ABSTRACT Making a budget plan in a project is often done manually which of course takes a long time to complete. In determining the budget plan, there are many types of work such as preparatory work, reinforced concrete work, and steel work, so it is quite difficult to work on. The budget plan can only be done by experts in the field, so it requires quite expensive processing costs. From the problems described above, we need a program that can simplify the calculation of the budget plan, especially in steel works (WF Beam). In this case, we created a program using the python language that needed to input some data such as rod length, number of bars, type of steel, steel prices, and work wages so that it would immediately produce a value or amount of the volume and price of a steel work that could help contractors especially steel subcontractors in calculating steel work (WF Beam). Keywords: python, RAB, WF beam, work volume, job price. ABSTRAK Pembuatan rencana anggaran dan biaya dalam sebuah proyek sering dilakukan secara manual yang tentunya membutuhkan waktu yang cukup lama untuk menyelesaikannya. Dalam menentukan rencana anggaran dan biaya, ada banyak jenis pekerjaan seperti pekerjaan persiapan, pekerjaan beton bertulang, dan pekerjaan baja, sehingga cukup sulit untuk dikerjakan. Rencana anggaran dan biaya juga hanya bisa dikerjakan oleh tenaga ahli pada bidang tersebut sehingga membutuhkan biaya pengerjaan yang cukup mahal. Dari permasalahan yang sudah dijabarkan diatas maka dibutuhkan sebuah program yang dapat mempermudah perhitungan rencana anggaran dan biaya khususnya di pekerjaan baja (WF Beam). Dalam hal ini, kami membuat sebuah program menggunakan bahasa python yang perlu menginputkan beberapa data seperti panjang batang, jumlah batang, jenis baja, harga baja, dan upah pekerjaan sehingga  akan langsung menghasilkan nilai atau besaran dari volume dan harga suatu pekerjaan baja yang dapat membantu kontraktor khususnya sub kontraktor baja dalam melakukan perhitungan pekerjaan baja (WF Beam). Kata kunci: python, RAB , WF beam, volume pekerjaan, harga pekerjaan.

It is shown that critical flow Venturi nozzles need time intervals, i.e., more than five hours, to achieve steady state conditions. During these intervals, the discharge coefficient varies gradually to reach a value inherent to the pressure ratio applied. When a nozzle is suddenly put in the critical condition, its discharge coefficient is trapped at a certain value then afterwards approaches gradually to the inherent value. Primary calibrations are considered to have measured the trapped discharge coefficient, whereas nozzles in applications, where a constant pressure ratio is applied for a long time, have a discharge coefficient inherent to the pressure ratio; inherent and trapped coefficients can differ by 0.03–0.04%.

Contingent Approach

Understanding how firms differ is a central challenge for both theory and practice of management. For a long time, Porter’s (1985) value chain was the only value configuration known to managers. Stabell and Fjeldstad (1998) identified two alternative value configurations. First, a value shop schedules activities and applies resources in a fashion that is dimensioned and appropriate to the needs of client problems, while a value chain performs a fixed set of activities that enables it to produce a standard product in large numbers. Examples of value shops are professional service firms, as found in medicine, law, architecture and engineering. Next, a value network links clients or customers who are or wish to be interdependent. Examples of value networks are logistic companies, telephone companies, retail banks and insurance companies. In this chapter, we apply the contingent approach to systems outsourcing by making the outsourcing decision dependent on the value configuration of the enterprise. We present the three different value configurations – the value chain, the value shop, and the value network. Next, the three different value configurations are compared according to key characteristics, e.g. use of information systems. Then, we take a look at interfirm relations to be able to identify areas for outsourcing, and value configuration as a determinant and predictor for the extent of outsourcing. Finally, we discuss levels of strategy and we introduce the Y-model for IS/IT strategy work.

The Mean

A solution to the dispersion of small particles suspended in a turbulent fluid is presented, based on the approximation proposed by Phythian for the dispersion of fluid points in an incompressible random fluid. Motion is considered in a frame moving with the mean velocity of the fluid, the forces acting on the particle being taken as gravity and a fluid drag assumed linear in the particle velocity relative to that of the fluid. The probability distribution of the fluid velocity field in this frame is taken as Gaussian, homogeneous, isotropic, stationary and of zero mean. It is shown that, in the absence of gravity, the long-time particle diffusion coefficient is in general greater than that of the fluid, approaching with increasing particle relaxation time a value consistent with the particle being in an Eulerian frame of reference. The effect of gravity is consistent with Yudine's effect of crossing trajectories, reducing unequally the particle diffusion in directions normal to and parallel to the direction of the gravitational field. To characterize the effect of flow and gravity on particle diffusion it has been found useful to use a Froude number defined in terms of the turbulent intensity rather than the mean velocity. Depending upon the value of this number, it is found that the particle integral time scale may initially decrease with increasing particle relaxation time though it eventually rises and approaches the particle relaxation time. It is finally shown how this analysis may be extended to include the extra forces generated by the fluid and particle accelerations.

St. Petersburg possesses a large number of bridge constructions operated throughout a long time. Mainly these are objects made of reinforced concrete. Among bridges of the city there is a set of unique constructions. Specifics of bridges maintenance in megalopolis environment are characterized by difficult climatic and technogenic conditions. It causes emergence and development of numerous defects and damages in designs. For development of scientifically based techniques of assessment and forecasting of technical condition of the operated bridge constructions (in particular, reinforced concrete) the authentic and urgent analysis of this state is necessary. It is possible to execute it, having formulated the corresponding criteria and methods of assessment, and also having created a certain methodology of the analysis, as it is executed in the present article. Six evaluation criteria on which it is possible to carry out complex diagnostics of bridges of St. Petersburg are designated. Results of the analysis confirm need of special approaches to operation of megalopolises bridges park and also on a large number of constructions with extremely unsatisfactory technical condition.

“Gotong-Royong” (mutual assistance of Indonesia) According to Sukarno in Max Scheler’s Axiology Perspective aims to find analytically the objective meaning of the principle of gotong-royong in the perspective of axiology. Axiology selected as an object to be formal because this research focused on “gotong-royong” as a typical value of Indonesia. This theme is expected to contribute to the life of the Indonesian people today who seem to live in a crisis of mutual cooperation in various fields. Sukarno summarizes Pancasila in a single value, namely the "gotong-royong" or he describes as Ekasila. The essence of Pancasila finds a great challenge today.The research in this dissertation is a qualitative study philosophy. The research model used a qualitative research by conducting a literature study. Hermeneutics is then used to search for meaning in this study. Methodical elements used in this study are: verstehen, historical analysis, analytic language, and heuristics. Sukarno's speech will be studied by following the hermeneutics of Dilthey. The results of the analysis of Dilthey then will be the material that will discussed from the standpoint of axiological objectivism of Max Scheler.The meaning of “gotong-royong” of Soekarno found in this research is to work together, help each other, shoulder to shoulder, cooperation, deliberation, and mutual respect as a nation. The “gotong-royong” was not the result of subjective feelings of Sukarno. The value of gotong-royong is exist without speech of Soekarno, and attached to Indonesian. Pancasila is not created by Sukarno or the founding fathers. Sukarno, in the language of Scheler, precisely found the values of Pancasila and gotong-royong that has lived a long time in the Earth Indonesia. Gotong-royong as a value, in this line of thought Scheler fixed and objective. The practice of gotong-royong appears in the shared ethos..

This study aims to explore the strategy of gaining user trust in a crowdsourcing startup based on the Desirability Business Model. This study may uncover the user trust of crowdsourcing startup which may help startup enhancing engagement and participation from crowd. The difficulties in crowdsourcing is engage user to stay with application for a long time, so this study try to help startup finding indicators to gain user trust.  This paper first propose a model to depict the effect of four parameter of Desirability Business Model with User Trust, which may influence Gojek users, then using Stratified Random Sampling Technique with a total sample of 97 people which are the subject is the society in Surabaya that in a month is at least 2 times and a maximum of more than 10 times using the Go Ride application on the Gojek company. The data collection used a questionnaire distributed through google form and social media such as Line and WhatsApp, while for the tabulation stage, it will be processed using Smart PLS-SEM. The results of this study show that of the four indicators in the Desirability Business Model variable only two indicators have a positive effect on user trust firstly, Value Proposition consisting of Performance, Design, Accessibility, Convenience, Risk Reduction, Cost Reduction and Newness then secondly, Channels consisting of Awareness, Evaluation, Purchase and After Sales. To gain user trust on the crowdsourcing startup, business owners can focus on two things firstly, provide beneficial value of the product or service offered to the user and secondly, design channel which can make business communicates with its users to convey a value proposition.

Hardening Coefficient

The use of fiber in cement materials is a promising and effective replacement for bar reinforcement. A wide range of fiber-reinforced concretes based on composite binders with increased impact strength characteristics have been developed. The synthesized composites included the composite binder made of Portland cement, silica, and carbonate additives. Basalt and steel were used as fibers. The nature of the influence of the composition and manufacturing technology of cement composites on the dynamic hardening coefficient has been established, while the growth of these indicators is achieved by creating a denser interfacial transition zone between the cement paste, aggregate, and fiber as a result of improving the homogeneity of the concrete mixture and controlling the consistency. Workability indicators (slump flow up to 730 mm; spreading time up to a diameter of 50 cm is up to 3 s) allow them to be classified as self-compacting concrete mixtures. An increase in the values of the impact strength coefficient by a factor of 5.5, the dynamic hardening coefficient by almost 70% as a result of interfacial interaction between fibers and binder matrix in the concrete composite, as well as absorption of impact energy by fiber, was revealed. The formula describing the effect of the loading rate on the coefficient of dynamic hardening of fiber-reinforced concrete has been refined. The fracture processes of the obtained materials have been established: after the initiation of primary cracks, the structure of the composite absorbs impact energy for a long time, while in the inelastic range (the onset of cracking and peak loads), a large number of secondary cracks appear.

To comprehend the value that information technology provides to organizations, we must first understand the way a particular organization conducts business and how information systems affect the performance of various component activities within the organization. Understanding how firms differ is a central challenge for both theory and practice of management. For a long time, Porter’s (1985) value chain was the only value configuration known to managers. Stabell and Fjeldstad (1998) have identified two alternative value configurations. A value shop schedules activities and applies resources in a fashion that is dimensioned and appropriate to the need’s of the client’s problem, while a value chain performs a fixed set of activities that enables it to produce a standard product in large numbers. Examples of value shops are professional service firms, as found in medicine, law, architecture and engineering. A value network links clients or customers who are or wish to be interdependent. Examples of value networks are telephone companies, retail banks and insurance companies. A value configuration describes how value is created in a company for its customers. A value configuration shows how the most important business processes function to create value for customers. A value configuration represents the way a particular organization conducts business.

Corner retaining walls are one of the most common structures of waterworks. Most of them were designed and built several decades ago and have been in operation for a long time. In some cases, there is a deviation from the design prerequisites and the strengthening of reinforced concrete structures of retaining walls is required. The main reason for these deviations is incomplete consideration of the characteristic features of retaining wall structures (including horizontal inter-block joints and secondary inclined cracks), as well as the nature of the loads acting on them. As a result, design horizontal transverse reinforcement is practically not installed in retaining walls that is not required by calculation based on traditional calculation methods.Traditional reinforcement schemes for retaining walls do not provide for the presence of horizontal inter-block joints and horizontal transverse reinforcement. As a result of the research carried out,the method for calculating the stress-strain state and strength of reinforced concrete structures of corner retaining walls with inter-block joints has been improved taking into account secondary stresses. Reinforcement schemes for retaining walls have also been improved.
