Hydraulic system is one that is widely used in industry, in a mutually sustainable industry between one and the other time is that the main focus. In this study conducted a comparative study between the time and expense incurred by a hydraulic system to determine the effect both of them, in the end the data that obtained its expected can be utilized for the development of industry in Indonesia."

"The measurement of susoended sediment, particularly in field settings, is important in the documentation of sediment transport and deposition. Many measurement techniques have been used euth varying degrees of success. "

"Laporan ini menyelidiki temuan pada pengujian sifat hidrolik dari Stone Wool untuk melihat kinerjanya sebagai media filter dengan menggunakan alat setup eksperimen baru. Setup akan dirancang sedemikian rupa sehingga kepala hidrolik dan panjang filter dapat divariasikan untuk mengamati laju aliran yang dihasilkan oleh metode ini, dan kemudian konduktivitas hidrolik akan dihitung. Panjang media filter stone wool yang digunakan ada dua yaitu 9,6 cm dan 16 cm, serta tinggi tekan bervariasi dari 117 cm sampai 74 cm sampai 44 cm. Hasilnya menunjukkan bahwa konduktivitas hidrolik lebih besar pada penampang yang lebih panjang dan, secara umum, dengan tinggi tekan hidrolik yang lebih tinggi, dengan temuan berkisar antara 0,216 cm/s hingga 0,408 cm/s. Hasil ini mungkin disebabkan oleh laju aliran yang tidak konsisten yang diamati selama percobaan, yang menyebabkan terciptanya outlier. Namun, hasil ini memperjelas seperti apa bentuk Stone Wool yang memiliki potensi terbesar sebagai media filter. Informasi lebih lanjut akan diberikan dalam laporan ini.

This paper investigates the findings on testing hydraulic properties of stone wool to see its performance as a filter media by using a new experimental setup. The setup will be designed so that the hydraulic heads and length of the filter can be varied in order to observe the flow rate produced by this method, and then hydraulic conductivity will be calculated. There were two lengths of stone wool filter media used, 9.6 cm and 16 cm, and the hydraulic heads varied from 117 cm to 74 cm to 44 cm. The results demonstrate that the hydraulic conductivity is greater on the longer section and, in general, with higher hydraulic head, with findings ranging from 0.216 cm/s to 0.408 cm/s. These results may be due to the inconsistent flow rates observed during the experiment, which led to the creation of outliers. However, these results have made it clear which types of stone wool have the greatest potential as filter media. More information will be provided in this report."

"ABSTRAKThe stable pools formed by spur dikes can be a significant factor for improving aquatic habitat in unstable degraded streams. Prediction of the volume and geometry of the scour hole associated with a spur dike yields information that is valuable for assessing the potential benefit to the aquatic habitat. Volumes of the scour hole in the vicinity of model spur dikes were measured in a laboratory flume under clear-water overtopping flows. Spur dike length, flow depth and shear velocity ratio were varied in the experiments and found to significantly influence the volume of the scour hole. For overtopping flows, the ratio of the flow depth to the spur dike height was found to be an important control on the geometry of the resulting scour hole. At higher flow depth to spur dike height ratios, the location of the maximum depth of scour changed from the upstream point of the dike toward the channel bank and caused a secondary scour zone to form downstream of the spur dike. A preliminary technique is proposed to predict the volume of scour for spur dikes perpendicular to the bank."

"The book serves as a unique integrated platform, which not only describes the design methodology of electro-hydraulic actuation systems but also provides insights into the design of the servo valve, which is the most important component in the system. It presents a step-by-step design process, comparative tables, illustrative figures, and detailed explanations. The book focuses on the design and testing of electro-hydraulic actuation systems, which are increasingly being used in motion control applications, particularly in those where precision actuation at high operational rates is of prime importance. It describes in detail the design philosophy of such high-performance systems, presenting a system used as a physical test setup together with experimental results to corroborate the calculations. Of particular interest are the electro-hydraulic servo valves that form the heart of these actuations. These valves are complex and not much data is available in open literature due to OEM propriety issues. In this context, the book discusses the elaborate mathematical models that have been derived and an approach to validate the mathematical models with test results. Presenting the complex methodology in simple language, it will prove to be a valuable resource for students, researchers, and professional engineers alike."
