This research aims to 1 produce student worksheets making VCO enzymatically, 2 produce VCO enzymatically of fruits and leaf, 3 describe the feasibility, 4 describe result of students process skills observation in group and 5 describe the response of student worksheets has been developed. Development of student worksheets using 4-D models include define, design, develope, and disseminate, but in this study only conducted to develope stage. In the design stage begins with finding literature on proteolytic enzyme or protease contained in fruits and plants. After literatures study, conducted by making VCO based materials have been obtained.

Different methods based on Fourier transforms, zero-crossing Different methods based on Fourier transforms, zero-crossing detection, Kalman filters, phase-locked loops PLL and others are used for this synchronization. This paper presents a new PLL for synchronization of the output current of single-phase grid connected inverters with the utility grid voltage.
It is based on trigonometric transformations-sine and cosine functions in a phase detector block. The practical realization of the PLL is based on analog and digital programmable devices. Simulation and experimental results show good agreement with the results obtained by the theoretical analysis. Advantage of the proposed PLL is its insensibility to changes of the amplitude of the input signal after Save to Library.
In this article innovative low jitter low phase noise 7. Hence it can be achieved low phase noise and low jitter. The total dc power consumption is Design of hardened by design charge pump PLL. The PLL is a feedback system used to generate clock signal in microprocessors, and frequency multiplication FM etc.
The struck at single-event-effects SEEs such as latch-up, single-event-transient and multiple bit upsets which affect the PLL performance. The PLL and its components are implemented in cadence virtuoso tool using nm technology. Recently, it was recognized that the tail transistor fs Recently, it was recognized that the tail transistor fs CK D Q In this paper, a fast estimation method is proposed to obtain the maximum-likelihood estimation of the instantaneous frequency of the output wave of a voltage controlled oscillator VCO from a large signal network analyzer LSNA In this paper, a fast estimation method is proposed to obtain the maximum-likelihood estimation of the instantaneous frequency of the output wave of a voltage controlled oscillator VCO from a large signal network analyzer LSNA measurement.
A MHz device that is swept over a 4 MHz frequency range is characterized to show the applicability and the speed of the. This paper presents the design of 2 stages ring oscillator voltage controlled VCO , through phase degeneration of the load symmetrical cell, using local feedback networks, these feedback networks are implemented using the quasi-floating Ultra low power phase detector and phase-locked loop designs and their application as a receiver.
Detailed analysis of the mixer has been provided. Using the presented mixer as a phase-detector, a low Using the presented mixer as a phase-detector, a low power phase-locked loop PLL has been designed and fabricated.

Pembuatan Virgin Coconut Oil (Vco) : Pemecahan Emulsi Dengan Metode Ultrasonik
Download full text Bahasa Indonesia, 5 pages. Coconut tree is one of the strategic commodities which became the pre-eminent national. In addition to being one of the strategic commodities, coconut tree has many benefits start from the root, stem, leaf, fruit, up to they sheath. VCO is one product of the coconut plant has bigger added value and beneficial to health.
KONFIGURASI : JURNAL PENDIDIKAN KIMIA DAN TERAPAN
Making coconut oil was usually done with heating coconut milk for hours until the protein in coconut milk broke and the oil can go out from coconut milk emulsion. The aim of this study was to determine the effect of pineapple juice addition against the amount of produced oil, to determine the quality of VCO enzymatic were density, water content, organoleptic color, smell and flavor , teacher appraisal on work procedure and product of study result. The variation of pineapple juice shown that more pineapple juice addition then more produced VCO. The quality of three samples were for density which sample A 0.

PEMBUATAN VIRGIN COCONUT OIL (VCO) DENGAN METODE SENTRIFUGASI
Virgin coconut oil VCO which is also known as coconut oil or virgin coconut is coconut oil obtained from fresh coconut meat through a process of heating at low temperatures, freeze drying, fermentation, enzymatic, mechanical pressure or centrifugation. VCO has a higher commercial value because it has many benefits and efficacy, which is only used for food and industrial raw materials for the cosmetic treatment of the body hand body lotion , can also improve your metabolism and can cope with a variety of disease, thus used as ingredients in traditional medicines. One way of making the VCO is quite interesting by the enzymatic method using a protease derived from agave roots, and agave palado leaves. The purpose of this study was to examine the use of existing protease enzymes in plant roots palado, and agave leaves leaf palado as materials for VCO on enzymatic methods and and the determination of enzyme activity by Murachi method.
