This study aims to determine the effective shaft diameter in the design analysis of polishing machines in the manufacture of camshaft, determine the suitability of the V-belt, determine the service life of the bearing, determine the ability to accept seat loads. The method used in this research is the literature review method, namely by analyzing the primary data of the components of the tool to get the values that occur in the tool. The results of the calculation of the shaft suitability analysis obtained a suitable shaft with a diameter of 13 mm which has a rotational deflection smaller than the deflection limit of 0.061o < 0.3o. Based on the calculation of the V belt, size of the V belt selected is on the market, namely the V belt type A No. 37 with a length of L = 940 mm. From the calculation results, bearing is having a lifespan of 2603.838 hours. The strength analysis of the camshaft holder using the DS Abaqus software was found not to exceed the allowable deflection limit, namely: 2.736e-09 mm <0.417mm considered safe to be used. Meanwhile the analysis of the sandpaper seat is still lower than the limit’s value or 1.786e-09 mm < 0.694mm. Thus, the sandpaper holder is said to be safe in resisting the working forces.Kata kunci: camshaft, modification, shaft, v belt.

Electricity consumption level of construction or building can be determined by calculating the amount of electrical energy used in a certain time. This study aims to determine electricity consumption levelat KPKNL Kendari. According to the standards set by the 2000 National Standardization Agency for efficient energy for an office building is 240 kWh/m2. Refers to this standard, electricity consumption level of KPKNL Kendari was investigated. To aim the study goals, observation of load used and electrical energy was done. Various load used leads to electricity consumption which measured by dividing total electricity consumption to total building area, known as energy consumption intensity value (Intensitas Konsumsi Energi/IKE). Total electricity consumption for a year was 82,042 kWh and total building area is 913,8 m2. KPKNL Kendari’sIKE is 89.8 kWh / m2, this result shows that KPKNL Kendari electricity consumption Level is efficient. Keywords: Electrical energy, electricity cost, energy consumption intensity.

The stove is a fire-producing device to heat an object. Heating solid objects can be done directly on the fire or indirectly on the fire or indirectly by using the media stove. The purpose of this study was to determine the effect of adding copper wire to the stove wick on the performance of a used cooking oil stove with a mixture of kerosene. This research procedure is divided into several stages, namely first assembling the used cooking oil stove wick, then testing the results of the effect of adding copper wire to the used cooking oil stove wick with a mixture of kerosene. From the results of tests carried out from the results of data analysis, namely the addition of each copper wire the average temperature is always changing as well as the time. In this study, a good average temperature or it could be said that the temperature increased, namely the addition of one copper wire. So the addition of copper wire in this study greatly affects the temperature of the stove's flame. The characteristic of the flame produced by mixing used cooking oil and kerosene is reddish yellow in color. The characteristics of the flame produced by mixing used cooking oil and kerosene are reddish yellow with a maximum height of 11 cm - 15 cm in each percentage of the mixture. Keywords: Addition of copper wire, jelantah oil, kerosene
