi Pemanis Buatan di Indonesia dan Studi Kasus Industri Rumah Tangga Pangan (IRTP) di wilayah DKI Jakarta
Abstrak: Artificial Sweetener is a food additive widely used by food industries especially in beverage industry. It can improve the taste, has low calorie and has stability at heating process. The aims of this study were to evaluate the data of BPOM registered foods using artificial sweetener during 1992 – 2007 and to conduct case study on implementation of artificial sweetener by home food industry (IRTP). Results of the study on registered foods showed that there was almost no change in the categories of food using artificial sweetener, before and after establishment of the regulation on artificial sweetener (Keputusan Kepala Badan POM RI Nomor HK.00.05.5.1.4547 tahun 2004 tentang Persyaratan Penggunaan Bahan Tambahan Pangan Pemanis Buatan Dalam Produk Pangan). However, it was increasing the number of food products that used artificial sweetener, for single artificial sweetener up to 116% and for combination increased 255%. Artificial sweetener is most widely used in powdered drinks, while sugar free candy used the most combination of artificial sweetener. Results of the case study on IRTP indicate that the understanding of the respondents about Good Manufacturing Practices (GMP) does not affect its implementation. The survey shows that 37,6% respondents are said to know and 52,4% knew the basic principles of food safety (GMP), but the results of observation in the field show less. Only 17% respondents got Good value, while 57% respondents got Fair value and 26% respondents got Poor value. Artificial sweetener used by 27% respondents consist of 23% using mix of sugar and artificial sweetener, and 4% using only artificial sweetener. Survey conducted in 7 chemical shops in East Jakarta and Central Jakarta showed that artificial sweetener was very easily obtained without distribution rules. The artificial sweetener that was sold freely in the market were sodium saccharin and sodium cyclamate, which were packed in sachet or bulk packaging.

Abstrak: Agricultural products as source of food must be safe to protect people from poisoning. According to the data, processed food become the source of food poisoning in 2001-2011. In Indonesia, processed food mostly produced by home industry. Therefore, it was necessary to study the safety assessment of food products produced by home industry. The method applied in this study was problem statement, collecting data and data analysis (determination of area of study, food product and issues on food production in home industry). The data showed that most home industry located in West Java. The products covered all types of NADFC food category and mostly flour-based products. Potential hazard found in flour-based products in West Java were the use of improper flour; use of hazardous materials, food additives excess, and microbial contamination; incorrect processing; packaging and labeling; and storage of food products. It found two types of product that should not categorized as products of home industry and did not comply with national standard.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
