High number of vehicle theft and damaged vehicle caused climate factor such disasters on conventional garage has made an encouragement to the owners to decrease those risks. By using special access and by putting the garage down tothe basement can be trusted way to minimalized those risks above.This system works by communicate RFID reader and infrared sensor an inputs. RFID reader MFRC522 has a role as authentication tool for vehicle owners by manifest their card identities to the system. Meanwhile the infrared sensors IR-FC51 work as the input of automatic system. All these inputs will be proceeded by Arduino Uno as smart system data processor and ended by the movement of the dc motor as the lift motor and LCD as the information displayer.The registered owner card will get a special access to entering parking lot on basement, while the users that didn’t have registered card has no access to enter. Inside the lift, there will be infrared sensors to detect the vehicle on the lift and automatically will moved the lift upside or downside.

Server is a computer that serves a particular task in the network which can be used by other computers. The server damage will cause some losses in various parties who use the server services. Losses can be in the form of financial or others. The server damage can also be caused by natural disasters, such as earthquakes, floods, landslides and others. Therefore, it is necessary to create a portable server for VoIP and web server. VoIP servers are built by using asterisk as well as using the zoiper app and 3CX Phone to run VoIP. Meanwhile, the web server is created by using sentora panel. sentora panel is used because it has an installed packet like apache, php, mysql, phpmyadmin and other supporting software, hence it does not need to install it one by one. This portable server can be taken anywhere and can also be used in various PC or Laptop. So when the natural disaster occurs, the server stay safe, and ready to use.

The availability of bovine bone waste is very abundant and has not been utilized optimally as raw material for the manufacture of Hydroxyapatit (HA).HA is widely used in the field of orthopedics and dentistry, because it is biocompatible and bioactive, bovine bone wastes are synthesized by thermal-mechanical methods to obtain HA. The first stage of bovine bone preparation is done to obtain HA from bovine bone waste by mechanical collision to obtain bone meal smooth. The second stage of calcination at a temperature of 800oC. The results of microstructural observation with SEM obtained granules obtained almost evenly smoothness with average size 42.25 μm in span (irregular spherical (30.29-136.4μm) and chemical composition with XRF obtained by Ca / P ratio of 1.61, close to the optimal value of HA of 1.67.

This study aims to analyze and examine the effect of peak land acceleration value (PGA) on shear story using dynamic method of response spectrum. The PGA value and the spectrum response used are the spectrum responses issued by the PU ministry. The review is soft land in the citys in Riau. The results showed that the higher the story shear value, the higher the PGA value in each region. The areas with the highest inner and PGA grades are Pasir Pangarian (Rohul) and the lowest is Kota Selat Panjang (Meranti District). This is because the area of Rohul Regency is an area close to West Sumatera Province that has a high enough earthquake intensity when compared with Meranti Regency which is a coastal area located on the lower plains.

An antenna is a device that can receive electromagnetic waves at the receiver, and radiate electromagnetic waves on the transmitter. With the antenna we can receive information transmitted by the transmitting station through the receiver. In other words antenna helps in doing long distance connection with transmitter. In general, the antenna used to receive television signals uses many elements such as driven, reflectors, and directors. But in this study the antenna was made by using a parabolic reflector with a half-lambda driven dipole without using a director.Antenna is made there are several parameters measured as a proof of the success of the antenna. The parameters are: antenna gain, antenna impendance, VSWR (Voltage Standing Wave Ratio). The success of the antenna is also determined by the antenna's ability to receive a television signal which can also be seen by performing a direct test of the antenna.

Tobacco is one of the six most important commodities in Indonesia. This sector is the most strategic that can absorb millions of workers, ranging from tobacco farmers, laborers or workers to tobacco companies. One of the stages in tobacco processing is the drying process. Drying using sunlight is often distracted by erratic weather changes such as rain, this can cause the drying process to be slow and require very long drying time. Based on the above, a tobacco dryer was developed by implementing the fuzzy logic controller (FLC) method as the temperature controller and its moisture meter. This tool uses LM35DZ type temperature sensors and Soil Moisture YL-69 type moisture sensors. In addition, this artificial drying process also uses heating elements instead of heat from sunlight. Programming tool is made using Arduino uno microcontroller. When compared to conventional drying, the drying results using the tool will be superior in terms of time efficiency, human power and product quality.

Fiber from oil palm empty fruit bunches (OPEFB) can be used as a raw material for the production of composite board. Gambier can be used in a natural adhesive because of its high tannin content. Appropriate material to veneer the board and the correct temperature and pressing time are needed to improve the quality of this composite board. This research was to discover the optimal temperature, needed to make woven bamboo veneer composite board from OPEFB fiber and gambier based adhesive that can fulfill the Indonesian National Standards for veneered composite boards and the pressing time required for the board to reach thermal equilibrium. Results showed that both temperature and pressing time have a significant influence on density, moisture content, thickness swelling and modulus of rupture (MOR) of the boards but not on the internal bond strength or the compression strength parallel to the grain. Multi-layered composite board pressed at 1300C has weaker physical and mechanical properties than that pressed at 1450C, or 1600C. Twenty-five minutes of pressing time yielded a better product than 15 minutes and the combination of 25 minutes and 1450C proved to be optimal for the curing of the gambier based adhesive used with 8.4% moisture content fibers. Use of woven bamboo veneer resulted in boards that reached the density, moisture content, thickness swelling at 24 hours (PT24) and MOR National standards SNI 03-2105-2006 for standard veneered particle board however it failed to reach the standard for modulus of elasticity (MOE). The bonding strength of the boards reached the Nation Standard SNI 01-5008.7-1999 of 3.5 kg/cm2 minimum for structural veneered boards.
