Abstract

Value engineering is a decision-making process based systematic and structured multi disclipinary. Drainage is a disposal water mass media in natural or artificial from the surface or subsurface of a place. In the housing scope, drainage is enabled to accomodate the flow of used water and rain water from the house which then flowed into the downstream or river as the final disposal place. The purpose of this study is to assess the initial design of the stream viewed from the cost budget plan. Find out whether the alternative design are required, find out the ideal alternative design, and get a comparison between the initial design and the alternative design. The result of this research is the analysis of budget plan, the production cost of initial design with u-ditch and buis concrete material is inefficient with budget of cost Rp. 1.781.350.200,- and then made alternative design buis concrete precast with budget of cost Rp. 1.104.667.700,- . After comparison between initial design and some alternative design, it is known that alternative design that can be recomended to be done is the alternative design with buis concrete precast material because it has lower price, by the difference of profit Rp. 676.672.500,-.

Abstract

The drainage system is one of the most important urban infrastructure. Management quality of a city is reflected in the drainage system quality of the city. To ensure the sustainability of the drainage system, we need a system of drainage management that involves all stakeholders, including the people who reside in it. This study was conducted to determine the organization of the management of the drainage system in the Netherlands, France and Indonesia. Data collected through interviews with the parties related to the management of the drainage system in Indonesia as well as from the literature. There are three models of organization in the drainage system management which is organizations model of government-based, organization model of community-based and organization model of stakeholders-based. In general, the drainage system management in France and the Netherlands is organization model of stakeholders-based, whereas in Indonesia using organizations model of government-based and community-based. Organizations of drainage system management has a very important role, and therefore must involve competent personnel and supported by regulation and sufficient authority. Increased community participation and partnerships between government, private and community must be continued, particularly in terms of maintenance and management of the construction of drainage infrastructure and facilities that have been built.Keywords: organization model, management, drainage system

Abstract

A contract change order (CCO) is a job change activity in a construction project that is carried out during the work implementation period. This study aims to determine the factors that cause contract change orders, analyze the impact given if there is a contract change order and analyze what strategies must be done to resolve the occurrence of contract change orders in the implementation of the Alton Apartment building construction project located in the city of Semarang. The data collected in this study used a semi-structured interview method with competent sources in their field, while the sources for data collection were construction management consultants (MK), contractors & owners. The Strength, Weakness, Opportunity, Threats (SWOT) analysis method is used to determine the right strategy to deal with CCO activities. The conclusion of the study, CCO was caused by an imperfect design that resulted in the achievement of time and costs not being on target, the strategy was obtained by accelerating work, controlling each work and project cashflow and referring back to the wholesale contract that was mutually agreed upon in the event of a dispute.

Kelurahan Pandean Lamper merupakan salah satu daerah rawan banjir di Kota Semarang, karena terletak di DAS Sungai Banjir Kanal Timur. Penanganan terhadap banjir di wilayah tersebut telah dilakukan oleh pemerintah berupa normalisasi sungai dan saluran drainase. Banjir Kanal Timur (BKT) adalah satu sistem pengendali banjir Kota Semarang yang terletak di bagian timur Kota Semarang. Sungai ini memiliki panjang ± 14,50 km. Proyek normalisasi Sungai Banjir Kanal Timur membentang dari hulu di Bendungan Pucanggading hingga berakhir Muara Sungai di Laut Jawa. Dalam tahap I, normalisasi dilakukan sepanjang 6,7 kilometer, dari muara hingga Jembatan Majapahit. Untuk menjamin keberlanjutan pengelolaan normalisasi sungai dan saluran drainase, diperlukan keterlibatan banyak pihak, termasuk partisipasi masyarakat yang bertempat tinggal di dalamnya. Oleh sebab itu warga di kawasan tersebut perlu mendapatkan edukasi bagaimana menjaga keberlanjutan normalisasi sungai dan saluran drainase. Warga Kelurahan Pandean Lamper memerlukan edukasi agar dapat ikut berpartisipasi dalam pemeliharaan sungai dan saluran drainase. Edukasi yang diberikan meliputi pemahaman tentang penyebab dan dampak banjir, penanganan banjir serta pemeliharaan bangunan infrastruktur pengendali banjir. Warga Kelurahan Pandean Lamper masih banyak yang tidak memahami bangunan pengendali banjir yang ada di sekitar lingkungan mereka. Melalui edukasi yang diberikan dalam penyuluhan, diharapkan warga Pandean Lamper bisa memahami peran yang harus dilakukan dalam menjaga keberlangsungan bangunan pengendali banjir. Pandean Lamper Village is one of the flood-prone areas in Semarang City, because it is located in the East Flood Canal River Basin. The government has taken steps to deal with flooding in the area by normalizing rivers and drainage channels. The East Flood Canal (BKT) is a flood control system for the City of Semarang which is located in the eastern part of the City of Semarang. This river has a length of ± 14.50 km. The East Flood Canal River normalization project stretches from the upper reaches of the Pucanggading Dam to the end of the River Estuary in the Java Sea. In phase I, normalization is carried out along 6.7 kilometers, from the estuary to the Majapahit Bridge. To ensure the sustainability of the normalization of river and drainage channel management, it requires the involvement of many parties, including the participation of the people who live in them. Therefore, residents in the area need to receive education on how to maintain the sustainability of normalization of rivers and drainage channels. The residents of Pandean Lamper Village need education so that they can participate in the maintenance of rivers and drainage channels. The education provided includes an understanding of the causes and impacts of floods, flood management and maintenance of flood control infrastructure buildings. There are still many residents of Pandean Lamper Village who do not understand the flood control buildings in their surroundings. Through the education provided in the counseling, it is hoped that the residents of Pandean Lamper can understand the role that must be carried out in maintaining the sustainability of flood control buildings.
