ABSTRACT Compressive strength and split tensile strength are important parameters of concrete strength. This resarch was conducted to examine the effect of adding Sodium Tripolyphosphate (Na5P3O10) on the mechanical properties of Under-Water Concrete (UWC). Variation of Na5P3O10 used is by ading 5%, 10% and 15% of cement weight, and adding stone crush as filler at 10% of fine aggregate weight.…

Viewing visually path Rambutan there are road damage such as disappear, perforated, patch, and cracked so that inhibiting function road. The research aims to determine the type …
ABSTRACT In the construction of structure, concrete is the common material used nowadays. The easily content to get and have the high compressive strength make concrete have the plus one than the other material. While to time flies, concrete have much technology in the quality improvement. High strength concrete based on SNI-03-6468-2000 is the concrete that have high compressive above or sa…

ABSTRACT The door is a very important tool in the house or room, because the door is main part to protect the contents of the room. Therefore the door must have a security system. This door opener tool uses e-KTP as the door unlock access, then uses RFID RC522 as e-KTP reader in opening the key of the door from outside the room and the touch sensor as the door unlock from the room. This tool u…
ABSTRACT The use of room lighting that stays on when lights are not needed can lead to less efficient use of electrical energy. This study aims to create a device that can turn off and turn on the room lights automatically based on Arduino Uno which is triggered by human body motion, and generates a warning signal when the lamps are damaged. This research uses light sensor (LDR), motion sens…
