Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.

Judul: Varieties of Peanut (Arachis hypogaea L.) Response on Weeding Frequency
Abstrak: The presence of weeds in peanut cultivation can suppress the growth, development, and productivity of peanut plants. The use of varieties and weeding is one of the efforts to suppress weed growth in the peanut area. This study aimed to study the response of several peanut varieties to the frequency of weeding weeds to compare the growth and yield of peanut plants. This research design used a factorial completely randomized block design (RKLT) consisting of two factors, namely peanut varieties (Hypoma 1, Talam 1, and Tasia 2) and weeding frequency (without weeding, 1x weeding, and 2x weeding). The results showed that the variety had no effect on the total dry weight of weeds, number of leaves, number of empty pods, plant fresh weight, and productivity. Weeding frequency treatment significantly affected weed dry weight, plant height, number of leaves, fresh and dry weight of peanuts, number of pods, dry weight of pods, and productivity. The 2x weeding treatment gave significantly different growth and productivity results from other weeding frequencies with the highest average productivity of 2.4 tons ha-1. The interaction of the two factors on the yield of peanuts had a significant effect on the total number of pods and the number of filled pods. The higher weed competition in peanut plants can suppress the growth and productivity of peanut plants

Judul: Efektivitas Pemberian Probiotik Cair pada Taraf Berbeda terhadap Fermentasi dan Kecernaan in vitro Ransum Sapi Potong
Abstrak: The aim of this experiment was to study the effect of liquid probiotic supplementation at different levels on in vitro fermentation and digestibility of beef cattle ration. The fermentability experiment used factorial randomized block design 3x4 with four replicates. Factor A was beef cattle ration without or with liquid probiotic supplementation at different levels: A1=control ration, A2=A1 + 0.1% (vw-1) liquid probiotic, and A3=A1 + 0.2% (vw-1) liquid probiotic. Factor B was incubation periods: 0, 1, 2, and 3 hours. The digestibility experiment used randomized block design with three probiotic treatments (A1, A2, A3) and four replications. The result showed that NH3, total VFA concentrations, bacterial population and digestibility were influenced by liquid probiotic supplementation at different levels. Incubation time influenced pH and those variables except digestibility; however, these treatments did not produce significant effect on degradability, protozoa and microbial protein synthesis. The result of polynomial orthogonal test showed that A3 is the optimal treatment.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.

Judul: Kinetic of quality changes of pineapple juice during aseptic process
Abstrak: Kinetics and phenomena of the changes of pineapple juice quality were studied. Rheology of pineapple juice at high temperatures was also observed. Kinetic parameters were investigated based on the holding tube temperature of microthermic apparatus used for aseptic processing study. The treatments were processing times and temperatures, i.e. in the ranged of 0-60 second and 87-96 OC, respectively. The kinetic parameters obtained from the experiments were used to optimize the aseptic processing of pineapple juice. The results showed that ascorbic acid content decreased during aseptic process while browning index increased. The change of ascorbic acid content was succesfully described by second order kinetic model, whereas the increase of browning index followed zero order.

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.

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.
