Abstract

Many sites in Indonesia contain of soft soils which mainly located in farming areas, slopes, alluvials, low level areas. The main problem of soft soils for performing construction work is big settlement which is caused due to low ultimate bearing capacity of soils.These low bearing capacities occurred because of consolidation process proceeded in long time and slowly. To solve this problem the geotechnicians has tried to modify some methods to increase the ultimate bearing capacity of soft soils. There are many methods have been introduced and widely used for increasing bearing capacity. This paper discuss about four methods such as Bamboo Piles Method, Pre Loading Method, Vertical Sand Drainage Method, Geotextile Method.Bamboo Piles Method use bamboo as reinforced soft soils. Pre Loading Method used Pre Loading as the beginning loading. This loading aimed to conduct process of settlement in shortier time. Vertikal Sand Drainage Method required installation of vertical Drainage to clear sands on the soils layer. After draining and pre loading consolidation process was expected would be proceeding in shorter time. Geotextile Method used material of geotextile as tension force to reinforce soft soils so that the ultimate bearing capacity increased. The maximum bearing capacity would be obtained if users installed it as well as soil's layer condition.

Abstract

Various kinds of treatments given to solar panels illustrate efforts to increase the output power of solar panels and the efficiency of solar cells. In the following research, we will analyze the differences in the output power and efficiency of solar cells that have received different treatments. In the solar panel that will be analyzed in this study is the addition of a reflector to solar cells with a reflector tilt angle of 90 ° and 60 ° as a form of variation of radiation amplification. The idea for the use of a reflector is to increase the yield of solar cell input radiation. After testing, the output power produced by solar cells increases as the radiation received by the solar panels increases and the efficiency of the solar panels decreases as the temperature of the solar cells increases.

Abstract

The need for energy in the world continues to increase while the fossil energy source used continue to run out, so an alternative energy is needed to supply energy needs. Electrical energy is an indispensable energy. The sun (sunlight) is one of the renewable energy, it can be used to generate electrical energy. Indonesia is a tropical country, so sunlight is available quite a lot. To get efficient and safe (consistent) electrical energy, you can use solar energy that is backed up with PLN's electrical energy (hybrid system). The planned hybrid system uses 200 WP (11 units) Solar panels, 100 Ah 12 V batteries (1 unit), Hybrid controller system with 1000 watt inverter, 12 Volt 10 A Charger Control. In use, charging the battery current for 6 hours. The way this hybrid system works is that the voltage is read using the INA219 voltage sensor, which will be processed on the Arduino Nano, and forward it to the relay to regulate the power source used, and display how much voltage is on the LCD. When the battery voltage runs out, usually at night, or the weather is cloudy, measured at 11.2 volts or below, the relay will switch the source from the battery (inverter) to the PLN source, the relay takes 1 second. And when the weather is sunny or the solar panel is exposed to a source of sunlight, measured at 12.0 volts or above, the relay will replace the power source from PLN to the battery (inverter), and the relay takes 1 second.

Abstract

The use of electrical energy and water is very critical in the hotel industry because of almost all operational equipment support are uses electrical energy and most of the hotel operation using water. However the use of electrical energy and water should be used efficiently. According to Government Regulation No. 70 year 2009 Article 10 (1), that individuals, business entities and permanent establishments in energy supply activities are obliged to carry out energy conservation. This process includes an Energy Audit, which is a method to calculating energy use in a building where the results obtained to be compared with the existing standards so that it can be seen whether the energy use in the building is efficient or not. The standard used is the USAID-ASEAN Energy Consumption Intensity (IKE), which is 300 kWh/m2/year for the electricity standard and for the water standard is using USAID|Indonesia Water Consumption Intensity (IKA) which the standard for Bali area is 3.48 m3/room occupied/year. The Energy Audit at hotel Uma Ubud Bali is obtained an IKE of 207.78 kWh/m2/year and an IKA is 2.58 m3/room occupied/year so that it can be said that the use of electricity and water at hotel Uma Ubud Bali is likely to be inefficient, so an analysis of Energy Saving Opportunities (PHE) is needed. Energy Saving Opportunities at the hotel Uma Ubud Bali can be implemented in periodic AC maintenance, the use of motion sensors, replacing conventional water heaters with heat pumps, reducing the pool water pump operating hours, replacing inefficient light bulbs into LED light and maximizing of using grey water from waste water treatment plant to watering plantation and irrigating fishpond.
