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.

Judul: The Use of Sweet Modulator Flavor in Non-Alcoholic RTD Beverages and Its Market Potential in Indonesia
Abstrak: One of non-communicable disease that has high prevalence of occurrence is diabetes. In Indonesia itself, the prevalence of diabetes is increasing from 6.9% in 2013 to 8.5% in 2018. Whereas, diabetes can be prevented by increasing physical activity and having healthy diet by reducing sugar consumption. Sweet modulator flavor is a combined molecule created by XYZ company which can lowered the sugar application until 30% while maintaining the perception of sweetness in reduced-sugar product. The use of Sweet modulator flavor or called as Positive Allosteric Modulators (PAMs) has been already approved for food and beverage product application. By applying this Sweet Modulator Flavor, the prediction of total sugar reduction can be calculated. The market potential of this sweet modulator flavor can be predicted by calculating the market share (market value and market volume) to get market growth of each sugar-sweetened beverage product categories while also considering the new product launches of those categories. The research resulted that by applying the sweet modulator flavor, the total sugar reduction can reach 78 tons or around Rp 937,245,240.00 and product categories that has highest market potential is RTD Tea (2,281,400 L) followed by Fruit Flavored Drink (512,300 L), Carbonated Soft Drink (250,400 L) and RTD Coffee (118,300 L).

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
