Abstract

The large consumption of electrical energy is usually influenced by the type of load used. Electrical loads have properties such as, resistive properties, inductive properties and capasitive properties. These properties have an impact on the electrical system that is the power factor. If the power factor is greater (active power) then the electrical system will be better result, otherwise. If the electrical system has low power factor or reactive power which will greatly affect the fuel consumption, so it is needed power factor improvement using capacitor. Electrical System of Passenger Motor Vessel Swarna Putri having a low factor that is equal to 0.619 and this research uses capacitors for power factor improvement. The result shows that the installation of capacitor causes the improvement of power factor to 0,8. The result of the calculation shows that the saving cost for energy per day decreases from Rp10,197,000 to Rp6,104,000Keywords: passenger motor vessel electricity, Power Factors, Electric Energy Consumption

Abstract

The utility of synthetic cleaners or commonly called as detergents have developed far indeed in this century. The effective and efficient use of detergents in cleaning process, was attracted to be used in laundry?s industry commercially, though, it has some drawback to the society and environments. Since the active materials in the compounds can cause irritating to the skins, cataracts to mature eyes and some other environmental issues due to the excess of foams can prevent oxygen dilution in the water so it be hazardous to water living organisms. Once the promising method to solve this problem is by photo-degradation using photo-catalyst. Photo-catalyst is the process using light and catalyst in order to accelerate chemical transformation, thus,  solar or uv-rays can be used as light sources. This research aims at to show the ability of catalyst TiO2 to degrade active material in linear alkyl benzene sulphonate (LAS) and alkyl benzene sulphonate (ABS) which is available in commercial detergent. Photo-degradation of LAS and ABS compounds was determined by optimum capacity TiO2 and irradiance time. Whereas, for environmental application, the degrade compounds such Rinso® and Wipol® was chosen since it is commonly used in daily life. Beside, artificial water waste and laundry water was chosen to show the environmental effect.  The result shows that the optimum number of catalyst TiO2 addition for LAS degradation was 1.5 g, and optimum time was 120 minute. Whereas  the optimum number of catalyst TiO2 addition for ABS degradation was 2.0 g, and optimum time was 120 minute as well. Thus, for detergent Rinso®, at optimum catalyst addition, we found degradation number was 75.83%, and for detergent Wipol®, at optimum catalyst addition, we found degradation number was 57.94%. Whereas,  for artificial waste at optimum catalyst addition, we found degradation number was 91.32%, and for laundry water waste at optimum catalyst addition, we found degradation number was 70.27%.Key words : Photodegradation, surfactant, TiO2, photocatalyst

Abstract

Syura dan demokrasi adalah dua kata yang sering diperdebatkan. Ada golongan yang menolak mentah-mentah demokrasi karena dianggap asing dengan Islam. Sebagian lagi berpendapat bahwa demokrasi adalah cerminan sistem syura yang diajarkan dalam Islam dan demokrasi sesuai dengan Islam. Bahkan ada yang lebih jauh menganggap Islam itu demokrasi itu sendiri. Artikel ini berupaya melihat persamaan dan perbedaan dari dua sistem pemerintahan tersebut.
