Application of Time Management Systems in Tardiness of The Auditorium Construction Projects in The District Bone Bolango, Gorontalo Province Beby Sintia Dewi Banteng(*), Wanda Razzaq Uno (**) Civil Engineering Department, Universitas Negeri Gorontalo Jalan Jendral Sudirman No.6 Kota Gorontalo, Indonesia 96128 bebybanteng[at]yahoo.com* wanda_razzaq[at]yahoo.com** Abstract Time management is an attempt to complete a project. This is supposed to improve priorities, and effort to increase the efficiency and effectiveness of project management in order to achieve maximum results from available resources. All of that is to achieve the goals of a construction project, specifically success that satisfy the criteria of time (schedule), cost (budget) and quality. The aspects of time management consist of scheduling, monitoring, comparing progress in the field with scheduling, determining the effects caused at the end of completion, planning treatment to control the effects, updating project scheduling. Analysis of the calculations proves that in the late jobs, the crash program can be done by increasing the number of workers to minimize the duration that is too late. The monitoring can reduce the deviation between progress against the schedule. The monitoring includes measurement and work results (progress) of each activity, then the measurement results are recorded (Report) into a report form. The monitoring includes measuring and recording the results of work, recording resource usage, checking the quality of resources, recording performance and productivity, checking the possibility of emergence of new critical paths, corrective action and update schedules. From this study the results obtained by the completion of work using time management work in construction of auditorium building of the Bone Bolango regents office can be accelerated by 40%.

Study of Oos River Basin Characteristics for Sustainable Water Availability I G A P Eryani Faculty of Engineering and Planning, Warmadewa University Abstract Oos River Basin is one of the perennial river basin in Bali, whose water potential is widely used as raw water and irrigation water mainly for the Gianyar Regency. Even though it has great water potential, according to the BWS Bali-Penida (2012), 18.84% of its area is classified as critical land and 81.16% is classified as very critical. If it is not managed in an integrated manner, then this will have an impact on the sustainability of existing water availability. This study will examine the characteristics of river basins that are very important to be used to determine the condition of the river basin and how to maintain the sustainability of the existing water potential. The data needed in this research is Oos river basin boundary map data, Oos river basin river network map, topographic data, land use and maps of soil types. The results of this study will be in the form of Oos River Basin characteristics and river basin management recommendations for the sustainability of its water potential.

Margonda Raya, Pondok Cina, Kecamatan Beji, Kota Depok, Jawa Barat 16424 *nendra[at]pupuk-indonesia.com Abstract Factory turnaround maintenance projects are periodically carried out at the plant which will not only incur huge costs and consume resources but also result in loss of sales figures from non-operation of the plant during the implementation of the turnaround maintenance project. Maintenance activities or turnaround maintenance that exceeds the specified time, and unscheduled shutdown or unplanned shutdown events are factors that cause production loss and reduce the companys profit potential which ultimately leads to losses for the company. This research aims to Identify the variables in turnaround maintenance planning process contributes to the extension of the duration of the turnaround maintenance work. Identified variables obtained are input to risk identification and assessment process. Risk assessment process conducted carried out using expert judgment and qualitative risk assessment process. Risk assessment process results in identifying methods to shorten the duration of turn around maintenance and developing methods to optimize turn around maintenance work so that turn around maintenance work can be carried out effectively, according to the planned time and with good quality so as to increase the interval between turn around maintenance work which ultimately supports production efficiency based on risk.

Determining physical and operational factors influencing pipeline leakage location pattern in water distribution networks using spatial poisson point process Widyo Nugroho (a*), Nur Iriawan (b), Christiono Utomo (c) a) Doctoral Student of Civil Engineering Department, Sepuluh November Institute of Technology, Surabaya 60111, East Java, Indonesia *widyo.nugroho[at]gmail.com b) Professor of Statistics Department, Sepuluh November Institute of Technology, Surabaya 60111, East Java, Indonesia c) Associate Professor of Civil Engineering Department, Sepuluh November Institute of Technology, Surabaya 60111, East Java, Indonesia Abstract There are four pillars in leakage management strategy for water distribution networks, consist of pressure management, speed of recovery, active leakage control, and asset management. Leakage can be managed by applying the right combination of these factors in the right leakage management strategy. This study conducted in Malang City, East Java, Indonesia. The factors that influence physical water loss in the water distribution system are analyzed by focusing on the physical and operational parameters. The data in this study consist of spatial data and quantitative data. Poisson distribution in the spatial point process is chosen as the leakage point distribution approximation. From the analysis, it is found that the distribution pattern of pipeline leakage is included in the inhomogeneous Poisson process criteria, with two types of intensity area. Based on the results of parameter estimation, it is found that the high-intensity area is affected by speed of recovery, pipe diameter, pipe length ratio, supply discharge ratio, and pipe deterioration ratio but not affected by the energy demand ratio. While the low-intensity area is influenced by pipe diameter, pipe length ratio, supply discharge ratio, pipe deterioration ratio, and the energy demand ratio but not affected by the speed of recovery.

Rapid Application Development (RAD) Model Method for creating an agricultural irrigation system based on internet of things Adimas Ketut Nalendra, M.Kom (a*) M. Mujiono, M.Kom a) server administration and computer network, Blitar community college of Putra Sang Fajar Jl. Dr. Sutomo No. 51 Kota Blitar Abstract The development of the internet of things has penetrated in several lines, including in agriculture. To respond to the development of this IoT requires rapid technological adaptation as well. To build a system quickly, one can utilize the Rapid Application Development (RAD) method. The RAD system emphasizes the cycle of fast development designed and high-quality results from other methods. The problem is when building an IoT system using the RAD method, and the accuracy rate is low. The system was built using the minimum NodeMCU system with the help of a soil moisture sensor. The use of the RAD method in building an IoT-based agricultural irrigation system gives good results in testing all functions and equipment controls. The average delay level on testing IoT devices is around 4.6 seconds, so that the RAD method can be used as a reference in the construction of an IoT-based system Keywords: Internet of Things(IoT), RAD, agricultural, NodeMCU Share Link | Plain Format | Corresponding Author (Adimas Ketut Nalendra)
