wire_tapping_07Playback recorded conversations between Anggodo Widjojo with various parties have revealed the occurrence of engineering criminalization of KPK. In fact, the effect of playing recordings of conversations that wiretapping is much greater. This tape has forced Deputy Attorney General, AH Ritonga and Police Headquarters Kabareskrim, Komjen Susno Duadji resign, because his name was mentioned a lot in conversation Anggodo.

Many people wonder how it actually intercepts conducted, and how well the signs of bugged phone. Moreover, tapping not only the officials, but it can be done to anyone.

Actually, not too difficult to identify whether our phone was bugged people. Here are some simple ways to recognize the symptoms.

  1. If your phone battery drained faster when rarely used, you should be suspicious. Therefore, a spy software (spyware) that is embedded in the phone, usually will send the information to the wire. This causes the phone battery will drain faster. Read more

handwashingHands is the main medium for the transmission of germs that cause disease such as diarrhea and respiratory diseases. From various research, the risk of disease transmission can be reduced by an increase in the behavior of clean and healthy living, hygiene behavior, such as washing hands with soap. Wash hands with soap is one of the most effective way to prevent bird flu, swine flu, diarrhea and pneumonia. Each year, more than 3.5 million children can not live up to the age of 5 due to diarrhea and pneumonia. Unicef says washing hands, especially after contact with feces can reduce diarrheal diseases by more than 40%, and reduces respiratory infections by 30%. Read more

Laboratory Equipment Cleaning

beakers-300x256Cleanliness of laboratory equipment, whether in the form of equipment or non-glass container glass such as polyethylene, polypropylene and Teflon, is a very fundamental part of laboratory activities and is an important element in quality assurance programs.

Attention to the cleanliness of these items should be improved and should be proportionate to the level of interest test, the required measurement accuracy and decreasing the concentration analit to be determined.

Each laboratory should establish adequate procedures for cleaning equipment and non-glass cups that are used in a variety of tests. If a particular test methodology requires a specific cleaning procedure, the procedure must be followed.

How to Clean General Laboratory Equipment
The process of cleaning must be done immediately after the equipment is used. Disposing of hazardous materials and corrosive cleaning equipment is cleaned before. Washing equipment must be manually or automatically using a suitable detergent to use. Read more

The Series of Earthquakes in Indonesia

Large-scale earthquake will knock down anything on earth that unsound and fragile. This phenomenon is not just demolish the building, but also makes landslides, broke, and ambles. Beyond that, an earthquake of the coast is also a potential cause tsunamis. That is a series of threats to the population in the earthquake-prone areas.

As long as the earth rotates, the movement of plates covering the earth and float on the magma will never stop. Between plates of collision or the crust is what causes earthquakes continue to occur after another all over the world.

When one location in the boundary layer of rocks collapsed due to the earth’s crust holding the pressure plate merapuh, rocks that would seek a new stable position. During this process will be a series of aftershocks, the main pascagempa. This can result in cracked buildings and fragile finally collapsed.

For earthquakes in Padang, 30 September, hack earthquake even hundreds of times before the incident. Since the earthquake in Aceh, December 26, 2004, Padang and surrounding areas are often hit by earthquakes scale 4 to 6 on the Richter scale. “The numbers in the hundreds,” said Sujabar, officials at the National Earthquake Center Meteorology, Climatology, and Geophysics.

“Consumers told us that they want the protection of security software at once, but we know that one problem is that the product is not available or not able to buy, so they gave up to give protection.”
Microsoft hopes this free software will be downloaded extensively, especially by those who do not keep their computers in order to be protected from hackers and the road was “improving security throughout the ecosystem are included in Windows.” Read more

Natural Gas Flow Measurement

Posted on | October 2, 2009 | 1 Comment

In the measurement of gas flow rate, there are several types of systems-meter (gauge) commonly used, among others:

1. Diaphragm Meter
2. Turbine Meter
3. Orifice Meter
4. Ultra Sonic Meter (USM)

Diaphragm Meter

Diafragh Meter

Diaphragm Meter

Diaphragm meter is usually used to measure the gas consumed by households, small commercial firms and other consumers. With these tools necessary gas pressure and low flow rate. This tool is able to measure accurately the volumetric flow in the overall value and does not require any additional energy source (electricity). The problem faced only if the pressure is too low and is unable to rotate or move the recorder, which should have a minimum pressure for operation. Maximum working pressure of about 1000 mmH2O.
This tool consists of the machine:

  1. Diaphragm that divides the two parts with 4 drive gas flow will move the field diaphragm, forwarded to the shaft (lever) and play the recorder (counter). Style that encourages the flow of gas turns diaphragm field, resulting in movements that rotate around the needle recorder. Materials used for the diaphragm of oil resistant rubber imitation.

How to Use Planimeter in Natural Gas Flow Measurement

Posted on | September 28, 2009 | No Comments

Orifice meters used to measure the volume or flow rate of natural gas, in addition to using computer flow units as a means of output data, also prepared a back up facility Chart Recorder. This chart used to record fluctuations Static Pressure (P), Temperature (T), and Differential Pressure (DP) for 24 hours. To be able to know the amount of each transmitter used a planimeter aids. This tool is more commonly used as a tool to calculate the area of a region on a map.

Chart Recorder

Chart Recorder

Flow / Chart Recorder is used as a backup tool for electronic flow measurement computers on meter system, both in customers and with the supplier (off-take). Chart Recorder is commonly used brand of ITT Barton or Foxboro.

These types of recorders are distinguished on the basis of the number of pen used, some systems that use charts include:

  • Recorder pens 2 (P + DP)
  • Recorder pens 3 (P (blue) + DP (black) + T (red))

where:
P: Pressure
DP: Differential Pressure
T: Temperature  Read more

Corrosion, Serious Problem in All Countries

Posted on | September 28, 2009 | No Comments

corrosion2Corrosion or rust occurs continuously without stopping. There is no materials that could avoid corrosion. Corrosion occurs because caused by a process that occurs in elekrtokimia metal or alloy caused by the presence of electrolytes (liquid / acid solution, salts, minerals that can deliver electricity / conductor).

A result of material / metal degrades the quality deterioration of the physical quality material becomes brown / rust that strengthen the effect of the material also decreases. Indonesia has never calculate quantitatively the amount of loss due to corrosion. But the amount of corrosion losses in the U.S. reached 15 billion dollar per year or about 15 trillion rupiah. If the Indonesian state budget is 30 trillion per year, the loss of corrosion in the United States is equal to half the value of our state budget per year. If losses due to corrosion attacks in Indonesia, approximately 10% of the American losses amounted to 1.5 trillion rupiah per year, not including lost production hours, damages, claims, repair costs, and others.

If Indonesia can prevent corrosion damage only 0.5 trillion per year, then every 2 years will come new jobs for citizens of Indonesia. Merely illustrative, not rare night bus or pickup truck lost control due to brake free from tension due to leaking hydraulic pipe corrosion attacked. Passenger-laden ship sank due to a leaky plates attacked by corrosion, aircraft failed to land because the “landing gear” is not working due to leaking hidrolisnya system. All of this type of accident causing damage very large material loss of life, body and morale that can not be measured in money.

Corrosion attack is obviously a very big danger, even bigger than the consequences of natural disasters, but because of our commonness of the corrosion attack of evil and danger that such a large loss that occurs without any of us realize or know. Ironically we willingly accept all the risk of loss. The easiest example for instance if the car’s exhaust / motor we leaked, at least with a little grumbling we bring the vehicle to the garage to repair or even replace it with the cost is not cheap. Whereas corrosion attack can be prevented so that the cost does not become very expensive. That’s why a corrosion engineer always reminded that “Prevention of corrosion in many ways is a long-term investment”

Don’t Brush Teeth Immediately after Drinking Softdrink or Juice

Posted on | September 20, 2009 | No Comments

softdrinkFor fans of the drink cola or orange juice noticed this appeal. German pharmacists association recommends 30 minutes of waiting time if you want to brush after drinking cola and orange juice.

High acid content of two drinks can lead to damage tooth enamel. Waiting for half an hour is ideal for tooth enamel is hard enough than just consume two drinks. Rules toothbrush after 30 minutes of juice or cola drinks should not be ignored. Juice beverages except fruit juice is very acidic peach compared to coffee drinks, tea, beer or wine to lower acid levels.
Earlier researchers at NYU College of Dentistry has launch his discovery that a lot of sports drinks sold also contains citric acid can damage the teeth.

This research was conducted by soaking the teeth for 90 minutes, as a simulation for those who like to drink sports drinks throughout the day. It turned out some tooth enamel is gone.
This is because sports drinks are leaked to the bottom layer of enamel, causing the teeth become soft and weak. This condition is called dental erosion could easily result in damage and loss of teeth if not treated immediately.
