PERENCANAAN SISTEM PLAMBING DAN HIDRAN KEBAKARAN PADA PROYEK PEMBANGUNAN HOTEL PESONA ALAM

Hotel Pesona Alam merupakan salah satu hotel yang terletak di kawasan Cisarua, Bogor. Perencanaan system plambing dan Hidran Kebakaran yang memadai diperlukan untuk menunjang kenyamanan dan keamanan aktivitas pengunjung Hotel. Perhitungan perencanaan air bersih maupun kotor, digunakan metode Unit Beban Alat Plambing. Penggambaran isometri jaringan perpipaan dan penentuan diameter pipa air bersih dibantu dengan software Pipe Flow Expert. Berdasarkan perhitungan, didapatkan kebutuhan air bersih per hari pada Hotel Pesona Alam adalah 230 m3/hari dengan diameter pipa air bersih yang diperlukan sebesar 0.5”, 0.75”, 1”, 1.25”, dan 2”. Perkiraan air buangan yang dihasilkan sebesar 207 m3/hari dengan diameter air buangan yang digunakan sebesar 1.25”, 1.5”, 2”, 2.5”, 3” dan 4”. Sedangkan untuk sistem hidran kebakaran digunakan 3 jenis hidran kebakaran yaitu pillar hydrant, fire hose reel, dan sprinkler. Kebutuhan air bersih untuk pemadam kebakaran sebesar 270 m3.

Fashioning fire hose: Design in the liminal spaces between product lives

Among the scrapheap of society’s unwanted materials lies a vast and wondrous world of fashion potential. In the liminal phase between a product’s rejection and its fate as landfill, designers are called on to create a positive alternative. The upcycling process encourages designers to consider how they might release the past social lives of products to uncover the design potential of new creations. Upcycling introduces the dimensions of time, designer knowledge and skills into the creation of a garment or accessory. This practice makes a place in fashion for challenging the hypercycle of consumption and the new by valuing fabrics that can tell stories of their past lives in other times and places. In this article I examine the appropriation of retired fire hose in the fashion industry by the company Elvis & Kresse. In the framework of Arnold van Gennep’s ritual phases of transition, namely the ‘pre-liminal’, ‘liminal’ and ‘post-liminal’, of critical interest is the second or liminal phase, in which the retired fire hose risks becoming obscure and permanently separated from reality but is instead incorporated into luxury bags and belts. This article advances the perception of the liminal as a place for collecting ‘polluting’ materials and, via design, reintroducing them into society. In my focus on this company and on fire hose as a fashion textile, I probe the liminal threshold as a place of creative experimentation and a powerful framework for understanding and structuring product transitions. The ability to change how an item is perceived by fracturing its sense of time and place highlights the importance of upcycling in tackling many of the current criticisms levelled at fashion while introducing new roles for designers as facilitators of transformation.

Investigation of the dependence of the internal disruptive pressure in a fire hose on geometric densities on the warp and the weft of its woven reinforcing frame

In this article, based on the obtained formula for calculating the strength of a pressure fire hose(PFN) under the action of internal hydraulic pressure, the dependence of the disruptive pressure in alatex pressure fire hose, designed for an operating pressure of 1.6 H, on such parameters as geometric densities on the warp and the weft, is studied. As a result of the studies, the pattern of decreasing the disruptive pressure of a fire hose with an increase in the geometric densities on the warp and the weft of a reinforcing frame of a pressure fire hose was experimentally established. When designing new fire hoses, it is important to take into account the significant dependence of the disruptive pressure on the geometric densities on the warp and the weft of a reinforcing frame. Recommendations are given on choosing the optimal parameters for a woven reinforcing frame of latex pressure fire hoses with a diameter of 77 mm.

Determining the dissipative properties of a flexible pipeline’s material at stretching in the transverse direction taking its structural elements into consideration

This paper reports an experimental study that determines the dissipative properties of a pressure fire hose, the type of «T», whose inner diameter is 77 mm, under the static load conditions, taking into consideration the structural elements of the hose in the transverse direction. For this study, experimental samples were separated from the different sections of the hose. The study involved both the outer fabric reinforced frame and the internal waterproofing rubber layer of the pressure fire hose. A series of field experiments were carried out while stretching the samples under the conditions of static loading-unloading cycles. The tests included 7 cycles, which were carried out in a two-minute interval for the material of the hose. The study results showed that during the first two to three cycles, the materials manifest a short-term creep that stabilizes under modes 4‒7. The results from experimental research were approximated by polynomial trend lines. The deformation of samples demonstrated the curves that, under the conditions of cyclic loading and unloading, formed hysteresis loops. When analyzing the appropriate curves, it was found that, first, during the first two-three loading-unloading cycles the area of the hysteresis loops decreases, second, the inclination angle of hysteresis loops also decreased during each subsequent loading-unloading cycle. It was established that the dissipation coefficients of the hose material stretched in the transverse direction are significantly reduced under the first three test modes in the range from 0.49 to 0.37. At subsequent tests (cycles 4–7), dissipation coefficients stabilize at the level of 0.18 for the reinforced frame, and 0.316 for the rubber layer
