Abstract

Fatty alcohol is a derivative of vegetable fats and animal oils, and is a non-oil and gas export commodity that is needed by various industries such as perfumes, cosmetics, pharmaceuticals, food and beverages. demand for alcohol is increasing every year. The import of alcohol has been carried out, but the domestic demand for alcohol has not been met. This has led to the establishment of a fatty alcohol factory with crude palm oil as the main raw material to meet these needs. The plant has an annual production capacity of 130,000 tons and will be established in Pelintung, Dumai. The production of fatty alcohols is carried out through three processes: pretreatment, transesterification and hydrogenation. The main equipment of this tool is designed as a hydrogenation reactor, which functions to react methyl ester with hydrogen with the help of a CuCr catalyst. The operating temperature used is 1700C with an operating pressure of 100 bar. The hydrogenation reactor is 4,006 m (157.72 in) high and uses skirt supports. Factory economic analysis is carried out to determine the feasibility of the factory to be built. Based on the results of the economic feasibility analysis of the factory, the Fatty alcohol factory is feasible to be built with IRR 24.164%, ROI 27.35% and BEP 58%.Keywords: Crude palm oil, economic analysis, fatty alcohol, hydrogenation, transesterification

Abstract

Abrasion and sedimentation are events that usually arise due to the movement and accumulation of material carried by ocean currents. Severe damage occurred in coastal areas such as on Bengkalis Island. Research on the initial motion of grains, especially on peat material, is very interesting to study. This study aims to analyze the relationship between flow velocity and grain diameter at the beginning of the movement of peat material grains. The initial motion of the peat material will be compared with the movement of the sand material. Modeling to analyze the initial motion of the grains on peat soil using Armfield Sediment Transport Demonstration Channel as flume. The flume velocity was varied starting from the lowest and symbolized by U, namely 1-7 (U=0.009890.10112 m/s) speed for peat material, and 4-10 (U=0.03973-0.18900 m/s) speed for sand material. The results showed that peat material experienced easier grain movement than sand material. This is due to the smaller spesific gravity of peat than sand. Proven based on the shield graph, the results of the critical shear stress on the sand sample No. 10 is below the shield graph, and on the peat material No. 10 is above the shield chart. Based on visual observations on peat sediments, it is found that the movement starts from the type of laminar flow, while in the sand sediments there is movement in the type of turbulent flow. Keywords : peat, flow velocity, initial motion, critical shear stress, shield graphic

Abstract

Internet Service Providers (ISP), better known as internet service providers, are manufacturers or institutions that provide internet connection services and other related services. To monitor the stability of the Provider network, a Quality of Service (QoS) parameter is needed as a standard for testing the quality of internet services, for example when uploading videos, the traffic load on the internet network will increase. . Quality of Service (QoS) is carried out by monitoring the access speed of Telkomsel providers with the delay parameter as a determining point. The results of Quality of Service research when uploading videos with 360p resolution for 3 days using a Telkomsel provider in the morning obtained the lowest delay value with an average of 1.17 milliseconds (ms) and the highest delay value was obtained during the day 1.81 milliseconds (ms). with good quality according to TIPHON standard. From these results it can be concluded that the higher the delay value of a data, the slower the network speed.Keywords : ISP, Upload, Delay, QoS
