Judul: Mempelajari Pengaruh Penambahan Hidrokoloid Terhadap Karakteristik Nugget Tempe
Abstrak: Tempe nugget is one of solutions to increase the value of tempe and diversification in making process. Texture is an important quality specification in meat product because it will determine consumer acceptance. Therefore, this research used hydrocolloid as binding material to improve the texture. The aims of this research are determination for proper formulation of tempe nugget added chicken meat based on organoleptic test, investigation for characteristics of tempe nugget using hydrocolloid, and raw material cost analysis for the choose product. This research was divided into two parts. The first part is trial for tempe nugget and determining the best formulation. The second part was adding three types of hydrocolloids (sodium alginate, CMC and guar gum) with conc. 0%, 0.5% and 1% against the best formulation and analyzing the quality. The results showed that the best formulation of tempe nugget based on organoleptic test was nugget tempe with 60 part of tempe and 40 of chicken meat. Tempe nugget with hydrocolloid added based on physic analysis was having pick up predust (5.19±0.44)-(5.82±0.19)%, pick up batter (20.16 ±1.18)-(23.57±0.12)%, pick up breader (12.27±0.56)-(14.58 ±0.15)%, cooking loss (1.40±0.03)-(2.18±0.22)%, hardness (2607.43±42.67)- (4926.70±77.15) gf, and elasticity (0.68±0.01)-(0.73±0.01). The breader loss of samples was high in the 1st cycle and decreasing in 2nd to 5th cycle. The most preferable tempe nugget based on organoleptic test is tempe nugget with CMC 1% added. The proximate analysis for the choosen product was 49.47% moisture, 1.84% ash, 12.62% protein, 15.51% fat, and 20.57% carbohydrate. From raw material cost analysis got the tempe nugget price lower than chicken nugget.

Judul: Pengembangan Nugget Berbahan Tempe Busuk (Over-Fermented) untuk Remaja.
Abstrak: Tempe merupakan salah satu produk fermentasi asli Indonesia. Di luar berbagai efek fungsional kesehatannya, karakteristik tempe yang mudah rusak menghambat pemanfaatannya secara luas. Seringkali menjadi terlalu difermentasi dan tidak dikonsumsi lebih lanjut. Fermentasi lanjut ini masih menyimpan senyawa nutrisi yang cukup signifikan, terutama kandungan proteinnya. Penelitian ini bertujuan untuk mengembangkan nugget berbahan baku produk tempe busuk. Nugget dipilih karena cukup populer di kalangan masyarakat. Seratus gram tempe fermentasi lanjut mengandung protein, lemak, karbohidrat dan serat masing-masing sebanyak 16,65g, 11,86g, 6,79g, dan 11,08g. Rancangan Acak Lengkap (RAL) dengan dua kali ulangan dan tiga jenis perlakuan digunakan pada penelitian ini. Tiga taraf proporsi tempe busuk dengan tepung terigu yang diterapkan pada formula adalah F1 (1:2), F2 (1:1) dan F3 (2:1). Uji penerimaan dan preferensi dilakukan untuk mengevaluasi parameter sensorik formula dan selanjutnya digunakan sebagai kriteria pemilihan formula. Hasilnya menunjukkan bahwa formula dengan F2 (1:1) tempe busuk terpilih sebagai formula terbaik. Analisis proksimat membuktikan bahwa nugget tempe busuk mengandung protein yang signifikan yaitu 16,57% yang memungkinkan 11,05-16,58% dari kecukupan protein harian untuk remaja.

Judul: A Continuous Vaccination Strategy in the SVIR Epidemic Model
Abstrak: Vaccination is conducted to minimize the spread of a disease. The vaccination is usually done several times within a fixed time interval. In the SVIR model, it is assumed that individuals do not get immediate immunity following a vaccination program. So according to process of vaccination on SVIR model, there are two strategies, i.e. the continuous vaccination strategy (CVS) and the pulse vaccination strategy (PVS). In this study, only the CVS strategy in epidemic model SVIR is considered. Results of the study indicate that dynamics of the CVS system depends on the basic reproductive number. If the basic reproductive number is less than one, then the disease-free fixed point is asymptotically stable. It means that the disease will eventually disappear from the population. Conversely, if the basic reproductive number is greater than one, then the endemic fixed point is asymptotically stable, which means that the disease will remain exist in the population. Simulation result shows that the vaccination would minimize the spread of disease by reducing the basic reproductive number. If the time for the vaccinated recipients to obtain the immunity, as well as a possibility of vaccinated recipients to be infected are neglected, then the disease will be eradicated. This condition is called an over-evaluating effect of vaccination.
