Pineapple leaf fiber is currently widely used in furniture and handicraft industries because it is easy to obtain, inexpensive, does not endanger health, can reduce environmental pollution so that later on as a composite reinforcing fiber can overcome environmental problems The choice of epoxy resin as a base material is caused the strength and stiffness of Epoxy resins is greater compared to other types of polymers. This study was intended to see the impact strength of pineapple fibers resin-epoxy and the fracture material of the specimen with macro photographs. The test specimens used pineapple fiber with volume fraction, 10%, 30%, 50% and epoxy resin matrix and hardener as hardener. The specimen is made by casting and mica as a mold. Mechanical testing using impact test, Physical test using photo macro structure. The result of the impact study obtained the impact price on the fraction of 50% volume that is equal to 0.76 J / mm2, this occurs because the fraction of fiber volume of 50% in addition to the distribution of the uniform force by the matrix is also supported by the ideal fiber, from the results of the above research In Can the optimum fiber volume fraction is at 50% volume fraction.

Particle size and hardness of Al-10%wt.Ti powders due to the influence of ball diameter have been carried out using mechanical alloying techniques. The milling device used consisted of a Fritsch Pulverisette-5 planetary type ball mill with the rotational speed of about 360 rpm and balls size of 10, 15 and 20 mm. The materials used are stearic acid which was used as a process control agent, aluminum and titanium powders. A mixture of aluminum and titanium powders has the composition of Al-10wt.%Ti. The Al-10wt.%Ti powders, stearic acid and stainless-steel balls were added to the Fritsch Pulverisette-5 planetary in the argon gas environment. The weight ratio of stainless steel balls to the Al-10wt.%Ti powder was 20 : 1. The mixing time process was carried out for 5, 10, 15, 20 and 30 hours, respectively. Changes in phase compositions of these Al-Ti powders under different ball mill sizes were examined by XRD, and the optimum experimental parameter was obtained: the ball mill size was 20 mm. It was found that from the diffraction patterns of the Al-10wt.%Ti powders, the peaks of titanium begin to disappear with the increasing of the milling time, which indicates the increasing degrees of alloying of titanium atoms in the aluminum matrix. The microhardness test results showed that the hardness increases with increasing ball size.

R290 is a type of natural refrigerant that has ODP = 0 and GWP = 4. While R32 from synthetic materials has ODP= 0 and GWP = 675 both are refrigerants used in Split AC. With this high GWP, it can have a damaging impact on the atmosphere. The advantage of R290 is that it has a lower density compared to R32, which can save the number of fillings in the AC unit by ±30% of the previous amount of refrigerant in the same volume. R290/R32 was flammable with LFL= 2%/13% and UFL= 10%/33%. The purpose of this study was to analyze the performance of R290 as a substitute for R32 on an AC-split unit with a capacity of 9,000 Btuh/hr. The steps used in the test are that the AC unit is placed in an open room with ambient temperature around 32°/80°C. The test was carried out until it reaches the optimal and stable temperature, then data is collected. The results of data collection from the evaporator air temperature R290/R32 = 21.4°C/23.0°C, condenser air temperature = R290/R32= 35°C/38.5°C, suction pressure= 90 psig/130 psig and discharge 200 psig/420 psig. The test data were analyzed and calculated using the Mollier Chart software with the results = R290/R32 = refrigeration effect = 344.8/272.2 kJ/kg, compression work = 12.18/13.02 kJ/kg, COP = 28.3/20.9, compression ratio = 2.2/3.2, strong electric current 4.98/5.73 A. From the decrease in electric current of R290 obtained a savings of 13.3% was obtained when converted to electricity bill payment and get a profit of 45,886/month.
