Abstract

The particle board was made based on mixing durian skin and sugar cane bagasse with urea formaldehyde adhesive. The variations the composition of mixing durian skin, sugar cane bagasse with urea formaldehyde adhesive used among other: 35%:35%:30%, 30%:30%:40%, and 25%:25%:50% and printing time and pressing for 24 hours. The parameters of the testing include: Modulus of Rupture (MOR) dan Modulus of Elasticity (MOE). Analysis of the mechanical properties of the particle board produced at the composition of 35%:35%:30% which has a value MOR = 446,17 kgf/cm2 and MOE = 160,9 kgf/cm2, at the composition of 30%:30%:40%, has a value MOR = 1369,57 kgf/cm2 dan MOE = 3903,3 kgf/cm2, at the composition of 25%:25%:50%, has a value MOR = 1463,07 kgf/cm2,  dan MOE = 3342,1 kgf/cm2 which matches SNI 03-2105-2006 criteria type 8 is not required.

Abstract

Temperature is the level of heat in an object and one of the variables that gives an influence on the value of an object's electrical resistance. The value of electrical resistance affects the conductivity of objects. This study aims to determine the change in the value of resistance in the wire connected to the heater. The benefit of this research is to provide information to the public about the effect of temperature changes on the value of electrical resistance. This study uses an experimental method by measuring the resistance values on wire 1 and wire 2 which are at room temperature and influenced by heat sources. Changes in temperature towards higher values make free electrons in the wire move faster. The higher the temperature value, the higher the value of resistance produced by the wire.

Abstract

Swimming pools have the potential to cause health problems if not properly maintained, one of them is by maintaining the swimming pool water pH. pH is very important as a parameter of water quality, the acidity is called neutral if the pH value is 7, the value of pH <7 contains acids and pH > 7.8 contains bases. therefore designed a pool level pH control tool based on light intensity and rainfall. This tool aims to produce a neutral outdoor swimming pool water pH, able to design water pH measuring devices using light intensity sensors and rainfall sensors based on ATmega32 microcontroller and analyze the effect of swimming pool water quality on health. Tests carried out with aquarium prototype and measurements carried out for 1 day continuously. The test results show that this tool is able to neutralize the pH of swimming pool water by producing pH 6.8 and 7.1.Thus, the tool designed is efficient in providing information on the acidity of swimming pool water pH and can neutralize pH levels.

Abstract

A pulp-based ceiling board has been made. Variations in the composition of mixing cement and pulp used include: 70%: 30%, 60%: 40%, and 50%: 50%  and Variations in the composition of mixing cement, sand and pulp used include: 50%:20%:30%, 40%:20%:40%, 30%:20%:50% with FAS 0,4 and the printing and pressing time is 24 hours. The parameters of the test include: water absorption and density. Analysis of the ceiling board physical produced in sample A with a composition of 70%: 30% has a water absorption value = 19% and density = 1.58%, in sample B with a composition of 6%: 40% has a water absorption value = 26 , 8% and density = 1.53%, in sample C with a composition of 50%: 50% has a water absorption value = 26.05% and density = 1.45%, in sample D with a composition of 50%:20%:30% has a water absorption value = 24,3% and density = 1.67%, in sample E with a composition of 40%:20%:40% has a water absorption value = 20,9% and density = 1.45%, in sample F with a composition of 30%:20%:50% has a water absorption value = 14,8 % and density = 1.34%.

Abstract

Motorcycle theft cases are increasing lately. However, the level of successful case disclosure by the police is classified as minimal. One of the reasons is the difficulty of the investigating team to locate the stolen vehicle. One solution that can be done is to install a tracker on a motorcycle. With the development of technology, we can use GPS devices as a tool to track vehicles from theft. The general objective of this research is to reduce the crime rate of motorcycle theft that currently occurs in Indonesia. The specific design objectives are: (1). Facilitate the security apparatus (2). Eliminate public anxiety about motorbike theft cases. For that we need a better security system as a safety for motor vehicles. This tool is equipped with features or services that support services on motorbikes, namely: SMS / SMS Gateway/ SIM800L Module, ATMega328 Microcontroller, GPS (Global Positioning System) Module, and other supporting devices. This tool is connected to an Android device with a GPS tracking system by showing the location of the missing motor vehicle. It is hoped that this security system design can increase the level of security and reduce cases of theft in motor vehicles. This system has also been tested on motorbikes with good results.
