Abstract

Maluku is one of the provinces in eastern Indonesia which is famous for its natural beauty. This is supported by the number of tourists who come there through Pattimura airport. With the increasing demand for air transportation at Pattimura airport at this time it is necessary to change the airport facilities specifically runways to accommodate all flight requests. Therefore, the thickness of the pavement of the runway must meet the strength of the structure so that it can serve the movement of the aircraft according to the age of the plan (in 2037). The purpose of the final assignment is to evaluate the strength of the pavement of the runway by comparing the flexible pavement design between the FAA Method and FAARFIELD Software. The data used are passenger data for 2011-2017, aircraft movement data, and runway layout images. Both of these methods will later be used as a reference in changing the thickness of the pavement according to the current condition of the existing runway. The total calculation results using a flexible pavement planning curve with CBR 6 for subgrade and CBR 20 for the subbase obtained results of 78,74 cm from the FAA method and 73,66 cm with the FAARFIELD software. The results of these two methods have a thickness greater than the current pavement condition of Pattimura airport, which is 68,58 cm. Therefore it is necessary to re-plan the thickness of the pavement so that it can accommodate aircraft movements at the planned age.

Abstract

The development of the number of customers in PT PLN (Persero) Rayon Kefamenanu increases every year. PT PLN (Persero) As a power supply company must be able to meet the electricity distribution to customers continuously. In preliminary observations of customers at PT PLN (Persero) Rayon Kefamenanu often experienced blackouts both in the number of outages and a long outage. This outage will result in losses for both the customer and PLN itself, so it is necessary to study the reliability of the distribution network system by calculating SAIFI and SAIDI.From the calculation of the SAIFI and SAIDI index values in 2017, 2018 and 2019, a comparison is made with the SPLN 68-2: 1986 standard values as follows: For the SAIFI reliability index values in 2017, 2018 and 2019 when compared to the SPLN 68-2: 1986 standards with the maximum value of the SAIFI standard of 3.2 times / customer / year is categorized as not reliable because the magnitude of the SAIFI count exceeds the SPLN 68-2: 1986 standard. For the SAIDI reliability index values in 2017, 2018 and 2019 when compared to the SPLN 68-2 standard : 1986 with a maximum value of SAIDI standard of 21.09 times / customer / year there is 2019 categorized reliable because the SAIDI calculation value is smaller than the SPLN standard value of 68-2: 198 and 2017 and 2018 are categorized as not reliable due to the magnitude of SAIDI calculated Exceeds SPLN 68-2: 1986 standards.While the large number of kwh losses that were not channeled due to disruptions that occurred in 2017, 2018 and 2019 at PT. PLN (Persero) Kefamenanu Rayon is: The value of ENS (Energy Not Served) in 2017 of 24,866.1 kwh or a cost loss of Rp 36,485,513,208. The value of ENS (Energy Not Served) in 2018 is 17,122.37 kwh or a loss in cost of Rp.25,123,311,0536.

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

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. Keywords: Energy Audit, IKE, IKA and PHE
