Abstract: |
LPG (Liquefied Petroleum Gas) is a highly flammable gas uses as the main household fuel source which component dominated by propane (C3H8) and butane (C4H10) as a result of conversion from crude oil. Fuels with flammable properties at room temperature need early attention or detection. An early warning and security system built to detect gas leaks in the household, serves as a solution to minimize the losses caused by these leaks. The solution given is a warning sound due to a gas leak using Raspberry Pi as main processor. |

Abstract: |
Bali’s water crisis, according to a study by The Bali Institude for Economic Development and Planning (IDEP) revealed that the water crisis in Bali is expected to worsen aswater supply in Bali just only 20 percent. Bali’s water crisis cause most of the population in South Bali use a deep wells and keep the clean water in the reservoir/water tank. The application of conventional techniques in measure water level automatically was inefficient and ineffective because difficulty in monitoring. This study offers one method in measurement of water level using ultrasonic sensor (contactless sensor). Sound waves generated from ultrasonic transducers are capable of measuring water levels in real-time and continuous, sophisticated, reliable, more accurate by using microprocessors as signal processors and at low cost. Real time measurement results show the measurement accuracy level with standard deviation of 0.71756 cm at the measurement distance from 5cm up to 150 cm |

Abstract: |
Authors have studied a rapid trajectory generation algorithm called “trajectory planner” for navigating in a highly complex terrain. The important attribute is the algorithm that enables to generate rapid and accurate collision-free trajectories based on the flight dynamics. The algorithm has mainly two challenges to achieve the objective. One is how to connect between the start (present location) and goal, and the other is how to generate the flight worthy trajectory. The former applies random search algorithm named “rapidly exploring random tree”. The algorithm grows the tree from the start to goal quickly. Then, the latter applies dynamics filter that constructs kinematics theory known as “inverse kinematics”. The novel guidance method is studied by fusing dynamics filter into random search. In this paper, the trajectory generation algorithm outline and real-time calculation results using on-board computer and the method for avoiding dynamic obstacles in small-scale unmanned aerial vehicle are described. |

Abstract: |
Music and dance forms traditionally used in theatre are classical because their treatise texts have been written in a more poetic way. All the historical legends and other stories are narrated usually in their text. The script has been written according to the Buddha Charitha (life of Buddha), with the intention of giving the audience an unique conception on Buddha‟s life, through using music and dance of classical nature, and also to create a distinctive space for this genre of theatre and a specific audience for it.
Besides, there is another reason for the use of classical music and dance in expressing feelings in lyrical theatre. In this case, the year 1900 becomes a special milestone view in Sinhala stage due to a number of reasons. First, the people who had been dissatisfied with Carnatik music in Nādagama, found the Hindustani music quite alluring.
The other reason is the new theatre genre became a semi professional theatre in the land. This situation influence to increase the income of the production. Therefore, this paper aimed to discuss the influence of music, dance and its expressions to increase the financial situation of theatre production.
source for primary data was the actual performances of particular plays. The secondary sources included the literature relevant to these areas. |

Abstract: |
Development has resulted in land use change, especially agricultural land which is economically profitable and has been converted into land for housing, roads and other infrastructure. Several assessment criteria conducted by the Agency of Regional Spatial Planning Coordinating (BKPRD) in filing land use allocation permits require weighting so that the feasibility land use change of agricultural land can be measured and technically accountable. The purpose of this study is to give a score and weighting index value on several criteria and sub-criteria for BKPRD assessment in submitting land use change, especially from the Technical Side of Irrigation and to build a decision support system for land use change of irrigation land in West Lombok Regency. Analytical Hierarchy Procces (AHP) (Saaty, 2000) is a decision-making approach designed to help find solutions to complex multicriteria problems in a number of application domains. This method has been found as a practical and effective approach that can consider decisions that are not structured and complicated (Partovi, 1994). AHP final result is a ranking or priority weighting of each alternative decision or called element. The results of the analysis using AHP indicate the weighting priority criteria in making decisions on land use change of irrigated land in terms of irrigation and agriculture. Based on the irrigation sector, obtained that a weight of 33.70% for irrigation water sources, 25.80% for technical irrigation management, 21.00% for irrigation management authority and 19.50% for irrigation channel types. While a review of the agricultural sector found a weight of 41.20% for land area, 39.70% for cropping patterns and 19.10% for farmer institutions. |

Abstract: |
The development of a region coupled with an increase in the pull of traffic movements should be directly proportional to the increase in transportation facilities and infrastructure. Development of the region without the improvement of transportation facilities and infrastructure will result in performance problems in the transportation facilities and infrastructure. The road intersection is the location of the source of conflict in traffic, one of them is Simpang Rembige Lombok, West Nusa Tenggara, Indonesia. With the construction of the Dakota road, it is expected to break down the flow of traffic from the Tanjung to Ampenan, so that it can reduce the tarffic volume at the intersection to be able to reduce congestion problems. In this study a review of the influence given to the construction of the Dakota road, the movement of vehicles at the current Rembiga intersection, the influence of the existence of the Dakota road on Rembiga intersection performance and knowing the performance of the traffic lights at the current Rembiga intersection and supposition when the road Dakota isn't there. By conducting a direct survey as a research method and analyzing data based on the equations in the factors that influence the characteristics of traffic, the influence of the existence of the Dakota road as an alternative route is anticipated that the queue at the Rembiga intersection is significant. This can be seen from the comparison between the total number of traffic movements from the West side (Adi Sucipto road) towards the North side (Dr. Wahidin road) with the total traffic movement across the Dakota road. During peak hours, the total volume of movement of vehicles utilizing the Dakota road as an alternative lane anticipates the queue at the Rembiga intersection of 662.50 skr from 1,532.78 skr or 43.22% with details of 374.80 skr or 24.45% moving from the side North to West and 287.70 skr or 18.77% moves from the West to the North. |
