Pineapple Juice and amount of Sucrose on the Quality of Instant Noni Powder
Beverages, supervised by Zulkifli Lubis and Ismed Suhaidi.
Research was conducted to determine the effect of noni juice ratio with pineapple
juice and amount of sucrose on the quality of instant noni powder beverages. Research
was conducted in November - December 2012 at the Laboratory of Food Technology,
Faculty of Agriculture, University of North Sumatra, Medan, using a completely
randomized design, with 2 factors, i.e ratio of noni juice with pineapple juice (P):
(60%:40%, 65%:35%, 70%:30%, and 75%:25%) and amount of sucrose (S):
(30%,40%,50%, and 60%). Yield, moisture, total soluble solid, vitamine C, solubility,
organoleptic color, flavor and taste were observed.
The results showed that the ratio of noni juice with pineapple juice had highly
significant effect on yield, moisture, total soluble solid, vitamine C, organoleptic color,
flavor and taste, and had no effect on the solubility. Ratio of noni juice with pineapple
juice of (75%: 25%) produced the best noni instant powder and more acceptable. Sucrose
of 60% produced the best instant noni powder.95 HalamanSkripsi Sarjan
Effect of Ultrasonic Bonding Parameters on the Contact Resistance and Bondability Performances of CIGS Thin Film Photovoltaic Solar Panel
No full textThis article aims to investigate the optimal ultrasonic bonding parameter namely bonding pressure, bonding energy, and bonding amplitude that can minimize the contact resistance (R-c), maximize the peel strength, and identify the possible failure modes of ultrasonic Al bond on Mo back contact layer of copper indium gallium (de)selenide (CIGS) thin-film photovoltaic (TFPV) solar panel. The transmission line method was used to measure R-c and a peel test was carried out to measure the peel strength and the possible failure modes of ultrasonic Al bond on the Mo layer. Design of experiment using D-optimal method was utilized to evaluate the effect of the ultrasonic bonding parameter toward the R-c and peel strength of the Al bond on the Mo layer. Individual and combination of the ultrasonic bonding parameter have a significant effect on the quality of Al bonds on Mo back contact layer of CIGS TFPV solar panel. Possible failure modes could be identified through the application of the higher value of individual ultrasonic bonding parameter while keeping constant other bonding parameters and through the qualitative result of the load-displacement profile obtained from the peel test. However, sample 2 with bonding pressure of 3 bar, bonding energy of 20 Ws, and bonding amplitude of 7.7 mu m is the best-optimized bonding parameter window that can be applied to obtain ultrasonic Al bond with lower R-c and higher peel strength. It was noted that bonding pressure is the most sensitive bonding parameter followed by bonding amplitude and bonding energy.This work was supported in part by the Ministry of Higher Education of Malaysia under the Fundamental Research Grant FRGS/1/2020/TKO/UNIKL/02/10 and in part by the Universiti Kuala Lumpur under Short Term Research under Grant str19087.Zulkifli, MN (corresponding author), Univ Kuala Lumpur, British Malaysian Inst, Elect Engn Sect, Gombak 53100, Malaysia.

In helping farmers work to dry their agricultural products
So the author planned a heating machine and called it an injector burner.
This heating machine has supporting tools: - injector, nozzle
and other supports: - 90 cm long iron pipe, sufficient iron plates
because fuel oil is expensive and how to use fuel oil, the author
uses oil as fuel. How this burner injector works
is that the oil from the oil tank enters the oil filter after which it enters
the injection pump then the injection pump is pumped by the nockas which is rotated by the motor
The electricity then goes to the nozzle which is useful as a fuel booster.
This heating machine is as simple and practical as it can be
produces 1 liter of fuel in 1 1/2 hours. during
The use of this burner injector machine still has many shortcomings in its construction. So
continuous testing and experimentation to produce a product that is
getting better is very necessary.
During. From field observations there are several things that can be suggested
including: There are visible shortcomings on the part of the coordinator who is lacking
pay attention to the security and safety of pckci:janya. because there are still many
workers who are reluctant to use work security.
In the final project the author finds that planning work must be capable

ABSTRACT
The use of ESP8266 IoT technology as a wifi module that functions
as a medium for sending data through electromagnetic waves is often
used on electronic devices with a certain distance or scope.
The ESP8266 IoT wifi module has an onboard antenna with
omnidirectional properties with a working frequency of 2.4-2.5 GHz
(2400MHz-2483.5MHz) and a power output of +20 dBm. In its use it
becomes a problem if ESP8266 is used for certain directions in a
directional manner because the antenna properties installed on ESP8266
are omnidirectional.
In this paper the author wants to develop ESP8266 in terms of
directional transmission using horn antennas and yagi antennas with
measurements using VNA (Vector Network Analyzer) and spectrum
analayzer where the parameters to be taken are working frequency, S11,
VSWR, bandwidh, gain, and polaradiation antenna used.
From the testing of horn antennas and yagi antennas, the conclusion
is that the horn antenna is much better by referring to the results of 2.4
GHz, S11 -29.52 dB working frequency, 1.06 VSWR, 174MHz
bandwidth, and -35.2dB.
Keywords - ESP8266, directional antenna, horn antenna, yagi

No full textAbstract: A randomized complete design with 6 replicates of 10 birds per treatment (n = 60) was utilized to evaluate the effects of feeding corn dried distillers grains with solubles (CDGS) on growth performance, carcass yield and breast muscle fatty acid composition of chickens. A total of 300 male broilers (Cobb 500) were fed with different levels of CDGS (0% -control, 5, 10, 15 and 20%) in starter (age 0 to 21 day) and grower (age 21 to 42 day) diets, and weight gains and feed intakes were recorded. All diets were formulated isocaloric and isonitrogenous which met or exceeded the NRC requirements. At the end of the experiment (42 day) eight birds from each treatment were slaughtered to measure the dressing percentage, carcass parts yield and fatty acid profile of breast meat (from the left carcass side). Birds fed 5% CDGS had better (p<0.05) feed conversion ratio than those fed 10, 15 or 20%, but were not different (p>0.05) from control. There were no differences (p>0.05) in overall weight gain, feed intake, dressing percentages and carcass parts yields (% of carcass weight) among treatments. There were greater (p<0.05) percentages of linoleic acid (18:2 n-6) and elevated (p<0.05) polyunsaturated to saturated fatty acid ratios in chicken breast meat with increasing dietary CDGS. In conclusion, incorporating 5% of CDGS in the broiler diet did not affect (p>0.05) the growth performance and carcass yield. However, increasing the dietary CDGS increased (p<0.05) the percentage of linoleic acid and polyunsaturated to saturated fatty acid ratio in chicken breast meat
