Abstract

East Java art has a diversity of types and forms of performances. There are types of performances in the form of theatrical and ballet performances. This traditional art performance is intended to convey messages, advice, and past stories. This presentation is presented with various types of art so that between the types of theatrical or dance performances, each has a variety of needs for its stage and capacity. However, the lack of staging facilities is one of the problems that result in reduced artistic activities, so that some traditional arts in East Java are threatened with extinction. In this study, the purpose of this study is to look for patterns of flexibility in the auditorium to meet the needs of East Java art activities. The method used is the observation method. The observation was carried out by observing each type of East Java art activities to be accommodated, namely the type of traditional dance and theater. The selected arts are several art representatives who have the same type of performance. From the results of data analysis it can be concluded that the auditorium can at least adapt to 4 types of spatial configurations: arena, endstage, proscenium, and plaind stage.

Abstract

A higher of competition level requires each company to increase its competitive advantage to be a market leader. One of the options to improve the competitive advantage is to increase company performance efficiency since using this option, operational cost can be reduced. In this particular study, Lean Service concept is applied to eliminate waste that occurs throughout the value stream of bidding process in order to improve procurement performance in terms of its efficiency in PT XYZ. Lean concept implementation started from creating the Value Stream Mapping (VSM) to map current value stream along the bidding process continued with Process Activity Mapping (PAM) to classify waste that occurs throughout the value stream, Borda Count Method (BCM) to determine the critical waste and Root Cause Analysis (RCA) to find the root cause with risk analysis approach which can be used as a reference to determine priority of improvement. The goal of this study is work efficiency improvement in the bidding process by identifying its waste and its root cause since by recognizing those waste, improvement plan can be formulated. This study generates recommendations for improvement plan namely designing SOP which not only standardize its processes moreover set its time limit and improvement in the management system by increasing coordination with end user as well as upgrading procurement knowledge. Those result might be utilized by organization to increase procurement’s work efficiency.

Abstract

PT. ABC is a State-Owned company managing the electricity sector to meet the needs of the community in providing electricity in Indonesia. Electricity is a commodity that effects the lives of many people, so the basic electricity tariff (TDL) to the community is determined by the government. On the other hand, PT ABC's electricity main supply cost (BPP), are the responsibility of PT ABC itself. The achievement of PT ABC's profits is largely determined by how the BPP is managed and controlled. As of March, the BPP target of the PT ABC power plant managed by PT XYZ was not achieved with an increase in deviation of 27.47 Rp/kWh. The causes of and solutions to the increase in BPP could not be known immediately because PT XYZ did not yet have an analytical method that could explain the causes and their proportions to the increasing deviation comprehensively. Therefore, this study is conducted using the Variance Analysis method in the selection process. The result of this study is the development of BPP controlling method by identifying the BPP component deviations from the predetermined standard costs and suggesting better decision making in prioritizing the work program.

Abstract

In recent years, home-based enterprises have been giving significant implications for the economic improvement of the middle-low income community in Surabaya. With all of the limitations that exist, space, complex activities, and community acceptance become predictors that influence the formation of people-place relationship. Previous studies that tend to focus on the use of space are less concerned with the interaction undertaken by entrepreneurs which make them choose to continue their business where they have started. The dynamics of daily life in shaping social relations and functionality of place will affect how entrepreneurs perceive and assess their home-environment. Thus, it is important to highlight the process of the emerging attachment related to the use of a home for generating additional income. As the nature of place attachment which is multidisciplinary and socially constructed, this paper provides reviews on different paradigms, conceptualizations, and attachment types that should be used as analytical frameworks in the context of productive housing. A rich literature study aims to give further insight without ignoring the natural settings of the research context. By emphasizing the role of life experience of entrepreneurs, a more fruitful understanding towards accumulative assessment and perceived environment that triggers place attachment could be obtained in the future research.

Abstract

PT XYZ engaged in the electricity industry, which has a strategic issue that’s reduction of BPP (Cost of Providing) electricity as one step in supporting the holding company policy. With the target of reduction BPP, where one component of the BPP is maintenance costs. This research shows the priority of maintenance costs of each Units that can be used in the drafting of the RKAP. In order to prioritize maintenance costs, it is necessary to compile an analysis of the cost, start from the proposed maintenance costs of each unit (using the bottom-up method) until evaluating cost from management (using the top-down method). This top-down method is strengthened by the analysis of priority maintenance costs from the expert's view using the Analytical Hierarchy Process (AHP) method with the Expert Choice V-11 Software tool. Then the results of prioritizing maintenance costs from the bottom-up and top-down methods are carried out reconciliation through Forum Group Discussion (FGD). Based on the results, that the highest weighting factor was Productivity (0.616), followed by Area (0.320), Specifications (0.064). Whereas the sub factor that is very dominant globally is having low production costs and the highest priority Unit for maintenance costs is Unit E.

Abstract

Indonesia is the largest archipelago country in the world so that Indonesia's need for air transportation cannot be avoided. The demand for air transportation services increases in line with the increase in population and the level of welfare of the people. At Juanda Airport until the end of 2013 the number of passengers exceeds the capacity of the existing terminal. Overcoming this problem, PT Angkasa Pura I developed Terminal 2 of Juanda Airport, which began operating on 14 February 2014. With the development of facilities and flight facilities for Juanda Airport, aviation fuel supply needs have also increased. PT Pertamina (Persero) through the Aviation business unit as a provider of jet fuel at Juanda Airport, supports the development of the airport facilities. The investment carried out in 2017-2020 are the installation of a hydrant system pipeline for Terminal 2 and the addition of a storage tank to increase coverage days in the Depot Pengisian Pesawat Udara (DPPU) Juanda planned to begin in 2020. Until December 2019 the hydrant system project progress has reached 96%, but there has been a decline flight frequency since December 2018 due to partial closure of routes by airlines, reduction in flight frequencies and a decrease in jet fuel prices at market demand, so it is necessary to decide whether or not to continue investing in tank construction. Therefore, capital budgeting analysis is carried out using the incremental Internal Rate of Return (IRR) method between hydrant project investments and tank construction compared to hydrant projects without tank construction. The results of the incremental IRR analysis showed an IRR of 9.81% while the MARR used was 10.38%.

Abstract

The Interior Orientation is a set of parameters that have been determined to transform the coordinates of the camera photo. The pixel coordinates of Fiducial Mark in the base image (Search window) are obtained automatically. The template of the fiducial mark is designed on single-frame aerial photographs. The concept of photogrammetry with Image Matching techniques is applied in the programming works. The Normalized Cross-Correlation (NCC) method coupling with the Area Based Matching technique is precisely used in the automatic computation for measuring the coordinate of fiducial marks. Herein, three templates are provided for this calculation. The coordinates from the manual rectification are employed. The results reveal that the third template is more accurate than the others with the RMSE value of 0.0066. The accuracy regarding the results of manual rectification depends on the operator when they are identifying for pixel values.

Abstract

Success in completing projects on time is one of the essential goals, both for the owner and the contractor. XYZ Group, a holding of several companies in the real estate, has delayed more than 53% of housing projects. The impact of delays is time overrun, cost overrun, deviations in the quality, disputes, negative social consequences, arbitration, and idling resources. This paper studied a list of construction delay causes gathered from the literature. It starts by exploring factors causing project delays from the research and finding 48 causative factors, followed by distributing preliminary questionnaires to expert respondents to obtain 23 causes for housing project delays. The primary survey held on 55 respondents consisting of technical directors, project managers, project engineers, quality control, logistics, and project planners. Relative Importance Index (RII) calculated, and according to the highest values, the top five delay causes of housing projects are determined. Objectives of project delays from the owner and contractor are "Late issuing of approval of design documents by the owner," and "Changing government political/economic situation or policy." The cause of project delays from the owner is "Shortage of labour from the contractor," "Changes to work completed by the owner," and "Failure of the contractor to complete the work." Meanwhile, "Slow delivery of resources required by the contractor," "Changes in details by the owner," "Rework due to quality and final results by the contractor," is the cause of project delays from the contractor.
