Pineapple (Ananas cosmosus) has been proven to have many beneficial effects for health due to its bromelain content. The formulation of an instant drink form fresh pineapple juice to produce an instant drink product with high bromelain content was developed. A number of pineapple powder specimens were produced using a spray dryer with different formulations. Fresh pineapple juices were added with...
By the increasing production piston motor vehicle manufacturing industry, often experienced problems especially on old machines. Among them is the Out Diameter Finish (ODF) machine contained in the machining process. The Out Diameter Finish machine is used to determine the grade of the piston. Grade is the outer diameter of the piston grouping based on predetermined tolerance standards of the Out...
This paper presents RTL design of several blocks in MIMO WLAN system. Designs have to conform to multi-mode operation coexist and support backward compatibility with legacy WLAN defined by standard. Low latency, high speed, and low hardware cost implementation will be explained briefly in this paper. Furthermore, comparison with other works/designs also described to show our design advantages.
This paper describe a visual feedback control experiment for manipulator robot with camera on its hand using 2.5-D visual servoing control scheme. This scheme does not need estimate full 3D model of target object. Design of image jacobian matrix is separated between translation motion that using image based scheme and rotation motion that using position based scheme. The task of robot was approaching...
Fermentation food is known as one of traditional food processing method. This method is used in several countries. In Indonesia, fermented food that made by cassava is very famous in West Java area known as peuyeum or tape. Further aim of study is to control fermentation environment so that tape can be fermented at all area where cassava can be cultivated in Indonesia with better product and consistent...
In this paper, we report the simulation of floating gate MOSFET memory consists of Si/Ge/Si quantum dots for electronics storage nodes with high-к material as the tunnel oxide. Heterostructure quantum dot was proposed to maintain the good memory performance without losing the long retention characteristic. By replacing the SiO2 tunnel oxide with high-к material such as HfO2, ZrO2, and Y2O3 the leakage...
The main role of Rocket Navigation System is to deliver an attitude command to Flight Control System hence the rocket can be directed to a particular path or a specific target. This command is produced from Trajectory Planning algorithm. The Navigation System also performs attitude estimation by using the Extended Kalman Filter. The inputs of Navigation System are obtained from GPS, IMU, Pitot tube,...
This paper presents comparison on IV Characteristics analysis between Silicon and InGaAs PIN Photodiode. PIN Photodiode is a structure that is consists of positive region, intrinsic region and negative region (PIN). The thick intrinsic regions are a difference to a normal PN Photodiode. PIN Photodiodes practical as Photodetectors, Attenuators and Radio frequency (RF) switches. The simple, low cost...
This research will focus on options to reduce the complexity and cost of designing and evaluating smart homes by developing a residential environment and ambient sensor simulator that can respond to different movements of people. The map editor is used to create and save different types of floor plans, including existing furniture or appliances and to add ambient sensors in a 2-dimensional (2D) model...
Equivalent Circuit (EC) method gives a simple alternative method in FSS analyses which are useful for quickly predicting the characteristic of FSS. Impedance of the EC for a unit cell of the design Frequency Selective Surface (FSS) structure is investigated in this paper. The unit cell of the design FSS structure consists of FSS structures placed on the FR4, glass and hybrid (FR4+glass). The square,...
In this paper we discuss three types of Artificial Neural Networks which are commonly used in classification process. Those are Kohonen's Self-Organizing Map (SOM), Incremental Self-Organizing Map (ISOM), and Multi-Layer Perception Back Propagation (MLP-BP).
Indonesia with 240s million population is counted as a large population country. It is about 10% of that population is elderly with potential having cardiovascular problem. An alternative treatment to the people having that disease is by implanting a coronary stent either BMS (Bare Metal Stent) or DES (Drug Eluting Stent) types. Although, stent has been accepted as an alternative technique to treat...
We propose Constrained-Matching Pursuit Algorithm (CMPA) to improve detection performance of phase-coded radars. Matched filter response of weak targets cannot be used to detect the weak targets. We show that iterative matching pursuit algorithm imposed by a constrain that no two objects share the same range bin, capable to find them. A Matlab simulation of a radar employing 128 length code constructed...
The characteristic of artificial circular dielectric material in microwave engineering is studied. The study encompasses theoretical analysis of artificial circular dielectric, such as anisotropic permittivity characteristics, frequency characteristics and resonance mode in transverse electric mode when the material is used as a resonator encapsulated in circular waveguide. In paper present, using...
Mobile ad hoc network (MANET) is used in a wide range of application from civilian usage to military battlefield communications. Using multi-hop communication model, a source node can directly communicate with the destination node without infrastructure. Unfortunately, this feature causes the network vulnerable to various attacks. Security preventions implemented in the traditional wired network are...
Running is one of the recommended activities to maintain health. An improper technique may result in inefficient energy usage or injury. This research aims to design a mobile device that can analyze and process the parameter that is obtained from the running activity. The device uses accelerometer to measure running parameter. The subjects for this research are 20–22 years old people with non-athlete...
Density Functional Theory (DFT) calculations are carried out to investigate the ligands effects on porphyrin-based molecule in benzene solvent environment. Benzene solvent is modeled by PCM Tomasi. We are motivated to study the alternation of electronic and geometric structure of porphyrin-based molecule in the presence of ligands for achieving theoretical explanation about ligand porphyrin-based...
Research on ozone production by using silent plasma or Dielectric Barrier Discharge Plasma (DBDP) and implemented for microbial inactivation in rice has been done. The plasma reactor for ozone generating were reactor with multi-point-plane (MP-P) reactor and spiral-cylender (S-C) reactor configurations. The high voltage AC has been used with voltage up to 40 kV and maximum frequency 23 kHz. For implementation...
Clitoria ternatea (CT), is an herbaceous medicinal plant used to treat brain related disorders and dementia. The purpose of this study was to test the acute oral toxicity of the extracts of roots plant. Acute toxicity of Butterfly Pea Roots extract was evaluated in DDY-mice. The acute toxicity studies were adopted from OECD guidelines 423 and Lu (1995). The animals were orally administered a single...
